SIM Card Activated but Not Working? Fix Calls, Texts & Data (2026)

Your SIM says it is active or shows signal bars, but calls, texts, or mobile data still fail. Test each service separately, then follow the fixes below from the least disruptive step to carrier escalation. This guide focuses on a SIM that is detected or activated. If your phone says “No SIM” or “SIM not detected,” use the general SIM-not-working guide.

First, Identify What Is Actually Failing

Reviewed September 2026: “Active,” signal bars, and a detected SIM do not prove that calls, texts, and mobile data are all working. Test each service separately before changing settings.

What you see	Check first
Signal bars, but mobile data fails	Turn Wi-Fi off, confirm mobile data and the default data line are enabled, then check the carrier’s official APN guidance.
Data works, but calls or texts fail	Confirm the correct voice/SMS line, VoLTE or Wi-Fi Calling requirements, and carrier provisioning.
Calls, texts, and data all fail after activation	Check for an outage, account hold, incomplete activation, carrier lock, or an unsupported device.
“No SIM” or “SIM not detected”	This is a detection problem. Use the general SIM-not-working guide for tray, card, and hardware checks.

Before a network reset: save Wi-Fi passwords and note any carrier-provided APN values. A network reset removes saved connections and may not fix an account or carrier-side problem.

Key Takeaways

• A SIM card can show “network active” yet fail if activation isn’t complete, APN settings are wrong, or network bands don’t match.
• Start with quick actions: toggle Airplane mode, reseat SIM, check your balance, reset APN and network settings.
• Test SIM in another device to isolate if the fault is with the SIM or your phone.
• An eSIM can bypass a damaged physical tray, but it cannot fix a carrier outage, an account hold, a carrier lock, or unsupported radio bands.

Understanding the Problem

“Network Active” is not a universal status label, and its meaning varies by phone and carrier. Signal bars usually show that the phone can see a cellular network; they do not confirm that the line is provisioned for calls, texts, and mobile data.

A visible network connection alone does not confirm that every service on the line has been authorized.

The Two-Step Connection Process:

Step 1: Registration (What "Network Active" means)

• The phone and SIM exchange subscriber credentials with the carrier network
• The phone may then display the carrier name or signal bars
• The status indicator can appear before calls, texts, and data are fully available
• Timing varies by carrier, coverage, roaming status, and device

Step 2: Authorization (What's actually broken)

• The carrier checks whether the line, plan, device, and requested service are allowed
• Voice, SMS, and data may be provisioned separately
• The network completes authentication and service provisioning
• If activation remains incomplete, only the carrier can confirm or refresh the line

Real-World Analogy

Think of airport security:

• Registration = Passport scan confirms your identity
• Authorization = Valid boarding pass lets you actually fly

You can pass through passport control (registration) but still get stopped at the gate without a boarding pass (authorization).

Why This Gap Happens

Your phone got "registered" but authorization failed due to:

1. Carrier backend delay: Their database hasn't updated your SIM permissions yet
2. Wrong APN settings: Like having the wrong gate number on your boarding pass
3. Carrier authentication or provisioning: The line is registered, but one or more services are not authorized correctly
4. Network mode mismatch: Trying to use 5G when tower only offers 4G
5. Account issues: Suspended service, zero balance, or expired plan

Common Scenarios When This Occurs

After traveling internationally

• SIM registers on foreign towers but roaming not enabled
• Wrong network mode for local frequenciesBrand new SIM activation
• Activation time varies; use the deadline stated by your carrier and contact support if it passes
• IMSI not yet added to billing databaseAfter phone OS update
• An update may refresh carrier settings or change a network preference
• A carrier-settings update or restart may be required after an OS update

Switching between SIM cards

• Phone caches old network preferences
• Needs restart to clear previous SIM's settingsAfter suspension/reactivation
• Account reinstated but network authentication not refreshed
• Carrier support may need to refresh the line’s network registration

Common Causes of SIM Connectivity Failure Despite Active Status

SIM Card Activation Issues

Carriers often need time to fully provision (update their network database) after issuing or replacing a SIM. Until this completes, calls/data may be blocked even though the SIM registers.

Incorrect APN Settings

The Access Point Name (APN) tells your device how to connect to your carrier’s data network. One wrong character can block mobile data entirely. Compare your APN to the one listed on your carrier’s site and reset to default if unsure.

