can someone please let me know if i buy the tmobile sim and get one of those sim upsizer holders if it will work for internet in a dell latitude laptop that has a normal size sim holder under the battery? this sounds too good to be true, for £5 i get a sim and free mobile broadband for ayear do i need to pay the £10 top up or is that only for phone calls? i think i might need to run a program on the laptop to make it connect but not sure really.
