VS-GWM400 Module Registration denied

I have a VS-GWM400 firmware rev.2.4.6 and M35 gsm module frw.M35AR02A02.
The module remain in net req and registration denied,but the sim works correctly if inserted in another module or telephone.

Hello

What do you mean about insert the SIM card into other module? You can leave your skype here we can contact you ASAP.

hi.
I meant that it is not a problem of sim.
The sim works correctly in other slots or mobile phones.
