My friend is currently on T-Mobile sim only 1 month rolling contract thing
He wants to get the N900 £30/month with T-Mobile from MPD

I'm not sure what the process here is since the transfer is going to be on the same network??
He wants to keep the old number so calling up T-Mobile to ask for PAC code to transfer number to..T-Mobile??

He's scared to call because:
1. He sounds stupid asking that question
2. They might convinced him to stay when asking to transfer number by doing the usual, offer better deal by lowering his current monthly payment
