Keep On Roaming eSIM Data Plans for Martinique

Keep On Roaming does not provide any truly unlimited high‑speed data plans for Martinique. The plans listed as “Unlimited” in the catalog each come with a 1GB data cap (either total or per day) and do not allow unlimited use of 4G/5G data. After the 1GB limit is reached, the speed is reduced, though the reduced speed is not specified in the data.

For travelers who need more than 1GB of high‑speed data, Keep On Roaming offers fixed‑data eSIMs such as the 20 GB 30 days plan priced at $89.00 USD and the 10 GB 30 days plan at $50.00 USD. These plans provide a larger data allowance and can be more cost‑effective for moderate to heavy users of mobile data.

Keep On Roaming does not offer a Martinique eSIM with a phone number or SMS capability. The provider only supplies data‑only eSIM plans for Martinique, so callers and text messages cannot be sent through the eSIM. Travelers who need communication can use popular VoIP apps such as WhatsApp, Telegram, or iMessage over the data connection to make calls and send messages.

Keep On Roaming lists 12 single-country data plans that cover Martinique and 12 multi-country plans that include Martinique among several destinations. The available plans vary in price from roughly $13 to $188, with data caps ranging from 1 GB up to 20 GB for up to 30 days of validity. Some offerings are “fixed data cap” plans, delivering a set amount of data that stays usable for the entire validity period, while others are “daily data cap” plans that allocate a specific amount of data that can be consumed each day. Both types occasionally allow tethering on compatible devices.
