Calls not received. Texts delayed.

[justinleon2113]

Hello. Just upgraded to the ZenFone 6 (Edition 30) over the new year and notice that many calls from family and friends are going straight to voicemail. I tested this with a friend in the room, and out of 5 attempts, only 3 made the phone ring. Many important calls for business do not ring at all. I am using Ultra Mobile (T-Mobile MVNO) and have done the usual run-around (reset phone, empty cache, check all settings for fowarding, DND, and such). Even on a fresh install, it is experiencing the same phenomenon. I tried a different phone and it seemed to consistently work...I'll keep testing.
I wanted to see if anyone else had issues with not getting calls or texts (irrespective of carrier) or if it could be just carrier issues for me. I have great coverage in my area, thus it is not like I am roaming or disconnected. Thank you for the help.

I've been having the same problem but very sporadic. At first I thought I just missed the call but I can confirm I have now witnessed calls going directly to voice mail. I have also seen text messages delayed a few hours. This again is very sporadic. The phone calls may be 1 in 8 and the texts may be 1 in 25. This goes back to at least 2 updates. Cannot be more precise than that.
If you need additional help with logs, please let me know.

I had the Zenfone 5z and currently have the Zenfone 6. Both on T-Mobile ...Both phones have the same issue. Calls at times go straight to voicemail.

my phone has this problem too. sometimes calls go directly to vm, phone doesn't ring at all and nothing in the call logs that a call came in. and some messages delayed by as much as a few hours. I'm running the latest update on Android 10 on t-mobile.

I've only gotten one set of logs so far.
Anybody else willing to help us diagnose this problem?