Outdated Cellular Firmware

Cellular firmware controls how your phone’s radio talks to network bands. Outdated versions can mismanage frequency switching or authentication. Updating often solves subtle connectivity bugs.

Network Mode / Band Compatibility

Auto-switch between 4G/5G can fail if the local tower doesn’t support your current mode. Selecting 4G/LTE can sometimes stabilize service where the carrier and device still offer that option, especially while roaming.

Poor SIM Slot Condition

Dust, moisture, or bent pins can disrupt the tiny electrical contacts that let the SIM communicate.

Carrier or Regional Restrictions

Country locks, roaming bans, or devices not approved by the local regulator can cause service denial despite registration.

Quick Fix Checklist – Try These in Order

Follow these in order and retest calls, texts, and mobile data after each step. Menu names vary by device and carrier:

Step 1: Toggle Airplane Mode + Restart

Best for: A temporary network-registration glitch. Restarting forces a fresh connection without erasing settings.

How to do it:

1. Turn Airplane mode ON, wait 30 seconds
2. Turn Airplane mode OFF
3. Fully restart your phone (hold power button → Restart)
4. Wait 60 seconds after reboot
5. Test: Open browser and load any website

✓ If this works: You had a temporary tower handshake glitch. Problem solved!

Step 2: Remove & Reseat SIM

Best for: A physical SIM that may be loose, dirty, or misaligned. Skip this step for eSIM.

How to do it:

1. Power off completely (not just Airplane mode)
2. Eject SIM tray with pin or paperclip
3. Check gold contacts – wipe gently with dry cloth if dusty
4. Inspect SIM slot – blow out any dust
5. Reinsert SIM firmly until it clicks into place
6. Power on, wait 60 seconds

If this works: Physical contact issue was the culprit.
If SIM looks scratched/bent: Skip to Step 7 (test in another device) – you may need SIM replacement.

Step 3: Verify Activation & Balance

Best for: A new, prepaid, recently ported, suspended, or reactivated line.

How to check:

• Check the carrier account: Use the carrier’s official app, website, or support number to confirm activation, plan status, and balance. Short codes are carrier- and country-specific.
• Or use carrier app: Log in and verify account status
• Confirm these 3 things:SIM status shows "Active" (not "Suspended" or "Pending")Data balance is not zeroNo outstanding payment due

If account inactive: Pay outstanding balance or contact carrier billing.

Step 4: Reset APN to Default

Best for: Mobile data that fails while calls or texts still work. Use only APN values published by your carrier.

How to reset:

For Android:

1. Settings → Network & Internet → Mobile Network
2. Access Point Names (APN)
3. Tap 3-dot menu → Reset to default
4. Restart phone

For iOS:

1. Settings → General → Transfer or Reset iPhone → Reset
2. Reset Network Settings
3. Enter passcode, confirm
4. After the restart, turn Wi-Fi off and test mobile data. APN editing and automatic configuration depend on the carrier.

If this works: You had incorrect APN configuration.
Pro tip: Screenshot your APN settings BEFORE resetting, in case you need to restore custom settings later.

Step 5: Reset Network Settings

Best for: Persistent software or network-profile problems after the simpler checks fail.

WARNING: This will erase saved Wi-Fi passwords and Bluetooth pairings. Write them down first!

How to reset:

Android: Settings → System → Reset Options → Reset Wi-Fi, Mobile & Bluetooth → Reset Settings

iOS: Settings → General → Transfer or Reset iPhone → Reset → Reset Network Settings

After reset:

• Phone will restart
• Reconnect to Wi-Fi manually
• Mobile data should auto-configure

If this works: You had corrupted network configuration files.

Step 6: Switch Network Mode Manually

Best for: Unstable coverage or roaming where the carrier and device let you select 4G/LTE manually.

How to switch:

Android: Settings → Network & Internet → Mobile Network → Preferred Network Type → Select LTE/4G Only

iOS: Settings → Cellular → Cellular Data Options → Voice & Data → Select LTE

When this helps most:

• Traveling internationally (foreign towers may not support all modes)
• Rural areas with spotty 5G coverage
• Phone constantly switches between 5G and 4G

If this works: Your phone was stuck trying to connect to unavailable network mode.

