@8ightvibes,

I totally get how frustrating this can be. Here’s some pointers on how you could solve this one:

Double-check your phone number: Make sure you entered the correct phone number, including the country code. Sometimes a small typo can cause registration issues.

Carrier compatibility: Some carriers might not be supported by Klaviyo. You can check Klaviyo's documentation or contact your carrier to ensure they support the necessary messaging protocols.

Clear cache and cookies: Sometimes, browser issues can cause problems. Clear your cache and cookies or try using a different browser. (You’d be surprised how often this is the case.)

Reattempt registration:

• Go to your Klaviyo account settings.
• Navigate to the SMS section.
• Remove the existing number and re-enter it.
• Follow the prompts to re-register your number.

Hope this helps :)
