Not enough information.

What brand of mobile device? Did you check with the manufacturer?

Did you check your network settings as the error message suggested?

Does the device connect normally when not using your code? are other programs successful at using it?

If you did the above then post the relevant code so we can see what you are doing.

Thanks Arends for your reply
Its a Ericsson module with embedded device (model:HP hs2340 HSPA+ MobileBroadband). Yes when the device uses HP connection manager it connects successfully. As such the data provided from code is proper because same code works with other device like(huawei E173).

What network settings need to changed?

Thanks,
Chetan
