Iphone 13pro max lost imei

The IMEI is built into the device, its part of the cellular hardware, it cannot be lost.

Go to Settings ➜ General ➜ About, and scroll down to the sim card sections. You should see 2 sections with 2 different IMEIs.

I press the code *#06# no imei appears, the mobile network is not readable, that means there is hardware damage, right?

No. Those codes don’t generally work with iPhones. As long as it shows up in Settings, then the phone is fine.
