Detailed Information#

Throughput#

Throughput indicates the maximum number of messages that can be sent per second.

SMS

The basic package has a guaranteed throughput of 2 SMS/s.

RBM

The basic package has a guaranteed throughput of 3 RCS/s

Info

When increasing guaranteed throughput, RCS message throughput is 1.5× the SMS message throughput.

Character sets and message length#

A character set defines how characters are encoded in SMS. The character set used has a direct impact on the maximum message length. In the Omnichannel service, the following character sets are used:

  • GSM 7-bit

    • Messages encoded with this character set have a maximum length of 160 characters per single message.
    • The disadvantage is that this character set does not include characters with diacritics or emojis.
  • Unicode

    • A more universal character set that includes all characters used in modern communication.
    • The disadvantage is that messages encoded with this character set have a maximum length of 70 characters per single message.

GSM 7-bit Character Set#

Basic Character Set#

0x0D CR æ - = M Ñ m ñ
0x0E Å ß . > N Ü n ü
0x0F å É / ? O § o à
  • LF is a Line Feed control.
  • CR is a Carriage Return control, or filler.
  • ESC is an Escape to extension table (maps to NBSP).
  • SP is a Space character.

Basic Character Set Extension#

When the GSM 7-bit character set is used, characters from this table count as 2 characters toward the message length.

0x00 0x10 0x20 0x30 0x40 0x50 0x60 0x70
0x00 \|
0x01
0x02
0x03
0x04 ^

0x06
0x07
0x08 {
0x09 }
0x0A FF
0x0B SS2
0x0C [
0x0D CR2 ~
0x0E ]
0x0F \
  • FF is a Page Break control. If not recognized, it shall be treated like LF.
  • CR2 is a control character. No language specific character shall be encoded at this position.
  • SS2 is a second Single Shift Escape control reserved for future extensions.

Automatic removal of diacritics and conversion to GSM-7#

For all inputs, the application offers automatic replacement of Slovak characters with diacritics by characters without diacritics. If you use this option, the GSM-7 character set will be used to encode the message, increasing the maximum message length to 160 characters.

Attention

If the message contains characters that have no equivalent in the GSM-7 character set (for example emojis), diacritics will be removed, but the maximum message length will still be 70 characters, because the message will still contain a character that cannot be replaced.

Message splitting#

If the message text exceeds the maximum length for the given character set, the message can be split into multiple messages using special hidden characters. Such a split message will be sent as 3 separate messages, but on the recipient's device it will automatically be joined and displayed as a single message. The maximum combined length of all three messages is 459 characters for the GSM-7 character set or 201 characters for Unicode.
