Teltonika RUT950 / RUT955 remote access with standard 3mobile SIM (UK) 

If you want to use your Teltonika RUT950 / RUT955 4G router for any application where you need to connect to the router over the internet and use service like Port Forwarding DDNS, but do not want to use a Fixed IP SIM Card, then in The UK you can get away with using a 3mobile data SIM and using the APN of 3internet to request a dedicated, public IP address from Three Mobile network - You do have to connect at 3G speeds and are not guaranteed to receive a public IP address which you can see happens in the video - but this will demonstrate how to configure the RUT950 APN setting and enable remote admin and how to check that your connection did in fact receive a dedicated, public IP address.
