Eastwind Equipment Identity Register

A solution for access control and monitoring of mobile devices in the carrier’s network.

The platform controls and keeps accounting of subscriber devices registered in the operator’s network. Eastwind EIR uses the data received and configured logic to block network access for certain categories of mobile devices such as stolen, fake, or used for illegal purposes.

As well as helping to meet security requirements, Eastwind EIR allows operators to deploy new services to improve experience for their customers.
