The story

ZIM Connections are a leading UK eSIM marketplace where customers browse and purchase affordable global travel data plans. Founded in London in 2020 by serial travellers Giulia Acchioni and Irina Gheorghiu, after they kept hitting the same problem: getting an internet connection abroad.

The objectives

  • Bring eSIM technology to consumers
  • Make it easy for travellers to connect with people back home
  • Help consumers avoid unfair roaming bills
  • Develop an online marketplace that champions choice and flexibility

The challenges

Mobile connectivity is a complex industry, with different laws and regulations across the world. Consumer awareness of eSIM was low, most telecoms providers hadn’t yet ventured into it, and the founders came from finance and economics backgrounds, not telecoms.

Why eSIM Go

The two companies met at MWC Barcelona in 2021 and found a shared vision. What made eSIM Go the right platform underneath:

  • Extensive telco experience and a real understanding of eSIM
  • Products based exclusively on the highest quality tier one mobile networks
  • A sound understanding of regulatory requirements
  • An eSIM platform built for wholesale distribution
  • A fully documented API
  • A clear pricing structure
“eSIM Go and ZIM Connections are eager partners who have tirelessly expanded the world of connectivity and eSIM for the past three years. Collaborating with eSIM Go has been fundamental to building and delivering our product to connect 80K+ travelers worldwide. As we are leaning further towards a new era of mobile connectivity, strengthening our partnership is vital for both companies and the success of the eSIM revolution”Giulia Acchioni-Mena, COO and co-founder, ZIM Connections

The results

  • The leading eSIM marketplace in the UK
  • A 30% month-on-month returning customer rate
  • A 4.7 review rating
  • Data roaming solved for 80,000+ customers
  • Multiple business awards
  • A B2B offering launched for corporate customers
  • Extended product choice, with unlimited bundles and customised data plans
“The introduction of unlimited plans has been a huge success and has really helped our customers. One of the things we’re most commonly asked is how much data people need, and now they don’t have to think about it. This is all a big part of our ethos of giving people the choice and information they need to make informed decisions.”Giulia Acchioni-Mena, COO and co-founder, ZIM Connections

Looking ahead

ZIM Connections are expanding their B2B offering for companies that keep travelling workforces connected. A successful pilot in Switzerland is now being duplicated across markets, supported by a dedicated account manager at eSIM Go.

“We’re living in the second golden age of the telco sector. It’s pleasing to witness the innovation eSIM has brought to this traditional sector, and exciting to share the journey with eSIM Go, a trailblazer company and trusted partner.”Nick Fidale, Chief Product Officer, ZIM Connections
