A Japanese number does not guarantee acceptance by every app or website. Some services reject VoIP, overseas or certain mobile-number ranges.
Choose the line by what you need
Answer all three questions to see what type of line to check.
What each SIM type can do
| Type | Calls | Incoming SMS | Typical use |
|---|---|---|---|
| Voice SIM | Yes | Yes | Appointments, callback number and verification |
| Data SIM with SMS | No | Yes | SMS and mobile data; not ordinary calls |
| Data-only SIM/eSIM | No | No | Internet apps; not an SMS verification line |
| VoIP app | In-app | Depends | Not treated as a normal mobile number by every service |
Check before paying

- Are incoming SMS included, and what do outgoing messages cost?
- Will the specific app or service accept this line?
- Can you meet its ID, address and payment requirements?
