Uzbekistan Sleeping Train & eSIM Review 2026: Stay Connected

---

My Uzbekistan Adventure

Honestly, I set off without much preparation.

As a 'J' personality type who loves to plan, I pretty much winged this whole 'P' trip!

It was my first time in Central Asia,

and there wasn't a ton of information available.

So, for this trip, I pretty much

relied solely on the internet to get around,

and that's no exaggeration!

Arrive at Tashkent Airport → Travel to Bukhara by sleeper train

→ Travel to Samarkand by train → Return to Tashkent by train

I had to survive this 7-night, 8-day itinerary on a single data plan,

and looking back, it feels a bit reckless, haha!

I've always used Usimsa eSIMs whenever I travel abroad,

and this time was no exception – I used Usimsa again.

Since I was so satisfied again,

and I hope many of you will try it too,

I'm bringing you a golden tip: if you purchase through the link below, you'll even get a 20% discount!

Here's what I felt after my trip to Uzbekistan in Central Asia,

along with all the unique details I've compiled.

First off, the regions I traveled to were

Tashkent, Bukhara, and Samarkand.

Since I traveled by sleeper train and regular train,

you might be curious about data connectivity on the train.

With the sleeper train, data connectivity varied depending on the station.

Sometimes it connected, sometimes it didn't, and this wasn't just with my Usimsa eSIM,

but also with the locals' phones.

Considering that some sections of the railway had weak connections,

I figured it was a limitation of the railway itself.

Once I arrived at the station, data reconnected normally,

so it wasn't a major concern.

Also, when using Yandex Go

or YouTube and Google Maps,

and even when using ATMs, I could use them without interruption.

Does my Uzbekistan eSIM really need to be unlimited?

When traveling to other countries, I habitually chose 3GB

or unlimited plans first.

This time, a 2GB Usimsa eSIM was completely enough!

The reason? Google Maps and ChatGPT offer free data!

Here, 'free' doesn't just mean no app fees,

it means the data itself isn't deducted,

so even with the map running, your data won't drain.

In Uzbekistan, local languages and

Russian are used far more than English,

so there were many places where even ordering a meal felt daunting just looking at the menu.

Whenever that happened, I'd use ChatGPT to translate and ask questions,

and since its data usage was free,

I could use it as much as I wanted without any worries.

Thanks to this, even though I chose a 2GB plan,

I traveled for 8 full days without any concerns about slow speeds.

Before your trip, you might be confused about the different types of Uzbekistan eSIMs available,

and which plan is right for your itinerary.

Check out the prices and options for global eSIMs covering 151 countries via the link below!

You can also instantly see the 20% discounted price.

For your reference, it's not just for Uzbekistan,

but also for various other Central Asian destinations like Kazakhstan and Kyrgyzstan.

When traveling across diverse Central Asian countries,

you can simply use the plan covering 5 Central Asian countries / 151 global countries.

I chose this eSIM because reviews mentioned it worked flawlessly not only in Uzbekistan but also in Kazakhstan and other Central Asian countries.

After trying it myself, I immediately understood why countless travelers rely on this data plan.

Uzbekistan eSIM Drawback: Can't install in your home country?

Personally, this part was a bit of a letdown,

and it was different from other countries I've visited.

For most eSIMs, you can pre-install them in your home country (e.g., Korea) before departure,

and use them immediately after arriving at your destination.

However, for Uzbekistan, local installation was a must.

The problem was that the free Wi-Fi at Tashkent Airport wasn't always reliable...

So, my friend, who managed to connect to the Wi-Fi first,

installed their Usimsa eSIM,

and I borrowed their hotspot to install mine.

I'm sharing this detail because it's good to know in advance!

If you're traveling with companions, I recommend one person connecting to the free Wi-Fi first

and then sharing hotspots with each other.

You might be a little flustered by the mandatory local installation,

(I certainly was at first!)

but I hope my experience helps you avoid the same trial and error...!

If you're going to use it anyway, it's always better to get it 20% cheaper, right?

How was the real-world satisfaction?

When calling Yandex Go, Uzbekistan's essential mode of transport,

the connection was consistently strong without any interruptions.

Even when withdrawing local currency from ATMs,

the data stayed connected, allowing me to complete transactions smoothly.

There weren't absolutely zero dead zones, of course,

but those were due to regional issues, like the train tracks I mentioned earlier,

not problems with the eSIM quality itself.

During my trip, I met some travelers on a package tour,

who couldn't find their way because their internet wasn't working.

We helped them find their way, and seeing that situation,

I once again felt how much more stable the Usimsa eSIM was

compared to other data products.

I recommend the Usimsa eSIM for these types of travelers:

✅ Those traveling to regions with limited information, like Central Asia

✅ Those heading to destinations where translation app dependence is high, such as local language or Russian-speaking areas

✅ Those with itineraries involving travel between multiple cities by train

✅ Those who frequently use Google Maps and ChatGPT on the go

✅ Those who want to get a 20% discount and buy it affordably, if possible

Q. How many GB should I choose for the Uzbekistan eSIM?

Since Google Maps and ChatGPT offer free data,

if you primarily use it for maps and translation,

I think a 1GB plan should be enough.

If you watch a lot of videos or use social media extensively,

you might want to consider the 2GB option or more.

Q. How do I get the discount?

If you purchase through the link below,

you can buy it at a 20% discounted price from the original.

The discount is applied automatically just by accessing the link, no separate coupon code needed.

You can snag a 20% discount if you purchase through the link above!

Q. Can I pre-install my SIM card for Uzbekistan from back home?

Nope, it's only possible to install it once you're there.

Since airport Wi-Fi might not always be super smooth,

I'd really recommend planning ahead so you can easily share a hotspot with your travel buddies.

Q. I'm taking a lot of trains; will my data connection stay strong throughout?

It's generally strong at the stations,

but along the train tracks themselves, even local carriers tend to get a bit weaker.

It reconnects instantly once you arrive at your destination, so I didn't experience any major inconvenience.
