What a typical Mexico trip looks like — and what it needs
Three patterns dominate. First: Cancún, Tulum, Playa del Carmen — beach, all-inclusive, day trips to Chichén Itzá. Second: Mexico City, three or four days, museums and food. Third: an open-ended drive — Oaxaca, Mérida, San Cristóbal — that stretches to a month. Each needs different things from a connection. None of them needs a 30-day SIM bought at a tourist counter.
Roamzy charges $3.28 per gigabyte in Mexico. That's $0.0032 per megabyte, billed in real time as your phone uses data on Mexican networks. No subscription. No expiry on the unused balance. No minimum bundle. One per-MB rate across 192 countries — the shape of the invoice, not a marketing line.
How much will Roamzy actually cost on this trip?
A typical visitor to Mexico uses 0.5–1.2 GB per day: Maps in CDMX or down the Yucatán highway, Uber/Didi/Cabify, the camera-translator on a comida corrida menu, Rappi for delivery, contactless via Apple Pay or Google Pay (CDMX is largely card-friendly; smaller towns lean cash and OXXO), the occasional video call. Resorts handle some load on Wi-Fi. Call it 1 GB/day for the math:
| Trip length | Roamzy ($3.28/GB) | Tourist roaming pass | Local SIM at the airport |
|---|---|---|---|
| 3 days | $24.58 | $25–55 | $15–35 + paperwork |
| 1 week | $57.34 | $45–100 | $25–50 + 30-day cap |
| 2 weeks | $114.69 | $80–180 (often two passes) | $35–70 + ID |
Competitor prices in columns 3 and 4 are 2025 ranges based on typical offerings; exact figures depend on your home carrier and the airport store you visit. Roamzy's rate in column 2 is our actual published rate from the pricing page.
Local SIMs at CUN, MEX, or GDL are widely available, but tourist tariffs are usually pricier than the same network sells to residents, and KYC at the counter eats a half-hour after a long flight. If your trip is short and the math is close, the eSIM saves the queue.
Where does Roamzy work in this country?
Mexican networks vary widely between dense urban coverage and rural reality. The shape on the ground:
- Mexico City, Guadalajara, Monterrey, Puebla, Querétaro — 5G in the centers, dense LTE through the metro areas
- Cancún, Playa del Carmen, Tulum — solid LTE through the resort corridors and along the highway
- Yucatán interior (Mérida, Chichén Itzá, Valladolid, cenotes) — workable LTE in towns, weaker on the back roads
- Oaxaca, San Cristóbal, the Sierra towns — workable in town centers, gaps on the mountain roads between them
- Baja California (Cabo, La Paz, Loreto) — LTE in the resort zones; the Trans-Peninsular highway has long quiet stretches
- Mexico City Metro — signal works on platforms; older tunnel runs drop briefly
Driving between cities, expect 4G on the toll roads (cuotas) and patchy on the libres. Offline maps earn their keep.
Why is per-megabyte pricing simpler than packages?
A Mexico trip is already a stack of small frictions: tipping that's different from the US norm, an OXXO payment system tourists don't understand, a card your bank flagged on the second taco truck. The data plan should not also be a problem.
Roamzy is built around that. No first-purchase promo. No fine-print throttling. No auto-renewal six months later. One rate, billed by the megabyte, balance carries.
How do I install my Roamzy eSIM?
| Plug type | Voltage | Frequency | iOS | Android |
|---|---|---|---|---|
| Type A, B | 127 V | 60 Hz | iPhone XS+ | Pixel 3+, Galaxy S20+ |
- Sign in to Roamzy via Telegram or Google
- Top up the eSIM with a minimum of 20 USDT — stablecoins, no cards, no banks, no FX surcharges
- The QR code appears in the dashboard once payment confirms
- Settings → Cellular → Add eSIM → scan QR
- The counter starts the moment you land at CUN, MEX, GDL, or any other gateway
Outlets are 127 V — bring an adapter if you're coming from the EU. Supported stablecoins, networks, and common iPhone/Android setup errors are in the FAQ.
What are Roamzy's honest limitations?
Three traps Roamzy doesn't have because they were never built in.
- No welcome promo that bait-and-switches your second top-up. The rate on top-up #1 is the rate on top-up #20.
- No fine-print throttling. One rate, full speed — first GB and the hundredth cost the same $0.0032/MB.
- No auto-renewal you forgot to cancel. Balance runs out, the eSIM stops.
It's not a marketing gimmick — it's an engineering decision born from indifference to gimmicks. You can't make a tariff cheaper than no fine-print and no expiry — so we don't.
What if my trip extends to other countries?
Mexico often pairs with neighbors. Same Roamzy account, same logic at the border:
- USA — frequent connection point via the northern border or DFW/MIA
- Guatemala — common southern continuation by bus or short flight
