eSIM carriers worldwide for iPhones and Android devices in 2026

Top international eSIM carriers 

If you’re traveling across multiple countries, an international eSIM provider is often more convenient than relying on a single mobile network operator. Instead of swapping SIM cards or buying a new plan in every destination, you can activate an eSIM before you leave and stay connected across most continents. If you’re new to the technology and wondering what an eSIM is, it’s a digital SIM that lets you activate a mobile plan without inserting a physical SIM card.

eSIM carriers in the United States 

The largest carriers that support eSIM in the USA are AT&T, T-Mobile, and Verizon, while prepaid providers such as Mint Mobile, Visible, Cricket Wireless, US Mobile, and Google Fi Wireless also offer eSIM on compatible devices. T-Mobile's prepaid brand is available as an eSIM Metro option too, and if Visible is your pick, our Visible eSIM guide covers its setup in detail. A Boost Mobile eSIM is another prepaid option, now running on AT&T's nationwide network. If you’re a U.S. resident, these providers offer everything from prepaid to postpaid plans. If you’re visiting, though, you don’t necessarily need to sign up with a local carrier. 

Saily gives travelers access to reliable mobile data by partnering with U.S. networks, so you can get online as soon as you arrive — without comparing dozens of local plans after a long flight. If your trip includes Canada or Mexico as well, eSIM plans for North America let you stay connected across the region with a single eSIM.

Good to know: The three major U.S. networks — AT&T, T-Mobile, and Verizon — provide nationwide coverage, while smaller carriers typically use one of these networks. That means your choice often comes down to pricing, features, and customer service rather than coverage alone.

eSIM carriers in Europe

Europe has one of the world’s most developed eSIM markets, with major operators supporting eSIM across most countries. Well-known providers such as Orange, Vodafone, Deutsche Telekom, Telefónica (O2 and Movistar), Swisscom, and TIM offer eSIM plans for residents — in the UK, for example, you can get a Three eSIM alongside options from EE, O2, and Vodafone — while travelers can also use Saily to stay connected across multiple countries with a single plan. If you’re planning a multi-country trip, an eSIM plan for Europe makes it easy to keep the same mobile connection from one destination to the next.

How to choose the best eSIM carrier 

The best eSIM carrier depends on where you’re traveling and how you plan to use your phone. Before buying a plan, compare these factors:

• Coverage: Make sure the provider offers reliable service in your destination. Some specialize in individual countries, while others cover entire regions or even the world.

• Network quality: Check which local mobile networks the provider partners with. Faster speeds and stronger coverage can make a noticeable difference, especially if you’ll be relying on maps, video calls, or mobile hotspots.

• Pricing: Compare the cost per gigabyte rather than just the total price. The cheapest plan isn’t always the best value if it comes with limited data.

• Data allowance: Think about how much data you’ll actually use. A weekend city break doesn’t need the same plan as a month-long backpacking trip.

• Prepaid or postpaid: Most travel eSIMs are prepaid, making it easier to control your spending. If you’re looking for a long-term mobile plan, a local postpaid carrier may be a better fit.

• Device compatibility: Not every phone supports eSIM, and some carrier-locked devices can’t use a different provider. Check compatibility before purchasing.

• Activation process: The best providers let you activate your eSIM in just a few taps through an app or by scanning a QR code, rather than sending you on a treasure hunt through your phone’s settings.

• Customer support: If something goes wrong abroad, responsive support can save both time and stress. Look for providers that offer 24/7 assistance.

• Trip length: A short holiday may only require a small prepaid plan, while frequent travelers often benefit from regional or global plans that work across multiple destinations.

If you’re looking for an option that ticks most of these boxes, Saily is worth considering. It offers prepaid data plans in more than 200 destinations, partners with trusted local networks, includes built-in privacy features like ad blocking and web protection, and makes it easy to manage everything from one app. 

Simply download an eSIM app, choose your destination, install your eSIM, and you’ll be ready to connect as soon as you arrive.
