Why Connect to the Internet via Cellphone?
There are several reasons why you might want to connect to the Internet via a cellphone on Debian 12. For example, you might be traveling and not have access to a Wi-Fi network. Or, you might want to use your cellphone as a backup connection in case your primary Internet connection goes down.
Prerequisites
Before you begin, you will need the following:
- A cellphone with a data plan
- A USB cable to connect the cellphone to your Debian 12 computer
Connecting to the Internet via Cellphone
To connect to the Internet via your cellphone on Debian 12, follow these steps:
- Connect your cellphone to your Debian 12 computer using the USB cable.
- Open a terminal window on your Debian 12 computer.
- Enter the following command to install the necessary packages:
sudo apt-get install usb-modeswitch ppp
This will install the usb-modeswitch and ppp packages, which are necessary for connecting to the Internet via a cellphone.
- Next, you will need to configure the
pppdaemon to use your cellphone as the Internet connection. To do this, create a new file called/etc/ppp/peers/cellphoneand add the following contents:
/dev/ttyUSB0
115200
crtscts
noipdefault
defaultroute
usepeerdns
novj
noauth
connect "/usr/sbin/chat -v -f /etc/chatscripts/cellphone"
This configuration tells the ppp daemon to use the first USB serial device (/dev/ttyUSB0) at a baud rate of 115200. It also specifies that the connection should use the crtscts hardware flow control option and obtain an IP address via DHCP. The defaultroute and usepeerdns options tell the ppp daemon to set the default route and DNS servers provided by the cellphone.
- Next, create the
/etc/chatscripts/cellphonefile and add the following contents:
ABORT "NO CARRIER"
ABORT "NO DIALTONE"
ABORT "ERROR"
ABORT "NO DIAL TONE"
ABORT "BUSY"
ABORT "USERNAME"
ABORT "PASSWORD"
TIMEOUT 12
"" "AT"
OK "AT+CGDCONT=1,\"IP\",\"apn\""
OK "ATD*99#"
CONNECT ""
This script tells the chat utility to dial the cellphone's modem and connect to the Internet using the specified APN (access point name). Replace "apn" with the APN provided by your cellphone carrier.
- Finally, start the
pppdaemon using the following command:
sudo pon cellphone
This will start the ppp daemon and connect to the Internet via your cellphone. You can check the status of the connection using the ifconfig command:
ifconfig ppp0
