I am in uruguay for a week, and to avoid roaming charges, i have a local sim (WITH BIS). i put it into my 9930, it says EDGE in capitals, CDMA US entries have disappeared from the HRT, replaced by GPRS UY. It only gives me BIS when I connect it to wifi. I have inserted the SIM into my 9700 and a local 8520, and it works fine.
how can i solve this?
