The service, called BAIT or "Bodega Aurrera Internet y Telefonia," has serviced more than 2 million Mexicans, executives said.

"We now represent nearly 2% of total mobile telephone lines in Mexico since we launched the service less than two years ago," said Chief Growth Officer Beatriz Nunez.

The company is also aiming to have an all-electric delivery fleet by 2027, an executive said.

Walmex began the switch last year, said Senior Vice President of Real Estate Gaston Wainstein.
