Install your ByeRoaming eSIM on iPhone over Wi‑Fi before you travel: open the ByeRoaming App (or your purchase email), choose QR install or iPhone quick install, then keep the travel line ready to enable when you land. You need an unlocked, eSIM-capable iPhone (typically iPhone XS or newer).
Install with QR code
- Connect to Wi‑Fi.
- Open Settings → Cellular (or Mobile Data).
- Tap Add eSIM / Add Cellular Plan.
- Choose Use QR Code and scan the code from the ByeRoaming App or email.
- Follow the prompts, label the plan (e.g. "Travel Data"), and leave your home line as default for calls if you want.
- Keep the travel eSIM installed; turn on Cellular Data for that line after you arrive.
Install with iPhone quick install (App)
- Open the ByeRoaming App on your iPhone while on Wi‑Fi.
- Open your purchased plan and choose the quick-install / one-tap install option when offered.
- Confirm the system eSIM install sheet, then label the plan.
- After landing, enable the travel eSIM for data and turn on Data Roaming for that line if prompted.
After install
Most ByeRoaming plans start the validity countdown on first connection to a local network — not at purchase. For Android steps see How to install an eSIM on Android. Destination examples: Japan eSIM. If install fails, see Why is my eSIM not working?.
