Does Yesim offer unlimited data eSIM for Cayman Islands?
Yesim offers unlimited data eSIM plans for the Cayman Islands, available in validity periods of 1, 7, 15, and 30 days. Prices range from $17.81 for a 1‑day plan up to $117.57 for a 30‑day plan, and some of these unlimited options are advertised on 5G networks. The plans state that speed may be throttled, which is common when a Fair Usage Policy is applied after heavy use.
Because the unlimited plans may include a Fair Usage Policy, speeds can be reduced after consuming large amounts of data. If a traveler is concerned about potential speed restrictions, it is advisable to contact Yesim directly to confirm whether FUP applies and to inquire about the typical data volume that can be used at normal speeds.
Does Yesim offer Cayman Islands eSIM with phone number and SMS?
Yesim does not provide eSIM plans for the Cayman Islands that include a phone number or SMS capability. All available Cayman Islands eSIMs from Yesim are data‑only. Travelers who need voice or text communication can use popular VoIP apps such as WhatsApp, Telegram, and iMessage, which work over the data connection and do not require a local phone number or SMS service.
How many data plans does Yesim offer for Cayman Islands?
Yesim provides 7 single‑country data plans and 10 multi‑country data plans for travelers to the Cayman Islands. The plans cover a price range of roughly $17.81 to $129.44 USD and offer data caps from 3 GB up to unlimited usage. Some plans include tethering, though speed may be throttled.
