PCMag has been covering eSIM technology since it first broke onto the scene. We were the first to use T-Mobile’s eSIM app for iPhones back in 2018. Since then, eSIMs have become a lot more common, especially after Apple removed the physical SIM card tray from iPhones in the US. Whether you're looking to save money on mobile service for international travel or just need an extra line, an eSIM can help you stay connected without needing to order, receive, and swap a physical SIM card. Read on for the best eSIMs we've tested for a variety of different use cases, followed by everything you need to know to pick the right eSIM for you.

Pros & Cons
Why We Picked It
MobileX doesn’t offer global coverage, but it does provide fast and reliable access in the US on Verizon’s network. We appreciate the service’s learning period, which tracks your usage and recommends a plan that fits your needs. Also, this is the only eSIM service on this list that includes a local US phone number and messaging in addition to data.

Cost-cutters who want reliable coverage: For those who want an alternative to the big three carriers, MobileX is a great choice for pay-as-you-go service. You get the dependability of a big network without the big price tag.
Those who want plan flexibility: Instead of locking in a specific plan, MobileX’s plans are month-to-month. This lets you change things up whenever you want, depending on how you’ll use your phone.

Buying Guide: The Best eSIM for 2026
Does My Phone Support eSIM?
When selecting an eSIM, several factors should be taken into consideration. Most services operate similarly and require an internet connection (Wi-Fi) to get started, so be sure to set up your eSIM before you leave home. To install it, you typically scan a QR code or download the provider’s app, which lets you manage your account and track usage from your phone.
Most modern phones support eSIM, but not all of them do. Apple added support starting with the iPhone XS in 2018, Google began with the Pixel 2, and Samsung’s Galaxy S line has supported eSIM since the Galaxy S21. To check your device, dial *#06#. If you see an EID number, your phone likely supports eSIM; however, you can confirm this by searching the web for your phone model. You can also check the eSIM provider’s site, which usually offers device compatibility lists and setup instructions. Your device must be unlocked and not tied to a carrier for our recommendations to work.
What Kind of eSIM Service Do You Need?
Other than MobileX, the eSIM services we list here provide data only, which is good for email, maps, messaging apps, social media, and browsing the web. Traditional phone and texting apps will not work on these kinds of plans, but messaging apps like WhatsApp or Zoom will function if you have a fast enough connection, as will iMessage and FaceTime if you're using an iPhone.
If you need a regular phone number for calls or texts, look for a local provider at your destination that offers eSIMs that include voice and SMS support. If you need your own number to work while travelling, you'll have to settle for roaming with your existing service provider, which can cost as much as $10 per day.
You don’t need to limit yourself to a single-country plan. Every global eSIM provider on this list offers country-specific plans, in addition to regional or global options that cover multiple destinations with a single eSIM. This is ideal if you’re hopping between countries.
Recommended by Our Editors
The duration of eSIM plans varies, with some services offering coverage for just a day, and others stretching for weeks or months. Pick a plan that fits the length of your trip to avoid overpaying.
How Much eSIM Data Do You Need?
If you’re unsure about how much data to buy, check your phone for information on how much you already use:
- On Apple iPhones: Settings > Mobile Data
- On Google Pixel phones: Settings > Network & Internet > SIMs > App Data Usage
- On Samsung phones: Settings > Connections > Data Usage
From there, you can do some basic math to figure out how much data you need over a given time period. To minimize data usage on metered connections, download maps and media in advance, set music and video apps to offline or low-quality modes, and disable automatic backups, such as Google Photos, unless you're connected to Wi-Fi.
You can stretch your eSIM's data allotment by being mindful. Streaming video consumes data quickly, although usage varies depending on resolution and bitrate. Monitor your habits to maximize the effectiveness of your plan.
