S-800 (LTE) devices have Qualcomm modems. Exynos devices have Motorola modems. The radio s/w you installed with the LTE ROM isn't compatible with your 3G radio. That's why it's borked.

hmm if the modem not compatible then why calling function is working ?

and there is no way to solve this problem ?

I have no idea why calling's working. The way to solve the problem is going back to a P-601 ROM. Throughout XDA they are posts from people that have borked their devices using Wi-Fi, 3G, or LTE ROMs interchangeably. They aren't interchangeable.

create a new access point without any proxy and port..
try any type of authentications type..
and in the Bearer you can see these options:
LTE
eHRPD
Unspecified..
this time try eHRPD... it should work
