Since several weeks I have severe trouble with mobile data: It used to work fine for several years I do have SIM (Telekom) and eSIM (1&1) When the error occurs, I do not get mobile data connection anymore, I can switch the provider/SIM, I can reset network, I can change or reset APN, I spent days …

Already did. Thanks for the hint to once again check all settings. Again, curious how it’ll behave at higher speeds of transport since the network triangulation then is much more work for a phone…

I’m constantly loosing it the moment it (obviously) switches cell tower Can report that my “fix” only makes the issue less bad but still occuring during commuting. Got better in the sense that it did occur on the same ride approx 5times in 20min and now only 1-2 times.

Ok I can report that the issue still prevails with the latest update and it is also still very annoying while commuting/driving with higher speeds. My fix as described isn’t a fix but as already said makes it less frequent and thus a bit less annoying than before.

I tried to remove the physical and esim and then put everything back and set it up again. No changes. My bug seems definitely software related since nothing in terms of troubleshooting worked so far. Furthermore, prior to the mentioned Update that never occured. Very annoying bug.

The topic here is about the FP4 however you linked FP5 information (only applicable for Germany ) So not sure this is connected. @jamesmcstrid a few more details would be helpful

Can you please share your exact OS version? FP4.TP20.C.087.20231122 Android 13

[image] Volker: in case you use only one SIM (and eject the other one from the beginning), does the problem also happen (i.e. it happens on both SIMs configured from the start and with the other SIM not included)? Incredible. I switched of my eSIM and WiFi and using my Telekom SIM, I am now o…

Your OS version is up-to-date. That’s good. And great that you’ve found an “emergency workaround” for now. Maybe you’ll even need some more testing to get closer to the root of the problem… I suppose it’s time to contactsupport .

I have the exact same issue on my fp4. My provider is tele2. Did anyone manage to solve this?
