Hello and welcome!

Most ready-made boards do not expose the bluetooth pins, you might need one of the more “complete” ones, usually called “development boards” or “evaluation boards”. Also, the bluetooth functionality needs special firmware that you must request directly to SIMCOM, the manufacturer.

On a side note, the bluetooth implementation is quite old, I would suggest you to instead use any of the more modern chips with integrated bluetooth, like the esp32 by Espressiff (bluetooth 4.0 + BLE).
