Patent Application
20050279655
The subject matter of the present disclosure generally relates to a holder for a cellular phone chip and more particularly relates to a holder for one or more cellular phone chips that have a writeable surface for organizing the chips and that are attachable to or insertable in another carrier for carrying items.
Global System for Mobile Communications (GSM) is a predominant mobile phone standard around the world. GSM enables the same cellular phone to work in a number of countries. A cellular telephone uses a cellular phone chip, such as Subscriber Identity Module (SIM) card, GSM card, or a “smart chip.” Herein, such a cellular phone chip is referred to as a SIM card for clarity. The SIM card enables a customer to access an individual account for a particular wireless network in a specific country. SIM cards have standard dimensions of approximately 25-mm long, 15-mm wide, and less than 1-mm thick. The SIM card is typically provided as part of a larger card that is about the size of a credit card. To use the SIM card with a cellular phone, the SIM card is popped-out of the larger card and is installed into the cellular phone. The SIM card typically has a cutaway corner, which facilitates proper orientation of the SIM card when inserted in the cellular phone. Once the SIM card is inserted into the cellular phone, embedded circuitry on the card is electrically connected to internal circuitry of the cellular phone, allowing the cellular phone to be used with a wireless service on a particular GSM network.
Although some carriers provide GSM service in the United States, the infrastructure of the U.S. is not based on a GSM standard, and competing wire carriers have created other standards, such as CDMA and TDMA. In addition, the GSM standard used in the U.S. and Canada is not always compatible with those GSM services provided elsewhere in the world. For example, most GSM phones sold in the U.S. are only compatible with the nation-wide operating frequency of 1900-MHz or 850-MHz. In contrast, GSM services in other parts of the world may use 900 and/or 1800-MHz frequency standards. Furthermore, the GSM services for various countries in other parts of the world may be incompatible with one another.
Due to the differences in GSM services, a traveler may be unable to use their cellular phone in a specific country unless they have a compatible SIM card for that country. In addition, a traveler using a country-specific SIM card outside of its home country may incur expensive roaming charges even when using their cellular phone in countries having compatible networks. With unlocked cellular phones, however, a traveler may purchase several SIM cards for a number of countries where they may be traveling. The traveler can then swap out the SIM card in their phone when traveling to a specific country. Due to the small size of the SIM cards, travelers can have difficulty storing and carrying their SIM cards, and the SIM cards can be easily misplaced or damaged.
The SIM cards are available on a prepaid basis or on a contractual basis. Some prepaid SIM cards have a security mechanism in place that requires the subscriber to enter in a PIN code every time the GSM cell phone is turned on. When a PIN code has been assigned, it is important for the customer not to forget the PIN code. If customer incorrectly enters the PIN code, for example, then the GSM cell phone may be blocked after a number of attempts. If the phone becomes blocked, the customer may have to enter a PUK code to unblock the phone. If the customer enters the PUK code incorrectly, the SIM card may be blocked indefinitely.
For prepaid cards, a traveler can add more talk time to the SIM card by purchasing a recharge card and entering a PIN number from the recharge card into the phone. Recharge cards can usually be purchased at a number of locations, such as post offices, train stations, airports, convenience stores, magazine kiosks, and cell phone stores. If the traveler runs out of credit for the SIM card, they may have to purchase an entirely new SIM card at a high expense. This is true in a number of Asian countries, for example. Because each SIM card has its own unique phone number, PIN code, and other necessary information, travelers may have difficulty keeping track of the various SIM cards that they use when traveling.
The subject matter of the present disclosure is directed to overcoming, or at least reducing the effects of, one or more of the problems set forth above.
A holder for a cellular phone chip, such as a SIM card, is disclosed. The holder includes a card body having a first side and a second side and includes a sheet having edges attached to the first side of the card body. The card body is substantially rigid, and the sheet is substantially flexible. The sheet forms an open pouch on the card body. The cellular phone chip is insertable into and removable from the open pouch. When inserted, the chip is substantially held within the pouch by an interference fit with the sheet and the first side of the card body. The card body can be approximately the same size as the chip or can be approximately the same size as a credit card. Multiple sheets forming multiple pouches can be attached to the card body for holding several SIM cards.
One side of the card body can have a fastener attached to the second side of the card body for attaching the card body to another item intended to carry the holder and cellular phone chip. The fastener can be an adhesive, a tape, a button, a snap, or VELCRO. The holder can have a writable surface for a user to organize and keep track of their various chips used during travel. The writeable surface can be positioned on the card body or the sheet.
A carrier for items including a credit card and a cellular phone chip is disclosed. The carrier can be an organizer, a brief case, a piece of luggage, a calendar, a planner, a wallet, a computer case, a mobile phone carrier, or other such device. The carrier has a slot for holding the credit card. A holder for the cellular phone chip can be insertable into the slot. The holder includes a card body having a first side and a second side and includes a sheet having edges attached to the first side of the card body and forming an open pouch on the card body. The cellular phone chip is insertable into and removable from the open pouch. Once inserted, the chip is substantially held within the pouch by an interference fit with the sheet and the first side of the card body.
