Hi @Anonymous Have a look at this self help thread http://community.o2.co.uk/t5/Pay-Monthly-and-Pay-Go/Self-help-guide-Is-the-network-down-for-me-or-everyone/m-p/593752#M59833

Also try resetting your network settings and rebooting the phone

Could be a sim card error.
If the above doesn't fix it try a sim swap and also make sure your network selection is set on Auto.

I find my iPhone 6 tends to prefer 2g if 3g is weak, read somewhere that its to do with O2 and the iPhone's way of handling the signal? Someone correct me if I'm wrong!

Phones should always seek out the fastest signal regardless of strength but they will lock onto a very strong slower signal if the next fastest is too congested.

When I was with O2, I used to often see this happen and I would quite often need to toggle Airplane mode on and off for to get 3G again. It used to happen often when I ended a call. It would hang on GPRS (2G) till I toggled Airplane mode on and off or would take an age to pick up 3G again.

But since I moved network, I don't get the above two issues now. I would say its more a network issue rather than the way the iPhone handles the signal. I also used the same iPhone on both O2 and the network I moved to, so it isn't a particular quirk with the iPhone I have.
