Hi!

I have an Android 2.1 tablet model MID-7CS, and I have the following problem. It's compatible with the Huawei USB 3G stick. When I connect the stick to the USB port and make the 3G enable in settings it connects to network (I can see the signal bars and when I enter the APN I can see the 3G logo as well) but no data transfer. I open the browser or email client it cannot make any connection.

I used NE Debugger to see what could happen and seems like after authentication the modem hangup immediately?? I copy the log here:

Any suggestion?
