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.

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