Mexico eSIM: 5G in Cancún, Mexico City & Beyond — No Passport

Major change — as of January 9, 2026, all new prepaid SIM cards in Mexico require mandatory passport registration and a selfie verification. This applies to Telcel, AT&T, and Movistar. Tourists now must: (1) visit a store or Oxxo; (2) show passport and have it scanned; (3) upload a selfie for facial verification; (4) wait for approval. This adds 15-30 minutes of hassle. Roami requires none of this — no passport, no selfie, no store visit. Buy online, scan QR, done.

Yes — Mexico’s 5G network is expanding rapidly. Mexico City, Cancún, Guadalajara, and Monterrey have 5G coverage with typical speeds of 50-200 Mbps. At Cancún’s hotel zone, Chichen Itza (4G), and Mexico City’s historic center, you’ll get reliable coverage. In smaller towns and along highways, 4G is standard with speeds of 10-40 Mbps — fine for maps, messaging, and social media. Roami auto-connects to Telcel for the best rural coverage and AT&T/Movistar in cities.

Telcel has the most extensive coverage nationwide (especially at ruins and rural areas) — the best choice for travelers visiting Chichen Itza, Teotihuacan, or Tulum. AT&T has strong 5G in Mexico City and Cancún, and offers easy roaming to the US/Canada. Movistar is competitive in urban areas but has less rural coverage. With Roami, you don’t choose — your eSIM auto-switches to whichever carrier has the strongest signal at your location.

Yes — Roami eSIM works across North America. This is a major advantage over Mexican local SIMs: Telcel’s “free” North America roaming has strict rules — service is suspended if you use it outside Mexico for more than 29 consecutive days and foreign usage exceeds domestic. AT&T has similar restrictions. Roami offers transparent regional coverage with no anti-abuse clauses or surprise suspensions.

Yes — it’s a waste of money and data. Telcel’s cheapest plan is 7 days ($50 MXN ≈ $3 USD) with limited data. AT&T’s minimum is 14 days ($100 MXN), Movistar’s is 15 days ($75 MXN). A 5-day tourist buying a 7-day plan wastes 29% of the plan. AT&T’s 14-day plan wastes 64%. Roami offers 3, 7, 15, and 30-day plans starting from $1.99 — no forced minimum, no waste.

Yes — Telcel has reliable 4G coverage at all major archaeological sites. Chichen Itza has 4G from Telcel and AT&T. Teotihuacan (just outside Mexico City) has strong 4G/5G. Tulum has good 4G coverage. For remote ruins (e.g., Calakmul, Palenque), coverage can be patchy — we recommend downloading offline maps before visiting remote sites. Roami auto-connects to Telcel for the best rural coverage.

Yes — Unefon (which uses Movistar’s network) explicitly bans hotspot/tethering on its prepaid plans. Movistar prepaid throttles to 1Mbps after 1GB daily usage, resetting at midnight — making hotspot frustratingly slow. Roami allows full-speed hotspot sharing with no daily caps and no bans.

Telcel officially stopped supporting PayPal for top-ups in 2025. Your options now are: (1) international credit card (may be rejected); (2) cash at Oxxo convenience stores (need to find one, carry cash). Roami accepts Visa, Mastercard, AMEX, Apple Pay, Google Pay, and PayPal — no rejections, no Oxxo trips.

No problem. Log into your Roami account to re-download the QR code — takes about 1 minute. We recommend saving it as a screenshot or PDF when you first receive it, just in case.

The plan validity starts when you connect to a local network in Mexico, not when you buy or install it. So you can purchase and install weeks before your trip without losing any plan days. A 7-day plan gives you 7 full days from first connection.
