How does Simbye eSIM work for the USA?
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. Your month starts on the day you buy — so order a few days before you fly.
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.
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.
Check Device Compatibility
Make sure your device supports eSIM before purchasing
Which networks will you be on in the USA?
Your USA eSIM connects to AT&T on its own — there is nothing for you to set up.

The eSIM is fixed to AT&T. As soon as you land 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 United States. At the gate in JFK, Newark, LAX or Miami International you are usually online before you reach baggage claim. In New York, Los Angeles, Chicago, Houston, Miami, San Francisco, Boston and Seattle you will normally 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 American network, not just AT&T — if you are planning a road trip through the national parks, download your maps for offline use before you set off.
eSIM or a local SIM card in the USA?
Here the eSIM gives you both: a US number with +1 for calls and texts, installed before you fly. A carrier store means a queue, a form, often your passport anyway, and sales tax added at the register.
| Feature |  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 for calls and texts is included | Also available, but it takes time at the counter |
| ID and registration | Not needed | There is no such requirement in the USA, but a carrier store will often still ask for your passport |
| Prepaid or contract | Prepaid: the runtime ends by itself, nothing renews | Prepaid exists too, alongside the monthly plans the stores mainly advertise |
| 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 |
For most travelers the eSIM is the simpler choice: set up before departure, no queuing on arrival.

Frequently Asked Questions about United States eSIM with Calls & Phone Number
Data, calls, real phone numbers, top-ups and setup — everything you need to know before you buy a Simbye eSIM.
You can buy an eSIM for the USA right here. You buy the eSIM online, pay by card and get the QR code by email within minutes — no store visit, no shipping, no waiting for a plastic SIM card.
Yes, you get an American phone number. This is a US eSIM with phone number: a real +1 number for calls and texts inside the USA, including the verification codes that American apps, rental car companies and restaurants send out.
Yes, you can keep your number from home. The eSIM sits in your phone as a second line and your usual number stays active next to it. Switch data roaming off for the home line and you will browse through the US eSIM while people can still reach you on your old number.
No, it doesn't work in Canada or Mexico. This eSIM works in the USA only. For a trip across the border you need a separate solution.
Yes, the data really is unlimited, so you browse without a data cap. After 50 GB at full speed it is slowed down: maps, messengers, email and music keep working, high-resolution streaming does not.
No need to register or show your passport. There is no registration requirement for prepaid lines in the USA, and none at all for the eSIM. You buy it, you get the email, that is it.
Yes, you can call home from the USA — international calls are included. Around 50 destinations, Germany among them, can be called without a minute limit, landlines and mobiles alike. The remaining countries come with a fixed monthly allowance of minutes.
An eSIM for the USA starts at 23,95€; the final price depends on how long you stay, shown in the table above with the American number and data allowance included. Pick the number of days that matches your trip: a short business visit and a month-long road trip use different plans.
Yes, eSIM is available in the USA — AT&T, T-Mobile, Verizon and US Cellular all support it, and iPhones sold in the US have been eSIM-only since the iPhone 14. An eSIM for the USA is a digital SIM card built into your phone. You don't need a contract with an American carrier: this plan runs on AT&T's network with a real US number, so you connect right after landing.
The best eSIM for the USA depends on what you need besides data. This one runs on AT&T, one of three nationwide networks, with unlimited data and a real +1 number for calls and texts, which helps with restaurant bookings, rideshare drivers and verification codes. If you only want data for a short city stay, a plain data plan is simpler. Yellowstone, Death Valley and canyon country stay thin.
Yes. Because you get a real phone number, SMS verification codes arrive directly on your phone — so you can sign up for or verify WhatsApp, Telegram, banking apps and almost any service. No extra app required.
No. This is a real eSIM with a real number that works natively on your phone — calls use your normal dialer and texts land in your phone's Messages app. The Simbye app is optional and only used to manage your plan.
Yes. You can make and receive calls and SMS with your included number — just like a local SIM, with no contract and no roaming bills. International calls are included as a set number of minutes depending on your plan.
