This application discloses a display method and an electronic device, and relates to the field of terminal technologies. The method includes: sending, by the electronic device in response to a first operation, a profile download request to an operator network; and receiving a profile, where the profile includes profile metadata, and the profile metadata includes at least one field; and in response to a second operation, displaying a first screen on a display based on the profile metadata, where the first screen includes at least one of a first option indicating a network standard, a second option indicating a card type, a third option indicating account balance information of the profile, a fourth option indicating information about a remaining data volume of an account data plan, and a fifth option indicating a state of an account. This allows a user to learn profile capabilities before activating the profile.

Apparatuses, methods, and systems are provided for securely configuring a Java Card virtual machine operating on a cellular device's application processor. In one embodiment, a connected device with an integrated cellular modem, a virtual universal integrated circuit chip and an integrated fingerprint scanner are used. In another embodiment, the cellular device's built-in camera is used, instead of an integrated fingerprint scanner, to capture the user's facial image.

This disclosure provides methods, systems, services, and platforms for automatically prompting a user of a mobile device to follow an entity on a social media network after a triggering event. This disclosure enables Mobile Network Operators to generate more followers on social media, and, thereby, connect better with potential customers or fans. When a business, group, or other entity has an active social media campaign, a message comprising instructions to launch a browser on a mobile device and navigate to the entity's social media page is sent automatically after a triggering event occurs.

Asynchronous and/or synchronous zero charge telephony protocol systems and methods may include an asynchronous signaling switch and/or a call duration time quota from a synchronous charging onset to place and complete a call. A call request is received with a second device mobile address. The asynchronous systems include instructions to automatically modify the mobile address with a routing prefix when the first device has insufficient balance or independent of balance, route to the asynchronous signaling switch based on an associated modified address trunk path, revert to the call signal at the asynchronous signaling switch, and deliver and automatically disconnect the call immediately when the call is completed. The synchronous systems include instructions to automatically set the call duration time quota upon insufficient balance, and deliver and automatically disconnect the call from the second user mobile device when the call is completed and the call duration time quota is exceeded.

This disclosure provides aspects and embodiments of methods, services, and platforms for prompting users with a zero account balance to send a callback message to a contact informing the contact that the user cannot call them and asking the contact to call the user. This disclosure further provides location determining platforms and rewards platforms for users.

This disclosure provides systems, methods, services, and platforms for prompting a user to respond to an offer on a mobile device. The disclosure enables Mobile Network Operators to create campaigns to target customers who are nearing the limit of their data plans, voice plans, SMS plans, and MMS plans. In some embodiments, the cloud server interacts with a client application to prompt the use of a mobile device to respond to an offer send in a campaign. The disclosure also provides embodiments to check to see if the user has opted out of receiving offers, or if a device can not execute a command, or if a threshold number of offers has already been sent. This disclosure also provides embodiments for authenticating third party account log-in.

This disclosure provides methods, systems, and platforms for automatically prompting a mobile device user to download an application to their mobile device after a triggering event. Triggering events include calling a business, receiving a call from a business, and navigating to a website. In some embodiments, a business can run a targeted campaign to automatically prompt a mobile device user to download an application. In some embodiments, the platform interacts with an application installed on the mobile device. The prompt displayed on the mobile device includes an actionable option to download an application.

This disclosure provides aspects and embodiments of methods, services, and platforms for prompting users with a zero account balance to send a callback message to a contact informing the contact that the user cannot call them and asking the contact to call the user. This disclosure further provides location determining platforms and rewards platforms for users.

Asynchronous and/or synchronous telephony protocol systems and methods may include an asynchronous signaling node (ASN) and/or a call duration time quota from a charging onset to place and complete a call based on a first device call request as received from a first user mobile device on a packet switched network. The asynchronous systems include instructions to automatically modify the telephony address with a prefix and destination address when the first device has insufficient or independent balance or upon a network exception; route the modified call signal to the ASN; and deliver and automatically disconnect the call when the call is completed. The synchronous systems are balance-independent and include instructions to automatically set the call duration time quota upon such exception, and deliver and automatically disconnect the call from the second user telephony device when the call is completed or when the call duration time quota is exceeded.

An apparatus enables communication between a user device and a communication server. The apparatus receives a device identifier of the user device and determines after searching a device-to-token database that the device identifier is not associated with any device communication token. The apparatus activates a predetermined application on the user device, and thereafter receives a device communication token of the predetermined application. A mapping of the device communication token with the device identifier is stored in the device-to-token database after which a communication account is created for the user device on a communication server. A login credential for the communication account is sent to the user device in a message addressed to the predetermined application and transmitted via a message server. The predetermined application on the user device receives the message, and thereafter automatically logs in to the communication server according to the login credential in the message.
