The difference between the basic model SM-R855U and derivative model (SM-R855F) is:
H/W is identical to the basic model and software is as follows.
a. RF Supported Band is Different.
(R855U: 3G (B2, B4, B5), 4G (B2, B4, B5, B12, B13, B25, B26, B66, B71))
(R855F: 3G (B1, B2, B4, B5, B8), 4G (B1, B2, B3, B4, B5, B7, B8, B12, B13, B20, B25, B28, B66))
– In EUR R855F : 3G (B1, B5, B8), 4G(B1, B3, B5, B7, B8, B20, B28)
b. All other protocol part is the same.
c. All other features of Volte, SUPL is the same.
d. In USA & Canada, 4G (B7) disabled by MCC code.
Because the device doesn’t support B7 roaming in USA & Canada
