eSIM vs roaming: which really costs less
Roaming outside your home region is billed per use and adds up fast. An eSIM is a prepaid data plan with a fixed price, so there is no surprise bill when you get home.
Fixed price upfront No bill afterwards Spend control Keep your number
Key differences
- Roaming: pay as you use, often without a clear cap.
- eSIM: prepaid bundle; data stops when used up until you top up.
- Roaming needs no setup; eSIM needs a compatible phone and a few minutes.
When roaming still makes sense
For a single day with almost no data use, or if your tariff already includes a roaming bundle. For anything longer, an eSIM is usually cheaper.
How to avoid a big bill
- Turn off data roaming on your home SIM
- Enable data roaming only on the eSIM line
- Track usage in the app
Does my phone support eSIM?
Dial *#06# on your phone. If you see an EID number next to the IMEI, your phone supports eSIM. The phone also must not be carrier-locked.
Supported devices include iPhone XR/XS and newer, Samsung Galaxy S20 and newer, Google Pixel 3 and newer, plus most recent Huawei, Xiaomi and Motorola models.
