Guatemala operates on 120 volts at 60 hertz using Type A and Type B electrical outlets, identical to North American standards. Plugs have two flat parallel pins or two flat parallel pins with a round grounding pin. Devices designed for European 220-240 volt systems require voltage converters in addition to physical adapters. Guatemala City and Antigua Guatemala offer consistent electricity supply in commercial zones, but power outages occur weekly in rural departments including Alta Verapaz, Petén, and Huehuetenango. Hotels above mid-range price points typically maintain backup generators. Carrying a portable battery pack proves essential when traveling outside urban centers, particularly in the Petén lowlands where infrastructure gaps are widest.
Guatemala uses the quetzal as its official currency, abbreviated GTQ and named after the resplendent quetzal bird. As of 2025, exchange rates fluctuate between 7.70 and 7.90 quetzales per US dollar, though rates change daily based on central bank policy and international markets. The US dollar circulates informally in tourist zones including Antigua Guatemala, Panajachel, and Flores, with some businesses accepting dollars at slightly disadvantageous rates favoring the merchant. ATMs dispense quetzales and appear throughout Guatemala City, Antigua Guatemala, Quetzaltenango, and other departmental capitals. Banco Industrial, Banrural, and BAM maintain the most extensive ATM networks. Daily withdrawal limits range from 3,000 to 5,000 quetzales depending on the bank and account type. ATM availability decreases sharply outside cities. Huehuetenango and Cobán offer multiple machines, but villages surrounding Lake Atitlán often have one shared ATM that runs out of cash on weekends. Carrying mixed denominations of quetzales solves payment problems in markets and with drivers who often claim insufficient change for 100 quetzal notes.
Credit cards function at mid-range and upscale hotels, restaurants charging above 80 quetzales per entrée, and established tour operators. Visa and Mastercard acceptance far exceeds American Express or Discover. A three percent foreign transaction fee applies to most international credit cards unless specifically waived by the issuer. Card fraud occurs with sufficient frequency that using ATMs inside bank branches during business hours rather than standalone street machines reduces risk. Skimming devices have been documented at machines in Guatemala City's Zona 1 and near the Central Market. Small businesses, comedores serving local food, chicken bus operators, and artisan vendors in Chichicastenango and other markets operate cash-only. Calculating a daily budget of 250 to 400 quetzales for meals, local transport, and incidentals requires carrying that amount in cash when moving outside established tourist infrastructure.
Mobile phone service in Guatemala operates on GSM 850 and 1900 MHz bands. Tigo, Claro, and Movistar provide the three major networks. Tigo maintains the strongest coverage in rural Petén and the Cuchumatanes Mountains, while Claro dominates Guatemala City and the central highlands. Tourist SIM cards cost between 20 and 40 quetzales and require presenting a passport at official carrier stores. Arbitrary passport photo requirements change by location, so purchasing SIMs at airport locations immediately after arrival avoids complications. Prepaid data packages start at 25 quetzales for one gigabyte valid seven days. A 10 gigabyte package valid 30 days costs approximately 100 quetzales as of early 2025. Coverage along the Carretera Interamericana between Guatemala City and the Mexican border at La Mesilla remains consistent. Dead zones appear in the Sierra de las Minas Biosphere Reserve, along unpaved sections approaching Semuc Champey, and throughout portions of the Maya Biosphere Reserve north of Flores. Livingston on the Caribbean coast has functional mobile service, but the boat journey along Río Dulce enters extended service gaps.
Internet access in Guatemala City, Antigua Guatemala, and Quetzaltenango meets expectations for video calls and file uploads. Hotels, cafes, and coworking spaces advertise speeds between 10 and 50 megabits per second, though actual performance often falls to half the stated rate during evening hours. Café operators in Antigua Guatemala near the central park provide reliable connections used by remote workers. Panajachel and other Lake Atitlán villages offer functional WiFi at hostels and restaurants, but speeds rarely exceed 5 megabits and drop entirely during storms that damage microwave transmission equipment. Flores provides adequate internet for basic email and messaging. Venturing into Tikal National Park or communities deeper in Petén eliminates reliable internet access. Villages in the Ixil region including Nebaj and communities in the Cuchumatanes operate with intermittent satellite connections when they have internet at all. Planning to upload photos, access maps, or conduct business requiring bandwidth means completing those tasks in cities before departing for remote areas.
Tap water in Guatemala carries parasites and bacteria that cause digestive illness in travelers regardless of immunity developed elsewhere. This applies uniformly across Guatemala City, Antigua Guatemala, and every other location. Hotels above budget tier provide purified water in rooms via five-gallon dispensers or bottles. Restaurants serving international clientele use purified water for ice and food washing, but comedores and street food vendors use tap water. Buying bottled water remains the single non-negotiable practice. A 1.5 liter bottle costs 5 to 7 quetzales in tiendas and convenience stores. Refusing ice in beverages, avoiding uncooked vegetables unless confirmed washed in purified water, and declining fruit salads from uncertain sources prevents the most common traveler illness. Portable water filters or ultraviolet purification pens reduce plastic waste for travelers spending weeks in country, but purification tablets impart an unpleasant taste that most users abandon within days. Dehydration at higher elevations including Quetzaltenango at 2,300 meters and Tajumulco at 4,220 meters requires consuming three to four liters of water daily.
Public toilets in Guatemala charge between 2 and 5 quetzales at bus terminals and markets. Attendants provide small amounts of toilet paper with entry. Paper goes in waste bins beside toilets rather than into the bowl, as sewage systems throughout the country lack capacity to process paper without clogging. This practice extends to all categories of accommodation from hostels to luxury hotels. Signs in bathrooms make the requirement explicit. Gas stations along major highways maintain restrooms of widely varying cleanliness. Filling stations near Antigua Guatemala and on the route to Tikal generally stock soap and maintain functional facilities. Stations in smaller towns may offer only a concrete room with a hole and a bucket of water. Carrying personal toilet paper, hand sanitizer, and wet wipes addresses gaps in public facilities. Women traveling in rural areas face particularly limited options, as many villages lack public facilities entirely.
Guatemala operates on Central Standard Time year-round, equivalent to UTC minus six hours. The country does not observe daylight saving time. When the United States and Canada shift clocks forward in March, Guatemala becomes one hour behind Central Daylight Time in those countries. When those countries revert in November, Guatemala returns to time equivalence with central North America. This affects flight schedules and border crossing hours with Mexico, which does observe daylight saving in states near Guatemala.
Tipping practices in Guatemala follow norms distinct from North American percentages. Restaurants in tourist zones increasingly add a 10 percent service charge directly to bills, labeled "propina sugerida" or suggested tip. When this appears on the bill, additional tipping is optional. When no service charge appears, leaving 10 percent for adequate service and 15 percent for exceptional service follows local upper-income practice. Budget eateries serving casado-style meals for under 30 quetzales per plate do not expect tips, though rounding up the bill or leaving 5 quetzales is received positively. Tour guides working for established operators expect 50 to 100 quetzales per day per traveler depending on tour length and group size. Private drivers on full-day excursions receive 75 to 150 quetzales. Bellhops at mid-range and luxury hotels receive 5 to 10 quetzales per bag. Gas station attendants in Guatemala still provide full service, pumping fuel and cleaning windshields. They receive 5 quetzales or drivers round up the total. Tipping bathroom attendants 1 or 2 quetzales beyond the entrance fee shows standard courtesy.
