Yesim eSIM Data Plans for Saint Martin

Yesim offers unlimited data eSIM plans that cover Saint Martin. The local Yesim plan provides Unlimited data for 1 day at $51.88 USD, while a Caribbean plan that includes Saint Martin +14 countries offers Unlimited data for 1 day at $21.23 USD. Both plans allow tethering and specify that speeds may be throttled after heavy usage.

Because the unlimited plans come with a Fair Usage Policy, speeds may be reduced once a high‑usage threshold is reached. If you need confirmation on whether speeds will stay at normal 5G (for the Caribbean plan) or how much data can be used before throttling, contact Yesim directly for the most accurate information.

Yesim does not provide eSIM plans for Saint Martin that include a phone number or SMS capability. Only data‑only eSIMs are available from Yesim in Saint Martin, and travelers can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection for voice calls and messaging.

The plans range in price from roughly $20.76 to $76.13 and offer data limits from 1 GB up to unlimited.
