  • Pixel 4a ATT Calls just say call ended

jahtripper have you got LTE only mode on? If you do type in *#*#4636#*#* into the Dialer then select Phone Info followed by checking that the VoLTE provisioned toggle is set to the ON position. If not you will need to contact your carrier to have it provisioned.

Yeah unfortunately it shows its toggled on. I dropped the sim back in my samsung. Not sure but this build and actual device worked with my previous carrier straight talk.

    jahtripper Go to Settings -> About phone -> Model and find the Hardware SKU.
    You may have an International or Japan model which AT&T does not officially support.
    G025J is the NA model for the Pixel 4a and is what works on AT&T.

    jahtripper have you got LTE only mode on? If yes have you tried changing the setting to LTE recommended?

    jahtripper Does this problem occur on a fresh factory reset device?

    What did you change your APN settings to? I can tell you right now if you added "IMS" to anything, that's your issue. AT&T doesn't play well with any adjustment to that.

    If you could, would you mind trying to create a new APN with the following:

    Name: whatever
    APN: nxtgenphone

    Skip the mmsc/proxy/port for now

    APN type: default,mms,supl,hipri

    IPV4 for both regular and roaming

    Mvno type: GID if you have their elite data packages, otherwise IMSI.

    Save apn, select it, restart your phone.

    Try that, if that doesn't work-- you have two options.. Factory reset, power off for 5-10m, turn on and test.

    If THAT fails... Bother att incessantly and get comped for your time.

    I had had same problem saying call ended, tried everything, what fixed it was going into sim settings and switching off (4G Calling), if that doesn't work try also toggling between 3g, 4g, 4g only and 5g.
