1. Rakuten Mobile is the cheapest SIM with unlimited calls ( japan phone plans )

Rakuten Mobile can be used at the cheapest price compared to cheap SIMs and other major carriers. The secret is that you can make and make calls as much as you want using Rakuten Mobile’s dedicated app.

The price of Rakuten Mobile is quite challenging, as you can see when compared to other companies. Simply put, it’s the first carrier of choice for anyone who wants tethering or all-you-can-call with lots of data. This is a waste if you don’t know the plan of Rakuten Mobile.

2. Cheapest SIMs are often limited call time and not unlimited (japan phone plans )

Cheapest SIM can be understood by looking at the plans of each cheap SIM company written after this, but the unlimited time unlimited call plan is basically treated as an option. Therefore, each company charges a call charge of ¥22 / 30 seconds.

If you want to make unlimited calls with a cheap SIM, you need to add an option. However, as long as you don’t talk for a very long time, the cheapest SIM talk time is enough, so the cheapness of the plan is an advantage.

2.1 Difference between carrier and cheapest SIM ( japan phone plans )

The main difference between carriers and cheapest SIMs is in price and communication quality. Also, since cheapest SIM rents a line from a carrier, it is possible to provide a line at a low price. However, since the borrowed line is shared between subscribers, the line speed tends to be delayed in some hours such as daytime and nighttime.

Carriers are using the financial power of large companies to introduce cutting-edge technologies such as large-scale communication base stations and the latest edge servers at Rakuten Mobile, so communication quality is higher than cheapest SIM. On the other hand, the cheapest SIM has a lower communication quality, but it can provide a line with a communication charge of half of the carrier or less, so it is attractive that you can choose a free plan such as combination with a terminal.

Therefore, users can choose a carrier with good line quality or the cheapest SIM with the lowest monthly line charge. But recently, the fourth carrier, Rakuten Mobile, has entered the market.

As I mentioned earlier, Rakuten Mobile uses a new technology called edge server (cloud computing), which is characterized by its efficiency and low price. Of course, other carriers also use edge servers. However, other carriers are a key infrastructure of the country (KDDI’s communication failure recently caused a fuss) and are not as challenging as Rakuten Mobile.

Rakuten Mobile is a challenger in the career, so you can introduce more and more latest technologies and plans. As a result, we, as users, can also use all-you-can-use data and all-you-can-call at a low price.

Of course, there are some points that are slightly inferior to the communication quality of the three major companies, but that should be improved by future base station maintenance. Above all, as you can see from the plan, Rakuten Mobile is suitable for people who want to use all-you-can-call and all-you-can-use data communication because the monthly price is low.

3. Compare and introduce cheapest SIM companies with unlimited flat-rate unlimited calls ( japan phone plans )

Here, we will introduce each manufacturer that offers cheapest SIM. All manufacturers offer unlimited flat-rate unlimited calls and unlimited calling plans. Prices vary slightly, so it’s important to find a plan that suits you.

3.1 UQ Mobile

The call charge for UQ Mobile is ¥22 / 30 seconds (SMS shipping fee ¥3.3 / mail). Unlike Rakuten Mobile, there is no unlimited unlimited calling / calling between dedicated apps. However, UQ Mobile offers three options that can be selected according to the call volume.

Since the basic charge for UQ Mobile starts from ¥1,628 (monthly / 3GB), the monthly payment is the sum of this amount and the calling option. Therefore, UQ Mobile is a little more expensive than Rakuten Mobile, which starts at ¥980 monthly.

Rakuten Mobile makes domestic calls free by using the “Rakuten Link” app, and you can make calls to other carrier smartphones and landlines with the same phone number you are using. Therefore, you can make the most advantageous calls among cheapest SIMs. In addition, you can talk on the phone even in the low-speed data mode, so you can rest assured in case of emergency.

Rakuten Link is available for smartphones with Android 9 or later and iPhone 6s to iPhone 13 Pro with iOS 14.4 or later (recommended).

And from July 1, 2022, Rakuten Mobile started a service that allows you to make unlimited domestic calls and send and receive domestic SMS with the “OS standard phone application” within 15 minutes.

This unlimited call service of Rakuten Mobile is usually a monthly service of ¥1,100, but it is free for the first 3 months. In addition, all-you-can-call people have automatically upgraded from 10-minute all-you-can-call to 15-minute all-you-can-call. In addition, the OS standard message application (SMS) will be free to send and receive in Japan.

Rakuten Mobile has started a service that can compete with rival carriers and cheapest SIMs by starting Rakuten Link App and all-you-can-call domestic calls within 15 minutes each time. Among the major carriers, only Rakuten Mobile can make such unlimited calls, which is an advantage of choosing Rakuten Mobile.

Rakuten Mobile also has a wide range of terminals, from popular iPhones to in-house terminals, so it is also recommended that you can choose according to your budget.

If you select the mini plan + 5 minutes free call option, you can use it at a considerably cheap price. It’s a little more expensive than Rakuten Mobile’s 980 yen, but LINEMO is recommended for those who want to switch from Softbank to a slightly cheaper plan.
