How to Verify Sideline Without a SIM — Quick Setup in Bulgaria

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.

    • Bulgaria number format (quick copy)

    • Country code: +359
    • International prefix (dialing out locally): 00
    • Trunk prefix (local): 0 (drop it when using +359)
    • Mobile pattern (typical for OTP): mobiles typically start with 08 domestically (e.g., 08z…) → international becomes +359 8z…
    • Mobile length used in forms:9 digits after +359 (mobiles)

    Typical pattern (example):

    • Mobile (domestic): 088 123 4567 → International: +359 88 123 4567 (drop the leading 0)

    Quick tip: If the form rejects spaces/dashes, paste it as +359881234567 (digits only).
