A dual sim phone is a mobile phone that has basically two sim cards. It has the provision to hold two Sims (two Subscriber Identity Modules). There is absolutely no need for you to carry two mobiles. The latest technology has been able to provide with this facility of carrying a single phone set with two sim cards. You could thus have two Sims one for personal usage and the other for official purposes on a single mobile device. You can just switch between the two sim cards by just operating the phone menu rather than switching it off and on.

Dual Sim phones are beneficial to the working class community. These people have to maintain innumerable contacts both personal as well as professional therefore these phones are indeed a boon to them.

Another main advantage of dual Sim phone is that if you find the coverage of one sim being poor you always have the next sim on hand to switch over easily and make your calls without any hassle. This type of dual sim phones also come at an affordable price. And if you go for a wholesale store or buy bulk number of mobile dual phones, cost wise it would work out much cheaper.

This kind of dual sim phone is being highly appreciated by the business class people. They make full use of the facilities provided by the dual sim mobile phone. One particular sim card is from the origin country, which they belong to and the other one for the place where the business man has gone for his business purpose. So he is able to make his business trip successful without having two sets of mobile phones with him causing unnecessary discomfort.

Earlier there was a facility to insert two sim cards into a single phone but only one of the sim cards could be activated at a time. They had to switch off the phone and switch on again to use the next sim card. Later software was developed to solve this problem which helped users to switch between the cards without switching the phone off and on. But this had its own flaw. Only one line could be used at a time. You could receive calls one at a time.

Earlier, this was not so and users had to switch off and then switch on the set to activate different sim cards. The new technology has cut down the old system to only changing the sim card through menu operation.

Our technology has further advanced to provide us with models capable of enabling continuous usage of dual cards. A combination of CDMA and GSM technologies are used to transmit voice data. These types of phones are readily available in the market. All information regarding the service providers providing this facility is available on the net.
