re new sim card just been sent
I received email saying I could change my sim deal to a cheaper one. £7 for 40g data. I am already with Id, so just thought it would be a case of keeping my number, only more data for a cheaper price. I've had an email saying there is a new sim in the post, with a different telephone number, and a new dd set up. I thought it would be a case of just changing my sim plan. I want to keep my present number. Do I need a new PAC number from id to keep my number when the new sim card arrives? Also do i cancel the dd for my old plan of £8? Thank you
