Basically, handsets that have two Subscriber Information (SIM) cards are known as dual SIM phones. At first, there were dual SIM adapters that were made available which allowed people to use one of two SIM cards that were in their cell phone. However, recently manufacturers have been making cell phones that permit both numbers to be active simultaneously. These are called active dual SIM phones.
On the same cell phone, you can maintain both a personal number and a work number with this dual SIM function as opposed to carrying around two handsets. In addition, people who travel regularly between two countries can keep a second SIM for their destination country and save on the expensive roaming charges.
Salesmen dream about the dual SIM phone. The salesman can save a considerable amount of money by not having to pay roaming charges because he is using two different service providers. Also, the dual SIM phone is available to the common man because of its reduced cost, and the salesman is very happy with the ability to use two service providers at the same time.
