Purple.ai via 4g Routers?

Hi,

Has anyone set up purple.ai through 4g?

We have a fleet of cars with 4G routers and would love to use this.

What i am thinking is my solution is a Wireless Access point that can connect to a hidden SSID and Broadcast another SSID that has this enabled.

We are using Teltonika Rut850 because it has GPS tracking, but it does not feature a category cable to link to an access point that can use purple.ai.

If not, i am looking to Facebook Wifi, if someone has a solution for that.
