GigSky

GigSky predates the eSIM era itself, having launched in 2010 to prepare for the shift away from physical SIMs. Today it operates as a mature app-first eSIM provider with global and regional plans covering 190+ countries, built on a decade of roaming experience.

Long tenure in the space translates to stable app UX and deep carrier relationships. GigSky works well for travelers seeking a proven, established option.
