Identify the exact receiving product
Write down whether the receiver is an integrated Xumo television or an external Xumo Stream Box. For a TV, use Xumo’s Berry/Teal identification guide. The Settings menu and on-screen branding are the documented clues; a similarly coloured app icon on the phone is not sufficient.
Xumo says the Xumo TV mobile app for iOS works with its Berry television route and cannot pair with the Stream Box. It separately identifies Xumo Remote for Teal televisions and Stream Box. A wrong-app installation can therefore fail despite a working phone and television network.
Establish the pairing state
Follow the current publisher link and supported-phone requirements for the identified route. For Berry pairing, Xumo says the TV must already be activated with its home screen visible, online and on the same network as the mobile device. The app then selects the TV and accepts the code shown on screen.
Check those prerequisites before deleting an existing app configuration. An activation screen on the television is a different stage from a home-screen device waiting for a remote-app connection. Keep the pairing code private and confirm that the listed device is the television you intend to control.
Compare discovery and control separately
Once pairing completes, try a simple navigation action before using playback or volume controls. Seeing the device in a list establishes discovery, while a successful key action establishes a later control stage. Record which of those stages fails.
If the correct app still cannot pair, include the television or box model, interface version, phone OS and whether activation was complete. State that both devices were on the intended network without exposing network credentials. This report separates app compatibility, television setup and local discovery instead of treating all three as a single internet-speed problem.
