Ok, got my new curve but it is locked to tmobile and i have an 02 sim. It says that the postage will take 10-28 days to come through for the code to unlock it. So i decided to get a tmobile sim for a short period until the unlock code came.


I was wondering... If i use the tmobile sim for long enough will i still be able to use the 02 one after?

And after i ordered the tmobile sim it said this......Thanks for your order. We'll deliver your SIM as soon as possible, but it may take up to 7 days.
Activate SIMs when you get them by popping them into an unlocked phone and topping up £5 or more.

Does this mean i have to have a tmobile phone unlocked or does it just apply to non tmobile phones?

And last one, what settings will save to the sim? And if i register anything will that stay on the phone or go away when i change sims?

yes.
it applys to non t-mobile phones.

nothing.

Thank you
