Yesim eSIM Data Plans for Saint Lucia

Yesim offers unlimited eSIM plans for Saint Lucia. The provider sells a 1‑day unlimited plan for $19.83 USD, a 7‑day unlimited plan for $57.17 USD, and a 15‑day unlimited plan for $92.16 USD. Each plan allows tethering and is delivered over 3G or LTE networks.

Because the data allowance is unlimited, the speeds may be throttled after heavy use under a Fair Usage Policy. If a traveler is concerned about potential speed reductions, they should contact Yesim directly to confirm whether the FUP applies and the typical amount of data that can be used at normal speed.

Yesim does not provide an eSIM for Saint Lucia that includes a phone number or SMS capability. The provider only offers data‑only eSIM plans for this destination.

Travelers can still use VoIP services such as WhatsApp, Telegram, or iMessage over the data connection to make calls and send messages without a local phone number.

Yesim provides a selection of plans that cater specifically to travelers visiting Saint Lucia. The provider lists six single‑country data plans that cover only Saint Lucia, while also offering ten multi‑country plans that include Saint Lucia as part of a broader roaming network. The available plans vary in price from roughly $19.83 up to $127.16 per data package, and in data capacity from as little as 3 GB to unlimited options. Some plans are a fixed data amount for the entire validity period, whereas others impose a daily data cap that can be rolled over if unused. This range gives travelers flexibility to choose a plan that matches both their budget and data needs.
