ByteSIM eSIM Data Plans for Saint Lucia

ByteSIM does not provide an unlimited data eSIM plan for Saint Lucia. All of ByteSIM’s available plans for the island offer a capped data allowance, the largest of which is a 10 GB data package.
Customers who need more data can choose from the fixed‑data options. For example, ByteSIM offers a 10 GB plan that is valid for 3 days, 5 days, 7 days, 10 days or 15 days, each allowing tethering. Selecting a fixed‑data plan can be more cost‑effective for travelers who are not heavy data users, while those who require large amounts of data should compare the best available data allowances across providers.

ByteSIM does not offer a Saint Lucia eSIM that includes a local phone number or SMS capability. The provider only supplies data‑only eSIM plans for Saint Lucia, so travelers cannot make or receive traditional voice calls or text messages. For voice and messaging, users can rely on internet‑based services such as WhatsApp, Telegram, or iMessage, which work over the data connection that the eSIM provides.

ByteSIM currently offers 34 single coverage data plans for Saint Lucia. These plans range in price from $4.90 to $119.00 and include data allowances from 500MB up to 10GB. Some plans offer a daily data cap, while others provide a fixed data allowance for the duration of the plan. There are currently no multi-country plans available from ByteSIM that include coverage for Saint Lucia.
