You are misguided, the ONLY way to tell if you are being NATed is if you compare the IP address that the device (a cell phone or the Mobly) reports as its WAN IP with the address from the "What is my IP" site.Your confidence is cute, but you are incorrect.
Go to a site like What Is My IP Address? IP Address Tools and More while using a phone or PC connected to the Internet through the Mobley. You will see a public IP listed. Mine is 107.77.83.xx. You can even go to ARIN or another whois site and look up who owns that IP to show that it is AT&T's IP that it has given to your Mobley. In this case it is AT&T:
That is your public IP. It is the IP your Mobley communicates with. Anything connected to the Mobley sits behind the internal router in the Mobley and has a 192.x.x.x address. Those IPs are not publicly routeable. The public IP on your Mobley is the same type of thing as the WAN IP on a DSL router or a cable modem. It identifies your WAN connection device to the Internet and gives it an address.
Similarly with your phone: When it is connected to the cell network (wifi off) it has a public IP. Once you turn wifi on and connect to a wifi network your phone takes on a local IP and the Internet-connected device is the WAN device connected to your wifi router.
As an example:
My phone (Motorola G4 Play on a Verizon Prepaid MNVO) gets an address in the 100.112.x.x range from the "status" page of the phone, ARIN says the following:
If I go to one of the sites which look up your outward facing IP, it returns an address in the 70.192.0.0/11 block which ARIN says is owned by Celco/VZW:https://whois.arin.net/rest/net/NET-100-64-0-0-1/ said:Net Range 100.64.0.0 - 100.127.255.255

As such, MY phone IS being assigned a non-public IP address that is being NATed before it hits the internet, but I would not know that by asking one of those sites what my IP is.
My wife's phone also gets an IP address in the 100.112.x.x range from the "status" page of the phone and a public IPV4 address in the 70.192.0.0/11 range when I hit one of those sites.
Now, is it a 1:1 NAT, or a 1:many NAT? Who knows, but neither of our phones is being assigned a publicly routable IPV4 address.
