So a few weeks ago I had to do a factory reset on my phone. Ever since it decides when it wants to connect to my network. ( Wi-Fi is fine. It's the mobile network that's the problem) while going through my settings to try and solve another issue, I noticed the "mobile network state" is "disconnected". Well, that explains it. But now how do I get it connected again? I've already tried resetting the apns and nothing happened. Help!And since I'm here. The problem I wax trying to fix when I came across the disconnected status is; I was trying to delete a file and it said something abt how my sdcard might be mounted as read only. How do I check this and if it is reach only, how do I make it not be?
