Picture this: you land in a new country, switch off airplane mode, and brace for the roaming charges your home carrier is about to inflict. Those fees are extortionate, and, in extreme cases, can quietly cost more than a night at your hotel. That’s why, these days, travelers are switching to travel eSIMs instead. The trouble is, most travel eSIMs on the market are data-only.
That gap matters more than people expect. Data-only means relying on Wi-Fi for every call, and it means missing the things that still run on real numbers: local SMS alerts, bank verification codes, or simply ringing a taxi or hotel front desk.
eSIMo closes the gap by bundling global data, a secondary phone number, and proper calling and SMS into a single app. Our internal testing revealed that for travelers who need calling alongside data, eSIMo is the default choice.

What is eSIMo?
eSIMo (esimo.io) is a digital SIM provider built for one job: keeping you online and reachable while traveling, without a roaming bill. eSIMo has operated in its target markets since 2023 and holds the #1 position in them, a track record that’s earned rather than assumed.
It offers coverage in 200+ destinations, which puts it in the same global tier as the biggest names in the eSIM space. Plus, it covers the countries most travelers actually care about rather than padding the list with less popular destinations.
An eSIM is just a SIM card built directly into your phone, so there's no tiny piece of plastic to buy, to install, or lose. If you're carrying a reasonably modern iOS or Android device, the hardware is already sitting inside it. You can simply activate eSIMo through the app, and that's the whole setup. No store visit, no fiddling with a SIM tray and a paperclip at the airport.
What sets eSIMo apart from the crowd is who it's actually built for. Most travel eSIMs quietly assume you only want data. eSIMo is aimed at people who need more than that: digital nomads running their work life from a laptop and a phone, corporate travelers who can't afford to miss a verification code or a client call, and vacationers who just want to ring a local restaurant or hotel without a second thought.
In short, it's a connectivity tool for anyone who wants a local number and real calling alongside their data, without paying their home carrier's roaming rates.
Core capabilities: what sets eSIMo apart
Here’s where eSIMo separates itself from the data-only crowd – four features that matter most for travelers who need to do more than just browse.
Core capabilities: what sets eSIMo apart
Almost every travel eSIM on the market routes data and nothing else, which leaves you tethered to WhatsApp, Messenger, or FaceTime for every conversation and locks you out of anything that needs an actual phone line.
eSIMo takes a different route. Its app lets you place outbound calls, with rates starting at just $0.01/minute for destinations like the US and Canada. That means you can ring a local landline, or confirm a booking, all without hunting for Wi-Fi first. Plus, you can also receive SMS directly.
One thing to keep in mind is that the eSIMo calling feature is built for everyday use, not emergencies, and it can’t dial local emergency numbers like 911 or 112. So, keep your regular SIM active alongside eSIMo to make sure you're covered if you ever need to reach emergency services.
Virtual second numbers
Virtual second numbers is the feature I’d highlight privacy-minded travelers to first. eSIMo lets you lease a virtual second number, which sounds minor until you’re actually abroad and realize how often you need one.
For instance, when you sign up for a local ride-sharing app, it usually requires a phone number to send a verification code. Booking confirmations, delivery updates, and one-time passwords all tend to land on a real number rather than an app.
A second number handles all of that without exposing your personal line to foreign networks and services. You give out the temporary number, receive the calls and SMS you need, including OTP verifications, and keep your home number completely private.
The app also adds practical controls like call forwarding, so you can route your domestic line straight to the eSIMo number, and caller ID options to show or hide your outgoing identity.
For anyone who values keeping their primary number off unfamiliar platforms, it's genuinely useful.
The eSIMoney cashback system
Most eSIM providers take your money, and that's the end of the relationship. eSIMo tries to keep you coming back with eSIMoney, a built-in rewards program that puts cashback on your purchases and stacks extra credit on top through referrals.
It works fairly simply – you buy a plan, top up data, or invite a friend, and you earn a balance you can put toward future trips rather than watching the money simply disappear.
For frequent flyers, eSIMo is very attractive. The savings on any single purchase are easy to shrug off, but across a year of plans and top-ups, they compound into a real discount on your next eSIM. The invite-and-earn side makes it even more appealing if you're the type to recommend a service that works, since every friend who signs up feeds your own balance.
It's a small but genuine edge over providers that offer no loyalty mechanism at all, and it rewards exactly the travelers who buy eSIMs most often.
Instant app-based installation
eSIMo keeps the setup simple. The flow is quick: check that your device supports eSIMs, download the app, pick your destination country, and install the eSIM straight away using either a direct in-app button or a QR code scan. There's no waiting on a physical card in the mail and no SIM tray to wrestle with.
In practice, that means you can have a plan loaded and ready before you even leave home, then connect to a local network within minutes of landing. The app doubles as your control center for everything afterward, so buying more data, switching plans, or checking your balance all happen in the same place.
