Yesim eSIM Data Plans for Saint Lucia

Yesim provides several unlimited eSIM options for travellers heading to Saint Lucia. The unlimited plans available run from a 1‑day plan at $20.09 USD to a 15‑day plan at $93.34 USD, with a 7‑day Global Plus version priced at $76.80 USD and a 15‑day version at $116.97 USD. All of these plans note that speed may be throttled, meaning that while data is unlimited, high‑speed access could be reduced after heavy usage under a fair‑use policy. Some packages, such as the Caribbean and Global Plus, specify 5G network coverage, whereas others do not list a specific network. Travelers who need confirmation about potential speed restrictions and typical data allowances at normal speed should contact Yesim directly.

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 offers six single‑country plans that provide data only while you stay in Saint Lucia. In addition, ten multi‑country plans include Saint Lucia as one of several destinations, allowing simultaneous data use across a broader region. Plan prices range from $20.09 up to $128.78, while data caps span from as little as 3 GB to Unlimited; some plans allow tethering, though speeds may be throttled.
