USSD is a service that allows mobile phone users to interact with a remote application
from their device in real-time. It is a highly scalable service as it does not require an internet connection and is supported by both feature phones and smartphones.
A shared USSD code will be raised on Airtel(It's immediate).
A dedicated USSD code will be raised on TNM and Airtel once you have received the USSD allocation letter from MACRA.
Attached is the rate card for both options.
