GSM Module

I have an FreePBX 60 with an ISDN card
I want to use a 4G sim card for outgoing calls because my mobile network provider offered me a very good rates.

Does Sangoma has GSM module ?

and how does this work ?
i create a trunk for the GSM module and then selecte it in the outbound route ?

GSM is being retired! Do you mean a 3G, 4G, or 5G device?

Most people use SIP based gateways for this.
