Most newcomers treat getting a local SIM card as a minor errand. It’s not \u2014 in Mexico, your phone number quietly becomes the backbone of your entire digital identity, and losing access to it can be far more disruptive than it sounds.<\/p>\n\n\n\n
Mexican banking apps \u2014 BBVA, Banorte, and the rest \u2014 require a Mexican number for two-step verification, and they generally can’t send those codes to a foreign number at all. The same goes for government portals like SAT, for Uber and DiDi accounts, and for WhatsApp, which functions as the default communication channel for everything from your property manager to your doctor’s office here. If your number is tied to all of that and you lose it, you’re not just missing calls \u2014 you can lose access to banking, official accounts, and daily communication in one shot.<\/p>\n\n\n\n
Mexico now requires all +52 phone numbers to be registered using your passport and CURP by June 29, 2026, in order to keep the line active. If you’re getting a Mexican SIM, plan on completing this registration promptly \u2014 an unregistered line risks suspension, which cascades into every account tied to that number.<\/p>\n\n\n\n
