I see an IMSI in the SIM Applications menu. Can I use that instead?

The number in the SIM Applications (STK) menu is usually a longer, mangled value, not a clean identifier, so it will not match. The simplest identifier to use is your ICCID from Settings > General > About. (Our support can also look you up by your clean 15-digit IMSI, also shown in Settings > General > About, if you ever only have that.)

What if I cannot find the ICCID on my phone?

Open your original purchase page, the invoice or your-eSIM-data link you were sent, or the My eSIMs screen in the PikaSim app, where the ICCID is shown with your QR code. If you no longer have those, use the live chat at pikasim.com/help and tell us what you bought, roughly when, and how you paid, and we can match your order.

Does the eSIM need to be active to see the ICCID?

The line needs to be turned on for its ICCID to appear in Settings > General > About on iPhone. It does not need to be your data or voice line, it just needs to be enabled. On Android, the eSIM should be installed and selected.

How to Find Your eSIM ICCID

Technical Guide • 4 min read

TL;DR

iPhone & iPad: Settings > General > About > scroll down. The ICCID is listed under each cellular line
Android: Settings > About phone > SIM status (or Network & internet > SIMs > your eSIM)
The eSIM line must be turned on for its ICCID to show
The "SIM Applications" menu shows a longer, mangled number, not a clean identifier, so use the ICCID from About instead
Don't confuse the ICCID with the EID (a different number, the chip's hardware ID)
No phone access? Your ICCID is on your purchase page or in the My eSIMs app screen

What Is the ICCID (and Why You Need It)

The ICCID (Integrated Circuit Card Identifier) is the unique serial number of your eSIM, usually 19 to 20 digits. It is how PikaSim identifies your specific eSIM to:

Check your remaining data and validity
Apply a top-up
Look up your eSIM in the live chat for troubleshooting

The ICCID is not your phone number, and it is not secret in the way a password is, but it is the key identifier we ask for when you want to manage an eSIM you already own.

iPhone & iPad

Open Settings
Tap General
Tap About
Scroll down. Under each active cellular line you will see a section with Network, Carrier, IMEI, and ICCID
The ICCID is your eSIM serial number. Press and hold it to copy

Multiple lines? If you have more than one eSIM or a physical SIM plus an eSIM, each line has its own ICCID, shown under that line's name (for example "Travel eSIM" or the country name). Match the ICCID to the line you want to manage.

The eSIM line must be turned on. If a line is switched off, its ICCID will not appear in About. Go to Settings > Cellular, tap the line, and enable Turn On This Line. It does not need to be your data or voice line, just enabled.

Android (Samsung, Pixel, OnePlus, Xiaomi, and more)

The exact path varies slightly by manufacturer, but it is almost always under "About phone" or the SIM/network section:

Open Settings
Tap About phone > SIM status (Samsung: Settings > About phone > SIM card status)
Or go to Settings > Network & internet > SIMs > tap your eSIM
Look for ICCID (sometimes labeled SIM serial number)

GrapheneOS / Pixel: Settings > Network & internet > SIMs > your eSIM, or Settings > About phone > SIM status. See our GrapheneOS eSIM guide for the full walkthrough.

Two Things People Confuse With the ICCID

The ICCID is NOT the EID

At the top of Settings > General > About (iPhone) you'll see an EID, a long 32-digit number. That is the hardware ID of your phone's built-in eSIM chip and it is the same no matter which eSIM is installed. It will not work to look up your eSIM.

The ICCID is the one shown lower down, under a specific cellular line. That is the number to use.

The "SIM Applications" menu is the wrong place. On phone-number plans, you may find a SIM Applications (SIM Toolkit / STK) menu showing things like "Current IMSI", "Time left", and "Expire date". The number there is usually a longer, mangled value (often 18 digits) rather than a clean identifier, so it will not match. Ignore that screen and read the ICCID from Settings > General > About instead. (Support can also find you by the clean 15-digit IMSI shown in About, if that is all you have.)

If You Can't Get to the Device

You don't need the phone in hand. The ICCID is also on the materials you received when you purchased:

Web purchase: open your original purchase confirmation page, or the invoice / your-eSIM-data link you were sent. The ICCID is shown next to your QR code
App purchase: open the My eSIMs screen in the PikaSim app. Every eSIM you've bought is listed there with its details

Lost the purchase page too? Because PikaSim is account-free and we don't collect emails, we verify ownership by what you can tell us about the order. Use the live chat at pikasim.com/help and say what you bought (country/plan), roughly when, and how you paid (card or crypto, and the amount). We can match it to your order and help from there. We never ask for a password or account, because there isn't one.

What a Valid ICCID Looks Like

A PikaSim ICCID is a 19 to 20 digit number, often beginning with 89 (the international prefix for telecom SIM cards). For example: 8985... or 8901.... If the value you're holding has letters in it, or is much shorter or longer, it is probably the wrong field, double-check it is the ICCID line and not the EID, IMEI, or activation code.

FAQ

What is an ICCID?

The ICCID (Integrated Circuit Card Identifier) is the unique serial number of your eSIM, usually 19 to 20 digits. PikaSim uses it to look up your eSIM, check usage, and apply top-ups. It is not your phone number.

Is the ICCID the same as the EID?

No. The EID is a 32-digit hardware ID for your phone's eSIM chip and stays the same no matter which eSIM is installed. The ICCID identifies one specific eSIM profile. On iPhone, the EID is at the top of Settings > General > About; the ICCID is lower down under a cellular line. Use the ICCID.

I see an IMSI in the SIM Applications menu. Can I use that?

The number in the SIM Applications (STK) menu is usually a longer, mangled value, not a clean identifier, so it will not match. Use the ICCID from Settings > General > About. (Support can also look you up by your clean 15-digit IMSI, also in Settings > General > About, if that is all you have.)

The ICCID isn't showing on my iPhone. Why?

The line is probably switched off. Go to Settings > Cellular, tap the eSIM line, and enable "Turn On This Line." The ICCID will then appear in Settings > General > About. The line does not need to be your data or voice line, just enabled.

What if I don't have the device or the purchase page?

Use the live chat at pikasim.com/help and tell us what you bought, roughly when, and how you paid. Because PikaSim is account-free, we verify ownership from those details and can match your order, no email or password needed.
