might be,but when they came you could see that they have been printed out,just the same as an orange sim card,but you could tell they wasnt original because of the printing,somebodys onto a good scam

The old scam with these was to buy a contract phone with a stolen credit / debit card from one of the independant phone shops (very hungry for commission, and usually just left school). They then flog the phone to a second hand dealer or similar. They used to just bin the sim but realised people would give them money for the sim (used to be a lot higher than £20 but that seems to be the going rate these days).
The network provider has details of everybody that rings you, and everyone you ring. If the cards were obtained in a violent manner then it won't take the authorities very long to phone around and find you, Normal theft from vehicle, etc then they won't bother with you.........Your choice.

If you have access to SIMs for a certain ammount of time it is possible to clone them. The time is needed for some key extraction which is a bruteforce method.

Dye sublimation printers are available for printing.

Various generic cards can act as SIMs.

Two SIMs on a network will, at some point, trigger the network(s) to unauthorize both of them so it isn't advised or condoned.
