Hi, I'm on Tesco mobile PAYG and have had my sim for nearly 7 years I want to keep my number and current arrangement however I'm getting a 3g capable phone from Amazon. I understand to connect to 3g I need a new sim, so if I get an new Tesco mobile PAYG sim and transfer my number using the PAC code will the credit also get transferred?

Thanks

You don't need a PAC , just contact Tesco and ask them to transfer your account (number, credit etc) to the new SIM.

Thanks, so I just need to order a new free sim and then call them, right?

You can just call them and tell them what you want to do.
