Democratizing
Telecom Knowledge
We are not a vendor. We are a volunteer collective of engineers, developers, and marketers dedicated to decoding the complex world of mobile messaging.
Who We Are
For decades, telecommunications knowledge has been locked behind expensive consulting fees, complex carrier documentation, and gated vendor portals.
WhatIsSMS.com was born from a simple frustration: "Why is it so hard to find clear, unbiased information about how SMS actually works?"
We are a group of volunteersÔÇösoftware architects, network engineers, and product managersÔÇöwho believe that communication infrastructure knowledge should be open source and accessible to everyone.
Volunteer Driven
No sales pitches. No hidden agendas. Just pure technical documentation and industry insights written by experts.
Open Knowledge
We break down protocols like SMPP, SS7, and RCS into understandable guides for developers and businesses.
Compliance Focused
Navigating 10DLC, TCPA, and GDPR is hard. We provide checklists to keep the ecosystem safe and spam-free.
Developer First
From character encoding to API integration patterns, we build the resources we wish we had when we started.
Join the Conversation
We are always looking for contributors, fact-checkers, and industry partners who share our vision of an open telecom ecosystem. Whether you want to correct a typo or propose a partnership, we're listening.
