i hav few question

1. me and my bf register 1+5 plan...my bf as main line and me as a sub-line...if im using this number only to call n sms wif my bf, then i only hav to pay rm5 per month for access fee rite??

2. on a first registration, i need to pay rm25...in a first month, there is a stamp duty charge+access fee...so, it can be deduct from my rm25 or not???
