Not a fail...LEARN before you type a comment. They are not like Verizon phones that require an LTE radio and a seperate CDMA radio to allow simul voice and data. LTE is a data only network still for both carriers, however, AT&T is able to use a single radio for all bands. Although LTE is data only, AT&T devices can go to HSPA+ or older technologies to allow the simul voice and data still. Until VOIP over LTE is done, AT&T actually has the upper hand with device batt life, size, ability to produce faster, slimmer and wont suffer such a heavy drop from LTE to other network technologies. I feel they have a better plan. So, again...FAIL sir is on your comment!
