Channel · rank 10 of 100

SMS

Short text messages to and from a phone, with the cost known before sending and STOP always respected.

What it is

Text messages still reach almost every phone. A company uses them for reminders and short replies.

Two things matter: knowing what a message costs before it is sent, and stopping at once when the recipient answers STOP.

Why it matters

  • Rank 10 of 100 in the TrooIDs channel ranking, with a score of 3.7125.
  • One model put it at 80% or more of companies, the other at 70 to 80%.
  • When an AI agent runs this channel, both models agreed it also does the work of: delivery and read feedback for messages.
  • See how the ranking works.

What TrooIDs built

SMS reminders and replies, built and tested in a lab with test numbers:

  • the cost is known before sending: the channel counts how many message parts a text needs, character by character;
  • a reply is accepted only when the provider signed it, so a forged STOP is ignored;
  • STOP blocks the next message and START opens the channel again.

Proof status, in three parts

  • Live on this site: you can check it on trooids.com now.
  • Fixture: built and tested with sample data on our test copy of the site; it is not running on trooids.com.
  • Architecture: designed or required, not built here yet. Items marked "Owed" are still to do.

Live on this site

  • TrooIDs has an SMS number since 29 October 2026: +31 97 010 268 175, a Dutch mobile number, connected to trooids.com.
  • First live tests, 29 October 2026: the first SMS from trooids.com, sent minutes after the number was activated, never arrived; the second, at 21:22, reached the test phone within a minute. A STOP sent to the number through the provider arrived on trooids.com with the provider's signature checked, and was recorded as a stop.
  • A reply from an ordinary phone, 30 October 2026: an SMS sent at 14:37 from a prepaid phone (our test phone) to the number reached trooids.com within ten seconds. Since then the number is on the contact page.
  • Two rules learned from that test are now enforced: a text with a web link is refused before sending (the provider blocks links in SMS to Dutch numbers), and the cost shown before sending is the measured EUR 0.17 per message part.

Fixture

  • The lab build above: 5 of 5 checks passed (49 cases, 21 October 2026); 59 of 59 build obligations met (status 28 October 2026).

Architecture

  • Not used: a sender name instead of a number, because nobody could reply STOP to it.
