Three simple steps to stay connected in the United States
1
Depending on your usage and length of stay, select the package that best suits your needs.

2
Whether from the voilà app by clicking on "Activate card" or by scanning the QR code received by email.

3
Your plan will activate automatically once you arrive at your destination. You can track your usage in real time via the voilà app.

An eSIM card is your cell phone plan stored directly in your phone. No cards to insert, no queues at the airport. You download your eSIM profile in just a few minutes, and your Internet connection is automatically activated as soon as you land in the United States.
ESIM replaces the physical SIM card with a digital profile installed directly on your device. You scan a QR code, the profile is installed, and that's it. There's no risk of losing your SIM card, and no operator stores to find on site.
Your eSIM voilà activates automatically on arrival in the United States, with no need for Wi-Fi or fiddling. Connection sharing included on all packages: plug in your computer or share mobile data with friends and family at no extra cost. TikTok, banking applications, Google Maps: everything works, nothing is blocked.
Your usual phone number continues to work for calls and messages. The eSIM here manages your mobile data in the United States in parallel. One phone, two profiles active at the same time, or several eSIMs if your trip covers several countries.
The eSIM guarantees you an uncompromised experience during your stay in in the United States.

More than 100,000 travelers are already using the voilà eSIM to stay connected abroad. Regarding eSIM prices in the USA, plans start from as little as €1.60, using local network operators with 4G/5G.
Bertrand Vasseur
3-week road trip in the American West: Los Angeles, Las Vegas, Grand Canyon, Yosemite, and then San Francisco. 50 GB plan, excellent 5G eSIM coverage in big cities (the best coverage I've ever had), and very decent 4G over long distances. I hesitated between this and Holafly with its unlimited data on T-Mobile and AT&T networks. In the end, the best eSIM plan for my budget was still voilà, much cheaper, and the eSIM cost was unbeatable. Honest downside: in remote areas of national parks like Death Valley, the signal becomes unstable, but that depends on local carriers, not the eSIM. Tracking consumption on the app is super practical.
Camille & Lou
We went on a girls' trip to New York and were looking for a cheap eSIM to avoid getting ripped off. After comparing, voilà was about €15 cheaper than Airalo for a similar plan. The 5G worked perfectly everywhere, from Manhattan to Brooklyn. Google Maps, Uber, Instagram, TikTok, FaceTime—everything worked without a single bug. I had taken 20 GB for 10 days and it was more than enough, but I still topped up 5 GB directly in the app in 2 minutes. The best value for money in our eSIM comparison.
Quentin Mercier
Road trip USA Canada (New York, Boston, Montreal, Toronto), 30 GB on a plan designed for North America. A single profile for both countries, so no more need to swap cards at the border. With Airalo, I would've had to buy two separate plans and pay more. Reliable internet connection on both sides, perfect for Maps and booking hotels on the go. No blocked apps, usage tracking in the voilà app. In terms of eSIM flexibility, one single card for all of North America—this is truly the future of travel eSIMs.
Martine Lévêque
Not tech-savvy at all, this was my first eSIM, for a week in Chicago. 5 GB plan, installation via the QR code and the instructions received by email, nothing new or complicated to learn. Reliable 4G/5G coverage in the city. Honest downside: you have to remember to enable data roaming yourself in the settings upon arrival, otherwise it won't connect automatically. Once that's done, you don't have to touch anything else, and the human support helped me in a few minutes on WhatsApp. For ease of use, it was perfect for a first time, I recommend it to travelers like me.
Inès Caron
City trip on the West Coast, 20 GB for 12 days between Los Angeles, San Francisco, and Las Vegas. Network stability was top-notch in the city, 5G everywhere, and speeds were more than enough for streaming in the evening at the hotel. I had used Saily last year (Verizon network), which was okay, but the voilà eSIM price was lower for the same duration. Activation upon arrival at LAX took just one minute, and the hotspot feature let me connect my boyfriend's tablet. Nothing to complain about regarding coverage.
Sofiane B.
Important to know: I thought about getting an eSIM with calls, but eSIM calls aren't included. It's data only, no local US number, so no regular calls or SMS, and no unlimited calls. Honestly, for 15 days in Chicago and New York, WhatsApp and FaceTime do the whole job for calling family. I had looked at Ubigi before, but voilà was easier to use and cheaper. 10 GB, stable connection, instant activation. The eSIM features match exactly what you expect from a travel data plan, nothing more, nothing less.
Anna
Super option for staying connected in New York. Installing your voilà eSIM is quick and easy, so you can have internet without any headaches as soon as you arrive at JFK. I got 10 GB for a week in Manhattan and Brooklyn, and the connection is reliable for everyday use: social media, GPS, or looking up great spots. It's clearly a practical solution to avoid roaming fees and enjoy your trip with peace of mind.
Famille Lacombe
Family trip to Miami and then Orlando for the theme parks, 30 GB of data sharing in a single plan. No roaming fees, no bad surprises when we got back. We checked in advance that every device was eSIM compatible, and installation was immediate via the QR code received by email. The eSIM plans are clear, with packages tailored for the whole family, and the eSIM benefits are obvious for parents: Maps, WhatsApp on every phone to manage the kids, and photos sent live to the grandparents. We tracked everyone's usage in the voilà app. Reliable coverage everywhere in Florida.
Gaëlle Riou
Before, I used to buy a local SIM card at an AT&T or Verizon store upon arrival, costing between €40 and €60 with the long queues at JFK—a total nightmare. With voilà, the eSIM is activated before departure and you're connected as soon as you land. I placed my order on the website, received the QR code by email, and activation was instant. I got a 20 GB plan for two weeks in New York and Washington, with eSIM rates that are much lower than local carriers. No more physical SIM cards for me to install, and the human support team replied quickly when I had a question.
