New pay monthly contract, wrong phone number.

[Anonymous]

Hi,
Two days ago I just move pay and go number to pay monthly. Today when I check my online account I just recognise on this account I have my old number which is not used from 4 years I think. On the account I have information it will be activate from 16.10.13 and on same day I will get new phone as well. I need to change that number to my actually number which everybody know and it is very important for work. I read some information about change number but they might charge £35. The question is... Can I change phone number before I will activate a new sim card? Or cancel buy and return?
Thanks for your help

When you get your new phone and sim card just use the Swap my sim form or text SWAP to 20220 and your present number will be transferred to the new sim card.

There is no charge for this.
