The trip is the highlands and a couple of buses
A typical Guatemala route runs Guatemala City → Antigua → Lake Atitlán → Quetzaltenango → maybe Semuc Champey or Flores for Tikal. That's a country reachable in a week, served by chicken buses and shuttle vans, with cobblestones in Antigua and a volcano on the horizon most evenings. Connectivity matters because the route relies on it: the shuttle confirmation in WhatsApp, the bus driver's voice note about a delay, the hostel's location pin in San Pedro La Laguna.
Roamzy charges $4.20 per gigabyte in Guatemala. That's $0.0041 per megabyte, billed in real time on Guatemalan networks. No subscription, no expiry, no minimum bundle. One per-MB rate across 192 countries is the shape of the invoice, not a marketing line.
How much will Roamzy actually cost on this trip?
A typical visitor uses 0.5–1 GB per day: maps to the hostel from the bus station in Antigua, the camera-translator on a Spanish menu, ride-hail in Guatemala City, the boat schedule for the lake, video calls home over a Mayan internet pause. Call it 1 GB/day for the math:
| Trip length | Roamzy ($4.20/GB) | Tourist roaming pass | Local SIM at GUA |
|---|---|---|---|
| 3 days | $11.97 | $15–40 | $5–15 + passport |
| 1 week | $27.93 | $30–80 | $8–20 + 30-day cap |
| 2 weeks | $55.86 | $70–140 (often two passes) | $12–25 + cap |
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.
A local SIM at La Aurora is cheap, but it eats half an hour of arrival time, and the data window starts ticking from purchase regardless of when you actually open the SIM. With an eSIM, the counter only starts when your phone uses bytes.
Where does Roamzy work in this country?
Guatemala is mostly mountainous, mostly mid-density, and the network reflects it:
- Guatemala City, Antigua, Quetzaltenango — 4G/LTE at 95%+, 5G in central districts of the capital
- Lake Atitlán (Panajachel, San Pedro, Santa Cruz) — solid LTE in the larger towns, weaker on the boats and patchier in San Marcos and Tzununá
- The CA-1 and CA-9 highways — continuous LTE on the asphalt, gaps in the high passes between Chichicastenango and Huehuetenango
- Semuc Champey and the Cobán region — fine in town, intermittent on the descent into the canyon and the dirt road to Lanquín
- Flores and Tikal — LTE in town, weakening as you enter the park; near-nothing among the ruins
- The Pacific coast (Monterrico, Champerico) — works in the villages, often weaker on the black-sand beaches
For Tikal at sunrise, download offline maps the night before in Flores. The howler monkeys won't care that you have data.

What are Roamzy's honest limitations?
Three traps Roamzy doesn't have because they were never built in. No welcome promo on the first top-up that flips on the second. No fine-print throttling — "5 GB at full speed, then 128 kbps." No auto-renewal you forgot to cancel and discover six months later from a card you don't watch.
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 continues to other countries?
Guatemala is an entry point or an exit on most Central American routes:
- Mexico — north to Chiapas and San Cristóbal de las Casas via the La Mesilla crossing
- Belize — Flores to San Ignacio in a single shuttle, the eSIM picks up the Belizean network at the border
- Honduras — south through Esquipulas toward Copán Ruinas
