    Problem solving time:

    I have a T-Mobile Note 2 with CM 10.2.1 (Android 4.3) and I've been really happy with it. I work from home, so most of my data use is over wifi. While running some errands a couple of days ago, I noticed I'm no longer getting data while not on wifi. I can get full bars or close to it, but showing as the inactive white, not the active blue of Android 4.3. So, there is signal. A friend's stock Nexus 5, also on T-Mo, isn't having the same issue. And phone calls seem to be unaffected. So, here are my mostly novice questions:

    1) Are there any settings I should check?

    2) If the settings are all OK, are there any apps that might cause issues? Which ones?

    3) If it's hardware, what kind of repair cost am I looking at, if I wanted to repair instead of replace?

    And the answer is....

    Well, maybe. #1 seems to be the culprit. APN to be precise. The phone has 5 APN presets. One each for Simple Mobile and StraightTalk T-Mo. The other three are native T-Mo.

    a) epc.t-mobile.com seems to favor edge settings,

    b) fast.t-mobile.com favors LTE

    c) there's also an IPv6 fast.t-mobile.com

    My phone was on epc, so I played with the choices. That and the IPv6 setting struggle and give up. The regular LTE setting works like a champ. So, if anyone has a similar issue, it looks like APN is the first thing to check.

    Option B worked for me. But, I have an unlocked AT&T Note 2 and use Tmo sim and changed APN to option B. Also, make sure Preferred Network Type is set to LTE

    Yup. That's the one that works for me, too.
