How Does SIM Card & Internet Work in Mexico?
Last verified: 2025-06 · Americas
1The Quick Answer
Telcel has the best nationwide coverage; buy a SIM at any OXXO store, or use an Airalo eSIM before you arrive.
2What You Need to Know
Telcel is Mexico's largest network and offers the widest coverage including rural and coastal areas. Prepaid SIM cards are sold at OXXO convenience stores nationwide without requiring ID in most cases, and data plans are affordable. AT&T Mexico is a good alternative with solid data speeds in cities. Airalo eSIM works well for travellers wanting to set up connectivity before landing. Hotel and café Wi-Fi is widely available but can be slow; a local SIM is strongly recommended for reliable maps, Uber, and translation.
