One for the cognoscenti...
Now that the 21st. century is well established I have down graded to a gifted Alcatel *one touch* mobile phone! My grandchildren sport the latest i phones but this does all I need and has a good battery performance.
However, I have managed to corrupt the contact number for sending/replying to SMS messages. A *factory reset* has not fixed this.
I don't have a manual and the one offered on-line does not help.
Any suggestions?
