Setting up an eSIM on iPhone is straightforward and takes under five minutes once you have your QR code from your provider. All iPhones from the iPhone XS and XR (2018) onwards support eSIM, and US-market iPhone 14 models onwards are eSIM-only with no physical SIM slot.
Here's the exact step-by-step process, plus what to do if something goes wrong.
Before You Start
- Confirm your iPhone is eSIM-compatible: XS, XR, 11, SE (2nd/3rd gen), 12, 13, 14, 15, 16 series all support eSIM.
- Your iPhone must be carrier-unlocked. If you bought it on a payment plan or through a carrier, confirm it's unlocked (Settings > General > About > Carrier Lock — should say "No SIM Restrictions").
- Have your eSIM provider's QR code ready — either on another device's screen or printed.
- You'll need a Wi-Fi connection for the initial download, so do this before your flight or use airport Wi-Fi.
Installing Your eSIM — QR Code Method
Go to Settings on your iPhone home screen.
Tap "Cellular" (or "Mobile Data" depending on your region and iOS version).
Tap "Add Mobile Plan" (or "Add Cellular Plan" / "Add eSIM"). A QR code scanner will open.
Hold your iPhone camera over the QR code from your eSIM provider. The code will be detected automatically. If you are using the same device to view the code, use another device or print it out — you cannot scan a code on the same screen.
Your iPhone will show the plan name and carrier. Tap "Continue" to confirm you want to add this plan.
iOS will ask you to label the plan (e.g., "Travel," "Europe," "Yesim"). This helps you distinguish it from your regular SIM.
Choose whether to use the eSIM as your primary data line. For travel, select the new eSIM as "Default Line" for data when prompted, or go to Settings > Cellular > Cellular Data and switch to the new plan.
Manual Activation (No QR Code)
Some providers give an activation code instead of a QR code. After tapping "Add Mobile Plan," tap "Enter Details Manually" and type in the SM-DP+ Address and Activation Code from your provider's confirmation email.
📶 Get Your Travel eSIM
Once your iPhone is ready, grab a Yesim travel eSIM — buy online, scan the QR code in Settings, and land with working data.

Troubleshooting
- "Unable to complete activation" — ensure you are connected to Wi-Fi and try restarting your iPhone, then repeat the scan.
- "This plan is already in use" — the QR code may be single-use; contact your provider for a new one.
- eSIM installed but no data — go to Settings > Cellular > Cellular Data and confirm the new eSIM is selected. Also check Settings > Cellular > [Plan Name] > "Turn On This Line."
- Carrier Lock message — your phone is still locked to your original carrier; contact your carrier to unlock it before using a travel eSIM.
- Plans stay for future trips — each installed eSIM plan stays in settings unless you delete it, so you can reactivate the same plan on a return visit if it has remaining data or validity.
