Mobile data connection breaks using only 1 SIM from Telia

I am experiencing the same problem, I have trouble using different apps and I have also realized that it is the mobile network that is malfunctioning. To solve the problem, I have to restart the phone. However, it’s very tiring…

Android 13

What additional information might be relevant to know for further investigation?

You gave more or less no Info. What is your set-up, SIM,eSIM, dual SIM? The provider? Does the workaround found by thr OP helps?

I have an eSIM (Telia) and I have the same problem as Jorg_Hohwiller, but I haven’t troubleshooted as extensively. The symptoms are the same, Chrome says I am offline and apps requiring data just keep spinning. What works for me is restarting the phone, I haven’t found any other way to get past the problem. Whether WiFi works or not, I haven’t had the chance to test, but I only experience the problem when I’m out in the city (without WiFi), for example when I need to start the apps for parking or retrieve entrance tickets for various events.

I would start checking the APN and maybe get in contact with the provider.
