Hmm. Does anyone else find it a little odd that AT&T has to provision 4G HSPA+ and 4G LTE plans separately? Why is that? You have the amount of data you have. Wouldn't what kind of data you are using depend on your device's capability and whether you're in a given area?
Because AT&T sucks ass! They have the worst customer service I have ever experienced with a company, and their data service is not much better than their customer service. I left them and switched to TMobile. Data speeds range between 2 and 3 times faster (ranging from 9 to 20 mbps). I thought the reception was going to be terrible, but so far (after almost 2 months), I've been amazed. Even driving through no-mans-land in rural AL, as well as TN, I've had constant cell service, and when I lost H+, I still had Edge for data (not fast, but it's there). GPS navigation NEVER failed, which is my only real concern when a trip sends me well outside of any city. I'd say screw your last few months, get happy on a carrier that will make your phone fly.
