This is an attractive price plan that allows you to use unlimited data for 3,278 yen in months when you use it frequently, and you can use it for as low as 0 yen in months when you rarely use it.

However, if you are outside the Rakuten line area, you need to be careful as the speed limit will be applied if you exceed 5 GB per month.

However, Rakuten Mobile can be used at a medium speed of 1 Mbps even when the speed is limited.

If you get 1Mbps, you can search the internet, watch videos, and browse SNS without any problems, so you won't have any problems with daily use.

Rakuten UN-LIMIT Ⅵ's monthly fee is now free for 3 months.

Recommended cheap SIM with unlimited data capacity

As a cheap SIM with practically unlimited data capacity, we will introduce a service that allows unlimited use in low-speed mode.

The following three companies are major cheap SIMs that are easy to get enough speed even in low speed mode, so you can use them with confidence!

I will dig deeper into what kind of cheap SIM each is.

Y!mobile

The first thing I would recommend is SoftBank's sub-brand Y!mobile.

The sub-brand is a cheap SIM that can use the high-quality line of the main brand carrier service.

In other words, Ymobile allows you to operate your smartphone at a cheap rate while using Softbank's high-speed line.

It can be said that it is a service that combines the good points of a carrier and a cheap SIM!

The features of Ymobile are as follows.

*All prices include tax*Quoted from internet speed data for everyone as of March 2022

As shown in the table, Y!mobile Single Plan M/L allows you to connect to the Internet at 1Mbps even if the speed limit is reached.

If the speed is 1 Mbps, you can search the web and watch videos in normal quality.

Depending on the person, it can be said that it is a cheap SIM that can be used with virtually unlimited data capacity!

The reason why we recommend Y!mobile is that there are many attractive factors not only in terms of communication but also in terms of fees.

With Ymobile, if you use SoftBank Air or SoftBank Hikari together, "Home Discount Hikari Set (A)" will be applied.

If you apply the Home Discount Hikari Set (A), you can receive a discount of up to 1,188 yen per line from the Y!mobile smartphone monthly charge.

Also, even if you don't use Softbank Air or Softbank Hikari, if you have Ymobile users in your family, you can apply "Family Discount".

With Y!mobile's family discount, the same 1,188 yen discount as the Home Discount Hikari Set (A) will be discounted from the monthly charge for the second and subsequent smartphones, making it a great deal.

For those who say "1Mbps is fine" and "already using Softbank Air or Softbank Hikari", Y!mobile is the most recommended cheap SIM.

UQ Mobile

As a sub-brand of au, "UQ Mobile", which allows you to use a fast and stable line, is also a recommended low-cost SIM.

*All prices include tax *As of March 2022

UQ Mobile has abolished the unlimited plan it had previously offered, and has introduced a new rate plan called the “Kurikoshi Plan” from January 2022.

From September 2, 2021, the name was changed to 5G compatible “Kurikoshi Plan + 5G”, but it is a price plan with almost the same content except for 5G compatibility!

With "Kurikoshi Plan M and L", you can connect to the Internet at medium speeds of up to 1 Mbps even if you exceed your data capacity.

The notable point of UQ mobile is that you can connect without consuming data by switching to the saving mode available at 1Mbps.

If 1 Mbps is not a problem for you, you can save a lot of data by switching to high-speed communication when you need it in saving mode.

Also, UQ mobile can carry over data capacity, so if you use saving mode well, you can double the upper limit of each plan.

For those who want to use unlimited cheap SIM, it may be a good idea to control the data capacity with UQ mobile's saving mode.

[Count-free] Cheap SIM with unlimited data capacity for specific usage

So far, we have introduced cheap SIM cards with unlimited data capacity.

On the other hand, some cheap SIMs support "count-free" where data capacity is unlimited for specific usage.

If the target is a service that is used frequently, it will lead to overall data volume savings.

Let's check which cheap SIM supports which service.

We will explain what services the above two companies can use count-free, along with their respective characteristics.

Before knowing the services that can be used count-free, let's first check the general overview.

OCN Mobile ONE offers MUSIC count free service.

You need to apply separately, but there are no fees or monthly charges!

Let's check if the music distribution service you usually use is included.

If you want to save data capacity, use the "burst transfer function".

The burst transfer function is a function that enables instantaneous high-speed communication only when loading websites, SNS, etc.

Browsing the site can be used without stress as long as it can be read at high speed.

If there is a burst transfer function, many people will not be concerned about slowing down even when the speed is limited.

OCN Mobile ONE frequently conducts campaigns where you can purchase a terminal at a very good price by signing a set contract with a line.

There are some devices that you can get for as low as 1 yen, so if you want to get a device at a cheap price, don't miss the timing!

If you often use regular voice calls instead of apps such as LINE, please consider a cheap SIM with a "complete unlimited call plan".

Precautions for cheap SIM with unlimited data

A cheap SIM with unlimited data is a very convenient service.

However, there are some caveats to be aware of.

I will explain what you should pay attention to for each.

Speed ​​may be limited even with an unlimited plan

Even though you can use unlimited data, please understand that there are cases where speed is limited.

Of course, when you exceed the upper limit of the contracted data amount, even if you perform a large amount of communication in a short period of time, the speed may be limited.

It's important to choose a contract partner not only for the maximum amount of data, but also for the maximum amount of data that can be used in a day and the maximum amount that can be used in 3 days!

As long as you pay attention to such speed limit conditions, you can use the cheap SIM unlimited plan almost as if you can use it as much as you want.

Let's check the service content thoroughly.

Monthly charges are likely to be higher

Unlimited plans for cheap SIMs are likely to be more expensive than capped capacity plans.

If you want to keep the monthly fee as low as possible, you have to figure out your usual data usage and choose the best capacity plan.

Make sure you really need an unlimited plan compared to your current data usage before signing up.

Frequently asked questions about unlimited cheap SIM

Finally, we will answer the frequently asked questions about cheap SIM with unlimited data capacity in an easy-to-understand manner.

I will answer each question briefly, so please take a look.

Can you recommend a cheap SIM with unlimited data?

The following three companies are recommended for cheap SIMs with unlimited data capacity!

Strictly speaking, although it is not a cheap SIM, Rakuten Mobile, which allows you to use unlimited cheap smartphones, is the most recommended.

The above three companies are explained in more detail in [Recommended cheap SIM with unlimited data capacity]. In addition, Rakuten Mobile is explained in more detail in [If you want to use a cheap smartphone with unlimited data capacity, "Rakuten Mobile" is recommended].

Can I use tethering with a cheap SIM with unlimited data?

Many cheap SIMs with unlimited data allow you to use the tethering function for free.

However, the tethering function is likely to lead to slowdowns, and the smartphone's battery consumption will increase.

Therefore, it is better to keep tethering to the extent that it is used in emergencies, not for everyday use.

How fast is the "low speed mode" of a cheap SIM with unlimited data capacity?

The speed in low speed mode varies depending on the service you subscribe to, such as 200kbps or 1Mbps.

The table below summarizes the approximate communication speed required in real life.

If the maximum speed is 1Mbps or 1.5Mbps like this, you will have trouble using it normally. I don't think there are many.

However, if it is around 300kbps, it may be difficult to connect or you may not be able to use it.

Summary

This time, we have explained the features and recommended services for those who are considering a cheap SIM that can use unlimited data capacity.

From the conclusion, there are almost no cheap SIMs with completely unlimited data capacity.
