There is only one signaling channel for the supplementary services.
Only one supplementary service operation can be active at a time. (Or
two, network can initiate ussd notify or request while
mobile-originated ussd is pending.)
Thank you for the info. When you say only one MO ss operation can be active at a time, do

hardware specific?
