We all dread paying for costly mobile phone unlocking services.

But here’s the good news: you can make your device functional on any network using a GPP chip! Or, you can always purchase a GPP unlocked iPhone – they cost 40% less than factory unlocked iPhones, after all!

What’s that? You don’t know what GPP chips are?

Fret not, because this article discusses all about GPP chips and GPP unlocked iPhones, including their pros and cons.

So, let’s get started, shall we?

What Is a GPP Chip?

GPP chip (also called GPP LTE Chip) is a cloaking device that sits on your iPhone’s SIM tray. This Chinese-origin chip is typically placed on top of the gold-plated portion of the original SIM.

It impersonates your SIM card’s ICCID that identifies a specific carrier to allow you to bypass the original network’s access limitations. You can use a GPP chip to access any carrier regardless of whether your iPhone is country-locked, factory-locked, or carrier-locked.

A GPP chip is handy for people who travel frequently or live in regions where some carriers have limited signal coverage.

Placing a GPP chip in your iPhone doesn’t cause any interference in other functions. For instance, you can still update iOS to the newest version while having a GPP chip in your phone’s SIM tray.

Likewise, the latest GPP chip versions support LTE, even though they only facilitated 3G until a few years back.

What is GPP iPhone Meaning?

GPP iPhones are genuine iPhones previously locked to a wireless carrier, either local or international, but were made available to other carrier networks by utilizing a SIM-masking chip known as “GPP.”

GPP unlocked iPhones are also called “semi-factory unlocked” devices that don’t compromise the phone’s performance. GPP unlocked iPhones are less expensive than factory-unlocked iPhones. However, they are not fake copies of the originals.

The reason for their low selling price is that the bulk of these devices are reconditioned. This means they had a factory problem that the company has repaired with Class “A” structural components. Another possibility is that these devices are region or network-locked, probably the stolen leftovers from Korea, and Japan.

GPP iPhones are usually unlocked via GPP/R-sim/X-sim/Turbo SIM and are a part of a postpaid plan. Because these phones already have GPP chips inside, you won’t have to worry about whatever SIM card you use.

Pros and Cons of GPP Unlocked iPhone

If you’re thinking of purchasing a new GPP-unlocked iPhone, it’s a good idea first to understand the benefits and drawbacks.

We have listed the key points to help you decide whether or not to go ahead with the purchase:

Pros of GPP iPhones

1- Major Savings

GPP iPhones are less expensive than the original devices, so you don’t have to purchase an overpriced mobile unlocking service. Even if you don’t buy a GPP iPhone, you can invest in a GPP chip to make your device fully functional on other networks.

2- Allows You To Switch Between Different Network Carriers

You can convert your network-restricted iPhone into an open line by modifying the GPP chip’s ICCID.

3- No Lengthy Unlocking Procedures

Semi-factory unlocking your iPhone is a straightforward procedure. It saves you the time of contacting your network carrier and waiting for them to unlock your device.

4- Uninterrupted Access to All iPhone Features

Cons of GPP iPhones

1- Incompatibility with the Latest iOS Versions

Not all GPP chips are compatible with the latest iOS updates, so your GPP unlocked iPhone might stop working. As a result, every time you receive an iOS update notification, you must update the GPP chip itself.

2- SIM Card Issues

GPP Unlocked iPhones usually fail to identify your local SIM card after upgrading to the latest iOS versions. So, you might run into SIM-related issues like SIM Not Valid or SIM Not Supported prompt messages, fluctuating signals, and no access to data connections.

3- Constant Updates

Constantly updating your iOS version has several issues. For instance, you will have to wait until the GPP chip vendor develops a compliant version. Secondly, purchasing a compatible GPP chip to operate on your current iPhone means extra costs.

4- Older Versions Do Not Support LTE

Even though the more recent GPP versions support LTE, the older ones are only compatible with 3G. So, you might have to purchase an up-to-date version if you don’t already have one.

Should You Update GPP Unlocked iPhone?

Updating your GPP unlocked iPhone has its pros and cons. Your GPP chip will stop working if the update includes a fix. Apple is also updating and restricting ICCID, requiring you to reactivate your device.

However, the recent GPP versions allow you to manually alter the ICCID so that it will continue to work with future iOS releases.

Some users have also confirmed that removing or reinserting a SIM card and resetting your iPhone to factory settings after the current update would only cause minor issues, and you may continue to use the GPP chip.

You should keep these in mind before updating your GPP unlocked iPhone.

GPP Unlock Vs. Factory Unlock

Factory unlocked iPhones are a genuine open-line copy of the iPhone. You can enter any SIM card without utilizing GPP chip.

GPP unlocked iPhones, on the other hand, have a GPP chip already inserted into the SIM tray and an original SIM card placed above it to impersonate the SIM’s ICCID. This sort of unlocking is temporary, and you may need to update all of the types of Apple publishes a new version.

When we compare the benefits of factory unlocked phones to GPP unlocked phones, it is evident that factory unlocked phones are far easier to use and handle. Unlike GPP unlocked iPhones, factory-unlocked devices can survive the most recent IOS issues without compromising performance.

The Endnote

This brings our discussion to an end. Whether GPP chips are suitable for you depends on your preference. If you are comfortable with the drawbacks, you can settle for GPP iPhones.

In the contradicting scenario, you can unlock your iPhone using the alternative methods listed in this article.
