As Des mentioned in your other support thread, you need to contact our sales department.

Your license is for the NowSMS Modem Edition. That product edition only supports modems for outbound SMS sending. (It can function as an SMPP server and accept SMPP clients, but it cannot use SMPP for upstream/outbound SMSC connections.)

Please see:


NowSMS is available in four different editions designed to meet different customer requirements.

NowSMS MMSC Edition: This edition is designed for use as an operator MMSC, and supports full SMS and MMS functionality, including support for automatic provisioning of MMS subscribers.

NowSMS Gateway Edition: This edition is designed for service providers, corporate customers, developers and testing services. All types of SMS and MMS connectivity are supported. MMS functionality excludes support for automatic provisioning of MMS subscribers as required in a mobile operator environment.

NowSMS Modem Edition: This edition is designed for sending and receiving SMS and MMS messages via multiple GSM modems or Android phones only. All developer APIs, including SMPP, HTTP, SMTP, and MM7 are supported for client connections only.

NowSMS Lite (Single Modem Edition): This edition is designed for simplified installation and setup. This edition supports sending and receiving SMS and MMS messages via a single GSM modem or Android phone only. NowSMS Lite can be updated to other editions by purchasing a license upgrade.

The trial version of the Now SMS/MMS Gateway provides the full functionality of all product editions.
