these are all codes that work on stock touchwiz samsung roms (i have tested and currently use them all the time)
above android 4.3 and probably below too
im in android 4.4.2 r(NAB) ight now but not sure if they work with NAB modem because i been switch to android 4.3 mk2 modem sometimes
i know they work for sure with android 4.3 MK2 and alot with android 4.4.2 NAB on my us cellular note 3

the two on bottom work better in RUIM/SIM mode and all others work in NV_Only mode
