Anyone here using 5z jp version? (Network problem)

edited September 2020 in ZenFone 5 Series
I can't fix my network problem. Why Japan firmware is outdated among the other version. I have seen other version have Android Pie update and some simcard fix update. But this Japan version is too slow for a progress. I started to get disappointed to my device. Please do some checking here. I choose Asus because the developer here is Updated to what we need. But this Japan version sucks about the update.

Note: I'm done to all troubleshooting but still it can't fix. My only chance is an update.


  • Hi sao.fujiyama,

    Good day.
    Are your firmware version currently on JP-
    Please also help me to remove the SIM card, restart the device then re-insert the SIM card for a check.
    I would suggest you can try to reset the network settings.
    (settings> system> reset options> reset wifi, mobile & Bluetooth)

    Does this problem appear if you use a sim card of another carrier?
    Could you show me SIM status screenshot when you encounter this problem?
    (settings> system > about phone > status > sim status)

    Thank you.
