Compatibility and coverage

It’s very simple! To use our eSIM, your phone only needs to meet two requirements: be eSIM-compatible and be unlocked to work with any carrier. Here’s how to check both:

First Requirement: eSIM-Compatible Phone

Most phones manufactured from 2019 onward include eSIM technology.

Some popular devices that are compatible:

• Apple: iPhone XR, XS and later (including all iPhone 11, 12, 13, 14, 15 and 16 models).
• Samsung: Galaxy S20, Note 20, Fold, Flip and later.
• Google: Pixel 3 and later.

Verify if your device is compatible here: all eSIM compatible phones.

Second Requirement: Unlocked Phone

“Unlocked” means your phone isn’t tied by contract to a single carrier (e.g., Telcel, AT&T, Movistar) and can use SIMs or eSIMs from other providers.

Quick check:

• On iPhone: Go to Settings > General > About. Scroll to “Carrier Lock”. If it says “No SIM restrictions”, it’s unlocked! If it says something else, it probably has a restriction.
• On Android: The surest way is to insert a friend’s SIM from a different carrier, if your phone recognizes it and shows signal, it’s unlocked. You can also call your carrier and ask.

For more details, see our complete guide on how to check if your phone is carrier unlocked.

Once you’ve confirmed both, you’re ready! You can purchase and install your Fulldatos eSIM package from anywhere in the world.

Yes, of course! Our eSIM gives you a second line solely for mobile data, while your primary line and WhatsApp remain unchanged. Just make sure to turn off your primary line to avoid any charges from your carrier abroad.

Our eSIMs are designed for mobile data only, so they don’t include a phone number for traditional calls. However, you can make voice or video calls using internet-based apps, consuming data from your eSIM package.

Option 1: App-based calls (recommended)

Use WhatsApp, FaceTime, Zoom, Telegram, Facebook Messenger, etc.

Option 2: Traditional calls

For calls to landlines or mobile numbers, you must use your primary line (physical SIM or primary eSIM).

Important: Your primary line must be turned on and may incur roaming charges. Check fees with your carrier before placing a call.

Our eSIMs are designed to connect to local networks, so they won’t have coverage while you’re sailing in open water. However, they will work perfectly and automatically reconnect as soon as your cruise ship approaches the coast or docks in any of the countries included in your eSIM package.
