The first practical mistake I made in Uzbekistan happened almost immediately after landing.
At Tashkent Airport, I bought a SIM card. I was tired, newly arrived, and excited by the word unlimited. The plan cost around 20 USD for one month. At that moment it felt convenient. Looking back, I would not do it again.
For most travelers, a much cheaper package is enough. In the city, I later saw SIM options around 70,000 UZS, and packages in the 5 to 6 USD range can already give a very large amount of data, often around 60 to 70 GB. For a normal one-month trip, that is more than enough unless someone is uploading heavy video every day or using the connection as a full-time work line.
My first advice is simple: if you buy at the airport, do not automatically choose the expensive unlimited plan just because it sounds safe.
The airport is convenient because it solves the first hour of arrival. You can open maps, call a taxi, message your hotel, translate something, and get moving without stress.
That convenience has value.
But if you already have roaming for the first few hours, or if you can reach your stay without local data, buying in the city is usually better. SIM cards are easy to find in local shops, around transport areas, and in ordinary neighborhoods. You normally need your passport, choose a package, and the shop activates it for you.
If I were landing in Tashkent again, I would either buy the cheapest useful airport package or wait and buy the SIM outside the airport.
The SIM card was not the most important lesson.
The phone registration rule was.
When you bring a foreign phone into Uzbekistan, the device can work for a limited period before registration becomes necessary. For a normal tourist staying less than two months, this may never become a problem. That is why many visitors do not even discover the rule.
But if you stay longer, or if you leave and return within a short period, it matters.
In my case, the phone continued working for roughly two months. After that period expired, it still worked for about three extra days before the restriction became noticeable. I would not treat those extra days as a rule. I would treat them as luck.
If you plan to stay close to two months or return to Uzbekistan soon after leaving, ask about phone registration as early as possible. Do not leave it for the final week.
I had two smartphones with me.
That became useful when my main phone registration window became a problem. For the additional days I stayed in Uzbekistan, I used my second phone as a hotspot and calling device.
Most travelers may not carry two phones. For a short trip, that is fine. For a long trip, or for someone working remotely while moving, a second device can become a real backup plan.
The lesson is not that everyone needs two phones. The lesson is that phone registration is not theoretical if the trip becomes longer than expected.
One small thing confused me in Uzbekistan.
In many cases, when buying a mobile connection, people seemed to provide two SIM cards or talk about the connection in a way that felt different from what I was used to in India. I do not want to pretend I fully understood the system.
But from a traveler point of view, the practical process was still easy: give passport, choose package, activate SIM, use the internet.
I used Uztelecom for most of my trip.
My experience with Uztelecom was good in most cities. The speed was strong enough for maps, browsing, messaging, bank apps, photo uploads, and normal work. I did not feel digitally blocked in daily use.
But coverage and speed are not the same thing.
The clearest example came near the Aral Sea. My Uztelecom connection had no usable signal there. At the same time, people using Ucell had much better connectivity.
That gave me a simple practical impression:
This is not a laboratory comparison. It is what I observed while actually moving through the country.
If your trip is mostly Tashkent, Samarkand, Bukhara, and Khiva, Uztelecom can work well. If your route includes Nukus, Moynaq, the Aral Sea region, remote roads, or longer off-city movement, I would seriously consider Ucell or at least ask locally before buying.
City coverage was generally good.
Train coverage was not.
The worst stretch I noticed was between Bukhara and the Urgench or Khiva direction. For three to four hours, the network could go from weak to unusable to completely absent. Sometimes the signal appeared briefly near stations, then disappeared again.
If you plan to work on trains, download everything before boarding:
Do not assume that a long train journey will have stable internet.
This is one of the most useful practical tips.
When your package expires, many small shops may prefer to sell you a new SIM card. That can be more profitable for them because a new connection includes the SIM cost, not only the data or validity.
If your SIM is still active, use Paynet.
Paynet machines are common across Uzbekistan. I noticed them near grocery stores and neighborhood shops. You choose the operator, enter your phone number, insert cash, and recharge.
This can save money because you are topping up the existing number instead of buying a new SIM card. The physical SIM itself may cost around 15,000 to 20,000 UZS as part of a new connection, so recharging is usually the cleaner option.
Almost everything I needed worked normally with an Uzbekistan SIM.
I was able to use:
My Indian banking and transaction flow worked fine. I did not face restrictions just because I was using a local Uzbekistan SIM.
Some subscriptions behaved differently because of geography. Services like YouTube Premium, Amazon Prime, or Netflix can show region-specific behavior when you travel. That is not really a SIM issue, but it is worth expecting.
Overall, Uzbekistan was easy digitally. The main risks were overpaying at the airport, ignoring phone registration, and assuming coverage would stay strong on trains or in remote areas.
If I were arriving in Uzbekistan again, I would do this:
The SIM itself is easy. The hidden lesson is the phone registration clock. Most tourists leave before it matters. I stayed long enough to learn why it does.
