If you’re unsure where to locate your SIM details, this guide on how to find SIM number on iPhone can save you time and frustration. Your SIM number, also called the ICCID, is crucial for activating service, troubleshooting issues, or transferring your number to a new carrier.

1. What is a SIM Number on iPhone?

A SIM number on iPhone, also known as the ICCID (Integrated Circuit Card Identifier), is a unique code assigned to your SIM card or eSIM. It helps carriers identify your mobile account and connect your device to their network.

This number is different from your phone number or IMEI and is often required for activation, troubleshooting, or transferring service.

2. How to Find SIM Number on iPhone (Step-by-Step)

If you’re wondering how to find SIM number on iPhone, the process is actually quick and straightforward.

Your SIM number (ICCID) can be accessed directly from your device settings or by checking the physical SIM card. Below are the most reliable methods you can use.

Method 2: Check the physical SIM card

If you’re using a physical SIM, the ICCID is printed directly on the card:

  • Power off your iPhone
  • Use a SIM ejector tool to remove the SIM tray
  • Take out the SIM card carefully
  • Look for a long number printed on the card (this is your ICCID)

Method 3: Use your carrier app

Many US carriers provide SIM details inside their apps:

  • Open your carrier’s app
  • Log in to your account
  • Navigate to Account or Device Info
  • Find your SIM or ICCID details listed

Method 4: Check original SIM packaging

If you still have your SIM packaging, look at the card holder your SIM came in; the ICCID is usually printed on the back

3. Where to Find SIM Number on Different iOS Versions

Apple occasionally updates the Settings interface, which can make things look different even though the process remains similar.

Here’s how to locate your SIM number across different iOS versions.

iOS 17 and iOS 18 (Latest Versions)

On newer iOS versions, Apple has kept things simple and consistent. The ICCID is easy to locate within the About section:

  • Go to Settings
  • Tap General
  • Select About
  • Scroll down to find ICCID

You may also see multiple ICCIDs if you’re using dual SIM or multiple eSIM profiles.

iOS 14 to iOS 16

For slightly older versions, the steps are nearly identical, though the layout may feel a bit less modern:

  • Open Settings
  • Tap General
  • Select About
  • Scroll until you see ICCID

In these versions, the SIM details are grouped with other device identifiers, such as the IMEI and serial number.

iOS 13 and Earlier

On older iPhones running iOS 13 or below, the ICCID is still accessible, but the interface may look different:

  • Open Settings
  • Tap General
  • Select About
  • Scroll down to locate ICCID

In some cases, the text may appear smaller or less organized compared to newer versions, but the information is still there.

Key differences to note

While the steps are mostly consistent, here are a few differences across versions:

  • Newer iOS versions display multiple SIM profiles more clearly
  • Older versions may not label eSIM as clearly
  • The layout and design of the About section may vary
