While not a receiver itself, it is the primary tool used to "read" the data once the GSM software has captured it. Kalibrate (Kal):

For those looking to explore this field, several open-source projects have become industry standards: While not a receiver itself, it is the
A tool used to find local GSM base stations by scanning for the strongest signal peaks. Security and Ethical Considerations Modern GSM networks use A5/1 or A5/3 encryption
It is impossible to discuss GSM data receivers without mentioning encryption. Modern GSM networks use A5/1 or A5/3 encryption to protect user privacy. Most consumer-grade receiver software can only "see" the encrypted headers or unencrypted broadcast information. Attempting to bypass these protections to read private messages or listen to calls is illegal in most jurisdictions without explicit authorization. Conclusion
Perhaps the most widely used toolkit today, it is based on the GNU Radio framework. it allows users to detect GSM blocks and decode the data in real-time. Wireshark:
