In chinaxxx65292;i can use CDMA 1X data plan and GPRS data plan both with local service provide.
just some tips:
1)to use CDMA, set cdma related parameters using Qpst
2)to use GPRS, just enter your web address in your browser like this:
http://xxx.xxx.xxx.xxx/?;WapGatewayAPN=your_apn;WapGatewayIP=
your_ip;WapGatewayPort=
your_port
doing so will activate the 8830's network connection ,gain your Ip address(use ##4357 ,you will see);
then you can use any internet related application as normal .
remember to replace your_apn/your_ip/your_port with your local parameters(ask your service provider)
