I would appreciate some help. I have a T-Mobile branded samsung galaxy s3 and I live in a city with hspa. For the past month or so my data randomly gets stuck several times a day at 400 kb/s. The only way to get it back to normal is to turn on airplane mode, wait a minute, then turn off airplane mode. Afterwards my data speed goes back to normal. This happens in areas that are 4g and when I have full signal. It is frustrating because it happens so often. I dont think it has anything to do with the local towers being worked on because it also happened when I visited Houston over the Labor Day weekend. Please help!
