E750 v2 - How to activate roaming?

I have the E750 v2 with the EM060K-GL modem.
Does anyone know the AT commands for activating roaming on this modem please?
The AT+QCFG commands listed in the kinked post below give an error and Quectel does not have any additional information on their website…

Isn’t the roaming enabled by default?

I have just got back from my international travel and yes it does appear that it was enabled by default.
