Hi guys
I am installing a touchwiz based 4.3 rom and it suggesting that i install Chinese mk6 modem, any problem installing with that?

Though i installed few custom roms before but modem part i haven't figured out yet. As per reading on xda this modem seems to have fixes lot of touchwiz 4.3 issues.
I wonder if this modem relevant to us here and do i loose network?
Thanks for this advise.
Btw am on galaxy s3
