I am trying to setup MFA with my Mexico mobile number, from a different country, I used the dial code and entered the full mobile number but it says invalid mobile number.
But in my dashboard I see that in the sms charges section Mexico is listed with a price per sms

Thank you for sharing the details of your issue, rixhy! Here’s a summary for the support team and a few suggestions to help troubleshoot:

Issue Summary

  • SDK: Web3Auth Plug n Play (PnP)
  • Platform: iOS (assumed from context and documentation references)
  • Feature: MFA setup with SMS (using a Mexico mobile number)
  • Problem: When entering a Mexico mobile number (with the correct dial code) from a different country, the system returns “invalid mobile number”.

Details Provided

  • You are using the correct international dial code.
  • The mobile number is entered in full international format.
  • The issue occurs during MFA setup (likely via enableMFA or manageMFA).

Next Steps & Suggestions

  1. Phone Number Format:
    Web3Auth expects the phone number in the format +{country_code}-{phone_number} (e.g., +52-XXXXXXXXXX for Mexico).

    • Please double-check that you’re using a hyphen (-) and not a space or other separator.
    • Example: +52-1234567890

  2. Country Restrictions:

    • Some SMS providers may restrict sending OTPs to certain countries or from certain regions.
    • Are you able to try the same number from within Mexico, or with a different network connection (VPN set to Mexico)?

  3. SDK Version:

    • If possible, please confirm the exact version of the PnP iOS SDK you are using. This helps check for any known bugs or updates.

  4. Code Snippet (Optional):

    • If you’re invoking MFA setup programmatically, sharing the relevant code snippet (how you call enableMFA or login with SMS_PASSWORDLESS) can help us spot any formatting or parameter issues.

  5. Console Logs/Screenshots (Optional):

    • If there’s an error message or stack trace in your Xcode console or browser, a screenshot or log excerpt would be helpful.

Documentation Reference

Please confirm:

  • The exact format you used for the phone number (e.g., +52-1234567890)
  • SDK version if you know it
