Why are my iPhone SMS’s not working? Could be due to a problem with your message centre number. Unlike most other phones this setting cannot be found in your iPhone settings.
To see what your current message centre number is, punch in: *#5005*7672# on your keypad to see what your existing message number is set at. If this is the incorrect number do the following, punch in: *5005*7672*SMSCNUMBER# insert the correct message centre number in place of ”SMSCNUMBER”. Punch in *#5005*7672# again to check if your message centre number has been updated.
