USSD (EG: *123#)

Reach and interact with your customers using a low cost, two-way exchange of data known as Unstructured Supplementary Data (USSD)

These interactions are created in real-time on a customer’s mobile phone, independent of the mobile device type, with no download requirement.

Advantages include customer engagement and self-service opportunities like airtime top-up. Grayline Mobile USSD services enable our clients to reach and interact with their customers via a low cost, low touch, and high reach service channel. USSD breaks down geographical constraints and can reach everyone, everywhere, no matter how remotely they are located.

Unstructured Supplementary Service Data (USSD) is a GSM standard that allows high-speed interactive communication between subscribers and applications across a GSM network. It does this by:

* Creating a real-time connection during a USSD session (unlike SMS which is a store and forward protocol).

* Allowing information exchange through a dialogue (two-way exchange of a sequence of data) Supporting messages up to 182 alphanumeric characters in length (longer than a 160 character SMS).
