Three is the best network cus its cheaper? u pay for what you get......its a crap network......far less network coverage then others.....yes when 5g is working on three it works well but so do others..
I have to say 02 has got really bad ! 4G signal is most areas and its just so so slow ! Just got duel sim with EE and its so good 5g and 4g works everywhere I go!
The best network for speed is Three because they have more 5G bandwidth than any other network. but other operators have more extensive 5G coverage. however, most 5G networks in the UK are 'non standalone' which means they are actually based on older 4G infrastructure
I find that 3 has better 5G coverage than their map shows and their download speed is higher than EE in good signal. Instead they have slower 4G speeds compared to EE. Overall I find EE more balanced in terms of speed/coverage because in poor signal 1-2 bars, 3 tends to have low download speeds.
