Apple Insider Reviews GigSky eSIM Service for iPhone XS, XS Max, XR

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.

You may not have heard of GigSky, but they aren’t new; they’ve been around since 2010. In 2015, the firm began offering support for the Apple SIM for iPads, a SIM Apple provides which lets you select providers from within iOS.

From the very beginning, they’ve placed an emphasis on providing service for international travelers, and the eSIM offering fits right in that niche.

What it is

The iPhone XS, iPhone XS Max, and iPhone XR are equipped with an eSIM.

A SIM card contains the SIM chip, essentially a very small computer that is programmed with all the carrier’s settings to enable phone service. With most modern phones, you have to insert a SIM to activate mobile phone service.

The eSIM, or embedded SIM, is that same functionality as a programmable computer built into the iPhone.

The advantage of doing this is that it saves space in the phone: you don’t need to have physical space for the physical card, you don’t need the contacts inside to receive it, you don’t need the ejector mechanism, which means Apple can use that interior space for something else.
