Turbo SIM Review: Does It Work to Unlock Your iPhone?

Altering how your smartphone connects to the carrier might seem scary but in reality, it’s a normal activity that brings a lot of benefits.

One tool that you can use to do this is Turbo SIM, a special device that is designed for modifying a smartphone’s SIM card connectivity.

People new to this concept have had a lot of questions about the device and whether it’s safe, if it actually works, and if the pros outweigh the cons.

In this article, we’ll be reviewing Turbo SIM to answer all of these questions and help you make a decision on whether or not to use it.

Part 1. Turbo SIM Review

In the first section of this review, we’ll be focusing on Turbo SIM specifically, as well as introducing you to the method behind using it.

1. What is Turbo SIM?

Turbo SIM is an iPhone unlock chip that you insert into your smartphone alongside your SIM card which removes any carrier locks. This means that when you have this device inserted, you’ll be able to connect your smartphone to any other carrier network even if a carrier lock is active.

Turbo SIM currently only works with smartphones that are on a GSM network. Therefore, if your phone is on a CDMA network, you won’t be able to take advantage of this technology.

Major GSM & CDMA Carriers

  • T-Mobile
  • Verizon Wireless
  • U.S. Cellular
  • Sprint

2. How Does Turbo SIM Work?

Turbo SIM falls into the category of hardware unlocks, as opposed to software unlocks. In other words, technically you will be altering your smartphone’s hardware in order to bypass the carrier lock which in the eyes of many professionals can be risky.

How does it work?

You insert the Turbo SIM device into your SIM card tray as instructed and once the device activates, your smartphone will operate as though there is not an active carrier lock.

It’s relatively straightforward compared to other hardware unlock methods (especially considering that you don’t have to open up your device and modify the hardware yourself) although that doesn’t mean there are no risks associated with it.

Part 3. FAQs About Turbo SIM

Before we wrap up this Turbo SIM review, this final section will be covering some of the frequently asked questions that we see users asking about the device.

Are all Turbo SIMs compatible with my iPhone model? 

This is not the case. There are different types of Turbo SIMs available depending on your iPhone model as well as the iOS version that you have installed. Be sure to do your research and make sure you are buying the right device before purchasing anything.

How do I update iOS with Turbo SIM installed?

The only option you have is to buy a newer Turbo SIM. After you update your iPhone’s iOS version, the current device will no longer be compatible and therefore your carrier lock will return.

Once you insert a Turbo SIM which is compatible with the newer iOS, the carrier lock will be disabled again.

Which is better, a factory unlock or using Turbo SIM?

This is a matter of opinion. In some cases, a factory unlock is ideal, such as if you don’t want to risk damaging your SIM card.

Overall, Turbo SIM can be an effective tool for bypassing your carrier lock but it’s also true that there are a handful of risks and downsides that come with it. For one, it will only work if you’re on a GSM network (CDMA networks are not compatible).

What stands out more is that if you want to keep your iPhone up-to-date with the latest features, you’ll need to keep buying new Turbo SIMs. That’s why a more permanent solution, like the DirectUnlocks service, is ideal and is our recommendation.
