The Rise of Travel eSIMs: SEGRON’s Role in Ensuring Seamless Connectivity

The digital landscape is continuously evolving, and eSIMs are at the forefront of this transformation. These embedded SIMs (eSIMs) allow remote provisioning of subscribers without needing a physical card and are already widely used in IoT and M2M scenarios.

With the anticipated advent of new devices like the iPhone 16 as an eSIM-only device, the popularity and demand for eSIM technology are growing in the consumer segment. The first real use case appears to be the roaming market, where travel eSIM providers are emerging and revolutionizing how we stay connected while traveling. This shift presents both opportunities and challenges for connectivity providers and travelers alike.

eSIMs: The Future of Travel Connectivity

Travel eSIMs are gaining traction among international travelers who seek cost-effective connectivity without the hassles to buy local SIM in beforehand or upon arrival.

The high cost of traditional roaming outside Roam-Like-At-Home (RLAH) areas is the primary driving factor for travel eSIM adoption.  By 2028, it is estimated that 22% of international travelers will use travel eSIMs, reflecting a significant shift in consumer behavior towards digital-first connectivity solutions. The global eSIM market, valued at $4.8 billion in 2023, is projected to grow at a compound annual growth rate (CAGR) of 25.4% to reach $14.8 billion by 2028. (Source)
