Number format in Guinea-Bissau
Mobile numbers in Guinea-Bissau have 9 digits after +245 and no trunk prefix, so the local form 955 012 345 becomes +245 955 012 345 in the to field.
Alphabet and segments
Texts in Portuguese fit 160 GSM-7 characters per segment until they use á, â, ã, ç, ê, í, ó, ô, õ and ú: those letters are outside GSM-7 and turn the message into Unicode at 70 characters per segment (67 per part). For short alerts, write them without those letters to keep one segment; for longer texts, the console names each letter that changed the encoding.
Time zone and timing
Guinea-Bissau keeps UTC+0 all year with no clock change, so 09:00 in Bissau is always 09:00 UTC. send_at takes UTC or any ISO 8601 offset, and the console scheduler converts from your own time zone.
Send to Guinea-Bissau with one request
The answer comes back at once with the message id, the country the number was matched to (GW) 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.
