Cayman Islands eSIM — FAQ
How do I get an eSIM for Cayman Islands?

Will my phone work with a Cayman Islands eSIM?
Most phones from the last few years support eSIM, including iPhone XS and newer, Google Pixel 3+, and recent Samsung Galaxy S/Z models. Your phone must be carrier-unlocked.
Does the Cayman Islands eSIM include 5G?
Yes — our Cayman Islands plans connect to 5G where the local network supports it, and fall back to 4G/LTE automatically.
Can I keep my own phone number?
Yes. The eSIM runs as a separate data line, so you keep your main number for calls and texts while using Cayman Islands data on the eSIM.
When does my plan start?
Your validity begins when the eSIM first connects to a network in Cayman Islands, so you can install it before you travel and it won't start counting down until you arrive.
