I've been on the old iPhone unlimited tariff for the last 4 years. I would've thought that they'd allow a 4G bolt-on for £5 but cap the 4G data to a certain amount. Once you hit the cap, your data switches to 3G (unlimited). If their 4G network is that fast, high users will soon want to switch to a newer tariff. For those who don't use vasts amount of data, they benefit from 4G speeds and O2 gets another £5 per month.
I only want to try O2's 4G network and won't sign up to a 12 month tariff or risk losing my current tariff just to try. I'm not that impressed with their 3G which I think has got worse over the last two years so 4G was O2's last option to keep me. Instead, O2 now lose me as a customer to either EE or Three. PAC obtained. Just need to decide which network.
