T-Mobile iPhone Handoff fee: What it is, how it works

Big corporations exist to make money, and T-Mobile is making that very clear with its application of one new iOS 27 feature.

At Apple 's big iPhone launch event this week, the company announced a feature called iPhone Handoff, which is coming with the latest iOS update.

The feature will allow eSIM users to use the same phone number on two iPhones and choose which device is active at any given time.

The active phone can receive calls, texts, and other cellular communications.

It'll only be available to T-Mobile customers in the U.S. at first, and that's where things get interesting: T-Mobile announced on its website that the feature will cost $5 per month.

Here’s what surprised me most So, in other words, you can buy an iPhone Duo and an iPhone 18 Pro and switch between them whenever you want without much hassle, aside from adding an extra $5 to your T-Mobile bill every month.

How to set up the iPhone Handoff feature Activating one phone is seemingly as simple as unlocking it, but you can't use them both for texting, calling, etc., at the same time.

To set it up, go to the eSIM section of the Settings app, tap Phone, tap Continue, then tap Transfer.

If it works, you'll get a message saying a device has been activated when you unlock it.

It's unfortunate that this feature is only available to T-Mobile customers stateside right now, and that T-Mobile is taking advantage of that fact to charge a small fee to use it.

But, at the very least, it does sound reasonably intuitive.
