Business phone service / Mexico City, Mexico
Business phone service for Mexico City offices that work with the US and the rest of Latin America.
Mexico City offices often answer to a head office in the US or Spain and serve customers across Latin America. They need bilingual menus, calling to the US and other countries without fraud risk, and dial plans that match Mexico’s current numbering. Texwan sets up phone systems remotely and ships phones ready to use.
Mexican numbers come from providers licensed in Mexico, where available. We work remotely and do not claim a Mexican office or licence.

01 / Threat Briefing
Threat Briefing
Mexico moved to uniform 10-digit dialing on August 3, 2019, dropping the old 01, 044 and 045 prefixes, according to its telecom regulator. Older PBX dial plans still built around those prefixes can misroute calls. (Mexico regulator)
911 is Mexico’s national emergency number, so every phone on the system must be able to reach it directly. (Government of Mexico)

Three checks you can run yourself, with or without us.

Legacy and odd setups
Old phone systems in Mexico City? We can work with them.
Mexico City offices often still have Panasonic, NEC or Avaya systems with dial plans written before 2019. We can update or replace them, and keep the old system running alongside during the move.
