Dual SIM mobile phones are phones which allow you to fit two different SIM (Subscriber Identity Modules) cards in the same phone. With a dual SIM mobile phone you can easily call from either sim card. As both sim cards are in standby at the same time you can receive a call from either at any time. The same applies with messages as you can also send or receive from either sim card without having to switch. the only time that only one sim is active is if you are actually engaged in a call.

Cost savings

Support for two different sim cards allows you to save money by using the sim that represents the best value. An example of this is if you are in a foreign country you can use a local sim card in your dual sim phone for calls to that country. This traditionally gives you far cheaper calls than the roaming sim card.

Only carry one mobile phone

Dual SIM mobile phone owners do not have to carry two mobile phones, they have the benefit of being able to receive calls from business on sim 1 and friends and family on sim 2 at all times.

Cheaper call rates

Phones with dual sim allow you to choose between two different sim cards from different networks and rates. This allows you to use the SIM that represents the best value to make cheaper calls. Good examples of this are vodafone and lebara.

Dual SIM mobiles phones allow business travellers to insert a SIM from a foreign phone network. This means that they can use their dual SIM mobile to make local calls for cheaper rates. Meanwhile, they are still reachable all the time by friends and family on their home SIM.
