Poor signals and speeds
They use wifi only because the speeds are shit and data throughput diabolical.
Cant OFCOM get it? Oh wait... its Ofcom we are talking about.
NeXt, they will come up with a survey, sayIng the country doesnt need 5G, since kids and 150,000 people only use wifi at home and minimal data. WIll play nicely into TELCOS HANDS TO not INVEST AND IMPROVE.
