I moved my O2 sim over and setup with no issues. A week later I changed my tariff with O2 to include 5G and was sent a new sim which I have now swapped to. I was checking to make sure all my settings for calls etc were the same and noticed I don’t seem to have an option for 4G calling / VoLTE. I had this on my old phone and sim. Not 100% sure if the option was ever there on the 13 with my old sim as I never checked. MyO2 says it’s enabled.&nbsp;<BR /><BR /></P><P>does anyone with an iPhone 13 see the option to enable/disable 4G calls/VoLTE in their mobile data options?</P><P>&nbsp;</P><P>thanks</P><P>&nbsp;</P><P>Graham</P><P>&nbsp;</P><P>graham</P> Thu, 07 Oct 2021 09:19:43 GMT https://community.o2.co.uk/t5/Apple/4G-Calling-iPhone-13-Pro-Max/m-p/1494580#M168120 GrahamR81 2021-10-07T09:19:43Z https://community.o2.co.uk/t5/Apple/4G-Calling-iPhone-13-Pro-Max/m-p/1494584#M168122 <P><a href="https://community.o2.co.uk/t5/user/viewprofilepage/user-id/3368534">@GrahamR81</a>&nbsp;</P><P>They will have missed the iData bolt on when you changed your tariff.</P><P>Call O2 to rectify <LI-PRODUCT title="Guide: Coronavirus Community Help and Support" id="Guide069"></LI-PRODUCT>&nbsp;</P> Thu, 07 Oct 2021 09:25:03 GMT https://community.o2.co.uk/t5/Apple/4G-Calling-iPhone-13-Pro-Max/m-p/1494584#M168122 MI5 2021-10-07T09:25:03Z
