I think it does but I hear coverage isn't great with 3 and I get around quite a bit so trying to stick with networks which use O2/Vodafones network, as I think they have best coverage ATM.
I'm on O2, and for about £42 a month I get an iPhone 5s with unlimited calls and texts and 1GB of data.
Also O2 have recently upgraded everyone with a 4G compatible phone from 3G to 4G free of charge, as long as you are in a covered area.
I'm on EE and pay £32 per month, for that i get unlimited mins and txt's and 2gb data allowance. As part of the tariff though i get Deezer free which is great as i use it all the time. I can also early upgrade after 6 months which is nice too. I was with Orange before upgrading and i'm loving EE so far. Their app is also great for managing my tariff or just checking my remaining data.
Like all the carriers it depends on where you are. My experience with EE is much better than I had with 3. I am in London.Does anyone know if EE has good network coverage?
Even if your not in a 4g area if you have a 4g sim card and a 4g phone you should receive a text offering the free 4g bolt on from o2.
