International flights land at Terminal 2; domestic ones at Terminal 1. Reports from 2026 mention Telcel and other carrier kiosks in the arrivals area and small shops selling SIM cards from Mexican networks, but none is guaranteed to be open, especially for late arrivals and in peak season. Prices at the airport are higher than in town, where Telcel shops and OXXO convenience stores in San José del Cabo and Cabo San Lucas sell the same prepaid plans.
After customs at Terminal 2 you walk through a corridor of timeshare and tour sellers, the "shark tank". Some present themselves as transport or information desks: they are not where SIM cards or your driver are.
Every new Mexican line must be registered to you before it works normally, with your passport. A travel eSIM from abroad needs no registration: see Mexico SIM card or eSIM in 2026. Facts checked in October 2026.
