A lot has changed since the PTT (now KPN) first set up the 2G GSM network in 1994. The 10kb/s connection of those days is by no means sufficient to meet our contemporary internet needs.
UMTS, also known as 3G, was the successor of 2G. Initially, the maximum speed 3G could reach, was 48kb/s. This was quickly boosted to a maximum of 256kb/s. The upload speeds reached were 48kb/s at most. Almost all 3G antennas in the Netherlands are in the 2100 MHz frequency band. The penetration strength of this high frequency is moderate. The disadvantage to this is that coverage is poor, especially indoors, in forests and in urban areas.
