The Federal Telecommunications Commission (CRT) in Mexico announced that mobile phone lines ending in 0 were suspended starting August 15, 2026, and lines ending in 1 must be registered by August 31, 2026, or face suspension. ^[1] Specialists and academics recommend narrating personal economic situations to AI tools rather than uploading bank statements to protect financial privacy. ^[2] Users should never input identifiable personal data such as full names, bank account numbers, home addresses, RFCs, or CURPs into AI chat consultations. ^[3] If a user fails to register within the 72-hour grace period after the deadline, the service will be temporarily suspended, blocking standard calls, texts, and data, though emergency calls and civil protection alerts remain available. ^[4] Mobile lines in Mexico whose numbers end in 1 have until August 31, 2026, to complete their registration to avoid suspension of services including calls, messages, and mobile data. ^[5] The registration process is free and can be completed remotely through the centralized CRT portal at https://registratulinea.crt.gob.mx/ or in person at carrier centers. ^[6] Experts emphasize that AI does not replace the work of a professional financial advisor because systems generate responses based on training data which may contain biases or inaccuracies. ^[7] Experts warn that using AI to organize budgets and savings goals requires strict precautions to prevent fraud or unwanted exposure of banking information. ^[8]
