You step off the plane at Jorge Chávez International Airport, tired after a long flight, and head straight for the SIM card kiosk in the arrivals hall. It's 8:15 PM on a Friday. The kiosk is closed. The sign says it will reopen Monday morning. Your US phone, locked to your carrier, cannot use a local SIM anyway. You are now disconnected from ride-share apps, maps, and your hotel's confirmation number. This is the normal situation for late-arriving passengers. And it is only the first of several predictable traps that a careful traveler can avoid with advance knowledge.

This article is a walkthrough of those traps, based on repeated visits and conversations with locals who watch tourists stumble into the same mistakes. It covers SIM cards, bag drop rules, tap water, taxi vouchers, exit stamps, Sunday closures, and a few small items that make a real difference. Each section names a specific scenario so you can plan around it.

Your US Phone Dies at the Lima Airport SIM Kiosk

The SIM card kiosk in the arrivals hall is operated by a rotating set of Peru's three major carriers: Movistar, Claro, and Entel. All three sell prepaid SIMs with data plans aimed at tourists. But the kiosk closes at 8 PM on weekdays and is entirely closed on weekends. If your flight lands after that time on a Friday, you will not be able to buy a SIM until Monday morning. The small convenience store near the exit does not sell SIMs. The vending machines sell only snacks.

Even if the kiosk were open, your US phone might reject the local SIM. Most US carriers lock their phones to their network until the device is paid off or unlocked. AT&T, T-Mobile, and Verizon all have unlock policies, but they require a request that can take days. An unlocked phone is a prerequisite for any international trip where you plan to use a local SIM.

The airport's currency exchange booths are open later, but their spreads are notoriously bad—some estimates put the margin near 15 percent. You are better off withdrawing soles from an ATM at the airport, which gives a rate close to the interbank rate, though your home bank may charge a fee. But without a SIM, you cannot check your bank's exchange rate or confirm the ATM's fee. You are operating blind.

The bus to Miraflores, the main tourist district, costs roughly US$1.50 and runs until about 10 PM. But the bus stop is a short walk from the terminal, and without a SIM, you cannot use Google Maps to find it. You also cannot call an Uber, which requires data. The official taxi counter is your fallback, but it charges US$8–12 to central districts—a fair price, but only if you have cash in soles or dollars.

The solution is simple: buy a prepaid SIM online before you travel, or pick one up at a carrier store in the US that sells international SIMs. Alternatively, arrive during daytime hours on a weekday. If you must arrive late on a Friday, download offline maps and save your hotel address in a note. The kiosk's closure is a bureaucratic detail that becomes a major problem only if you ignore it.

The Bag Drop Clock That Punishes Early Arrivals

You arrive at the airport three and a half hours before your domestic flight to Cusco. The Latam counter is empty. You walk up, ready to check your bag. The agent tells you the counter opens exactly three hours before departure, not a minute earlier. You have to wait. This is not a policy unique to Lima, but it is enforced more strictly here than at many other airports. The reason is security: the airport limits the time bags sit unattended in the system.

The waiting area near the check-in counters has benches, but each bench has armrest dividers that prevent lying down. Sleeping on the floor attracts the attention of security patrols, who will ask you to move. The airport has a few lounges, but they require membership or a business-class ticket. For economy passengers, the three-hour rule means you should time your arrival to hit the counter exactly when it opens, not earlier.

For international departures, the rule is similar: counters typically open three hours before departure, sometimes four for certain destinations. But arriving earlier than that leaves you in a limbo zone with limited seating and no access to the airside shops and restaurants, which are past security. The airport's pre-security area is functional but not comfortable.

One more paperwork trap: visa-free travelers entering Peru are sometimes asked to show a printed exit ticket—a flight out of the country. This is not always checked, but it is a legal requirement for many nationalities. Without a printed copy, you may be denied boarding or held at immigration while they verify your plans. The airline counter will not print it for you. A phone screenshot is often accepted, but if your phone has no data, you cannot show it. A printed copy in your bag avoids this entirely.

The three-hour rule is a minor inconvenience if you know it. But if you arrive at 5 AM for a 10 AM flight expecting to check in early, you will spend two hours standing in a cold corridor. Plan your arrival accordingly.

