eSIMzio is a travel eSIM app for 200+ destinations, built on one principle: nothing fake. Real prices up front (from £1.50), live data-usage tracking from the carrier, fair-usage limits shown BEFORE you buy (most "unlimited" plans throttle — we tell you exactly when), 2% cashback on every trip, and your number stays for calls and texts. iOS + Android.
Hi PH 👋 I built eSIMzio after one too many £40+ roaming weeks. The travel eSIM market is booming but murky — "unlimited" plans with hidden speed caps, prices that change at checkout, usage you can't see. So we ship the boring truth: the fair-usage policy on the plan card, live usage from the carrier (not an estimate), and if data isn't available yet we show a pending state instead of a fake number. Would love feedback — especially from anyone who's been burned by a roaming bill. Happy to answer anything about eSIM tech, provisioning, or building a React Native + Supabase + Stripe app to both app stores.
Report
Picked it up before a trip to Lisbon and the live carrier data tracking actually matched what my phone showed, which I did not expect from an eSIM app. Loved seeing the throttling threshold called out before checkout instead of buried in fine print.
Report
Love the transparency on throttling and real pricing — already rare in this space. One thing I'd love to see is a small offline-friendly "data needed for X trip" estimator (like "10 days in Tokyo = roughly 4GB") to stop me from overbuying every time. Would pair nicely with the carrier usage tracking.
