We looked for proper coverage, affordable prices, plans with unlimited data, user-friendly applications, and reliable customer support. Ultimately, we settled for the five you see below. If you want to find out more, read our comprehensive reviews of the best eSIM providers for the USA in 2026, with their pros and cons.

Best eSIM for the USA: Detailed List

Let’s get down to business and review our top five. Apart from their extensive coverage in the US, they’re also good eSIMs for international travel. However, we’ll focus on its USA plans, their features, pros, cons, and prices.

1. Ubigi

Ubigi has the most diverse eSIM plans for the United States. You can pay monthly, annually, or get an one-fof plan. Data ranges from 500 MB to unlimited, with fairly affordable prices. For example, 500 MB costs only $2.90 for a day. However, you can get unlimited data for as little as seven days for $25.

Ubigi’s prices are lower for lengthier plans. Thus, unlimited data for a month is $65, making it one of the least expensive options. Ubigi offers impressive coverage, with reliable 4G and 5G connections for fast speeds. Additionally, it has beginner-friendly apps for Android and iOS, which you can use to set up your eSIM.

The best eSIM for the USA offers a few advanced features. For example, you can share data with your other devices or friends while in the USA. The provider also covers 200+ countries around the globe, so it’s easy to find an eSIM for your next travel destination. One thing we dislike is the lack of a phone number.

This means neither of the plans allows phone calls or SMS. However, calls and SMS aren’t so convenient compared to VoIP services and their intuitive apps. In practice, Ubigi works well, with impressive coverage, stable speeds, and high-bandwidth connections. You’ll enjoy all activities, including video-calling, gaming, and streaming.

2. Saily

Saily is the best eSIM for the USA for privacy and security. Its Ultra plan even includes a free month of NordVPN. Even with a standard plan, it blocks ads and offers a virtual location. The provider offers 1 GB to unlimited plans for a fair price. 1 GB of data is $3.99 for seven days, but our favorite is 10 GB for 30 days at $22.99.

Unlimited data eSIM plans for the USA are available, and start at $18.99 for five days. For 30 days, you’ll spend $71.99 (more than Ubigi, our #1). Saily’s coverage was exemplary in our tests, with 4G/5G networks for superb streaming, gaming, and social media experiences. We also tested VoIP video calling with stellar results.

It’s worth noting that Saily doesn’t cover Alaska; neither does Ubigi. If you’re not going to Alaska, either way, that won’t matter. What matters is Saily’s overall quality, security, low prices, and 24/7 support. Keep in mind, Saily doesn’t offer a phone number, so forget about SMS and calling in the USA or abroad.

3. Holafly

Holafly is the best eSIM for the USA for unlimited data and all-around coverage. The pricing structure is simple: $3.90 per day of unlimited data. However, you can pay for three, five, or more days, up to 30. The 30-day unlimited data eSIM for the USA is $74.90, more than Saily or Ubigi; that’s why Holafly is #3.

Luckily, it’s worth the extra. Holafly’s coverage means no roaming charges in any state. Plus, it relies on AT&T networks to provide 4G LTE and 5G connections. During our trip to the US, we had zero issues with VoIP calls, online gaming, or using streaming apps. However, we noticed that Baja California isn’t covered.

Unlike Ubigi and Saily, Holafly covers Alaska. Another curiosity is that Holafly’s US eSIM plans have unlimited data by default; you can’t go lower. That’s useful because it allows easy data sharing, although up to 500 MB. Holafly’s 24/7 support is exemplary, while its apps on iOS and Android offer a seamless setup.

4. Airalo

Airalo has fairly inexpensive eSIM bundles for the USA. If you need only the US, you can get Standard or Unlimited plans. We advise the latter if you’re staying for long, because the price of $61.50 for 30 days is one of the lowest on this list. Meanwhile, if you’re there briefly, you can opt for 1 GB to 50 GB of data.

Another worthy option is the North America package, which covers Mexico and Canada, but doesn’t offer unlimited data. Either way, Airalo performs well, with extensive coverage that includes Alaska and Puerto Rico, and teams up with Verizon, U.S. Cellular, and T-Mobile for good stability and 4G/5G speeds.

Airal’s activation is pretty simple and is facilitated through its free app on Android and iOS. If you can’t find your way around it, 24/7 live chat support is also available. Airalo offers some plans with SMS and calling, but sadly, they’re expensive and don’t offer much. You also can’t pay as you go, which hurts its flexibility.

5. Nomad

Nomad is a free eSIM for the US with 1 GB of data for three days. That’s a small offer, but a good chance to test it. If you need more, and you likely do, the best option is 20 GB or 50 GB for 30 days for $18 and $27, respectively. Nomad even offers unlimited data, but sadly, only for 20 days, for a price of $49.

While not the cheapest, Nomad has some of the fastest connections we experienced, with reliable connectivity in Los Angeles, New York, and other large cities. 5G is supported in all US plans, and Nomad cooperates with AT&T and T-Mobile to solidify its performance and offer reliable coverage at all times.

Noteworthy is the North America eSIM package, which starts at $8 for 1 GB of data for only seven days. Again, not the cheapest. Nomad has decent customer support via live chat, the activation process is easy through the app, and there are business extras like employee onboarding and real-time data usage monitoring.

How to Choose the Best eSIM for the US?

Unsure which one to pick? Need additional help? Here’s what to consider before buying the best eSIM for the US in 2026.

• Coverage. Get an eSIM with the best possible US coverage, and if needed, opt for the regional North America plan if you visit Canada or Mexico. Such plans also tend to cover Alaska, if needed.
• Sufficient data. Heavy internet users need more data, and vice versa. Examine your data consumption at home and anticipate how much data you’ll need in the USA. Browsing consumes less, while streaming and gaming consume more data.
• Connection speed. Look for US eSIM providers with at least 4G LTE and 5G coverage in as many states as possible. 5G is always preferred for speed and low latency, but even 4G LTE is speedy enough.
• Trip length. Pick the plan that best suits your trip duration. While monthly packages are the cheapest, you don’t have to pick one if you’re there for a week.
• Value for money. It’s not always about the lowest price. It’s about what you get for the money. Review your options and pick the one that best fits your budget and satisfies all your demands.

Summary

With these eSIM providers and their versatile plans, a trip to the USA isn’t so frightening. It takes a few minutes to subscribe to the best eSIM for the USA, get unlimited data, and enjoy excellent coverage to stay online at all times. Bear in mind, these are some of the best eSIMs overall, so they’re usable worldwide.

While Ubigi is our top choice, other options are worth exploring. Saily offers unique security features, Holafly has fast 5G speeds, Airalo has unlimited data plans, and Nomad even lets you test it for free for three days. In any case, don’t forget to activate your eSIM on time to immediately enjoy it once you land on US soil.
