    Hi,

    I LOVE my nexus 4, but it keeps dropping the HSPA+/HSPA data connection when I am in a phone call. It has the SIM from a One X. I called AT&T and changed my plan back to the compatible HSPA+ unlimited. Does it need a different SIM?

    Any ideas would be great!
    APN I am using:

    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: not set
    APN Type: defualt,supl,mms,dun,hipri
    Apn Protocol: ipv4
    APN roaming protocol: ipv4
    Bearer: unspecified

    Thanks!

    If you read the thread it's about AT&T, not T-Mobile.