Tap Water Warning: One Glass Costs You 48 Hours

Lima's tap water is treated and technically safe for locals, but visitors often react badly to it. The culprit is not bacteria but parasites—specifically, protozoa like Cryptosporidium and Giardia, which are resistant to chlorine. A single glass of tap water, even in a hotel that claims its water is filtered, may cause gastrointestinal distress that can last up to 48 hours, though individual reactions vary. This is a documented risk noted in travel health advisories from public health organizations.

Hotels typically provide one small bottle of water per person per day, usually 500 ml. That is enough for drinking but not for brushing teeth or making coffee. Many travelers use tap water for brushing without thinking, and that is enough to cause illness. The safe rule is to assume all tap water is not potable for your system, even if locals drink it.

Supermarkets in Lima sell 1.5-liter bottles for about US$0.60. The airport convenience store sells the same bottle for roughly US$3.00 after security, and up to US$5.00 in some shops. The price triples once you are past the checkpoint. Stock up at a supermarket before heading to the airport if you need water for the flight.

Refill stations are rare outside upscale malls and some Miraflores cafes. Carrying a reusable bottle with a built-in filter, such as those made by LifeStraw or Grayl, is a practical solution. These filters remove protozoa and bacteria, making tap water safe to drink. They cost about US$30–50 and pay for themselves in a few days of bottled water purchases. Without one, you are dependent on bottled water, which is widely available but adds cost and plastic waste.

The 48-hour illness risk is avoidable with simple precautions. Do not drink tap water, do not brush your teeth with it, and do not accept ice in drinks unless you are sure it is made from purified water. Most upscale restaurants use purified ice, but street stalls may not. When in doubt, skip the ice.

The Three-Copy Taxi Voucher You Must Sign

At the official airport taxi counter, you pay for a ride to your hotel and receive a multi-part receipt. The agent prints three copies: one for the driver, one for you, and one for the airport's records. You sign all three. The driver keeps one, you keep one, and the airport keeps one. This system is designed to prevent disputes and ensure accountability. It works, but it is slower than hailing a cab on the street.

Unofficial taxis wait just outside the terminal and offer rides for about 30 percent less. They are not insured for airport pickups, and there have been reports of overcharging and occasional theft. The official counter is the safer option, though it costs more. The fare range to central districts like Miraflores or Barranco is US$8–12, depending on the exact address and time of day. The ride takes about 40 minutes in moderate traffic, longer during peak hours.

If you use a ride-share app like Uber, you need data. Without a SIM, you cannot request a car. Even with data, the pickup point at the airport is not obvious. The designated ride-share area is a parking lot a short walk from the terminal, but the signs are small. Drivers often cancel because they cannot find you. The official taxi counter is the most reliable option for first-time visitors.

One more detail: the taxi driver may ask for your destination address in writing. This is standard, as many drivers are not familiar with every hotel. Have your hotel name and address written down or saved offline on your phone. The driver will appreciate it, and you will avoid the awkward back-and-forth of trying to explain directions in Spanish.

The voucher system is bureaucratic but functional. It ensures you pay a fixed price and have a record if something goes wrong. The unofficial taxis are cheaper but carry more risk. For most travelers, the official counter is the right choice, especially on a first visit.

Peru's Exit Stamp Hunt at Jorge Chávez

When you leave Peru, the departure tax is included in your airline ticket price since 2018. That change eliminated a common confusion. However, some airlines—particularly budget carriers—still ask for a cash receipt proving you paid the tax, even though it is included. This is a legacy of the old system, and not all check-in agents know the current rule. If you are asked for a receipt and cannot produce one, you may be sent to a separate counter to get a printed confirmation, which wastes time.

The immigration hall for departures has no printer for forms. If you need to fill out a paper form—which is rare now, as most airlines use digital forms—you must have it printed before arriving. The online form, known as the Andean Migration Card, must be filled out before you arrive at the airport. You receive a QR code that immigration scans. Without it, you may be delayed while they look up your details manually.

