A dual SIM mobile phone is one which has two SIMs (Subscriber Identity Modules). Dual-SIM adapters are available to allow cellphones to contain two SIMs, and to switch from one to the other as required.

In dual sim phone you can use two sim in one phone but only one sim is activate at a time. you can not use one sim at a time. this phone is useful if user is GSM and CDMA user. He can use GSM and CDMA sim in one phone there is no need to carry two phone.
