What is a major carrier, SoftBank's cheap SIM "Y! Mobile"?
Before seeing the word -of -mouth and reputation of Y! Mobile, let's first check what kind of cheap SIM is Y! Mobile.
Y! Mobile is a cheap SIM company operated by SoftBank, one of the major carriers.
The three major carriers have no group -like associations, and many companies offer their own cheap SIM services, but Y! Mobile is characterized by strong involvement with SoftBank.
Of course, SoftBank and Y! Mobile are different companies and services, but SoftBank, who has developed communication services as a major carrier, can be expected to have a comprehensive service quality.
For example, those who feel this are a very recommended company.
However, since it is a smartphone that is used every day, I would like to check the details of the monthly fee and communication speed before contracting.
We will organize the four points above.
The monthly fee plan for Y! Mobile is as follows.Y! Mobile's price plan is characterized by the three plans of S, M, L.
| 項目 | シンプルS | シンプルM | シンプルL |
|---|---|---|---|
| 月額基本料（税込） | 2,178円 | 3,278円 | 4,158円 |
| 家族で加入したときの2回線目料金（税込） | 990円 | 2,090円 | 2,970円 |
| 通信容量 | 3GB | 15GB | 25GB |
| 容量超過後の速度 | 300kbps | 1Mbps | 1Mbps |
| 5G対応 ※一部エリアのみ | 〇 | 〇 | 〇 |
| 通話料（税込） | 22円/30秒 | 22円/30秒 | 22円/30秒 |
* All prices include tax * All prices and prices are as of November 2021.
Y!mobileでは家族割引サービスが使えるため、家族で契約した2回線目以降の料金がとても安くなるのがポイントです。さらに5～18歳の方ならワイモバ親子割適用でさらに安くなります。（2021年11月現在のキャンペーンです）
Unfortunately, Y! Mobile does not officially disclose the normal communication speed for each plan, so the fact is that you do not know unless you actually use it.However, there are four points that know the high communication quality.
First of all, being a cheap SIM operated by SoftBank, and the use of SoftBank lines is a major point that can be expected to be the speed of communication.
そしてY!mobileは、キャリアアグリゲーションとMassive MIMOといった最新技術を導入して通信環境の整備を行っています。
＜キャリアアグリゲーション＞単一ではなくいくつかの周波数から形成された電波を使って一つの回線を作り、通信速度を高める・つながりやすくする技術のこと。
＜Massive MIMO＞読み方はマッシブ・マイモ。ユーザーごとに使える専用の電波を割り当てることで、電波をキャッチしやすくする技術のこと。
This certainly seems to be expected to be the speed of the communication speed.In fact, users who measured the speed with the app also have a reputation for saying that "40Mbps was out on the descent".This speed is quite fast as a cheap SIM.
In addition, when the communication capacity is exceeded, the following speed is used, which is published as official information.
| プラン | シンプルS | シンプルM | シンプルL |
|---|---|---|---|
| 容量超過後の速度 | 300kbps | 1Mbps | 1Mbps |
Simple S has a large cut of 1Mbps, so you may feel a little difficult to connect when overtime.You can see that simple M / L is a very high -speed communication of 1Mbps even under the speed limit.For this reason, especially with simple M / L, it seems that it can be used with some confidence when giga is running out.
Ideally, if you switch to Y! Mobile or sign a second smartphone, you can sign up.From now on, we will introduce some of the current Y! Mobile campaign information.
* Information is as of November 2021.Please be sure to check the official information when using the campaign, as it may end depending on the season.
| 項目 | 内容 |

Y!mobileは、数ある格安SIMキャリアの中でも実店舗のあるキャリアです。そのためオンラインではなく店舗で手続きしたいと考えている方も多いでしょう。
So, which is more advantageous between stores and online in Y! Mobile transfer and new contracts?
