Stay Connected in Mexico City
Network coverage, costs, and options
Connectivity Overview
Mexico City's connectivity situation is actually pretty solid for a metropolis of its size. You'll find decent 4G coverage across most of the city, with 5G gradually rolling out in central areas and business districts. The three main carriers—Telcel, AT&T Mexico, and Movistar—all offer reliable service, though coverage quality drops off noticeably once you venture into some of the outer neighborhoods or mountainous areas surrounding the city. Most cafes, restaurants, and hotels offer WiFi, though speeds and reliability vary wildly. For travelers, the main decision comes down to whether you want the convenience of an eSIM you can activate before landing, or the potentially lower cost of picking up a local SIM card. Either way, staying connected here is straightforward enough—it's not like you're heading somewhere remote.
Get Connected Before You Land
We recommend Airalo for peace of mind. Buy your eSIM now and activate it when you arrive—no hunting for SIM card shops, no language barriers, no connection problems. Just turn it on and you're immediately connected in Mexico City.
Network Coverage & Speed
Telcel dominates the Mexican market and generally offers the most extensive coverage throughout Mexico City and beyond—if you're planning day trips to places like Teotihuacan or the surrounding pueblos, Telcel tends to maintain signal where others drop off. AT&T Mexico has improved significantly in recent years and offers competitive speeds in urban areas, while Movistar sits somewhere in the middle for both coverage and pricing. 4G speeds are typically adequate for video calls, navigation, and streaming, though you might hit congestion during peak hours in busy areas like Polanco or Roma Norte. 5G is expanding but still patchy—you'll find it in spots around Reforma and Santa Fe, but it's not something to count on yet. Network speeds generally range from perfectly usable to quite good, depending on your location and time of day. Worth noting that indoor coverage in older buildings can be hit or miss, as those thick colonial walls don't play nicely with mobile signals. The metro system has WiFi at many stations, though it's often crowded and slow.
How to Stay Connected
eSIM
eSIMs have become increasingly practical for Mexico City, and honestly, they're hard to beat for convenience. You can sort everything out before your flight, land with immediate connectivity, and avoid the airport SIM card kiosks entirely. Providers like Airalo offer Mexico-specific plans that work across all major carriers, typically running around $15-25 for 5-10GB depending on your data needs. The main advantage is simplicity—no hunting for a SIM shop, no language barriers, no worrying about getting overcharged at the airport. The downside? They're generally more expensive per gigabyte than local SIMs, and you can't just pop into a store if something goes wrong. That said, for most travelers staying a week or two, the price difference is maybe $10-15 total, which feels worth it for the hassle you're avoiding. Your phone needs to be eSIM-compatible and unlocked, obviously.
Local SIM Card
If you're committed to getting a local SIM, you've got options. You'll find official carrier stores throughout the city—Telcel and AT&T have shops in most major neighborhoods and shopping centers. The airport has kiosks too, though prices there tend to run about 20-30% higher than what you'd pay at a regular store in the city. You'll need your passport for registration (it's a legal requirement in Mexico). A tourist-friendly prepaid plan typically costs around 200-300 pesos ($10-15 USD) for a starter package with a few gigabytes of data. OXXO convenience stores also sell SIM cards and top-up cards, which is handy for recharging. Activation is usually straightforward, though you might need basic Spanish or a translation app to navigate the process. The main hassle is just the time investment—finding a store, waiting in line, getting everything set up. If you're staying longer than a month, though, this route makes more financial sense.
Comparison
Here's the honest breakdown: Local SIMs are cheapest if you're counting every peso, running maybe $10-15 versus $20-30 for an eSIM with comparable data. International roaming from your home carrier is almost always the most expensive option unless you've got some special travel plan—expect $10/day or more, which adds up fast. eSIMs split the difference: more expensive than local SIMs but way more convenient, and you're connected the moment you land. For most travelers staying under a month, the eSIM convenience factor outweighs the modest cost difference.
Staying Safe on Public WiFi
Mexico City's cafes, hotels, and airports all offer public WiFi, but here's the thing—you're sharing those networks with everyone else, and not all of them have good intentions. When you're logging into banking apps, booking accommodations, or accessing anything with your passport information, you're potentially exposing sensitive data on unsecured networks. Travelers are particularly attractive targets since they're often accessing financial services and making bookings while on the move. A VPN encrypts your connection, which essentially makes your data unreadable to anyone else on that network. NordVPN is a solid option that's straightforward to use—just turn it on before connecting to public WiFi. It's not about being paranoid; it's just sensible protection when you're handling important stuff over networks you don't control. Most decent VPNs cost less than a nice dinner out, which feels reasonable for the peace of mind.
Protect Your Data with a VPN
When using hotel WiFi, airport networks, or cafe hotspots in Mexico City, your personal data and banking information can be vulnerable. A VPN encrypts your connection, keeping your passwords, credit cards, and private communications safe from hackers on the same network.
Our Recommendations
First-time visitors should honestly just go with an eSIM through Airalo. You'll land with working data, can grab an Uber immediately, and won't waste precious vacation time hunting for a SIM shop or navigating the purchase in Spanish. The convenience factor is massive when you're already dealing with a new city. Budget travelers might be tempted by local SIMs since they're legitimately cheaper—if you're on an extremely tight budget, that $10-15 savings matters. That said, consider whether your time and the hassle of finding a carrier store is worth the difference. For most people, it's not. Long-term stays of a month or more should probably get a local SIM—the cost savings add up over time, and you'll want the flexibility of easily topping up and potentially getting better long-term rates. Business travelers really have no reason not to use an eSIM. Your time is valuable, you need immediate connectivity for meetings and emails, and the cost difference is negligible in a business context. Set it up before you fly and forget about it.
Our Top Pick: Airalo
For convenience, price, and safety, we recommend Airalo. Purchase your eSIM before your trip and activate it upon arrival—you'll have instant connectivity without the hassle of finding a local shop, dealing with language barriers, or risking being offline when you first arrive. It's the smart, safe choice for staying connected in Mexico City.
