Not only because of many interesting attractions like Palace of Culture and Science, Wilanów Palace or Łazienki Park. Warsaw is currently one of the most important business places not only in Poland, but also in Europe. For making sure that every deal with a company will be successful, you will need a well Internet connection. Here are some information about how to connect with Internet after arriving to Warsaw.

In Poland there is a possibility to buy a SIM card of Polish mobile operator (like Orange, Nju Mobile etc. ) and use it by inserting it in your phone’s SIM card slot. It is available in most supermarkets in Warsaw and in many local newspaper stores. Sounds simple? Unfortunately since February 2017 you also have to register your temporary card after buying it with your all ID data which can you make feel invigilated.
 

SIM Card Registration Requirements

 

If you decide to purchase a local SIM card in Poland, keep in mind that SIM card registration is mandatory under Polish law.
 

For most international visitors, a valid passport is required to register a prepaid SIM card. The registration process is usually completed in just a few minutes at an official mobile operator store or an authorized retailer.
 

If you plan to sign up for a postpaid (contract) mobile plan, additional verification is often required. In many cases, providers will ask for a Polish PESEL number (the national identification number), along with proof of identity and, depending on the operator, proof of residence or other supporting documents.
 

For short-term tourists, a prepaid SIM card is generally the easiest option. However, if you want to avoid registration altogether, an eSIM can usually be purchased online before your trip and activated digitally, allowing you to connect to mobile data as soon as you arrive in Poland.

Hot spots

Because of many tourists and local visitors, many cities decides to place hot spots in most popular places. You don’t need to pay for them, sometimes only you have to know password (mainly in restaurants or café, just ask a waiter for it).

But you are depended on a place, where the hot spot is. The range is often not enough strong to reach the Internet. Websites while using a local router (which shares Internet to even several dozen of people) could be loading very slowly, so if you are not patient, forget about public hot spots.

Mobile Internet Speeds and Coverage in Warsaw (2026)

 

Warsaw continues to offer some of the fastest mobile internet in Central Europe, making it an excellent destination for travelers, remote workers, and business users who rely on stable connectivity.
 

According to Q2 2026 network performance data, the average mobile internet download speed in Warsaw reached 204.1 Mbps, while the average upload speed was 31.5 Mbps. Average network latency (ping) measured 21 ms, providing a responsive connection suitable for video conferencing, cloud applications, online gaming, and HD streaming.
 

The city benefits from extensive 4G LTE and 5G coverage across most districts. In central areas such as Śródmieście, Wola, Mokotów, and parts of Praga, users connected to well-optimized 5G networks can experience download speeds exceeding 300 Mbps under favorable network conditions. However, actual 5G performance varies depending on the operator, device compatibility, network congestion, and distance from the nearest base station. In everyday use, typical real-world 5G speeds generally range between 40 and 100 Mbps, which is still more than sufficient for video calls, navigation, streaming, social media, and remote work.
 

Whether you choose an eSIM, a local SIM card, or your domestic operator's roaming service, Warsaw's modern mobile infrastructure provides fast and reliable internet access throughout the city. To achieve the best possible performance, it is worth selecting a provider with strong 5G coverage in the areas where you plan to spend most of your time.
 

Roaming fees

The last possibility to connecting the Internet in Warsaw is using a roaming in your mobile phone. The easiness of usage this possibility could make it best way to communicate with the world. By turning on mobile Internet connection you will already have access to your web browser, e-mail any apps which you need them in online mode (like Spotify without premium version).

However, the fees for each 100KB of Internet transfer used through roaming are very high which makes this option not feasibly for an Youtube users or for making international business contacts in Poland. Remember to use mobile roaming reasonably, mainly in very important moments.

All things considered, there are many ways to achieve an Internet connection in Warsaw, so you don’t have to worry. Some solutions could be very simple to use along, but their price of usage could be very high. Using Polish WiFi is really easy and cheap, so this could be the most reasonable idea when you are going the Polish capital soon.
 

• Understanding Roam Like at Home (RLAH)

If you're traveling to Warsaw from another EU or European Economic Area (EEA) country, roaming may not be as expensive as many travelers expect. Thanks to the Roam Like at Home (RLAH) regulations, you can usually use your domestic mobile plan while traveling within the EU/EEA without paying additional roaming charges.
 

Under RLAH, calls, text messages, and mobile data are charged the same as they are at home, provided you use your phone for normal travel purposes. However, mobile operators apply a Fair Use Policy (FUP) to prevent permanent roaming. This means your data allowance while abroad may be lower than your domestic unlimited or high-volume plan, and exceeding the fair use limit may result in a small surcharge.
 

For most short-term visits to Poland, RLAH provides a convenient and cost-effective solution, especially if your existing plan includes a sufficient amount of roaming data.
 

Travelers from outside the EU/EEA, however, are generally not covered by RLAH regulations. International roaming charges can be significantly higher, particularly for mobile data, with costs varying depending on your home operator and destination. Before traveling, check your provider's roaming rates or consider alternatives such as an eSIM, a local SIM card, or a portable WiFi router to avoid unexpectedly high mobile bills.