結論からいうと、おすすめはオンラインショップです。Y!mobileの店舗とオンラインストアでは、主に次のような違いがあります。
| 店舗タイプ | オンライン | 店舗 |
|---|---|---|
| 事務手数料 | 無料 | 3,300円(税込） |
| 送料 | 無料 | - |
| 待ち時間 | なし | あり |
| 受付時間 | 24時間365日 | 営業時間内のみ |
このようにオンラインストアでは、契約事務手数料が無料になる特典が受けられます。端末やSIMカード発送における送料も無料なため、基本的に必要以上に費用がかかることはありません。
There are many other advantages that there is no waiting time and the reception time is 24 hours and 365 days.
Online store -only campaigns are also conducted in some time, so if you get lost either store or online, we recommend online.
Y! Mobile reviews and reputation summary
The next thing you want to check is the various word -of -mouth and reputation of Y! Mobile.
Y! Mobile has various recommended points such as communication speed and price plan.But what is worrisome is the user's opinion.
While checking various reviews, let's organize the good points and concerns of Y! Mobile.
Name: DJ Yuki Hamu/Gender: Female/Quote
The monthly fee plan of Y! Mobile has a reputation such as "cheap".
Because it is a cheap SIM, the price is considerably cheaper than a major carrier.There will be some parts that seem cheaper than other companies of cheap SIMs.
However, recently, it has been an era where the price reduction competition of each company is fierce.A new brand, LINEMO, which has a cheap price, has also begun at SoftBank of the same group.
Therefore, it is true that Y! Mobile is not particularly cheap just because it is a cheap SIM.
If you simply sign a smartphone with emphasis on the cheapness of the price, you need to compare and select the rates of each company.
Name: Admiral ＠ Ota 2nd/Gender: Male/Quote
As of November 2021, Y! Mobile
We mainly handle smartphones.
Although the lineup is not small, if you want a higher -performance model, the performance of the smartphone that you are honestly handled is the impression that it is still a good idea.
ただし、あくまでヘビーにゲームや動画を楽しむユーザー向けの話です。iPhoneも最新機種、よりハイスペックな機種ではないとはいえiPhone 12の取り扱いがあります。また、ミドルスペックとしてコスパ最強といわれる「XiaomiのRedmi 9T」や、人気のSONY・Xperiaシリーズも普段使いなら十分事足りる性能です。
Therefore, it is up to each person to see the lineup and feel unsatisfactory, but there are many specifications that are not troubled when using it everyday.
Name: Umi/Gender: Private/Quoted source
Name: Ko [Kawasaki citizen] MTG/Gender: Male/Quoted source
Regarding the communication speed, there were many word -of -mouth and reputation, such as fast and easy to connect.
As you can see in the word -of -mouth and reputation introduced, it seems that there is quite a lot of expectations for speed at low speed.
However, despite the improvement of the communication environment, it seems that it may be difficult to connect depending on the time of day and location.
回線が混雑しやすいお昼時、18時以降の時間帯は、格安SIMは速度が制限されやすいとされています。そのためこれらの時間帯に使用すると、「遅い」と感じることもあるでしょう。
For those who want to reduce the price by cheaper SIM, but want to be slow, Y! Mobile is suitable for those who want to be slow.
Name: Echigo Samaro/Gender: Private/Quoted source
Name: Toriko/Gender: Private/Quote
Y!mobileは、限定エリアのみ5Gに対応しています。
While there are many cheap SIMs that have not been introduced 5G, it is very nice that high -speed communication and large -capacity communication can be done with cheap SIM.There are word -of -mouth and reputation that the speed is actually fast.
Therefore, if you live in an area where 5G communication is possible and want to use large -capacity high -speed communication, Y! Mobile is a highly recommended cheap SIM.
Other word -of -mouth and reputation for services were related to customer support.
It seems that there are quite a few things that do not go well when trying to contact telephone support, and it is difficult to solve questions and troubles.
