BetterRoaming does not sell eSIM plans for Trinidad and Tobago that include a phone number or SMS capability. The only available options from this provider for that destination are data‑only plans.
Travelers can still use VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection to make calls and send messages, but some destinations may block or restrict access to specific apps or VoIP services. It is advisable to confirm that the messaging and calling apps you rely on work in Trinidad and Tobago before purchasing a data‑only plan.
