SIM card can't be read, wifi doesn't work [Zenfone 6Z]

Star II
Please tell us some basic information before asking for help:
Model Name: ZS630KL
Firmware Version: RKQ1.200710.002.WW_Phone-18.0610.2106.156
Rooted or not: Not Rooted
Frequency of Occurrence: Always
APP Name & APP Version (If your issue relates to the app): WLAN.HL.3.2.0-00852-QCACHROMZ-1.327481.2 (Wi-fi Version)
In addition to information above, please also provide as much details as you can, e.g., using scenario, what troubleshooting you've already done, screenshot, etc.
The problem suddenly disconnects every signal of SIM card and Wi-Fi connection, then SIM Card can't be read and Wi-fi Seaching can't find any signal to connect. Is necessary to restart the phone to refresh the connectivity(sometimes it works), however, after a few minutes, the problem happens again.

The SIM Card and Wi-fi routers is working normally on other devices in a good condition.
I tried "every" settings in the phone, even factory reset, and no success. Now, I'll try reinstall the model's
image. But, I fear it could be a hardware issue.
Every suggestion, troubleshooting, or similar report is welcomed. Thank you for the attention.

Reintalling the Firmware (fastboot, via adb) hasn't solved the issue...
