EID Number: Causes and Fixes

You want to activate a travel data plan. Your carrier asks for a 32-digit EID number. You have no idea where to find it. You type a random number from your settings. The activation fails. You land at your destination with zero data. AT&T charges you $15 a day for basic roaming.

Finding your EID number should take ten seconds. This guide shows you exactly where to look. You will learn how to bypass manual setup errors. You will also discover how to connect to a foreign phone network without typing long serial numbers.

Why does this problem happen?

EID stands for Embedded Identity Document. It is a unique 32-digit serial number. This code identifies the eSIM chip soldered into your smartphone.

Every device with an eSIM has an EID. Apple, Samsung, and Google use this standard.

When you buy a standard travel plan, carriers need this number. They use the EID to link your new profile to your specific device. If you provide the wrong number, the profile goes nowhere. Your phone displays a network unavailable error.

Manual eSIM configuration causes massive headaches. Typing 32 digits on a small screen invites typos. One wrong digit ruins the setup. You end up with a connection problem abroad.

A physical SIM card can break. An eSIM relies on the EID and cannot physically break. If your phone cannot read a physical card, check our guide to a damaged SIM card.

Carriers use different identifiers. People often confuse them.

• EID: 32 digits. Identifies the permanent eSIM hardware.
• IMEI: 15 digits. Identifies the phone itself on the network.
• ICCID: 20 digits. Identifies the active SIM profile.

You only need the EID to download a new eSIM profile manually.

Quick fix (solves 80% of cases)

You can locate your EID number in seconds. You do not need an internet connection to find it.

Method 1: The Dialer Code This works on almost all modern smartphones.

1. Open your phone app.
2. Open the dialer keypad.
3. Type *#06#.
4. A screen pops up instantly. Look for the 32-digit number labeled "EID".

Method 2: iPhone Settings

1. Open Settings.
2. Tap General.
3. Tap About.
4. Scroll down to the bottom. The EID number is listed there.
5. Long-press the number to copy it.

Method 3: Android Settings

1. Open Settings.
2. Tap About Phone.
3. Tap Status information.
4. Scroll down to find the EID.
5. Copy the number to your clipboard.

If your device displays an EID, it supports eSIM technology. If your phone says no SIM, finding your EID confirms your hardware is ready. See the no-SIM message for next steps.

Pass this 32-digit code to your carrier. They will push the eSIM profile to your device.

Advanced solutions

Sometimes, finding the EID number does not solve the problem. You might face deeper mobile troubleshooting travel issues.

The EID is missing from settings If dialing *#06# shows an IMEI but no EID, your phone lacks an eSIM chip. Older models only support physical SIM cards. You cannot use an eSIM. You must buy a physical local SIM or use Wi-Fi.

The EID is locked by your carrier You bought your phone on a contract from Verizon or AT&T. They might lock your device. A locked phone cannot use a foreign phone service. Even if you provide the correct EID, the new profile will fail to install.

1. Call your home carrier.
2. Ask them to unlock your device for international travel.
3. Wait for the unlock confirmation before adding a new plan.

Manual setup requires more data Some carriers ask for more than the EID. They require an SM-DP+ address and an activation code. If manual setup fails, you might need server details. Read our guide on the SM-DP+ activation server to resolve this. You can also compare the ICCID number and learn where to find your EID.

Roaming remains disabled You gave the carrier your EID. The profile installed successfully. But you still have no data.

1. Go to Settings > Cellular.
2. Select your new travel line.
3. Turn on Data Roaming.
4. Restart your phone.

A reboot forces the device to read the EID and register on the local network. If data still fails, app settings might be blocking access. Check our guide on managing app data abroad.
