Simsima eSIM Data Plans for Caribbean

Simsima does not provide a true unlimited data eSIM for the Caribbean. The only plan listed with “Unlimited” in the name is the Unlimited – 7 days option, which actually allows 3 GB per day and then throttles speeds to 1000 kbps. For travelers who need more data without the speed reduction, Simsima offers several fixed‑data plans, such as the 20 GB – 30 days bundle and the 10 GB – 30 days options, which provide high‑speed data for the full validity period. Choosing a fixed‑data plan can be a more cost‑effective solution unless a user requires very high data consumption.

Simsima does not provide eSIM plans for Caribbean destinations that include a local phone number or SMS capability. Travelers who need a per‑minute voice connection or standard text messaging will not find these services available from this provider, and only data‑only plans are sold.

For voice and messaging, users can rely on VoIP applications such as WhatsApp, Telegram, or iMessage when connected to the data plan. However, some Caribbean destinations may restrict or block certain apps, so it is advisable to check that the services you rely on are accessible before purchasing a data‑only eSIM from Simsima.

The unnamed plan offered by Simsima covers the following Caribbean countries: Antigua and Barbuda, Anguilla, Aruba, Barbados, Saint Barthélemy, Bonaire, Sint Eustatius, Saba, Bahamas, Curaçao, Dominica, Dominican Republic, Grenada, Guadeloupe, Haiti, Jamaica, Saint Kitts and Nevis, Cayman Islands, Saint Lucia, Saint Martin, Martinique, Montserrat, Puerto Rico, Sint Maarten, Turks and Caicos Islands, Trinidad and Tobago, Saint Vincent and the Grenadines, and the British Virgin Islands.
