tesco mobile triple your money - anyone use this, whats the catch?
i have an iphone payasugo with o2 but i want to move from o2 and use this tesco as a payasyou go, do i need to unlock my o2 iphone in order to use the tesco sim, also is it right that if you topup your tesco phone with £10 they make it £30? if so, whats the catch, seems too good a deal to be true? also can i keep my same number on this new tesco deal? or do i HAVE to get a new sim
