Message Splitting and Limits

You decide what happens to the incoming texts. Regardless of whether an incoming text message is to be sent directly to a system or forwarded to a specific employee. Or whether keywords should trigger predefined scenarios. The sending status is returned directly to the sending application (upstream application) to provide a convenient overview.

Rely on the fastest delivery possible when situations are urgent. For example, when sending mTANs or time-sensitive access data for two-factor authentication. With Retarus Enterprise SMS, your texts are delivered to the mobile carrier within milliseconds.

Choose from numerous setting options that match your processes. Lower costs using functions such as smart replacement of invalid characters or ensure recipient’s total satisfaction with off-period at night as well as automatic allowlists and blocklists for undesired marketing.

Ability to send/receive longer, interlinked SMS. Texts over 160 characters must be split up and sent as multiple-linked messages. Customers can set a max number of permitted message fragments. Each SMS can consist of up to 153 characters using GSM-7 coding and up to 67 characters using UCS-2 coding.
