Dingtone và TextNow

Phí kết nối

Dingtone: Chưa công bố. TextNow: Không có. Phí kết nối là một khoản cố định được cộng vào mỗi cuộc gọi bất kể thời lượng, nên chiếm tỷ lệ lớn nhất trong những cuộc gọi ngắn vốn trông có vẻ rẻ nhất khi chỉ so sánh theo phút. Mười cuộc gọi một phút với phí năm xu sẽ tốn thêm năm mươi xu so với mức giá được quảng bá; một cuộc gọi mười phút chỉ tốn thêm năm xu.

Nền tảng

Dingtone hoạt động trên iOS, Android. TextNow hoạt động trên iOS, Android, Web. Điều này quyết định nhiều phép so sánh hơn mức đáng lẽ: một dịch vụ dù tốt đến đâu nhưng không có trên thiết bị bạn đang cầm thì hoàn toàn không phải lựa chọn, còn ứng dụng máy tính quan trọng hơn bạn nghĩ khi phương án thay thế là áp điện thoại vào tai suốt một giờ.
