It is reported that this kind of card was originally a patch card, but it was changed into a plug-in card without permission. Iccid will be printed on the regular card, but the number on the patch card is neither iccid nor card number.
So what is a patch card* This kind of card was originally fixed on the device and cannot be moved. * is strictly limited to the original IOT terminal equipment.
Tianyi IOT reminded that on the Internet, some illegal businesses privately transformed IOT patch cards into plug-in cards and disguised them as traffic cards for sales, harmed the public interest, and there were great security risks and service risks.
It should be noted that the IOT network card is strictly limited to IOT scenarios and IOT devices, and cannot directly sell bare cards to individual users.
