IDEMIA Secure Transactions (IST) and eSIM Go have formed a new partnership designed to strengthen global eSIM security and streamline how organisations deliver digital connectivity services. The agreement brings together IST’s proven secure-provisioning infrastructure with eSIM Go’s flexible, high-scale digital platform, enabling both emerging and established service providers to offer fully branded, secure eSIM services with minimal complexity.
Securing seamless eSIM experiences worldwide
With global adoption of eSIM technology accelerating across travel, telecommunications, fintech and smart-device ecosystems, demand is rising for activation systems that are easy to integrate and secure at scale. Under the partnership, eSIM Go will leverage IDEMIA Secure Transactions’ remote eSIM provisioning platform — trusted globally — to ensure secure activation and frictionless connectivity in more than 190 countries.
The companies say the collaboration sets a new benchmark for secure, end-to-end eSIM deployment, allowing organisations to introduce or expand digital connectivity offerings without compromising on integrity, identity assurance or user experience.
Combining security, scalability and digital trust
IDEMIA Secure Transactions will host the Consumer eSIM platform for eSIM Go in Europe, leveraging IST’s multi-region architecture, which is designed to deliver resilience, data sovereignty and full compliance with stringent EU security requirements. eSIM Go, meanwhile, will integrate IST’s secure infrastructure into its cloud-based, award-winning eSIM platform, which provides millions of eSIMs through B2B2C partner distribution and global Tier-1 mobile network access.
The partnership also enables eSIM Go to benefit from IST’s tailored onboarding solutions — engineered to align with diverse mobile operator security standards — while maintaining full control of eSIM profile management and service delivery. This simplifies integration for brands and ensures consistent, compliant connectivity for end users across international markets.
Mikkel Escartin, Head of Digital Solutions for Connectivity Services at IDEMIA Secure Transactions, said the partnership reflects a shared commitment to secure digital transformation. “This partnership illustrates how advanced security and exceptional user experience can go hand in hand. Together, we are helping companies around the globe accelerate their digital transformation while ensuring the highest levels of trust and protection for end users.”
Darren Shaw, Chief Product Officer at eSIM Go, said the collaboration supports the company’s quality-first strategy. “As the eSIM market has grown, a clear distinction has emerged between those prioritising quality versus the rest. At eSIM Go, quality and ease are everything. We understand the critical importance of security and provisioning when innovating and operating at scale — that’s why IDEMIA Secure Transactions is an important part of our global best-in-breed infrastructure strategy.”
Shaw said that with Tier-1 MNO access across 190+ countries and independently validated stability and performance benchmarks, the combined solution ensures optimal reliability and customer experience for partners worldwide.
The partnership positions IST and eSIM Go to meet surging demand for secure digital connectivity — and to support organisations building trusted, scalable eSIM-driven customer experiences in an increasingly mobile, data-sensitive global environment.
