Updated rule: foreigners can bundle with foreigners of any nationality, or with Korean KT customers — no restriction.
New activations, device upgrades, and contract renewals must apply by the end of the following month to get the discount.
A representative line is chosen at signup (with consent). Existing KT subscribers can also join just for Family Box data-sharing benefits — even without the discount.
