United States eSIM with Calls & Phone Number
USA eSIM with a real US phone number (+1): unlimited AT&T 5G data, unlimited US calls & texts, plus calls to 100+ countries. SMS codes arrive right on your phone to register WhatsApp & any app — no extra app needed. Instant QR setup, no contract.
Validity starts at purchase. Install once — please don't delete it. 50GB high-speed, then throttled to 512 kbps.
Your Selection
Your plan only starts counting when the eSIM first connects at your destination — so you can buy today and travel in three weeks.
How does Simbye eSIM work for the USA?
Get connected in under 2 minutes
Set it up at home
An email with a link and a QR code arrives the moment you buy. Set the eSIM up at home on WiFi, it takes two minutes. Your normal plan stays untouched in the phone.
Switch it on after landing
Whether you arrive at JFK or Newark in New York, in Los Angeles, Miami, Chicago O'Hare, San Francisco, Orlando or Las Vegas: turn off airplane mode, turn on data roaming for the new line — you are online after a minute or two. Only now does your plan start counting down.
Use your US number
Your +1 number is ready for calls and texts straight away. Enter it wherever a phone number is asked for: rental car, Uber, restaurant waitlist, verification codes. Your number from home can stay in the phone alongside it, so people can still reach you there.
Which networks will you be on in the USA?
Your phone connects to AT&T on its own — there is nothing for you to set up.
Half of all mobile speed tests in the country come out above this, half below. Speedtest Global Index, July 2026. There are no separate figures per network for this country.
The eSIM runs on AT&T. As soon as you land in the USA and switch off airplane mode, your phone finds the network by itself; you do not have to pick a network or type anything in. The only thing that matters is that data roaming is switched on for the new line — that is normal for an eSIM bought abroad and costs nothing extra. If there is still no signal after a few minutes, switching airplane mode on and off once almost always does the trick.
AT&T is one of the three nationwide networks in the USA. In New York, Los Angeles, Chicago, Houston, Miami, San Francisco, Boston and Seattle you will usually be on 5G, with solid LTE in the suburbs and along the big interstates, and reception is a non-issue in Las Vegas, Orlando, New Orleans and San Diego too. It gets thin where almost nobody lives: Death Valley, large parts of Yellowstone and Yosemite, the canyon country around Zion and Bryce, the desert between Las Vegas and California, and the Rockies. That applies to every US network, not just AT&T — if you are planning a road trip through the national parks, download your maps for offline use before you go.
How much data do you need in the USA?
So you can work it out instead of guessing: how much an hour costs in the apps you actually use on holiday.
The Netflix and Spotify figures come from the providers themselves (Netflix Help Center, Spotify Support, retrieved 28 Aug 2026). The rest are network-operator estimates (o2, Vodafone, EE) and vary with picture quality and reception.
This eSIM only starts once you are in the USA
You can install it calmly at home on WiFi, but it will not connect to a network until you have landed in the USA. Before that your phone simply shows no service for this line — that is not a fault, it is how it is meant to work. The upside: your days only start counting once you are actually there. It does not work outside the USA, and that includes Canada and Mexico.
Two things are worth checking on your phone beforehand. It has to support eSIM and must not be locked to a single carrier. And for calls it needs calling over LTE, because AT&T has switched off its old 3G network — without that feature data still arrives, but calls do not. On current iPhones and most Android phones both have long been standard.

eSIM or a local SIM card in the USA?
| Compared | Simbye eSIM | Local SIM card |
|---|---|---|
| When you get it | By email the moment you buy, installed before you fly | Only after you land: find a store, queue, fill in a form |
| Phone number | A US number with +1 is included | Also available, but it takes time at the counter |
| ID and registration | Not needed | There is no registration requirement in the USA, but a carrier store will often still ask for your passport |
| Price | Fixed in advance and paid at home | Airport kiosks are usually pricier than stores in town |
| Paying | Your card in the online shop, final price included | Card or cash on the spot, and sales tax is added to the shelf price at the register |
| Your number from home | Stays in the phone, people can still reach you | Has to come out on single-slot phones |
| Language | Bought and explained in your own language | Advice in English, jargon included |
| If something goes wrong | Support by email, a fresh QR code | Back to the store, often far from your hotel |
Why your home plan gets expensive in the USA
The EU roaming rule that protects you in Spain or Italy stops at the EU border. The USA is not an EU country — your provider's international rates apply there, and that is a completely different price list from your domestic allowance.
