Relatively new tariff from Tesco Mobile which I think competes pretty well with the O2 Simplicity deal.
Free Sim Card
500 Free texts or 150 Free cross network Mins
You need to top up at least £15 a month, but apart from that there are no real catches.
You can also choose 3 fav numbers for half price calls and texts on top of this deal (not as good at T-Mobile MyFaves but I think that is contract only)
Reckon this is a good deal if you can unlock your phone and have a PAYG alternative working alongside it on the cheap.
