eSIM Adoption Surges, Challenging Traditional Mobile Roaming Revenue

The adoption of eSIM technology is experiencing a significant surge, with global usage projected to increase by one-third this year. Analysts estimate approximately 134 million eSIMs will be used worldwide in 2026, up from 101.8 million in 2025. This trend, driven by travelers seeking to avoid high international roaming charges, is beginning to impact the revenue streams of major mobile phone companies.

According to reports, the revenue generated from roaming fees for major mobile providers typically falls between 3 and 5 percent. The increasing use of eSIMs poses a potential risk to this revenue, as consumers opt for more cost-effective and convenient alternatives. eSIM company Holafly noted a substantial increase in adoption among European travelers, with usage more than doubling to 44.8 percent when traveling outside the EU, underscoring the consumer demand for alternatives to expensive roaming.

Popular brands like Airalo and Saily, NordVPN's travel eSIM app, offer flexible data packages in numerous destinations, allowing users to maintain phone service without incurring hefty charges. This shift is being characterized by industry experts not as a direct threat, but as a healthy disruption to the traditional mobile data model.

Vykintas Maknickas, CEO of eSIM company Saily, stated that eSIMs are reshaping the roaming model, which was previously built on limited alternatives for travelers. He highlighted that eSIM providers are increasingly bundling services with data plans, offering perks such as airport lounge access, fast-track security, and digital security tools—features not typically associated with standard roaming.

Alfonso Mata, head of strategy at Holafly, views the eSIM growth as a reflection of evolving consumer expectations for staying connected abroad. He noted that while the demand for mobile data continues to rise, consumers are increasingly shopping around for data services, similar to how they purchase flights and hotels.

The advantages of eSIMs for consumers include enhanced reliability, predictable costs, and ease of use. Travelers can purchase and install eSIMs before their departure, ensuring immediate connectivity upon arrival. For multi-country trips, a single eSIM can provide data across various destinations without the need to physically swap SIM cards. Maknickas also pointed to cybersecurity benefits, with some eSIM applications offering built-in features to block malware and malicious websites.

Experts advise travelers to compare prices, data allowances, validity periods, and covered destinations when selecting an eSIM plan. For those who rely heavily on their devices, unlimited data plans are recommended for peace of mind. Purchasing eSIMs in advance, rather than at the airport, is also suggested to secure better deals and ensure seamless activation.
