Why Am I Not Receiving SMS Verification Codes?

Introduction

This article explains what to do if you have enabled SMS Authentication on Coinlocally but are not receiving SMS verification codes. These steps help you troubleshoot common issues and ensure you can complete your login or security actions smoothly.

Steps to fix SMS code delivery issues

1. Check WhatsApp fallback

If you don’t receive the SMS code on your first attempt, the system will automatically send the verification code to your WhatsApp on your next attempt.

2. Clear your SMS inbox

A full inbox may prevent new messages from arriving. Delete old messages and try again.

3. Disable blocking apps

Turn off any apps that might block incoming messages, such as:

• Anti‑virus apps
• Firewall apps
• Call/SMS blocker apps

These may interfere with receiving verification codes.

4. Restart your device

A simple restart can refresh your network connection and fix temporary delivery issues.

5. Contact support if the issue continues

If none of the steps above resolve the problem, reach out to us via 24/7 Live Chat or submit a Support Ticket.

Additional notes

• Some mobile carriers may delay or block automated SMS messages.
• Using WhatsApp as a fallback often resolves delivery issues quickly.
• If your phone number continues to fail, you can request phone number deactivation through Support so you can register a new number.

Common Issues

• SMS blocked by carrier or device settings
• Inbox full
• Using a number that cannot receive international messages
• Security apps blocking Coinlocally’s SMS sender ID
