Short answer: after installation, the plan usually starts when the eSIM first connects and uses mobile data at the destination.
If it does not work immediately
- Confirm the 4S eSIM label is selected for mobile data.
- Turn on data roaming.
- Restart your phone.
- Try LTE/4G.
- For Android, check APN.
