I am proceeding with testing the Z3C, and so far it has been great.
However, I cannot find any way of taking the Z3C on the train and using the on-board WiFi. Sometimes the LTE coverage is very patchy and the train WiFi is more robust than the LTE service.
Is it feasible to look forward to being able to attach the Z3 to a public hotspot?
This appears to be an overlooked or even an undocumented capability.
Is there a USB cludge-around to connect to a mobile phone and use the phone's connection to the public WiFi service?
