Plan your USA trip: tipping culture, transport realities, when to visit, traveler tips, and how to get affordable mobile data with an eSIM.
Secure, effective and private eSIMs across the globe
The United States is less a single destination than fifty of them: the skyline of New York, the national parks of Utah and Arizona, the music cities of Nashville and New Orleans, the Pacific Coast Highway and everything in between.
Distances are the thing first-time visitors underestimate. Flying between regions is normal, cities outside the Northeast are built around cars, and a two-week trip is better spent on one or two regions than on a coast-to-coast sprint.
Food is regional in a way first-timers underestimate. New England clam shacks, Texas barbecue, New Orleans po'boys, California produce, and diner coffee at 6am are different countries that happen to share a currency. Eat what the place is famous for and skip the national chains you already know.
Build the trip around one story: a national-park road trip, a city-and-coast pairing, or a music-and-food crawl. The USA rewards depth. The visitors who leave exhausted are usually the ones who treated it like a continent-sized scavenger hunt.

The price on the menu is not what you pay: sales tax is added at checkout and tipping 18-22% in restaurants is effectively mandatory. Mentally add about 30% to any restaurant price to avoid surprises.
The distances are enormous - Los Angeles to New York is like Lisbon to Moscow. Pick one region per trip. A week in the Southwest parks or in New England beats three days each in four time zones.
Popular parks like Yosemite, Zion and Glacier now use timed-entry reservations in peak season, and in-park lodges sell out close to a year ahead. Check recreation.gov as soon as your dates are set.
Ask for tap water and you get a full glass, then usually a refill, at no charge. Soft drinks work the same way. It is one of the few reliably generous things about American dining — use it.
New York, Chicago, Boston, DC and San Francisco have transit you can live on. Most other cities assume a car or a rideshare. Budget Uber as a line item, or rent a car the morning you leave the walkable core.

Yellowstone wants several nights, the Tetons want their own, and the Redwoods sit nowhere near Yosemite. Add a cushion to map times and pick one cluster instead of drawing a line across half the continent.

After an international flight, Global Entry is the US immigration lane that skips the long hall; TSA PreCheck is the domestic security line that comes with it. Put the Known Traveler Number on every airline booking or the perk never appears.

Since 2025, most cars pay a once-a-day congestion charge to enter Manhattan south of 60th Street. A tourist rental from Newark or JFK that you park under the hotel is how you buy a toll you did not budget. Use PATH, the subway, or a train into Penn or Grand Central and walk. The West Side Highway and FDR are the edge roads that stay outside the zone only if you never turn inland.

New York is retiring the MetroCard. Tap the same contactless bank card or wallet and the subway and local buses cap after a set spend in a rolling seven-day window that starts on your first tap — not a Monday-to-Sunday calendar. Two people sharing one phone at the gate breaks the cap. Express buses, group trips, and transfers do not count toward it. Commuter rail is a different ticket.

Almost certainly, if it is unlocked and supports eSIM - iPhone XS or newer, Pixel 3 or newer, or Galaxy S20 or newer. Modern phones handle the US LTE and 5G bands well, so an eSIM connects you to the same networks locals use.
More than in most countries: rideshares, mobile boarding passes, park reservations and navigation across big distances add up fast. Budget 2-3 GB per day, or pick an unlimited plan for road trips where your phone doubles as the car's navigator.
Coverage is strong in cities and along interstates but genuinely absent in large parts of parks like Yosemite, Zion and Glacier, and across remote desert stretches. Download offline maps before you drive in and treat in-park signal as a bonus, not a given.
US prepaid SIMs are surprisingly expensive and usually require a store visit with ID. A travel eSIM costs less, is set up before you land, and skips the retail detour entirely - useful when your first hours are spent clearing immigration and finding transport.
Most travel eSIM plans allow tethering, which is handy for hotel rooms with weak Wi-Fi and long train or car rides. Check the plan details before buying if hotspot use is important to you, as a few unlimited plans throttle it.
eSIM plans
With rideshares, mobile boarding passes and park reservation apps, the US assumes you are online at all times. An eSIM with a generous data allowance costs far less than international roaming and works the moment you clear immigration.
Park timed-entry, airline apps and turn-by-turn driving through a state you have never seen all assume a working connection. Roaming from overseas plans is brutal here. An eSIM is the cheaper, calmer way to land and just go.
