Check this out. Not sure if your familiar with AT language, but it has to to with your access to the the GSM network. I think... MAybe someone could verify? :art:

  1. Check you have the right plan set up and make sure you have a compatible GSM sim card.

  2. Another ideal said thing to have is a 5v external power supply. 200mA to 300mA.

You can use AT commands directly by using this code or thread. You need the manual tho to follow along. ** double check you pin configuration from the GSM to the Arduino TX and RX ports. Also in the code**

AT commands DIRECTLY CODE

Hope that helps! Keep checkin. It is always something simple.
