No one can help you if you don't give precise information.
We don't know your phone's CID. We can't know what problem occurs if you just say "something is wrong with the network".
You always say "something is wrong", that doesn't get us anywhere.

Please tell us which version of XS++ you are using, pot the XS++ logs and describe PRECISELY what you do and what errors you get.

A good answer requires a good question...think about it ;)
