What Is an e SIM? How eSIM Works in Mexico
An eSIM card is a digital SIM built into your phone. There is no plastic chip and no SIM tray to open. Scan a QR code to activate your e SIM in under two minutes on any eSIM compatible iPhone or Android. It works as a prepaid international data plan for Mexico travel with no airport SIM shop queue, no replacement SIM card, and no carrier contract. Mobile data through an eSIM connects to local in-country networks, giving you the same wireless connectivity as a resident rather than a roaming tourist. Follow the step-by-step setup guide to get connected before your flight from Heathrow, Gatwick, or any UK airport. guide

eSIM Travel Tips for Mexico
Install your eSIM before your transatlantic flight to Mexico
Set up your HelloRoam eSIM at home before your British Airways, Virgin Atlantic, or connecting flight to Mexico. Enable data when you land in Cancún or Mexico City and you are connected in the arrivals hall. No SIM card hassle on arrival.
Currency in Mexico
Mexico uses the Mexican peso (MXN) and 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.
Coverage along the Riviera Maya
The Riviera Maya corridor from Cancún to Tulum has good 4G coverage along the main highway (Federal Highway 307). Resort hotels and Playa del Carmen have strong coverage. More remote cenotes and jungle areas between the highway and the coast can have weaker signal. Download offline maps before visiting remote natural sites.

Keep your UK SIM active for banking
UK banks send SMS verification codes for overseas transactions in Mexico. Keep your British SIM active in your second slot while using HelloRoam for Mexican data. You will receive any security verification codes on your regular UK number.
Mobile networks in Mexico: what British travellers need to know

£3.73–£11.19/day
UK plans do not include Mexico in their European roaming allowances, so EE, Vodafone UK, and O2 charge daily international rates for data. Over a two-week Mexico holiday those charges pile onto your monthly bill. HelloRoam fixes the cost before you fly.

Best time to visit Mexico from the UK
Mexico's Caribbean coast (Cancún, Playa del Carmen, Tulum) is best from December to April, dry, sunny, and 26°C to 32°C. Hurricane season runs June to November with September being the peak risk month. The Pacific coast (Puerto Vallarta, Los Cabos) has a slightly different weather pattern with rain from June to October. Mexico City is pleasant year-round at 18°C to 24°C given its high altitude. British families often visit during school Easter and summer holidays despite the heat. December and January are peak luxury resort season.
