Roamless Secures $12M To Expand Global eSIM Connectivity Platform

This new capital brings Roamless' total funding to $18 million, following a $6 million seed round in 2024.

Founded in Türkiye and headquartered in the US, Roamless was established in 2023 by Emre Demirel, Ali Gazioglu, Asim Alp, Selim Aykut, Cagdas Yalti and Cengiz Oztelcan. The company offers a borderless mobile connectivity platform based around a single eSIM designed to work seamlessly across multiple countries.

Roamless provides a “Single Global eSIM” with pay-as-you-go and trip-based plans across 200+ countries, enabling travellers to stay connected without switching SIM cards. The company operates its own telecom infrastructure and plans to add features such as local numbers, voice, SMS and partner APIs. Roamless currently serves over one million travellers and collaborates with partners in the travel, aviation, and financial services sectors.

Roamless' telecom stack is a cloud-based, carrier-grade infrastructure layer that manages connectivity across hundreds of networks through a single service, enabling cross-border coverage. This infrastructure is designed to support services beyond just data offerings, while also giving Roamless greater control over the customer experience compared to a resale model.

The eSIM market has been growing rapidly, fueled by increasing adoption by smartphone manufacturers. While fewer than 20% of global smartphone connections used eSIM in 2024 the GSMA projects that penetration could reach 88% by 2030. Roamless expects this trend to continue as more devices transition away from physical SIM trays.

Emre Demirel, co-founder and CEO of Roamless, said the company expects the market to grow significantly and believes long-term winners will combine a strong product with reliable infrastructure and carrier-grade technology.

We are rolling our local market, b2b and AI-enabled features in our next phase - all to ensure we continue to lead on innovation, and give global mobile users what they need to maximise their experience.

In its next phase, the company will expand network coverage, scale global go-to-market and customer support, and strengthen supplier and corporate partnerships. It plans to launch Roamless Numbers for local calling and SMS in 20+ countries develop APIs and B2B solutions for travel and finance partners, introduce AI-driven network and cost optimizations, and grow teams in major travel hubs.
