Can you make sure the delivery of each text message that I send? No. We called API to send message to the carrier. However, whether the message can be delivered depends on the network conditions and we do not have control on that.
If the message does not go through, am I charged? Yes.
How the credits cost for each message calculated? It depends on the encoding method. By default SMS tried to use GSM-7 encoding. However, if the message contains charsets (like Chinese words) that cannot be encoded using GSM-7, it is going to fallback to UCS2. If the SMS message can be encoded using GSM-7, the maximal size for a single SMS text is 160. SMS longer than that is break into 153 char segment. Say a message is able to be encoded using GSM-7 and the length is 161. The SMS will have 2 segments (153 char segment + 8 char segment). If a SMS message is encoded using UCS2, the maximal size for a single SMS text is 70. SMS longer than that is break into 67 char segments. 1 credit represents 1 segment in SMS text message.
Can I see response to my message? No. All message are outbounds only. We will add ” -No reply” at end of each message. We recommend to add source information like “From Sutter Health:” into the text message.
