TL;DR: Always pay in Mexican pesos, not US dollars. Choosing local currency on card terminals avoids dynamic-currency-conversion markups of about 3–12%. Cards work widely in Mexico City, but taco stands, markets, and the Tren Ligero are cash-first — carry MX$300–500 in small bills per match day.
The one rule: decline dollar pricing
When a Mexico City card terminal asks whether to charge in dollars or pesos, always choose pesos. The dollar option, called dynamic currency conversion, lets the merchant's bank set the exchange rate and add a markup — typically 3–12%worse than letting your own bank convert. The same rule applies at ATMs: decline the “with conversion” offer and accept the peso amount. With five matches at Estadio Azteca through July 5, those percentages add up fast across a long stay.
Cash vs card across a match day
| Where | Pay with | Note |
|---|---|---|
| Hotels, supermarkets, chains | Card / contactless | Always choose pesos at checkout |
| Taco stands, markets, tianguis | Cash (pesos) | Small bills; many vendors take no cards |
| Metro & Tren Ligero | Movilidad Integrada card | Load with cash at station machines |
| Inside Estadio Azteca | Contactless / mobile wallet | Largely cashless; keep a backup card |
Withdraw pesos from a bank-branded ATM (BBVA, Santander, Banorte) rather than an airport kiosk, and take out a larger sum to spread the fixed fee. For the stadium's cashless setup, the cashless payment guide has the full breakdown, and the metro guide explains the Movilidad Integrada transit card.
Why your wallet needs data
Apple Pay, Google Pay, and your bank's fraud-verification texts all need a live connection — a declined-card scare abroad is usually just a missing data signal. Mexican carrier roaming runs roughly US$10–15 a day, while a travel North America eSIM on the Telcel network costs far less and is active before you land. Compare:
| Option | Cost | Setup time | Coverage |
|---|---|---|---|
| eSIM | Low (US$3–25) | ~5 min (pre-install on Wi-Fi) | Excellent (local carrier) |
| Carrier roaming | High ($10–15/day) | Instant (already enabled) | Medium (partner-dependent) |
| Pocket Wi-Fi | Medium | Airport pickup / rental | Good (extra device to charge) |
