Description:
BACKGROUND OF THE DISCLOSURE 
     1. Field of the Disclosure 
     The invention relates to a Subscriber Identity Module card for use with wireless devices. More particularly, the invention relates to a variable, multi-sized Subscriber Identity Module card for use with a variety of wireless devices. 
     2. Related Art 
     A large number of wireless service plans and wireless devices exist for customers desiring wireless or mobile services such as data, talk, text messaging, and various applications and games. The wireless service plans may be compatible with a variety of wireless devices which may employ different hardware. One piece of hardware used by wireless devices is a Subscriber Identity Module (SIM) card. SIM cards exist in a variety of sizes, shapes, and widths, and most wireless devices are limited in terms of which size SIM cards may be compatible with those wireless devices. Wireless device users are not always aware of which SIM card size works on the users&#39; wireless devices, and may sometimes purchase an incorrect SIM card for their wireless device. In addition, some wireless service plans may be compatible with a variety of mobile devices which may use SIM cards of different sizes and types. 
     Existing SIM cards may be purchased in kits containing multiple sizes of SIM cards. In these kits with multiple SIM card sizes, a customer may select the SIM card that works with the customer&#39;s wireless device. However, this selection may result in unused SIM cards. Additionally, SIM cards may be purchased in forms where one smaller SIM card can be removed from a larger SIM card, but the smaller SIM card may not be reused with the larger SIM card after it has been removed from the larger SIM card. By developing a mufti-sized SIM card for wireless devices, there may be fewer unused SIM cards, less confusion in selecting a SIM card that works on a user&#39;s wireless device, and more convenient switching of SIM cards for different wireless devices.

     DETAILED DESCRIPTION 
     In this specification and claims it is to be understood that reference to a wireless device is intended to encompass electronic devices such as mobile phones, tablet computers, gaming systems, MP3 players, personal computers, PDAs, and the like. A “wireless device” is intended to encompass any compatible mobile technology computing device that can connect to a wireless communication network, such as mobile phones, machine-to-machine (M2M) equipment, Internet-of-Things (IoT) devices, mobile equipment, mobile stations, user equipment, cellular phones, smartphones, handsets, or the like (e.g., Apple iPhone, Google Android based devices, BlackBerry based devices, other types of PDAs or smartphones), wireless dongles, remote alert devices, or other mobile computing devices that may be supported by a wireless network. The term “wireless device” may be interchangeably used and referred to herein as “wireless handset,” “handset,” “mobile device,” “device,” “mobile phones,” “mobile equipment,” “mobile station,” “user equipment,” “cellular phone,” “smartphones,” “monitoring device” or “phone.” 
     Wireless devices may connect to a “wireless network” or “network” and are intended to encompass any type of wireless network to obtain or provide mobile phone services through the use of a wireless device, such as the Global System for Mobile Communication (GSM) network, Code-Division Multiple Access (CDMA) network, and Long-Term Evolution (LTE) network that may utilize the teachings of the present application. 
     Reference in this specification to “one aspect,” “an aspect,” “other aspects,” “one or more aspects” or the like means that a particular feature, structure, or characteristic described in connection with the aspect is included in at least one aspect of the disclosure. The appearances of, for example, the phrase “in one aspect” in various places in the specification are not necessarily all referring to the same aspect, nor are separate or alternative aspects mutually exclusive of other aspects. Moreover, various features are described which may be exhibited by some aspects and not by others. Similarly, various requirements are described which may be requirements for some aspects but not for other aspects. 
     A large number of wireless service plans exist for customers desiring wireless services such as data, talk, and text messaging. To obtain these wireless services, customers generally have the option of entering into a post-paid service, e.g., contract for a period of time, or a pre-paid, contract-free service. The latter offers customers the freedom to initiate and stop wireless services without incurring expensive cancellation fees associated with a post-paid service. 
     Generally, companies that provide post-paid wireless services are wireless carriers or Mobile Network Operators (MNO) that maintain and control their own wireless networks. An MNO heavily relies on backend systems to address any provisional, billing, security and data issues that might threaten the health of their networks. On the other hand, a Mobile Virtual Network Operator (MVNO) is a mobile operator that typically does not own its own frequency spectrum or have its own network infrastructure. MVNOs negotiate and enter into business agreements with third party wireless carriers or MNOs to purchase the right to use their networks for wireless services including voice and data. MNOs and MVNOs may provide service for a variety of wireless devices compatible with various sizes of SIM cards. 
       FIG. 1  illustrates an exemplary wireless device  10  and its potential components. The wireless device  10  may include a transceiver  12 , a power supply  13 , a display  14 , a computer readable medium  16 , a processor  18 , a SIM card  22 , a client  154 , a memory  116 , an audio input/output device  124 , an operating system  126 , and the like. The transceiver  12  can include, for example, a wireless antenna and associated circuitry capable of data transmission with the mobile data network utilizing at least one data transmission protocol, such as, for example, 3G, 4G Long Term Evolution (LTE), 5G (5th generation mobile networks/wireless systems), Evolution-Data Optimized (EVDO), Code Division Multiple Access (CDMA), High Speed Packet Access (HSPA), Global System for Mobile Communications (GSM), W-CDMA (Wideband Code-Division Multiple Access), Wi-Fi, Bluetooth, a communication channel as defined herein, and/or the like, and/or combinations thereof. The transceiver  12  may transmit and receive data over the data transmission protocol. 
