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

Enter your mobile number.

Use a valid phone number that you personally control. For best results, enter it in international format: +CountryCodeNumber with no spaces, dashes, or extra leading zeros.

Select the correct country.

Choose your country and double-check the full number before submitting. Small formatting mistakes can cause verification to fail.

Request the OTP on Genspark.

Go to signup, login, or security verification and tap Send code. Avoid repeated or rapid requests.

Wait for the SMS code.

Allow 60–120 seconds for the OTP to arrive. If it doesn’t come, resend only once and ensure your network and number format are correct.

Enter the code quickly.

Copy the OTP from your SMS inbox and enter it back on Genspark immediately, as codes may expire quickly.

Japan number format (quick copy)

  • Country code: +81

  • International prefix (dialing out locally): 010

  • Trunk prefix (local): 0 (drop it when using +81)

  • Mobile pattern (common for OTP): mobiles typically start with 070 / 080 / 090 locally

  • Mobile length used in forms: usually 10 digits after +81 (because the leading 0 is removed)

Common pattern (example):

  • Mobile: 090-1234-5678 → International: +81 90 1234 5678 (drop the leading 0)

Quick tip: If the form rejects spaces/dashes, paste it as +819012345678 (digits only).
