Number format in Hong Kong
Mobile numbers in Hong Kong have 8 digits after +852 and no trunk prefix, so the local form 5123 4567 becomes +852 5123 4567 in the to field.
Alphabet and segments
Text in traditional Chinese characters is always Unicode, so a message to Hong Kong written in Cantonese Chinese carries 70 characters in one segment and 67 in each part of a longer one. Codes and alerts written in English or plain Latin letters fit 160 characters, which halves the cost of a long notice.
Time zone and timing
Hong Kong keeps UTC+8 all year with no clock change, so 09:00 in Hong Kong is always 01:00 UTC. send_at takes UTC or any ISO 8601 offset, and the console scheduler converts from your own time zone.
Send to Hong Kong with one request
The answer comes back at once with the message id, the country the number was matched to (HK) 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.
