This guide walks you through esim setup Samsung Galaxy S23 from start to finish: checking compatibility, installing via QR code, activating mobile data, and managing dual SIM while traveling. Everything here is written from real setup experience on Galaxy S23 devices, using Samsung’s One UI menus exactly as you’ll see them. If you want a clean, stress‑free eSIM setup before your next flight, you’re in the right place.
Does Samsung Galaxy S23 Support eSIM?
Regional Exception: Galaxy S23 models purchased in China, Hong Kong, Taiwan, or Macao do not support eSIM, even though the same model elsewhere does. If you bought your phone in these regions, verify eSIM capability before purchasing a plan.
On all three models, you can:
-
Install multiple eSIM profiles
-
Use one eSIM + one physical SIM at the same time
-
Switch mobile data between SIMs in settings
How to quickly confirm eSIM support
On my Galaxy S23 Ultra, this took five seconds:
-
Open the Phone app
-
Dial
*#06# -
Look for an EID number
If you see an EID (Embedded Identity Document), your phone supports eSIM.
Important US carrier warning
Your Galaxy S23 must be unlocked.
Phones bought directly from US carriers (AT&T, Verizon, T‑Mobile) may be carrier‑locked, which blocks third‑party travel eSIMs. If your device only shows one network when manually selecting carriers, it’s likely locked.

What You Should Prepare Before Installing
Before starting the esim setup Samsung Galaxy S23, get these basics ready. This avoids 90% of setup issues.
Pre‑installation checklist
-
Stable Wi‑Fi connection
Required to download the eSIM profile. -
eSIM QR code or activation details
Usually sent by email after purchase. -
Unlocked Samsung Galaxy S23
Carrier‑locked devices will fail activation. -
Updated One UI software
Go to Settings → Software update. -
Keep your physical SIM installed (optional)
Useful for OTPs, bank messages, and calls from home.
Tip from experience: install your eSIM at home or at the hotel, not while rushing through airport security.
How to Install eSIM on Samsung Galaxy S23
Below are the exact steps as seen on Samsung One UI. Menu names are written exactly as they appear.
Method 1: QR Code Installation (Recommended)
This is the fastest and most reliable method.
-
Open Settings
-
Tap Connections
-
Select SIM Card Manager
-
Tap Add eSIM
-
Choose Scan QR code
-
Scan the QR code from your email
-
Confirm Download and wait for installation to finish
The profile usually installs in under one minute.
Important warning
-
eSIM QR codes are usually single‑use
-
Do not delete the eSIM after installation unless instructed
-
Deleting it often means you need a new QR code from the provider

Method 2: Manual Activation Code (Only if QR fails)
Use this only when the QR code cannot be scanned.
-
Go to Settings → Connections → SIM Card Manager
-
Tap Add eSIM
-
Select Enter activation code
-
Paste the SM‑DP+ address and activation code
-
Confirm and wait for installation
Manual setup works, but QR is always easier if available.
How to Activate eSIM for Mobile Data
Installing the eSIM doesn’t automatically mean you’re online. You still need to activate it correctly.
Activation steps
-
Go to Settings → Connections → SIM Card Manager
-
Toggle ON your new eSIM profile
-
Under Preferred SIMs, set:
-
Mobile data → your eSIM
-
-
Tap the eSIM → enable Data roaming
Why data roaming is required
Travel eSIMs work through international roaming, but here's what many travelers miss: when you enable data roaming on your eSIM line (not your physical SIM), you're activating the prepaid plan you already paid for-not triggering new charges.
Your home carrier (AT&T, Verizon, etc.) sees the eSIM as a completely separate line. For example, if you bought a 3GB eSIM for $8, that $8 is your total cost. No surprise bills from your home carrier.
Your eSIM data only starts counting after you land and connect to a local network-installing it at home on WiFi uses zero data.

How to Manage Dual SIM on Galaxy S23
One of the best parts of eSIM on Galaxy S23 is keeping your home SIM active.

Common eSIM Problems on Galaxy S23 & Fixes
“No Service” after installation
Likely cause: Data roaming is off or wrong SIM selected.
Fix:
-
Set eSIM as Mobile data SIM
-
Enable Data roaming
-
Toggle Airplane mode ON → OFF
eSIM installed but no internet
Likely cause: Network didn’t register properly.
Fix:
-
Restart the phone
-
Re‑enable the eSIM in SIM Card Manager
-
Wait 2–3 minutes after landing
QR code error
Likely cause: QR already used or expired.
Fix:
-
Check email for a newer QR
-
Try manual activation
-
Contact provider support if it still fails
Accidentally deleted eSIM
Reality check: Once deleted, your eSIM profile is permanently removed from your device-you cannot recover it locally.
Why this happens: eSIM QR codes are single-use for security. Once installed, the profile links to your device permanently.
What to do:
- Contact your provider immediately for a new QR code
- Most providers issue replacements, though some charge a reissue fee
- BitJoy's 24/7 support (email or WhatsApp) typically responds within 1 business hour
Prevention tip: After installation, screenshot your QR code email and save it securely. Label your eSIM clearly in SIM Card Manager (e.g., "BitJoy - Europe Trip") so you don't delete it by mistake.
Airport‑Proof Checklist Before You Fly
Do this once, and your Galaxy S23 will be ready the moment you land.
-
eSIM installed (but not deleted)
-
Data roaming enabled
-
eSIM selected for mobile data
-
Screenshot of QR email saved
-
Physical SIM still active for OTPs
This setup has saved us countless airport headaches.
Choosing an eSIM for Galaxy S23 Travel
When selecting an eSIM provider, prioritize these factors:
Device compatibility: Verify it works with Samsung Galaxy S23 specifically
Pricing transparency: Know exactly what you're paying-starting from $2.50/GB is competitive
Activation speed: Look for 2-5 minute activation, not "instant" claims that take 20+ minutes
Coverage: Check if one eSIM covers multiple countries (saves money on multi-country trips)
Support quality: 24/7 assistance matters when troubleshooting at airports
Risk-free testing: Providers offering refund guarantees let you test without commitment
BitJoy offers plans from $2.50/GB across 190+ countries, with QR code delivery that works seamlessly with Samsung's SIM Card Manager. Their 5-day money-back guarantee (valid through Dec 31, 2025) removes the risk of trying a new provider-if it doesn't work or you're unsatisfied, request a full refund via email or WhatsApp. For travelers who prefer crypto payments, BitJoy accepts Bitcoin, Ethereum, and USDT.
Conclusion

Most activation problems trace back to two mistakes: forgetting to enable data roaming or accidentally deleting the eSIM profile. Follow the steps above, install your eSIM before you fly, and you'll avoid both.
After your first successful setup, installing eSIMs for future trips takes under 2 minutes. That's how travel connectivity should work-invisible, instant, and stress-free.
Follow the steps above, prepare before you fly, and your esim setup Samsung Galaxy S23 will be smooth and stress‑free. Once you’ve done it once, setting up eSIM on future trips becomes second nature-exactly how travel connectivity should feel.
