Best eSIM for United States in 2026: unlimited data, real prices and what to check
Key facts
- VoaSim's US eSIM is unlimited data with no cap and no throttling, from USD 18.90 for 5 days to USD 61.90 for 30 days.
- One flat price per duration applies to every destination, including all US cities; 1-4 day trips pay the 5-day package.
- The eSIM attaches automatically to AT&T, T-Mobile or Verizon networks; remote national park areas may have no signal on any carrier.
- Your days start at the first connection in the US, so install at home and keep the eSIM line off until you land.
- Very light users or stays over 90 days are usually better served by a per-GB pack or a local US prepaid line.
See the exact price for your dates
Picking an eSIM for a US trip is mostly a math question. If you stream maps all day, rideshare between neighborhoods and post video from Times Square or the Vegas Strip, a plan sold by the gigabyte gets expensive fast. If you barely leave hotel Wi-Fi, a small data pack may be enough.
This page lays out both sides: what VoaSim costs for the United States, which networks you actually land on, how per-GB brands work, and the cases where another option beats us. Then you can run your dates in the simulator and decide in a minute.
VoaSim prices for the United States (one price, any destination)
VoaSim charges by trip length, not by country and not by gigabyte. The same table applies to New York, Orlando, Miami, Los Angeles, Las Vegas or San Francisco. Today's prices already include the 15% promo:
| Duration | Price | Per day |
|---|---|---|
| 5 days | USD 18.90 | USD 3.78 |
| 7 days | USD 23.90 | USD 3.41 |
| 10 days | USD 30.90 | USD 3.09 |
| 15 days | USD 42.90 | USD 2.86 |
| 30 days | USD 61.90 | USD 2.06 |
| 60 days | USD 106.90 | USD 1.78 |
Trips of 1 to 4 days pay the 5-day package. The maximum is 90 days per eSIM. Adding a second eSIM to the same order (for a partner or a second phone) takes 10% extra off that line. Payment is by international credit or debit card in USD through Stripe, with an invoice by email and no hidden fees. Check your exact total in the price simulator.
Which networks you get in the US and where signal can drop
The eSIM does not belong to one single US carrier. Once you land, the phone searches for partner networks and attaches automatically — in practice that means AT&T, T-Mobile or Verizon, depending on where you are standing. You do not pick the network manually in normal use.
Coverage is strong across the big metros and the tourist corridors: Manhattan and Brooklyn, the Orlando theme park area, South Beach, downtown LA, the Strip, the Bay Area. 4G is the baseline and 5G appears where the local network offers it, so treat fast speeds as a bonus rather than a promise.
The realistic gap is remote terrain. In parts of national parks — canyon floors, backcountry roads, long desert stretches — no carrier has usable signal, and no eSIM changes that. Download offline maps before a Utah or Arizona road trip. In cities, the practical difference between brands is small; what changes your bill is how data is sold.
Unlimited vs per-GB: how to choose for a US trip
Two models dominate the market. VoaSim is flat and unlimited: you pay for days, not volume, with no cap, no throttle and no quiet "fair use" clause. Brands like Airalo, Nomad, Saily, Ubigi, Jetpac or GigSky typically sell buckets of gigabytes valid for a set number of days, bought inside their apps. Holafly sells unlimited-style plans with usage conditions written into its terms.
| Your trip | Better fit |
|---|---|
| Maps, rideshare, streaming, video calls, hotspot-free heavy use | Unlimited by day |
| Mostly hotel Wi-Fi, a few messages a day | A small per-GB pack |
| Two weeks with family, one phone navigating for everyone | Unlimited by day |
| Six months living in the US | Local US plan or postpaid line |
Prices and caps change often on every app, so compare the current terms yourself before buying. Our full comparison page and the best-eSIM guides go deeper.

When a local SIM or carrier roaming is the smarter call
We would rather you buy the right thing than the wrong thing from us.
- Very long stays. Beyond 90 days, a VoaSim eSIM no longer fits — the cap is 90 days per eSIM. A US prepaid line is the sane option, and it gives you a US phone number, which matters for deliveries, banks and some apps.
- You need a US number. VoaSim is data only. WhatsApp, FaceTime, Telegram and app calls work over data on your existing number, but you do not get a new number or traditional voice minutes.
- Very light users. If you check messages twice a day, a small gigabyte pack from a per-GB brand can come out cheaper than any daily rate.
- Short hops on a bundled plan. If your home carrier already includes US roaming in your plan, use it. If it bills per day of use with a small allowance and reduced speeds afterwards, check the current rate in your carrier app and compare. See our roaming notes.
Install before you fly: the exact sequence
Buy, then install at home. The QR code lands in your email within minutes (plus a WhatsApp heads-up if you left a number at checkout), and the guide walks through iPhone and Android screens.
- Check the phone. iPhone XR or newer, Galaxy S20 or newer, Pixel 3 or newer, and most phones from 2020 on. Universal test: dial *#06# — if an EID appears, you have eSIM. A carrier-locked phone must be unlocked first.
- Scan the QR at home, on Wi-Fi, days before the flight. Installation is not activation.
- Keep the eSIM line off until you land. Days start counting at the first connection to a network in the US. On Android, do not switch the eSIM's data on before the trip.
- On arrival, enable the eSIM line, set it as the data line, and turn off data roaming on your home carrier so nothing bills you twice.
Your physical SIM stays in the phone, so your number and WhatsApp keep working. Landing at JFK, MCO or LAX? See the airport arrival tips.
If it does not connect
Most no-signal cases are settings, not hardware: the eSIM line is off, the data line is still the home SIM, or airplane mode never came off after the flight. Our free eSIM Rescue tool walks through the diagnosis step by step and works for an eSIM of any brand, not only ours.
If that does not solve it, write to hola@voasim.com or use the on-site chat — a human answers. And the backstop is simple: if the eSIM will not connect and support cannot fix it, you get a 100% refund. More on how we operate is on the trust page.
Two limits worth knowing before you travel. Cruises: the eSIM works on land at ports, not at sea, so budget for the ship's own package if you need to be online between stops. Hotspot: do not plan around it — it depends on the plan, so confirm with support before you rely on tethering a laptop or a second phone.
Why trust VoaSim?
Registered company with an invoice on every purchase, USD payment via Stripe with no hidden fees, human support and a guarantee: if the eSIM will not connect and support cannot fix it, you get 100% back.
