Messaging applications that can be used for free are changing the way people communicate with each other. However, the privacy and security controversies that have accompanied this change have never stopped.
Application core functionality
The most attractive feature of this type of application is free calls and text messages. As long as users are connected to Wi-Fi or cellular data, they can start voice and text communication with people anywhere in the world. This completely breaks away from the traditional operator's billing model based on minutes or number of messages.
For those users who have international contact needs, this advantage is particularly obvious. Even if you talk to relatives and friends overseas for several hours, there will never be a shocking phone bill. It can make daily communication across regions as easy as sending an email, and it can also be done at zero cost.
How to obtain and use
In the Apple App Store or Google Play Store within the mobile app store, users can directly search for the application name to download and install it. The entire process usually takes a few minutes and does not require a complicated registration process.
After completing the installation, the application will guide the user to create an account based on email or mobile phone number. After the setting is completed, the user will obtain an exclusive virtual number, and this number is used to make free calls and send and receive text messages.
Query device identification information
For example, let’s look up the ICCID of a mobile phone, which is the unique identification code of the SIM card. On Android devices, users can enter the "Settings" menu, find the "About Phone" option, and then check "Status Information" and "SIM Card Status" to find the ICCID number.
For users of Apple iPhones, the path is slightly different. You need to click "Settings" in order, then click "General", and then click "About This Mac". After pulling down the page, you can see the detailed information of ICCID, and users can copy and use it directly.
Comparison with traditional services
Historically, traditional operators have often used the package model and bundled sales based on call duration, number of text messages, and data traffic. Even users who only use one of the services must pay the fees stipulated in the entire package when they actually pay. The flexibility is quite poor.
In contrast, free messaging apps completely separate call and text messaging functions to achieve zero fees. Users only pay for the mobile data actually used. This usage model based on demand is more user-friendly in terms of cost control.
Potential risks and shortcomings
The biggest limitation of this type of application is that it relies on the network. In an environment where the network signal is poor or there is no Wi-Fi, its core functions cannot be used. At times like these, traditional cellular calls are still a more reliable option.
Another concern is the security of user data. Call content and text message content are transmitted through the application developer's server. Its data encryption policy and privacy protection measures are directly related to whether the user's communication content will be obtained or used by a third party.
Future development trends
With the increasing popularity of 5G networks and the gradual decline in tariffs, the audio and video call quality of this type of application will further develop in the direction of improvement, achieving lower latency, and giving users an experience closer to or even surpassing the effect of traditional telephone calls. It may initially exist as a supplementary role and gradually evolve into one of the mainstream communication methods.
In the future, there is even a high probability that the application will integrate more office and social functions, such as connecting with corporate communication software, or setting up internal translation tools, so that cross-language communication will not be hindered. Its positioning will change from a simple communication tool to a comprehensive connection platform.
