When considering a locked iPhone, one immediately thinks of the super affordable price these phones offer. However, a little-known fact is that using a locked iPhone nowadays is similar to using an international iPhone. Many current users still question whether it's worthwhile to purchase a locked iPhone. Let's delve into the advantages and disadvantages of these product lines.

Advantages of locked iPhones
One of the most compelling reasons to consider a locked iPhone is its significantly lower price compared to the international version. Despite the lower cost, it still delivers excellent features, allowing users to save a substantial amount of money.
Another noteworthy aspect is the wide variety of models and quality that locked iPhones often offer, providing users with an alternative choice to high-end international models.
Another point I find reassuring about locked iPhones is that these phones still receive Apple's warranty and support, just like international iPhones.
Disadvantages of locked iPhones

The first drawback of locked iPhones is that they get network-locked if you don't use a SIM interposer tool. This tool is designed to deceive Japanese carriers, as these phones are usually distributed and used in Japan and are only intended for Japanese residents. Therefore, when these phones come to Vietnam, local carriers cannot activate them. The most effective tool to 'repair' this type of product is the magical SIM interposer.
Another drawback worth mentioning about these phones is that they lack essential functions if you don't know how to Jailbreak or customize the system. Typically, when you buy this product, the store will assign an employee to perform these tasks for you.
Additionally, budget-friendly locked iPhones may experience instability in areas with weak mobile signals.

However, if you have the means, we recommend using international iPhone models for the utmost peace of mind.
