Setting up an eSIM on your iPhone is easier than you might think. In just a few minutes, you can have a fully working data plan activated digitally — no plastic SIM card, no PIN ejector tool, and no waiting for a delivery. This guide walks you through the complete iPhone eSIM setup process for all supported models.
Which iPhones Support eSIM?
Before you start, confirm that your iPhone model supports eSIM. Apple introduced eSIM support starting with the iPhone XS. Here is a full list of compatible models:
- iPhone XS, XS Max, XR (2018) — eSIM supported with physical SIM dual SIM
- iPhone 11, 11 Pro, 11 Pro Max (2019)
- iPhone SE (2nd gen) (2020)
- iPhone 12 series (2020)
- iPhone 13 series (2021)
- iPhone 14 series (2022) — US models are eSIM-only (no physical SIM tray)
- iPhone 15 series (2023)
- iPhone 16 series (2024)
- iPhone SE (3rd gen) (2022)
Important: Your iPhone must be carrier-unlocked to use a third-party travel eSIM. If your phone is locked to a specific carrier, contact them to request an unlock before purchasing a travel eSIM.
How to Install eSIM on iPhone Using a QR Code
The most common method to activate an eSIM on iPhone is via a QR code provided by your eSIM carrier. Here is the step-by-step process:
Step 1: Purchase Your eSIM Plan
Go to eSIM-X and choose a data plan for your destination. Select the country or region you are traveling to, choose your preferred data package (e.g., 5GB for 15 days), and complete the purchase. You will receive a QR code by email within minutes.
Step 2: Open iPhone Settings
On your iPhone, go to Settings. Then tap Mobile Service (or Cellular depending on your region). You will see an option to Add eSIM or Add Mobile Plan. Tap it.
Step 3: Scan the QR Code
Your iPhone camera will open automatically. Hold it over the QR code you received from eSIM-X. Your iPhone will recognize it and show a prompt. Tap Continue to begin the installation.
Tip: If the QR code is on the same device you are trying to scan from, use another phone or print the QR code first. Alternatively, most eSIM providers also offer a manual activation code.
Step 4: Label Your eSIM
iOS will ask you to give your new eSIM a label. You can name it something like “Travel eSIM” or “Europe Data” to keep things organized, especially if you use dual SIM regularly.
Step 5: Set Default Data Line
After installation, iOS will ask which line to use for mobile data. Select your new travel eSIM as the data line. You can keep your primary SIM active for calls and texts, while the eSIM handles all data traffic. This is the power of dual SIM on iPhone.
Step 6: Turn On Data Roaming (if needed)
Some eSIM plans require you to enable Data Roaming for the eSIM line. Go to Settings > Mobile Service > Your eSIM Label > Data Roaming and turn it on. This is normal for international travel plans and does not mean you will be charged extra roaming fees — the flat rate is already included in your eSIM plan.
How to Add eSIM on iPhone Without a QR Code
Some carriers support eSIM Carrier Activation directly without a QR code. This is common for major telecom providers in your home country. When you get a new iPhone, the carrier may automatically push your eSIM during setup. For travel eSIMs, a QR code or activation code is the most common method.
If your provider gives you an activation code instead of a QR code, tap Enter Details Manually after opening the Add eSIM screen. You will be asked to input the SM-DP+ Address and the Activation Code.
How to Manage Multiple eSIMs on iPhone
Your iPhone can store multiple eSIMs, but only two can be active at the same time (one physical SIM + one eSIM, or two eSIMs on newer models). To manage your eSIMs:
- Go to Settings > Mobile Service to see all lines
- Tap any line to turn it on or off
- Change the default data, call, or SMS line at any time
- Delete an eSIM by tapping its label and selecting Remove This Plan
Note: Once you delete an eSIM from your iPhone, it is permanently removed and cannot be reinstalled. Make sure you no longer need it before deleting.
iPhone eSIM Setup: Common Issues and Fixes
QR Code Not Scanning
Make sure the QR code is well-lit and not blurry. If it still does not work, try requesting the manual activation code from your eSIM provider and enter it manually.
eSIM Installed But No Data
Check that the eSIM is set as the default data line in Settings. Also enable Data Roaming for the eSIM line. If you still have no data, try toggling Airplane Mode on and off to force a network refresh.
“This Plan Cannot Be Added” Error
This usually means your iPhone is carrier-locked. Contact your home carrier to unlock the device before trying to add a third-party eSIM.
eSIM Showing as “Not Active”
Some travel eSIMs only activate when you arrive in the destination country. Check the plan details for the activation start date, or contact your eSIM provider’s support team.
iPhone eSIM vs Physical SIM: What Is the Difference?
An eSIM is a digital SIM embedded inside your iPhone. It works exactly like a physical SIM card, but you activate it digitally and can switch between plans without ever opening your phone. The key advantages for travelers are speed (instant activation), convenience (no card swapping), and the ability to maintain your home number while using a local data plan.
Frequently Asked Questions
Can I use eSIM and my regular SIM at the same time on iPhone?
Yes. iPhone supports Dual SIM functionality. You can have your physical SIM for calls and SMS and your eSIM for data. Set the eSIM as the data-only line and your physical SIM for everything else.
How many eSIMs can I store on my iPhone?
iPhone 13 and earlier can store up to 5 eSIMs but only activate 1 at a time (plus 1 physical SIM). iPhone 14 and later with iOS 16+ can store more eSIMs and supports dual eSIM without a physical SIM tray in US models.
Does setting up eSIM on iPhone cost anything extra?
No. Setting up an eSIM on iPhone is free. You only pay for the data plan itself. There is no hardware fee, no activation fee from Apple, and no SIM card cost.
Can I transfer my eSIM to a new iPhone?
Travel eSIMs from third-party providers typically cannot be transferred between devices. If you upgrade your iPhone, you will need to purchase a new eSIM plan for your next trip. Your home carrier eSIM can usually be transferred using iPhone-to-iPhone transfer during setup.
Download the eSIM-X App
The eSIM-X app makes iPhone eSIM setup even easier. Browse plans, scan QR codes, manage your data, and get real-time support — all in one place.
Setting up an eSIM on your iPhone takes less than five minutes. Whether you are preparing for a Europe trip, heading to Southeast Asia, or just want a backup data plan, the process is the same. Buy your plan, scan the QR code, set your data line, and go. That is all there is to it.
