FAQs

Why isn't carrier acknowledgement successful 100% in all countries?

There are several reasons a carrier may not acknowledge receipt of a message. Some examples are:

  1. Not all carriers support the acknowledgement protocols.
  2. The receiving carrier is not capable of receiving messages, such as a land-line carrier.
  3. The message was blocked by a carrier for going against carrier guidelines.
  4. The destination phone number does not exist.

What happens to messages that are not acknowledged by carriers?

The lack of an acknowledgement does not imply that the message was not delivered to the subscriber, it just means that the carrier hasn't given us any acknowledgement.

Does a successful carrier acknowledgement mean my message was delivered to the handset?

Carrier acknowledgements indicate delivery to the carrier, but does not mean that the destination handset actually received the message. Handset delivery receipts indicate delivery to the destination handset, but it's important to note that not all carriers support these. Where handset delivery receipts are supported by carriers, we include this data in the percentage of carrier acknowledgement.
