I'm working on implementing a solution using SMS/MMS for communicating with end users via the Twilio service. All seems to be going well with this, but I was recently intrigued when I personally received a message via SMS (e.g., it came through the SMS messaging app on my mobile device) in a format that looks different than I'm used to seeing. Because the use-case for my project has to do with professional business communication, I really like the format and would like to see about replicating it for our outbound messages.
The only problem is that I'm not sure exactly what this format is in the first place. Is it a "specialized" SMS format? Is it a format used by another application like WhatsApp, or something that's capable of sending messages through the SMS system? I see the "verified" shield icon and I assume that would require some additional processes to achieve, but the rest of it - a message body that looks like something done with HTML, the "description" under the logo in the main body, the additional contact detail in the "Info & options" menu, the "masked" name for the sender - seems like it must be either buried in code or documentation that I probably just haven't been able to find yet.
