FAQ:

Q: What phones have dual SIMs?

A: Dual SIM phones are common in developing countries, especially in Southeast Asia and the Indian subcontinent , with local firms like Karbonn Mobiles, LYF, Micromax and Cherry Mobile releasing feature phones and smartphones incorporating multiple SIM slots.

Q: What phones have two SIM cards?

A: A dual Subscriber Identity Module (SIM) Global System for Mobile communications (GSM) phone is a wireless phone that allows its owner to simultaneously use two SIM cards. This type of phone allows users to associate two separate numbers with a single device. Dual SIM GSM phones can be considered standby dual SIM phones or active dual SIM phones.

Q: What is a double SIM phone?

A: When people talk about a double subscriber identity module (SIM) card phone, they are usually referring to a mobile device that can hold and use two different SIM cards at once. A phone of this type allows consumers to receive calls intended for two separate numbers. The classifications of double SIM card phones are standby and active.

Q: What is a SIM card and why do you need one?

A: A SIM card is necessary for activation because it allows the cellular network to know which phones are using it. Therefore, iPhones (and every other cell phone, too, by the way) need SIM cards to communicate with the cell carrier, which allows them to activate.
