Tried multiple settings and worked with Consumer Cellular staff. (Consumer Cellular is an MVNO using AT&T.) I had this working with ZTE Open C (FFOS 1.3) after some experimentation. (I should have written down all of the settings before switching!) Right now I get a voice connection and Wi-Fi, but no data connection. Network shows as AT&T. Here are some suggested settings from Consumer Cellular: Name: Consumer Cellular APN: ccdata Proxy: Not Set Port: Not Set Username: Not Set Password: Not Set Server (If Available): http://mmsc.mobile.att.net MMSC: http://mmsc. mobile.att.net MMS Proxy: proxy.mobile.att.net MMS Port: 80 MCC: 310 MNC: 410 Authentication Type: PAP APN Type: default,mms,supl Bearer (If Available): Unspecified Another was CC LTE for Identifier My wife's Android Samsung Galaxy Nexus only has ccdata for APN and IPv4 set for data and roaming protocols. None of the other stuff. Thanks in advance for any help you can give me!
