Raspberry Pi SIM868 PPP Dail-up Networking

SIM868 module features GPRS function (2G Network), so we could use SIM868 module to dial-up networking using PPP.

As we know, SIM868 module features GPRS function, however, it is controlled with AT instructions, and AT instruction is not convenient in Raspberry Pi. If the function could be operated just like operate WIFI it will be much better. In this case, we describe how to use PPP to dial-up networking.

Fistly, we need to install PPP server

sudo apt-get install ppp

Switch to root permission

sudo su

Enter the directory /etc/ppp/peers, copy the file provider and name it gprs

cd /etc/ppp/peers
cp provider gprs

Open file gprs and edit it

sudo nano gprs

Exeute the command as below to run it in the background

pppd call gprs &

Close the network

ifconfig eth0 down
ifconfig wlan0 down

route add -net 0.0.0.0 ppp0

Then execute command ifconfig you can find the ppp0

Finally, just try to ping one web site like google or baidu.com. If you can ping the web site successfully, it means that the setting is correct and it can network now.
