Registration of Cel-Fi Signal Boosters

In some cases, regulatory bodies and or mobile network operators may require users to register the signal booster. If you received an “(Error 5) Registration Required”, or “(Error 9) Location Lock – Registration Required” you are required to register your device before you can continue boosting.

(Error 5) Registration Required
Before use you must register this device and have your provider’s consent. You must operate this device with approved cables as specific by the manufacturer. Systems can be registered via the WAVE application.

(Error 9) Location Lock – Registration Required
Your system has been moved from its original address. Please move the system back to its original location or register your new address with your wireless provider. Systems can be registered via the WAVE application.

Steps to Register

Step 1

Install your booster – follow the instructions in the separate Quick Start Guide. Wait for the system to complete the network selection. This can take between 5 to 7 minutes. When this process is complete an error message will appear on both displays indicating that registration is required.


Go to the App Store or Google Play Store and search for “Cel-Fi WAVE” to download our free app. The app connects to your Cel-Fi device via Bluetooth (requires Bluetooth 4.1 and Android 4.3 or newer).

Launch the WAVE app in close proximity to the Coverage Unit. The WAVE app will automatically connect to the Cel-Fi CU.


Once the application has connected to the Cel-Fi system, you will be prompted to register.
