1. Check Your Internet Connection
The primary cause of Telegram code failures is poor connectivity.
Action Steps:
- Switch between Wi-Fi and mobile data.
- Restart your router or device.
- Ensure no VPN is blocking Telegram.
Example: Users on shared networks often face delayed SMS due to bandwidth congestion.
2. Confirm Your Phone Number
Incorrect or incomplete numbers prevent Telegram from sending codes.
Action Steps:

- Double-check for typos.
Case: An international user mistakenly used a local format, causing failed code delivery.
3. Update the Telegram App
Outdated apps can fail due to protocol changes.
Action Steps:
- Update Telegram via App Store or Google Play.
- Enable automatic updates.
- Clear cache after updating.
Scenario: Android users who skipped updates experienced recurring SMS delays.
4. Restart Your Device
Restarting can resolve temporary glitches affecting code reception.
Action Steps:
