Call waiting/call forwarding not supported on 4G?

[Anonymous]

I have just upgraded to 4G on O2 today, and noticed that call waiting was not longer operating.  When I try to re-enable there is Nokia message saying that "call settings don't work on 4G.  To switch them on, change the Highest connection speed in cellular settings."

Is this unique to my phone, O2, to the UK or is it a problem common to all Lumia 920s? 

It seems bizarre to offer a 4G phone that then takes away long established and very useful attributes.

at present 4g is data only you need a 3g / 2g connection for call settings until volte arrive later

Make sure your phone is not set to 4G only.

BTW how are you finding coverage?

Thanks.  It is just set to use 4G as the highest connection speed. 

Coverage is a bit patchy, and quite often it drops down to E.  However I get upload speed of 61.65 Mbps passing through Peckham Rye station this morning.

It seems that this is a glitch with the Nokia Lumia 920 and O2.  I have been to visit an O2 guru and we tried my sim in another 4G phone and call waiting worked on 4G and I have tried an EE 4G sim in my phone and call waiting works on 4G. 

So I am reverting to my old 3G tariff and at end of my contract in a month will probably get a n ew phone and maybe migrate to Vodafone, since they now have a better international calling package.
