Number format in Argentina
Argentine mobiles in international format need a 9 after +54, then the area code without its 0 and the subscriber number without the local 15: a number dialled at home as 011 15-2345-6789 is sent as +54 9 11 2345 6789.
Alphabet and segments
Texts in Spanish fit 160 GSM-7 characters per segment until they use á, í, ó 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
Argentina keeps UTC-3 all year with no clock change, so 09:00 in Buenos Aires is always 12:00 UTC. send_at takes UTC or any ISO 8601 offset, and the console scheduler converts from your own time zone.
Send to Argentina with one request
The answer comes back at once with the message id, the country the number was matched to (AR) 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.
