In conclusion, the Japan Communication SIM is a cheap SIM that allows medium-capacity data communication and domestic calls at a low price.

A plan that collaborates with a health management app and a data capacity currency in units of 1GB are also possible, so we can recommend it to many people.

We will explain in detail the merits and cautions of Japan Communication SIM along with the reputation posted on Twitter!

First, let's check the price plan and line speed, which are especially important when choosing a cheap SIM.

There are four price plans available for Japan Communications SIM.

Now that we've summarized the key points in the table, let's compare the plans.

*All prices include tax

You can choose your favorite plan according to your preferences, whether it's price-oriented, data-capacity-oriented, or calling and health management-oriented!

In particular, the "20GB plan" is more advantageous than the new rate plans of major carriers "ahamo", "povo" and "LINEMO", so we recommend it.

First, let's check the average speed of the Japan Communication SIM from "Minna no Net Line Speed", which aggregates and publishes actual line speed values.

The average download speed is 54.33 Mbps, which is sufficient, but the speed drops during times when many people use it, such as during lunch hours.

In order to understand the actual usage, we searched for people using Japan Communication SIM on Twitter and picked up reputation regarding speed!

We found a reputation for being fast even during the daytime when speed is hard to come by.

Since you are referring to other companies' lines, it is a review that is easy to refer to.

The actual measurement data is attached and is convincing.

The required speed for 4K video playback is said to be 24 Mbps, so if you can get 127 Mbps, which is more than five times that, you won't have to worry about slow line speeds.

On the other hand, I also found a reputation on Twitter that the speed is slow.

Looking at the reviews of users who connected during the daytime, it turned out to be a slow actual measurement value.

It's a common story that you can't get a comfortable speed depending on the busy time zone and communication environment.

It may be unavoidable because it is a phenomenon that can be seen in other cheap SIMs.

[Conclusion]Characteristics of people who recommend Japan communication SIM

In conclusion, we have listed the characteristics of people who recommend Japan communication SIM.

Why is it recommended for people like the above?

After this, I will explain the merits and cautions in detail.

Five Benefits of Japan Communication SIM and Reputation/Reviews

We will pick up 5 items and tell you what kind of benefits there are when you contract with Japan Communication SIM.

<5 advantages of using Japan Communication SIM>

1. 20 GB per month for 2,178 yen per month! Cheapest in the industry
2. Rational all-you-can-call plan with unlimited domestic calls
3. There is a unique plan in collaboration with the health management app "FiNC"
4. You can add data capacity for 275 yen per GB
5. The "i filter" option is safe for children

Since we also check Twitter's reputation for each item, Let's also listen to the voice of the user.

The main "20GB plan" of Japan Communication SIM is a cheap plan of 2,178 yen per month for 20GB per month.

Let's compare with the cheap plan "ahamo" where you can use the same DoCoMo line.

*All prices include tax

Comparing the tables, ahamo exceeds Japan Communication SIM only in actual measurements.

Actually, I found a tweet from a person who switched from ahamo to Japan Communication SIM!

The contents of the plan can be said to be an enhanced version of ahamo, so it makes sense that many people are considering and implementing a transfer.

If you choose the Rational Kakeho Plan, you can make unlimited domestic calls for ¥2,728 per month.

Some cheap SIMs that offer unlimited calling services require the use of a dedicated app.

However, with the Japan Communication SIM, you can make as many calls as you normally would, so it's easy to use.

This person also switched from Docomo to Japan Communication SIM and seems to be subscribing to the Rational Kakeho Plan.

However, the amount of data communication is limited to 3GB.

It can be said that it is a plan suitable for people who do not use data communication much, such as using it as a second smartphone exclusively for calls for work.

As an original plan of Nippon Telecommunications SIM, a unique "W smart plan" is provided in collaboration with the health management application "FiNC".

This plan has a basic data capacity of 3 GB and a monthly fee of 1,738 yen, but it is a revolutionary plan that adds 1 GB of data capacity for free if you walk 60,000 steps per month.

Even if you go back to Twitter at the time of the plan announcement, the reputation was excellent.

With Japan Communications SIM, after you have used up your data capacity, you can add 1GB for 275 yen.

The ahamo we compared earlier costs 550 yen per 1GB, but if you use a Japan communication SIM, you can add it for half the price.

It was also talked about in conversations on Twitter.

Even if you are worried about whether 3GB or 6GB of data will be enough, you can rest assured that you can add more data for 275 yen per GB.

There is a unique "i-filter" option that allows you to choose from 68 different filters to match your home.

"i Filter" is an option that allows you to shut out Internet communication related to a specific category for 396 yen per month.

Recommended for those looking for an internet connection for their children!

The main categories you can shut out are:

Block the above harmful sites and information You can safely leave your smartphone with your child.

Four points to note about Japan Communication SIM

Up to this point, we have picked up the merits and advantages, but there are four points to note about Japan Communication SIM.

[Notes on Japan Communication SIM]

1. Can't receive store support
2. Doesn't support 5G communication
3. Can't purchase a set of smartphones
4. Rational plan It is not possible to change the plan from " to "W Smart Plan"

We will also explain the above four points in detail with Twitter's reputation.

