    Default AT&T HTC One on T-Mobile issues

    I was forced to switch my carrier from att to T-Mobile. I have an factory unlocked att HTC one. When I put my new tmobile SIM in the voice works but the data doesn't even though the screen displays 4g at the top. I messed around with all the settings at #*#*info*#*# and it still doesnt work. In setting, mobile data says it is disconnected when not connected to wifi, when connected to wifi it says that it will use network date when WiFi unavailable.

    I have looked through this forum for answers but cannot find anything with this issue. Any help is greatly appreciated.

    Make sure your APN is set to fast.t-mobile.com. I've attached a screenshot. You can access APN settings here: Settings>Mobile data>Access point names. Make sure to select "Save" when you're done editing. I don't use MMS, so that info in the screenshots is probably not correct.

    We are travelling internationally and my husband had this problem on his HTC One M9.

    Settings>Mobile Data>Access Point Names
    Create a new apn by tapping/selecting the three vertical dots in the upper right corner
    Choose New apn
    Manually enter this data:
    Name: T-Mobile GPRS
    APN: fast.t-mobile.com
    MMSC: http://mms.msg.eng.t-mobile.com/mms/wapenc
    APN type: default,supl,mms
    Everything else can remain unselected/unchanged

    My HTC One M8 phone was working fine but my husband's M9 wasn't. I saw my APN was different than his, so I manually created this APN based on mine and his data started working perfectly.

    Best of luck!
