SMS Outreach

SMS outreach is a tool to provide inbound and outbound roamers with a variety of information which can engage silent roamers, prevent fear of bill shock, provide a better roaming experience, improve loyalty, and ultimately increase roaming revenues.

Frequent travellers are among the most valuable subscribers and also the most impacted by SMS outreach services. Typically these customers prefer a network that provides them with helpful and accurate information when travelling abroad.


Setting outreach campaigns has never been simpler. The intuitive GUI allows anyone on your team to set placeholders and parameters with completely customizable variables and input fields (regardless of their technical expertise). The system automatically applies the correct placeholder value, eliminating the need for repetitive setup.

Uses REST API Integration

Increase outbound roaming revenue and negotiate better rates

Information on service rates for SMS, calls, and data can be relayed to roamers. Without this knowledge, many roamers avoid using their devices or they buy a local SIM. Informed subscribers use their devices more, which means more revenue for your network. The more your outbound roamers use their roaming service, the more valuable your network is to prospective roaming partners thereby improving your  negotiating position.

Increase inbound roaming revenue and tertiary revenue

Welcome messages with mobile roaming rates and special offers give inbound roamers the information they need to choose your network. When subscribers are in an unfamiliar environment, they often value relevant advertising of useful services. Encourage spending on promotions and other services outside of network usage by sending SMS ads and promotions.

Strengthen your brand and decrease subscriber churn

Communicating your brand in the context of useful information reinforces the most positive feelings towards your network. Impersonal messages are usually ignored, however when travelling, info on currency exchange rates, weather, taxis, embassies, emergency numbers, and other local info is well received (even appreciated). Look after your subscribers and they are more likely to remain loyal customers.
