eSIM Go secures funding led by Eurasian telecoms group TNS Global, to scale MVNO platform

The London-headquartered eSIM specialist eSIM Go has announced a strategic investment round led by TNS Global, a Eurasian digital infrastructure and wholesale telecommunications provider headquartered in Dubai. The deal marks a significant step change for a company that has grown organically since its 2020 launch into what it describes as a leadership position in the B2B Travel eSIM market. A segment forecast to expand at a compound annual growth rate of 37% through to at least 2030.

“We are excited to support eSIM Go in its next phase of growth,” said Obaid Rahman, Group CEO at TNS Global. “The company represents a strong strategic fit with our vision to expand into scalable, profitable and high-growth digital connectivity segments, complementing our core digital infrastructure footprint.”

While eSIM Go built its reputation serving travel brands, MNOs, fintechs and loyalty platforms (covering over 1,200 networks across 190-plus countries), the investment also shines a light on a second, arguably more transformative, chapter: its UK MVNO enablement business.

Following the launch of its UK MVNO capability in partnership with Vodafone Three in the second half of 2025, eSIM Go has since secured commercial partnerships with a wave of emerging brands – among them Loopdl, SecondSIM, Faith Mobile and Symu. The proposition is deliberately low-friction: prospective MVNOs can access the infrastructure via API, co-brand a managed service, or enter through an affiliate route, with the company positioning itself as the means by which new mobile brands can reach market with virtually no barriers to entry.

That last point carries particular weight in the context of underserved communities. eSIM Go has identified brands serving migrant diaspora communities as a core MVNO growth segment. A cohort that has historically been poorly served by incumbent operators and represents a significant commercial opportunity for digital-first challengers.

Zacc Couldrick, co-founder and CEO at eSIM Go commented: “Our focus is profitable and cash-generative growth, scaling early success in the UK MVNO market, and consolidating our market leadership in the eSIM enabler space. This investment marks a new era for eSIM Go, as we mature the company upon the solid foundations of a resilient team and best-in-class technology at the experience layer.”

TNS Global’s infrastructure spans key international corridors connecting Europe, the Middle East, Asia and beyond, a footprint that maps neatly onto the regions where eSIM adoption curves are steepening. For eSIM Go, which has already identified Africa, Latin America and parts of Asia as emerging Travel eSIM markets, the partnership opens doors that capital alone could not.

Couldrick was candid about what the investor brings: “We seek to maintain and strengthen our position as the gold standard in Travel eSIM for partner and end-user experience. The core eSIM Go management team remains in place, the timing is perfect for welcoming such vastly experienced investors from the MVNO and wholesale space to open more doors and bring strategic, operational, regional and commercial advantages.”

With the Travel eSIM market maturing and the UK MVNO market fragmenting rapidly, the company’s bet is that the combination of Eurasian reach, wholesale depth and a proven enablement platform will allow it to grow on two fronts simultaneously.
