Does iPhone 15 have Dual SIM Support?

Yes, the iPhone 15 series, including the iPhone 15, iPhone 15 Plus, iPhone 15 Pro, and iPhone 15 Pro Max, maintains support for physical SIM cards in international markets. These models are designed to work seamlessly with nano-SIM cards in countries like the U.K., France, Germany, Italy and Spain, among others.

In addition to physical SIMs, most of these regions also offer compatibility with eSIM technology. This enables users to enjoy dual-SIM functionality, allowing for seamless connectivity with cellular networks.

Apple's decision to retain the SIM card tray outside of the U.S. contrasts with the previous iPhone 14 series, where the SIM card tray was replaced with eSIM functionality in the U.S. Apple's support for eSIMs stems from their enhanced security features, making them impervious to removal in cases of lost or stolen iPhones.

Moreover, Apple provides a comprehensive list of global carriers supporting eSIM technology, facilitating easy activation of cellular plans without the need for a physical nano-SIM card.

Users can manage up to eight eSIMs directly from the iPhone's Settings app, streamlining the process of switching between carriers. Notably, iPhone 13 and newer models can accommodate two active eSIMs concurrently.

While eSIM adoption continues to grow, the presence of a physical SIM card tray in iPhones sold outside of the U.S. remains unchanged for now. It's possible that future iterations may see a shift away from physical SIMs, but for the time being, they remain a key feature in these devices.

How to set up and use dual SIM on iPhone

Now that you know about the different dual SIM technology for iPhones, let’s see how you can set up and use them.

Nano Sim + eSim Setup

Setting up a traditional nano-SIM is easy and self-explanatory, but setting up an eSIM is different. You can use both the nano-SIM and eSIM for different cellular plans.

The nano-SIM will be your primary SIM while the eSIM will be your secondary SIM. But in case you don’t have a nano-SIM then you can use only the eSIM, but your carrier has to support this feature.&nbsp,

To set up eSIM, follow these methods and their steps:

By Scanning the QR code

1. Open the Camera app on your iPhone and scan the QR code provided to you by your carrier.
2. A Cellular Plan Detected notification should appear, tap on it.
3. Tap on Continue, at the bottom of the screen.

If a confirmation code is asked to activate the eSIM, then enter the number that your carrier provided.

Use a carrier app

1. For this, open the App Store and download your carrier's app.

Install an assigned cellular plan

With iOS 13 and later, supported carriers can assign a cellular plan for you to install. Contact your carrier for more information on this.

You can find the Default Line setting under the Cellular or Mobile Data option. Choose your default SIM here.&nbsp,

Choose Preferred SIM for each contact&nbsp,

If you use a dual SIM, one for family/friends and one for work, you can choose a preferred SIM. For example, you can set your Primary SIM for your family and friends and you can use your secondary SIM for your work contacts. To do this,&nbsp,

Once this is done, you can use them by following the same steps that were used for the nano-SIM + eSIM combination. Labeling your SIM cards, setting a default number, choosing numbers, making calls, stitching between numbers, sending messages, and changing cellular data all work the same way.&nbsp,

Dual SIM 5G support on iPhones

When Apple launched the iPhone 12, it came out of the box with iOS 14.0. This version of iOS 14.0 didn’t support 5G connectivity in dual SIM mode. So out of the box, the iPhone 12 when using dual SIM cards, would default to only 4G connectivity.&nbsp,

This affected all iPhone units at launch. The issue was later fixed with a software update to iOS 14.5. So if you are facing trouble with 5G connectivity not working on your iPhone when using dual SIM, then you will have to update your iPhone to at least iOS 14.5 for it to work.&nbsp,
