Connecting when you arrive

Turn the onesim line on for data and leave your home SIM for calls.

Turn the onesim line on

In your phone settings, open the onesim line and switch it on. Turn on data roaming for that line only.

Select onesim for mobile data

Set mobile data to the onesim line. Keep your usual SIM selected for calls and messages. Turn off data roaming on your home SIM to avoid roaming charges.

Give it a minute
