    Your phone also has to be on the carrier list of 5 G supported phones. Ie your specific model.

    1. Check your country's available 5g bands,
    2. If your OP 8t is kb2003, check weather the update build number for the latest update is 11.0.11.11KB05BA, If it's 11.0.11.11KB05AA you got the NA version which i believe there's no n78 5g band.
