Advise for a travelrouter

Yes, mine has EP06-E 3/4g module in it and works well. (Check out Amazon - other outlets are available!)

BTW, mine is installed in a Motorhome with an added Buck/Boost PSU which adds protection from spikes, and connected to Habitation Battery.

We roll up, log in to local WiFi using GL.inet Inerface/Web page (if needed) and allow connection to Mobile Network. All devices ‘just connect’ to Router. It also means we can get WiFi while travelling.

Not checked in Europe yet, but module is specced for EU.
