Briefly looking = at plugins/sim900.c, I can see that only sim900 (not sim800) supports = gprs. Given that you get this far, I assume you hacked this part to = create gprs/gprs_context... The other place to look is to see whether the 'atmodem' gprs_context = driver is working properly. Perhaps you're missing the TUN/TAP support = in your kernel? Run 'sudo modprobe tun' and see if that fixes things. See drivers/atmodem/gprs-context.c for more details. Regards, -Denis --===============7443187212772716403==--
