How can I tell which eSIM is currently using mobile data?

To check which SIM is using mobile data:

• iOS: Go to Settings > Cellular. The SIM listed as Primary or Data is the one currently providing your mobile data.

• Android: Open Settings > Network & Internet > SIM cards. You’ll see which SIM is selected for mobile data.

If you have two SIMs active, one will be designated as the primary for data at any given time.
