    I just switched to AT&T and can not send a text even with 3 bars of signal (4G LTE). I had the same issue with the S4, but on verizon network.

    I can have my galaxy note 4 next to this phone and send text after text. What do i do?

    SMS text messaging doesn't use data. Check your settings: Go to phone settings —> more… —>mobile networks —>Access Point Names

    From what I am seeing, for AT&T your setting should be (but check with AT&T to make sure. I am on T-Mobile):

    Name: ATT Phone
    APN: phone
    Proxy: Not set
    Port: Not set
    Username: Not set
    Password: Not set
    Server: Not set
    MMSC: 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,supl
    APN protocol: IPv4
    APN roaming protocol: IPv4
    Bearer: Unspecified
    Mobile Virtual network operator: Not set