Japan Communication SIM realizes cheap rates by reducing operating costs to the limit.

Therefore, you cannot receive support from a physical store.

Even on Twitter, I found a user who felt sorry that they could not receive store support.

For those who want to receive detailed explanations at a physical store, this may be a big problem.

However, if you have never made an inquiry about internet connection before, or if you are accustomed to contracting online, the absence of a physical store will not have any negative effects.

If you don't have many opportunities to use face-to-face support, we recommend the Japan Communication SIM, which has a lower price.

Japan Communication SIM is not compatible with 5G, which has been a hot topic recently.

However, 5G lines are still expanding and cannot be connected in most areas.

Let's see DOCOMO's 5G area map!

This is a service area map of the Kanto region, but you can see that most areas do not support 5G.

At least at the moment, even if it doesn't support 5G, the impact is small and there is almost no problem.

See Docomo's 5G area map in detail

Please also note that you cannot purchase a Japan Communication SIM contract and purchase a smartphone as a set.

If the smartphone you are currently using is a docomo device, you can use the current smartphone as it is with the Japan Communication SIM.

However, SIM unlocking is required for terminals of other companies such as au and Softbank.

Let's take a look at the reviews of people who have actually experienced SIM unlocking.

I found a reputation that the procedure was easy.

You can connect by simply asking the company where you purchased your smartphone to unlock the SIM and inserting the new SIM card you received.

Be aware that there are some restrictions on changing plans after signing a contract.

We have prepared a table that summarizes the availability of plan changes.

As you can see, it is not possible to change from the 3 plans to the W smart plan.

If you want to join the W smart plan, select the W smart plan when you sign up for a new contract!

How to apply for a Japan Communication SIM

Here, we will explain the flow from application to activation, assuming that you are switching from a major smartphone carrier (au/Softbank) to a Japan Communication SIM (MNP). I will explain.

First of all, I have summarized what you need to transfer.

After that, we will tell you the details of how to apply for each flow.

A new SIM card for use with Japan Communication SIM will be shipped to the registered address.

How to cancel the Japan Communication SIM

Next, I will tell you how to cancel the Japan Communication SIM.

The procedure is simple, but let's check the contents for each flow.

1. 1. Login to My Page First, access the homepage of Japan Communication SIM and log in to My Page.

1. 1. Click the "Cancel" button. Click the button that says "Cancel".

1. Click the "Cancel" button on the confirmation page Click the "Cancel" button to complete the cancellation procedure.

You can't cancel after clicking, so think carefully before pressing the button!

Keep in mind that the cancellation will be the day before the recalculation date (the date when the usage is renewed and the monthly fee will be charged), not the immediate cancellation.

Monthly charges cannot be prorated, but instead, you can continue to use the Japan Communication SIM until the one-month contract expires.

3 recommended cheap SIMs other than Japan communication SIM

In addition to Japan communication SIM, there are many cheap SIMs with various features.

The following three lines are particularly recommended, depending on their characteristics.

I will explain each feature in detail.

SoftBank-affiliated Ymobile is a line that can apply the "Family Discount Service," which offers a ¥1,188 discount on the monthly charge for the second and subsequent lines when a family subscribes.

Let's check from the overview.

*All prices include tax

The family discount service can be applied to up to 9 lines in total, even for family members who do not live together.

Let's simulate a family of four!

*All prices include tax

The result is that you can earn 3,564 yen every month.

Compared to Japan Communication SIM, it has less data capacity and is relatively expensive, but if you want to use the same line with the whole family, Y!mobile is recommended.

The surplus data volume can be carried over to the next month, so even if you subscribe to a large amount of data, the risk of losing money will decrease.

For those who want to use a cheap SIM with a fast line speed, we recommend UQ Mobile, which records stable actual measurements despite the large number of subscribers.

Let's start with an overview.

*All prices include tax

UQ Mobile uses au 4G LTE and 5G lines with a population coverage rate of 99.9%, so you can comfortably access it from almost anywhere in Japan.

If you use the campaign "Tyr UQ mobile", the cancellation fee will be free if you apply within 15 days of the contract, so you can actually see how fast you can get from home.

In addition, if you apply the new rate plan "Home set discount", you can use the carryover plan from as low as 990 yen, whether you are alone or with a family of up to 10 lines in total.

*All prices include tax

As of January 2022, the measured value is lower than Japan Communication SIM and Ymobile, but it is recommended for those who want to have a cheap SIM that is well-balanced with the price.

If you want to buy a new smartphone along with a SIM, we recommend OCN Mobile ONE, which sells many devices including iPhone as a set.

First, let me give you an overview.

It is characterized by being able to contract with a small capacity of 1GB unit, and it is an attractive plan for people who do not use much data capacity every month.

Actual measurements are slower than the three companies introduced so far, but they use Docomo lines and are at a level that is sufficient for viewing high-definition videos.

Since the lineup of smartphones is abundant, it is also recommended for those who want to purchase a new smartphone with a SIM.

Depending on the timing, there may be a one-yen sale, etc., and you may be able to get an excellent model at a bargain price.
