Does iPhone 11 Have eSIM?

Yes. iPhone 11 supports eSIM, which means you can use a digital SIM alongside a physical nano-SIM. This enables Dual SIM functionality (two numbers on one phone), depending on your carrier.

You can use:

  • One physical SIM + one eSIM (most common)
  • Dual SIM with different carriers (if supported)
  • A local eSIM while keeping your main SIM active (great for travel)

What You Need Before Activating eSIM on iPhone 11

  • A stable Wi-Fi connection (recommended)
  • One of the following from your carrier:
    • QR code (most common)
    • Carrier app activation
    • Manual activation details (SM-DP+ address + activation code)

Also check your iPhone:

  • Go to Settings → General → About
  • Make sure iOS is updated (Settings → General → Software Update)

  4. Scan your carrier’s QR code
  5. Follow the on-screen steps to complete activation

  2. Sign in
  3. Choose eSIM activation
  4. Follow the prompts

Method 3: Enter eSIM Details Manually

  1. Go to Settings → Cellular

How Dual SIM Works on iPhone 11 (Physical SIM + eSIM)

Once your iPhone 11 eSIM is active, your phone can run two numbers at the same time.

You can choose:

  • Which line is used for calls
  • Which line is used for iMessage/FaceTime
  • Which line is used for mobile data

To manage this:

  • Go to Settings → Cellular
  • Tap each plan and set:
    • Default Voice Line
    • Cellular Data
    • Allow Cellular Data Switching (optional)

Pro tip: Name your plans (e.g., “Work” and “Personal”) so it’s easier to select the right line when calling or texting.

Using iPhone 11 eSIM for Travel

Travel is one of the best reasons to use eSIM. You can keep your primary SIM active (for OTPs, banking SMS, WhatsApp) and add a travel eSIM for data.

Best setup for travel:

  • Physical SIM = your main number
  • eSIM = local/travel data plan
  • Set Cellular Data = eSIM line
  • Keep Voice on your main line

This avoids swapping SIM cards and reduces the risk of losing your primary SIM.

1) “Unable to Activate eSIM”

Try:

  • Restart your iPhone

  • Update iOS
  • Try scanning the QR code again

2) “Add Cellular Plan” Option Missing

Possible causes:

  • Your iPhone is restricted by region/carrier policies

4) Data Not Working on eSIM

How to Remove an eSIM from iPhone 11

If you’re switching providers or removing a travel plan:

  1. Go to Settings → Cellular
  2. Tap your eSIM plan
  3. Tap Remove Cellular Plan

Tip: Removing an eSIM deletes it from your phone. If you want to use it again later, you may need a new QR code from the carrier.
