It's not looking very good for my relationship with T-Mobile.
On the face of it, there's nothing wrong with what you're getting with the tariff (no one has mentioned so far that you get a booster either), I won't use anywhere near 500 texts, and 600 minutes will just about do..But...
500Mb data allowance, and a phone cost of £269 for a 32Gb model (compared with the same data allowance and calling minutes on O2 with unlimited texts and a handset price of only £209), and the fact that T-Mobile is merging with my least favourite mobile network, Orange, and a drop in local signal quality over the last 6 months or so means that unless they are going to give me a 32Gb model completely free (unlikely, I know), I'll be jumping ship to O2 in January when my contract expires.
