Here is what happens to a store under different circumstances.
Internet goes down and UE tablet connects to wifi - UE will not allow orders for that store as they can not see the tablet.
Internet goes down and the UE tablet connects via 4G - UE will allow orders and they will go to the tablet but will not go to POS and must be manually entered.
Internet goes down and is running on 4G and UE tablet connects to wifi * - UE will allow orders and they will go to the tablet but will not go to POS and must be manually entered.
Internet goes down and is running on 4G and using a VPN and UE tablet connects to wifi * - UE will allow orders and they will go to and show in POS.
Internet goes down and is running on 4G and using a VPN and UE tablet connects to 4G - UE will allow orders and they will go to and show in POS.
Internet working and UE tablet connects to wifi - UE will allow orders and they will go to and show in POS.
Internet working and UE tablet connects to 4G which is not working - UE will not allow orders for that store as they can not see the tablet.
The above are all the same if the store is using UE Integration or not so there is no advantage to stores having a 4G failover for UE Integration.
* This requires a 4G failover in the modem and not just connected to the server.
All 4G connections rely on the 4G signal to be strong enough. I recommend at least 2 out of 5 bars but the more the better. Having only 1 bar will not work reliably.
In Summary, Uber Eats Tablets require internet to have UE orders sent to it, POS requires working external access (port forward or VPN) for UE orders to be sent to POS
