1. eSIM — The Best Option for Most Travelers
An eSIM is a digital SIM built into your phone. Buy it online before your flight, scan a QR code, and you're connected the moment you land in Mexico.
Why eSIM wins:
- Ready before you land — no airport lines, no store visits
- Keep your home SIM active (dual SIM) — WhatsApp stays on your number
- Cheaper than airport SIMs and roaming
- mexsim.co plans include unlimited WhatsApp, Instagram, Facebook, TikTok
Who it's NOT for:
- Phones older than 2018 without eSIM support
- Carrier-locked phones (must be unlocked)
2. Local SIM Card — Cheapest Overall
Buy a physical Telcel SIM at any OXXO convenience store (there's one on every corner in Mexico) or at a Telcel store.
- Price: $100-500 MXN ($5-27 USD) for SIM + data
- Carrier: Choose Telcel for best coverage
- Downside: Must find a store, staff may not speak English, replaces your home SIM
3. Airport SIM — Convenient but Pricey
Telcel and AT&T counters at Mexico City, Cancun, and Guadalajara airports. Good if your phone doesn't support eSIM.
- Price: $150-600 MXN ($8-32 USD) — tourist markup
- Wait: 15-30 minutes after international flights
- Tip: Ask for Telcel specifically — best network
4. Pocket WiFi Rental — For Groups or Old Phones
Rent a mobile hotspot device that creates a WiFi network for your phone and travel companions.
- Price: $7-15 USD/day ($50-100/week)
- Pros: Connect multiple devices, no phone compatibility issues
- Cons: Must carry extra device, battery dies, pickup/return logistics
5. International Roaming — Most Expensive
Your home carrier's Mexico roaming. Most charge $10-15/day.
- Exception: T-Mobile Magenta Max includes Mexico at no extra cost
- For everyone else: A week of roaming costs more than a month of eSIM
6. Free WiFi Only — Not Recommended
Hotels, restaurants, and some public spaces have free WiFi. But it's slow, unreliable, and you have zero connectivity when you need it most — navigating streets, hailing rides, and communicating with hotels/drivers.
Mexico's Networks: Quick Guide
- Telcel = best coverage everywhere. Choose this.
- AT&T Mexico = good in cities, weaker elsewhere.
- Movistar = cheapest but weakest coverage. Avoid for travel.
Our Recommendation
Get an eSIM from mexsim.co if your phone supports it ($11+ for 7 days). If your phone doesn't support eSIM, buy a Telcel SIM at the airport or any OXXO store when you arrive.