For first-time eSIM users who find the whole concept a little intimidating, that single-app simplicity removes most of the friction.
eSIMo plans and pricing structure
eSIMo’s pricing is its strongest asset. Local plans for a single country start at $3.90 for 1GB and scale up depending on how much data you need, covering over 200 destinations.
The standard data tiers offer 1GB, 3GB, 5GB, 10GB, and 20GB options, so you can match the plan to the trip rather than overpaying for data you'll never touch. Heavy users aren't left out either: eSIMo also offers unlimited plans for travelers who'd rather not think about data caps at all.
Moreover, regional plans bundle neighboring countries together. For full global coverage, the 105-country plan runs from $14.90 for 1GB up to $199.90 for 20GB.
Here's how the eSIMo pricing for popular travel destinations lays out:
| Country | 1GB | 3GB | 5GB | 10GB | 20GB |
| United States | $3.90 | $8.90 | $13.90 | $21.90 | $34.90 |
| United Arab Emirates | $3.90 | $8.90 | $12.90 | $20.90 | $34.90 |
| Turkey | $3.90 | $6.90 | $9.90 | $13.90 | $19.90 |
| Egypt | $3.90 | $9.90 | $14.90 | $24.90 | $38.90 |
| Japan | $3.90 | $8.90 | $12.90 | $19.90 | $28.90 |
| Morocco | $3.90 | $9.90 | $15.90 | $29.90 | $49.90 |
| UK | $3.90 | $6.90 | $10.90 | $17.90 | $25.90 |
| Saudi Arabia | $3.90 | $9.90 | $14.90 | $21.90 | $31.90 |
| Greece | $3.90 | $9.90 | $13.90 | $19.90 | $29.90 |
| Canada | $3.90 | $10.90 | $13.90 | $24.90 | $39.90 |
Because the voice layer is built in, calling is billed separately from data and stays cheap. Outbound VoIP rates start as low as $0.01/minute for destinations like the US and Canada, so adding voice to your trip costs cents rather than the painful per-minute rates a home carrier would charge for roaming.
Running low on data mid-trip isn't a problem either, since the app lets you buy more data or add call credit on the spot, in a few taps, without reinstalling anything or hunting for a new eSIM. Your existing plan simply refills, and you keep moving.
Who is eSIMo for, and who isn't it for?
eSIMo is built with a specific kind of traveler in mind, and it shows. To help you work out whether it fits your trip, here's a simple breakdown of where I think it earns its place, and where another provider might serve you better.
eSIMo vs Airalo vs Holafly
To show where eSIMo actually lands, I lined it up against the two biggest names travelers usually weigh it against: Airalo, the budget data specialist, and Holafly, the unlimited-data heavyweight. Here's how they compare across the three things that matter most.
| Feature | eSIMo | Airalo | Holafly |
| Voice calls and SMS | ✅ Built-in VoIP calling and receiving SMS | ⚠️ Only on Discover+ global plans | ❌ Data-only |
| Secondary phone number | ✅ Yes | ⚠️ Only on Discover+ global plans | ❌ No |
| Calling rates | From $0.01/min | No native voice | No native voice |
| Small data bundles | From $3.90 | From $4.00 | Limited, pricier |
| Hotspot/tethering | ✅ Yes | ✅ Yes | ⚠️ Often restricted |
| Loyalty rewards | ✅ Up to 10% cashback + referral program | ⚠️ Referral credit | ❌ No |
eSIMo wins outright on communication: it's the only one of the three industry-leading eSIM providers with proper built-in voice, SMS, and a leasable second number. Moreover, its outbound rates from $0.01/minute undercut anything you’d pay for roaming.
On price, eSIMo is competitive with both rivals depending on the destination, and it’s the only one that pairs that pricing with unlimited plans, calling, SMS, and a second number in a single app.
eSIMo pros and cons
Just like any other top eSIM provider for international travel, eSIMo has clear strengths and a few trade-offs worth weighing before you commit. Here's the quick rundown after testing it.
Verdict: is eSIMo worth it in 2026?
To sum up, if you need more than raw data on the road, eSIMo is the most versatile option out there. By folding international calling, SMS, second numbers, and global data into a single app, it does what almost no competitor does, making it the best all-in-one travel connectivity tool we've tested this year.
The pricing backs that up, not just the feature list. Plans start at $3.90, unlimited options exist for travelers who don't want to think about caps, and the eSIMoney cashback program means the money you spend on one trip quietly discounts the next. Add in hotspot support and the new Business platform for teams, and eSIMo covers nearly every use case a traveler could throw at it.
Thus, eSIMo is definitely worth it in 2026 – especially for digital nomads and business travelers who need voice and number flexibility alongside their data.
