Best eSIM for Mexico

Mexico is a long way outside UK roaming zones, so most networks charge around £7 to £8 a day there. A travel eSIM for a fortnight costs less than two days of that.

Which network matters in Mexico

Telcel has the widest coverage in Mexico. Movistar and AT&T are fine in the cities and the big resorts but can drop out in smaller places. If you are touring rather than staying in one hotel, a plan that can use Telcel (Holafly and Ubigi list it) is the safer choice.

Which eSIM to pick

  • Two weeks in Cancun or the Riviera Maya: 10GB is plenty for most people. Nomad's 10GB for 30 days is one of the cheapest.
  • Touring or road trips: choose a plan with Telcel for the best coverage.
  • You need to make local calls: Airalo sells Mexico plans with minutes and texts included, handy for booking tours or taxis.
  • Heavy use: the unlimited plans from Nomad, Airalo or Holafly are around £17 to £18 for a week. Nomad slows you down after a daily limit, so read the small print.
