Sub-GHz frequencies are radio waves with physical properties that provide high area coverage and good indoor propagation of 5G. Thus, since the Galaxy A51 5G cannot use these frequencies on the O2 5G network, you should expect significantly worse 5G coverage, especially in rural areas and inside of buildings.
Lastly, mmWave bands are not understood by the Galaxy A51 5G. Thus, you may never experience download speeds faster than 1 Gbps on this network, even though the O2 5G network is capable of delivering even higher speeds at certain locations. The lack of mmWave bands should be no issue in usual everydays situations. However, it might turn into a problem when visiting large events in stadiums or other overcrowded areas in metropolitan cities.
