Connecting a Linux Computer to the Internet using a USB GSM Modem — Selective Intellect

In the previous post we had looked at how to use a ZTE MF190 USB GSM modem to
send and receive SMS using a Perl script. For this post, we will setup this USB
modem as an internet access point and connect to the mobile network with the SIM
card we purchased for the previous post. The mobile network is LycaMobile which
is an MVNO of the T-Mobile cellular network.

This post has been tested using the Beaglebone Black (BBB) we had setup in an
earlier post, so is a perfect example of how to prototype an IoT device that can
connect to the internet by itself using an external GSM modem. The same
instructions will be valid for a Raspberry Pi or any other computer that has a
USB A port and runs a Debian/Ubuntu variant of Linux.
