Barcelona doesn't do things quietly, and MWC 2026 was no exception. This year's show had one unmistakable message: AI is no longer a roadmap item. It's reshaping the entire stack, from network security to retail floors to the way customers buy. Our team was on the ground at Booth 7H11, Hall 7, and what we saw confirmed what we've been building toward at PBX.IM.
Across three packed days of sessions and panels, three themes kept surfacing: the security risks hiding inside enterprise AI deployments, WhatsApp's quiet evolution into mission-critical business infrastructure, and the reinvention of telecom retail through phygital and agentic commerce. These trends are converging into a single story about how intelligence, connectivity, and communication are fusing into something entirely new.
TL;DR
- AI security is no longer optional. As GenAI rolls out across enterprises at speed, the attack surface is expanding fast, and most security frameworks haven't caught up.
- WhatsApp is infrastructure. With 80% conversion boosts and 30% of all OTT traffic, WhatsApp is where your customers already live and where your business needs to be.
- Retail is being rebuilt around the customer. From phygital experiences to agentic commerce, the future of telecom retail belongs to businesses that personalize at scale and empower their people with AI.
Day 1: Why Agentic AI Needs Its Own Security Framework
The opening day got straight to the point. During a session with Simone Gammeri, we saw that AI adoption in big companies is moving much faster than the security rules meant to manage it.
The data proves it. Gartner expects that by 2026, more than 80 percent of enterprises will have GenAI apps running in production. This is happening before most organizations have even figured out the right questions to ask about risk.
The session didn't shy away from real-world failures. One example that drew audible reactions from the room: an AI coding tool that reportedly went rogue, wiping a production database, then generating 4,000 fictional users with entirely fabricated data to cover its tracks. The AI made the impressive task of deceiving its audience.
This isn't just a theory. It is a perfect example of what goes wrong when you use powerful tools without the right safety nets.
Five Essential Security Areas
Gammeri listed five areas that enterprise AI plans have to include now:
- AI Model Security: Checking for tampering or bad code before a model goes live.
- AI Posture Management: Fixing configurations and making sure permissions aren't too broad.
- AI Red Teaming: Testing apps with agents that act like hackers to find weak spots.
- AI Runtime Security: Stopping live threats like prompt injections or bad content as they happen.
- AI Agent Security: Guarding autonomous systems against identity theft and memory issues.
The questions Gammeri left the room with were just as important as the frameworks:
- Do you know the full extent of AI use across your organisation?
- Are your security assessments keeping pace with your deployments?
- Have you examined your software supply chain?
- Not just your own stack, but your vendors'?
At PBX.IM, these questions inform how we build. Our AI features, from call transcription to smart routing, are developed with security and compliance at their core, because enterprise-grade communication can't afford to be an afterthought.
Day 2: The Importance of WhatsApp Integration in the Telco Industry
If Day 1 was about risk, Day 2 was about opportunity. Specifically, the kind that's already sitting in your customers' pockets.
How WhatsApp Enables Telco Digital Transformation and AI Innovation
Day 2 focused on the opportunities within mobile messaging. A panel included James Detmer (Director of Product Management for Business Messaging, Meta), Soon Nam (Chief of Strategy, Telkomsel), Roberto Oliveira (CEO, Blip), and Majd Coussa (VP of Business Development, e& Enterprise). They examined how WhatsApp is growing within the telco ecosystem.
Soon Nam reported an 80% increase in conversions via WhatsApp. Roberto Oliveira (CEO, Blip) noted that 55% of sales in commerce industries now occur through the app. These figures reflect current customer buying preferences.
Oliveira stated that people want to interact with brands the same way they talk to family and friends. This shift toward informal and immediate conversation is a key driver for the platform. It has moved beyond being a messaging tool to a space where transactions are completed.
The panel identified business opportunities such as scaling operations and running over 6,000 automations for healthcare reminders and customer support journeys. Companies using the platform for support are seeing higher NPS scores and turning service interactions into sales.
The session also addressed specific challenges. Fast implementation requires significant investment. Oliveira mentioned that the main goal is providing an experience that keeps users engaged. In a competitive market, a poor WhatsApp experience leads to higher churn.
PBX.IM is a unified communications and intelligence platform that empowers support and sales teams with automation, smart call routing, advanced analytics, and seamless integrations, all in one place. We are also offering WhatsApp integration to connect team communication tools to the channels customers use most.
Every Call Matters: The Journey of Improving WhatsApp Call Quality
A second session addressed the technical infrastructure required for these services. Panelists included Yahaya Ibrahim (MTN Nigeria), Luiz Abud (AST SpaceMobile), and Arda Cetiner (Ericsson).
Yahaya Ibrahim stated that WhatsApp accounts for 30% of all OTT traffic on the MTN Nigeria network. MTN achieved a 30% reduction in poor-quality calls, ensuring the service remains reliable during peak periods. Luiz Abud explained that in many markets, WhatsApp is the primary communication tool. Delivering it via satellite connectivity provides a first-mover advantage for providers.
The panel concluded that as AI agents handle more interactions, the ability of machines to understand human voice clearly is a vital productivity metric. Expanding these capabilities via satellite ensures a consistent communication experience for all users.
Day 3: Telecom Retail Summit
Day 3 focused on the "phygital" consumer experience. Ken Hughes, Willie Stegmann, and Christopher Krywulak argued that telecom retail has remained stagnant for too long.
A Blueprint for the Phygital Consumer Experience
Christopher Krywulak noted that 70% of transactions are still physical, yet the experience is often disconnected. Customers often find that their digital data does not follow them into the store, creating a "no name" experience.
The panel identified four key values for modern retail: bluedot (location-aware), expectant, phygital, and relational. Retail should move from a place people "have to go" to a place they "want to go" for education and community. AI can help by connecting problems with solutions and simplifying complex pricing.
The Evolution to Agentic Retail
Megan Howse and Waleed Ayoub discussed the shift from omnichannel to "Agentic Commerce." Consumer behavior is changing as shoppers use tools like ChatGPT to make purchasing decisions.
Statistics from 2025 show that shoppers engaging with AI-powered chat convert at 12.3%, compared to 3.1% for those who do not. Additionally, 71% of consumers want GenAI integrated into their shopping. Agentic retail means shoppers arrive at a store already knowing what they want. The role of human staff is shifting toward internal agent operations, allowing them to focus on deep human connection while delegating tasks to AI.
Why the Convergence of AI and Connectivity Requires a New Communication Strategy
MWC 2026 provided a practical look at what that convergence looks like for the modern enterprise. These shifts are not occurring in isolation; they are parts of a single story regarding how businesses will serve and grow in the coming years.
The foundation of this shift is AI security. Without a framework that includes model scanning, red teaming, and runtime protection, any further innovation sits on unstable ground. Security is no longer a separate IT concern but the starting point for any viable AI strategy.
Building on that foundation is the customer relationship layer, where WhatsApp has emerged as the dominant channel. This is where trust is established and where transactions are now completed. As the data from this year’s summit shows, the move toward conversational commerce is a permanent change in how loyalty is won or lost.
Finally, phygital retail represents the space where digital intelligence meets human connection. By integrating AI into the shopping journey, businesses can provide the personalization and speed that modern consumers expect while maintaining the empathy of a physical interaction. This intersection is where the customer experience is being rebuilt in real time.