そのため格安SIMの取り扱いやスマートフォン関連のトラブルに苦手意識を持っている方は、Y!mobile契約後に困ってしまうシーンも出てくるかもしれません。家族や知人、周りにいる詳しい方に教えてもらいながら使うのが良いでしょう。
Benefits of Y! Mobile's reviews and reputation
Let's organize specific advantages and disadvantages based on the word -of -mouth and reputation of Y! Mobile.First, list the benefits:
Let's take a closer look at each point.
The speed of the communication speed of Y! Mobile is one of the high -quality SIMs.As mentioned in the previous section, in Y! Mobile,
以上のような最新通信技術の導入を行っています。そのため比較的通信は安定しています。実際に、口コミ・評判を見る限り「速い」といった意見もよく見られます。
そのため料金プランも見ながら判断すると、「通信品質もしっかり保たれているコストパフォーマンスに優れた格安SIM」といえるでしょう。格安SIMを契約することで速度の遅さに悩まされたくない方におすすめです。
Y!mobileには、格安SIMには珍しく、家族割引のサービスがあります。他社と比較しても、この割引があることは大きなアドバンテージとなるでしょう。
The details are as follows.
| 項目 | 内容 |
|---|---|
| 割引の名前 | 家族割引サービス |
| 割引金額 | 毎月基本料金から1,188円割引 |
| 対象プラン | シンプルS・M・L 1回線目・2回線目以降ともに対象" |
| 回線数 | 9回線まで |
| 家族の定義 | 家族（血縁・婚姻）もしくは同住所 血縁・婚姻関係にある家族は別住所OK |
* Information as of November 2021.
このようにY!mobileで家族割引サービスを利用すれば、毎月1,000円（税込）以上も割引を受けられます。さらに家族として該当する範囲が広いのも非常に嬉しいところです。
For example, a cohabiting lover who is not related to blood, or a husband or wife on the inner relationship is also eligible for the discount service under the same address.The more you use it, the better you use, so if you think about Y! Mobile transfer or new contracts, I would like to consider using it with the whole family.
Y!mobileでは、データの繰り越しが簡単かつ無料でできます。
There is no need to apply in advance or make any settings, and you will be free of charge and you will be able to make a lot of data capacity until the next month.
For example, a simple M plan has a communication capacity of 15GB, but if it is 5GB a month, 5GB can be traced in the next month, so the following month will allow high -speed communication up to 20GB in 15GB + 5GB.Therefore, it is a nice service for those who have more space.
By the way, considering using this free service, Y! Mobile contract is recommended near the end of the month.
For example, even if a contract is contracted on the 25th, the communication capacity of the plan will be attached to the full day, so the more the billing start date, the higher the data capacity that can be carried over.
Y!mobileは、販売している端末も含めて多くの端末に対応しています。そのため乗り換えで他社製のスマートフォンを持ち込む場合でも、SIMフリー端末あるいはSIMロック解除済端末なら基本的に問題ないといえます。
As of 2021, many of the models handled in the market, including smartphones sold in carriers, are SIM -free or SIM unlocked terminals.
For this reason, popular smartphones such as iPhone, Galaxy, Xperia, and Huawei can basically be used on Y! Mobile.
By the way, the official website of Y! Mobile has a page that allows you to search for SIM operation confirmed models.
Y! Mobile official homepage SIM operation confirmed model list page
In this page, you can search not only Y! Mobile sales terminals, but also a wide range of other companies such as docomo, SoftBank, au, UQMOBILE, and Rakuten Mobile.
Therefore, when switching, make sure that the target terminal has been confirmed.
5Gに対応しているのもY!mobileの強みの一つといえます。5G通信が可能な場所では高速の大容量通信が可能になるため、外出先でもサクサクネットにつながるのが魅力です。
By the way, the cheap SIM that supports 5G is as follows.
In this way, there are not so many cheap SIM carriers that support 5G communication.Therefore, it is a great advantage to be able to use 5G communication while having a cheap price.
The 5G communication area of each company, including Y! Mobile, is still limited.Only in Tokyo, the center of each prefecture, and some areas can be connected to 5G.Still, it is an advantage for those who live in a corresponding area.
