Because Y!mobile is an MVNO (mobile virtual network operator) provided by SoftBank, it uses the same mobile network and has the same coverage. This means that the stability and connectivity of Y!mobile are almost the same as SoftBank’s.

There are 3 main plans that they offer, 3 GB, 15 GB, and 25 GB. If you aren’t looking for a large amount or unlimited data, then signing up for Y!mobile could be a great way to save some money on your monthly plan without sacrificing speed or coverage.

English support is limited, but they do have some stores on U.S. military bases that have English-speaking staff! If you need English support and have access to a U.S. military base, consider making a contract at one of their stores.

If you’re looking for English support

Consider checking out Sakura Mobile, a Japanese phone service provider with full English customer support.

2. Pros of Y!mobile

2. Pros of Y!mobile

Y!mobile has various advantages compared not only to the larger carriers but also to other MVNOs (mobile virtual network operators). For example….

Lower rates than SoftBank

The plans that are offered by Y!mobile are cheaper than the ones that are offered by their large carrier counterpart, SoftBank. SoftBank’s Mini Fit Plan Plus costs 5,478 JPY for 3GB, but Y!mobile’s Simple S plan is 2,178 JPY for 3GB. If you aren’t looking for unlimited data, Y!mobile will help you save money every month.

Translation
Changed from SoftBank to Y!mobile! I lowered my monthly phone bill by 3,000 JPY even including the fee for a new phone, and also lowered the monthly fee on my internet by 3,000 JPY.
ヽ(=´▽`=)ノ I got cashback for the cancellation fee and also got a 3,000 JPY gift certificate for the replacement fee, so I paid only 300 JPY for the replacement ☺ nothing but good things lol.

Fast speeds

Y!mobile has a great reputation for its speeds. There are many good comments on Y!mobile’s communication speed, including many that compare it to other companies. It’s a service that is faster than other low-cost smartphones.

Translation
Y!mobile is so fast, I think this might be the first time I’ve had 4G speeds over 100Mbps.

You can save money while Yahoo! Shopping

Many Y!mobile users have talked about something that is kind of surprising but super convenient and beneficial. The fact that Y!mobile users have the privilege of becoming Yahoo! Premium members for free, which costs 508 JPY per month (tax included). There are also various cash-back rewards and coupons that you can get! Users who shop online a lot seem to appreciate it.

Translation
The Yahoo Premium membership and Yahoo Shopping cash-back rate increase that came with Y!mobile is more convenient than I expected, and I’d say that’s mostly why I’m sticking with Y!mobile. I don’t have any problems with the service quality either.

Many store locations

One of the unique features of Y!mobile is that you can also sign up for a smartphone or a low-cost SIM and consult with the support staff at a physical store and not just online. If you have any questions or any problems with your data, just pop into one of their many store locations. Note, however, that most stores do not have English-speaking staff.

Translation
I’m sure with Y!mobile you’ll have all the peace of mind you need with all of the stores they have!
They offer an internet set that has a monthly discount and family discount where the second line is cheaper, that’s what makes it different from UQ mobile!

3. Cons of Y!mobile

3. Cons of Y!mobile

Some readers may be thinking that Y!mobile seems like a good fit for them and that’s okay! But there are also a few cons that come along when signing up for a service like Y!mobile.

Limited English support

Y!mobile has limited English-language support. They have an English website, but it only explains the plans, and the online application process is only in Japanese.

In addition, after signing a contract, checking the contents of your plan, changing your contract, contacting the company in case of any problems (e-mail, phone, etc.), and any other customer support service will be in Japanese.

Unfortunately, the number of stores that have English-speaking staff is very small.

If Japanese is not your strong suit, we can’t recommend Y!mobile!

There are cheaper SIM plans

Y!mobile has one of the cheapest plans in Japan, but it’s not the cheapest. For example, Rakuten Mobile is cheaper than Y!mobile. There are plenty of cheaper service providers out there, so if cost is your number one concern be sure to check out other carriers. One thing to note is that other cheaper carriers cut costs on their end, so English support is rare and connection speeds may be slow and unstable.

Translation
Y!mobile is more expensive than the other cheap ones.
I’ll either go with Rakuten’s zero yen or UQ’s smallest plan, which is cheaper.

Bad customer support

Even though there are a lot of store locations, Y!mobile has a reputation for having poor customer service. Many reviews have said that they have had to wait for long periods of time to be helped, and some have even had to wait several hours during busy times. Their customer service support desk may also be difficult to reach during peak hours and during different times of the year. They tend to get busy when new smartphone models become available.

Translation
In my personal opinion, the clerk at Y!mobile was so incompetent and unfriendly that I think I’d sell better if I were the clerk, so I went to docomo and it was great and Poinco(docomo’s character) is so cute, so I’m switching to docomo and will go straight to Ahomo or Ahamo(one of docomo’s plans) in March, Poinco is seriously cute!
Goodbye SoftBank!
