I just purchased a Galaxy Tab with 3 g on Bell Mobility.(HSdpa) Initially the 3g worked,as well as the wifi. OF course, I could not leave well enough alone, and now, the 3g does not work. The bars are there, the data pack upload and download symbols are there, but I get a message"Data Connectivity Problem" The server failed to communicate Try again later" I checked to make sure I had the data pack and data pack roaming checked, but what else am I missing? I have already talked to Bell to make sure it was not something from their end, but they say things are as they should be. Any suggestions would be appreciated.
