What is the difference between USSD and SMS Based calling?

USSD is the standard method used to initiate calls on the RoamForce network. It is reliable, cost effective and set as the default for all calls made from your phone. In a few countries, USSD is not able to be used and the SMS method must be used to initiate calls.