Disadvantages from Y! Mobile's reviews and reputation
From now on, we will organize the disadvantages of Y! Mobile based on word -of -mouth and reputation.Y! Mobile has various excellent points such as communication quality, but it is also pointed out that the following is the following, so be sure to check it out when contracting.
The price of Y! Mobile is not so cheap compared to other cheap SIM companies.Therefore, it is a brand that is not suitable for those who value the cheap price anyway.
There are many other cheap SIMs that can be used cheaper than Y! Mobile with the same data communication capacity, especially for those who do not usually use the Internet, for example, a plan of 1GB or less, for example, Rakuten Mobile.There is a possibility that a place like a certain place is more suitable.
The reason why the price does not become so cheap is
Is related.There is also a discount service that allows you to use family discount services cheaply.For this reason, Y! Mobile is suitable for those who have benefits, including family discount services and other services.
口コミや評判の中には、料金プランのわかりにくさを指摘する意見もあります。
Y! Mobile's price plan is a lot of money written with family discount services and parent -child discount campaigns that are being implemented as of November 2021.
For this reason, when you look at the official website, you often don't understand, "Which price will you end up in the end?"
If you do not know your own price plan, we recommend that you calculate the price directly at Y! Mobile stores.
In recent years, unlimited data plans have been attracting attention, led by Rakuten Mobile's UN-Limit.
The unlimited data plan is characterized by unlimited communication under some conditions, as the data capacity is not determined as "〇GB" as the name suggests.This is a very nice point for smartphone heavy users.
しかし、Y!mobileにはこのデータ無制限のプランがありません。
The maximum data communication capacity has a maximum amount of increase option, up to 30GB, and even if it is carried over the previous month, it is less than 60GB, so it is not possible to communicate data without worrying about the capacity at all.
Therefore, if you do a lot of data communication without Wi-Fi communication, it may be better to select a carrier with an unlimited data communication plan.If you look at your own data traffic, if you are not enough at up to 30GB, you should consider other companies instead of Y! Mobile.
口コミや評判を見ると、Y!mobileでは一部、サポートの質が悪いといった声もあります。
Some people said that they were not connected to telephone support, and were guided to chats and did not solve any trouble at all.
Even when you actually open the inquiry page from the official website, it is difficult to get guidance by telephone.
This is considered a countermeasure to eliminate the difficulty of supporting support, but it is often difficult if it is difficult to contact in case.
ちなみにオペレーターと話したい場合は、スマートフォンから「151」をダイヤルすれば通話できます。
However, it seems that it is not very good when it is crowded, so in order to use Y! Mobile comfortably
It may be more relieved to prepare the condition and environment as described above.
Y! Mobile uses a SoftBank line, so you can communicate without any problems if it is an area where SoftBank radio waves communicate.
しかし、山間部の地域では、ときどきつながりにくいと感じることもあるようです。田舎や山奥ではエリア拡大が進んでいない関係で、Y!mobileに限らず、他社格安SIM、あるいは大手キャリアでもつながりにくくなることはあります。
Therefore, if you live in a mountainous area or travel to such an area at work and use a smartphone, you may be more relieved to have a higher communication quality and stable major carrier.
Those who recommend Y! Mobile
Now, let's check the features of Y! Mobile recommended and those who are facing based on the advantages and disadvantages and reputation you have seen so far.
Those who recommend Y! Mobileは、通信速度が速い格安SIMを使いたい方です。
There are Y! Mobile and UQ Mobile for cheap SIMs that have a good reputation for communication speed and stability.Reason,
This is because it is related.For this reason, the two companies have a reputation that the two companies have a faster communication speed as cheap SIM and can be used relatively comfortably.
"I want to use a cheap SIM, but I want to avoid slower communication speeds," so many people are worried about a cheap SIM contract.
Y! Mobile, which has a reputation for being fast for such people, is highly recommended.
Y!mobileでは、契約中の特典として無料でYahoo!プレミアム会員になれます。通常Yahoo!プレミアム会員は、月額508円（税込）の料金がかかるため、年間でいえば6,000円分もY!mobileならお得な恩恵が受けられるわけです。
The benefits of Yahoo! Premium members are mainly:
It is a very nice point to be free for premium members who can receive such benefits.This is especially recommended for those who often use Yahoo! Shopping and those who use Yahoo auction.
In cheap SIM carriers, it is often difficult to sell iPhone.
そのためY!mobileは、iPhoneの販売を行っている貴重な格安SIMキャリアといえます。せっかく契約するならiPhoneがほしい、iPhoneを欲しがる子どものために格安SIM＋iPhoneを購入したいと考えている方におすすめです。
As of November 2021, Y! Mobile handles the following iPhone:
Of course, the model price is also supported in installments.You can get a discount service and get a new iPhone with a real rate of 0 yen, so if you are looking for a cheap SIM where you can buy an iPhone, Y! Mobile is a career you should actively consider.
Application / transfer procedure for Y! Mobile
From now on, we will introduce a new application procedure from another company to Y! Mobile or new application procedure.
What you basically need when you transfer is:
The following is a valid identity verification document:
If the contractor is a minor, a document such as a statutory agent consent is also required.
If you do not buy a terminal with Y! Mobile in the Y! Mobile contract, you need to replace the SIM with the original smartphone or purchase a smartphone in another place.In that case, make sure that it is a corresponding terminal.
A model with an old release date may not be used because it does not support Y! Mobile or because the SIM lock has not been released.
そのため対応端末かどうかは、Y!mobileの動作確認済機種一覧で事前にしっかりと確認しましょう。また、SIMロック解除が必要な場合は、購入したキャリアでの手続きが必要になります。
When transferring and applying for a new one, we will first decide on the SIM type, plan, and option.
If you purchase a terminal, enter from the terminal purchase page, but if you use the smartphone you have used so far, select only the SIM contract.
If only SIM is contracted, make sure that the smartphone you plan to use corresponds to which type of SIM.You can check the SIM type size from the product information page of the purchased smartphone and the page of the Y! Mobile's SIM operation model.
Apply from the official website.
近くに店舗がある方は店舗からでも申し込みは可能ですが、オンラインのほうが契約事務手数料3,300円（税込）が無料となります。また、分割にあたっての頭金も0円となるため、基本的に購入時の費用負担なしで契約できます。
公式サイトから申し込んだ後は、送料無料でSIMカードや端末が自宅まで配送されてきます。受け取り後にAPN設定を行えば、ネット開通、課金開始となります。
The APN setting is a setting for catching the specified radio waves and performing data communication, and basically the setting is required when a cheap SIM transfer in the form of bringing in the terminal.If you skip this setting, you will not be able to grasp the Y! Mobile's radio waves, so you will not be able to communicate with data.Don't forget to check the instructions.
Y! Mobile optional information
Y! Mobile can be used even more by contracting options.We will look at the two types of call options and data increase options.
You can choose more than the following two options:
| オプション | だれとでも定額 | スーパーだれとでも定額（S） |

| 向いている人 | 毎月合計18分以上通話する 短い時間の通話が多い | 毎月合計43分以上通話する 通話時間を気にしたくない |
* All prices and fees are as of November 2021.
Y!mobileでは、2タイプの音声通話のかけ放題オプションが用意されています。
As the table is calculated based on the basic call fee (22 yen/30 seconds),
It is a great deal for those who use this way.If you frequently use calls, choose the option that suits you and use the phone at a better price.
Y! Mobile's monthly data capacity is 3GB, 15GB, and 25GB for each plan.
However, if you often exceed the data capacity, but not enough to contract for a high -ranking plan, it is recommended that you use an increase option that allows you to increase the communication capacity every month.
| プラン | シンプルS | シンプルM | シンプルL |
|---|---|---|---|
| 通常の通信容量 | 3GB | 15GB | 25GB |
| 増量オプションで追加される容量 | ＋2GB | ＋5GB | ＋5GB |
| 合計 | 5GB | 20GB | 30GB |
| 増量オプション 月額料金（税込） | 550円 | 550円 | 550円 |
* Information as of October 2021.
