Number format in Guernsey

Mobile numbers in Guernsey have 10 digits after +44. Locally they are written with a leading 0 (07781 123456); in the API that 0 is dropped, so the same number goes in the to field as +44 7781 123456. Guernsey shares +44 with the United Kingdom; mobiles starting 7781, 7839 or 7911 price as Guernsey.

Alphabet and segments

English text stays inside the GSM-7 alphabet, so one segment to Guernsey 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

Guernsey changes its clocks: Guernsey is on UTC+0 in January and UTC+1 in July. 09:00 in Guernsey 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 Guernsey with one request

The answer comes back at once with the message id, the country the number was matched to (GG) and the price. A delivered or failed event follows on your webhook, and a failed message is refunded.
