1. Make sure your WhatsApp account is linked to the same phone number as your CoinEx account.
2. Visit CoinEx's official website (https://www.coinex.com), log in to your account, and select [Preferences] from the dropdown menu under the [Avatar] icon in the top-right corner.
3. On the Preference page, find [SMS Code] and keep it turned off by default.
Notes:
- If you need to receive codes via third-party platforms like WhatsApp, keep the button disabled.
- If you only want to receive codes via SMS, keep the button enabled.
4. When obtaining the verification code, you can check your WhatsApp for the SMS code.
Note: If you're unable to receive the SMS code via WhatsApp, it may be due to your region only supporting SMS for receiving codes. If you have any questions, please submit a ticket for further assistance.
