Device shows no connectivity

Note

Prepare devices before field installation. This allows networks to recognize the device faster.

Initial steps

1. Verify your phone has adequate connectivity in the store. Move closer to the installation location and, if applicable, inside the refrigerator or freezer to test if the door or glass is blocking the signal.
2. If available, test another VistaZ device to determine if the issue is device-specific.

If only one device lacks connectivity, it's likely a device issue related to manufacturing or transportation. The SIM may be dislodged or battery connectors may be misaligned. Troubleshoot first to avoid replacement logistics.

Device debugging

1. Obtain required tools
2. Verify the SIM is fully inserted
3. Test connectivity again
4. Close the device lid

If connectivity does not resume, contact support for replacement.