Step 7: Test SIM in Another Device

Time: 5 minutes
Diagnostic test (determines if problem is SIM or phone)

How to test:

1. Borrow a friend's unlocked phone (must be same carrier or unlocked)
2. Insert your SIM
3. Wait 60 seconds
4. Try making a call or browsing

Results:

SIM works in other phone:

• Problem = Your phone (SIM slot damage, software issue, IMEI block)
• Next step: Contact phone manufacturer or repair shop

SIM fails in other phone too:

• Problem = Your SIM card (physically damaged or not provisioned)
• Next step: Contact carrier for SIM replacement

Still Not Working After All Steps?

Contact your carrier support if:

• You've tried all 7 steps above
• SIM is brand new (may need manual provisioning)
• Account shows active but no service

Ask them to:

1. "Refresh my SIM profile on the network"
2. "Please confirm that my line is provisioned for voice, SMS, and data, then refresh its network registration"
3. "Check if my device IMEI is blacklisted"

Carrier fix time: Usually resolved in 10-30 minutes over phone.

When to Fix It Yourself vs. Contact Carrier vs. Visit Repair Shop

Not sure if you should keep troubleshooting or call for help? Use this decision tree:

FIX IT YOURSELF (Continue with Quick Fix steps above)

If ALL these are true:

• ✓ SIM worked fine yesterday, stopped working today
• ✓ You're comfortable navigating phone settings
• ✓ No physical damage to phone (not dropped, no water exposure)
• ✓ You have 15-20 minutes to try troubleshooting steps

Most likely causes you can fix:

• Temporary network glitch (Airplane mode fix)
• Dust/poor SIM contact (reseat SIM)
• Wrong APN settings (reset APN)
• Corrupted network config (reset network settings)

Resolution time depends on whether the problem is on the phone, SIM, account, or carrier network.

CALL YOUR CARRIER IMMEDIATELY (Don't waste time troubleshooting)

If ANY of these are true:

Brand new SIM card never worked

• Likely: Activation not completed in their system
• They need to: Manually provision your SIM in backend database
• Fix time: 10-30 minutes over phone

Error message says "SIM Not Provisioned" or "Invalid SIM"

• Likely: Your SIM not registered in carrier's network
• They need to: Add your IMSI to their authorization system
• Fix time: 15 minutes

SIM works in other phones but not yours

• Likely: Your device IMEI is blacklisted or restricted
• They need to: Check IMEI status and remove blocks
• Fix time: 20-40 minutes (may need escalation)

Account suspended or billing issue

• Likely: Service disconnected due to payment
• They need to: Confirm payment received and reactivate
• Fix time: 5-15 minutes

Just ported number from another carrier

• Likely: Port not completed correctly
• They need to: Verify port-in request and force completion
• Fix time: 30 minutes to 24 hours

What to ask carrier support:

1. "Can you confirm my SIM is fully activated and provisioned?"
2. "Please refresh my SIM profile on the network"
3. "Can you check if my device IMEI is blacklisted?"
4. "Can you manually reset my network authentication?"

VISIT REPAIR SHOP / REPLACE DEVICE

If ANY of these are true:

SIM slot is visibly damaged

• Signs: Bent/broken pins, loose tray, won't click into place
• Cost: $50-150 repair (or use eSIM instead if device supports it)

Phone dropped from height or water damaged

• Signs: SIM randomly disconnects, other features also broken
• Cost: $100-300 repair or device replacement

Multiple different SIM cards all fail in your device

• Signs: Borrowed 3+ SIMs from friends, none work
• Likely: SIM reader hardware failure
• Cost: $60-200 repair

Physical damage to SIM card itself

• Signs: Scratches on gold contacts, bent/cracked, warped
• Solution: Request free SIM replacement from carrier (usually $0-10)

Device is carrier-locked to different network

• Signs: Says "SIM not supported" or "Contact carrier to unlock"
• Solution: Request an unlock from the original carrier; eligibility and processing time vary

eSIM emergency backup: If your physical SIM slot is broken but repair will take days:

• Check the exact model number in the manufacturer’s specifications and confirm that the eSIM feature is enabled for its sales region
• Choose a current eSIM plan after checking coverage, validity, price, and refund terms
• Bypass the physical tray if the phone’s eSIM hardware and cellular radio still work
• Install over trusted Wi-Fi and test mobile data before relying on it

Advanced Troubleshooting When Quick Fixes Don’t Work

Update Device & Cellular Firmware

Install pending OS updates and seek carrier firmware updates for your model.

