Contact the Mfr of the phone for help and support information regarding there product. 

Netgear has set up a community forum specifically for the Mobile Router products. Most of the people who watch that forum are more likely to have experience with mobile routers and know how to work it better than those of us who follow this router forum. Might be more likely to find someone who has a solution if the question is posted there:
