how to enable dual sim on iPhone

What is Dual Sim?

Dual Sim technology is a relatively new development in cellular technology that allows users to have two active phone numbers on the same device. It’s great for those who travel frequently and want access to two phone plans without having to carry around two phones. With dual sim, you can combine work and personal lines into one device, or keep separate lines for business and pleasure.

The technology has been available on Android devices for some time now, but Apple recently announced that several of their new iPhone models will feature dual sim capabilities as well. This means iPhone users too can take advantage of using multiple phone numbers from a single device – it’s convenient, cost-effective and makes managing multiple accounts much easier. With dual sim enabled iPhones, you can easily switch between your preferred operators with just the tap of a button.

Sim-enabled iPhones are the latest trend in smartphone technology, allowing users to have two phone numbers simultaneously on one device. The dual sim feature has been available on Android devices for some time, but with the release of Apple’s new iPhone 11 Pro Max and iPhone XS Max, having two cellular plans on a single device is now possible with an iOS system.

Enabling dual Sims on your iPhone is relatively easy and only takes a few simple steps. Once you have obtained a physical SIM card from your carrier, all you need to do is activate it by going into Settings > Cellular > Add Cellular Plan and follow the instructions presented. After that step has been completed, both Sims can be used interchangeably for calls and data services without any issues or limitations.

Step 1: Check if Supported

The latest iPhones have shipped with dual sim support, allowing users to manage multiple lines at once. While this feature is available on most new devices, it’s important to check if your device actually supports dual sim before you try to enable it.

By finding out if your iPhone is supported for dual sim use, you can save yourself time and frustration. Many features come with iOS updates, so make sure that you are running the latest version of the operating system in order to get the best experience when using this feature. Additionally, Apple has stated that certain models of iPhones won’t be capable of using dual sim functions due to hardware restrictions.

To find out if your device is supported for dual sim use, take a look at Apple’s list of compatible devices or contact their customer service team for more information.

Step 2: Set Up eSIM

The second step in enabling dual SIM on iPhone is setting up an eSIM. An eSIM (embedded Subscriber Identity Module) is a digital SIM card that allows you to activate a cellular plan from your carrier without having to use a physical nano-SIM. With the introduction of iOS 12.1, iPhones now support dual SIM with one physical nano-SIM and one eSIM. This allows users to take advantage of multiple carriers without having to switch out their SIM cards every time they want to change carriers or access another network abroad.

Before you can set up your eSIM, make sure that your carrier supports it and that they have provided you with an activation code or QR code so that you can easily add it onto your device.

Now that you’ve identified your phone’s dual sim capabilities, it’s time to set up an eSIM. An eSIM is a digital SIM card stored inside your iPhone, allowing you to switch between different carriers without having to physically swap out the SIM card. Setting up an eSIM on an iPhone is easy and straightforward – here’s how you can do it. First, make sure that your cellular plan supports dual-sim technology by checking with your network provider.

Once confirmed, open the Settings app and navigate to “Cellular” then “Add Cellular Plan.” You will be prompted to enter a QR code or manual details from your carrier – if you have a QR code already, scan it and finish setup; if not, contact your carrier for help in obtaining it.


eSIM is a new technology that allows users to have dual SIM capabilities on their iPhone. It eliminates the need for physical SIM cards, allowing users to store and activate multiple mobile phone plans from a single device. This convenient feature is perfect for individuals who frequently travel or switch providers while keeping the same number.

Using an eSIM, it’s easy to enable dual SIM capabilities on your iPhone. All you need to do is open the Settings app and navigate to Cellular > Add Cellular Plan. From there, you’ll be able to scan a QR code or enter a code provided by your key service provider in order to activate two separate plans on your device. You can then decide which line will be used as your primary number and which one will act as your secondary or backup number.

Step 3: Use Dual SIM

For those who have recently purchased an iPhone, enabling dual SIM can help unlock a world of convenience. Dual SIM allows users to maintain both personal and business life on the same device, freeing up time and energy for more important activities. Instead of having to switch between two devices, dual SIM enables users to access different phone numbers with one iPhone.

This feature is especially useful for international travelers who want to stay connected while abroad without incurring high roaming fees or needing multiple physical phones in tow. With dual SIM enabled on their iPhones, they’ll be able to easily manage calls and texts from both their domestic as well as foreign networks without having to juggle multiple devices.

Step 4: Troubleshooting Tips

Troubleshooting can be a frustrating part of any technology, and enabling dual SIM on an iPhone is no exception. Even with the latest iOS updates, understanding how to set up two phone numbers on one device has been tricky for many users. Fortunately, there are some tips you can use to make sure your dual SIM setup goes smoothly.

First off, if you are having trouble setting up the second SIM card slot on your iPhone, check that it’s compatible with Apple’s Dual SIM system. Most new iPhones released in 2020 have Dual Sim capabilities built-in, but older models may not support this feature yet. If you need help determining whether or not your model is compatible with Dual Sim technology, check out Apple’s website for more information.

Step 5: iOS Updates

Updates is an important step to enable dual sim service on your iPhone. Keeping your device up-to-date with the latest iOS update ensures that you have access to the most recent features, including dual sim support. To ensure that you are running a compatible version of iOS for dual sim support, launch the Settings app and then select General > Software Update. If a new update is available, tap Download and Install. You may need to enter a passcode or Apple ID password before the software can be installed. Once installation is complete, restart your phone for the changes to take effect and check if dual sim service has been enabled. Updating your iPhone’s software helps keep it running smoothly while keeping it secure from potential threats, so make sure to regularly check for updates when they become available.


The conclusion of this article is that dual sim capabilities on iPhone are a great feature, and can be enabled with relative ease. For those with multiple phone numbers, or who travel between countries frequently, this feature can make life much easier. It can help you stay connected without the need to switch out physical SIM cards each time.

Enabling dual sim on an iPhone is not difficult. All you need to do is check your carrier’s website for compatibility, and then follow the simple steps outlined in this article for setting up eSIM and physical SIM cards. You should also ensure that your iPhone model has dual SIM support from Apple before attempting to enable it.