Manual DNS Input

A custom DNS server does not repair SIM activation or carrier authentication. Leave DNS automatic unless your carrier specifically asks you to change it; first verify the default voice/data line, mobile data, and roaming settings.

Physical SIM Inspection

Check under bright light for scratches, dirt, or warping. Clean gently.

Carrier Network Refresh/Reprovision

Ask support to reset your SIM profile in their backend.

Hardware Inspection

If SIM slots or antenna boards are damaged, professional repair is required.

Special Considerations for Travelers and Digital Nomads

International travel multiplies SIM connectivity problems. Here's how to avoid common pitfalls:

Scenario 1: "Network Active" After Landing Abroad, But No Data

What's happening: Your phone registered on local towers but can't connect due to frequency band mismatch.

Example:

• Your phone was sold for a different region
• The exact model may support only some bands used by the destination carrier
• The phone may register on a network but still deliver unstable or unavailable service

Quick fix:

1. Go to Settings → Mobile Network → Preferred Network Type
2. Switch from "5G/LTE Auto" to "4G/LTE Only"
3. Wait 30 seconds
4. Test data connection

Prevention before travel:

• Look up the exact model number—not only the marketing name—on the manufacturer’s specifications page
• Compare its LTE/5G bands with the destination carrier’s published bands
• If the device lacks the required bands, use a compatible device; switching from a physical SIM to eSIM does not add radio-band support

Scenario 2: Swapped to Local SIM, Phone Still Tries Home Network

What's happening: Your phone cached previous SIM's network preferences and won't switch.

Common mistake: Travelers pop out old SIM, insert new SIM, expect instant connection-but phone is still "looking" for home carrier.

Correct procedure:

1. Power off completely (not just SIM swap while on)
2. Remove old SIM
3. Insert new local SIM
4. Power on (this forces phone to re-scan networks)
5. Go to Settings → Network Operators → "Search Networks"
6. Manually select local carrier (e.g., "AIS Thailand")
7. After connected, set back to "Automatic"

Time saved: 15-30 minutes of confused troubleshooting

Pro tip: Set a phone reminder: "After SIM swap → Restart phone before troubleshooting!"

Scenario 3: Roaming "Works" But Costs $15/MB

What's happening: Your home carrier's roaming activated successfully-but at brutal rates.

Example scenario:

• A traveler arrives abroad with home-carrier roaming enabled
• Phone connects (yay!)
• Uses data-heavy video without checking the roaming rate
• Receives an unexpectedly high roaming bill

Why travelers prefer eSIM for international trips:

When eSIM makes most sense:

• Multi-country backpacking (Thailand → Vietnam → Cambodia)
• Emergency connectivity (SIM failed, need data NOW)
• Business travelers (no time to find SIM shops)
• Digital nomads (tired of physical SIM hassles every month)

Example Scenario: Physical SIM Failure in Bangkok

Example scenario (not a customer testimonial): A traveler lands late, the home SIM displays a network, but mobile data is unavailable for maps or messaging.

Option A: Find local SIM shop

• Walk 20 minutes to airport SIM counter (closed at 11 PM)
• Wait until morning
• Take expensive taxi to hotel ($40 vs $10 Grab)
• Buy SIM next day ($10), wait for activation (2 hours)
• Total cost: $50 + 12 hours of frustration

Option B: Buy eSIM instantly

• Connect to airport WiFi
• Choose a current destination plan only after checking coverage, device compatibility, validity, and checkout price
• Follow the delivery and installation instructions supplied with the plan
• Install while connected to reliable Wi-Fi, then select the eSIM as the mobile-data line
• Test a webpage with Wi-Fi turned off before leaving the airport or hotel
• Cost and activation time: They vary by plan, provider, destination network, and device

What an eSIM can and cannot fix:

• It removes physical tray, contact, and card-wear problems.
• It does not fix poor coverage, an account hold, a carrier lock, or unsupported radio bands.
• Activation time and APN behavior depend on the provider and destination network.
• Most consumer eSIM profiles are installed on one device at a time; check the provider’s transfer policy before deleting or moving one.

Payment Options While Traveling

Payment methods and issuer approval can vary by country and checkout. Review the currently displayed currency, taxes, plan terms, and supported payment methods before purchasing; no payment method guarantees approval or bypasses provider requirements.

