Double NAT using 4g SIM

[L1TT1EAL]

Hi I'm currently using a 4g SIM in a router for home broadband and find I keep getting double nat when I'm on the xbox. I'm looking to upgrade to the unlimited max plan as it states mobile gaming so was wondering if that would solve my problem ?

Hey @L1TT1EAL 🙂 Are you currently using a Vodafone router or a third party router?

Are you using a data only SIM or a data & voice SIM? I have tried using a data & voice SIM and can't get port forwarding to work. Trying to get confirmation if port forwarding is supported on data & voice SIMs? I am not using a Vfe router but the port forwarding settings are very simple on the router so I think the issue is the network.
