Amazing prices, coverage and internet speeds
I had reservations on joining GiffGaff that I'd be a 'second rate' customer on the 02 network (as warned by my vodafone customer retention agent..) This is not the case at all - I've always had great signal and internet speeds - enough to stream highest quality music in Spotify. I also haven't been affected by any outages as mentioned in other reviews. Their prices offer incredible value, and GiffGaff are very up front about where their costs are reduced; for example not having dedicated customer service teams in call centres. I'm saving £25 per month since leaving vodafone, and getting unlimited data; and if you know how to use your phone properly, and don't break the rules (ie. no tethering) I don't see how you could have a problem!
