Travellers from countries participating in the Visa Waiver Program may be able to visit the United States for tourism or business for up to 90 days without obtaining a traditional visa, but an approved ESTA is required before travelling. Eligibility depends on nationality and individual circumstances. Always check the latest requirements on the official U.S. government website before departure.

International roaming from your home mobile provider can be convenient, but it may also be expensive. A USA travel eSIM allows compatible unlocked smartphones to connect to a supported American mobile network without replacing the physical SIM card. This makes an eSIM particularly convenient for navigation, messaging, social media, bookings and everyday internet use during your trip.

For travellers who expect to use a lot of mobile data, our 30-day USA eSIM provides unlimited high-speed data on the T-Mobile 5G network together with unlimited talk and text. A U.S. phone number is generated within approximately 30 minutes and hotspot functionality is supported.

Yes. This USA eSIM includes a U.S. phone number that is normally generated within approximately 30 minutes. This can be useful when travelling because some hotels, restaurants, services and local contacts may ask for a U.S. telephone number.

Yes. Hotspot support allows you to share the mobile connection from your phone with another compatible device such as a laptop or tablet. This can be particularly useful for business travellers, remote workers and travellers who need internet access on several devices.

The United States has several major mobile networks, including T-Mobile, AT&T and Verizon. Network coverage and speed can vary significantly depending on location. Large cities generally have extensive 4G and 5G coverage, while remote areas, national parks, mountains and long stretches of highway may have weaker or unavailable mobile service.

Foreign visitors can generally drive in the United States with the appropriate licence, but requirements differ between states. Some states or rental companies may require an International Driving Permit in addition to your national driving licence. Check the requirements for every state you plan to visit before travelling.

Tipping is an important part of service culture in the United States. At sit-down restaurants, travellers will commonly encounter tipping expectations of around 18–20 percent, while suggested tip options may also appear on payment terminals in bars, taxis and other service businesses. Always check whether a gratuity has already been added to the bill.

Credit and debit cards are widely accepted throughout the United States, including in hotels, restaurants, shops and many transport services. Contactless payments and mobile wallets are increasingly common. Carrying a small amount of cash can still be useful for tips, small businesses, parking or situations where cards are not accepted.

The United States commonly uses Type A and Type B electrical plugs and approximately 120-volt electricity. Travellers from Europe and many other regions will normally need a plug adapter. Check whether your phone, laptop and other chargers support the local voltage before connecting them.

The United States spans multiple time zones, which can become important when taking domestic flights or planning a long road trip. New York and Los Angeles, for example, are several hours apart. Always check local time when booking flights, tours, transfers and online meetings.

For a shorter city break, New York is one of the easiest introductions to the United States. Florida combines beaches, Miami and Orlando attractions, while California is ideal for travellers who want to combine major cities with a road trip. The best destination depends on the season, length of your trip and whether you prefer cities, beaches, entertainment or nature.

Data usage depends heavily on how you travel. Maps and messaging use relatively little data, while social media, video streaming, video calls, cloud backups and hotspot usage consume much more. Travellers who rely heavily on their phone throughout the day may prefer an unlimited plan instead of continuously monitoring a fixed data allowance.

You can prepare your eSIM before travelling so that your phone is ready for the United States. For this particular 30-day unlimited USA plan, remember that validity starts from the date of purchase. The U.S. phone number is normally generated within approximately 30 minutes after purchase.
