Public IP address for Mobile 4G - option GPTEXB3



I am using 4G usb modem (connected via a Dovado Pro router) in our office as it is the only decent speed broadband available. I need to acquire a public IP address (dynamic is OK) for port forwarding to internal services.


Currently we are using the APN: telstra.internet with gives a 10.x.x.x (internal address) which is not suitable for port forwarding.


From "internet research" AKA Google, I have learnt that ringing Telstra and asking for a code "GPTEXB3" to be added to the devices SIM service, we can then use APN: telstra.extranet - which will assign a dynamic public IP address.


Can anyone confirm if this is still the case, and if so, a number that I can ring Telstra (from a non-Telstra service), as we do not have any Telstra phone services - only data.


I believe my device is a ZTE MF821


Thanks in advance.
