SMS Availability on Mexico Local Phone Numbers
 Learn why SMS is no longer supported on Mexico local phone numbers, how to identify affected numbers, and which communication methods remain available. 
Overview

Mexico local phone numbers no longer support SMS due to an upstream carrier migration. This applies to both existing Mexico local numbers that previously supported SMS and newly purchased Mexico local numbers. HighLevel now displays an SMS unavailable status pill so admins can identify the restriction directly from the Phone Numbers table. Voice continues to work, and WhatsApp continues to work where applicable.

Why the SMS Unavailable Status Appears

The status pill helps admins distinguish a permanent carrier-related capability change from a temporary sending or configuration problem.

The underlying service provider migrated affected Mexico local numbers to a new carrier. As a result, SMS capability was permanently removed from Mexico local numbers. HighLevel surfaces this restriction directly in the Phone Numbers table so admins can identify the change before attempting to send SMS.

Recommended Alternative

The in-product status provides additional context for affected numbers and is intended to point admins toward a supported next step.

Needs Confirmation

The release states that the status pill points users to a working alternative, but the exact recommended alternative and tooltip copy were not supplied. Do not document Sender ID registration, short codes, another number type, or another messaging channel as the recommended replacement until the product recommendation is confirmed.
