A lot of the problems are already starting to arise due to smartphone tech. While advanced users know the issues which have been present on Sprint for over a year now, your average Joe is just starting to experience them and learn that other carriers are not like this when it comes to date.
Every app is getting bigger in size as they become more and more robust. On top of that, many apps have high quality imagery = requires decent speeds. More and more users use social media = decent data required. More and more users use social media picture sharing apps = decent data required. Push news update, videos, etc etc... all of that requires decent data speeds, otherwise you sit there and buffer. With Android web browsing becoming even more robust, and iPhone is being similar... decent data speeds are essentially required to do anything. And while some of the people can be on wifi for majority of the time, many are not always in WIFI area.
So, what is happening now? Users start to ***** about how slow their phone is, which isn't the phone, but the network. Big read and ATT have LTE going live all over. Where are they going to be by 2014 when sprint will just have basic LTE coverage in some cities? Where will smartphone tech be in 2014? Do you guys think many will want to sacrifice their smart phone experience for unlimited data on the buffer now network?
