How do I check how much data I have left?
Your account shows the usage next to each eSIM. The operator reports it with a delay, sometimes of several hours.
In your account, next to each eSIM: we show how much of the plan is left and until when it is valid. The operator reports usage with a delay, sometimes every few hours, so the figure can lag a little behind reality.
Your phone counts usage too: on an iPhone in Settings › Mobile Service, next to the eSIM line; on Android in the network settings under “Data usage”. These counters are up to date, but they count from a moment you set, not from the start of the plan.
