- Awareness of eSIM technology among UK mobile users has jumped sharply, with over 70 % considering its use for international trips.
- The trend signals a shift away from traditional roaming towards more flexible, digital-first connectivity options.
What happened: Rising UK interest in eSIM travel connectivity
Awareness and intention to use embedded SIM (eSIM) services has climbed significantly in the UK, according to recent research from analyst firm CCS Insight. Over 70% of respondents said they would consider using an eSIM on their next overseas trip, a marked increase from just 27% who were aware of eSIMs in 2022.
About a third of those surveyed have already used a travel eSIM with a UK provider, with Apple iPhone users leading adoption thanks to broad device support. This includes devices like the latest iPhone Air, which has eSIM-only configurations. The shift is not purely anecdotal: global revenue from travel eSIM packages nearly doubled from 2024 to 2025, approaching $1.8 billion, reflecting strong consumer and provider momentum.
Users cite convenience and potential cost savings versus traditional roaming as key drivers, with travel eSIMs allowing data plans to be activated digitally before departure and eliminating the need to swap physical SIM cards abroad.

Why it’s important
The accelerating adoption of eSIM technology among UK travellers is more than a consumer trend – it underlines a structural shift in mobile connectivity. Traditional roaming plans, historically a reliable revenue stream for operators, are increasingly viewed as expensive and cumbersome, especially against the backdrop of user expectations for seamless, flexible services.
For mobile network operators (MNOs) and mobile virtual network operators (MVNOs), this shift presents both opportunity and pressure: those able to offer compelling travel eSIM packages or integrate eSIM services directly into broader digital offerings (such as travel or fintech ecosystems) may gain market share, while others risk ceding ground.
From a financial perspective, the migration towards eSIM for travel could erode traditional roaming margins unless operators adjust pricing structures or innovate with value-added services. The broader industry context suggests that by 2030 eSIM connections could represent a majority of smartphone links worldwide, reinforcing that this is not a niche innovation but a mainstream connectivity evolution.
