:clapping:The Simm card carries the Built Date and serial number of my original box to the Clone.
This means when you telnet into the original or the clone when the box is in setup mode you get access to the BIOS of the box.
On a clone with non original sim it shows the current booloader but as for serial number and Build date it shows as NA. no Data available.
Well if you replace this sim card with an original sim card your clone becames the original including the originals MAC address.
This is the easiest and secure way to spot a clone so far. Thanks a lot.
