Prague and the Czech Republic are well-wired and covered Wi-fi hot spots. Most hotels, including hostels, offer it free of charge to guests, though occasionally more expensive properties charge extra for this service. Additionally, a growing number of bars, cafes and restaurants offer free wi-fi, which is usually marked on the door with the international wi-fi sign.
The most convenient and reliable places to get wi-fi access in a pinch are McDonald’s and KFC restaurants, which offer free wi-fi around the whole Czech Republic. And of course, not to forget coffee chains like Starbucks, they also offer free WiFi with any coffee purchase.
Mobile 4G/5G Internet
You can get connected to the internet via your mobile operator as well, depending on your tariff and roaming access (using 4G/HSDPA/5G). If you are staying longer, it is worth buying a local sim card and arranging some tariff for mobile broadband. Connection, especially in Prague and other large cities, is fast and very reliable. Consider Mobile prepaid internet from T-Mobile, o2 or Vodafone. This gives you unlimited access to the internet for around 500 to 800 CZK monthly (offers vary). It is also possible to activate only a one-day internet package, paying around 3o to 50 CZK per one day of internet access. No contract is required; buy a prepaid sim card pack or ask staff for assistance.
