Hi @IT Support, Starting November 1, 2022 sending and receiving international SMS and MMS messages will no longer be supported within RingCentral MVP. For more information about this, you may go to https://support.ringcentral.com/article-v2/impacts-to-international-sms.html?brand=ringcentral&product=mvp&language=en_us.

I know this is an old question, but answering it for new comers on this page. RingCentral supports SMS only on RC US and Canadian accounts/numbers. Outside of US and Canada, SMS service is not included (like in Australia under Global MVP license)
