Highest connection speed - grayed out

[Nick_1020]

In Settings -> Mobile Network - Highest connection speed setting is grayed out and the option shows as 3G.

Is this a restriction by my carrier (3 UK) or that 4G isn't available where I currently am?

Thanks.

Must be a restriction by your carrier and/or your sim card does not support 4G. The phone, itself, supports 4G.

It turns out my carrier wasn't being entirely upfront with me. They do not, at present, have a 4G network in place. They didn't mention this at any time during the upgrade so I feel the contract has been mis-sold somewhat. They're investigating this but there's not much I can do. It looks like they will have 4G ready to go in a few months so I may as well wait.
