How do I do that?
Also, just tried to phone some people and realised that all calls just end in a beep and dont connect!
What do you think is going on?
try checking signal
also try rebooting your phone take the sim out give it a wipe then turn the phone back on again
just for future reference for anyone else getting this error: I got it because the number I was trying to text had one digit too many
(have had the same happen for one digit too few, but in an area with barely any signal, so always just assumed that was why - took me months to catch on, cause I had the person's number in my phone twice, once correctly and once with one digit missing, hence why it took ages to catch on to)
