Hi Nikolae, welcome here! Unfortunately there is no way to increase the speed of the unlimited "Onbeperkt Online" or "Zorgeloos Online" bundles. You can order faster bundles, see Prepaid bundels: extra voordelig bellen, sms'en en internetten | KPN. They have a data limit of 1GB or 100MB. The unlimited bundle is intended for light internet use and not suitable for downloading or streaming.



If you only need fast internet some of the time you could consider the "Dagbundel 1GB" which is valid for a day and does offer a faster download speed with a 1GB data cap.
