Description

533728 V. Description of the invention (1) [Field of the invention The method of operation of the present invention, telephone SIM card, achieved on the phone [Background of the invention Press, Xi & Switch using telephone 1 a Telephone set 1 a. Card-type prepaid card type. 'And when connected, so as long as the plug-in unit deduction only need to go to the store to remember to carry the IC power' even if you see again, shown) so far 'to carry and handle machine. The operation of the mobile line is a wireless public telephone device that can use the SIM card, and particularly relates to a method that can be used on a wireless public network by using a built-in or built-in add-in card to a wireless public communicator. Know the public telephone system, such as the first through a separate telephone line 2 a) complete the connection 'and each of the public telephone 1 a from the early, users do not need to bring 1C phone card 4a into the plug-in will be Timed and deducted the IC card can be used at any time. The shortcomings of the card-type public telephone 1 a cannot be used after it is removed, and the new IC phone card 4 a, the phone card 4 a, and no vending card can be found. With the development of mobile communications, the public telephone 1 a has become a popular product. It is very convenient to make the product, and the telephone 5 a is used to achieve wireless transmission and communication through internal insertion. 3a with the parent (such as the telephone line 2a of the telecommunications bureau has designated a coin-operated coin type, which has been developed to the current level. A lot of coins can be dialed after purchasing the hole 11a to use the billing unit in the phone card 4a. It is quite convenient. In order to: once the 1C phone card 4a cannot be replenished with stored value, in addition, when the user temporarily forgets to sell the 1C phone card 4a in the store, he can be astonished. Mobile phone 5a (as shown in the second picture, due to its increasing volume) The smaller the better the quality Thus the SIM card 6a almost everyone with hardware electrical energy, will be turned on when the count

Page 4 533728 V. Description of the invention (2) ~ The fee and σ have been recorded on the user's telecommunications bill, so as long as the fee is paid on time, there will be no problem of invalidation of the card. In addition, in order to prevent the mobile phone 5a from being stolen, each SIM card 6a: set a password to lock the SIM + 6a. Only when the user enters the correct makeup code, the mobile phone 5a will enter the normal use state. And after three consecutive mistakes, the SIM card will be locked immediately. The unlock code must be used to crack the password. Therefore, it has the role of security and confidentiality, and the SIM card 6a can also be used to register the important user. Data and information.

However, 'the SIM card 6a is generally limited to mobile phones 5a, and rarely used. It is a pity that it is used on other communication devices, and the SIM card 6a cannot be inserted into the public phone on the market. The purpose of la is to reach the communicator. Therefore, it often happens that when the mobile phone 5 & is out of power, even if a public phone la 'is installed nearby, it can only lament the SIM card 6 & useless. . The entrant 'continued the discussion of the use of existing public phones 丨 a, and there are service providers who provide J p dedicated Internet phones'. At present, in Taiwan, this function can only be handled with credit card providers first. Phone la, just enter the designated speed dial code, 俟 enter the system and then enter the card number and password, 俟 when the user number is correct, you can talk to the recipient. In addition, 'in some countries, you can directly purchase a p phone card from a p network operator'. You do not need to insert a card when you use it, you only need to enter the designated phone network (such as GSM public network, wired phone network, etc.) Speed dial code. After entering the system, enter the card number and password. If the user number is correct, enter the user number to call the recipient.
