    Welcome to Android Central! That G3 is the international version, and according to these specs, isn't compatible with the AT&T LTE bands:

    LG G3 D855 International 32GB Smartphone G3-D855-32GB-BLACK B&H

    However, it should be compatible with HSPA+. Are you getting that connection?

    Also, make sure your APN settings are correct: Programming non-AT&T devices with the correct APN and MMS data settings- AT&T Wireless Support

    Your APN is probably wrong. I'll post the settings. You have to remove the spaces in the MMS and Proxy settings. If I leave the spaces out, it won't let me post it here because it sees it as a link and I can't post links yet.

    Here:

    APN = phone
    MMSC = http: / / mmcs. mobile, att. net (remove the spaces)
    MMS proxy = proxy. mobile. att. net (remove the spaces)
    MMS port = 80
    MCC = 310
    MNC = 410
    APN type - default,mms,supl,hipri
    APN protocol = IPv4
    APN roaming protocol - IPv4
