Re: I still don't understand
Exactly. I'd rather the networks would get around to finishing the upgrade to 3G, then 4G, before dumping them for 5G.
Good luck with that: 3G (UMTS) is due to be phased out in 2020. I think 2G will stick around for telephony because of its ubiquity. Technologically 5G is essentially an upgrade of 4G so deployment for the networks should be easier.
Most of the time I couldn't give a fig about 4G speeds, with the O2 network you can struggle for coverage even in the cities! The market needs opening up as there is now little or no competition.
