eSIM Travel Tips for Mexico

Currency in Mexico
Mexico uses the Mexican peso (MXN). Current rates are roughly £1 to 23-25 MXN. Mexico offers good value for British visitors in restaurants, taxis, and local markets. Keep your HelloRoam eSIM active to use currency converters, locate ATMs, and access Uber or Didi for safe transport.

More remote cenotes and jungle areas between the highway and the coast can have weaker signal. Download offline maps before visiting remote natural sites.
