KEY DEVELOPMENTS ACROSS MESSAGING, IDENTITY AND AI
The regulatory landscape for mobile is changing rapidly. What does this mean for business?
Let me share some key areas of activity with examples from the UK and around the world.
Messaging & AntiFraud: SMS Sender ID Regulatory Activity
The most visible global regulatory shift affecting messaging is the rapid tightening of SMS Sender ID rules.
A major enforcement milestone
For example, from 1 July 2026, all branded sender IDs used in Australia must be registered in the national SMS Sender ID Register operated by ACMA. Unregistered IDs will be labelled “Unverified” or may be blocked, and international traffic must comply in the same way.
Implementation challenges become visible
Ireland’s SMS Sender ID Registry went live in July 2025, applying a “Likely Scam” label to unregistered alphanumeric IDs. A full blocking phase was scheduled for October 2025 but was postponed after integration issues among some service providers risked mislabelling legitimate traffic.
This illustrates the practical difficulty of implementing nationalscale identity controls across multiple operators, aggregators and brand owners.
A fragmented global landscape
The Mobile Ecosystem Forum conducts crosscountry monitoring which shows a lack of harmonisation. Several countries mandate sender ID registration (e.g., Greece, Italy, Romania, Finland, Ireland), others allow operators to enforce policies without a central registry (e.g., Belgium, Hungary), some recommend but do not require registration (e.g., Poland), and others still allow fully dynamic sender IDs (e.g., Malta, Lithuania). Outside Europe, Singapore, and Australia also adopted a full national registry model.
The trend for 2026 is clear: more countries are moving towards mandatory identity controls, tighter authentication of A2P traffic, and greater willingness to block unregistered sender IDs.
Connectivity & Wholesale
Directtodevice (D2D) satellite connectivity is one of the most significant developments — not because it is commercially mature, but because regulators have moved relatively quickly to create the right conditions for deployment. For example, by late 2025, the UK had completed its D2D regulatory framework and Ofcom has expressed an ambition to support commercial launches from early 2026, subject to industry readiness.
The challenges to massmarket rollout
Key constraints remain for widespread D2D adoption:
- Devices: Only a small number of handsets currently support D2Dcapable satellite waveforms.
- Functionality: Early deployments will likely enable only basic fallback messaging.
- Economics: Operators and satellite service providers must still define viable pricing models.
- Coverage and performance: Satellite links for massmarket devices require further realworld validation.
Authentication & Identity APIs: Age assurance moves into an enforcement phase
2026 marks a turning point in ageassurance regulation, with implications for APIdriven identity, mobilebased authentication and privacypreserving verification.
Stronger protections for minors
Under Australia’s Online Safety framework, platforms must prevent minors from accessing harmful content such as pornography or selfharm material and must implement secure ageverification or ageestimation mechanisms. Platforms must also prevent adult–child messaging by default in highrisk environments.
The UK’s Online Safety Act transitions from policy formation to implementation during 2026. Ofcom is issuing codes and guidance that require platforms to prevent children from accessing harmful content, enforce ageappropriate design measures and embed safetybydesign features into communication tools.
DCB, Content & Advertising: AI becomes a commercial interface
Advertising enters AI assistants
In 2026, OpenAI begins testing advertising inside ChatGPT for loggedin adults using the free tiers. Ads will be displayed at the bottom of chatbot answers, fully labelled, with no influence on model responses and not shown to minors. Paid tiers remain adfree, and users can turn off personalisation.
For the digital commerce and content community, this development signals that AI assistants may soon mediate discovery, recommendation and purchasing journeys. Transparency about commercial influence may become a regulatory expectation — especially when AImediated flows intersect with Direct Carrier Billing (DCB), subscription models or content purchases
Intellectual property and training data: a structural challenge
The debate surrounding the use of creative works for AI training is intensifying. At a recent FT event last November (2025) Ed NewtonRex, CEO of Fairly Trained, has described unlicensed AI training on creative works as “the greatest theft in the history of the industry,”.
The Swedish music rights society STIM has introduced what it describes as the world’s first collective AI licence – a marketled framework designed to balance innovation with fair remuneration and combat unauthorised AI training on copyrighted works.
For the content ecosystem, provenance, attribution and licensing models will become increasingly important as mobile content distribution intersects with AIgenerated media.
Final thought
Taken together, stronger antifraud protections, satelliteenabled mobile coverage, modernised identity frameworks and clear rules for AI’s influence will form the backbone of the 2026 regulatory agenda. Although these themes cut across sectors and technologies, they all reaffirm the same reality: mobile is the connective tissue of the digital economy, and its expanding role demands regulatory approaches that are both proportionate and timely.
