[Communication Cost Hack] Does AI also determine it as the "optimal solution"? A guide to using the "magic option" that achieves both unlimited data and a monthly cost in the 1,000 yen range with mineo

2025年11月30日 07:40

Hello. I am an AI Life Designer.

Last time, I talked about "letting AI manage your money to reduce fixed costs." Among those, the biggest fixed cost that many people face is "smartphone bills (communication costs)."

Paying 7,000 to 10,000 yen a month to major carriers is out of the question, but many people who have switched to budget SIMs may also be suffering from the stress of "not having enough gigabytes" or "being frustrated by slow speeds at noon."

In fact, there exists an "optimal solution that feels like a bug, where only those in the know benefit" in the budget SIM world.

That is the usage method using the option called "Packet放題 Plus" (Packet Unlimited Plus) from mineo.

As a result of having AI analyze and compare plans from various companies, the conclusion was reached that this plan is the most rational for fulfilling the selfish request of "I want to watch YouTube all the time, but I also want to use it normally at noon, and I want to keep it cheap."

This time, as an alternative to the low-cost-focused "My Soku," I will thoroughly explain the "My Pita" utilization technique that lowers costs without lowering your quality of life (QOL).

At the end of the article, I will also post a special referral link that makes the administrative fee free, so please be sure to read until the end.

1. Conclusion: Why is mineo the "optimal solution for the AI era"?

Usually, communication plans have a trade-off relationship where "using a lot of data equals expensive" and "cheap equals little data."

However, mineo has a unique way of thinking. That is the concept that "if you concede a little on speed, the data amount becomes unlimited."

Many modern contents (YouTube, SNS, music, Zoom) actually do not require ultra-high-speed communication (such as 50Mbps). Even 1.5Mbps is enough to work comfortably.

Major carriers: Selling more than necessary ultra-high-speed communication at a high price.
mineo: Providing necessary and sufficient speed at a low price with no limits.

From an AI-based "optimization" perspective, paying for an over-spec line is a waste. If you want to buy "only what you need" wisely, mineo is the only choice.

2. "My Soku" vs "My Pita": Which one suits you?

There are two main plans for mineo. If you get this wrong, it will cause stress, so let's organize it.

A. Maisoku (Obsession with low cost)

This is the plan I touched on briefly last time.

Features: Communication speed drops drastically (32kbps) between 12:00 PM and 1:00 PM on weekdays, making it unusable. In exchange, it is unlimited and extremely cheap at other times.
Price: 990 yen per month (Standard plan)
Recommended for: People who "don't look at their smartphone during lunch break," "are in a Wi-Fi environment," or "have it as a secondary line."

B. Maipita (A hybrid of comfort and low cost) ★Our recommendation this time

Features: Like typical budget SIMs, you can use it normally during lunch time. You can choose your monthly data capacity (1GB, 5GB, 10GB, 20GB).
Recommended for: People who "want to pay with PayPay during lunch break," "want to view LINE and SNS normally," or "want to use it as a main line."

For most people, "B. Maipita" is the safe choice if you are switching to it as your main line.

3. The ultimate trick: "Maipita" + "Packet Houdai Plus"

This is the main point.
With just "Maipita," it's over once you use up your gigabytes. However, if you add a magic option called "Packet Houdai Plus" (385 yen per month) to this, your world will change.

What is Packet Houdai Plus?

When you turn the switch ON, the communication speed becomes a maximum of 1.5Mbps.
In exchange, the gigabytes (data capacity) you are subscribed to will no longer decrease (unlimited usage).
You can also use it without restrictions at 12:00 PM.

In other words, it becomes possible to operate it by "keeping the switch ON for unlimited enjoyment of videos and SNS, and only turning the switch OFF to use high-speed communication for high-quality videos or heavy downloads."

Recommended combination: [1GB or 5GB + Packet Houdai Plus]

For example, what happens if you add this option to the "1GB plan"?

Maipita (1GB): 1,298 yen
Packet Houdai Plus: 385 yen
Total: 1,683 yen (tax included)

With this, you have completed a "smartphone with unlimited data that you can use even at noon for 1,683 yen per month."

Compared to the unlimited plans of major carriers (approx. 7,200 yen), this results in an annual saving of approximately 66,000 yen. This is the "communication cost hack."

Note: If you use more than 10GB in the last 3 days, restrictions will be applied to avoid congestion, but it is rare to exceed 10GB in 3 days (about 20 hours of video) with normal usage.

4. [Simulation] How much will you save by switching from a major carrier?

Let's simulate what kind of impact this will have on your household budget.

[Case Study: Mr. A, a company employee in his 30s]

Current: Unlimited plan from a major carrier
- Monthly: 7,238 yen
After switching: mineo (my-pita 10GB *)
- Monthly: 1,958 yen

*Actually, if you choose a "plan of 10GB or more," the Packet Unlimited Plus (385 yen) becomes free.

Monthly savings: 5,280 yen
Annual savings: 63,360 yen

What can you do with 60,000 yen?

Fill your new NISA quota
Use it as funds to buy a drum-type washing machine
Go on a luxurious hot spring trip once a year

Just by going through the procedure of swapping your SIM card once, this return will be generated automatically every year. Even in the world of investment, there is no project as certain and high-yielding as this.

5. Actual usage experience (The truth about pros and cons)

I will provide a realistic evaluation based not only on AI analysis but also on actual user voices (reputation).

Pros

Liberation from "Giga-death": You will no longer have to fear being "down to only 0.5GB" at the end of the month.
Peace of mind even during lunch hours: Unlike "Maisoku," you won't have to panic while PayPay spins at the checkout counter.
Supports 3 carriers: You can choose from docomo, au, or SoftBank lines, making it easy to switch while keeping your current smartphone.

Disadvantages (Things you should know)

The limits of 1.5Mbps: High-quality video (1080p or higher) and large app updates will take time. It is standard practice to do these over home Wi-Fi.
Speed drops during congestion: As is the fate of budget SIMs, speeds may drop slightly even in high-speed mode during morning rush hours or lunch breaks (though web browsing is still possible).

6. [Limited Benefit] How to waive the 3,300 yen administrative fee

For those who have read this far and thought, "Maybe I'll give it a try," here is some important information at the end.

Normally, when you sign up for mineo, a contract administrative fee of 3,300 yen is charged.
However, if you sign up via a "referral URL" from an existing user, this 3,300 yen will be waived**. Additionally, depending on the timing, campaigns that offer electronic money gift certificates may also apply.

If you have friends around you who use mineo, please get a referral code from them.
If you don't have anyone around you, you can use my referral link below.

Conclusion

The biggest enemy of reviewing fixed costs is the feeling that it is "a hassle."
However, the time required for this procedure is at most 30 minutes. If you think of it as work that creates 60,000 yen of value per year and 600,000 yen over 10 years in just 30 minutes, the hourly rate is incredible.

The AI era is an era where those who make smart choices become wealthy.
Please take this opportunity to cut into the "sanctuary" of your smartphone bill.
