    Does it persist after a reboot? How about a cache partition wipe? http://support.t-mobile.com/docs/DOC-5744

    Go to settings - WiFi and check if you have something called Smart network switch. If so, make sure it's off. Some people reported similar problems with this feature.

    Also check for similar options in your carrier settings.

    The Cache Partition wipe that B. Diddy referred to above will not cause the loss of any of your personal data.

    Some Samsung phones have a feature called connection optimizer / manager. Check if you have something similar in settings - more networks - mobile networks. If so, switch it off.

    Also, you can check if there's a conflict with an app that you downloaded. Boot your phone into safe mode and see if the problem persists.
