Frequently Asked Questions
Does Firsty offer unlimited data eSIM for Cayman Islands?
Firsty does not offer an unlimited data eSIM plan for the Cayman Islands. All available options give a fixed data allowance, such as the Firsty First Class plan that supplies 5 GB for a day, or the 5 GB per day options that last 3, 5, 7, or 10 days. These fixed‑data plans are the only types currently offered. Choosing a fixed data plan can be more cost‑effective for most travelers, unless a user needs an extremely heavy data budget that would require many days of coverage.
Does Firsty offer Cayman Islands eSIM with phone number and SMS?
Firsty does not offer Cayman Islands eSIM plans that include a phone number or SMS capability. The available plans are data‑only, so travelers will need to rely on data for voice and messaging. Popular VoIP applications such as WhatsApp, Telegram, and iMessage work over the data connection and allow calls and messaging without a local phone number.
How many data plans does Firsty offer for Cayman Islands?
Firsty currently offers 16 single‑country data plans for the Cayman Islands, with no multi‑country options available. Of these, 14 plans feature a daily data cap—meaning the allotted data is refreshed each day—while 2 plans provide a fixed data amount that can be used over the entire validity period. Prices for the Cayman Islands plans range from roughly $14.37 to $718.63, and the data caps offered span from 1.5 GB to 5 GB.
