The message centre number got entered wrong on my new phone as i was in the process of writing a text during the time when they asked for it and I put in the wrong one. However now I cannot change the message centre number on the phone to the correct one. It keeps coming up with the message "Unable to change setting. Value read from SIM card". The number is fine on my old phone and I can text away with no issues. It is the new phone I have the problems with. Is there anything I can do to solve this problem or do I need to go into a vodafone shop?
