The Point Of Dual Sim Cards Dual Sim Card Phone.?

Dual Sim Card Phone.? - the point of dual sim cards

I work abroad and I have two phones. One with a SIM card in the United Kingdom, and the other with a Dutch SIM card. Does anyone know of a phone that it will hold two SIM cards. These two cards do not need to be active, but the phone must be a mechanism to have the SIM card () not to retrieve and exchange.

I do not see in any Gimik normal phones are today. Camera performance is good and full text would be nice.
Also, if anyone has any other options that experiance and would be of interest to their own people with mobile dual SIM card.
I have also tried to find good independent studies on the providers of mobile dual SIM card. If someone could be in the right direction, the point would be a good site, very grateful.

Thank you in Yahoo deal.