How expensive it gets depends on your contract. Some providers sell day passes, others charge by the megabyte, others again bundle the USA into an add-on. Check your plan overview before you fly and look for USA or worldwide — that is where the number that applies to you is written down. We deliberately quote no prices here, because they differ from contract to contract.
The second point is easy to miss: even with an expensive international package you still have your European number in the phone. American services that ask for a phone number often cannot handle it, and every incoming text and call still runs through your international rate. That is exactly what a US number of your own is for.
Where the network reaches — and where it does not
AT&T is one of the three nationwide networks. In the big cities — New York, Los Angeles, Chicago, Houston, Miami, San Francisco, Boston, Seattle, Washington — you will usually be on 5G, with solid LTE in the suburbs and along the major interstates. Reception is a non-issue in Las Vegas, Orlando, New Orleans and San Diego too.
It looks different where almost nobody lives. In Death Valley, across large parts of Yellowstone and Yosemite, in the canyons around Zion and Bryce, in the desert between Las Vegas and Los Angeles and high up in the Rockies there are long stretches with no signal at all. That is not a shortcoming of this eSIM — it applies to every American network equally.
In practice: if you are planning a road trip through the national parks, download the route as an offline map beforehand and send the message home from the last town before you head in. Inside the parks you will usually have coverage at the visitor center and on the main approach roads, but not in the backcountry.

The apps you actually need in the USA
A surprising amount still runs on plain text messages in the USA. The Uber driver texts you, the restaurant lets you know your table is ready, the rental car company sends a pickup code, and almost every app wants to confirm a phone number when you create an account. WhatsApp barely features in everyday life there. With your own US number those messages arrive without a fuss — with a number from home, some services simply refuse. These are the apps you will actually use.
Uber
Runs in practically every larger city and will take you from the airport into town. The price is fixed before you ride and is charged to the card on file.
In small towns and rural areas there are often no drivers at all. At many big airports Uber and Lyft do not stop at the terminal either, but at a signposted pickup area — follow the signs for rideshare.
Lyft
The American alternative to Uber, often a few dollars cheaper. It pays to keep both apps open and compare the two prices side by side.
Only exists in the USA and Canada. Lyft asks for a number from the USA, Canada or Puerto Rico to sign up — your number from home often will not get you through.
Venmo
The app Americans use to send each other money: splitting a bill, paying a food truck, chipping in for the rental car. Plenty of small vendors ask for it first.
Effectively unusable for visitors: Venmo requires a US bank account and a US number that can receive text codes from American short codes. If someone asks you for Venmo, pay by card or cash instead.
DoorDash
The country's biggest delivery service. Brings food, and by now groceries and drugstore items too, right to your hotel room door.
The driver will text or call you if they cannot find the building — without a reachable US number your order ends up at the wrong door. A tip is asked for at checkout and is expected in the USA.
Yelp
The American review site for restaurants, breakfast spots, repair shops and hair salons. Opening hours are often more reliable than elsewhere, and at many restaurants you can join the waitlist in advance.
You have to leave a phone number for the waitlist. The text telling you your table is ready only arrives if that number can actually be reached.
GasBuddy
Shows what fuel currently costs at the stations near you. On a road trip that adds up noticeably over two weeks.
American pumps ask for a five-digit US ZIP code when you pay by card. European cards often fail there — go to the counter inside, give the pump number and pay there instead.
