Currently with three and contract due to run out. I have recently updated my smartphone, so don't need a 2 yr contract or anything of that sort. Having done a bit of research with Dr Google and Prof Wiki, it would seem giffgaff is an alternative. However there seems to be a lot of dissent amongst the ranks along with increasing popularity and thereby problems.
The other thing is that i would like at least 1500mins and when you compare the giffgaff sim with a three sim only plan, they are both £25 and the three sim gives you a 500 mins more. Plus you have someone at the end of a tel no to call if things go tits up. So far three has been impressive in terms of coverage, connectivity, download speeds and service. Giffgaff is an unknown and seems less value for money at my talktime price point.
My friends however swear by the gaff and want me to switch. I am less sure. I remember reading someone on here has used gg? Any opinions?
