    Default Phone Dropping Data Connection AT&T

    I have noticed that sometimes after I turn wifi off, my HSPA+ connection hops in and out every few seconds. It turns from white with an H to no H then blue with an H then no H, etc.

    Any ideas? A reboot fixes it, but still...

    What APN settings are you using, and what data plan you have

    I've noticed a couple of issues but not sure if they're related or not. I often notice, without moving the phone much, the signal will fluctuate greatly especially when coverage is moderate. It will go from about three bars to no coverage without moving. All to often I'll be sending a text message with android warning me that there is no network coverage when I had good coverage just a second ago. Sometimes after turning off, or leaving, WiFi coverage I notice that the signal bar will constantly cycle from grey to h/grey to h/blue then back to grey and do that constantly until i reboot the phone.

    You guys should try deleting the other apns you have in the phone so you only have one in there

    I had it happen once and I either toggled Airplane mode or rebooted and it was fixed. ST AT&T.

    I'm not convinced that the display showing network reception is calibrated accurately. Mine fluctuates quite a bit too (though edge, which I leave it on often as a battery saver, is always really consistent). Also, The other day this happened. : Phone Dropping Data Connection AT&T-uploadfromtaptalk1355402305587.jpg

    I know having network reception without data is possible, but I didn't think you could receive data without *network* reception. I'm on TmO post-paid BTW.

    Once you have the correct APN setting for your phone, and data plan you should be good.

    I've noticed they all vary depending on what plan you have, or really which phone you had prior to the Nexus 4. If you let me know what plan, or phone you previously had, I can better help you out.

    The gray signal indicator with no bars does not indicate no service / no reception. It just indicates a very weak signal (for example, -111dBm).

    The signal indicator turns black for no service.

    I switched from Sprint, so my previous info wouldn't matter. I'm using ST-AT&T. I have a very weak cell signal at my house, but once I get out of my neighborhood, it's pretty good. I chose AT&T because their cell service is better to places that I travel to than T-Mo. What APN settings should I be using?

    I would try the following:
    Name: ATT
    APN: wap.cingular
    Proxy: blank
    Port: blank
    Unsername:
    Password: blank
    Server: blank
    MMSC:
    MMS proxy: wireless.cingular.com
    MMS Port: 80
    MCC: 310
    MNC: 410
    Authentation Type: blank
    APN Type: default,supl,mms
    APN Protocol: IPv4
    APN roaming protocol
    APN enable/disable checked and grayed
    out on my phone
    Bearer: unspecified.

    There a few other ones depending on your plan, but this seems to be the most common one.

    Losing data intermittenly on ST AT&T is a known issue and has been going on since about the middle of summer. It is one of the major reasons that I switched to using ST Tmobile as my primary service when I picked up my N4. The oddest thing about it all is that some areas suffer from it much more than others and some areas don't seem to have the problem much at all.

    Those are almost the exact settings for AT&T. These will work on Straight Talk?

    Well, I'm on wifi at home, but because the network connection is so crappy, I can't send/receive texts or mms messages most of the time. I have to walk around to certain locations in my house in order to get a signal.

    I'm sure this has been asked many times, but I'm new to Android and don't even know how to begin to search for an answer to my question.
    I have an iPhone 4s with AT&T, smart phone unlimited data plan. I gather I'll need a new SIM card; will I have to change the APN? (Not that I even k ow what that is!)

    Text messages don't use data so your data connection isn't the problem as far as texts go. What's your signal like when you are having issues with texts?

    Like I said in a previous message, my cell signal is crap at my house. When it does show I have service, it's usually in the -113 ~ -107 range.

    I am using the WAP APN from at&t after having this issue with the hspa APN floating around the forums. WAP still gives me 4 to 9 Mbps down and it never drops. I'm using a 4G data plan as well.
