How to Find Your IMEI and eSIM Information (2026 Guide)

 

If you're switching to a new wireless carrier like Total Wireless, activating an eSIM, or checking whether your phone is compatible, you'll often be asked for your IMEI number or eSIM information.

In this guide, you'll learn what IMEI and eSIM are, how to find them on both iPhone and Android devices, and why they're important before switching carriers.

What Is an IMEI Number?

IMEI stands for International Mobile Equipment Identity.

An IMEI is a 15-digit identifier for a mobile device. A dual-SIM phone may display more than one IMEI, such as IMEI1 and IMEI2.

Wireless carriers may use your IMEI to:

• Check device and network compatibility
• Confirm activation eligibility
• Identify your device during customer support
• Screen devices reported lost or stolen

What Is an eSIM?

An eSIM (Embedded SIM) is a digital SIM built directly into your smartphone.

Unlike a physical SIM card, an eSIM can be activated electronically without inserting a SIM card.

Benefits include:

  • No physical SIM required
  • Faster activation
  • Easily switch between carriers
  • Support for multiple phone plans

How to Find Your IMEI on an iPhone

Method 1: Settings

Go to:

Settings → General → About

Scroll down until you see:

  • IMEI
  • IMEI2 (if available)
  • EID (for eSIM)

Method 2: Dial a Code

Open the Phone app and dial *#06#. On many phones, the IMEI information will appear on the screen. This method may vary by device or carrier.

How to Find Your IMEI on Android

Open Settings and tap About phone. Look for IMEI or IMEI information. If it is not visible, use the search box in Settings and search for “IMEI.”

Menu names vary by manufacturer and software version. On many Android phones, you can also dial *#06# to display the IMEI information.




How to Check If Your Phone Supports eSIM

iPhone

Apple states that iPhone XS, iPhone XS Max, iPhone XR, and later models support eSIM. Availability may vary by country or region and wireless carrier.

To check your iPhone, go to Settings → Cellular (or Mobile Service). If you see Add eSIM, your device has eSIM settings. Before activation, confirm that your carrier supports your exact model and plan.

Android

eSIM support on Android phones varies by manufacturer, model, software version, country or region, and wireless carrier.

Check your phone’s Settings for an option such as Add eSIM, Add mobile plan, or Download a SIM. Menu names may vary by device. Before activation, enter your IMEI in your carrier’s official compatibility tool.

What Is an EID?

EID stands for eUICC Identifier. It is a unique identification number assigned to the embedded SIM hardware in an eSIM-capable device.

Some wireless carriers may request the EID during eSIM activation or troubleshooting.

On an iPhone, you can usually find it under Settings → General → About. On Android phones, menu names vary, but the EID may appear under Settings → About phone → SIM status.

Why Do You Need Your IMEI?

You'll usually need your IMEI when:

  • Switching to Total Wireless
  • Checking phone compatibility
  • Activating eSIM
  • Unlocking your phone
  • Transferring your number
  • Requesting technical support

Frequently Asked Questions

Can two phones have the same IMEI?

No.

Every mobile phone has its own unique IMEI number.

Is it safe to share my IMEI?

Only share your IMEI with your wireless carrier or trusted customer support.

Avoid posting your IMEI publicly online.

Can I activate eSIM without an IMEI?

Requirements vary by carrier and device. Many carriers request an IMEI, IMEI2, or EID during eSIM activation. Check the carrier’s activation instructions to confirm which number is required.

Does every phone support eSIM?

No.

Older smartphones may only support physical SIM cards.

Final Thoughts

IMEI, IMEI2, and EID identify different parts of your phone’s cellular hardware. Before switching carriers or activating an eSIM, confirm which identifier is required and check your device through the carrier’s official compatibility tool.

Keep these identifiers private and share them only with your wireless carrier or trusted customer support.

  How I Compare Affordable Phone Plans When comparing affordable phone plans, I look beyond the advertised monthly price. I also consider the network used, hotspot allowance, international features, number of lines, device compatibility, and whether the lowest price requires Auto Pay or a multi-month commitment. A plan that looks cheapest at first is not always the best value for every customer. Before switching, I recommend checking the total monthly cost and coverage in the places where you actually use your phone most.

How to Check If Your Phone Is Unlocked Before Switching Carriers (2026 Guide)

Why I Check the Unlock Status First Before switching carriers, I recommend checking the phone’s unlock status before doing anything else. A phone number may be eligible to transfer, but that does not necessarily mean the phone itself is ready to work with another carrier. Checking the unlock status, IMEI compatibility, and eSIM or SIM support in advance can help prevent activation problems and unnecessary delays during the switch.  If you're planning to switch to a new wireless carrier like Total Wireless , Verizon , Visible , or another provider, one of the first things you should check is whether your phone is unlocked . An unlocked phone allows you to use SIM cards or eSIMs from different carriers.  If your phone is still locked, your number may still transfer, but the device may not activate on the new carrier’s network. What Is an Unlocked Phone? An unlocked phone is a device that can be used with almost any compatible carrier. A locked phone only works with the ca...
