The modem used in the GTA04 is the Option GTM601W, which is a
Quadband-GSM and Quadband-UMTS device.
For UMTS, it fully supports Bands 1 (which is 2100 MHz) and Band 5
(which is 850 MHz), so it should support both bands your provider
likely uses.
As there doesn't seem to be any official public information about the
device anymore, here's a link to a 3rd party detail list:
