Cellular Telephone Information for

Electric Metering Installations

As a result of the cell phone service providers’ network changes, currently used cellular equipment will need to be changed.  Consumers Energy is testing possible solutions for compatibility with our systems.  Once testing is complete, additional specifications will be communicated.  In the meantime, we encourage you to NOT purchase any additional cell phones for use in telecommunication to Consumers Energy meters.  If you have a specific customer location that is in need of being processed via cellular, please contact ecc@cmsenergy.com with details.
