I am not sure....I don't see why they wouldn't....sure that it would still improve the reception...I don't use a smart phone...don't want to pay the additional cost of a data plan since I am unemployed....but the way that I see it, is that it should still work the same regardless.
as far as I know, they should....don't see why not....should improve reception on any phone...the directions are on the back of each package on how to install them....goes under the battery.
