The best travel eSIM apps, by country, 2026.

A guide to travel eSIM apps. Compare global and regional data plans, unlimited options, the cheapest per-gigabyte deals, country plans for the USA, Europe and Asia, plus long-stay and business eSIMs, with a plain summary of coverage, price, and how each app actually works.

Find the right travel eSIM without the guesswork

Every eSIM app claims the widest coverage and the cheapest data, and the fine print rarely agrees with the homepage. Best eSIM Apps tracks the providers travelers actually install before a trip, sorted by where you're going and how you plan to use your phone once you land. Each listing says in plain language which countries a plan really covers, how the price works once you do the math per gigabyte, and who the plan tends to suit.

How we choose and rank the apps

We only list providers with a working app or website you can check yourself, and we confirm each one is still operating before it goes live, since this market has more dead brands and rebrands than most. We read the actual pricing page rather than a press release, note which mobile networks a plan runs on in its key destinations, and write our own summary instead of repeating the store listing. On each page, the established eSIM providers that travelers recognize come first. When a provider shuts down, gets folded into a parent brand, or its coverage quietly drops, we update the entry or remove it.

What to check before you buy

A few things separate a smooth landing from a frustrating one. First, read what "unlimited" actually means: several plans throttle speed hard after a daily cap, which is fine for maps and messaging but useless for a video call. Second, check whether the plan is data-only or includes calls and texts, since most travel eSIMs skip voice entirely and expect you to use an app like WhatsApp instead. Third, look at validity: a 7-day plan that starts counting down the moment you install it is a bad fit for a trip where you land three days after buying it, so buy close to departure or pick a plan with an activation window. Finally, check the top-up process before you need it, ideally in the same app, and see whether there's a refund window if a plan simply won't connect.

Device compatibility and unlocking

Not every phone can use a travel eSIM. Most iPhones from the XS onward and most recent Android flagships support eSIM, but a good number of phones sold with a carrier contract, especially in the US, ship locked to that carrier and can't install a second profile until it's unlocked. Check your phone's settings for an eSIM option before you buy, and if you're not sure whether your phone is unlocked, call your home carrier and ask, since a locked handset is the single most common reason a travel eSIM fails to activate at the airport.

Data-only versus calls and texts

Nearly every provider on this site sells data-only eSIMs: your phone gets internet the moment you land, but a call to that number won't ring anywhere, because there usually isn't a working phone number attached to it. Your home SIM or eSIM keeps working for calls and SMS over wifi calling where your carrier supports it, and apps like WhatsApp, iMessage, and FaceTime cover most everyday communication once you're online. This matters most for two-factor codes sent by SMS: if your bank texts a one-time code to your home number, make sure that SIM is still active (even in airplane-mode-plus-wifi) or switch to an authenticator app before you leave, because a data-only travel eSIM won't receive it.

Suggest a listing

Run an eSIM app or reseller that belongs here, or know one we've missed? You can submit a listing for review. We check coverage, pricing, and whether the company is still actively operating before anything goes live.

A note on what this is

We describe and link to these providers. We don't sell eSIMs ourselves, we aren't affiliated with any single network, and nothing here is a guarantee that a given plan will work at your specific destination. Coverage, pricing, and network partners change often, sometimes without much notice, so treat this as a starting point and confirm the current plan details on the provider's own site before you buy.
