Common Questions

The details worth knowing about your Cayman Islands eSIM

No. Little Cayman has limited mobile coverage compared to Grand Cayman and Cayman Brac. If you travel there, you may experience weaker signal or no service in some areas, even with a working eSIM.

The eSIM connects to either Flow or Digicel, the two mobile operators in the Cayman Islands. Flow offers 4G on bands B3 and B5 and 5G on band n78. Digicel offers 4G on bands B3 and B5 but no 5G.

No. Flow's 5G network uses only band n78, concentrated in George Town and Seven Mile Beach. If your phone does not support n78, you will only get 4G or lower speeds on Flow, and no 5G on Digicel, which has no 5G.

No. This eSIM is for the Cayman Islands only. It does not include coverage in Cuba, Jamaica, or any other neighbouring country. If you plan to visit multiple destinations, you will need a separate eSIM for each.

No. eSIMs for the Cayman Islands do not require local ID or passport registration. You can install and activate the eSIM remotely before or after arrival, with no need to visit a store or provide personal documents to a local operator.
