    As the title says. Do I need to go see AT&T, or is there a setting I can check? I can dial 611, but can't dial any other number. I first plugged in the SIM into my iPhone 6+ and it worked fine, but after switching it to my LG G4, no good. I've rebooted several times to no avail.

    One problem is that iPhone uses nano Sim and LG G4 uses micro Sim. So unless you are using a Sim adapter it is unlikely the nano Sim will work.

    Bring it in to AT&T. Since the phone can dial a number, it's working, so the problem may be with your account setup.

    Called them and found out it was an APN issue. (Yup. I have a SIM adaptor for the Nano. I ordered a Nano so I could test the iPhone and G4 together.)

    When I first stuck the SIM card in, the only phone number I could call was 611. After setting up the APN, I can now use the phone and surf, so...

    In case anyone else has an issue, here's what you need to do to fix it:

    Settings/Mobile data/Menu(Top 3 dots)/Mobile Networks/Access point names/Menu again/New APN
    Name: ATT Phone
    APN: phone
    Proxy: Not Set
    Port: Not Set
    Username: Not Set
    Password: Not Set
    MMC: http:\\mmsc.mobile.att.net
    MMS Proxy: proxy.mobile.att.net
    MMS port: 80
    MCC: 310
    MNC: 410
    Authentication Type: None
    APN Type: default,mms,fupi,hipri
    APN protocol: IPv4
    APN roaming protocol: IPv4

    Save, then select.
    Lastly Reboot.
    After the reboot, it should be working now.

    Also, the AT&T guy did say they had to do something to my account on their end, so if setting up the APN still doesn't work, then you'll have to call them. Keep in mind, you're probably going to get the same message I got, "Sir (or ma'am if you're female) we don't support non-AT&T phones, but let's see if setting up an APN will work. If not, then the phone won't work on our network."

    Does it show LTE at the signal bars, or does it show 4G?

    The H815 version he has like mine only shows 4G. US Carrier models would only show LTE. Both are high speed data btw.

    This is the International version. It only shows 4G. From what I've read, it still gets the LTEish speeds. I don't know that for sure though. I am getting 30-40 Mbps in the DFW metroplex. It's just that AT&T doesn't work well in Sanger.
