if you are asking how you send letters over a phone call... that is not possible... you can only send 1,2,3,4,5,6,7,8,9,0,*,# 😀 perhaps they just want you to press the number key with the letter on it? if this is the issue then you should contact O2 and ask them how to enter letters when prompted for a post code using the
IVR system.
my original post:
text entry changes depending on what function you are doing...
the letters on the keypad in the phone application are just there to help you dial numbers that are listed with letters instead of numbers... for example 800 BUY NOW3 or 866HOLIDAY
if you wish to send a text message press the home button at the bottom of the screen and select the "Messages" icon... if you don't see it slide left or right on the screen with one finger until you find the page it is on.
once your in messages you can create a new message and when you do so you will find the on screen keyboard changes to a alphabetic one to let you enter the messages. if you need other symbols and numbers on that keyboard press the "123" at the bottom.
