Hmm, I bought an unlocked iPhone 4S. I was on Virgin Mobile for £15/month 200 minutes and 1gb internet with unlimited texts. I decided to go to GiffGaff for £10/month 250 mins unlimited texts and internet. I phoned up Virgin to get my PAC code and they offered me for £7.99/month 400 minutes, 5gb internet, 5000 texts. I'd never use over 5gb of data or 5000 texts so that's basically unlimited for me.
Only downside is that Virgin don't offer microsims so I'd have to get another sim made as I've already messed up my existing Virgin sim trying to cut it down lol. I already have a GiffGaff microsim.
What do you think I should do?
