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 in the app (Firebase Auth screen)
    Enter the number on the phone 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.

    • Cuba number format (quick copy)

    • Country code: +53
    • International prefix (dialing out locally): 00
    • Trunk prefix (local): 0 (used for domestic long-distance between area codes)
    • Mobile pattern (typical for OTP): mobile numbers are typically 5xxx xxxx (8 digits total)
    • Mobile length used in forms:8 digits after +53

    Typical pattern (example):

    • Mobile: 5123 4567 → International: +53 5123 4567

    Quick tip: If the form rejects spaces/dashes, paste it as +5351234567 (digits only).

    Why Use a Virtual Number for Firebase in Cuba?

    • Perfect if you need multiple accounts – Run more than one Firebase profile without juggling phones.

    • Super-fast delivery in Cuba – Codes usually arrive in seconds.

    • No SIM, no device drama – Everything’s managed online inside your PVAPins dashboard.

    ? Fun fact: A Statista report showed that over 60% of people worry about sharing their phone number online. Virtual numbers fix that problem in, well… one click.
