Hello @Gearup,
Welcome to the Klaviyo Community!
Unfortunately, you would not be able to use Klaviyo’s SMS feature in countries/regions we don’t support SMS. You can find a list of countries that Klaviyo supports SMS from our Where is Klaviyo SMS available? Help Center article.
If you wanted to send SMS to customers in a region that’s not supported by Klaviyo, you’ll actually want to use a separate SMS service provider.
Although Klaviyo’s support for SMS is only limited to select regions, we are expanding this feature globally. You can expect announcements both within the platform and via email whenever new regions become available.
Thanks for being a part of our Klaviyo Community!
David
