Apple’s iPhone Handoff feature will cost you $5 a month on T-Mobile
Apple is introducing a feature called iPhone Handoff with iOS 27, allowing a single eSIM phone number to be shared across two iPhones without using them simultaneously. However, T-Mobile in the US has confirmed it will charge subscribers an extra $5 a month to access the feature, adding a fee to what Apple is positioning as a convenience upgrade. The tool will initially roll out to T-Mobile customers in the US and Deutsche Telekom customers in Germany, with wider availability likely to follow.
With Handoff enabled, users can switch which of their two iPhones is active at any time, and calls, voicemail, messages, Find My, iCloud data and third-party app data will sync automatically to whichever device is in use. Setup is done via the Cellular section in Settings, either on an existing device or when activating a new iPhone, and both handsets must run iOS 27 and share the same Apple ID. iOS 27 is set to launch on 14 September.

Apple's Handoff feature lets someone use two iPhones with one phone number, switching which handset is "live" without needing two SIM plans. It works over eSIM, the digital version of a phone's SIM card, and syncs calls, texts, voicemail and app data automatically to whichever iPhone is in use at the time. It arrives with iOS 27, Apple's next operating system update, due out on 14 September.
The feature depends on cooperation from mobile networks, since they control how phone numbers and eSIMs are provisioned. T-Mobile in the US and Deutsche Telekom in Germany are the first carriers offering it, meaning other networks and countries will likely need to add support before their customers can use it.
The story centres on T-Mobile's decision to charge an extra $5 a month for access to Handoff, despite Apple building the feature into iOS at no extra cost. This raises a broader question about who benefits financially when tech companies add new capabilities to phones, since carriers can choose to charge separately for features that rely on their networks.
Both sides, in good faith
The strongest fair case each way — we don't pick a winner.
The case for
Advocates of the fee argue that carriers incur genuine technical and infrastructure costs to support eSIM handoff between two devices, including network signalling, provisioning and customer support, and that pricing it as an optional add-on lets casual users avoid subsidising a feature they don't need. They would also point out that consumers retain choice: nobody is forced to buy a second iPhone or pay the surcharge, and $5 a month is a modest sum for a genuine convenience upgrade, comparable to other optional carrier add-ons like multi-device data plans.
The case against
Critics argue that a feature built into Apple's own operating system and marketed as a core convenience should not become a fresh revenue line for carriers, especially when the underlying technology (eSIM switching) already exists on the network with minimal marginal cost per user. They would contend that charging extra erodes the value of an iOS upgrade customers already paid for indirectly through their device or plan, and that it risks setting a precedent where software-level Apple features are monetised piecemeal by network operators, disadvantaging households who already own multiple iPhones and simply want seamless continuity between them.
