I recently switched to T-mobile 4g. The data speeds are brutally slow everywhere I go. It's time that T-mobile did the right thing and declared that they don't really offer 4g. Otherwise, customers like me end up feeling scammed. Details: I live near Los Angeles. The coverage map shows 4g in all the spots I want to use it. I need faster data so I invested in the Sonic hotspot and paid for a plan. Same slow data speeds. Very disappointing. Spent time with customer service twice, nice Indian folks. One of the last suggestions was to reset my device. Which would require me to commit many hours reloading everything. That is a horrible thing to do to people that don't know any better.
It's OK T-mobile, to do the right thing and tell people that T-mobile doesn't provide reasonable data speeds. Do the right thing.
