Right there danny!!

Giffgaff is a carrier that uses o2's network. Its the cheapest around, you use it pay as you go, plus on how much you spend you get cashback to use
Also they have a app if you ever need them, so instead of phoning say orange and on hold for 20mins, you send a message to a 'agent' and they get back to you with the solution
I know quite a few members who use giffgaff. Ive been on the £10 plan for 8 months now and that gives me 250 mins, unlimited texts and internet. You can upgrade to say £30 a month that gives you say 1k mins, unlimited texts and internet. If you want to downgrade next month or upgrade on how much your spending you can easily change it. Fully flexible.
Only bad content its hard to get the 'adult' settings moved over hahaa!! Only can bypass it if you use your WIFI
