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...

➜  ~  sudo apt-get install -y gammu picocom

The best way to download a website for offline use, using wget

There are two ways - the first way is just one command run plainly in front of you; the second one runs in the background and in a different instance so you can get out of your ssh session and it will continue.

First make a folder to download the websites to and begin your downloading: (note if downloading www.SOME_WEBSITE.com, you will get a folder like this: /websitedl/www.SOME_WEBSITE.com/)
