MWC Barcelona 2026: Enterprise eSIM, Travel eSIM and IoT Connectivity Trends
10th March 2026
With more than 105,000 attendees from across the telecom ecosystem, this year’s event highlighted how organisations are scaling global connectivity strategies to support international operations, connected devices and mobile workforces.
Last week, the Telecom26 team joined telecom operators, technology providers, startups, enterprises and policymakers for a week of innovation and industry discussions at MWC Barcelona, the world’s largest connectivity event.
Celebrating 20 years in Barcelona, the event continues to serve as the most important annual meeting point for the global telecom ecosystem.
For Telecom26, the week was an opportunity to meet partners, customers and industry peers while discussing the growing demand for enterprise eSIM solutions, global IoT connectivity and secure mobile infrastructure supporting international operations.
During the event, Telecom26 also highlighted several recent developments, including our strategic partnership with BAO Systems and the launch of our eIM platform for scalable global IoT connectivity developed in partnership with Trasna.
Key Takeaways from MWC Barcelona 2026
- Enterprise eSIM adoption continues to accelerate as organisations expand internationally
- The travel eSIM market is expected to approach $5 billion globally in 2026
- Large-scale IoT deployments require advanced lifecycle management, increasing interest in eIM technology
- AI infrastructure and sovereign AI strategies are becoming central topics across telecom networks
- Security and digital trust remain key priorities for operators and enterprises
MWC26 in Numbers
MWC Barcelona continues to demonstrate the scale and importance of the global connectivity industry.
Key highlights from MWC26 include:
- 105,000+ attendees from around the world
- Participants from 207 countries and territories
- 2,900 exhibitors, sponsors and partners
- 1,700+ speakers and industry leaders
- 188 government delegations participating in the Ministerial Programme
- 17% C-suite attendees and 45% director level and above
- 1,000+ startups showcased through the 4YFN innovation platform
- $70 billion in investor funds represented at 4YFN
- 2,600 journalists and analysts covering the event globally
These figures highlight why MWC remains the most influential global event for the telecom and connectivity ecosystem.
Innovation Across the Mobile Ecosystem
MWC26 showcased innovation across the telecom sector from AI-powered infrastructure and robotics to next-generation devices and startup technologies.
New showcase areas such as Airport of the Future and New Frontiers demonstrated how connectivity is enabling intelligent infrastructure and automation across industries.
Startup innovation also played an important role. The 4YFN platform hosted more than 1,000 startups and hundreds of investors, highlighting the continued growth of digital innovation across sectors including healthcare, finance and smart infrastructure.
Nicola Berardocco, CEO of Telecom26, commented:
“MWC continues to be one of the most important moments in the telecom calendar. What stood out this year was the pace at which enterprises are scaling global connectivity strategies. Organisations increasingly require flexible, secure and scalable mobile infrastructure that allows them to operate across borders and networks without complexity.”
AI Moves to the Centre of the Telecom Industry
Artificial Intelligence was one of the dominant themes throughout the event.
Discussions ranged from sovereign AI infrastructure and national digital strategies to the growing role of physical AI powering robotics and connected devices.
However, industry analysts also highlighted that telecom operators must move beyond using AI purely for cost optimisation and begin demonstrating how it can generate new revenue opportunities and service innovation.
As AI-driven applications continue to expand globally, reliable and secure connectivity infrastructure will remain essential for supporting these technologies.
Travel eSIM Becomes a Strategic Market
Another clear trend at MWC26 was the rapid growth of the travel eSIM market.
Industry discussions highlighted how travel connectivity is evolving into a strategic ecosystem involving mobile operators, connectivity platforms, travel companies, device manufacturers and digital service providers.
Research presented during the event indicates that many international travellers still avoid traditional roaming due to cost concerns, relying instead on Wi-Fi or alternative connectivity solutions. These travellers, sometimes referred to as “silent roamers” represent one of the largest growth opportunities for digital connectivity services.
The global travel eSIM market is expected to approach $5 billion in annual spend by 2026.
For organisations with globally mobile teams, this trend is also driving demand for enterprise connectivity solutions.
Telecom26 supports international workforces through its Business Travel eSIM solution, providing secure enterprise-grade connectivity across more than 200 countries while simplifying roaming management and cost control.
eSIM IoT Connectivity for Fleets of All Sizes
While large-scale IoT deployments continue to expand across industries such as manufacturing, logistics, healthcare, energy, and maritime, a major shift discussed at MWC26 was the newfound accessibility of these technologies for operations of every scale.
Historically, managing eSIM profiles remotely was a complex, resource-heavy process often reserved for organisations deploying hundreds of thousands of devices. Now, the emerging eIM (eSIM IoT Manager) architecture is leveling the playing field, making advanced lifecycle management accessible and cost-effective for fleets of any size.
David McCanny, VP Commercial Operations at Telecom26, said:
“With the introduction of eIM, the benefits of eSIM are no longer restricted to massive global fleets; small to medium IoT deployments can now fully take advantage of this technology. Bringing the agility of eSIM to the broader M2M market is a massive step forward. It ensures that even the most inaccessible devices—in some of the most isolated places on Earth—benefit from enhanced security and seamless fallback capabilities, keeping mission-critical operations online without the need for physical SIM swaps.”
Telecom26 supports organisations deploying connected devices globally through its IoT / M2M Connectivity solutions, enabling secure global connectivity with multi-network coverage and centralised SIM lifecycle management.
What is Enterprise eSIM?
Enterprise eSIM refers to remote SIM provisioning technology that allows organisations to deploy and manage mobile connectivity across smartphones, routers and IoT devices without physically replacing SIM cards.
This technology simplifies connectivity management for multinational companies, allowing mobile profiles to be updated remotely across global device fleets.
Security, Fraud and Digital Trust
Security also featured prominently at MWC26. Industry experts discussed the growing threat of digital fraud, impersonation scams and cybercrime, highlighting the importance of collaboration across the telecom ecosystem.
Initiatives such as the GSMA’s United Against Scams aim to strengthen digital trust and protect users as connectivity becomes increasingly embedded across digital services and critical infrastructure.
Looking Ahead
MWC Barcelona continues to serve as a key platform for collaboration across the global telecom ecosystem.
For Telecom26, the conversations and insights from this year’s event reinforced our mission to support organisations with secure, scalable and flexible global connectivity solutions.
As enterprises expand internationally, travel connectivity evolves and IoT deployments scale across industries, Telecom26 remains focused on simplifying connectivity through enterprise eSIM solutions, Business Travel connectivity and resilient IoT infrastructure.
