I'm putting my review here as well (has more details):

Okay, first I'm a noob with SMS services.
I have never used Twilio (but I've been registered for a year or two). But have always wanted to be able to use an SMS service. I'm an odd duck and always wanna try something other than the mainstream services/tools ("Stay weird," Sumolings! :'p)

So this is awesome. A Twilio replacement. And it's not just SMS. It's got e-mail and voice. And 2-way messaging :'o For several platforms... WhatsApp, Messenger, et al.

Just a short list of what I'm excited about here (these were mostly in the comments or Q&A section):
-Not limited to SMS (has email, chat services like Messenger) :'o
-Add unlimited numbers
-Send unlimited messages
-Send messages to all countries :'o (https://appsumo.com/products/sms-it-decentralized/#q832010)
-Does not need Twilio or similar platform (it's a standalone alternative/competitor)
-Does not need a SIM card :'o
-SMS rates cheaper than Twilio

I wanna use this for personal stuff as well. In fact I went outside today and bought a roaming SIM for the Philippines because I needed a Philippine number. See, I registered for Internet service for my parents in the Philippines and I had to pay online. Turns out, my credit/debit cards don't work there. It's mind-bogglingly lame. So I had to register for a Payment service there that requires a local-Philippine number.

I hope this helps someone. 🤟🖖✌️
