What Is an ICCID?
The ICCID (Integrated Circuit Card Identifier) is the unique digital fingerprint that identifies your SIM card or eSIM profile. Think of it as your SIM's passport—a globally unique 19-20 digit code that distinguishes your connection from billions of others worldwide.
Breaking Down the ICCID Structure

Every ICCID tells a story through its digits. Let's decode what these numbers mean:
First Two Digits (89): These digits identify telecommunications as the industry. They're consistent across all SIM cards globally, serving as a universal marker that you're looking at a mobile network identifier.
Country Code (Next 1-3 digits): This section indicates the country or region where the SIM was issued. For example, "1" represents North America, while "44" represents the United Kingdom. Some providers, including international eSIM services, may use special non-terrestrial country codes that enable global roaming capabilities.
Issuer Identifier (Next 1-4 digits): These digits identify the specific mobile network operator or MVNO (Mobile Virtual Network Operator) that issued your SIM.
Individual Account Number (Next 12 digits): This is where your SIM becomes truly unique. These digits, combined with the previous identifiers, ensure that no two SIM cards in the world share the same ICCID.
Check Digit (Final digit): The last digit serves as a verification tool, helping systems validate that the ICCID has been entered correctly.
Why Your ICCID Matters for Modern Travel
Understanding your ICCID isn't just technical knowledge—it's practical wisdom that can transform your travel experience. Here's why this number matters more than you might think:
Seamless Customer Support
When you need assistance with your mobile connection abroad, your ICCID is the golden key. It allows support teams to instantly locate your specific eSIM profile, diagnose issues, and provide targeted solutions without lengthy verification processes. Whether you're troubleshooting connectivity in a Tokyo subway station or need to top up data while exploring the streets of Barcelona, having your ICCID ready means faster resolution and less stress.
Effortless Plan Management
Modern travelers often juggle multiple data plans across different destinations. Your ICCID enables precise tracking of which plan is active, how much data remains, and when it's time to recharge. This granular visibility helps you avoid unexpected service interruptions and manage your connectivity budget more effectively.
Top-Up and Reactivation Made Simple
Here's a pro traveler tip: don't delete your eSIM after your trip ends. By keeping your eSIM profile on your device, you can reuse the same ICCID to reload with new data plans for your next adventure. This means no more scanning QR codes or going through lengthy installation processes—just a quick reload to your existing ICCID, and you're ready to roam again. Whether you're returning to the same country or exploring somewhere completely new, your Travelgator ICCID works universally across all our supported destinations.
How to Find Your ICCID: A Step-by-Step Guide
Knowing where to find your ICCID can save you valuable time when you need it most. Here's how to locate it on different devices:

eSIM vs. Traditional SIM: Understanding the Evolution
The transition from physical SIM cards to eSIMs represents one of the most significant shifts in mobile connectivity. Understanding the difference helps you appreciate why eSIM technology, powered by ICCIDs, offers such superior flexibility for travelers.
The Physical SIM Era
Traditional SIM cards require physical installation, which means hunting for tiny ejector tools, carefully removing cards without losing them, and hoping you don't damage the delicate chip. For travelers, this often meant purchasing local SIMs at airports, fumbling with unfamiliar packaging, and keeping track of multiple physical cards.
The eSIM Revolution
eSIMs eliminate these friction points entirely. The "e" stands for "embedded"—the SIM is built directly into your device's hardware. What changes is the digital profile loaded onto that chip, identified by its unique ICCID. This means you can switch between carriers, add new plans, or activate travel data without ever touching a physical card.
For the modern traveler, this translates to purchasing connectivity from your hotel room, activating service mid-flight, or adding a backup plan from a beach in Bali—all through digital delivery and instant activation.
Understanding EID: The eSIM's Hardware Identity
While ICCID identifies your eSIM profile, the EID (eSIM Identifier) represents the physical eSIM chip in your device. Think of it this way:
- EID: The hardware serial number—it's permanently embedded in your device and never changes
- ICCID: The profile identifier—it changes with each new eSIM plan you install
This distinction matters because the EID enables your device to hold multiple eSIM profiles simultaneously. Most modern smartphones can store 5-10 different eSIM profiles, though you can typically only have 1-2 active at once. This flexibility is perfect for travelers who want to maintain their home line while adding local data plans in different countries.
ICCID vs. IMSI vs. IMEI: Demystifying Mobile Identifiers
The mobile connectivity world speaks in acronyms. Here's what you need to know:
ICCID (Integrated Circuit Card Identifier): Identifies your specific SIM card or eSIM profile. This is what you'll reference when managing your Travelgator eSIM or seeking support.
IMSI (International Mobile Subscriber Identity): Identifies your subscription on the network. While related to your ICCID, the IMSI is used by networks to authenticate and route your connection. Most travelers never need to interact with their IMSI directly.
IMEI (International Mobile Equipment Identity): Identifies your physical device—your smartphone or tablet. This number is unique to your hardware and remains constant regardless of which SIM or eSIM you're using. The IMEI is primarily used for device tracking, warranty validation, and network blacklisting of stolen phones.
All three work together to create your mobile identity, but for day-to-day travel connectivity management, your ICCID is the number that matters most.

Multi-SIM Functionality: Maximizing Your Connectivity
Modern smartphones support dual-SIM functionality, allowing you to maintain two active lines simultaneously. This capability has revolutionized how savvy travelers manage their connectivity:
The Home + Travel Configuration
Keep your primary SIM active for important calls and messages while running a Travelgator eSIM for affordable data abroad. This eliminates the anxiety of missing important communications while avoiding punishing roaming charges from your home carrier.
The Backup Strategy
Install eSIMs from multiple providers before your trip. If one network performs poorly in your destination, you can quickly switch to your backup without scrambling to find local connectivity solutions.
The Regional Approach
For travelers covering multiple countries, you can install destination-specific eSIMs in advance and activate them as you cross borders. This ensures optimal local network performance in each region you visit.
Checking eSIM Compatibility: Is Your Device Ready?
Not all devices support eSIM technology. Before committing to an eSIM travel plan, verify that your smartphone or tablet is eSIM-capable. Generally, devices released after 2018 from major manufacturers include eSIM support:
Apple Devices: iPhone XS, XR, and newer models; iPad Pro 11-inch and 12.9-inch (3rd generation and later); iPad Air (3rd generation and later); iPad (7th generation and later); iPad mini (5th generation and later)
Android Devices: Google Pixel 3 and newer; Samsung Galaxy S20 and newer (certain models); Samsung Galaxy Z Flip and Fold series; select Motorola, Oppo, and Huawei models
Check Your Settings: The quickest way to verify eSIM support is to look for eSIM or cellular plan options in your device settings. If you can add a cellular plan digitally, your device supports eSIM technology.
