How does our Cayman Islands eSIM work?

An eSIM is an embedded SIM card, and you probably already have an eSIM-compatible device. When you install an eSIM for a country or region, it lets your device connect to local networks in that area. This means your device will have data without needing Wi-Fi or paying roaming charges.

Use a Cayman Islands eSIM for instant travel data

Whether you visit Grand Cayman, Cayman Brac, or Little Cayman, the Cayman Islands exude happiness, relaxation, and an adventurous spirit you’ll never forget.

During your time in the Cayman Islands, you’ll probably want mobile data so you can check driving directions, make reservations, and chat with friends and family back home. A Cayman Islands eSIM connects your device to a local network, giving you affordable prepaid mobile data.


How much travel data do I need with my Cayman Islands eSIM?

How much data you’ll need in the Cayman Islands will depend on how often you will want an internet connection but won’t have access to Wi-Fi. This can really differ depending on your average data usage, and your location.

Not sure? You can pick a smaller Cayman Islands data package and then top up later if you need more during your travels in the Cayman Islands.

We also have a travel data calculator to help you estimate how much data you’ll need for your trip, based on predicted usage.


Will I pay roaming charges with a prepaid eSIM for Cayman Islands?

You won’t pay a penny in roaming charges when you’re using a Cayman Islands eSIM for your mobile data.

Just install your Cayman Islands eSIM while you have a strong internet connection (either at home, or while already travelling), and then activate your prepaid Cayman Islands data package when you’re ready to use it.

To avoid roaming charges on your primary SIM, please make sure you’ve turned off Data Roaming on your primary SIM (and confirmed you aren’t enrolled in a carrier travel plan) to prevent your home carrier from adding roaming charges to your next bill.

FAQs about using a Cayman Islands eSIM

Check my device

Most newer phones, tablets, and computers are already eSIM-compatible, so use our eSIM device checker to make sure you have a device that can accept an eSIM.

Free Wi-Fi is great when it’s available, safe, and working well, but some destinations make it just about impossible to get a good connection. That’s why it’s nice to have data as a backup to stay connected.

We’re proud to provide aloSIM customers with fast eSIM data connections that allow them to talk, text, surf, and stream comfortably. You’ll likely experience a 4G (sometimes 5G) or LTE equivalent network in most locations, depending on what’s available in the area.

Installation guides

We have detailed eSIM installation instructions for all compatible devices, so whether you’re looking to add eSIM data to an iPhone or iPad, Google Pixel, Samsung Galaxy, or something else, we’ll be able to walk you through the eSIM set-up process easily.

How to avoid roaming charges

It can be confusing to know the best roaming settings for your phone while you travel internationally, so we’ve created an easy walk-through guide to show you exactly how your phone’s roaming settings should look.
