With the quality of modern phones, it is data that is gonna kill you.(esp with tethering or the very handy Kies Air)
Giff Gaff (O2 netw) UL data, ULtexts, 250mins - £12 a month
24 month contracts are so long. On my last upgrade on vodafone, i could upgrade 6 months early, when i added those 6 months onto the 24 month contract it felt like the next time i could upgrade we would all be living on mars.
I'm out of contract in August ....gonna do the maths (buying own phone + sims...versus) but been reading about GiffGaff and many people rate it (kinda run by the users), plus no chance of 4g (on EE) where i am yet but O2 have 3g900 on our nearest masts
(that HTC One does look nice)
