as it claimed to support 3G: WCDMA 850/2100 MHz.
It arrived today and I slipped in the SIM from my current Telecom connected mobile, and it all worked fine while I was in central Akl. When I got out west to Henderson it lost all connection. It appears that it must be connecting ok on 2100 but not on 850.
In service mode I found the band settings but I am not sure what is correct for this.

Anybody know where I can find the specific settings I need for Telecom usage, or will I have to switch to another provider?
