eSIM Adoption Is at Record Highs. Here's Why That Matters
In 2024, GSMA Intelligence estimated over 300 million eSIM-capable devices were in active use globally. By 2026, that number has climbed sharply as eSIM-only devices (US iPhones from the 14 series onwards, and various new Android flagships) make up an increasing share of new handset sales.
This isn't just a technical milestone. The growth has real consequences for how the mobile industry works and what it means for people who travel.
Why adoption has accelerated
Apple's decision to remove the physical SIM slot from US iPhone 14 models was the single biggest trigger. When the world's most-sold premium smartphone forces eSIM on its largest market, the ecosystem has to catch up quickly. Carriers that didn't support eSIM activation saw customer complaints. Apple retail stores started needing to train staff on eSIM setup rather than SIM swaps. The whole supply chain shifted.
The other driver is the normalization of international travel post-pandemic. Travellers who discovered eSIM convenience during resumed travel in 2022-2023 didn't go back to buying physical SIMs. Word of mouth spreads fast in the travel community.
What it means for travellers
More competition and lower prices. As more eSIM providers enter the market and carrier support grows, pricing has become more competitive. Plans that cost £15 for 5GB two years ago are now closer to £8-10 for the same allowance in most major markets.
Better carrier coverage. When more users are on eSIM, carriers prioritise their eSIM infrastructure. Activation times have dropped. Profile download reliability has improved. Network agreements between eSIM aggregators and local carriers have gotten better.
What it means for carriers
Less good news for carriers who built their business model around locking customers to physical SIMs. eSIM makes switching trivially easy - there's no physical barrier to changing providers. Carriers are responding by investing more in service quality and less in lock-in tactics.
Some carriers are still dragging their feet on eSIM support. A few markets - particularly some Middle Eastern countries - have been slow to enable eSIM activation due to regulatory or competitive reasons. That's changing, but not everywhere at the same pace.
The longer view
Physical SIM cards will likely still exist for five to ten years in some form. But they're clearly on their way out as the mainstream option. The industry has crossed the tipping point where eSIM is the default for new premium devices, and that trajectory only goes one way.
For travellers, the practical result is that the tools and coverage available via eSIM will keep improving. More countries, better network agreements, simpler activation. The current experience, already pretty good, will get better.
