Wait, disabling LTE becomes 4G? That doesn't make sense, unless 3G/HSDPA is considered 4G....You can disable LTE in the data options menu, it’ll revert to 4G.
LTE / 5Ge is far superior to 4G on at&t. I routinely pull download speeds of over 100Mb/s. Ping times are lower. Data loads faster. Not to mention VoLTE calls and HD voice...to each his own I guess...Enjoy 2009 tech, OP.
