How to Install and Activate a SIMZY eSIM on iPhone

Setting up a SIM card or eSIM, to use on your iPhone is much easier and can save you money. Instead of carrying a physical card, an eSIM is a digital SIM embedded in your device that allows you to connect to a local telecommunications network digitally.

If you like your phone number and don't want to give it up, you can keep your regular mobile service on one SIM and use an additional internet line through a physical SIM or the second SIM slot on your iPhone. A SIMZY travel data eSIM helps you set up your network details ahead of time, so you can be up and running with high-speed internet as soon as you arrive at your destination.

What is Dual SIM Technology and How Does It Work on iPhone?

Dual SIM allows your device to use more than one SIM and/or eSIM simultaneously, connecting to two different networks. On iPhone XR and newer models, Dual SIM gives you flexibility to:

Separate Voice and Data:

Use your primary home line for calling and texting while routing all mobile data through your SIMZY eSIM.

Keep Work and Personal Numbers Separate:

Maintain one number for business calls and another for personal use on a single device.

Store Multiple eSIMs:

Keep multiple eSIM profiles saved on your device and easily activate the relevant plan when you travel.

Is Your iPhone eSIM-Compatible and Unlocked?

Before purchasing an eSIM, confirm that your iPhone meets two simple requirements:

Check for eSIM Compatibility:

Go to Settings > Mobile Data (or Cellular). If you see the option to Add eSIM, your iPhone supports eSIM.

Check Carrier Lock Status: Go to Settings > General > About, scroll down to Carrier Lock, and confirm that it reads No SIM restrictions. Your iPhone must be carrier-unlocked to use travel data plans.

Supported Models: Compatible with iPhone XR, XS, XS Max, iPhone 11, 12, 13, 14, 15, 16, and 17 series, as well as iPhone SE (2nd and 3rd generation) running iOS 12 or later. Note that iPhones manufactured for mainland China feature dual physical SIM slots and do not support digital eSIMs.

Critical Pre-Installation Rules: Wi-Fi and Home Country Setup

Active Wi-Fi Connection Required:

Downloading an eSIM profile requires an active internet connection to download carrier provisioning files. Complete the installation while connected to a stable Wi-Fi network at home.
