I've recently been having an issue where my phone occasionally stops connecting to the O2 network, but doesn't seem to show me that's the case at all. I get no messages or symbols in the menu to say this is the case, so I have no idea it's happened until I try phone somebody, at which point I get a message saying "not registered to a network."
This means I've had my phone stuck in this state for a few days without noticing each time, and missed a few pretty important calls.
If I restart the phone, it starts workign again, and I will get a flood of text messages and missed call alerts, and am able to make phonecalls again. But it evenutally seems to go back to this state again and I again have no way to know until I try phone somebody again, which I don't naturally do very often.
I've just checked the network status for my area and got this result:
"Sorry, we're carrying out some upgrade work in this area.
We’re carrying out some upgrade work to launch 5G in this area. While we do this, you might have some trouble with your calls, texts and data but we're working as fast as we can to get things sorted."
Could this be the cause? Or is it more likely to be that my phone is no longer accepting my sim card properly?
