I have a galaxy s5
recently the phone acted extremely weird when i first used it. So i flashed the phone and re-installed the android software which fixed all the weird problems i was having.
Now im still having 1 problem. with my SIM card installed i have full network (5 bars) when i try to make a phone call i get a "not registered on network" error. I remove my SIM card, the network is still present (5 bars)
I seem to have full signal at all times with or without my SIM card. The phone does not acknowledge the SIM when i put the SIM card in or when i remove it.
Did i do something wrong when i flashed my phone? i installed the same stock ROM that was on the phone with the proper carrier (videotron)
I need your help!
Thank you in advance.
