Skype와 Viber Out 비교

서비스 상태

Skype: 철회됨. Viber Out: 운영 중. 소비자 대상 서비스가 중단됐다면 장점이 무엇이었든 후보가 될 수 없어요. 계정 판매가 중단되고, 사용하지 않은 크레딧은 전환되거나 소멸되며, 지원도 끝나요. 사용하던 서비스가 종료되어 이 페이지를 찾았다면, 아직 운영 중인 서비스끼리 비교하는 것이 의미 있어요.

과금 단위

Skype은(는) 분당 방식으로 청구하고, Viber Out은(는) 올림 적용 방식으로 청구해요. 분당 요금이 같아도 최종 청구액은 달라지며, 대부분의 사람이 통화하는 구간에서 그 차이가 가장 커요. 35초 통화를 1분으로 올림하면 해당 통화에 약 70퍼센트의 추가 요금이 붙지만, 요금 자체가 바뀐 것은 아니기 때문에 어떤 요금 비교표에도 나타나지 않아요.

연결 수수료

Skype: 과금됨. Viber Out: 없음. 연결 요금은 통화 시간과 관계없이 모든 통화에 추가되는 고정 금액이에요. 그래서 분당 비교에서 가장 저렴해 보이는 짧은 통화에 비례상 가장 크게 적용돼요. 연결 요금이 5센트인 1분 통화 10번은 표시된 요금만 봤을 때보다 50센트가 더 들지만, 10분 통화 1번은 5센트만 더 들어요.

크레딧 만료

Skype: 만료됨. Viber Out: 없음. 만료되는 크레딧은 어떤 요금표에도 나타나지 않는 비용이며, 한 번에 얼마나 충전하는지와 얼마나 불규칙하게 통화하는지에 비례해 중요해져요. 비상시에 쓰려고 구매해 두고 사용하지 않은 잔액이 바로 비활성 규정으로 차감되는 잔액이에요.
