Unfortunately testing has beein inconclusive with newer GoToMyPC builds using mobile data for client connections.
We hope to have more information around this issue soon.
I have now had this issue of being unable to connect to GoToMyPc from 3G/4G connections for well over a year if not 18 months, and it STILL does not work. The service only works over Wifi. Can someone please advise what the problem and update on when it might be fixed. I know that Wifi is almost ubiquitous but there are still places and services (like paid for Wifi ) where GoToMyPc still does not work- please can someone help with this. We are using IPhones and IPads which work on Wifi and not on 3G/4G
