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 Sideline
    Enter the number on the Sideline verification screen and tap Send code (avoid rapid retries).

  • Check PVAPins inbox
    Refresh once or twice, copy the OTP as soon as it appears, 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.

    Top Benefits of Using a Virtual Number for Sideline in Sao Tome and Principe

    • Protect privacy by keeping your personal SIM off forms, apps, and databases.
    • Reduce failed attempts with fresh lines optimized for one-time passwords (OTPs).
    • Verify from any device that there are no roaming fees and no physical SIM swaps are required.
    • Fast routing helps codes land in seconds under typical network conditions.
    • Choose temporary or rental numbers based on how often you re-login.
    • Transparent pricing with pay-as-you-go control and no long commitments.

    Costs & Rental Plans in Sao Tome and Principe (Transparent Rates)

    PVAPins keeps pricing simple. Temporary numbers are best for one-off activations: you pay once, trigger the OTP, and you’re done. Rental numbers are suitable for longer projects and frequent logins; they keep the same line tied to your account to avoid future issues. Rates are shown upfront per app and country, with no hidden fees. For heavy use, monthly rentals typically reduce cost per verification and save time when re-verifying after device changes or security prompts. Start temporary if you like; upgrade to a rental later when you need predictable re-logins.
