Existing have only two kinds of ways usually in order to reduce wandering fee: one is to use the single deck tape-recorder mobile phone to change different SIM card in different places, and still, this kind method is smaller owing to SIM card, and changes calorie requirement dismounting battery etc., carries and use very inconvenience; Two be to use 2 or a plurality of mobile phone, and this way has not only increased the cost of buying mobile phone, and carry a plurality of mobile phones and the accessory trip is cumbersome, therefore, equally very inconvenient.
The utility model content
The utility model provides a kind of many card mobile phones in order to solve the very inconvenient technical problem of the existing mobile phone roaming of prior art.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is a kind of many card mobile phones of design, and described many card mobile phones are provided with at least two SIM card slots that are used to lay SIM card.
Described many card mobile phones also comprise a MCU and the plurality of SIM cards converting analogue switch that is used to switch SIM card that is connected with described MCU, and the output of described plurality of SIM cards converting analogue switch and described SIM card slot electrically connect.
Described many card mobile phones are provided with at least three SIM card slots that are used to lay SIM card.
The utility model is by being provided with plural SIM card slot on mobile phone, thereby different local SIM card can be placed in many card mobile phones of the present utility model, use different cards in different places, thereby can be when going on business to a certain ground, use this locality card on this ground, do not change card and do not need to carry a plurality of mobile phones or dismantle battery, not only cost is lower, and very easy to use.
Description of drawings
Below in conjunction with embodiment and accompanying drawing the utility model is elaborated, wherein:
Fig. 1 is the SIM card slot distribution schematic diagram that the utility model blocks mobile phone more;
Fig. 2 is the fundamental diagram that the utility model blocks mobile phone more.
Embodiment
See also Fig. 1.The utility model blocks mobile phone 1 more and is provided with four SIM card slots 11, and the SIM card slot is mainly used in lays SIM card.Thereby can use 4 different local SIM card to converse and message transmission on a mobile phone, cost of the phone call is to calculate according to the expense of locality, has reduced the wandering fee of great number, also reduces the expense of buying a plurality of new cell-phones, is business people's first-selected mobile phone.Certainly, the utility model blocks mobile phone more also can be provided with two or three, and the utility model does not limit the number of SIM card slot, as long as be provided with at least two, preferably is provided with three or four.
See also Fig. 2.The utility model blocks mobile phone more and comprises antenna, radio-frequency (RF) switch, radio frequency power amplification module, radio-frequency (RF) receiving and transmission module, MCU and the memory that connects successively, and also be connected with between radio-frequency (RF) switch and the radio-frequency (RF) receiving and transmission module and give birth to the table filter, the output of MCU is connected with plurality of SIM cards converting analogue switch, the output of described plurality of SIM cards converting analogue switch and the electric connection of described SIM card slot that is used to switch SIM card.Plurality of SIM cards converting analogue switch is mainly used in the work of switching SIM card 1, SIM card 2, SIM card 3 and SIM card 4, so that when SIM card 1 location, use SIM card 1, when SIM card 2 locations, use SIM card 2, when SIM card 3 locations, use SIM card 3, when SIM card 4 locations, use SIM card 4.
The utility model is by being provided with plural SIM card slot on mobile phone, thereby different local SIM card can be placed in many card mobile phones of the present utility model, use different cards in different places, thereby can be when going on business to a certain ground, use this locality card on this ground, do not change card and do not need to carry a plurality of mobile phones or dismantle battery, not only cost is lower, and very easy to use.
