What is an eSIM ICCID?

The ICCID (Integrated Circuit Card Identifier) is the unique 19-20 digit serial number of your eSIM profile, filling the same role a physical SIM card number plays. It identifies your specific eSIM for top-ups, support and recovery.

Where do I find my eSIM's ICCID on iPhone?

Settings > General > About, then scroll to the SIM/eSIM section. Your eSIM's ICCID appears under its plan label. Long-press the number to copy it. If you have multiple SIMs, each line lists its own ICCID.

Where do I find the ICCID on Android?

Settings > About phone > SIM status (path varies by brand: on Samsung it is Settings > About phone > Status > SIM card status). You can also dial *#06# on many phones to display ICCIDs alongside IMEIs.

Can I top up an eSIM without an account?

Yes. With nadanada, the ICCID (or your order details from the confirmation page) is all you need. There is no login because there is no account. Enter the ICCID on the top-up page, pay, and the data is added to your existing eSIM without reinstalling anything.

Treat it like a serial number: it identifies your SIM but reveals nothing about you by itself. Share it with your provider's support when troubleshooting, but there is no reason to post it publicly.

What is the difference between ICCID, IMEI, EID and IMSI?

ICCID identifies your SIM profile (the plan). IMEI identifies your phone hardware. EID identifies your phone's eSIM chip. IMSI identifies your subscription on the network. For top-ups and eSIM support, the ICCID is the one you need.

How to Find Your eSIM's ICCID (and Top Up Any eSIM)

Every eSIM has a unique serial number called the ICCID, and with nadanada it is the key to topping up your data or getting support without ever having an account. This guide explains what it is and where to find it on iPhone and Android.

What the ICCID is

ICCID stands for Integrated Circuit Card Identifier: a 19-20 digit number that uniquely identifies your eSIM profile, exactly like the number printed on a physical SIM card. It typically starts with 89 followed by a country code.

Because nadanada has no accounts (no email, no password, no login), the ICCID is how you reference your eSIM later: topping up, checking status, or getting support. Save it, screenshot your confirmation page, or bookmark it.

Find your ICCID on iPhone

Settings > General > About
Scroll to the SIM / eSIM section (you will see one entry per line if you use dual SIM)
Find the line labeled with your travel eSIM's name
Long-press the ICCID to copy it

Find your ICCID on Android

Paths vary slightly by brand:

Stock/Pixel: Settings > About phone > SIM status
Samsung: Settings > About phone > Status > SIM card status
Universal shortcut: dial *#06#, which on many phones lists ICCIDs together with IMEI and EID numbers

Top up without an account

Topping up a nadanada eSIM takes under a minute:

Click "My Services" or the yellow icon in the right upper section.
Enter your ICCID (or use the link on your saved confirmation page)
Pick a data package and pay with crypto or card
Data lands on your existing eSIM within moments. No QR code, no reinstall, no interruption

This is why buying "a bit short" and topping up beats overbuying: start with the plan that covers your expected use and extend only if you actually run low.

ICCID vs. the other identifiers

Code	Identifies	When you need it
ICCID	Your eSIM profile/plan	Top-ups, support, recovery
IMEI	Your phone hardware	Carrier unlocks, theft reports
EID	Your phone's eSIM chip	Some manual eSIM activations
IMSI	Your subscription on the network	You never need it directly

Lost your ICCID and your confirmation page?

Your phone still knows it. Use the steps above to pull the ICCID from Settings while the eSIM is installed. That number plus your payment reference is enough for nadanada support to locate your plan and help.
