New UK MVNO giffgaff have launched their “mutual giving” service, and while the real meat of the virtual carrier is in its system of rewarding helpful behaviour with free calltime, there are some appealing prices too for those obsessed with the bottom line. giffgaff – who use the O2 network – are offering a free SIM (presuming you top up with £10 straight away) and then £0.08 ($0.13) per minute calls and £0.04 ($0.07) SMS; calls in-between giffgaff SIMs are free, and data is also free until the MVNO can figure out a reasonable price plan.
You have to give HP and AT&T some credit: it takes guts to call your new smartphone
It comes as little surprise, given that we knew a release date
