The mobile phone has a unique identification code IMEI (International Mobile Equipment Identity), and is basically generated in a mechanism that only exists in the world, so various institutions are trusted.I use it as.
However, it has recently become news that frauds using this credit have occurred all over the world.
Recently, American police officers have a system error displayed on the Vivo smartphone that returned from the repair and cannot be used.It became clear.
As mentioned above, IMEI is basically managed to be one in the world, but in the above case, it is clear that more than 13,000 IMEI exists, which is organized.You can see that IMEI, which is valid for crimes, is stealing more than 13,000 units.
What is used for this valid IMEI is, for example, to be used to rewrite and use an expensive smartphone locked without paying the model price or usage fee, or a stolen smartphone IMEI.There are rewriting the IMEI of the smartphone used for crime and disguising the culprit to other humans.
Many countries have begun to illegally use the personal IMEI's rewriting act itself, and the act of rewriting the IMEI except for smartphone companies has no use other than these illegal activities, so it is easier to deter and strictly punish crime.So it's a natural movement.

IMEI is composed of 15 -digit numbers, and it has a structure called AA (company) BBBBBB (model) CCCCCC (serial) D (check -digit), so which smartphone is the first eight digits.Understand, a special calculation using the last number determines whether IMEI is correct.
It is a 15 -digit sequence that is quite troublesome to create if you think about it normally, but it is stolen by a mob of the US black protest activity recently, and it can be rewritten so that the iPhone locked by Apple can be used.There is a possibility, and it will be a necessary technology for criminal organizations such as theft group.
So what about the iPhone we are using?It is definitely safe to purchase from Apple or carrier and repair it at a authorized distributor, but it is not the case when repairing it with a flea market app or a non -regular repair shop.It can be said.
In Japan, there are not many records of such an incident, and there is no law that directly illegal IMEI rewriting, but it is not always the case that similar incidents will occur in the future, so in a reliable place you can buy in a reliable place.It may be better to try to repair it.
Some media assert that "Apple is not affected by this kind of fraud", but it is possible to jailbreak and jailbreak, but it is safe.Is dangerous.
By the way, there was a case where Apple was an IMEI fraud last year, and the case was "Selling an iPhone that made a fake IMEI for fake iPhone and replaced it with Apple."The news that earned $ 10 (about 100 million yen) became a hot topic.
