Never love anything more than this, comparing with Boostmobile, this focuses more on people like me who want to use the phone for only making calls and sending text. Beside, these codes work and I still can't believe it!
Honestly, I didn't expect to get discount by using coupon and I thought that there aren't any until found one in this site. Thanks!
Until recently, there was no direct, reliable, and secure communication channel available between the SIM and a remote server in the outside networks until we have ptel sim card. In addition, different mobile devices may have different ways for a user to invoke the same or similar SIM application. To improve the user experience, telecom operators have requested Web servers on the SIM cards and the ability to access the SIM via a Web browser in the handset. In the future, a SIM card from Ptel.com will be able to store services that belong to different service providers. Currently, there is no direct, independent, and secure channel for a service provider to update or customize a service in the SIM card without passing by the mobile operator. The methods presented in this paper for SIM communication using Internet protocols address these issues. The methods enable the SIM to establish a reliable and secure end-to-end connection with a remote Internet server for secure online transactions. They also enable the user to access his SIM using a Web browser on his mobile device or on his computer. This not only enhances the human interface to the SIM, but also allows the use of standard applications, such as a Web browser, to communicate with the SIM. Figure 1 illustrates secure communication between the network SIM and other entities. The paper is organized as follows: Section 2 introduces some related works. In Section 3, we describe a method to enable the SIM card as a network node with TCP/IP stack and communication between the SIM and the phone using Internet protocols. Section 4 presents the method to access the SIM in the phone using a Web browser on the desktop. Section 5 describes how the SIM can establish a direct, independent, and secure connection to any Web server on the Internet.
Another type of sim card from Ptel is the Websim which is a solution to integrate a Web server on the SIM card that permits any network node in the Internet to access this Web server, based on the phone number of the mobile device that holds the SIM. The approach consists of a Web proxy that intercepts HTTP requests from a Web client and encapsulates them into SMS messages to send to the mobile phone over mobile networks. There is no TCP protocol stack in WebSIM; therefore, there is no end-to-end secure communication between a WebSIM and a Web server on the Internet based on standard security protocols such as SSL or TLS. In addition, the maximum length of SMS messages is 160 bytes, so performance is not acceptable. Mobile payments play an important role in e-commerce because of the popularity of mobile devices and the integration of mobile networks into the Internet. In addition, the mobile device is a personal device that users carry with them all the time. In these mobile devices, the SIM card is the most secure place to store important personal information. With a network SIM card on the mobile device, the user can use the Web browser on the device itself or on the desktop to buy goods or services on the Internet, but the payment can always be done directly between the network SIM and the merchant server. This provides a secure mobile payment method. Users can use the Web browser on the mobile device or on the computer to access the network SIM to customize personal information, such as phone book, SMS messages, or passwords of other services. Mobile network operators can use the HTTPS protocol to update or modify services and information in the SIM of the mobile device. Deploying applications on the network SIM card will be the same as deploying normal Web server applications. The network SIM card can carry a personal identity server for the mobile user and this identity server acts as an identity provider participating in a network identity federation such as Liberty Alliance Federation. This will allow mobile users to protect the privacy and security of their network identity information and enable access to their services over the Internet by authenticating with the network SIM card only one time (single sign-on standard). Now that we know that a technology that turns the SIM card in the mobile device into a network node. The network SIM card, with its own IP address and an IP/TCP/HTTP protocol stack, is a true network node in the Internet. It enables the use of network security protocols for secure communication between the SIM and other servers on the Internet. This opens a new paradigm for applications in SIM cards and mobile devices.
