We've all seen the technology of one phone, two SIMs, but what if two phones could be used with a single SIM card or number? You might think this is impossible, but it's happening. You'll be surprised to read this news. This means there's no need to recharge the SIM card separately. Furthermore, there's no need to turn on the hotspot on one phone to use the internet on the other.
How surprising, now you will say which company is making this new technology. Your curiosity to know this must have reached its peak. Don't worry, without any delay, we are giving you all the information in this article. So, Apple is preparing to bring a feature called 'Handoff' with 'iOS 27'. With its help, the SIM card of one iPhone can be used on another iPhone. This feature will work exactly like the way Apple Watch works with iPhone right now. Because of this, there will be no need to get separate SIM cards for different iPhones.
This feature is likely called 'iPhone Handoff.' Apple teased this feature with iOS 27 during its WWDC event in June 2026. Now, a video reported by MacRumors and a simulation in Xcode 27 has revealed how this feature actually works. According to reports, this feature allows users to use the same active mobile number on two different iPhones.
How to set it up?
Enabling this feature is very easy. To do so, go to the 'Cellular' section in 'Settings'.
Then, tap on 'iPhone Handoff' and select your main phone as 'Main iPhone'.
This will keep your primary eSIM and all main network-related settings active on this device.
Now, you need to pair your second iPhone as a 'Companion iPhone'.
The system will automatically install a companion eSIM on this second device.
This works just like a smartwatch paired with a phone's SIM card. This allows you to use calling and internet services without inserting a physical SIM card.
What is the benefit of this feature?
The biggest advantage of this feature is that users will be able to easily switch between the two devices at any time; there will be no need to manually reconnect or replace the SIM card (SIM swap).
Also, there will be no need to use one phone as a hotspot to use the internet on another phone.
To use both the phones, you will not need to buy separate SIM cards or take different recharge plans.
An important feature of this system is that SIM cards are not cloned; all control remains with the primary phone. As a result, the primary iPhone retains control over cellular data and network settings.
