Invalid Serial number from Iphone13 VN/A
My IMEI and Serial Number can be seen through my Apple ID. However, when I check it on http://checkcoverage.apple.com, it says it is invalid.
In https://appleid.apple.com/account/manage/section/devices, my iPhone is listed and with same Imei.
Device: Iphone 13
