Has anyone succesfully been able to get the vjoycar T0026G to roam to AT&T 3g umts 2100mhz?
It latches on to t-mobile 2g and 3g just fine, It won't roam over to AT&T with the multi-network sim card I have. I'm curious if anyone else has any datapoints on this device.
North America? AT&T umts is band 2 & 5 in North America (1900 & 850 Mhz) USA. Have you tried Twilio super-sim?
