Hi ongrena1

Did you try restarting the phone? If still not working, you can check with their customer service here https://home.unifi.com.my/support/contact-us

Hi. Have you checked if your account is active? Sometimes I forgot to pay the bill so they suspended my line. You can check your line status via Myunifi apps also.

Hai @ongrena1  You can insert SIM card in other certified phones (band 5 - 850MHz) and monitor if the issue still persists.
