Using & Managing eSIMs
How can I receive SMS and calls while connected with my data-only eSIM?
Last updated: 2026-09-03
Quick answer
Keep your home SIM in the phone and switched on. It continues to receive calls and SMS on your usual number, while the eSIM handles data. The two lines run side by side.
How to set this up
- Leave your home line enabled in your device's SIM settings.
- Set the eSiMAZE line as the line for mobile data.
- Turn mobile data off for the home line so it cannot be used for browsing.
- Set your home line as the default for voice and messages.
Why this matters for verification codes
Banks, airlines, and other services often send one-time codes by SMS to your registered number. Those arrive on your home line, so keep it switched on even though you are using the eSIM for data. If you remove or disable that SIM, those codes will not reach you.
What it costs
Receiving calls and texts while abroad is charged by your home operator under its roaming terms. Check its rates before you travel - eSiMAZE does not control or bill for that line.
Important
Disabling data on your home SIM does not disable calls and SMS. Those are separate settings, so you can keep the number reachable without risking data roaming charges.
