    Hi guys.

    So I have the AT&T iPhone 4S 16GB, and I am a unlimited data plan carrier.
    I enjoyed my device until end of January where my data connections have been really slow.

    Its not always. This is the problem.
    It gets slow for a while, literally giving me no access to internet, map, and even using the speedtest app.

    But then it gets all better again. Starts off around 92ping, 0.35 mbps down, 0.21 mbps up.
    Then it gets better a bit and goes up to 1.2 mbps.
    When its acting good, it becomes near to 4 mbps.
    As you can see, its definitely a problem.
    Yes, I do have all bars on what they like to call the "4G".
    And yes, its not the location.

    My friend's iPhone acts fine and I tested in many civilized places like SFO Airport, LA, etc.

    Im starting to think that this might be because I am the old unlimited data carrier.
    I do use a lot of internet since I render Maps, open safari's, update apps, etc.

    Do you guys think this is the problem?
    Or can this be the iPhone's problem? i.e. antenna failure, case fault, ....

    Thanks in advance.

    It has nothing to do with the unlimited data plan. It has to do with AT&T's network. Some places or times it will be congested and get very slow data speeds and other places or times will be better.

    AT&T can also throttle fairly severely after you go over 3GB (they don't always in my experience). It's fairly easy to do on HSPA+ ("4G").

    My friends iPhone and my fathers iPhone (both AT&T) were fine tested at the same location and time.

    However, Im the only unlimited data plan carrier so I thought they sowed my internet down.

    Reset the network settings on your iPhone. I find that usually fixes these issues.

    Unless they throttle you it should be the same.
    Tests do vary, you can get 0.5mbps now and a few seconds later at the same exact place get 4-5mbps.

    Seems either they are slowing you down or your Iphone has a problem
