When it comes to mobile technology, things are evolving at lightning speed. Every year, new devices hit the market, networks expand, and features that once seemed futuristic become standard. The Global Certification Forum’s (GCF) Device Technology Trends Report 2025 provides an in-depth look at these changes, highlighting what’s hot, what’s growing, and what’s fading away.

While the report covers a broad range of developments, there’s one key takeaway for travelers and tech enthusiasts: eSIM is taking off in a big way.

The Big Picture: What’s Happening in Mobile Tech?

In 2024, GCF certified 574 devices from 90 manufacturers. That’s nearly a 7% increase from 2023, and it shows that the mobile market is far from slowing down. While traditional LTE remains the dominant wireless standard, 5G is gaining ground rapidly. Almost half (48%) of certified devices in 2024 included 5G support—an impressive leap from just 38% in 2023.

Smartphones saw a notable increase in certifications, reaching 207 models, up from 184 in 2023. Interestingly, wireless modules (the little chips that enable connectivity in various devices) outpaced smartphones in certifications, showing the growing demand for connected devices beyond just phones.

The eSIM Boom: No More Physical SIMs?

One of the most exciting revelations in the report is the explosive growth of eSIM adoption. Remote SIM Provisioning (RSP) for eSIM has been around for six years, but 2024 marked a major milestone. More than half of all certified smartphones (51.7%) now support eSIM, a huge jump from just 34.8% in 2023 and a mere 15% in 2022.

In total, 142 devices were certified with RSP for consumer eSIM—up from 97 in 2023. This includes not only smartphones but also laptops, tablets, and wearables. While the number of standalone eSIM-certified devices (like connected laptops) dropped slightly, smartphones picked up the slack, making eSIM more mainstream than ever.

For frequent travelers, this is game-changing. No more fiddling with tiny SIM cards or hunting for a local SIM at the airport. With eSIM, you can switch carriers or activate a new plan with just a few taps on your phone. It’s flexible, efficient, and—most importantly—convenient.

5G: Growing but Not Replacing LTE Just Yet

5G adoption continues to rise, but the transition isn’t happening overnight. While 5G was included in 273 certified devices (a 48% penetration rate), LTE is still present in 88% of all certified devices. Many IoT applications and industrial devices don’t need 5G speeds, and LTE remains a stable, cost-effective option.

Interestingly, the number of devices supporting 5G standalone (SA) mode has reached 96.4%, meaning manufacturers are preparing for a future where 5G doesn’t rely on LTE at all. This is crucial for long-term network evolution, but for now, LTE isn’t going anywhere.

The Decline of 3G and the Longevity of 2G

While 5G is growing, older technologies are slowly fading. 3G is practically dead—there were no standalone 3G device certifications in 2024. But surprisingly, 2G (GSM) is still hanging on, mostly as a backup for voice and emergency services. In fact, four devices certified in 2024 were GSM-only, proving that legacy networks still have a niche role to play.

Satellite Connectivity: Not Quite Mainstream (Yet)

One of the most intriguing developments in the report is the growing role of non-terrestrial networks (NTN). In 2024, GCF certified its first device supporting NTN NB-IoT (which connects to geostationary satellites). While only one device made the list, it’s a glimpse into a future where smartphones and IoT devices can stay connected anywhere on the planet—no cell towers needed.

This is especially relevant for travelers venturing into remote areas. While satellite connectivity in phones is still in its infancy, the fact that it’s now part of GCF’s certification process signals that we’re moving toward a more connected world.

What Does This Mean for Travelers and Consumers?

For those who rely on connectivity while on the move, the trends in this report point to a more flexible, borderless future. Here’s what to keep in mind:

• eSIM is becoming the norm. If you’re buying a new smartphone, chances are it will have eSIM support. This means easier travel, better international roaming options, and the ability to switch carriers effortlessly.
• 5G is expanding, but LTE is still king. While 5G devices are on the rise, LTE remains the most widely supported network. If you’re traveling to regions where 5G isn’t fully deployed, LTE will still keep you connected.
• Traditional SIM cards will slowly fade. While they won’t disappear overnight, physical SIM cards are on the decline as eSIM adoption grows.
• Satellite connectivity is on the horizon. If you’re an adventurer or frequently visit remote locations, keep an eye on the development of NTN-based devices. The ability to stay connected anywhere, even in the middle of the ocean, is becoming a reality.

Final Thoughts about eSIM Trends 2025

The GCF Device Technology Trends Report 2025 paints an exciting picture of where mobile tech is headed. eSIM is growing fast, 5G is expanding, and new frontiers like satellite connectivity are emerging. For travelers, this means more freedom, fewer hassles, and better connectivity options no matter where you go.

If you’re still using a phone without eSIM, now might be the time to upgrade. And if you’re planning international travel, consider an eSIM provider to save on roaming costs. The future of mobile connectivity is here, and it’s looking more seamless than ever.
