You would need to buy a GSM4 submodule to replace the (Siemens) submodule that you have. I dont know if we have a price for that yet but it should not too high

Next you need to put in the U2 EEPROM. Yours does not have an IC socket in the U2 position. If you are handy with a soldering iron you can solder in the 8 pin IC socket and get a U2 eeprom to plug in
