Your new phone is available for use not

Bought a new contract from T mobile last tuesday. Good deal so I'm quite happy but although they gave it to me to take away last tuesday it was a week for the pac to be sorted and only today was I able to really use it. They charged me for the last 8 days on the bill I received today. Rang to complain (only 20 minutes on hold) and was told it was technically operational soon as I'd taken it out of the shop. The fact that no-one knew the number (a new one until old number poorted across) or that it didn't have any of my regular numbers stuck on my old sim card on it was irrelevant - I could if I tried hard make and receive calls. Told them it was poor service and invited them to waive the (very small) charge they had levied but they wouldn't.

It is quite normal for it to take about 7 days from when you give your PAC code to your new network for your old number to transfer across, when you connect (in your case last Tuesday) you are given a temporary number which you can use straight away to make and receive calls, you can find out what it is by calling another mobile or looking for My numbers in contacts if you have Nokia phone.
You can put your old sim into your new phone if you have got one and copy all the numbers from the sim to the phone and then put your new sim back into the phone and then copy all the numbers from the phone to the sim.
