Free vs Activation vs Rental (what to choose)

Free (public inbox)Good for quick tests. Higher block risk because numbers are reused.
Activation (one-time)Better OTP success for verification flows. Use when success matters.
RentalBest for re‑logins, password resets, and recovery. Keep access longer.
Simple ruleFree → Activation when blocked → Rental when you need continuity.

How it works

  • Choose your number type
    Free inbox = quick tests. Activation or Rental = typically better delivery and fewer rejections.

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

  • Request the OTP on Cathay
    Enter the number on the Cathay 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 once again.

    • Vietnam number format (quick copy)

    Country code: +84
    Typical mobile format: +84 3X XXX XXXX / +84 5X XXX XXXX / +84 7X XXX XXXX / +84 8X XXX XXXX / +84 9X XXX XXXX

    Big tip (this is the one people mess up): Vietnam mobile numbers often start with a 0 locally.
    For international/OTP forms, you usually remove that 0 and use +84.

    Example:

    • Local: 091 234 5678

    • International: +84 91 234 5678

    • No-spaces version (when forms are strict): +84912345678

    If a site rejects your number, check these fast:

    • Don’t do +8409… (that extra 0 breaks it)

    • If the form doesn’t like spaces, paste it as +84XXXXXXXXX