     The SIM card  22  may be implemented as a Universal Integrated Circuit Card (UICC). The official definition for UICC is found in ETSI TR 102 216[2] where it is defined as a “smart card that conforms to the specifications written and maintained by the ETSI Smart Card Platform project.” For brevity, the SIM card  22  will be referenced throughout, but the invention is equally applicable to a UICC. The SIM was initially specified by the European Telecommunications Standards Institute in the specification with the number TS 11.11. This specification describes the physical and logical behavior of the SIM. It is further noted that 3GPP is now responsible for the further development of applications like SIM (TS 51.011) and USIM (TS 31.102) and ETSI for the further development of the physical card UICC. 
     The display  14  of the wireless device  10  can display various information provided to the display  14  from the processor  18  of the wireless device  10 , computer readable medium  16 , or SIM card  22 .

       FIG. 3  illustrates the packaged tri-cut SIM card  230 . The micro-SIM card  224 , the mini-SIM card  226 , and the nano-SIM card  228  may be arranged together in the packaged tri-cut SIM card  230  so that each SIM card  22  may be removed from the tri-cut SIM card  230  or any combination of the SIM cards  22  may be removed from the tri-cut SIM card  230 . 
     To secure the SIM cards  22  in the tri-cut SIM card  230 , the tri-cut SIM card  230  may have one or more connecting mechanisms such as tabs  320  that may connect the micro-SIM card  224  to the tri-cut SIM card  230 , the mini-SIM card  226  to the micro-SIM card  224 , and the nano-SIM card  228  to the mini-SIM card  226 . Each of the SIM cards  22  may be removed from the tri-cut SIM card  230  by snapping the SIM card  22  from the tabs  320  or other connecting mechanisms. In order to facilitate the removal of each SIM card  22  from the tri-cut SIM card  230 , larger SIM cards  22  may have a cut-out space  330  in which smaller SIM cards  22  may be arranged. 
     For example, the mini-SIM card  226  may have a cut-out space  330  in which the micro-SIM card  224  may be arranged. The space may be interrupted by the connecting mechanisms such as tabs  320  or the like to hold the micro-SIM card  224  in place. The micro-SIM card  224  may also have a cut-out space  330  in which the nano-SIM card  228  may be arranged. The spaces  330  may allow for easy removal of each SIM card  22  from the tri-cut SIM card  230  and for easy reconfiguration of each SIM card  22  within the tri-cut SIM card  230 . Alternatively, reconfiguration of each SIM card  22  into a portion of the tri-cut SIM card  230 . 
       FIG. 4  illustrates the removal of the nano-SIM card  228  from the tri-cut SIM card  230 . To remove the nano-SIM card  228  from the tri-cut SIM card  230 , the nano-SIM card  228  may be punched out from the tabs  320  holding the nano-SIM card  228  into the micro-SIM card  224  within the tri-cut SIM card  230 . As will be shown more clearly in other figures within this disclosure, the nano-SIM card  228  may have a different material backing than the micro-SIM card  224  and the mini-SIM card  226  have or may need to have the backing removed in order to achieve the desired thickness of 0.67 mm. 
       FIG. 5  illustrates the removal of the micro-SIM card  224  from the tri-cut SIM card  230 . To remove the micro-SIM card  224  from the tri-cut SIM card  230 , the micro-SIM card  224  may be punched out from the tabs  320  holding the micro-SIM card  224  into the mini-SIM card  226  within the tri-cut SIM card  230 . The micro-SIM card  224  may be removed from the tri-cut SIM card  230  with the nano-SIM card  228  still connected within the micro-SIM card  224  within the cut-out space  330 . The nano-SIM card  228  may be further removed from the cut-out space  330  of the micro-SIM card  224  in a similar fashion as shown and may need to have the backing removed in order to achieve the desired thickness of 0.67 mm. 
       FIG. 6  illustrates the removal of the mini-SIM card  226  from the tri-cut SIM card  230 . To remove the mini-SIM card  226  from the tri-cut SIM card  230 , the mini-SIM card  226  may be punched out from the tabs  320  holding the mini-SIM card  226  into the tri-cut SIM card  230 . The mini-SIM card  226  may be removed from the tri-cut SIM card  230  with the micro SIM card  224  still connected within the mini-SIM card  226  within the cut-out space  330 , and with the nano-SIM card  228  still connected within the micro-SIM card  224  within the cut-out space  330 . The micro-SIM card  224  may be further removed from the mini-SIM card  224 , and the nano-SIM card  228  may be further removed from the cut-out space  330  of the micro-SIM card  224  in a similar fashion as shown. 
