Moved to the 9700 section.
T-Mo 9700 frequency
2G Network GSM 850 / 900 / 1800 / 1900
3G Network HSDPA 850 / 1900 / 2100
HSDPA 900 / 1700 / 2100
Singtel is GSM 900/1800. I did not see UTMS 2100 listed. But from what I see, I think it will be EDGE only, but I am not a frequency guru. Perhaps one will come along soon to give the correct information.
The device will need to be unlocked and the IMEI and PIN must be clear and not connected to a BIS/BES account. Before you buy a used BB, no matter where you get it, make sure you read this: http://www.blackberryfaq.com/index.p...Berry_off_eBay
