I suspect 5g with the data required to run a house would cost more than the average phone bill tbh.4G or 5G would do wouldn't it?
For me this whole thing doesn't pass the reality sniff test tbh. Ultimately it's saying that a recent graduate earns £xx, therefore can not afford average living costs. But that seems reasonable to me, I'd expect the average graduate salary to be less than the median salary. Why would someone expect to earn a median salary when they have a bit of paper that says they have an academic qualification but have limited experience outside of that?
