Used Quantroam in Sri Lanka for two weeks. Savings were insane, 70% less than roaming. The interactive globe is cool, and coverage was solid in Colombo and Galle. Definitely using this again.

Great experience! Easiest installation I've had with eSIMs. Installed it on a layover and had internet before I got off the plane. Definitely recommend to friends!
Gabi
My telco wanted $15/day for Europe. Found Quantroam and paid less than half for the week. The interactive globe is great, and connection was reliable. Wish I'd known about eSIMs sooner!
