What is the GPRS module for?
GPRS module is a device to realize the modulation and demodulation of GPRS (packet switching) communication, which can be used to put the SIM card of China Mobile Unicom into the GPRS network or send and receive multimedia messages and short messages (at the same time, it needs software implementation).
You can insert the mobile phone card and connect the computer to dial up the Internet (but the GPRS network speed is too slow, so it is not necessary at this stage).
