Benefits of sub

Hello i am very new to the mudfish , currently i am using ppt and use 2.99 usd pack but its using up data too fast ( 2-3 gigs in 1 day) so i want to change to sub mode but i don’t know how much sub costs and what will happen to my remaining data ( 24 gigs ). Please help, i am very interested in mudfish services.
