networking 4g connection?

hello, i have set up my game for mobile, i have my own master server,facilitator,and proxy server running on my desktop, the one provided by unity, when devices are running through wifi, it works fine, but running through 4g the device cant register a host or poll the host list, i looked at the networking for mobile unity page and it says

Note: EDGE / 3G data connections go to sleep very quickly when no data is sent. Thus sometimes you may need to "wake-up" networking. Just make the WWW class connect to your site (and yield until it finishes) before making the Unity networking connection..

so what im wondering if that is the problem of why 4g wont connect and if someone can clarify how to go about getting it to work, thank you for your time
