LTE Channel band

[kidboyadm]

HI, i have a Galaxy S5 SM-906K ( Original Firm), and i am in Brazil, where the band is BD7 (2600), but in hidden menu i saw only two options of band, so how can i add more bands ( Brazilian Band 4G )

You can try the instruction in that link with either *#2263# or *#0011#, no problem. (no need root)

S5 SM-906K

I bought a Galaxy Prime SM-906K but can't get it to connect to AT&T 4G LTE even when following all of your steps. Any suggestions?
