A woman looking frustrated while checking her phone in a busy street in Japan, representing the potential signal and coverage disadvantages of using Rakuten Mobile.

While the Rakuten SAIKYO Plan has many benefits, there are some downisdes to consider.

  1. Limited English Support: Rakuten Mobile has some customer support in English, but it is not a full-time service. This can be frustrating if you do not speak Japanese and need help with your plan.
  2. Signal Strength and Coverage: Some users have said that Rakuten’s signal can be unrelaible. This is especially true in rural areas, on subways, and inside some buildings. You might find that your connection drops often.
  3. Data Usage Limits: Even though the plan is “unlimited,” it still subject to Japan’s Fair Usage Policy. This means that yuor speed may be slowed down durin gpeak hours (like rush hour) to make sure everyone gets good service.
  4. You Have to Use the Rakuten Link App: To get free calls within Japan, you must use the Rakuten Link app. This can be annoying because it means you cannot use your phone’s regular calling app.

Sakura Mobile solves these problems by offering full English support and reliable service on the docomo network. Our plans are straightforward, with no hidden limits or special apps needed. You get a consistent signal and a team that can help you in english whenever you need it.

6. Who Benefits from Rakuten Mobile and Who Does Not

Who This Plan is For

The Rakuten SAIKYO Plan is an excellent fit for some people but not for everyone. The plan works best for those who:

  • Need a lot of data: With almost unlimited data for a low monthly fee, this plan is ideal for individuals who stream videos, play games, or use their phone extensively for work.
  • Do not need a lot of data: The pricing is teired, so if you use less than 3 GB of data in a month, you only pay a small fee. This structure makes it a flexible and affordable option for those who do not use thier phone much.
  • Use the Rakuten ecosystem: If you shop on Rakuten Ichiba or use other Rakuten srvices, you can earn and use Rakuten POints to get discounts on your phone bill.

Who This Plan is Not For

On the other hand, the plan may not be a good fit for people who:

  • Do not speak Japanese: While Rakuten has some English support, it is very limited. The language barrier can make it difficult to get help with your account, especially if you have an issue that is not covered in the English FAQs.
  • Need a very reliable connection: The signal can be inconsistent in rural areas, on subways, and in some buildings. If you need a strong, stable connection at all times, this might not be the best choice for you.
  • Want a simple, hassle-free experience: The need to use a separate app for free class and the complex pricing structure can be confusing.

Sakura Mobile is a better option for those who need a consistent and reliable connection without the hassle. We use the docomo network, which has excellent coverage. Plus, we offer full English support, from the application prociess to customer service, so you never have to worry about a language barrier.

8. English Support

When you live or travel in Japan, having customer support in a language you can understand is a big deal. Rakuten Mobile does offer some help in English, but it is limited.

You can visit their stores in person, where they offer ENglish application forms and a “Point-and-Speak” sheet to help you commumicate. They also ahve a limited English phone service. However, it often requires a three-way call with you, a customer service agent, and a phone interpreter, which can be time-consuming and frustrating.

Sakura Mobile is different. We provide comprehensive English support every step of the way—on our website, via email, phone, or in person. From the application to customer service, you can talk to someone in English without a language barrier. This can make your life much easier and less stressful.
