hi all. not sure if this has been asked before but whenever i make or receive a call, my data connection 4G+ symbol changes to H+. so it looks like my 4g data connection drops to 3g when I'm on a call. is this supposed to happen? i sometimes have long call meetings where i need to also be on the web and I'm wondering if my data speed is dropping.

thanks

    I'm on t-mobile in the us and from what i understand they do support volte. not sure about 4g+ tho. I'm not even sure what 4g+ is lol. i thought it was 4g advanced lte but when i do speed tests i find 4g is faster than 4g+ lol.

    If you don't have a VoLTE support, when you make a call you can't maintain the 4G connection. So you drop to H+.

    I'm not sure but maybe your career enables VoLTE but Zenfone 6 doesn't integrate it at this time ...

    hmmm ok thanks for the info. I've been having bad call quality when using the built in mic (wired and Bluetooth headphones work ok) and was just wondering if dropping to h+ had anything to do with it. thanks again.

    Unfortunately the issue is the phone, not T-Mobile. Numerous threads on here begging for voLTE in the US. No help likely, it seems, as the phone is 1 year old now. They seem to only be adding it elsewhere. I bought my wife a Zenfone 5 at the same time I got the 6 and it doesn't have voLTE on T-Mobile either. It is apparently possible to enable but requires unlocking the bootloader and rooting the phone to edit the mbn of the phone. Seemingly a simple change that Asus could do on their own but they apparently have reasons not to do so. I'll never buy another phone without voLTE to avoid enabling such products. Otherwise it's almost a perfect phone for me.

    agreed. when the phone works it's great. speed, battery life, camera all work nicely on my phone. I also appreciate the timely updates. too bad the things I really need aren't working the way they should.

    I agree. ZF6 is perfect phone for me too, but disabled VoLTE/VoWiFi eliminates all its benefits. Especially in Corona-crisis time.
