j500g globe lock (unlock but mobile data still edge with other network)

I just have question. My phone is J500G from Globe (Philippines). I successfully unlock the phone using a crack z3x because i want to use a different s. I can use the phone now with a different network but it can't have 3G service in any sim slots. But if I'm using Globe sim it does have 3G in sim slot 1, while sim 2 is only GSM. Tried to change in settings or using *#*#4636#*#* but doesn't work. Is there a way to use 3G with a different network with @Nick Verse cm12 rom? Or is there a way to make it work?
