PrefixCall is a personalization app developed by 84DOM for Android users. It is a handy solution for those who need to add prefixes to their calls, especially for business purposes. Due to a new privacy restriction policy by Google, automatic interception of outgoing calls is no longer possible. Therefore, PrefixCall allows users to select the desired prefix (such as 4146, #31#, 4088, and 456) within the app before making a call.

The app offers several features, including automatic addition of prefixes when making calls, the ability to store the selected prefix, and the option to deactivate the service when not needed. This app is particularly useful for those who use business SIM cards that require the addition of a specific prefix. With PrefixCall, users no longer have to modify their contacts' numbers or face issues with other apps that rely on phone number recognition.