       FIG. 7  illustrates the bottom surface of the tri-cut SIM card  230 . The nano-SIM card  228  may be thinner than the micro-SIM card  224  and the mini-SIM card  226  as illustrated in  FIG. 7 . To accommodate for the difference in thickness of the nano-SIM card  228 , the tri-cut SIM card  230  may employ a material layer  750  on the bottom surface of the nano-SIM card  228 . The material layer  750  on the bottom surface of the nano-SIM card  228  may be removable from the nano-SIM card  228 , as shown in more detail in  FIG. 9 . When the nano-SIM card  228  is removed from the tri-cut SIM card  230 , the material layer  750  may also be removed with the nano-SIM card  228 , as the material layer  750  may remain on the bottom surface of the nano-SIM card  228  until it is separately removed from the nano-SIM card  228 . In this regard, the material backing  750  may utilize a less robust material and a less robust adhesive to attach the material backing  750  on the nano-SIM card  228 . 
     In one aspect of the disclosure, the nano-SIM card  228  may be reused within the micro-SIM card  228  after the nano-SIM card  228  has been removed from the micro-SIM card  228 . To reuse the nano-SIM card  228  within the micro-SIM card  224  after the nano-SIM card  228  has been removed from the micro-SIM card  224 , the material backing  750  may be reapplied to the nano-SIM card  228 . This approach may be similarly applied to reusing the nano-SIM card  228  with the other size SIM cards. 
     Alternatively or additionally, the tabs  320  may be configured to mechanically capture and hold the nano-SIM card  228  within the micro-SIM card  224  even after the nano-SIM card  228  has been removed from the micro-SIM card  224  and from the material backing  750 . This approach may be similarly applied to reusing the nano-SIM card  228  with the other size SIM cards. In yet a further aspect, a new material backing  750  may be applied to the nano-SIM card  228  and the micro-SIM card  224  so that it adhesively holds these two cards together. This approach may be similarly applied to reusing the nano-SIM card  228  with the other size SIM cards. 
     The micro-SIM card  224  and the mini-SIM card  226  may instead have a material backing  716 . The material backing  716  may be affixed to a bottom surface of the micro-SIM card  224  and of the mini-SIM card  226  so that when the micro-SIM card  224  and the mini-SIM card  226  are removed from the tri-cut SIM card  230 , the material backing  716  may remain on the micro-SIM card  224  and the mini-SIM card  226 . In this regard, the material backing  716  may utilize a more robust material and a more robust adhesive to attach the material backing  716  on the micro-SIM card  224  and the mini-SIM card  226 . 
     As illustrated in  FIG. 8 , because the thickness of the nano-SIM card  228  may be less than the thickness of the micro-SIM card  224  and the mini-SIM card  226 , the nano-SIM card  228  may have the material layer  750  on the bottom surface of nano-SIM card  228 . This may allow nano-SIM card  228  with the material layer  750  to be removed from the tri-cut SIM card  230  and tabs  320 , but also the nano-SIM card  228  may be removable from the material layer  750  (as shown in  FIG. 9 ). Meanwhile the material backing  716  may remain affixed to the micro-SIM card  224  and/or the mini-SIM card  226 . Both the material backing  716  and the material layer  750  may be adhesives such as glue and the like or a combination of adhesives and materials such as glue and plastic, paper, or the like. The material backing  716  and the material layer  750  may also provide support for each SIM card  22  so that the SIM cards  22  do not break when being removed from the tri-cut SIM card  230 . 
     For example, the nano-SIM card  228  may be 0.09 mm thinner than the micro-SIM card  224  and the mini-SIM card  226 . In this example, the thickness of material layer  750  may therefore be 0.09 mm more than the thickness of material backing  716  in order to make the combined thickness of the nano-SIM card  228  with the material layer  750  the same as the combined thickness of the micro-SIM card  224  or the mini-SIM card  226  and the material backing  716 . By making the combined thicknesses of each SIM card  22  equal while in the tri-cut SIM card  230 , the SIM cards  22  may be flush within the tri-cut SIM card  230  so that they can be properly inserted into, read by, and removed from the wireless device  10 . If the nano-SIM card  228  were not flush, meaning that if the nano-SIM card  228  was positioned within a cavity of the micro-SIM card  224  and/or the mini-SIM card  226 , the SIM card  22  may not read properly within the wireless device  10  or may be difficult to insert into and remove from the wireless device  10 . 
       FIG. 9  illustrates the removed nano-SIM card  228  being peeled from the material layer  750 . The removal of the material layer  750  from the nano-SIM card  228  may allow the nano-SIM card  228  to be used individually. The material layer  750  may be removable from the nano-SIM card  228  in order to allow the nano-SIM card  228  to be used at its normal thickness without the material layer  750 . The material layer  750  may be re-attachable to the nano-SIM card  228  in order to allow the nano-SIM card  228  to be used in combination with another SIM card  22 , the material layer  750  again making up for the difference in thickness between the nano-SIM card  228  and the micro-SIM card  224  and the mini-SIM card  226 .
