I work for t mobile and they carrief the z, z1, and z3.... Unfortunately they launch their products half a year behind announcement... And the competition surpasses them in the u.s.... Z launched behind s4, z1 behind g2, and z3 behind note 4/i6
Also the z series in the u.s was marketed very badly and the z3 had a lot of issues in the u.s, so bad that t mobile dropped the phone a couple months after launch...... Sony has no presence in the smartphone market anymore in the u.s..... And t mobile said they don't care to carry the z5...... It sucks because on paper the z5 is prob the best phone..... But my own co workers who work at a very high volume store.... Along with other stores have lost any trust if any was there for the z brand from sony.... They relate xperia to trash at t mobile , and it is unfortunate
