Install & setup
How to install your eSIM on iPhone
Step-by-step iPhone install — from the email to full bars in about two minutes.
The quickest way is the install link in your FullBars email — on an iPhone it opens Apple's own setup screen directly, no QR scanning needed.
Option 1: the install link (easiest)
- Open your eSIM email on the iPhone you're installing on.
- Tap Install on iPhone.
- Apple's setup screen opens — tap Allow, then Continue through the prompts.
- When asked which line to use for Mobile Data, pick your new eSIM (only while you travel — see below).
Option 2: scan the QR code
If you opened the email on a different device (say, a laptop):
- On your iPhone, go to Settings → Mobile Service → Add eSIM.
- Tap Use QR Code and scan the code from your email or your FullBars account.
- Follow the prompts.
The two settings that matter
After installing, check these — they're the difference between full bars and nothing:
- Settings → Mobile Service → Mobile Data → set to your FullBars eSIM when you arrive.
- Tap your FullBars eSIM → Data Roaming → ON. Travel eSIMs need this on. It doesn't cost extra — you've already paid for the data.
Keep your normal SIM turned on for calls and texts if you like — your number and WhatsApp stay exactly as they are.
When to install
Install before you fly, while you've got decent wifi. The eSIM sits dormant until it connects to a network at your destination.
