The number of IMSI-catchers (rogue cell towers) has been steadily increasing in use by hackers and governments around the world. Rogue cell towers, which can be as small as your home router, pose a large security risk to anyone with a phone. If in range, your phone will automatically connect to the rogue tower with no indication to you that anything has happened. At that point, your information passes through the rogue tower and can leak sensitive information about you and your device. Currently, there are no easy ways to protect your phone from connecting to a rogue tower (aside from some Android apps which are phone specific and require root access).
This project demonstrates how you can create a rogue cell tower detector using a Raspberry Pi and a SIM 900 module. The detector can identify rogue towers and triangulate their location. The demonstration uses a SIM 900 GSM module to fingerprint each cell tower and determine the signal strength of each tower relative to the detector.

Please note multiple researchers published and compiled this work. This is a list of their research in the 3G/4G/5G Cellular security space. This information is intended to consolidate the community's knowledge. Thank you, I plan on frequently updating this "Awesome Cellular Hacking" curated list with the most up to date exploits, blogs, research, and papers.
This wiki collects information about prepaid (or PAYG) mobile phone plans from all over the world. Not just any plans though, they must include good data rates, perfect for smartphone travellers, as well as tablet or mobile modem users.
An OpenWRT package repository for packages that have to do with using mobile broadband peripherals. Includes instructions for configuring the use of USB cell modems.
A company that makes lots of specialized shields and hats for the RasPi and Arduino. Antennae, cellular radios, IoT modules, sensors, feedlines, connectors, adapters, and kits.
This program show you IMSI numbers of cellphones around you.
How to create a portable GSM BTS which can be used either to create a private ( and vendor free! ) GSM network or for GSM active tapping/interception/hijacking … yes, with some (relatively) cheap electronic equipment you can basically build something very similar to what the governments are using from years to perform GSM interception.
vmdialer is a simple app that lets you operate a cellular modem (pre-paid or otherwise) from Virgin Mobile or Verizon on a Linux machine. The cell modem must be activated on a Windows machine before it'll function because the PROM has to be programmed with a special app, but once that's done you can use it with this app.
Note that the exact make and model is "Novatel Wireless MC760".
FrequencyCheck is a website that helps you determine if your current cellphone will work on the cellular networks of a particular country. You can either search for devices compatible with a particular carrier, or carriers compatible with a certain mobile device.
