How to get mobile internet in the USA: A tourist’s guide for 2026

Is mobile internet good in the USA? What tourists can expect

Most major cities and urban areas in the US — such as New York, LA, Chicago, and Miami — have strong 4G and 5G coverage. Where 5G isn’t available, your phone may fall back to 4G LTE. Both are fast enough for Google Maps, ride-sharing apps, streaming, and video calls through apps like FaceTime and WhatsApp. However, coverage isn’t always perfect outside urban areas. For example, remote highways, national parks, deserts, and mountainous areas such as parts of Yellowstone, Zion National Park, and the Grand Canyon may have weak or no signal at all. Your experience will also depend on which US network your home carrier or travel eSIM provider uses.

The three major networks in the US are T-Mobile, Verizon, and AT&T. The table below compares their main strengths and the types of trips they may suit best.

If you’re using a travel eSIM, you don’t need to pick a carrier — most eSIM providers have agreements with one or more networks in the US. Those planning to use an eSIM in the USA should check which network their plan uses and the coverage it includes.

Best ways to get mobile internet in the USA 

From eSIMs to pocket Wi-Fi devices, tourists who want to use their phones in the US while reducing or avoiding roaming charges have many options. Each has its pros and cons, and the best for you will depend on how long you’ll stay, where you’ll go, and how much you’d like to spend. Below is a list of options to help you compare and contrast.

1. Use an eSIM — fast and flexible

An eSIM is a digital SIM card that you install through an app before or during your trip. You won’t need to hunt down a place that sells physical SIM cards, and you won’t be required to have a US-based address or Social Security number. 

On a compatible dual-SIM phone, you can use the eSIM for data while keeping your home number available for calls and two-factor authentication texts. Many recent iPhones and Android flagship models are eSIM compatible. That said, check your carrier’s roaming charges before answering calls or sending messages through your home line.

An eSIM has many benefits, especially for itineraries containing multiple destinations, because you can manage several destination plans from one app without collecting or swapping physical SIM cards. Saily offers several affordable eSIM plans for the US, with unlimited hotspot capability. Saily also covers 200+ destinations worldwide, so the same app can be used on other trips too.

Developed by Nord Security — the company behind NordVPN — Saily also features built-in web protection and an ad blocker. Because an eSIM is built into the device rather than stored on a removable card, it can’t be lost, damaged, or removed the way a physical SIM card can.

2. Buy a local prepaid SIM card — perfect for long stays

When comparing SIM cards vs. eSIMs, it helps to consider whether your device is compatible, what your itinerary looks like, how long you’ll be traveling, and how much you’d like to spend. Local US prepaid SIM cards may be a good option for those planning on staying for a while because they typically offer lower long-term costs and reliable coverage. A local prepaid plan may also provide a US phone number, which can be useful during a longer stay. However, installing a physical SIM may mean removing your home SIM unless your phone supports two active SIMs.

T-Mobile, AT&T, Verizon, and prepaid brands like Mint Mobile, US Mobile, and Straight Talk offer local, prepaid physical SIM cards for purchase in airports, carrier stores, and big-box retail stores such as Best Buy, Target, and Walmart. 

No single US network will be the best for every tourist. T-Mobile generally performs well for city trips and widespread 5G access. Verizon is often favored for reliability and LTE fallback, while AT&T offers broad, balanced coverage across many urban and regional itineraries. Always compare coverage for the specific places you plan to visit.

Prepaid plans commonly cost around US$30-70 per month, depending on the carrier, data allowance, hotspot access, and available discounts. Unlimited plans from the three major carriers often begin at approximately US$35-60 per month before taxes and fees.

Travelers visiting major cities can also compare options for a New York SIM card or a Miami SIM card.

Good to know: Tourists can generally buy prepaid service without a US Social Security number or credit check. However, identification, billing address, payment-card, and activation requirements typically vary by carrier and retailer, so check the provider’s terms before purchasing.

3. Use roaming — convenient for very short trips

If you’re only in the States for a short trip, using your home carrier for roaming in the US might be a good option, but it does have its drawbacks. For example, European visitors may encounter surprise charges because the US doesn’t have the same “Roam like at home” regulations as countries in the European Union do. “Roam like at home” regulations ban mobile network operators from charging an extra cost for calling, texting, or using mobile data while traveling only within the European Union. 

Pay-as-you-go services can be convenient, but costs add up fast — and you may still be in for a shock when you open your phone bill if you’re not monitoring your data usage closely. Many carriers also offer day pass-style roaming plans, typically from US$5-15 per day on average, depending on your carrier and how much data you purchase. 

Pay-as-you-go roaming can become expensive quickly because maps, social media, app updates, and photo uploads consume data in the background. A day pass or prepaid USA travel eSIM usually makes the cost easier to predict.

