SMS API for Mexico: bulk SMS to +52 numbers

Mexico, located in North America, has Mexico City as its capital and a diverse economy driven by manufacturing, tourism, and agriculture. Developers integrate SMS into systems like e-commerce platforms, banking apps, and travel agencies. Messages are triggered by events such as order confirmations, payment receipts, or flight updates. SMS is chosen because it reaches all phones, including basic models used by rural residents and tourists.

What a bulk SMS send to Mexico costs

Every message is priced at $0.01297 per segment to Mexico. Texts over 160 GSM-7 or 70 Unicode characters are split into segments, so a two-segment text costs twice as much.

Messages	1 segment	2 segments
1	$0.01297	$0.02594
1,000	$12.97	$25.94
10,000	$129.70	$259.40
100,000	$1,297.00	$2,594.00

Number format in Mexico

Mobile numbers in Mexico have 10 digits after +52 and no trunk prefix, so the local form 222 123 4567 becomes +52 222 123 4567 in the to field.

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

Mexico spans several time zones, from UTC-8 in Tijuana to UTC-5 in Cancun (January offsets). A send_at of 15:00 UTC lands at 09:00 in Mexico City in January; for a nationwide reminder, split the list by region and give each batch its own send_at.

Send to Mexico with one request

The answer comes back at once with the message id, the country the number was matched to (MX) 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.

Should messages be in Spanish or English?

Spanish is the primary language in Mexico and should be used for most audiences. English can be added for tourists or expatriates.

How do I handle peak tourist seasons?
