This dual-sim device has two sim cards installed. One is configured and selected for phone calls and
SMS and the second sim card is used for data/internet connection (mobile data). In fact because of roaming the first sim card can not even work for mobile data.
The problem: When I get a phone call (sim1) the mobile data channel (sim2) does not work for the time of the call (mobile data in the top bar disappears).
I assumed that this would work without issues (parallel usage).
So, does this actually work? Any experiences?
