(C-x means ctrl+x, M-x means alt+x)

Prefix key

The default prefix is C-b. If you (or your muscle memory) prefer C-a, you need to add this to ~/.tmux.conf:

remap prefix to Control + a

SIM Card Management Over GSM Modem

A small guide on how to send and receive USSD codes on Linux

I am using the built in GSM (UMTS) modem of my Thinkpad X1 extensively because I am often in places with flaky internet connections. I connect through the standard Network Manager on Ubuntu and everything works fine. There was one major annoyance though. Every time I wanted to top up the SIM balance or book a new package, I needed a phone to send and receive USSD codes. So I took some time to figure out how to do it from the shell. I wrote this down as a help for others and a reminder for myself. Without further ado...

First intsall gammu and picocom.

➜  ~  sudo apt-get install -y gammu picocom
