You don’t have to struggle with eSIM switching anymore — Android and iOS finally work together to make the process seamless. Here’s how I do it.

I haven’t been shy about my hatred for eSIM, the digital technology that stores SIM information on your device rather than on a separate SIM card. One of the occupational hazards of my job is that I’m always switching phone lines between iOS and Android phones. Ever since Apple and Google shifted to selling eSIM-only phone models, it has been painstakingly difficult. I’d have taken a 50% success rate, but my luck with transferring eSIMs between iOS and Android felt more like an unrelenting struggle.

If you’ve had similar eSIM hardships, trust me, I believe you. With that being said, I’m thrilled to report that Apple and Google have finally figured out cross-platform eSIM transfers. This isn’t exactly a new feature — it was first announced at last year’s WWDC — but it required software updates to work. In other words, the joint feature wouldn’t do users much good until the general public widely adopted iOS 26 and Android 16.

It feels like we’re there because I’ve been transferring eSIMs at least once a week for months, and I haven’t set foot in an AT&T store once. This is how you can quickly and easily transfer eSIM data from an iPhone to an Android phone, or from an Android phone to an iPhone, without calling your carrier or going to a store.

For years, iOS and Android didn’t play nice

The technology behind eSIM isn’t bad — the reality is quite the opposite. While physical SIM cards are easier to transfer between devices, this enables security vulnerabilities like “SIM swapping.” This attack involves stealing a locked phone, removing the physical SIM card, and inserting it into another device, where hackers can intercept things like two-factor SMS codes. Additionally, eSIMs are easier to purchase on a whim. You can buy a travel eSIM online and load it onto your phone in minutes.

Unfortunately, the infrastructure just wasn’t there to support easy eSIM switching before. Transferring from…
