SMS and a data-only package: what to expect
Mobile internet, ordinary SMS and calls are different services. Before buying, find out exactly what the package includes, especially if you expect messages on your usual number.
Key points
- A data-only package does not promise ordinary calls, SMS or a local number.
- The availability of your home number depends on its carrier and your device.
Read what the package includes
Look at the specific offer's description rather than just the word eSIM. If only data is listed, do not expect ordinary SMS and mobile calls through this line. If you need a local number, ask the seller about available options before ordering.
Check the home line
If you need messages on your existing number, ask your home carrier about the conditions for using it abroad. Check simultaneous line operation with the phone manufacturer. Selecting a travel eSIM for data does not cancel the home carrier's conditions for its other services.
Distinguish app messages
A messaging app can transmit messages over the internet, but that does not make them ordinary SMS. Logging into a service sometimes requires separate verification to a number. Check the method you need in advance and prepare permitted recovery options if the service provides them.
The package contents help you understand which tasks it solves. Plan internet for apps and access to your usual mobile number separately.
