Overall compatibililty of Samsung Galaxy S8+ with AT&T is 100%. The compatibility of Samsung Galaxy S8+ with AT&T, or the AT&T network support on Samsung Galaxy S8+ we have explained here is only a technical specification match between Samsung Galaxy S8+ and AT&T network. Even Samsung Galaxy S8+ is listed as compatible here, AT&T network can still disallow (sometimes) Samsung Galaxy S8+ in their network using IMEI ranges. Therefore, this only explains if AT&T allows Samsung Galaxy S8+ in their network, whether Samsung Galaxy S8+ will work properly or not, in which bands Samsung Galaxy S8+ will work on AT&T and the network performance between AT&T and Samsung Galaxy S8+. To check if Samsung Galaxy S8+ is really allowed in AT&T network please contact AT&T support. Do not use this website to decide to buy Samsung Galaxy S8+ to use on AT&T.
