In June of 2015, the GPRS+GPS module with chipset SIM908 is discontinued. The chosen chipset to replace it is the SIM928A. So the new version of GPRS+GPS uses the SIM928A. Those 2 chipsets are very similar: there are not any differences regarding GPRS features or handling. There are only small differences in GPS performance and handling.
There are 2 different GPRS modules, the GPRS+GPS module and the GPRS module (also know GPRS Pro module). The GPRS module offers GPRS connectivity. The GPRS+GPS module offers exactly the same GPRS features, and adds GPS features too. Both modules are controlled in the same way for the GPRS features: the software library is the same. This is the guide for the GPRS+GPS module. If you are not interested in adding GPS features to your GPRS module, you may consider the GPRS module.
