The Silent SIM: Why Your Next Phone Probably Won’t Have a Physical SIM Card Anymore
For over a decade, a quiet revolution has been brewing in the world of mobile connectivity. It’s called eSIM – an embedded SIM card that’s built directly into your device. While the technology itself isn’t new, its widespread adoption has been a slow burn. Last year, only about 3% of global mobile users were tapping into the eSIM network, and this year, that number is projected to barely nudge past 5%. Yet, despite these seemingly modest figures, a palpable buzz is emanating from analysts, burgeoning eSIM startups, and eager investors. They’re all betting big on eSIM’s exponential growth, and a significant portion of this optimism is being fueled by one thing: travel.
Device Evolution: From Niche Feature to Mainstream Staple
One of the most powerful drivers behind eSIM’s ascent is the increasing commitment from smartphone manufacturers. We’re witnessing a clear trend: devices are being launched with eSIM capabilities as a standard, not just an optional extra. It began subtly, with early adopters like the Google Pixel 2 and the Apple iPhone XR paving the way in 2017 and 2018. However, the real turning point arrived in 2022 when Apple made a bold move, ditching the physical SIM slot entirely for its U.S. market with the iPhone 14 series. Google soon followed suit, integrating eSIM-only capabilities into its Pixel 10 devices this year.
Apple has continued to push the envelope, introducing the eSIM-only iPhone Air and offering an eSIM-only variant of the iPhone 17 series in over 11 countries. This strategic shift isn’t just about innovation; these eSIM-only models often boast a slightly improved battery life compared to their physical SIM counterparts. The numbers reflect this growing momentum. Analytics firm Counterpoint reports that by 2024, a quarter (23%) of all smartphones launched will feature eSIM technology. The United States stands out as a leading market, with a remarkable 41% of devices released in 2024 equipped with eSIM functionality.
Historically, eSIM was a premium feature reserved for high-end devices. However, this exclusivity is rapidly dissolving. The GSMA, the global mobile communications industry association, notes that in the first half of 2025 alone, over 60 eSIM-enabled smartphones were launched by various brands. This expansion across different price points is crucial for broader consumer uptake.
China’s Crucial Role in the eSIM Landscape
The massive Chinese market is poised to become a significant catalyst for eSIM adoption. Following a period of adjustments, China’s major telecom providers began offering eSIM support in October, coinciding with the launch of Apple’s eSIM-only models. Pablo Iacopino, a senior analyst at the GSMA, anticipates that prominent local manufacturers like Huawei, Xiaomi, Oppo, and Vivo will increasingly introduce devices with native or robust eSIM support. This is particularly impactful given these brands’ strong presence in cost-sensitive markets across Asia and Africa. They have the potential to integrate eSIM capabilities across a wider spectrum of devices, catering to domestic demand.
"Chinese brands, when they see that the Chinese MNOs have launched eSIM services for the domestic Chinese market, they will probably start introducing eSIM across a wider range of smartphones, including, medium and low-end market," Iacopino explains. "But I don’t think they will go eSIM only immediately. They will start with supporting both physical and eSIM, before shifting to eSIM-only models."
Even with eSIM-enabled devices becoming more prevalent, the actual utilization of the technology has lagged. However, this is rapidly changing. Steffen Sorrell, head of research at telecom analyst firm Kaleido Intelligence, observed that in 2024, approximately 30% of devices with eSIM capabilities were actually activated with an eSIM plan. Kaleido Intelligence projects this activation rate to soar to an impressive 75% by 2030.
Travel: The Unexpected Champion of eSIM Convenience
When you think about the primary reason people are embracing eSIM, travel consistently emerges as the top driver. For globetrotters, eSIM offers an unparalleled level of convenience. Need a local SIM card in a foreign country? Forget hunting for stores and dealing with language barriers. With eSIM, you can download a plan before you even leave home or upon arrival, often in a matter of minutes.
A GSMA survey revealed that a staggering 51% of eSIM users cite travel as their primary reason for adopting the technology. Beyond convenience, eSIMs offer enhanced security. The technology is often integrated with secure hardware elements, making it significantly harder to tamper with than a physical SIM card. This blend of ease of use and security has been a boon for eSIM providers and startups like Airalo, Holafly, eSIM.me, Nomad, and even security-focused companies like NordVPN, which launched its Saily eSIM app.
These companies are experiencing significant growth, largely propelled by the influx of travelers. "People might experience eSIM for the first time while traveling. These users who like the eSIM experience would go back home and request their network providers to make a switch from a physical SIM," GSMA’s Iacopino shared in a recent interview.
