A:Answer be very careful.....I bought a Samsung Unlocked phone, model 930U, and it will not work on AT&T for call forwarding and wifi calling.
I have been told by AT&T and Samsung, that I needed a model 930A for these feature to work......Have spent uncountable hours trying to make this work, to no avail.
DO NOT COUNT ON A "u" PHONE TO HAVE FEATURES ON A SPECIFIC NETWORK.
