GSMA on RCS, encryption and the future of operator messaging

We include this as syndicated rather than original because the substance belongs to the GSMA, the global association of mobile operators. The useful thing we can do is point to it accurately, explain what it covers, and show how to read it, rather than restate it.

Business text messaging (often called A2P, "application-to-person") works because almost everyone has a mobile number. The GSMA's The Mobile Economy 2026 report counts about 5.8 billion unique mobile subscribers, roughly 70% of the world's population, and estimates that mobile technologies and services generated US$7.6 trillion of economic value in 2025, about 6.4% of global GDP. The same organisation develops RCS, the operator-run upgrade to SMS. If you are deciding how much to invest in operator messaging (SMS and RCS) versus messaging apps, these primary sources are where the facts start. Much of what is written elsewhere is a summary of a summary.

A great deal of trade-press coverage of RCS traces back to a handful of GSMA announcements, often via a vendor's summary of them. The restatements accumulate errors, particularly about what has shipped versus what has been specified.

The GSMA's own newsroom is where the difference between "the profile defines this" and "operators have deployed this" is stated most precisely.

The standards body's announcements describe capability that has been specified. That is a different claim from availability in a given market, which depends on operator deployment, and different again from business-messaging availability, which is a further gate.

When a vendor cites a GSMA release as evidence that a feature is available to you, that is three steps of inference compressed into one sentence. The primary source is where you can see the steps.

Operator figures also have a boundary. Traffic that never touches an operator's messaging network (WhatsApp, in-app chat and other "over-the-top" services) is outside them. That traffic is a large part of the picture for many buyers, and its absence is a boundary decision, not an oversight. Read operator figures and app figures from their own sources, and do not add them together: they count different things and the overlap is undefined.

We have no relationship with the GSMA and no interest in RCS succeeding or failing. We link to it because it is the authoritative account of a standard that a large share of business messaging may run on, and because secondary coverage is unusually unreliable.

Go to the primary source. Note the counting unit, who is counted, and the boundary. Separate "specified" from "deployed" from "available for business messages in my market". Take the multi-year direction rather than the single-year level. And read operator-carried and over-the-top volumes as two separate accounts of the world, because that is what they are.
