eSIM Go, a tech startup, has secured a growth funding round led by TNS Global to accelerate geographic expansion and push deeper into the UK MVNO market and travel eSIM space. The strategic investment will be used to develop the company’s connectivity platform, support profitable growth and extend its reach across Eurasia and other regions.
Why it matters
The deal highlights the commercialisation of eSIM technology beyond initial consumer use. Juniper Research projects the travel eSIM market to grow rapidly, and suppliers that combine global connectivity with easy-to-integrate product layers stand to benefit as travel, fintech and digital service firms embed mobile services. For the UK specifically, the removal of technical and commercial barriers to launching MVNO services could lead to a more fragmented market, creating opportunities for niche consumer brands and those serving migrant communities.
Inside the product
eSIM Go provides an end-to-end eSIM product ecosystem: APIs for embedding connectivity into partner products, fully managed co-branded services and affiliate routes. Its catalogue covers data bundles on more than 1,200 networks across 190+ countries, aimed at partners in travel, mobile virtual network operator (MVNO) and fintech sectors.
The company launched a UK MVNO in partnership with Vodafone Three in the second half of 2025. Dozens of commercial partners have gone live on that platform, including Loopdl, SecondSIM, Faith Mobile and Symu — all early entrants using the white-label or API-based routes to offer consumer mobile services with lower setup friction.
Who are the investors?
The round is led by TNS Global, a Dubai-headquartered Eurasian digital infrastructure and wholesale telecommunications provider that supplies connectivity, voice, messaging and IP transit across Europe, the Middle East and Asia.
In the announcement, Obaid Rahman, Group CEO at TNS Global, said:
We are excited to support eSIM Go in its next phase of growth. 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.
TNS Global’s stated rationale is strategic rather than purely financial: the firm aims to leverage its wholesale and regional network footprint to help eSIM Go expand into Eurasia and adjacent markets, while supporting technology evolution and commercial scaling. No other investors were named in the release.

Founder perspective
In the announcement, Zacc Couldrick, co-founder and CEO at eSIM Go, said:
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.
Couldrick also noted that the core management team remains in place and that the new investor relationships are intended to bring operational and regional expertise to open further commercial doors.
The bigger picture
This transaction is part of a broader shift in telecom: connectivity is being unbundled and offered as a platform capability to non‑telco brands. For startups and established firms alike, the ability to launch mobile services via APIs and white-label MVNO arrangements reduces time to market and upfront cost. Markets in Africa, LATAM and parts of Asia remain cited as growth opportunities where localisation and distribution partnerships will be decisive.
For the UK and Europe, the deal underlines growing activity around MVNOs and eSIM enablers. As regulatory frameworks evolve and wholesale partnerships proliferate, expect further investor interest in companies that can stitch global network reach to consumer-facing product layers.
