Open Source Mobile Communications


The Osmocom (Open Source Mobile Communications) project is an open-source initiative focused on developing software for mobile communications. The Osmocom TAC (Type Allocation Code) database is a public resource providing information about mobile phone models based on their TAC. The TAC represents the first eight digits of a phone's International Mobile Equipment Identity (IMEI) number, a unique identifier assigned to each mobile phone.

Example topics covered:

  • TAC to brand mapping

  • TAC to model mapping

  • GSMArena brand and model links

Release Frequency

Ad Hoc - Osmocom updates as they receive updates from the community

As with all Public Domain datasets, Cybersyn aims to release data on Snowflake Marketplace as soon as the underlying source releases new data. We check periodically for changes to the underlying source and, upon detecting a change, propagate the data to Snowflake Marketplace immediately. See our release process for more details.


When available, GSMArena links for the model and brand are included. GSMArena.com is a website dedicated to mobile phone reviews, news, specs, and comparisons.

EAV Model: All Cybersyn products follow the EAV (entity, attributes, value) model with a unified schema. Entities are tangible objects (e.g. geography, company) that Cybersyn provides data on. All timeseries' dates and values that refer to the entity are included in a timeseries table. Descriptors of the timeseries are included in an attributes table. Data is joinable across all Cybersyn products that have a GEO_ID. Refer to Cybersyn Concepts for more details.
