The travel connectivity space is changing fast, and Roamify is positioning itself at the center of it. The company says it now operates more than 20,000 active eSIM plans across 195+ countries, and claims to have built the world’s largest eSIM API library — an achievement that reflects both growing demand and a shift toward API-driven connectivity.

The milestone is significant because Roamify isn’t just another eSIM retailer. It’s part of a broader movement transforming how global connectivity is built, distributed, and monetized.

From eSIM Provider to Platform

Roamify’s model extends beyond selling data plans directly to travelers. The company has quietly been building a comprehensive API library that allows partners—including airlines, mobile operators, digital banks, and travel technology startups—to integrate eSIM activation, data management, and top-up functions directly into their systems.²

According to CEO Dveer Zvi, the goal is to make global connectivity “faster, more affordable, and seamless to integrate.”

The technical foundation is solid. Roamify’s public API documentation outlines endpoints for plan discovery, activation, billing, and order management — all standard components of a modern connectivity API. This mirrors what the broader telecom ecosystem is doing as it moves toward open, programmable interfaces that support automation and embedded services.

The Rise of White-Label eSIM Solutions

Roamify’s standout feature is its white-label platform, designed to let companies launch branded eSIM offerings with minimal infrastructure investment. Partners integrate Roamify’s API stack for provisioning, fulfillment, and customer support, while maintaining control over branding, marketing, and user experience.

It’s part of a larger telecom trend where enabling platforms—such as 1GLOBAL, Telna, or eSIM Go—provide the backend, letting non-telecom brands offer connectivity as a service. Roamify’s focus on simplicity and affordability makes it particularly appealing to startups and digital-first businesses that want to move quickly.

Still, the “no infrastructure required” tagline should be read as shorthand. Partners do need commercial agreements, customer interfaces, and compliance processes. But compared with building from scratch, Roamify’s platform offers an unusually low barrier to entry.

How Travelers Benefit

Although Roamify’s current growth is largely B2B-driven, its consumer plans remain a major draw for frequent travelers. Independent eSIM reviewers like Travel eSIM Expert have ranked Roamify among the most affordable global options, noting particularly strong pricing across Europe and Asia.

Pricing varies by region, but Roamify’s focus on cost-per-gigabyte efficiency has consistently placed it among the cheapest choices in international eSIM comparisons. It also offers 24/7 multilingual support and maintains generally positive user reviews, averaging around 4.5 stars across major app stores—though ratings, as always, fluctuate by time and region.

Unlimited Data, Explained

The word “unlimited” has become a minefield in the eSIM world. Many providers throttle speeds to as low as 128 kbps or 1 Mbps after just a few gigabytes of use—effectively ending any real-world “unlimited” experience.

Roamify takes a slightly different approach. According to user reports and third-party reviews, its post-FUP speeds often remain around 5 Mbps, which is still fast enough for HD video calls and streaming. Some regional plans reportedly maintain full speed indefinitely, but travelers should always check the Fair Usage Policy before purchase.

This more transparent and usable model has helped Roamify stand out in a crowded market where “unlimited” often comes with hidden limits.

APIs and the Future of Travel Connectivity

Behind the consumer-friendly pricing and app interface, Roamify’s API expansion may be the company’s most strategically important move. Its infrastructure allows other businesses to embed eSIM functionality directly into their platforms, effectively turning connectivity into an invisible background service.

Picture this: you book a flight, and the airline automatically provides you with a local eSIM for your destination. Or your digital bank offers discounted data roaming as part of your premium account. These are exactly the types of use cases Roamify’s platform can enable.

Industry data support the direction. GSMA Intelligence projects that the number of eSIM smartphone connections will reach up to 6.7 billion by 2030, while Counterpoint Research estimates 2.2 billion IoT eSIM connections in the same period.⁶ As more devices and apps integrate eSIM functionality, API-based distribution will only accelerate.

Competitive Landscape

The eSIM industry remains crowded, with major consumer brands like Airalo, Ubigi, YESIM, or Nomad leading public awareness. But Roamify’s differentiation lies beneath the surface: it’s building the infrastructure others can use to launch their own offerings.

That’s the same playbook that turned companies like Stripe (for payments) and Twilio (for communications) into giants—powering the market rather than competing for retail dominance.

Platforms that enable rather than compete often shape the direction of entire industries. If Roamify continues to expand its API library and maintain competitive pricing, it could become one of the unseen backbones of travel connectivity.

The Takeaway about Roamify eSIM API

Roamify’s claim to operate the world’s largest eSIM API library should be viewed as a self-reported achievement, but its technological foundation and growth momentum are undeniable. The company is evolving from a travel eSIM provider into a connectivity infrastructure platform — one that makes global mobile access easier for both consumers and businesses.

For travelers, that means more affordable, flexible data plans with fewer restrictions.
For companies, it’s a ready-made toolkit to embed global connectivity into their services.
And for the industry as a whole, it’s another sign that the next phase of the eSIM revolution will be built through APIs—not apps.
