3G phones.

EE told me last year that they are switching off the 3G network and that I'd need to upgrade my current very old pay as you go SIM to a new one to be able to access the internet. The problem is that that would put me onto a data subscription basically, meaning that I'd have to top up by £10 every month.

Well I've just accepted that I'll not be able to get on the net when out and about, I can still make a call and text though.
I've heard that the whole railway network runs on 2 or 3G and would take years to upgrade it?
Does that mean that we don't need to panic about being cut off any time soon?
