On your mobile interface you have an IP address starting with 10.xxx.xxx.xxx. This means that your IP is in the private IP address range, and is being NATed, and will not be reachable over the internet.
I'd recommend contacting your LTE carrier about the possibility to receive a public IP address. However, usually this is a paid service.
Alternatives include using RMS, or a VPN like ZeroTier, which does not require using a public IP on either end of the tunnel.
Let me know if you have any additional questions!