Check the Current Refund Terms Before Purchase

The promotion previously described here expired on December 31, 2025. Review BitJoy’s current refund policy and contact options before buying. Eligibility may depend on whether an eSIM was installed, activated, or used.

Exploring eSIM as a Reliable Alternative

What is eSIM & How It Works

An eSIM is a digital SIM embedded in your phone. Activation involves scanning a QR code from your provider’s app or email - no physical card needed.

Benefits Over Physical SIM

• Digital installation; activation time varies by provider and network
• No wear/dust in SIM slot
• Can store multiple profiles on supported devices; active-line limits vary

Example – BitJoy Global eSIM Solutions

BitJoy publishes destination-specific eSIM plans. Check the current coverage, supported network, plan validity, device compatibility, price, and support options shown for the plan before purchase.

Transition From Physical SIM Smoothly

Backup your current APN settings, ensure eSIM compatibility, start with a small plan to test.

Preventing SIM Connectivity Problems in the Future

Regular Updates

Keep your OS and carrier configs current.

SIM Care

Store in a sleeve when not in use, avoid bending.

Save APN Settings

Screenshot them for quick restore.

Use Wide Coverage Carriers

Select providers known for stable service in multiple regions.

1. Why is my SIM showing "Network Active" but I have no internet?

Most common causes (in order):

1. Mobile-data or APN configuration issue → Confirm the default data line and use the carrier’s official APN guidance
2. Incomplete activation → Follow the carrier’s stated activation window or contact support
3. No active data allowance or an account hold → Check the account and plan
4. Unsupported or unstable network mode → Use an available carrier-supported mode
5. Carrier network issue → Check the carrier’s official status page

Quick fix: Try Steps 1, 3, and 4 from the checklist above, then retest calls, texts, and data separately.

2. How do I get the correct APN settings for my carrier?

3 ways to find it:

Method 1: Carrier app

• Use the carrier’s official support site or app; avoid copying APN values from an unverified forum
• Match the instructions to your exact plan, device, and operating system

Method 2: Carrier website

• Visit your carrier's support page
• Look for "Device Settings" or "Network Configuration"

Method 3: Text carrier support

• Send text to carrier shortcode
• If the carrier publishes a setup code, use only the current code shown on its official support page
• Carrier codes and menu paths can change
• Contact carrier support when the official instructions do not match your device

Common input mistakes:

• Extra spaces before/after text ("vzwinternet " vs "vzwinternet")
• Wrong capitalization (some carriers are case-sensitive)
• Old APN from previous carrier still saved

3. Can a physically damaged SIM still show "Network Active"?

Yes! SIM can register but fail to pass data if gold contacts are scratched or dirty.

How this happens:

• Registration = simple identity broadcast (low data)
• Calls/data = continuous high-speed communication (needs perfect contact)

Check your SIM under bright light:

• Good: Shiny gold contacts, no scratches
• Marginal: Slight discoloration, may work intermittently
• Bad: Deep scratches, bent, visible wear

Test: Clean SIM with dry microfiber cloth, reinsert. If still fails → request replacement.

Tip: There is no dependable fixed lifespan for a SIM. Replace it if the carrier confirms it is faulty, its contacts are damaged, or it repeatedly fails in more than one compatible device.

4. How long does SIM activation take?

There is no universal activation time. A new line, replacement SIM, number port, eSIM, and roaming activation can each follow a different process. Use the deadline in the carrier’s confirmation message. If that time passes, contact the carrier and ask whether voice, SMS, and data are all provisioned.

5. Will switching to eSIM fix my repeated SIM problems?

An eSIM can help if the problem is:

• Physical slot damage (dust, bent pins, loose tray)
• Frequent SIM card wear from swapping
• Lost/damaged SIM cards while traveling
• Physical tray or card problems when the device and provider support eSIM

An eSIM will not fix:

• Carrier network coverage problems (eSIM uses same towers)
• Account/billing issues (problem is carrier-side, not SIM type)
• Device hardware failure (antenna, motherboard)

eSIM advantages for travelers:

• Avoids physical tray and card-contact failures
• Uses digital provisioning, with activation time set by the provider and network
• Multi-country coverage when the selected plan explicitly includes those countries and networks
• No swapping = no dust, bent pins, or lost SIMs

6. My SIM worked fine until I updated iOS/Android. What happened?

An OS update may refresh or change:

• Carrier settings bundle
• APN configuration
• Network mode preferences

Fix for iOS:

1. Settings → General → About
2. Wait 10 seconds-"Carrier Settings Update" prompt should appear
3. Tap "Update"
4. If no prompt appears → Reset Network Settings

Fix for Android:

1. Settings → About Phone → System Updates
2. Check for "Carrier Config" or "PRL Update"
3. If not available → Reset APN to default
4. Restart phone

After a major OS update, check for a carrier-settings update and restart if service changes.

