I have a pay as you go andexpired in a couple of days with no limits. I can not get the 1st screen to open so that I can make calls or check my e-mail. I am locked out of the phone for any acivities at all
Some of the buttons on the phone would not work the other day 7-8-9, I guess they are on the same row that allows you to slide the phone to the open position and call and check messages. Some thing must be wrong with the phone .
A hard reset is basically wiping everything on the phone and setting it back to factory settings.
If physical buttons aren't working on the phone, a hard reset will probably not fix that though. Looks like a hardware issue with the phone, do you have insurance with your carrier? If not your phone manufacturer might have a warranty period.
