MatePhone is a calling app specifically designed for Android devices that allows users to make calls with domestic call charges at half the normal rate. The app is developed by LogicLinks Inc. and is free to use. However, it can only be used with SIM cards that have the VoiceMate function option of LinksMate.

One of the advantages of using MatePhone is that if you have applied for the “10-minute all-you-can-eat option,” you can pay for the call within a 10-minute period. Moreover, the app also allows you to use your current phone number when making calls through the app.

MatePhone comes with several features such as a contact list that displays contact information of the terminal, the ability to set frequently used contacts as favorites, a notification function that reminds you of the call after a certain amount of time, and a call history feature that allows you to check the call history within the app. However, it is important to note that the app cannot be used for emergency calls or international calls, international roaming, and other specific phone numbers.

Overall, MatePhone is a great app for those who want to make domestic calls at an affordable rate. However, it is important to ensure that your SIM card subscription is compatible with the app before using it.
