How do you rate the T-Mobile service?

Lauren of Flirtomatic posted a comment just now (thanks Lauren) saying that while she agrees that T-Mobile’s data service is excellent value, I failed to mention the appalling service.

Fair point.

However I haven’t found it that bad. I rarely use my mobile on the train because the signal quality is very poor. Is it a network-changing motivator? Not really. It’s good enough generally and I’ve only rarely got ‘network busy’ signals. But I don’t live in central London.

I worried about swapping to T-Mobile from the ultra good quality Vodafone but really, I haven’t bothered. I’m quite content. Especially given the huge margin of cost.

Any other T-Mobile users got feedback?
