Who We Are
Rainbow eSIM was born from a simple idea: make global connectivity seamless for all travelers. Whether you’re hopping between cities for business, exploring off-the-beaten-path destinations, or staying with family abroad, you deserve fast, reliable connectivity — without hidden fees, surprise data caps, or confusing plans.
We deliver both e-SIM and physical SIM plans crafted to keep you connected wherever your journey takes you. Backed by deep telecom expertise and a philosophy of transparency, we believe staying connected should be one of the easiest parts of travel.
Our Story
Founding
Rainbow eSIM was founded by a group of frequent travelers and telecom engineers who were frustrated by dropped signals, exorbitant roaming fees, and opaque plan contracts. The vision was clear: build a service that travelers could trust — one that offers full visibility, honest pricing, and excellent global coverage.
Growth
Since launching, we’ve partnered with global carriers in many countries to ensure strong network coverage and speed. We’ve expanded our plan options, simplified onboarding, and built in customer support systems to handle every time zone, every kind of issue.
Why We Exist
Because nobody should have to scramble for WiFi, endure surprise roaming bills, or settle for poor service just because they cross a border. Travel is already complex enough — your connectivity shouldn’t be.
Mission
Our mission is to provide travelers with seamless, affordable global connectivity, enabling them to explore, work, and stay connected without disruption.
