I am using a FP4 with self installed e/os for years now and had no problems so far.
But a few months back (Version 3.0.9 or something like that) my phone started loosing its connection to my cell services. Not just mobile data, the whole service endpoint is just gone and nowhere to be found in the network settings. I have to restart my device (sometimes multiple times) to get it to work again.
Next step would be to get a new sim card, but it doesnt feel like a hardware issue. Any help would be appreciated
I am having similar problem, although data is working. So when I don’t have WiFi, I can still use my browser etc.
However, if someone tries to call me, my phone doesn’t ring. Sometime later I get an sms from my provider that I have a missed call. When I try to call myself, I get a pop up that I a have no connection to the provider’s network. The only solution is to reboot the phone, and then I can call and receive calls again. I have no idea however for how long, as I don’t call a lot. After a while it just stops again. I also have the impression this must be a software Issue. FP4 on e/os 3.2
