Hi I am thinking about purchasing an iphone 4 sim free from Apple. However at the moment I have normal sized sim card. I am concerned that if I end up sending the i phone 4 back for whatever reason then I will be left with a micro sim and I won't be able to use it in any other phone and as a result I will have to pay my service provider £10 to get a new sim! Does anyone know if T-mobile can transfer your account details from a micro sim to an unused, normal sized T-mobile pay as you go sim, as I have some of them lying about?

Thanks in advance.

I know for certain that O2 will do it - so it is possible.
Whether T-Mobile are quite so helpful is another matter.
The only way is to ask them?

How about a MicroSIM adaptor? http://www.supergets.co.uk/?p=product&pid=2497

Some O2 shops will give you one free if you ask them nicely - not sure about other networks.

Nice idea.