The price difference in data roaming options becomes clear when comparing a roaming pass with a dedicated travel eSIM. For example, if your carrier charges US$10 per day for international roaming, you would spend US$70 during a one-week trip. Saily’s US eSIM plans start at US$3.99, so even a larger prepaid data plan may cost considerably less than using a roaming pass every day.

4. Rent pocket Wi-Fi — best for groups or families

A pocket Wi-Fi device is a portable hotspot that travelers can rent from international connectivity providers and have delivered to a home or hotel or buy as a prepaid mobile hotspot from a US carrier or electronics retailer. Some providers offer airport pickup, but it isn’t offered at every US airport. 

The best portable Wi-Fi for travel will likely depend on trip length and how many people will need to use it. A pocket Wi-Fi might be a good option for groups or families because it’s shareable across multiple devices and travelers without SIM swapping. On the other hand, you will need to keep up with it as you travel, keep it charged, and deal with the logistics of where and how to return it so you can get your deposit back.

Pocket Wi-Fi often begins around US$5-10 per day, although device fees, data limits, shipping, and deposits can increase the total. For solo travelers or couples, an eSIM is usually a simpler and cheaper option.

5. Connect to public Wi-Fi

Public Wi-Fi is widely available in US hotels, cafes like Starbucks, restaurants, malls, and airports. However, it’s usually best used as a backup rather than a primary connectivity strategy because it can be slow, and you may not get access everywhere. Some locations require registration and may limit your time online. 

Additionally, public Wi-Fi isn’t always safe. Open networks may be poorly secured or can be impersonated by shady hotspots. Avoid entering sensitive information unless necessary, confirm the network name with the venue, and keep file sharing switched off. Using a VPN (virtual private network) on public Wi-Fi is highly recommended. VPNs such as NordVPN establish a secure, encrypted “tunnel” between your device and the internet. Saily eSIMs also offer web protection, an ad blocker, and a virtual location changer.

How much data do you need for your trip to the USA?

Most travelers need between 3 GB and 15 GB of data for a 1-2 week trip to the US, but this depends on how much you rely on public Wi-Fi versus cell networks and what you use your phone for. For example, a 5 GB plan may last several weeks for a traveler who mainly uses maps and messaging, connects to Wi-Fi regularly, and avoids video streaming, automatic backups, and large downloads using mobile data, but it may not last so long for those who need to work remotely.

As a rule of thumb, travelers who mainly use data for navigation, messaging, email, and light social media may need roughly 1-3 GB per week if they also connect to public or hotel Wi-Fi.

People who browse social media more often, upload photos, use rideshare apps, and check out restaurant reviews on the go might expect to use about 3 GB to 7 GB per week with minimal video streaming or downloading. Heavier users who need to work remotely, stream videos, make FaceTime or WhatsApp video calls, and tether or hotspot other devices may use 10+ GB per week.

How to use your phone in the USA

Most recent, unlocked smartphones work in the USA, but you should make sure your device supports the 4G LTE or 5G bands used by your network. You can check compatibility through your home carrier’s website, app, or direct customer service line. 

Additionally, the major US carriers have retired their 3G networks, so verify that your phone supports Voice over LTE (VoLTE) to make standard voice calls in the US. Using WhatsApp, FaceTime, Zoom, or another internet-calling app over mobile data or trusted Wi-Fi is usually the cheapest way to call home.

Next, decide whether you’ll use international roaming through your carrier, an eSIM, a prepaid physical SIM card, or a pocket Wi-Fi device. Travelers who want to avoid home-carrier charges altogether can also review the different ways to use a phone overseas without roaming.

Follow the activation instructions provided by your chosen carrier or eSIM app. A travel eSIM may require data roaming to be enabled on the eSIM line, while travelers using their home carrier should only enable roaming after confirming that their mobile plan covers US usage. If you use public Wi-Fi, make sure to use a VPN to protect your personal data and passwords from security risks.

💡Pro tip: If you have a dual-SIM compatible device, keep your home SIM active for SMS messaging and two-factor authentication while using the eSIM for data. Check your carrier’s terms and disable data switching to guard against surprise roaming charges.  

What’s the best option for you?

For most tourists, a travel eSIM offers the best combination of price, convenience, and flexibility. You can install it before departure, connect shortly after arrival, keep your physical SIM in your phone, and choose a data allowance that matches the length of your trip. Saily offers flexible US data plans starting at US$3.99, unlimited hotspot sharing, access to reliable local networks, and built-in security features.

A local prepaid SIM may offer better long-term value if you are staying for several weeks or need a local phone number. Pocket Wi-Fi can make sense for families and groups sharing one connection for several devices, while international roaming is most convenient for very short trips when your home carrier includes an affordable US pass. Public Wi-Fi is free and widely available, but it is better used as an occasional backup than as your only way to get online. 

Travelers can also choose destination-specific plans, including a New York eSIM, Los Angeles eSIM, or Hawaii eSIM. Before traveling, compare the available eSIM plans for the USA or download the Saily eSIM app to set up your connection.
