T-mobile... good for data.. carp for voice....
Im involved with running the company mobiles for my company... we have 415 of them out in the field... and i rekon about a 3rd of them have complained about coverage with T-mobile... seems to be especially bad down in the bristol/gloucester and surrounding areas..
T-mobile are trying to say to us its because we are using "old" phones.. (std issue is a nokia 3120) and they reccomend the 6230i... so basically they want us to replace 400-odd mobiles with hi-spec camera phones that cost twice as much for our monkey-sales force.. and it may or may not solve the problem
We have some WnW datacards too... theyre good with a strong signal, but the communication centre tends to lie about signal strenght.. anything below 4 bars and its uselss
