Have got an iPhone 6 on vodafone, haven't been very happy with the coverage and not looking forward to another year with them. I was with Three before and was happy until my unlimited data became very slow, almost like it was being throttled....(I was using a lot of data) When the 6 came out the monthly costs were about £50 for three and £40 for vodafone, and it came with Spotify, so I thought I'd give it a try. I was naive enough to think that Vodafone, being a big network, would have good coverage. Vodafone seems to have fast 4G access, variable 3G service and no 2G internet access. At work I put my phone on windowsill and I was able to get internet access and texts, which was barable but not ideal. I fond vodafone and was told to try all the usual things, restart phone, change to 2G/3G, take out or replace Sim or change to different network and back to Vodafone. Nothing made much difference. recently the 3G network has stopped working , I switched to 2G (as advised) and I'm back to the 1990's, all I can do is call. Vodafone says its the nature of the coverage and I have to put up with it, I pointed out that my first iPhones never got a 3G signal and could access the internet happily if slowly but was told that todays smartphones demand mor data and time out and there is nothing they can do to help. I've been researching the cheapest SIM for an old MiFi to get internet, which seems a bit ridiculous.
