How to choose an internet provider: a practical guide
The question "which is the best internet provider" has no universal answer. The best provider is the one that actually works at your specific address, offers technology suitable for what you do with the connection at a reasonable price, and has a contract without unpleasant surprises. National rankings and comparison tools cannot assess this - they work with marketing lists, not real coverage at the address point level. The following procedure goes the other way: from availability to choice.
Step 1: find out who is actually at the address
Before you start comparing price lists, verify which internet providers actually offer service at your address. Large comparison sites often show only ISPs that have a commercial relationship with the given portal (they pay for their ranking position), local wireless networks, smaller fibre operators or municipal networks are typically missing, even though they operate in the street. The catalogue on katalogisp.cz works directly with data from the Czech Telecommunication Office (ČTÚ), so it includes these smaller players in the results. Simply enter your address into the search on the homepage.
Step 2: compare technologies, not just tariff names
More than one technology may be available at a single address, each with different features:
- Fibre (FTTH/FTTB) - the highest and most stable speeds, now standard where available. More in the article about fibre internet.
- Metallic networks and cable networks (xDSL, coaxial) - speed depends heavily on distance from the cabinet or on sharing capacity with other users.
- Wireless networks (FWA), typically from smaller local ISPs - speed and stability depend on line of sight to the transmitter and weather conditions.
- Mobile connections and satellite - solutions mainly for areas where no fixed network reaches.
Technology alone does not determine which offer is "better"; it determines what to realistically expect from the connection. The catalogue displays a technology badge for each internet provider, allowing for an immediate comparison.
Step 3: speed vs. price - what you really need
A higher advertised speed does not automatically mean a better choice if you do not use it. A household that streams video and works from home needs different parameters than an individual who uses the internet mainly for email and browsing. Before you decide, read what the numbers in offers actually mean - this is explained in the article Internet speed: what the numbers in offers mean. You can check the current speed of your existing connection at any time in the speed test.
Step 4: read the contract, not just the price list
When reviewing a contract, there are several things to consider:
- Is the price after the promotional period the same, or does it increase after a few months?
- What is the notice period and what happens if you want to leave earlier?
- Is installation included in the price, or is it charged separately?
- Is there a guaranteed minimum speed or just 'up to' speed?
If you plan to change your internet provider in the future, the procedure and your rights are described in the article How to change your internet provider.
Step 5: compare multiple offers at once
In most addresses in the Czech Republic more than one internet provider is available. A complete overview of all companies registered with the Czech Telecommunication Office (ČTÚ), including smaller ones, can be found in the catalogue of providers, where filtering by region and service type is possible.
Common mistakes when choosing
A few recurring situations worth checking in advance:
- Deciding based on just one comparison tool. If the portal shows only a few offers, it does not necessarily mean that no other options are available at the address; it may simply indicate that other internet providers do not have a business relationship with that portal.
- Underestimating installation. The lowest monthly price sometimes hides a higher one-off setup fee or the need to buy your own end device.
- Browsing local internet providers. Smaller regional or municipal networks are often well established in the given locality, have a fast response to faults and often a competitive price - only they were not worth hearing about because they do not advertise nationwide.
- Signing the contract without a technician verifying the address. With newer technologies (mainly fibre), it happens that the recorded availability at an address still requires physical verification on site - it is worth asking the provider in advance about this.
Summary
The best approach is simple: first check the actual availability at the address, then compare technologies and their features, and only afterwards consider price and contract terms. If you reverse the order and start with price, you may easily end up with an offer that no one can activate at your home.
