The most useful feature is that it allows us to send SMS messages from our business phone line which would otherwise be blocked by mobile providers, so we can continue with work while travelling! I also like how easy-to use this tool was for my team at first glance - even non techies could manage their accounts without any problems or errors being reported afterwards! Some of its features are outdated (i think they need an upgrade) but not much you cannot fix yourself if needed too :) Definitely worth checking out as long your organization uses international numbers already!! It's definitely helped me reach new customers who don't have access to other communication channels through email/phone calls etc., giving them more options than just Whatsapp & Facebook Messenger only!
