For data on a trip or business visit to the USA, the easiest and most economical approach is to set up an eSIM that works locally before you leave home. Bloomy eSIM makes it easy to keep the cost of a US plan down, and depending on the data amount it can work out cheaper than some major services (this isn't a claim to always be the lowest). Because pricing depends on the data amount, the number of days, and the exchange rate, please check the current figures on the US comparison page. Note that Bloomy is a data-only service.
"I want to use an eSIM in the USA, but I can't tell which one is cheap." "It's a short trip, so I'd like to keep connectivity costs as low as possible." If that sounds like you, this page covers how to read US eSIM pricing, a rough guide to how much data you'll need, how to choose, the setup steps, and what to do when you can't connect. Even if this is your first time using an eSIM, the goal is for you to finish reading knowing exactly which plan suits you. (Information is current as of June 2026. Prices and terms may change, so please check the latest details before you buy.)
Why an eSIM is affordable and hassle-free in the USA
An eSIM works by writing a plan onto a chip already built into your phone. There's no physical SIM card to swap in and out, and you can install it before you arrive in the USA. Since you don't have to hunt for Wi-Fi or a counter at the airport, or line up at a store once you land, setup is far lighter — even for first-timers or business trips with lots of connections.
On cost, the advantage is that you pick exactly the data amount and number of days you need. Unlike long-term contracts or roaming bundled with a new handset, you can buy only what fits your itinerary — "just five days in the USA," or "a bit more because I'll watch videos while sightseeing." That makes the USA a destination where it's relatively easy to keep connectivity costs down on short to medium trips.
Comparing prices for US eSIM plans
The table below shows the latest pricing for Bloomy eSIM's US plans (the price shown at the time you check is displayed automatically). Compare the data amounts and validity periods, and pick the one that fits your itinerary.

When you compare prices, checking these three points alongside the figure shown will help you avoid a poor choice.
| What to check | What to look for |
|---|---|
| Data amount (GB) | How much you need changes depending on whether you mainly use maps and messaging, or also social media and video |
| Validity (days) | It's reassuring to have a little more than your length of stay |
| Terms of use | Whether it's data-only, and for unlimited plans, whether speed limits or a fair-use policy apply |
Other providers' discounted prices shift over time, and exchange rates move the amount in your local currency too. So it helps to be aware of "when you saw a given price," and ultimately to compare each service on its own official, up-to-date listing. Bloomy focuses on making plans easy to find by data amount and days even for first-timers, and on supporting you with setup after purchase.
How much data you need for a US trip or business visit
If you're unsure how many GB you need, working backward from how you'll use it makes things clearer. These are rough guides only, but use them as a reference.
| How you'll use it | Rough data amount | Who it suits |
|---|---|---|
| Mainly maps, email, and looking things up | Around 3GB | A few days of business travel, light sightseeing |
| Frequent social media, photo sharing, and maps | Around 5GB | A typical short sightseeing trip |
| Also streaming video and using tethering | Around 10GB and up | Longer stays, or using several devices |
Watching video for long stretches or connecting a laptop to work uses a lot more data. If you're worried about running out, pick a slightly larger amount, or pair your eSIM with hotel or café Wi-Fi for peace of mind. If you want to use data freely on a long stay without watching the meter, an unlimited-type plan is also worth considering (even unlimited plans may have speed limits or a fair-use policy, so please check the terms in advance).
How to choose without going by price alone
Price matters, but "cheap" doesn't always mean "right for you." Thinking it through in this order helps you choose without waste.
- Days: Does the validity period cover your length of stay? Count layovers and any nights before and after, too.
- Data amount: Use the guide table above and work backward from how you'll use it.
- Standard data or unlimited: For longer stays where usage is hard to predict, unlimited is a candidate. For a short trip with a clear usage pattern, a standard amount is less likely to go to waste.
- Whether you need a number or SMS: If you need a US phone number or SMS verification, a data-only eSIM alone may not be enough (more on this in the next section).
Key things to know (about data-only service)
Bloomy eSIM is fundamentally a data-only service. App-based calls that run over data — WhatsApp, Messenger, FaceTime, and similar — work as usual. The only things you can't do are make and receive calls to/from a phone number (voice calls), and receive SMS sent to a phone number. It does not mean "no calling at all."
For most trips and business visits, messaging and app calls are enough to stay in touch, so data-only rarely feels limiting. That said, US banks, ride-hailing apps, and some services may ask for "SMS verification" to confirm your identity. If you need to receive an SMS sent to a phone number, consider pairing your eSIM with a number app (VoIP) that can receive SMS, or another option that includes a number. It's reassuring to check before you leave which services are likely to require a number or SMS.
The steps from purchase to using it on the ground
Here's the basic flow so it's clear even your first time. Activation timing can differ by plan, so always check the instructions provided at purchase.
- Check device compatibility: Confirm your phone supports eSIM with the compatible-device check.
- Install before you leave: While on Wi-Fi at home, add the eSIM following the instructions.
- Activate the line on arrival: After you reach the USA, turn on mobile data and configure roaming settings as instructed.
- Confirm the connection: Check that you can get online using a maps app or similar.
You can follow the detailed, screen-by-screen steps in the setup guide.
What to do if you can't connect in the USA
If you feel "stuck with no signal" or "can't get online" right after arriving, it's usually fixed by reviewing your settings. Don't panic — check the following.
- Airplane mode is off and mobile data is on
- The line you're using (the eSIM) is selected, and data roaming is set up as instructed
- The plan's activation time has arrived (some plans activate only after you reach your destination)
- Restart your phone once to let it reconnect to the network
If that still doesn't help, our connection troubleshooting page walks you through checks by symptom.

Summary
The USA is a destination where it's easy to keep connectivity costs down with an eSIM you choose by data amount and days. Start by estimating how much data you need from your itinerary, keep in mind that the service is data-only (calls and SMS to a phone number generally aren't available, but app calls like WhatsApp do work), and then check the latest pricing on the comparison page. If you finish installing before you leave, you can start using it simply by activating the line after you arrive. Prices and terms can change, so we recommend checking the latest details before you buy. Note that connection quality varies with the local network, your device, and the area.
