The turbo sim is a device that is used to circumvent the factory unlock on iPhones, many times on those that do not have the factory unlock available to apply to it, other times because they do not want to pay what is required to unlock phone. Turbo sims are programmable. Sometimes they work quite well, but other times they fail.
It is an “unlock” method that Apple doesn’t like, so Apple is always working to knock them down, while turbo sim manufacturers are always looking for ways to get new turbo sim models out with new programming.
When the manufacturers win the battle, the turbo sims behave stable. They make you feel that the iPhone was unlocked at the factory, but when the user begins to feel comfortable because Apple appears and manages to knock them down and the turbo sims return to not working for a while, those that were already working continue functioning.
At the time that the turbo sims cannot be programmed, or do not work at all well, the same stores that sold you the iPhone with turbo sim, generally do not receive it back if you want to change your iPhone for a more advanced one. Therefore, you have to search almost all to be able to unlock iPhone.
Another risk is that if your iPhone fails software at the same time that the turbo sims are not being able to be programmed, then, by solving the software problem, you will remain sim signal services, because the turbo sim programming is lost.
As an owner of a mobile phone store, do not sell iPhone’s with turbo sim, to avoid possible future inconveniences to your customers, since we know that buying an iPhone can take a lot of effort.
