Why get an eSIM for Cayman Islands?
An AeroCell eSIM for Cayman Islands gets you online the moment you land — no SIM swap, no roaming charges, no kiosk queue. Choose from 9 prepaid data plans from $13.49 with data options up to 20 GB and validity up to 30 days. It connects to FLOW 5G — the same coverage locals use.
Buy before you fly: install in one tap from the AeroCell app (iPhone and newer Androids) or with the QR code that arrives by email right after checkout — it takes about a minute — and the plan activates when the eSIM first connects to a network in Cayman Islands. Your regular SIM keeps working for calls and texts, so you stay reachable on your own number while the eSIM handles data.
