eSIM: What is eSIM and How Does it Work?

eSIM stands for embedded SIM, a digital solution that offers flexibility and convenience for mobile connectivity. Unlike traditional SIM cards, which must be physically swapped, an eSIM allows users to switch carriers and plans digitally. Here’s a closer look at what eSIM is and how it functions:

What is eSIM? It is a programmable SIM embedded within a device, eliminating the need for physical SIM cards. eSIMs can store multiple profiles, allowing users to switch between carriers easily.
How Does It Work? The eSIM operates through software. When you activate an eSIM profile, your device downloads this information securely from your carrier via the internet. Users can manage their mobile plans directly through their device settings without visiting a store.
Benefits of eSIM:
- Convenient for travelers who want to switch carriers without changing SIM cards.
- Allows for multiple plans on one device perfect for separating work and personal mobile data.
- More secure and less prone to loss or damage compared to traditional SIM cards.

Frequently Asked Questions: eSIM for iPhone 15

Got questions? Here are answers to the most common eSIM questions from iPhone 15 users.

General eSIM Questions

Q1: What exactly is an eSIM and how is it different from a regular SIM card?

A: An eSIM (embedded SIM) is a digital SIM card built directly into your iPhone 15's hardware. Here's the key difference:

Feature	Physical SIM Card	eSIM
Format	Plastic chip you insert	Digital profile downloaded
Installation	Insert into SIM tray	Scan QR code
Time to activate	15-30 minutes (find shop, buy, insert)	2-5 minutes (scan & activate)
Can lose it?	Yes - tiny plastic card	No - stored digitally
Switch carriers	Physically swap cards	Download new profile
Multiple numbers	Need multiple physical SIMs	Store 8+ profiles digitally
Size	Takes physical space	No physical space needed

For travelers: eSIM means no more hunting for SIM card shops at airports. Buy online before your trip ($2.50+), scan QR code, and you're connected when you land.

Q2: Does my iPhone 15 support eSIM?

A: Yes! ALL iPhone 15 models support eSIM:

iPhone 15
iPhone 15 Plus
iPhone 15 Pro
iPhone 15 Pro Max

BUT - The configuration varies by region:

🇺🇸 US/Puerto Rico models:

eSIM ONLY (no physical SIM tray at all)
Can use 2 eSIMs simultaneously
Model numbers: A2846, A3089, A3090, A3092

🇪🇺 Europe/International models:

Dual SIM (physical nano-SIM tray + eSIM)
Can use 1 physical + 1 eSIM OR 2 eSIMs
Most flexible option

🇨🇳 China mainland models:

Physical SIM ONLY (NO eSIM support)
Exception: iPhone Air (2026) - first eSIM-capable in China
Dual nano-SIM trays

How to check which you have: Settings > General > About > Model Number

Q3: Can I use both eSIM and a physical SIM card at the same time?

A: Depends on your iPhone 15 model:

YES - If you have European/International model:

Use 1 physical SIM + 1 eSIM active simultaneously
Example: Keep your T-Mobile physical SIM for calls, add Bitjoy eSIM for travel data
Perfect for travelers who want backup options

NO - If you have US model:

US iPhone 15 has NO physical SIM tray (eSIM-only design)
But you CAN use 2 eSIMs at once (Dual eSIM)
Example: Your regular carrier eSIM + Bitjoy travel eSIM

Common setup for travelers:

eSIM 1 (or physical SIM): Your home carrier (AT&T, T-Mobile, etc.)
- Use for: Phone calls, SMS, 2FA codes
- Data Roaming: OFF (avoid charges)
eSIM 2: Bitjoy travel eSIM
- Use for: Internet, Google Maps, WhatsApp
- Data Roaming: ON

Q4: How many eSIMs can I store on my iPhone 15?

A: iPhone 15 can store 8 or more eSIM profiles and use 2 simultaneously.

What this means:

Store 8+: You can have eSIMs for Thailand, Japan, Europe, USA, etc. all saved
Use 2 active: Only 2 can be "on" at the same time
Switch anytime: Toggle between stored eSIMs in Settings

When you travel to Europe next month:

Turn OFF Thailand eSIM
Turn ON Europe eSIM
Takes 2 seconds in Settings

Storage tip: Keep expired eSIMs if you'll return to that country. Just reactivate or buy top-up instead of full reinstall.

Q5: Will using an eSIM affect my regular phone number?

A: No! Your regular number stays completely active and separate.

How it works with Dual SIM:

Your Home SIM/eSIM (e.g., T-Mobile):

Still receives calls to your regular number
Still receives SMS and 2FA codes
Keeps your iMessage and FaceTime
Data Roaming should be OFF (to avoid expensive charges)

Your Travel eSIM (e.g., theBitJoy):

Provides cheap data for internet
Usually no voice calling (data only)
No SMS (most travel eSIMs are data-only)

Real example: You're in Bangkok with Bitjoy Thailand eSIM:

Your mom calls your US number → You receive call (free for you, she pays US rates)
Bank sends 2FA code → You receive SMS on US number
You need directions → Google Maps uses Bitjoy data (cheap)
You call Uber → WhatsApp call uses Bitjoy data (cheap)
Someone texts your US number → You receive on US number

Bottom line: Your regular number works exactly the same. The travel eSIM just provides cheap internet.

A: YES! In fact, we strongly recommend installing 1-2 days BEFORE your trip.

Why install early?

Plenty of time to fix issues

If something goes wrong, you can contact support
Not rushing at the airport with bad WiFi

Better WiFi at home
eSIM profile downloads faster on home WiFi
Airport WiFi is often slow/unreliable

Less stressful
One less thing to worry about while traveling
Know you're ready before you board

Test everything works
Confirm eSIM installed correctly
Check all settings configured properly

Don't worry about early activation:

eSIM will NOT activate (or start billing) until you land

Validity period starts from FIRST CONNECTION, not installation

Example timeline:

Tuesday-Thursday: eSIM sitting ready, not active
