  • Hi jl_adino16,

    We would suggest that you try:

    (1.) Settings > Network & internet > SIM card> Disable and enable the SIM card
    (2.) Settings> Network & internet > Mobile network > Preferred network type> choose "2G/3G/4G" again.
    (3.) Power off your phone > reinsert sim card > turn on the phone
    (4.) Turn on airplane mode > wait for 3 seconds > then turn it off.
    (5.) Try using another sim card by a different operator
    (6.) Try resetting the network settings: Settings > System > Reset options > Reset WiFi, mobile & Bluetooth)

    If this problem still appears, what we would advise is that you have the unit sent in for an assessment and servicing where necessary.
    Sorry for any inconvenience this may cause.

  • I had the same issue, exactly the same firmware with JL Adino. It was fine, but suddenly since yesterday, it shows no network. My sim card is working on other mobile phones. Then I upgraded to android 10, the latest firmware that I downloaded manually from the Asus site, but the problem still exist.

  • Hi All,

    worst upgrade provided by Asus.Everytime they send new android update,No network issue happens.
