When something goes wrong, you don’t know where to contact.
On social media, I also see comments like “I can’t call them directly” and “It’s all AI guidance and I never reach a person.” I can’t verify individual posts, so I’m only mentioning this as a tendency.
This article sorts out the channels confirmed on the official support page. It is based on what was written as of October 8, 2026.
One thing up front: this site uses Rakuten Mobile referral links. I’ll write about the inconvenient points as they are.
Bottom line: start with “Troubleshooting Navi,” and go to a channel if that doesn’t solve it
The official support page follows this flow.
- Solve it yourself: search Troubleshooting Navi (トラブル解決ナビ), the FAQ and the community
- If that doesn’t solve it: channels such as chat and phone
Rather than looking for a phone number from the start, entering through the page for your type of problem will probably get you there faster (my own view).

How to proceed by situation
From here on, this is my general advice.
Weak signal or can’t connect
Isolate the problem on your own device first, then contact support. The steps are in this article. Checking whether it’s an outage is covered in this one, and the official request form for when the signal is weak in a certain place is covered in this one.
You lost your phone
The official entry point is “Theft and loss.” Take steps such as temporarily suspending the line early. Steps for foreign residents are in this article.
Call problems
The conditions for Rakuten Link and the cases where calls are not free are sorted out in this article.
Things that help the process if you prepare them before contacting support
- Symptoms (since when, where, what happens)
- What you’ve tried (restart, reinserting the SIM, etc.)
- The account holder’s information and your device model
Summary
- On the official page, self-help options such as Troubleshooting Navi come first, and you move on to channels such as chat and phone if those don’t solve it
- Phone numbers and hours for the channels are not written in the body of the support page. You enter from each page
- Entry points to information pages are provided for each type of problem
- The Telecommunications Carriers Association (TCA) also exists as an external consultation service
How channels work and their hours can change. When you’re in trouble, check the latest guidance on the official support page.
