Already installed your eSIM? When you arrive, check which line your phone uses for mobile data.

​
1. Check your plan

Make sure:
  • your current country is included in the package’s coverage;
  • the package is valid or ready to start;
  • you understand what starts its validity.
If the phone doesn’t connect immediately, don’t reinstall the eSIM.

​
2. Enable the installed eSIM

In your phone’s SIM settings, turn on the eSIM that belongs to this order. The line’s name on the device may differ from “2Chip”.

​
3. Select it for mobile data

Go to Settings → Cellular → Cellular Data (or Mobile Data) and select the installed travel eSIM.
If your phone supports automatic mobile-data switching, check that it won’t switch back to your home SIM unexpectedly.

​
4. Check data roaming

Some travel eSIMs need Data Roaming turned on because they connect through partner networks. Check the conditions of your package. Enable it for the travel eSIM, if required. You don’t need to enable roaming on your home SIM for 2Chip to work.

​
5. Let the phone choose a network

Leave network selection on Automatic first. If it doesn’t connect and 2Chip lists supported operators for your package, try one of those networks manually. Don’t select an arbitrary operator.

​
6. Only change APN when required

Normally APN is configured automatically. If your package provides manual APN details, enter exactly those values in your phone’s mobile network settings.

​
7. Test the connection

Turn off Wi-Fi and open a website:
  • Internet works: you’re connected.
  • No service: check the eSIM line and supported networks.
  • Signal but no data: check mobile-data selection, roaming and APN.
  • Very slow: check coverage and package limits.

Internet still not working?

Choose the symptom you see and follow the relevant checks.
