Before you land in Cayman Islands
Our Cayman Islands plan uses FLOW (5G), and the Caribbean pack covers Cayman too if your trip takes in other islands. If you come ashore from a cruise ship, the eSIM works on land and in port on the local network but never at sea, so turn off roaming on your home SIM before you sail.

Questions
What is the best eSIM for Cayman Islands?
For most trips, 5 GB for 30 days is enough: $33.90 here, against $36.00 at Airalo for the same data (read 5 Nov 2026). It is data only and needs no app: the QR code and a one-tap install link arrive by email. Every brand's price for Cayman Islands, dated and sourced, is on our comparison page.
Which Cayman Islands eSIM for a month?
Every one of these lasts 30 days: 3 GB $21.90, 5 GB $33.90, 10 GB $60.90. The 30 days start when the eSIM first connects to a network there, so you can buy before the trip.
Can I buy a Cayman Islands eSIM without an app?
Yes. You pay on this page and the QR code and a one-tap install link arrive by email: no app and no account. It is data only, with no phone number, so your home SIM keeps your calls and SMS.
Does the Cayman Islands eSIM come with a phone number?
No. It is data only: no local number, calls or SMS on this eSIM. Your home SIM stays in the phone for calls and texts (your carrier's roaming rates apply to them), and WhatsApp, FaceTime or Signal calls run over the eSIM's data. If you need a local number in Cayman Islands, for example for a service that texts a code, buy a local SIM there.
Which Cayman Islands eSIM for a week or two?
For 7 days: 1 GB $8.90. The 30-day packs cover one or two weeks too: 3 GB $21.90, 5 GB $33.90.
Will WhatsApp keep my number with a Cayman Islands eSIM?
Yes. WhatsApp stays on your home number: this eSIM is data only and has no number. Leave your home SIM in the phone with its data roaming off, use the Cayman Islands eSIM for mobile data, and do not re-register WhatsApp.
