This device can apparently 'charge with internet' at home from my router, then allow me to connect with my phone while I'm out and about. It claims to work on planes and subway trains too.
In the FAQs they make reference to a SIM chip in the device, but this still wouldn't let it work on planes etc.
Have you seen those "Portable battery chargers for smartphones" ?
Well the idea of the device is based on it , but the difference here is the internet part.
Instead of charging the device from pc with electricity you will charge our device ( WiFiEX) with internet from your home-wifi.
To put it bluntly is there any way this could work both economically and technically, or is this a scam?
