Product No?

[Airplanet]

Are devices like mobile, wifi router, laptop and wireless earbuds etc have only IMEI No, Serial No or also Product no?

IMEI numbers relate to SIM cards, so any mobile devices that needs to connect to a mobile cell tower for broadband access will need a SIM card, and they are known to the ISP via the IMEI number.

as to serial and product numbers, almost every item that is produced will have either one or both of those.
