How to choose the right plan
- Light use — maps, messaging and browsing — needs about 1 GB per day.
- Heavy use — social video, streaming or hotspotting a laptop — plan for 2-3 GB per day or pick the largest plan.
- Match the validity to your trip length, with a day or two of buffer for delays.
How activation works
- Buy the plan and receive your eSIM by email within minutes.
- Install it from your phone settings while still at home — no store visit, no plastic SIM.
- Land in Cayman Islands, enable the eSIM line, and you are online before leaving the airport.

Install it before you fly. Grand Cayman 4G covers WhatsApp to the operator and grocery maps. Download offline maps if you fly to the Sister Islands — coverage is thinner and the last shop closes earlier than you think.
