“iPhone Handoff” arrives with iOS 27: now we’ll be able to use two phones with the same number

With iOS 27 comes a very interesting feature for those of us who alternate between two iPhones: iPhone Handoff will let us use both phones with the same number and switch between them seamlessly. A system that adds a lot of flexibility for those of us who work with several devices and that relies on eSIM technology to make a setup that’s becoming increasingly common easier.

One main iPhone and another as a companion

We’ll be able to set it up from the Settings app, under Mobile Data. Here we’ll choose which will be our main iPhone and which will act as the companion. According to MacRumors, the main eSIM will stay on the first phone and it will be the second one that gets a linked eSIM.

Once we’ve activated the feature, we’ll manage all phone settings from the main iPhone, while shared location will automatically be tied to whichever device is using the number at that moment. The system does, of course, have a couple of requirements.

The first is, of course, updating our phones to iOS 27, but the second is carrier support for the feature. As far as we know, T-Mobile and Deutsche Telekom already appear to be among the first carriers to offer this service, but we’ll have to see how the list shapes up with the launch of iOS 27 and afterward.

With the launch of iOS 27 scheduled for just a few weeks from now, we should soon discover more details about this feature. One that can completely change how we choose which iPhone to carry and use at any given moment.
