Best 3 GB eSIM for United States 🇺🇸

No, a USA eSIM will not work in Canada. To use mobile data in Canada, you need to buy a Canada eSIM or a North America regional eSIM, which works in the USA, Canada, Mexico, and Puerto Rico with a single eSIM.

If your home carrier doesn't offer free or cheap roaming - then yes. In most cases, you will pay less for a 10 GB eSIM data plan than you would pay for 10 GB of data roaming. Many carriers (this may vary by the country you live in) charge you per each STARTED GB. It means that even if you used 1.2 GB, you will pay for 2 GB. With a prepaid eSIM, you pay upfront for the amount of gigabytes you choose. We will notify you about your data usage, and you can always buy more. Even when you use the entire data plan, you can still top up the eSIM, so you don't have to make any decision upfront. Go to the US and see how much data you're using.

You can either make a purchase on this website or download the WonderConnect app and finalize the purchase there. Scroll up and select one of the data plans. Click "Buy now" to continue to checkout. There, we will ask you to select a payment method and create an account. Your eSIM is available immediately after the purchase - you will receive an email with a QR code for installation. Your eSIM is also available in your web account and in the WonderConnect app.

If your phone doesn't support eSIMs, check these options:

Contact your carrier and ask for special roaming offers. Make sure you know the rates upfront and ask about preventing extra charges by blocking data transfer after an agreed threshold. If roaming fees are acceptable, this might be the option for you.

Buy a local SIM card. But instead of doing it at the airport (where starter packs are often more expensive), go to a local store - it can be a local carrier store if you want to discuss the details and compare offers, or 7-Eleven, Walmart, CVS, Target, and the majority of stores and gas stations. An American SIM card comes with a local phone number.

You can buy an eSIM that will work in the US online. We will deliver it immediately to your email. Our eSIMs are data-only. It means you will get a mobile data plan that works across the states, but you won't have a local number. You can complete purchase now and install the eSIM before the trip.

United States eSIM is for tourists, road-trippers, and business travelers visiting American destinations like New York, California, or Florida. Having a dedicated data package gives your phone mobile internet access to call ride-shares, navigate driving routes on maps, and use messaging apps without taking out your primary physical SIM card.

No identity verification steps, passport photo uploads, or official account registrations are required prior to purchasing your eSIM. Simply select your data volume online, complete checkout, and scan the delivered QR code to configure cellular data on your device.

You can purchase your USA eSIM online via WonderConnect right before departure. After completing payment, your digital QR code is delivered instantly by email or through the mobile app, allowing you to install the eSIM onto your phone in a few minutes before boarding your flight. However, installing an eSIM requires a stable Wi-Fi or mobile data connection on your primary SIM. Please make sure you are connected to a strong internet during setup.

You can purchase prepaid data-only eSIM packages directly on the WonderConnect platform. Whether you are traveling within the United States or looking for regional North American data connectivity, checkout takes just moments online, and installation details are delivered digitally to your inbox.

Yes! You can purchase your travel eSIM even after arriving at your destination. The only difference from buying it before your trip is that we'll guide you to activate it immediately, allowing you to connect to a local network right away.

With travel eSIM you decide when to buy it - either before the travels, on the go using WonderConnect app, or after you arrive at your destination.

Usually, an eSIM plan starts when you first connect to mobile data at your destination.
You can install the eSIM anytime - even weeks before your trip. Installation does not start the validity period (unless you bought an eSIM for your home country; or a package that includes coverage for your home country. Example: Europe → Germany).

The countdown begins when your eSIM connects to a supported mobile network. For this to happen, your eSIM must be turned on and selected as your mobile data line.

eSIM prices for United States start at £2.50.

To use an eSIM, your device needs to be eSIM-compatible and carrier-unlocked. If you find your phone on our compatibility list, it most likely supports eSIM technology. In some cases, eSIM compatibility depends on where your phone model was manufactured. That's why we advise you to check our list before you buy one of our United States eSIM plans.

Carrier-unlocked means your home carrier (your mobile service provider) isn't restricting your phone from connecting to other networks. While carrier locks are becoming less common, if you're unsure, it's best to contact your provider. Just ask if they allow the use of digital SIM cards/eSIMs. If they do, you're free to avoid high roaming costs and enjoy affordable eSIM mobile data!
