Our engineering team includes alumni from major carriers and cloud hyperscalers, blending telecom rigor with Silicon-Valley agility. Today, our GSMA-certified platform provisions millions of eSIM profiles each year for travellers, remote employees, and smart devices in over 190 countries.

Each physical SIM discarded adds plastic and metal to landfills. By switching to eSIM, our customers have already kept 7.2 million plastic cards out of circulation—saving an estimated 480 metric tons of CO₂ every year.
Our Denver data center runs on 100 % renewable energy credits, and we offset remaining emissions through verified reforestation projects in Colorado’s High Country.
