KeepCalling과 Rebtel 비교

과금 단위

KeepCalling은(는) 올림 적용 방식으로 청구하고, Rebtel은(는) 분당 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.

크레딧 만료

KeepCalling: 없음. Rebtel: 공개되지 않음. 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.

플랫폼

KeepCalling은(는) iOS, Android, Web에서 작동하고, Rebtel은(는) iOS, Android에서 작동해요. 이 점은 생각보다 많은 비교 결과를 좌우해요. 아무리 훌륭해도 지금 손에 든 기기에서 사용할 수 없는 서비스는 후보가 될 수 없어요. 한 시간 동안 휴대전화를 귀에 대고 있어야 하는 상황이라면 데스크톱 클라이언트의 중요성도 생각보다 커요.
