Five minutes at home. Online when you land.

Install your eSIM on wi-fi, ideally the day before you fly. Installing doesn't start your plan.

Before you start

iPhone

Install it at home

  1. Open Settings › Mobile Service › Add eSIM.On some iPhones it's called Mobile Data or Cellular instead of Mobile Service.
  2. Tap Use QR Code and scan the code in your email.Or tap Enter Details Manually and type the SM-DP+ address and activation code.
  3. Name the new line Tetherd when asked.It makes it easy to tell apart from your own SIM.
  4. Keep your own SIM as the main line for calls and texts.For mobile data, leave your own SIM selected for now. You'll switch when you land.
  5. Turn off Allow Mobile Data Switching.This stops your own SIM using data overseas and running up roaming charges.

When you land

  1. Go to Settings › Mobile Service › Tetherd and turn the line on.
  2. Turn on Data Roaming for the Tetherd line.It's needed for travel eSIMs, and it doesn't cost extra on Tetherd.
  3. Set Mobile Data to Tetherd.
  4. Turn off Data Roaming on your own SIM.Your own SIM can still receive calls and texts if your carrier allows it.
  5. No signal after a few minutes? Restart your phone.That fixes most first-connection hiccups. Still nothing? See the troubleshooting tips.
