Why does my signal drop in Guanajuato city?

The city's famous underground road tunnels and dense stone alleys block signal in places. Coverage is fine at street level and on plazas, so cache directions before ducking into the tunnels.

Is the airport far from San Miguel de Allende?

BJX airport sits roughly 90 minutes from San Miguel and under an hour from Guanajuato city. Keep data on to arrange a shuttle or ride, as timed transfers are the norm.

Good to know in Guanajuato

Guanajuato city is a warren of tunnels, stairways and one-way callejones where GPS gets confused underground. Download an offline map and note landmarks, as your blue dot drifts when you dip into the tunnels beneath the centre.

Best time to visit Guanajuato

October to April brings crisp, dry highland days; October's Cervantino festival packs Guanajuato city, and Day of the Dead in early November is especially atmospheric.

High-speed data, nothing to count

Priced per day — the longer you stay, the better the daily rate. Ideal for streaming, hotspot and longer trips where you'd rather not watch a data meter. A fair-use policy keeps speeds fast for everyone; see each plan for the detail.

Great for longer or open-ended trips
One price per day — no GB anxiety

By-the-GB plans
