Cinémedios reported that Meta announced Muse’s arrival in Mexico on November 5, 2026, with Spanish-language access through the web, iOS and Android apps, and WhatsApp. One person’s report of a rejected card during an onboarding attempt outside the United States does not establish a signup rule for Mexico.

The brands named in the Mexico report

Cinémedios also named eight participating brands: Cinépolis, Coppel, Despegar, Kavak, Kueski, Liverpool, Rappi and Walmart México.

Does one card rejection establish a rule for Mexico?

No. A Reddit commenter said a card issued outside the United States was rejected during an individual Muse signup attempt. That is one person’s account of onboarding, not a country-wide access policy for Mexico.

A rejected card in one signup attempt describes that person’s experience, not a country-wide access policy.
