Number format in Tonga
Mobile numbers in Tonga have 7 digits after +676 and no trunk prefix, so the local form 771 5123 becomes +676 771 5123 in the to field.
Alphabet and segments
English and Pacific languages text stays inside the GSM-7 alphabet, so one segment to Tonga 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
Tonga keeps UTC+13 all year with no clock change, so 09:00 in Tongatapu is always 20:00 UTC. send_at takes UTC or any ISO 8601 offset, and the console scheduler converts from your own time zone.
Send to Tonga with one request
The answer comes back at once with the message id, the country the number was matched to (TO) 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.
