Well its pretty simple question, so just mark the answer and if you don't see your carrier post it in the thread!
Good ole' ThreeUK. £12 a month for unlimited internet, 5000 texts and something like 200mins. I use my phones internet for everything, average month I use 200gb+ of data.
Because someone needs to say it, I personally use my pocket as a carrying device, thus a carrier for my cell phone.
that is an opinion, not fact. If you wanted to make it more factual, you could say, "at this point in time, at&t is the more preferred cell phone carrier"
My dad's work phone has AT&T, and it sucks... At least compared to the rest of the family's phones on Verizon. I don't have a preference, although I have used Verizon ever since I got my first phone. Never really had issues with it, and I get signal in even the oddest of places. Not really sure about prices though, lol.
