Hi Friends! I have purchased Sierra Wireless MC8780 3G/HSDPA 7.2Mbps/GPS WWAN Card from ebay and installed in my Lenovo s10 3t. I bypassed bios whitelist by flashing a bios mod downloaded from this site. The card was detected and after installing the 3G watcher, I could not connect to internet using my 2G sim (AirTel). When I changed my simcard from airtel 2G to BSNL 3G, It is working fine. Is there any way to use my 2G sim with this card? Please help...!