7. Does cleaning my SIM card actually help?

It can help when dirt or poor contact is the cause, but it will not repair activation, coverage, account, or carrier-side problems.

When cleaning helps:

• SIM fails intermittently (works sometimes, not others)
• You see visible dust/dirt on gold contacts
• SIM has been exposed to moisture

How to clean safely:

• DO: Use dry microfiber cloth or cotton swab
• DO: Gently wipe gold contacts (not the chip)
• DON'T: Use water, alcohol, or any liquid (damages chip)
• DON'T: Scratch contacts with fingernails or sharp objects

When cleaning won't help:

• SIM never worked (activation issue, not dirt)
• Deep scratches or bent contacts (needs replacement)
• Phone doesn't detect any SIM (slot reader problem)

8. Why does my SIM work with WiFi but not mobile data?

Short answer: APN settings are one possibility. Also check the default data line, mobile-data toggle, data allowance, roaming setting, outage status, and carrier provisioning.

Why this matters:

• WiFi doesn't need APN to route data
• Mobile data REQUIRES correct APN to connect to carrier's data gateway
• Even one wrong character blocks all mobile data

Fix:

1. Reset APN to default (see Step 4 in Quick Fix Checklist)
2. Restart phone
3. Turn WiFi OFF to force mobile data test
4. Open browser and load website

Still not working? Call carrier and say: "My mobile data isn't working but WiFi is fine. Can you verify my APN and data provisioning?"

9. Can I use eSIM if my physical SIM slot is broken?

Usually, if the device supports eSIM and the carrier or travel provider supports that exact model. An eSIM bypasses the tray, but not antenna or motherboard faults.

Requirements:

• Device supports eSIM (iPhone XS+, Google Pixel 3+, Samsung S20+, many iPads)
• Check: Settings → About → look for "Digital SIM" or "eSIM" section

How to activate eSIM with broken physical slot:

1. Choose a current plan after checking coverage, device compatibility, validity, and checkout price
2. Receive QR code via email
3. Connect to WiFi
4. Settings → Cellular → Add eSIM → Scan QR code
5. Activation time varies; test with Wi-Fi off after the provider confirms installation

Avoids:

• Expensive repair ($50-150)
• Days without phone service
• Buying temporary burner phone

Many travelers keep eSIM as backup even after SIM slot repair-just in case!

10. What's the difference between "No Service" and "Network Active but not working"?

"No Service" / "Searching":

• Means: Phone can't find ANY cell towers
• Causes: Airplane mode ON, SIM not inserted, out of coverage area, antenna damage
• Fix: Check basics first (Airplane mode, SIM present, in coverage area)

"Network Active" / Signal bars visible but no calls/data:

• Means: Phone found towers and registered, but authorization failed
• Causes: Activation incomplete, wrong APN, account issues, network mode mismatch
• Fix: Follow Quick Fix Checklist in this guide

Think of it like:

• "No Service" = Can't find any airport
• "Network Active" = Found airport but boarding pass invalid

11. Will a factory reset fix my SIM problem?

A factory reset is a last resort and usually will not fix a damaged SIM, carrier outage, account hold, incomplete provisioning, carrier lock, or broken antenna. First update the phone, test the SIM in another compatible device, and use Reset Network Settings after backing up Wi-Fi passwords. Back up the phone and follow the manufacturer’s instructions before considering a full reset.

12. I’m traveling tomorrow and my SIM just failed. What is the quickest safe option?

While connected to trusted Wi-Fi, confirm the outage or account status with your carrier. If the physical tray is the problem and your exact device supports eSIM, compare a current destination plan’s coverage, validity, data allowance, refund terms, and activation instructions. Keep the existing SIM installed if you need it for SMS and the device supports dual SIM, then test the eSIM with Wi-Fi turned off before departure.
