What network is your phone on?
There's many networks out there and it's a constant battle between these mobile phone companies. There's so much money in the mobile industry and there's much phone products available one of which being the network your on.

My favourite
There's so many networks as stated above. In my opinion my favourite network is Orange even though I'm on Vodafone. I've owned a phone in the past under the Orange network and it's perfect. There's much to Orange and there deals are really good and eye catching, A really good network that I recommend to anyone looking for a good network.