Airalo, one of the leading eSIM providers, has been instrumental in introducing many users to the technology. Their CEO, Bahadir Ozdemir, reported that a survey on their app found that 85% of respondents were first-time eSIM users. "Roughly 15% of travel connectivity is being powered by eSIMs, and the number is growing. Once users discover how they can get connectivity with eSIM, they don’t really want to go back to the old way [physical SIMs] of doing it," Ozdemir commented.
He further elaborated on the challenge of discoverability: while many telecom operators offer eSIMs, finding them can be difficult for consumers. Apps like Airalo simplify this process, making it seamless to access global connectivity. Even major network providers are recognizing the potential, with companies like Vodafone partnering with events like UEFA to offer specialized eSIMs for travelers attending major sporting events.
Investment Flows: A Bullish Outlook for eSIM Startups
The travel-centric eSIM market is attracting significant investor attention. Startups like Truely, which has served over 70,000 travelers in the past two years and reported a doubling of order growth this year, have secured substantial funding. Truely raised a $2 million extension round in June and is actively exploring partnerships with fintech services, travel apps, and even governmental bodies.
NordVPN’s Saily eSIM app has also seen remarkable traction, reaching a seven-digit user base shortly after its launch in March 2024, even introducing a premium $60 per month global coverage plan. Holafly, a veteran in the space since 2018, has sold over 15 million eSIMs and surpassed $500 million in total revenue, with $200 million generated in 2024 alone.
The most significant financial endorsement came with Airalo’s $220 million unicorn-making funding round in July, led by CVC. This marked the largest eSIM investment in recent memory. French startup Kolet also secured $10 million in Series A funding, backed by Daphni and notable figures from the travel tech industry.
Scott Shiao, a principal at Goodwater Capital, believes the current investment focus is predominantly on consumer-facing, travel-related eSIM startups. However, he acknowledges the future potential for domestic market applications. Martell Hardenberg, a partner at Antler, echoes this sentiment, highlighting that while the travel use case is strong, the market is still in its early stages, with ample room for growth. "I think there is opportunity in offering bundled services to global travelers or digital nomads about what companies can offer beyond travel SIM cards and make it a lucrative package for these user profiles," Hardenberg suggests.
Looking ahead, investors will be scrutinizing not just market reach but also long-term viability. Kaleido Intelligence’s Sorrell anticipates a potential consolidation phase in the future as the market matures. "The market is obviously on its way up, but I think sooner or later we’re going to reach a saturation point in terms of the providers on the market there. So investors will look into the long-term viability of the business along with things like customer loyalty, quality of coverage, and even association with marketing capabilities, how you’re able to promote that eSIM, whether it’s through airlines, banks, or cab companies," he advises.
Navigating the Hurdles: Education, Trust, and User Experience
Despite the promising trajectory, eSIM adoption faces a few significant challenges. Foremost among these are education, trust, and the perceived ease of use. Many consumers simply don’t understand what an eSIM is or how it works. "Spotify can tell people to download Spotify because people know about music, and Netflix can tell people to download Netflix because people know about TV shows," Airalo’s Ozdemir explains. "But we couldn’t do that with Airalo, as a lot of people don’t know about eSIMs." To combat this, companies are investing in influencer marketing and educational content to demystify mobile connectivity on the go.
Eric Dadoun, CEO of Truely, believes that as eSIM-only devices become more common, consumers will be compelled to learn about the technology. For now, in markets where purchasing an eSIM-only device is still optional, user education remains a key focus for customer acquisition.
One of the more cumbersome aspects of the current eSIM experience is the installation process. Typically, when you purchase an eSIM plan, you receive a QR code via email. To activate it, you need to scan this code with your device. This necessitates having a second device readily available – a significant hurdle if you’re in a foreign country and relying solely on your new phone for connectivity.
GSMA’s Iacopino acknowledges this friction point, emphasizing that as eSIM adoption grows, both providers and hardware manufacturers must collaborate to streamline this activation process. Furthermore, some network providers are slower to transition to eSIM due to legacy infrastructure and outdated systems. For these organizations, a complete digitization of the SIM switching process, eliminating the need for physical store visits, is essential.
The Future is Seamless and Invisible
The journey of eSIM from a niche technology to a mainstream standard is well underway. Fueled by device innovation, strategic market entries like China’s, and the undeniable convenience it offers to travelers, the eSIM revolution is gaining unstoppable momentum. While challenges related to user education and onboarding persist, the inherent advantages of a more secure, convenient, and potentially battery-efficient connectivity solution are too compelling to ignore. As more devices become eSIM-only and the activation process becomes more intuitive, the physical SIM card we’ve relied on for decades may soon become a relic of the past, replaced by an invisible, integrated, and ultimately, superior way to stay connected.
