Internet disappears after a call: check the selected line
On a phone with a home line and a travel eSIM, data may work differently during a call than before it. Capabilities depend on the device, settings and carriers' conditions.
Key points
- Devices do not all handle data in the same way during a call on another line.
- Consider your home carrier's conditions before enabling data switching.
Record when the problem occurs
Note whether the problem began during a regular mobile call and whether the connection returned afterwards. Check the selected data line. This symptom differs from a constant lack of internet and is useful when asking for help.
Find your model's instructions
Read the official description of how multiple lines work on your particular phone. Simultaneous calls and data, as well as automatic switching, may depend on the model and carrier. Advice for a different device does not confirm that the same feature is available on yours.
Consider the effects of a change
If the instructions suggest allowing data switching, first find out whether the home line could be used and how it would be charged. Do not enable the setting automatically just for one call. After the call, check the app you need and confirm which line is providing internet.
Check the relationship between calls and data using instructions for your specific device. Weigh the convenience of switching against each line's conditions.
