hi guys..
would like to know some info..

now i'm using a plan (dunno what it name) where my gf is as a main with RM50 monthly and mine is RM30 monthly.. where we got free call & free sms etc.. between us.. Friends & Family plan i guess..

i would like to get a smart plan for me to use the internet..
my question is..
1) i heard that only "main" can change to smart plan.. "sub" can't.. is this true?"
2) let say if i change to main.. and want to get smart plan.. will i still in Friends & Family package where i can make a free call & free sms with my gf if she become my sub..
3) for the smart plan.. RM63 per month including data + call/sms? or the RM63 is totally for data only?

thanks..
