Sending Messages

For sending messages, submit_sm and data_sm can be used.

When the characters of a message exceed 160 in a single submission, 9bits will split the messages, billing them accordingly.

Source address

TON (Type of Number) and NPI (Numbering Plan Indicator) are used to specify and interpret the type and format of phone numbers and addresses. TON specifies whether the source address is a phone number or an alphanumeric string. NPI indicates the numbering scheme or plan for the phone number.

TON	Value	NPI	Value
0x00	Unknown	0x00	Unknown
0x01	International	0x01	MSISDN
0x02	National
0x05	Alphanumeric

The type of source address is defined by the source address TON and NPI parameters.

• Alphanumeric sender is limited to a maximum length of 11 characters.

• MSISDN sender maximum length is 13

• If the source address is alphanumeric, we recommend using TON = 0x05 and NPI = 0x00

Destination Address

A 9bits destination address should always be sent as the CC + NDC + SN. This is also referred to as the “MSISDN” of a subscriber. For further information on the MSISDN format, see the ITU-T specification E.164.

TON	Value	NPI	Value
0x01	International	0x01	MSISDN

The type of destination address is defined by the destination address TON and NPI parameters.

• Destination address is limited to a maximum length of 13 characters.

• If the source address is international, we recommend using TON = 0x01 and NPI = 0x01
