This is for the moment you’ve landed, you’ve done the switch-on steps in Just landed? How to activate your eSIM, and the eSIM still hasn’t connected. Work through the steps in order; most people are online by step three. If your eSIM was working and then stopped, use My data stopped working mid-trip instead.
The app shows these same steps on your plan page, and they work offline.
1

Turn the Roamly line on

  • iPhone: Settings → Mobile (older iPhones say Mobile Service or Mobile Data; some regions say Cellular) → tap your Roamly line → Turn on this Line.
  • Android: Settings → Network & internet → SIMs → tap your Roamly SIM → Use this SIM. (Samsung: Settings → Connections → SIM manager.)
2

Select Roamly for mobile data

Your phone needs to be told which SIM to use for internet.
  • iPhone: Mobile → Mobile Data (the top row) → choose your Roamly line.
  • Android: on the SIMs screen, tap Mobile data and choose Roamly.
Only data switches over. If your normal SIM is still on, calls and texts stay with it.
3

Turn on Data Roaming for the Roamly line

This is the step people skip, because roaming sounds expensive. It isn’t here: your plan price is all you pay, and this switch just lets your phone use the local network.
  • iPhone: Mobile → your Roamly line → Data Roaming on.
  • Android: SIMs → your Roamly SIM → Roaming on. (Samsung: Settings → Connections → Mobile networks → Data roaming.)
Only turn it on for the Roamly line. Leave your home SIM’s roaming off so your home carrier can’t charge you. More in Data roaming: why it must be on.
4

Flick Airplane Mode on and off

Turn Airplane Mode on, wait ten seconds, turn it off. This makes the phone search for the local network again. Give it up to a minute.
5

Restart the phone

If Airplane Mode didn’t do it, a full restart usually does.
6

Pick a network by hand

Sometimes the phone latches onto a network your plan doesn’t work with. Your plan page lists the networks that do work, under Coverage & networks. Choose one of them manually: see Choose a network manually. Then flick Airplane Mode once more.

​
Connected but nothing loads?

If you have signal bars on the Roamly line but pages won’t open, check the APN settings, then confirm the plan hasn’t run out of data or days on your plan page.

Still offline?

Contact us and, to speed things up, send:
  • your phone model and the country you’re in,
  • a screenshot of your SIM settings showing both lines,
  • a screenshot of the Roamly line’s settings (so we can see Data Roaming and network selection),
  • a screenshot of your status bar.
If you can’t get online at all, hotel or café Wi-Fi is enough to message us.
