Why Voicemail Matters

Voicemail lets you screen unknown calls safely. If the caller has a real reason to reach you, they'll leave a message. You can then decide whether to call back, avoiding direct contact with scam or nuisance callers.

Types of Voicemail

Carrier voicemail services (NTT Docomo, au, SoftBank - about 330 yen/month) work even when your phone is off. iPhone's Visual Voicemail shows messages in a list you can tap to play.

Setup

iPhone: Phone app > Voicemail tab > Set Up Now. Android: Phone app > Settings > Voicemail. Requires a carrier voicemail subscription.

Recording Your Greeting

Don't say your name - scammers can use it. Keep it short (10-15 seconds). Ask callers to leave a message after the tone.

Using Voicemail as Scam Protection

Let unknown calls go to voicemail. Scammers rarely leave messages. No message = probably not important. This eliminates the risk of directly engaging with fraud callers.

Frequently Asked Questions

Is voicemail free?

Carrier voicemail services cost about 330 yen/month. Some budget SIM providers don't offer it. iPhone's Visual Voicemail works at no extra cost if you subscribe to your carrier's voicemail service.

Why shouldn't I say my name in my voicemail greeting?

Including your name lets scammers learn it. They can then call back using your name to sound legitimate, making you more likely to trust them. Use a generic greeting without your name.

Can I change the number of rings before voicemail picks up?

Yes, you can change it through your carrier's settings. For NTT Docomo, dial 1419 to adjust the ring time. Setting it to 3 rings (about 10 seconds) is recommended for nuisance call protection, as it switches to voicemail before you accidentally answer an unknown number.
