I've been having a problem with data on my iphone 4s.  More often than not, when i have at least three bars, the data speed is extremely slow.  Safari, facebook, foursquare, etc run very slow and sometimes time out because it can't find a connection.  Does anyone else have this issue, or should I be taking it into the apple store?


iPhone 4S, iOS 5.0.1

    First try resetting your network settings by going "Settings>General>Reset>Reset Network Settings. Possibly take out the SIM card and ensure that it is properly sitting in the tray, wipe it off, and put it back in.

    Hey brett143 - could you tell us where you live and which cell phone company you're with?

    Sorry, I should have mentioned that. I'm in Chicago using AT&T.

    As a reply to your conditions with carrier and location, typically AT&T's network is pretty fast, so if you follow the troubleshooting I previously stated, you might have some luck.

    Ive always read that At&ts data speeds were the fastest, especially in Chicago, so I was surprised that it's been run ing so slow. I'll try resetting the network and taking out the sim card. Thanks for the suggestions!

    I'll be very interested to hear about your experience - the few times I've visited Chicago, I've had a terrible time getting a data connection in the areas that are densely populated. Suburbs were OK, but downtown I couldn't use my phone for anything but making calls and maybe sending texts. I had full signal, and that didn't help.

     

    I'm currently in Wauwatosa, WI, and my iPhone struggles if I'm traveling during rush hour.

     

    I have an iPhone 4 with AT&T, for reference.

    Are you still having this issue? I noticed this same thing starting about 4-6 weeks ago. It is actually to the point where if my phone is not on wifi, I can't use any data (which would include sending iMessages or checking e-mail). It has basically turned my phone into a computer that needs wifi at all times, so thats how i have been using it this past month. The odd part is I just got a text from ATT saying i am in the top 5% of data users this past month, which doesn't make any sense to me since i have been using wifi more than ever. and basically unable to use data. It makes me think there is a problem with the phone, continually searching for data and not able to connect? I am in Chicago, using a 4S on ATT.

    Yep - still having issues.  I'm just boiling it down to the fact that I'm in the loop and there's a lot of "electronic congestion."

    I am also having this problem, I find that at home on wifi everything is great.  The minute I leave home and it goes to 3g regardless of how many bars I cannot connect at all, it times out and tells me to check network.  The only thing I have found so far is that when I turn the phone off and back on as long as 3g hooks up first it will then work fine and fast.  It seems like an issue switching from one to the other.  I'm getting tired of turning my phone on and off to fix this!

    I'm in South Florida and have the same exact issues! I have called ATT a million times to question why such slow data and they can't figure out why.  So now every month my data is horrible, I make them give me a discount because I am not paying full price for data that doesn't work...especially when they don't know why it soesn't work.  My sverage download speed is between 1 and 2.5Mbps and on a few rare occations have seen it go up to 5Mbps

    I added a potential fix to another thread recently. So far people seem to be having success with it, I'd love to see more people test it out:
