I bought the same module because of price/availability reasons.

Do you have any datasheet available?

Did you make any progress?

Have you made any progress?

I am now coneccting the module but getting no response.

EDIT:

I successfully managed to get a response from the module using minicom.

The conections are:
- RPi TXD (physical 8) to SIM908 GPRS-RXD
- RPi RXD (physical 10) to SIM908 GPRS-TXD
- RPi 3.3v (physical 1) to SIM908 VCC_MCU
- RPi GND (physical 6) to SIM908 GND

After this you should follow this procedure:
https://electrosome.com/uart-raspberry-pi-python/

When you send a command, for example "AT" you will get an "OK" response.

Any doubts contact me.
