I currently live between Spain (study) and the UK (usually returning to the UK for the holidays + summer). I;m currently on GiffGaff as my UK sim and just buy a £10 goodybag for the month that I'm back (auto-renew off) so I'm not paying for 2 contracts in 2 countries.
Only problem is GiffGaff's internet is so slow, its just unsuable (4G speeds are like 1-3mb pretty much throughout the day) so I want to switch to a different carrier.
Anyone know any way to do this apart from Pay as you go? I typically use 2-3GB for the month that I'm back.
