What mobile phone network are you with?

In canada, I use Rogers

Giffgaff (if anyone wants to join giffgaff, I think you get a free £5 if you're referred by another member, so let me know if you want my referral link).
I used to be with O2 for years and years because I signed up to a great tariff while it was available for like a week. Then one day O2 sent me a text telling me they were 'upgrading' me to a worse tariff, so I stopped topping up.
Then I went to wales for a bit and needed internet access while I was there, so I thought I'd switch to giffgaff and use a bit of tethering, but I got there and realised there was absolutely no coverage for miles around, but I've stuck with them anyway, they're super cheap.

Tesco mobile, it's really good and I rarely have no signal. I was on orange for a while but they kept raising their prices so I moved across.

Because my whole family are on Tesco we get these perks so I went for 250mb extra data.

I'm with O2. I've been with the same provider since BT Cellnet, but only just :P O2 aren't as good as they used to be, and desperately need to boost coverage as even Three is being described as better in terms of signal coverage and network speeds. I would never swap as my loyalty means cheaper tariffs.

I'm on Virgin. I'm sure they use the masts of O2 and EE so the coverage is pretty good and I get mobile phone cover included at the same price as other service providers which was the main reason for me going with them.

I am with Bell when I am in Canada and Verizon when I'm at home.

I'm with an Irish network for Students called "48 Go Conquer". You can only get it when you're aged 18-22 and I think it's fab! All the packages are really cheap. For example I'm paying €10 a month for free calls and texts to all networks, 60 minutes to landline and 10GB of internet

Tesco Mobile hype.
