A dual SIM mobile phone is one which holds two SIM cards. Initially, dual-SIM adapters were made available to use in regular mobile phones to allow them to contain two SIMs, and to switch from one to the other as required. This combination is called a standby dual-SIM phone. More recently, some phones have been produced that can natively work with two SIMs, both of which may be active at the same time. These are active dual-SIM phones. There are also some Chinese triple-SIM phones.
Dual-SIM operation allows the use of two services without the need to carry two phones at the same time. For example, the same handset can be used for business and private use with separate numbers and bills; or for travel, with an additional SIM for the country visited.
Standby dual-SIM phones
Several types of adapters are available. All of them allow only one SIM to be active, and to receive calls, at any given time; they provide various ways of switching from one SIM to the other. Earlier versions required the phone to be switched off and on again to change from one to another. Later models allow the user to switch SIM cards via a menu or by keying in a numeric code, without switching the phone off.
Some adapters require the two SIM cards to be cut to size, fitted onto a special holder and are inserted into the phone's SIM socket; this can be quite risky, since the user might end up damaging the SIM card in the process. Other adapters don't require cutting or modifying the SIM card. The adapter has two slots for the SIM cards, and a small ribbon cable, which is hooked to a PCB that mimics another SIM card. Because of the added circuitry, adapters for some phones, such as those used for older models, like the Nokia 3210 and Nokia 3310, often include thicker battery covers. Recent variations of this setup do away with the added bulk and has more miniaturized components, allowing owners of newer handsets to go to a dual SIM setup.
Chinese Dual Sim Phones
There are many dual sim phones now available from the Chinese market. Examples are the Sciphone i68, i9 and i9 3G. Also available are the KA08 or A1 phones which are some of the smallest dual sim phones ever manufactured. The phones, which also usually include touch screen interfaces and other modern features, typically retail for a much lower price than branded models. Due to the extra battery usage of the additional sim slot the phones are usually supplied with two battery packs. Popular in Asia, these inexpensive dual sim mobile phones are now also becoming available to buy directly from Europe, with reports that both slots are compatible with the majority of the major UK mobile networks.
