Hi. I have a grandfathered unlimited plan in nashville and am using a galaxy S3. recently, all of my speedtesting apps report an average of 3-4mbps, and occasionally will be as low as 0.05mbps. When I got this s3, the rep at the store told me i should get a minimum of around 5mbps. Initially I was getting a full 25-35mbps, but since a few months ago speeds have been exceedingly low. I had the SIM card replaced but that had no effect. Another rep at a different store called someone higher up who was supposedly an "engineer", and I was told that because I use a considerable amount of data, I could be throttled quite heavily.
So is this what I'm running into? Or might this be another issue, like a radio problem with the phone or on verizons end? Because 50kbps is quite painful to use... slower than dialup
