Imagine landing in Mexico City for the opening match. Your group is meeting at the Angel of Independence, your digital tickets are in your app, and you need to call an Uber. But when you look at your phone, you see "No Service."
With the tournament spanning 16 cities and three countries, reliable data is your lifeline. Whether navigating a new subway system, coordinating with friends in a crowded fan zone, or needing emergency assistance, you need a plan that works everywhere.

North America has excellent 5G coverage in all host cities. However, crossing borders can trigger massive roaming charges, and stadium congestion can slow even the fastest networks to a crawl.
The biggest mistake fans make is assuming their home plan covers all three countries automatically. It often doesn't, leading to the dreaded "bill shock" upon return.
You have four main plays to choose from. Each has pros and cons depending on your itinerary and budget.
| Option | Pros | Cons | Best For |
|---|---|---|---|
| International Roaming | Easiest, keep your number | Expensive, data caps | Short trips, business travelers |
| Local SIM Card | Cheapest local rates, best signal | Physical swap, new number | Single-country stays (>1 week) |
| eSIM (Digital) | Instant setup, keep home SIM | Requires unlocked phone | Multi-country travelers |
| Portable WiFi | Connects multiple devices | Another device to charge | Groups, families |
