RentalBest for re‑logins, password resets, and recovery. Keep access longer.
Simple ruleFree → Activation when blocked → Rental when you need continuity.

How it works

  • Pick country + copy the number
    Select your country, grab a number, and copy it exactly.

  • Request the OTP on Curve
    Enter the number on the Curve verification screen and tap Send code (avoid rapid retries).

  • Check PVAPins inbox
    Refresh once or twice, copy the OTP as soon as it arrives, and enter it immediately (codes expire fast).

  • If it fails, switch smart
    Don’t spam resend. Switch number/route, wait a bit, then try again once.

    Common Questions on Curve SMS in Japan

    1) Is using a virtual number allowed for Curve in Japan?

    Generally, yes, virtual numbers receive OTPs like a regular phone. Your responsibilities don’t change: always follow Curve’s terms and local regulations in Japan. PVAPins provides private delivery routes; how you use them must remain lawful and compliant.

    2) Temporary vs Rental, what should I choose for Curve?

    If you’re doing a one-time sign-up, a Temporary line is enough. If you expect re-logins, device changes, or multi-profile work, choose a Rental to keep the same identity and avoid reuse friction or repeated checks.

    3) What if the OTP is slow or never arrives?

    Wait for the full timer, resend once, then switch to a fresh line or nearby country corridor. Delivery delays are usually route-specific and short-lived. Rentals help maintain stable identity signals over time.

    4) Can one number be reused across multiple Curve accounts?

    Many platforms restrict reuse. For predictable results, dedicate one number per profile. Rentals make this easy and reduce cross-account conflicts or flags.

    5) Is a public/free inbox okay for Curve?

    Public numbers are heavily reused and often blocked. For accounts you care about, choose private PVAPins numbers for better deliverability, privacy, and long-term access.
