Kolet
Kolet is a next-generation travel eSIM platform that provides seamless mobile internet access across over 190 countries without swapping physical SIM cards or reinstalling eSIM profiles when you change destinations; you install a single universal eSIM once and then top up data plans through the Kolet app, keeping your local number active and avoiding roaming charges while tracking usage and recharging as needed. It works on most eSIM-compatible smartphones, tablets, wearables, and some vehicles, offering prepaid data plans with no subscription or hidden fees; you can buy and activate plans digitally in minutes, manage multiple eSIM profiles, and use dual-SIM configurations to maintain your regular number alongside Kolet’s data. Kolet’s app allows travelers to browse destinations, choose data plans, install and activate eSIMs, monitor real-time usage, top up on the go, and share data with friends or family, while unused data can be reused on future trips.
