SMS service boundary Establishes the intended meaning of SMS and the transport identity of each communication.

SMS sense and instance

Separates the registered concept from particular messages and messaging activities.

Interpretation of SMS

Record the evidence supporting Short Message Service as the intended registry sense and identify the unit being assessed.

  1. Does the registry intend Short Message Service, and what source establishes that expansion? definition
  2. Is the instance a logical SMS message, a transmitted segment, a sending event or a conversation containing SMS? boundary

Transport and fallback

Identifies SMS use when interfaces or providers expose several messaging services.

Transport evidence

Record how the transport was identified and whether fallback changed the service used.

  1. Which message metadata, provider record or device observation identifies this transmission as SMS? provenance
  2. Did this message switch between SMS and another service, and which model owns each transmission? boundary
SMS parties and routing Connects observed SMS addresses to intended parties and usable communication routes.

Origin and destination

Distinguishes addressing information from party identity.

Address-to-party binding

Record the sender and recipient address forms, their claimed owners and the freshness of verification.

  1. What originating and destination addresses are observed, and which people or organisations are they claimed to represent? definition
  2. What evidence links the destination to the intended recipient now, and could reassignment or shared access undermine that link? provenance

Reply and conversation

Determines whether an SMS can support a response and how it relates to prior messages.

Reply route validity

Record whether replies are supported and whether the apparent conversation corresponds to a verified route.

  1. Can this originating address receive a reply, and what evidence establishes where that reply will go? provenance
  2. Should the agent reply by SMS, use a separately verified contact route or leave the message unanswered? action
SMS payload and segments Tracks how intended message content becomes transmitted and received SMS segments.

Text representation

Assesses the relationship between composed content and its encoded representation.

Encoding and content fidelity

Record the selected encoding and any transformation affecting the intended text.

  1. Which encoding will the route use, and how does the actual text affect its estimated segment count? measurement
  2. Will any character substitution, truncation or provider transformation change a name, URL, code or instruction? boundary

Multipart integrity

Relates a logical message to its component segments and received assembly.

Segment completeness

Record expected and observed segments, their ordering and evidence that the logical message is complete.

  1. How many segments were expected, submitted and observed as received, and which are missing or duplicated? measurement
  2. If only part of the message is available, can its instruction be interpreted safely or must the agent seek the complete message? action
SMS delivery and recovery Interprets SMS status evidence and governs responses to delay, failure and uncertainty.

Delivery evidence

Preserves the meaning, source and timing of each reported lifecycle event.

Status semantics

Record provider status labels alongside their documented meanings and the conclusions they support.

  1. What does each observed status mean for this provider, and which system generated it? provenance
  2. Does the evidence establish acceptance, endpoint delivery or human acknowledgement, and what remains unobserved? boundary

Expiry, retry and fallback

Connects delivery uncertainty to message usefulness and duplicate risk.

Recovery decision

Record the useful lifetime of the content, retry history and authorised alternatives.

  1. When does this message become stale, and could a delayed delivery still prompt an incorrect action? measurement
  2. Given prior submissions and uncertain delivery, should the agent wait, retry, stop or use another authorised channel? action
SMS permission and trust Assesses whether an SMS may be sent or acted upon and how its content should be handled.

Purpose and recipient permission

Connects sending authority and recipient preferences to the particular communication.

Send and suppression basis

Record the purpose, applicable permission evidence and any request to stop relevant messages.

  1. What authorises this SMS to this recipient for this purpose, and where is that evidence recorded? provenance
  2. Does a withdrawal, suppression instruction or unresolved permission question require the agent to stop this send? action

Sensitive content and deception

Evaluates message handling and requested actions without assuming the displayed sender establishes trust.

Content handling and verification

Record sensitive payloads, suspicious requests and independent evidence needed before acting.

  1. Does the SMS contain an authentication code, private information, a link or a request for money or credentials that changes how it should be handled? boundary
  2. Before following its instructions or disclosing its contents, what independent verification or explicit authority does the agent need? action
Evidence and external alignment What the world already says about this thing, gathered so the model can be checked against it.

What it is Filled

SMS (Short Message Service) is a standardized telecommunications service for exchanging short text and other limited payloads between mobile subscribers and service applications, using network infrastructure that supports store-and-forward delivery.

In scope

  • Identification of a communication as SMS and its relationship to a wider conversation
  • Sender identity, recipient addressing and reply routing
  • Message content, encoding, segmentation and reassembly
  • Submission, delivery evidence, failure, expiry and retry decisions
  • Purpose, recipient permission, sensitive content and abuse handling

Out of scope

  • MMS, RCS, email and internet messaging services beyond their boundaries with SMS
  • Mobile network infrastructure and telecommunications protocol implementation
  • Handset hardware and messaging application design
  • Marketing campaign strategy beyond the handling of individual SMS communications
  • Authentication systems beyond the role and handling of an SMS message
  • Other expansions of the acronym SMS

Why it exists Filled

Enable an AI agent to recognise an SMS communication, assess its delivery and handling state, and determine which messaging actions are appropriate.

Distinguishing features Filled

  • Identify SMS through transport or provider evidence; a short text or chat-style interface alone does not establish that the communication is SMS.
  • Distinguish the user-visible message from its transmitted segments and determine whether several segments represent one logical message.
  • Separate submission acceptance, delivery evidence and evidence of human reading; one state must not be substituted for another.
  • Distinguish an originating address or displayed sender label from a verified person or organisation.
  • Identify when a messaging application changes transport between SMS and another service, even within the same conversation.

What robots and AI may and may not do Filled

Must not

  • Send bulk or marketing SMS without the recipients' consent.
  • Send messages that impersonate banks, authorities or other senders.
  • Read or forward someone else's SMS without their consent or a lawful order.
  • Rely on SMS one-time codes as strong protection where it is known to be weak.

Only with a human decision

  • Sending messages to many recipients at once.
  • Sending messages on someone's behalf that commit them to anything.

May

  • Send SMS messages on a user's instruction to recipients who have agreed to receive them.
  • Report delivery status and errors for messages it sent.

Moral aspects Filled

  • SMS is a main vector for fraud and phishing.
  • Messages hold private content and reveal who talks to whom.

Who is affected

  • Mobile users
  • Elderly people targeted by scams
  • Recipients of bulk messages

Owners Filled

Steward

The sender for the message; the mobile operator for the network service.

Master systems

  • Mobile network subscriber records

Open questions

  • Does vr.tr.sms mean Short Message Service, an individual SMS message or another expansion, and how should its ACT placement constrain ownership?
  • Does an existing Vercy world model already cover SMS or mobile messaging, requiring this entry to link to that model?
  • Which authoritative specifications and provider documents should establish encoding, segment limits, supported payload types and delivery-status semantics?
  • Should binary or application-directed SMS be included in this model, or does the intended registry scope cover only human-readable messaging?
  • Which jurisdictional, provider and organisational requirements apply to permission, sender identification, retention and suppression for the intended uses?
