[Q] won't connect to H+ topic

So I'm standing here using smartbro network in Philippines
My wife's galaxy grand prime G530H will connect to h+ on 900, 1800, 1900.

My note 4 910c will not and never did on any modem. Only will connect to H. The note 4 910c is capable of gsm900 And the other bands?

I am running bob4 modem. help?

Screenshots are from the galaxy grand prime. The same service mode on the note 4 just says band 1.

How do I get the note 4 to actually connect like it should?