The exit stamp itself is a physical stamp in your passport, applied by immigration officers after they scan your QR code. The line can be long, especially during peak hours. Missing the stamp does not usually prevent boarding, but it can delay you until the last call while officers verify your departure. Allow at least 30 minutes for immigration formalities, even if you have no checked luggage.

One more nuance: if you are connecting through Lima to another country, you may not pass through immigration at all. In that case, you do not receive an exit stamp. This is normal, but it can confuse travelers who expect a stamp every time. For direct departures from Peru, the stamp is routine. Keep your boarding pass handy, as immigration officers sometimes ask to see it.

The exit process at Jorge Chávez is straightforward once you know the steps. Fill out the online form before arriving, have your passport and boarding pass ready, and do not worry about the departure tax. The stamp hunt is a minor hurdle, but one that catches unprepared travelers off guard.

Sunday Morning: The Lima Ghost Town Trap

Sunday morning in Lima is quiet. Most museums are open on Sunday, but they close on Monday instead. That is a common pattern in many cities. The trap is that banks, SIM card shops, and many small businesses are closed all day Sunday. If you arrive on a Sunday, you cannot buy a SIM, exchange currency at a bank, or visit a government office. The airport kiosk is closed, and the city's SIM retailers are closed too. You are effectively offline until Monday.

Miraflores Park is crowded by 10 AM with locals walking dogs, jogging, and families. It is pleasant, but the crowds mean that popular cafes and restaurants fill up quickly. The park has free Wi-Fi in some areas, but it is slow and unreliable. Without a SIM, you cannot easily find an alternative restaurant or check opening hours.

Pharmacies are open on Sunday, but they have limited selection. Sunscreen, for example, is hard to find outside of large supermarkets, which may also be closed. If you need toiletries or medication, buy them on Saturday or at the airport upon arrival. The airport's pharmacy is open daily and carries basic items, but prices are higher.

Uber supply drops by about 70 percent on Sunday before noon, according to anecdotal reports from drivers. Wait times can exceed 20 minutes, and surge pricing is common. The official taxi counter at the airport remains reliable, but within the city, you may struggle to find a ride. Buses run on a reduced schedule, and routes are harder to navigate without data.

The Sunday ghost town effect is predictable. If your itinerary includes a Sunday, plan all errands for Saturday. Buy your SIM, withdraw cash, and stock up on water and snacks before Sunday. The city is not dead—it is just running on a skeleton crew. With preparation, the quiet day can be enjoyable. Without it, you spend the day hunting for an open bank.

Three Small Items That Save Your Trip

An unlocked phone is the single most important item for any international traveler to Peru. Without it, you cannot use a local SIM, which means no data, no maps, no ride-share apps. Buy an unlocked phone before you travel, or request an unlock from your carrier at least a week in advance. Some carriers unlock automatically after the phone is paid off, but many require a manual request. Check your phone's settings under "Cellular" or "Network" to see if it is unlocked.

Printed copies of your hotel confirmation and flight itinerary serve as backup when your phone dies or has no signal. Immigration officers sometimes ask for proof of accommodation, and the airline may ask for an onward ticket. A single sheet of paper with these details solves the problem instantly. Keep it in your carry-on, not your checked bag.

US$20 in small sol bills—the Peruvian currency—is useful for airport snacks, bus fares, and tips. The airport ATMs dispense soles, but they sometimes run out of cash on weekends. Having a small amount of local currency on arrival means you can buy a bottle of water or a sandwich without relying on a credit card machine that may be offline.

A reusable water bottle with a built-in filter, as mentioned earlier, removes the parasite risk from tap water. It also saves money and reduces plastic waste. The initial cost is about US$30–50, but it pays for itself within a week of bottled water purchases. Look for models that filter protozoa and bacteria, not just taste.

A pen is a trivial item that becomes essential when filling out immigration forms on the plane or at the airport. The airline may hand you a form and expect you to fill it out immediately. Without a pen, you have to ask other passengers, who may not have one either. A simple ballpoint pen in your pocket solves this minor but annoying problem.

Before you leave, double-check your phone is unlocked and pack these items in your carry-on. They are the boring details that locals never explain because they do not think about them. But they are the difference between a smooth arrival and a stressful one.
