Money, SIM cards, internet

Money

Guatemala uses the quetzal (Q). Approximate rate as of mid-2026: 1 USD = Q7.6: Q7.8. ATMs are reliable in Panajachel, San Pedro La Laguna, and Santiago Atitlán. Most other lake towns have at least one ATM but they run out of cash on weekends and holidays. Pull what you need before Sunday.

Cards are accepted at boutique hotels, restaurants pitched at travelers, and a handful of bigger shops. As of 2026, roughly 80% of restaurants in Panajachel and around 60% of spots lakewide accept cards, and tap-to-pay terminals show up in tourist-facing places in Pana, San Marcos, and San Pedro. Comedores, mercados, lanchas, tuk-tuks, and most local businesses are still cash-only. Carry small bills. A Q200 note can be hard to break in a small town.

Cash still gets you the cleanest price. Card payments almost always carry a roughly 5% surcharge, with the occasional operator pushing it to 10%, and some shops do cash back at a 20% premium when ATMs run dry. ATM withdrawal limits per transaction are typically Q1,500: Q2,000 (~$200: $260 USD). Foreign-card fees usually run $3: $6 USD per withdrawal plus your home bank's overseas fee, which works out to about 7% all-in.

A useful middle option: Colibri runs a cash delivery service. Pay by card on their web app and they bring the cash to you. It works about 75% of the time and the fee is 10%, which compares well against the 20% in-store cash-back markups. Worth knowing about if you're across the lake and the trip into Pana isn't worth a full day. Banking deep dive for residents.

SIM cards

Two carriers cover Lake Atitlán: Tigo and Claro. Coverage at the lake is comparable; both work in every town. Most travelers and residents pick whichever has a shop closest to where they're standing.

The simple path: walk into any Tigo or Claro shop with your passport and ask for a prepaid SIM with a data plan. The shop staff will install it, top it up, and confirm it works before you leave. Plans range from a few days of data to monthly. Prices change often, so we are not printing numbers that go stale: the shop will quote you the current rate.

Where to find a shop: search "Tigo" or "Claro" in Google Maps. There are shops in Panajachel (multiple, on Calle Santander and Calle Principal), San Pedro La Laguna, Santiago Atitlán, Sololá, and at La Aurora airport in Guatemala City if you want to land with data already working.

eSIM option: If your phone supports eSIM and you'd rather skip the shop visit, services like Airalo, Holafly, and Nomad sell Guatemala data plans you activate before arrival. Worth it for a short stay; for a longer stay, a physical Tigo or Claro SIM is cheaper per GB.

Internet

Most cafes, hostels, and hotels at the lake have wifi. Speeds vary: in Panajachel, San Pedro, and the bigger towns, fiber connections deliver real working speeds. In smaller villages (Tzununá, Jaibalito, parts of Santa Cruz), wifi exists but can be slower or flicker during storms. If you need a guaranteed video call, sit in a coworking space or a cafe known for good internet, and have your phone tethering as backup.

Power cuts happen, especially in wet season (May: October) when storms knock lines down for an hour or two. Keep your laptop charged. Most coworking spots have UPS battery backup so they stay online through short outages. Remote work deep dive (towns, coworking, ISPs).

Bottom line

• Pull cash from an ATM in Panajachel, San Pedro, or Santiago. Carry small bills.
• Walk into a Tigo or Claro shop with your passport for a SIM. Don't overthink which carrier.
• Wifi at the lake is fine for normal use. For mission-critical calls, work from a coworking space.
