This allows phones locked to use a particular network to work on other networks.įor instance, in order for an iPhone locked to Verizon network to work with T-mobile and other foreign networks, the chip mimics the IMSI number and authentication key (Ki) of Verizon. Today, the Turbo SIMs are used to mimic the IMSI number and authentication key (Ki) supplied by the SIM card to the network.

This is done based on a series of coding on the microcontroller. The SIM uses a small microcontroller to block the traffic between the phone and the original SIM card, and then alter this traffic. I guess the technology was far ahead of its time. It was an amazing invention for phone users back then, but it wasn’t widely accepted. Examples of the early models include China3GPP, HyperCard, MagicSim and StealthSim. It was originally created in order to turn a single SIM phone into a dual SIM phone. What Is a Turbo SIM?Ī Turbo SIM card, also known as Unlock Chip, is an ultra-thin chip that is wrapped around a normal mobile telephone SIM card in order to modify its operation. You would need this information if you want to unlock the phone using an unlock chip. There are several tools on the internet that can help you figure out the carrier in which the phone is locked. And you can temporary fix the “Invalid SIM” or “SIM not supported” issue by using an unlock chip. However, these chips are often called Turbo SIM cards.
