Welcome to the OsmocomBB project

Introduction

OsmocomBB is an Free Software / Open Source GSM Baseband software implementation. It intends to completely replace the need for a proprietary GSM baseband software, such as

  • drivers for the GSM analog and digital baseband (integrated and external) peripherals
  • the GSM phone-side protocol stack, from layer 1 up to layer 3

In short: By using OsmocomBB on a compatible phone, you are able to make and receive phone calls, send and receive SMS, etc. based on Free Software only.

For more information please have a look at the ProjectRationale.

Working with OsmocomBB can be challenging (technically and socially). If you haven't done so already, please have a look at our requirements page.
