Ubigi eSIM Review: Easy Data On The Go!

International data has gotten way easier in the last few years!

No more hunting down SIM kiosks at the airport — you just scan a QR code, tap a few buttons, and boom: data.

Ubigi is one of the newer eSIMs I’ve added to my arsenal, and in this review, I’m breaking down what it does well, where it fits into your travel plans, and how it actually works in real life.

What Is Ubigi?

Ubigi is a global eSIM service backed by Transatel, which is part of the NTT Group — one of the world’s major telecom companies.

In plain English: it’s not some random pop-up app that might disappear overnight. It’s built on real telecom infrastructure, with coverage across 200+ destinations worldwide.

Instead of buying a new physical SIM in every country, you install one Ubigi eSIM profile on your phone and then just add data plans for the countries or regions you’re traveling to.

No swapping little plastic cards, no store visits, no begging airport Wi-Fi to load a signup page.

Ubigi is mainly built for travelers, remote workers, and generally anyone who wants data abroad without touching their regular mobile plan.

Where Ubigi Works & Who It’s Best For

Ubigi offers data plans in more than 200 destinations around the world, including popular spots in Europe, Asia, the Americas, and beyond.

It’s especially handy if:

• You’re hopping through multiple countries on one trip.
• You don’t want to open a full-blown mobile plan just for a short visit.
• You want something you can install once and reuse on future trips.

For shorter trips (think vacations, work trips, city breaks, or a few weeks abroad), an eSIM like Ubigi is usually way easier than messing with local SIMs or international roaming.

For longer stays (like months in one country), I still usually recommend looking into local physical SIMs or local eSIM options eventually — they can sometimes beat everyone on price once you’re staying long-term.

But as a “land, have data instantly, and not stress” option, Ubigi fits nicely into the travel toolkit.

Ubigi’s Standout Features (The Actually Useful Stuff)

Here’s what makes Ubigi interesting compared to your average “scan this and hope it works” eSIM.

1. Your Plan Starts When You Land

With Ubigi, you can buy a plan up to 6 months in advance, but the clock only starts ticking when you arrive, and your phone connects to the local network.

So you can:

• Buy your data before your trip while you’re on good Wi-Fi.
• Not panic if your flight is delayed or you have an unexpected overnight somewhere.
• Know that your 7-day or 30-day plan isn’t quietly expiring in the background.

Travel prep with less brainpower required.

2. One eSIM Profile for ~200 Destinations

Once you’ve installed the Ubigi eSIM on your phone, you don’t have to keep scanning new QR codes every time you go somewhere they cover. You just log into the app or website and buy a new plan for your next destination or region.

That’s especially nice if you’re bouncing around a lot or if you travel several times a year. It’s basically “set it up once, reuse forever.”

3. 5G Where Available + Tethering Allowed

Ubigi offers 5G access in many destinations at no extra cost when available, which is ideal if you’re doing heavier stuff like working online, loading maps quickly, or uploading content.

They also allow tethering/hotspot with no weird restrictions, so you can share data with your laptop or travel buddy without the app throwing a tantrum.

4. Easy Top-Ups (Even If Your Data Is Gone)

If you burn through your data, Ubigi lets you top up via the app even if you don’t have any data left on your plan. They provide free access to the app specifically so you can add more data without hunting for Wi-Fi first.

This sounds small, but when you run out of data in the middle of nowhere and just need to buy more, it’s a lifesaver.

5. Home IP Feature (US & France)

One of the more unique things Ubigi offers is a “Home IP” option for people from the US and France. You can choose to use an IP address from your home country or from the country you’re visiting.

How to Check If Your Phone Works With Ubigi

Most modern phones support eSIM now, but here’s the quick test:

1. Open your phone app.
2. Dial *#06#
3. If you see an EID number appear, your device supports eSIM.

How to Set Up Ubigi eSIM (Website or App)

There are two main ways to get started: via the Ubigi website or the Ubigi app.

Option 1: Buy via Website (QR Code)

1. Go to the Ubigi website.
2. Pick your destination (or region) and choose a data plan that fits your trip length.
3. Create an account and apply code NINA10 at checkout for 10% off.
4. You’ll receive a QR code by email and/or on the screen.
5. On your phone, go to Settings → Mobile / Cellular → Add eSIM / Add Cellular Plan.
6. Scan the QR code and follow the prompts to install.

Once the eSIM is installed, you can turn it on when you land and let your phone connect.

Option 2: Buy via the Ubigi App

1. Download the Ubigi app on iOS or Android.
2. Open the app and follow the instructions to install the Ubigi eSIM profile.
3. Log in (they support biometric login like Face ID / fingerprint if your phone has it).
4. Choose your destination and data plan.
5. Apply NINA10 for your 10% discount.
6. Activate the plan and you’re good to go.

Both routes get you to the same place; it just depends if you prefer doing it on a laptop (website + QR) or fully on your phone inside the app.

Ubigi Pricing & Plan Types

Ubigi has a mix of:

• Local plans (single country)
• Regional plans (like Europe or Asia)
• Broader multi-country plans, plus
• A range from small data bundles (500 MB) up to unlimited data plans in certain destinations

My Ubigi Review in the US

For this round, I grabbed a Ubigi eSIM while I was back in the US for a visit — which is honestly where data can get ridiculously expensive if you don’t want to commit to a full carrier plan.

Setup was straightforward:

• I installed the eSIM via the app.
• Chose a US plan that covered my stay.
• Let it activate when I got into coverage.

Speeds were totally fine for what I needed: maps, social, email, and a bit of light work. Hotspot worked when I needed to connect my laptop, and I didn’t run into any random disconnects or “you can’t tether on this plan” nonsense.

Would this replace a full carrier plan if I were permanently based in the US? No. But as a short-term, low-commitment option while visiting, it did exactly what I wanted: gave me solid data without signing up for a traditional phone line.

When Ubigi Makes Sense (and When It Doesn’t)

Ubigi is a good fit if:

• You want easy, pre-trip setup so you land with data ready.
• You travel to multiple countries or travel frequently and like the “one eSIM, reuse everywhere” idea.
• You need hotspot/tethering and don’t want to fight your eSIM over it.
• You’re US- or France-based and like the idea of a home-country IP option for certain services.
• You’re visiting the US and want data without signing a regular phone contract.

Ubigi might not be your forever solution if:

• You’re staying in one country for many months and want the absolute rock-bottom local rates — in that case, a local SIM or long-term plan is usually worth looking into once you’re settled.
• You’re using tons and tons of data constantly (like heavy streaming all day). Some people prefer a local plan for that level of usage.

Personally, I use services like Ubigi as my “arrive and not panic” solution and sometimes stick with them the whole trip if the pricing makes sense. For longer stays, I often layer in local options later.

Ubigi Review: Is It Worth It?

If you’re looking for a reliable, easy-to-set-up eSIM for international travel (or a US visit) and you like the idea of installing a single eSIM once and reusing it around the world, Ubigi is absolutely worth a look.

Here’s the quick summary:

Pros

• Coverage in 200+ destinations with one reusable eSIM.
• Plans only start when you land, not when you pay.
• 5G access where available and tethering allowed.
• Top-ups even when you’ve used all your data.
• Backed by a major telecom group instead of a random unknown.
• Home IP option for US/France users.
