I am using a Hyper-card which supports dual SIM, I use one of them for voice and the other for data (EDGE).

When I switch between two SIMs, the EDGE setting will be reset to default,
APN = wap.cingular
Password = CINGULAR1

Is there any method to change the default values above so that when I switch my SIM there will be no need to input the EDGE setting again. I don't need two settings for my dual SIM, I just use one of them for EDGE.
