My company have been offered a very good deal from T-Mobile UK under their Business One Tariff and are considering moving to them from Orange. I have had a few people mention that the signal coverage isn't as good with T-Mobile as the other networks - this concerns me a bit because we have a lot of field-based engineers roaming around the country so it is important for us to have good coverage. Does anyone have any opinion on whether this is likely to be a concern, I'd be particularly interested in hearing from business users who travel around quite a bit with a T-Mobile handset e.g. someone working in field-service or sales etc. We have also looked at O2 and Vodafone which are quite a bit more expensive (is it a case of you get what you pay for??).
We have found Orange to be reasonable although we have been having a few problems with the antenna local to our office and also some problems with call drop-outs recently.
Thanks for your help
