Number format in Trinidad and Tobago
Trinidad and Tobago uses the North American Numbering Plan: +1, a three-digit area code and a seven-digit number, such as +1 868 291 1234. The API reads the area code (868 here) to price the number as Trinidad and Tobago rather than the United States, so keep the full eleven digits in your list.
Alphabet and segments
English text stays inside the GSM-7 alphabet, so one segment to Trinidad and Tobago holds 160 characters and each part of a longer text 153. Watch for curly quotes and emoji copied from other tools: one of them moves the whole text to Unicode at 70 characters per segment, and POST /v1/estimates shows the encoding before you send.
Time zone and timing
Trinidad and Tobago keeps UTC-4 all year with no clock change, so 09:00 in Port of Spain is always 13:00 UTC. send_at takes UTC or any ISO 8601 offset, and the console scheduler converts from your own time zone.
Send to Trinidad and Tobago with one request
The answer comes back at once with the message id, the country the number was matched to (TT) and the price. A delivered or failed event follows on your webhook, and a failed message is refunded.
For a list, send the same text to up to 10,000 numbers with POST /v1/batches, or a personal text per number in messages.
