Discover the accurate method to check iPhone Lock carrier that not everyone knows

If you want to buy a used iPhone Lock but are concerned about the network issue, how do you know which network the iPhone is using accurately? There are many ways to identify the network the iPhone is using, but not all methods provide accurate results. So, follow the article below to learn how to check the network of a locked iPhone accurately and few people know about it.

What is an iPhone Lock?

An iPhone Lock is a term used to refer to iPhones that are network locked, meaning they cannot use the services of the locked network.

When you purchase a new iPhone, you will register to use a mobile network. The network will lock the iPhone to their network. If the owner of this iPhone transfers or resells it to someone else without deactivating the network account, the iPhone will still be locked to the original mobile network.

In this case, the buyer of the second-hand iPhone will not be able to use another network on that iPhone. They can only use Wi-Fi, without making calls or using mobile data. That is the iPhone Lock that people often refer to.

How to check the network of a locked iPhone accurately

Checking the network of a locked iPhone is an important step to determine the usability and suitable SIM card options. Below is a detailed guide on how to accurately check the network for a locked iPhone.

Step 1: Find the IMEI or Serial Number of the iPhone

First, you need to find the IMEI or Serial Number of the iPhone. The information about the IMEI/Serial Number will be displayed in the “Settings > General > About” section on your device.

Step 2: Use an online service

There are many websites to check the network of a locked iPhone. You just need to enter the IMEI or Serial Number into this website to receive information. Some websites provide free services, but most of them may require service fees.

To shorten the process of checking the network of a locked iPhone, you should check the original market of your phone. In the “Model Number” section, you will find codes like LL/A or J/A.

If it is J/A, please enter the IMEI/Serial Number into one of the following 3 websites:

• Docomo
• Softbank
• AU

If it is LL/A, please enter the IMEI/Serial Number into one of the following 3 websites:

• Sprint
• AT&T
• T-Mobile

Step 3: Check the network information

After entering the IMEI/Serial Number, the website will provide information about the network that the iPhone is locked to. This information includes the network name and the country the iPhone is locked to. If not, you can check other websites.

Note: Please make sure to use a reliable and secure website to avoid risks related to personal information security.

Limitations of iPhone Lock compared to genuine iPhones

Using an iPhone Lock (or network-locked iPhone) has significant limitations that users need to keep in mind. The following are the main limitations and the reasons why many users prefer to buy genuine iPhones.

Inconvenience of SIM card pairing

iPhone Lock requires users to use a complementary device called “SIM adapter” to work with networks other than the original locked network. This not only causes inconvenience during use but can also cause network connection and call stability issues.

No official warranty

One of the biggest limitations of iPhone Lock is that it does not come with Apple’s official warranty. This means that if there are any hardware or software issues, users will have to bear the repair costs or find unofficial warranty services.

Issues with new iPhone models like iPhone 14 and iPhone 15

For new iPhone models like iPhone 14 or iPhone 15, some markets no longer use physical SIM card slots and have completely switched to eSIM. This means that an iPhone Lock will have more difficulties in activation and usage with other networks, as there is no SIM card slot for pairing. In some cases, you can only use your iPhone as a media device without the ability to communicate or receive calls from other mobile subscribers.

Software updates and security

iPhone Lock may encounter issues when updating the latest iOS. Each update can lead to the loss of activation or the inability to use the SIM adapter, causing inconvenience and wasting time for users. In addition, using a SIM adapter can create security risks as it interferes with the device’s network system.

In general, an iPhone Lock may have a lower price compared to the genuine version. However, the limitations regarding SIM pairing, warranty, software updates, and security make this product less attractive. For users who want a stable and secure usage experience, choosing to buy a genuine iPhone from reputable providers like FPT Shop is a wiser decision. Moreover, the absence of physical SIM card slots in new iPhone models makes using an iPhone Lock more complicated and unreliable.
