Is This Safe and Legal?

Yes. Using a virtual number for Signal verification is perfectly legal in most jurisdictions, including Japan. The number is a legitimate mobile line assigned to you temporarily. Signal’s terms allow using any number you can receive SMS on. We do not facilitate spam, fraud, or illegal activities. All purchases are final and non-refundable due to the digital nature, but our support team is available 24/7 to help with any issues.

How long does the Japanese number work for Signal?

The number is active for receiving SMS for 24 hours after your first message. After that, it expires, but the Signal account remains active unless you re-verify with a new number.

Can I use the same number for other services?

Yes, you can use the same Japanese number for any SMS verification during the 24-hour window. However, we recommend purchasing a dedicated number for each service to avoid conflicts.

What if I don't receive the SMS from Signal?

In rare cases, the code may be delayed up to 2 minutes. If you don’t receive it, contact our support via the live chat on the website – we will issue a replacement number or refund if the issue is on our end.
