Cheap eSIM for United States: the real cost per day (and the cap trap to avoid)
Key facts
- A cheap eSIM for the United States starts at USD 15.90 for 5 days with VoaSim; the cheapest daily rate is USD 1.59 on the 60-day plan.
- Data is truly unlimited — no cap, no throttling, no fair use clause — so heavy Maps and video use never triggers a top-up.
- A second eSIM in the same order gets 10% extra off, which beats relying on tethering.
- Days start counting at the first connection in the US, so install the QR code at home and keep the line off until you land.
- Coverage runs on AT&T, T-Mobile and Verizon networks; expect gaps only in remote national park areas.

"Cheap" is easy to fake in the eSIM world. A 1 GB package looks like the bargain of the year until day two in New York, when Maps, Uber, Instagram Stories and a hotel video call have already eaten it. Then you top up. Then you top up again.
This page does the boring math instead: what a United States eSIM actually costs per day, why unlimited changes the equation, and when a small GB plan really is the smarter buy.
VoaSim price table for the United States

| 7 days | USD 20.90 | USD 2.99 |

Trips of 1 to 4 days pay the 5-day package. The maximum per eSIM is 90 days. There is no early-booking discount on this site, so buying three months ahead costs exactly the same as buying at the airport gate. Run your exact dates in the price simulator if you want the final number in one minute.
The cap trap: why GB plans get expensive in the US
A by-GB eSIM is priced on an assumption: that you will browse politely. American trips do not work that way. Maps running for a six-hour drive between Orlando and Miami, boarding passes, rideshare apps, video calls home across time zones, and the hotel Wi-Fi that makes you reach for mobile data instead.
What usually happens with a small package:
- You buy 3 GB because it was the cheapest line on the page.
- Day three, you get the 80% warning mid-navigation.
- You top up at a worse per-GB rate, or you start rationing.
With VoaSim there is no cap, no speed throttling and no hidden "fair use" clause. The advertised price is the price you pay for the whole trip. That is the part that makes a longer plan cheap in practice, not just on the label. See how we compare formats on the comparison page.
Two phones, two eSIMs: how the discount works
Traveling as a couple or a family? Add a second eSIM to the same order and it gets 10% extra off. Each phone connects on its own line, so nobody depends on someone else's hotspot.
That matters more than it sounds. Sharing your connection (hotspot or tethering) is not allowed: the local carrier may block your line. Each traveler uses their own eSIM, and 2 or more eSIMs get an extra 10% off. Two separate eSIMs is the safe, predictable setup.
Practical split for a 10-day US trip: two lines at USD 29.90 each, minus 10% on the second one. Both people have Maps, both have Uber, both have Instagram, and neither is stuck waiting for the other to wake up their phone. Compare durations side by side on the best plans guide.
Today's prices
Today's promo prices (15% off). Each destination has its own price. 2 to 4 eSIMs in the same order: 10% extra off. Trips of 1-4 days use the 5-day package.
Coverage in the United States: what you actually get
The eSIM connects automatically to local networks — AT&T, T-Mobile and Verizon — without you choosing anything. In New York, Orlando, Miami, Los Angeles, Las Vegas and San Francisco, coverage is dense and 5G is widely deployed, though we never promise 5G because it depends on your phone and the tower you are on.
Where to expect gaps: remote stretches of national parks. Parts of Death Valley, corners of Yellowstone, desert highways between Las Vegas and Utah. No carrier, local or roaming, covers every mile of that. Download offline maps before you drive out.
One more limit worth knowing: on a cruise the eSIM works on land at ports, not at sea. And the island Caribbean is not covered right now, though Puerto Rico works because it runs on US networks. Full details on the destinations page.
Cheap eSIM vs carrier roaming vs local SIM
| VoaSim eSIM | Carrier roaming | Local US SIM | |
|---|---|---|---|
| Price | Fixed table, from USD 1.59/day | Per day of use or bundled — check your carrier app | Varies by store and plan |
| Data | Unlimited, no throttling | Daily allowance, often slower after it | Usually capped |
| Your number | Stays active on your physical SIM | Stays active | SIM comes out of the phone |
| Setup | QR by email, install at home | Enable before you fly | Shop time after landing |
Be fair about it: if you only need messages and a couple of maps over a weekend, your carrier's day pass or a small GB plan may be cheaper. If you are online all day for a week or more, the fixed unlimited price wins. Our roaming explainer goes deeper.
Buying and installing without wasting a day
You pay by international credit or debit card in USD through Stripe. No hidden fees, invoice by email. There is no cash option and no local-currency billing.
The QR code arrives by email within minutes. Install it at home, before the flight — and leave the eSIM line switched off until you land. Your days only start counting at the first connection to a network in the United States, so installing early costs you nothing. On Android, do not turn on the eSIM's data before the trip.
Check compatibility first: iPhone XR or newer, Galaxy S20 or newer, Pixel 3 or newer, and most phones from 2020 on. Dial *#06#; if an EID appears, you are fine. Carrier-locked phones need unlocking. If any eSIM of any brand refuses to connect, the free eSIM Rescue tool diagnoses it, and if our support cannot fix ours, you get a 100% refund. More on that in how we work.
Why trust VoaSim?
Registered company with an invoice on every purchase, USD payment via Stripe with no hidden fees, 24/7 human support and a guarantee: if the eSIM will not connect and support cannot fix it, you get 100% back.
