Hi there Omar, thanks for taking the time to ask us your question about the Samsung Galaxy S25 Ultra. The advertised (U.S. version) Galaxy S25 Ultra is compatible with the following U.S. carriers: AT&T, Boost Mobile, Cricket, Google Fi, H2O Wireless, Mint Mobile, Sprint, T-Mobile, Ultra Mobile, US Cellular, and Verizon. We suggest reaching out to a compatible carrier to inquire if this device would be functional in Mexico. If you have any other questions, feel free to contact Support. Thank you for choosing Samsung! - Debra
