And let's be honest, when that emblem in the top corner of our phone turns from 4G to "E" or "GPRS", our hearts sigh. "How can it be there is no coverage when I'm in the middle of the nation's capital," is an oft-heard cry.
But today, Ofcom, the UK's telecoms regulator, gave its definitive opinion on how the nation's four main operators – EE, O2, Three and Vodafone – stack up in London when it comes to 4G mobile broadband and voice services.
Making the grade
Ofcom kicked off by looking at the proportion of the time operators could achieve a minimum download speed of 2Mbit/s.
The regulator picked this minimum because "such speeds are likely to be sufficient to support high-capacity video services".

I feel the need... the need for speed
Also under review was which network had the fastest average download speed. The Ofcom results were pretty decisive, with EE nearly four times the average download speed of fourth place O2
Just load, dammit
EE delivered once again as the firm came out on top for successful loading of some of Britain's best-loved web pages.
It's pretty definitive
Indeed it is. EE have topped the charts by some distance. Mr Bacon and his promises – how could we ever have thought he'd let us down?
Nevertheless, this is only London. So what about the rest of our green and pleasant land? Rather boringly, it is a very similar picture in terms of ranking. However, Three does close the gap to joint second place with Vodafone on average download speeds.
