A small but significant condition of the Justice Department approving Sprint and T-Mobile's merger is that the combined entity — and Dish, which is being turned into a fourth national carrier — must support eSIM technology.
GigSky is a mobile cell service provider with a history of catering to Apple users, providing service in more than 190 countries. When they announced their eSIM for iPhone XS, iPhone XS Max, and iPhone XR, AppleInsider gave it a shot.
As carriers continue to add support for Apple's eSIM technology, using apps from the App Store to get the second number set up is also an option. AppleInsider walks you through how to use the Gigsky app to start using eSIM without having to shlep to a carrier's local store.
In preparation of a wide public launch expected before the end of the year, T-Mobile on Thursday previewed eSIM activation app for iPhone that will allow iPhone XS and XR owners to configure a second line on their device without visiting a retail store.
Apple's new dual SIM feature, available with iPhone XS and XR models, was activated with iOS 12.1 on Tuesday, but the three biggest cellular carriers in the U.S. are not supporting the feature at launch.
