BB with no BIS&BES , how to refix the data traffic
Please Login to Remove!
hi, I am in Chinese Mainland, and buy a BB 9780 in Hongkong. and now in our city, Shanghai, I use a WCDMA ISP server named Chinaunicom. But they do not provide BIS or BES serve. So the BB user here are always write some service books and lead those service books into BB. So a problem is coming:
We set APN as 3gnet or 3gwap, no username and password here, when we start-up BB, we can connect to internet normally, and if we get to another place after travelling for a long distance or getting to some dead point where the mobile phone could not search any signal, we will find that we can connect to Internet by the Browser of BB well but any third part APPs do fail. Those APPs are always show that we have no any effective data traffic.
so please could you tell us how to solve this problem, whether we could reset some parameters via engineering screens and force the data traffic reconnect automaticly after losing the signal?
