The firs time I have been out of the country with my 6820. It has horrible reception, keep loosing the signal, I called ATTWS twice they gave me some kind of excuse that they have contract with one providor at 900mhz and another contract with another providor at 1800mhz. A friend of mine has a nokia 7210 and they have great reception.
This is not an International phone as advertized !!!!
