The Pitfalls of the "1-Yen Smartphone": Hidden 주의사항 and Disadvantages Behind the Low Price

"Is it true that I can buy a smartphone for 1 yen?" "I want to keep costs as low as possible!"
Many people are probably considering a "1-yen smartphone" with such thoughts in mind. However, behind the attractive 1-yen price, there are unexpected pitfalls.

This article explains the mechanism and注意事项 of 1-yen smartphones, checkpoints to avoid regretting your purchase after signing a contract, and how to utilize [PRODIG] as a cost-effective and safe way to obtain a smartphone.


Why can you get a smartphone for 1 yen? Explaining the mechanism

First, the reason 1-yen smartphones exist is not that "the device price is 1 yen," but rather that it becomes "effectively 1 yen on the condition of a communication contract."

Carrier Encirclement Strategy

Major carriers aim to attract and retain users by offering significant discounts on the condition of a new contract or number portability (MNP).

  • Smartphones normally priced at 70,000 to 100,000 yen become 1 yen.

  • However, the "monthly communication fee" is often set higher.

  • It is almost always bundled with a 24-month installment plan.

Thus, it is difficult to buy only the device cheaply, and the actual total payment can be surprisingly high in some cases.

Common Pitfalls and Precautions with "1-Yen Smartphones"

There are several common patterns for why many users regret their purchase after signing a contract due to the attractive low price.

1. High communication fees make it actually expensive

In many cases, 1-yen smartphones come with high monthly communication plans, and it is not uncommon for the total cost over two years to exceed 100,000 yen.

2. Cancellation fees may apply

If you cancel within a certain period, you may incur cancellation fees ranging from several thousand to tens of thousands of yen. It is necessary to check the fine print of the contract.

3. SIM lock and restrictions on free switching

Some 1-yen smartphones come with a SIM lock, making it difficult to use SIMs from other carriers or to use the device for other purposes.

For cost-performance, the optimal solution is a combination of "refurbished smartphones" and "low-cost SIMs."

"I thought I got a good deal with a 1-yen smartphone, but it actually ended up being a loss." To avoid this, the combination of a refurbished smartphone and a low-cost SIM is gaining attention.

What are refurbished smartphones?

  • Smartphones that have been inspected, cleaned, and had their operations checked by a specialist company, then resold.

  • They offer more peace of mind regarding quality than used phones, and are priced lower than new phones.

  • At PRODIG, all products have their battery status checked and come with a warranty.

Reduce monthly costs with low-cost SIMs

  • A wide variety of plans are available for around 1,000 yen per month.

  • Sufficient content for calls and data communication.

  • Free to cancel and switch carriers.

Combining these two can significantly save on the total cost of "device price + communication fees," and also increase the freedom of your contract.
