The Message Centre Number is responsible for the delivery of an SMS (text) message sent from a Mobile Service. If this number is not set correctly then the SMS will not be delivered to its destination. The Message Centre Number does not affect you receiving an SMS.
Text messaging should be ready to go on a Mobile service as soon as the phone is set-up. However, should you not be able to SEND an SMS but you can use all other services you may want to check that the Message Centre number is stored correctly.
Each Mobile Network holds it's own Message Centre, TalkTalk's is as below:
TalkTalk Mobile Message Centre Number +447785011324
Where the number is stored is dependent on the model of phone the customer is using. It's usually stored within your Message Settings menu.
