Both cannot be used at the same time. You have to switch the handset off and back on again to use the other SIM and repeat the procedure to switch back again. Regards.

Hi, I am interested in getting one of those dual SIM card holders for my N82. Before I go ahead an get one, can anyone tell me how it works? I am hoping to use two sim cards at the same time, would this be possible? -------------------- Thank you. Ali
