Number format in United Kingdom
Mobile numbers in the United Kingdom have 10 digits after +44. Locally they are written with a leading 0 (07400 123456); in the API that 0 is dropped, so the same number goes in the to field as +44 7400 123456. Jersey, Guernsey and the Isle of Man share +44 and are priced by their own mobile prefixes.
Alphabet and segments
English text stays inside the GSM-7 alphabet, so one segment to the United Kingdom 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
The United Kingdom changes its clocks: London is on UTC+0 in January and UTC+1 in July. 09:00 in London is 09:00 UTC in January and an hour earlier in UTC while summer time runs, so give send_at with the local offset (for example +00:00 in winter) and the API does the conversion.
Send to United Kingdom with one request
The answer comes back at once with the message id, the country the number was matched to (GB) 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.
