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.
