If you call its customer service hotline 1000 or 1833 833, you can actually sign the contract by video recording of mutual conversation on the phone. There is no need to visit any retail stores doing so.
I also sign my contract via home telephone and some extra discounts are offered. Usually the telephone salespersons can offer more benefits than those in retail shops. You can follow my two phone numbers above to check.
Hope I can help you.
