following questions? it's a Samsung phone which is launched in some Asian countries and which can support two connections on a single handset. So basically it has two slots in the back for two SIM cards of different mobile numbers. Kindly refer to the following questions. I needed legitimate answers to the questions listed here-
Thanks

1) Can both connections be used at the same time?

2) Would this dual capability require a larger volume than a conventional set?

3) What happens if one is talking on the one band and a call comes in on the other?

4) Will the system offer features such as e-mail and text messaging?

5) When you say that one can just switch from one system to the other, can that be done within the same call or would one have to terminate the current call and then call on the other band?
