Nope, can work. I was from giga then moved to vivifi and reused the old giga account to redeem promo code from this thread.I no longer have lines with giga already, but I did have giga lines before, after which I ported to other providers liao.
Currently my account has no lines. Maybe the promo codes dun let existing accounts get new $0 lines.
Just get new number first during sign up then on ~10 july before 6:30pm activate and port over.Would those booking their Giga SIM card delivery date w Giga check how far ahead can we book a SIM card delivery date in this https://giga.com.sg/feelinggood marketing campaign?
My existing telco billing cycle ends on 14 July.....