In the case of simple M / L, 5GB increases, so it is a nice point for those who use many apps and internet.
もちろん使わなかったデータの繰り越しも増量の対象となるため、使う月と使わない月のギャップが激しい方はよりお得になる可能性があります。
Y! Mobile's common questions
We will organize the points that you want to check and feel uneasy when using Y! Mobile.
Y!mobileは格安SIMですが、回線自体はSoftBankのものを利用しています。そのため回線エリアは、SoftBankがつながるエリアとなります。
SoftBank is one of the three major carriers alongside docomo and au.The line area is basically very wide and supports nationwide, and is connected in mountainous and underground.
That does not mean that it will always be associated.By the way, you can check the area map on the Y! Mobile official website for areas where Y! Mobile is connected, including 5G compatible areas.
Y Mobile Official Homepage | Area Map
The area map allows you to check not only the normal connection area and the 5G compatible area, but also the area that is connected at sea and water.You can also search for the region's name and keywords of municipalities.
The terminals that support Y! Mobile are as follows.
It is a smartphone that meets any of the above conditions.If you don't have a SIM lock or a SIM -free, you can basically use a smartphone purchased by other companies that are not Y! Mobile.
また、他社端末持ち込みの場合は、事前に 動作確認済み端末の一覧にその端末があるかを確認しておきましょう。
If you can confirm that there is a terminal in the list, you can see that the operation is confirmed on the Y! Mobile side, so you can use it with confidence.
Y!mobileではいつでもプラン変更が可能です。変更回数の制限もなく、手数料もかかりません。
If the data capacity is often exceeded early every month, you should consider using a higher plan.Conversely, if you only carry over and have too much capacity, you want to change to a lower plan.
It is possible in changes, online or stores, but since the change is monthly, if the change procedure is performed in the middle of the month, it will be applied from the following month.
There are two ways to change the model with Y! Mobile.
If you purchase with Y! Mobile, you can pay in installments by passing the examination.If you are online, the down payment at that time will be 0 yen, and the shipping fee will be free, so if you want to buy it at a great price, online is recommended.
Cancellation can be performed on the web or store.Especially on the web, you can do the procedure without waiting time.
また、Y!mobileでは、契約中のプランによって10,450円（税込）の解約金が発生するケースがあるため注意が必要です。
Basically, the cancellation fee is not the current plan as of the 11th of 2021, but the plan that was accepted in the past.Therefore, it is necessary to confirm whether the cancellation fee will be charged with the contract on My Page.
ちなみにY!mobileから他社へ乗り換えする場合のMNP転出手数料は無料です。
In Y! Mobile, the speed limit is subject to exceeding the data capacity for each plan.The speed after the limit is as follows.
| プラン | シンプルS | シンプルM | シンプルL |
|---|---|---|---|
| 通信容量 | 3GB | 15GB | 25GB |
| 容量超過後の速度 | 300kbps | 1Mbps | 1Mbps |
After the speed limit is applied, videos and music playback and the browser page of the Internet may be delayed.Of course, tethering is also slow.
However, there are opinions such as "Surprisingly slow" because a simple M / L plan can be high -speed communication with a maximum of 1 Mbps even after restriction.Especially if it is easy to grasp radio waves.
However, it is certain that it will be difficult to use if the speed limit is applied, so if the capacity is expected, we recommend that you consider a higher -level plan or a data increase option that can be used for 550 yen per month (tax included).。
summary
Y! Mobile is a cheap SIM but has a reputation for high -speed communication.In fact, highly evaluated and good reputation, such as "easy to connect" and "fast", is often seen on SNS.It is also attractive that it is a major carrier, SoftBank's sub brand.
When contracting a cheap SIM, it is important to be able to use it that suits you and check if it is really a great deal.Check out the reputation and advantages and disadvantages you have seen this time, and then consider whether to sign up for Y! Mobile.
