Frequently Asked Questions

Find answers to common questions about our eSIM services

An eSIM (embedded SIM) is a digital SIM card that allows you to connect to mobile networks without needing a physical SIM card. It's a tiny chip built directly into your device that can be programmed remotely to connect to different carriers. Unlike traditional plastic SIM cards that you insert into your phone, an eSIM is permanently embedded in your device and can be activated instantly through a simple QR code scan or app download.

eSIM technology works by storing your carrier profile digitally on a secure chip inside your device. When you purchase an eSIM plan, you receive a QR code or activation code. Scanning this code downloads your carrier profile to the eSIM chip, which then authenticates with the mobile network just like a traditional SIM card. The profile contains your phone number, network settings, and authentication credentials. The entire process is managed through software, making it instant and convenient.

• Instant Activation: No waiting for physical delivery, activate in seconds
• Multi-Profile Support: Store multiple carrier profiles on one device
• Perfect for Travel: Switch between local carriers without changing SIM cards
• Environmentally Friendly: Eliminates plastic waste from SIM cards
• No Lost SIM Cards: Everything is digital and secure
• Dual SIM Capability: Use your home number and travel number simultaneously
• Space Saving: Allows device manufacturers to make phones thinner and add more features
• Remote Management: Easily switch carriers or plans without visiting a store

Yes! Most modern smartphones support dual SIM functionality, allowing you to use both an eSIM and a physical SIM card simultaneously. This is perfect for travelers who want to keep their home number active while using a local data plan. For example, you can keep your primary number on your physical SIM for calls and texts, while using an eSIM for affordable local data in the country you're visiting. Some newer devices like iPhone 13 and later even support dual eSIM functionality without needing a physical SIM at all.

Yes, eSIM is highly secure. The eSIM chip uses the same security standards as physical SIM cards, including encryption and authentication protocols. Because it's embedded in your device, it can't be physically removed or stolen like a traditional SIM card. All eSIM profiles are digitally signed and encrypted, making them extremely difficult to hack or clone. The remote provisioning process also uses secure channels to protect your data during activation.

Physical SIM: Removable plastic card, requires physical delivery, can be lost or damaged, one profile per card, manual installation required, takes up device space.

eSIM: Digital/embedded chip, instant activation via QR code, cannot be lost, can store multiple profiles, software-based installation, saves device space, more environmentally friendly, easier to switch carriers.

Functionally, both provide the same mobile connectivity - the main differences are in convenience, flexibility, and how they're managed.

Most devices can store between 5-10 eSIM profiles, though you can only have 1-2 active at the same time depending on your device. For example:
• iPhone XS to iPhone 12: Can store 8 eSIMs, use 1 at a time with 1 physical SIM
• iPhone 13 and newer: Can store 8+ eSIMs, use 2 eSIMs simultaneously (no physical SIM in US models)
• Samsung Galaxy S20+: Can store 5 eSIMs, use 1 eSIM + 1 physical SIM
• Google Pixel 4+: Can store multiple eSIMs, use 1 eSIM + 1 physical SIM

This means you can keep profiles for different countries or carriers stored and easily switch between them as needed.

The industry is moving toward eSIM-only devices. Apple already released iPhone 14 models in the US without a physical SIM card slot, using only eSIM technology. Major carriers worldwide are increasingly supporting eSIM, and it's expected that most new devices will be eSIM-only within the next few years. However, physical SIM cards will likely remain available for some time to support older devices and regions where eSIM infrastructure is still developing.

To check if your device supports eSIM, go to Settings and look for "Add Cellular Plan" or "Add eSIM" option, or dial *#06# to see if an EID number appears.

No, each eSIM profile can only be installed and activated on ONE device at a time. This is a security feature to prevent unauthorized use. Once you scan the QR code and install the eSIM, the profile is bound to that specific device.

If you try to scan the same QR code on another device, it will typically fail or deactivate the eSIM on the first device. If you need connectivity on multiple devices (phone, tablet, watch), you'll need to purchase separate eSIM plans for each device.

⚠️ Important: Be careful when removing or deleting an eSIM profile, as some carriers don't allow reinstallation of the same QR code. Always contact support before removing an eSIM if you might need to reinstall it.

eSIM activation is typically INSTANT! Here's the timeline:

• Purchase to Email: 1-2 minutes (you receive QR code immediately)
• QR Code Scan: 10-30 seconds
• Profile Download: 30 seconds - 2 minutes (depends on WiFi speed)
• Network Registration: Instant to 5 minutes
• Full Activation: Usually complete within 5 minutes total

In rare cases, activation might take up to 15-30 minutes, especially if:
- Your device needs to restart
- Network coverage is poor
- The carrier needs to provision your profile
- There's high network traffic

💡 Tip: For travel eSIMs, we recommend activating your eSIM while still at home on WiFi, but only turn on data roaming when you arrive at your destination to start your plan validity period.

Yes, a stable WiFi connection is REQUIRED for the initial eSIM installation and profile download. This is because:

1. The eSIM profile needs to be downloaded from the carrier's server (typically 1-5 MB)
2. Your device needs to authenticate and register with the network
3. Configuration files need to be securely transferred

After installation is complete, you can disconnect from WiFi and use your eSIM's mobile data connection.

⚠️ Make sure your WiFi is stable during installation - if the connection drops during download, you may need to restart the process.

Yes! We actually RECOMMEND installing your travel eSIM before your trip:

✅ Install at home on stable WiFi: Download and install the eSIM profile while you're still at home
✅ Keep it inactive: Don't turn on "Data Roaming" or set it as your primary line
✅ Test before departure: Verify the profile is installed correctly
✅ Activate at destination: Turn on data roaming when you land

Benefits:
• No stress at the airport looking for WiFi
• Instant connectivity upon arrival
• Time to troubleshoot any issues before traveling
• Can contact support easily if needed

📝 Note: For most plans, validity starts when you first connect to the network (turn on data roaming), not when you install the profile. Check your specific plan details for activation policy.
