The connection is established via our SMS gateway, which allows sending messages using the SMPP protocol versions 3.4 and 5.0.<\/p>\n\n\n\n
SMPP server address: smpp.unibell.ru<\/code><\/p>\n\n\n\n
Port: 5070<\/code><\/p>\n\n\n\n
Connections in BOUND_TRX<\/code> mode are supported.<\/p>\n\n\n\n
Multiple connections<\/h2>\n\n\n\n
The server allows only one active connection per login to ensure correct delivery of statuses. Therefore, when a new connection is established, any previously established session with the same login is automatically terminated. At the same time, multiple connections with different logins linked to the same personal account and the same balance can operate simultaneously.<\/p>\n\n\n\n
Sending an SMS message<\/h2>\n\n\n\n
To send an SMS message, use the SUBMIT_SM<\/code> command according to the specification.<\/p>\n\n\n\n
The following encodings are supported:<\/p>\n\n\n\n
\n
7-bit GSM for Latin text with support for European characters (data_coding=0<\/code>);<\/li>\n\n\n\n
8-bit ISO-8859-1 (ASCII) for Latin text or binary data (data_coding=1<\/code>);<\/li>\n\n\n\n
UCS2 (UCS-2BE or UTF-16BE) for national alphabets (data_coding=8<\/code>).<\/li>\n<\/ul>\n\n\n\n
For an SMS message, the esm_class<\/code> field in SUBMIT_SM<\/code> must be set to 0.<\/p>\n\n\n\n
The transmission rate must not exceed 100 messages per second. If this limit is exceeded, a THROTTLING<\/code> error will be returned in SUBMIT_SM_RESP<\/code>. For higher sending rates, multiple incoming connections with different logins should be established.<\/p>\n\n\n\n
When automatically returning the status in the DELIVER_SM<\/code> command, standard TLV parameters are transmitted:<\/p>\n\n\n\n
