Volte and Wifi Calling One Plus 5

[dby332]

I purchased a OnePlus 5 from o2 directly a few months ago and used it with an EE sim. With that there was an option in "sim & network" settings that  you could slide the on/off for 4g calling and wifi calling. A little symbol appeared on the top of the phone alongside the usual icons that said VoLTE.  I have since moved from EE and joined o2 but there are no options under sim & network to turn on wifi calling and 4g calling anymore which seems very strange because those settings are in that phone and it is capable of this feature so can't understand where they have now gone. I have logged into my o2 and under device info activated the 4g and wifi calling and it says it is active on my line. I know oneplus 5 is not an o2 branded phone but as this handset is compatible for these services it seems strange that the options no longer appear, is there some other setting that is hidden with o2 that needs turning on as I'm not sure how to get the Volte symbol back and currently when making calls it drops from 4g to H+ then back to 4g after calls. It's not a great hardship but when it worked with a EE sim it seems funny that it doesn't on o2 when they have the service the same as EE does and 4g calling is available in my area and surrounding postcode areas.

Definitely Oneplus 5 not 5T? The list at https://www.o2.co.uk/connectivity/wifi-and-4g-calling currently shows the 5T but not the 5, and I've had the 8.1 firmware for a few weeks but still don't have VoLTE / VoWifi options in the operator settings menu 😞

Have you enabled it in the device settings of your MyO2 ?

MyO2 doesn't work for me (small business SIM), I'd already talked to customer services a while back and they promised me they'd provisioned my account for VoLTE, but given what you suggested here I rang today and despite what I'd been told it hadn't been done. Now can confirm VoLTE working on the 8.1 update on the OnePlus 5, thanks
