Introduction to Carrier Hub App

The Carrier Hub app is an Android application that offers features such as Voice over Wi-Fi (VoWi-Fi) on devices operating on the Sprint and T-Mobile networks. This app assists the network engineering team in addressing customer-reported service concerns, as stated in their Play Store app description. The app is available in two versions: Carrier Hub by Sprint and Carrier Hub Magenta by T-Mobile USA. Both versions offer the same features, as the two companies merged on April 1, 2020.

Some smartphones come with the Carrier Hub app pre-installed. However, if your device does not have it pre-installed, you may receive constant notifications prompting you to download the app for a better experience. If you encounter such a notification, simply tap on it and follow the on-screen instructions to download and install the app.

Issues Caused by Carrier Hub App

Although the Carrier Hub app offers useful features, some users have reported various issues associated with its use. We will discuss these problems and provide potential solutions.

  1. Battery Drain: Many users have reported an increase in battery draining after updating or installing the Carrier Hub app. While there is no specific data available on the app’s impact on battery life, it is important to address the issues reported by users.

  2. High Data Consumption: Some users have experienced higher than usual data consumption when using the Carrier Hub app. The app continues to run in the background and consumes more data compared to other applications.

  3. Negative Performance: Numerous users have encountered performance-related issues after installing the Carrier Hub app. Common problems include phone freezing and lagging.

  4. MCM Client Requests: MCM stands for Mobile Content Management. Users who have the Carrier Hub app installed often receive notifications related to MCM processing requests. These notifications typically appear after restarting the phone, as it attempts to connect to cell towers. Once the connection is established, the notifications disappear. However, if you are in an area with unstable connectivity, you may continuously receive these notifications. It is important to note that even during network maintenance, you may still receive connection request notifications, rendering text, call, and data services temporarily unavailable.

  5. App Not Responding: Although not a common issue, the Carrier Hub app may crash or become unresponsive. Several factors can contribute to this problem. Clearing the app’s cache, force stopping the app, or performing a factory reset on your phone may help resolve this issue.

Necessity of the Carrier Hub App

Many users wonder if they need the Carrier Hub app, considering the reported issues. If you are an individual using T-Mobile services and have not experienced any problems with the app, it is advisable to leave it installed on your device. The Carrier Hub app enables essential features like VoWi-Fi, which enhances the overall user experience. It is crucial to clarify that the Carrier Hub app is not a virus, spyware, or any form of malicious software.

Uninstalling the Carrier Hub App

While some devices have the Carrier Hub app pre-installed and do not offer an option to uninstall it, there are methods to remove it from your phone. One approach is to root your device or use the Android Debug Bridge (ADB) to gain privileged access and uninstall the app. We will outline two methods for uninstallation:

1. Using ADB (Android Debug Bridge)

ADB is a tool that allows access to a device’s Unix shell, enabling the execution of commands. By utilizing ADB, you can remove the Carrier Hub app permanently. Here is a step-by-step process:

  • Go to your device’s settings.
  • Tap on “System” and then “About phone.”
  • Tap the “Build number” section seven times to activate the developer options.
  • Once activated, open the developer options (located in the main settings menu).
  • Turn on USB debugging.
  • Download ADB on your PC and extract the file into a folder.
  • Open the extracted folder, press and hold the Shift button, then right-click in a blank area.
  • Click on “Open PowerShell window here.”
  • Enter the command “adb devices” to verify that your Android device is connected to the PC.
  • Connect your Android device to the PC using a cable.
  • Run the command “adb shell pm uninstall –user 0 com.sprint.ms.smf.services” to remove the app permanently.

2. Using System App Remover (Root Needed)

If your device is rooted, you can use a third-party app called “System App Remover” to uninstall the Carrier Hub app. Follow these steps:

  • Download and install the “System App Remover” app.
  • Launch the app and search for the Carrier Hub app.
  • Check the box next to the app’s name.
  • Tap on the uninstall button to completely remove the app.

Note: System App Remover requires root access to your device. If your device is not rooted, you can find methods online to root your specific device model.

Preventing Data Tracking by the App

If you are concerned about the Carrier Hub app accessing your usage data, such as the apps you use and their frequency, you can disallow the app from tracking such information. Follow these steps:

  • Go to your device settings.
  • Search for “Usage data access” using the search bar.
  • Find and tap on the Carrier Hub app.
  • If the usage access is turned on, toggle it off using the button provided.


In conclusion, the Carrier Hub app provides essential features for T-Mobile users, such as VoWi-Fi. While some users have reported issues like battery drain, high data consumption, and negative performance, these problems can be resolved by employing the suggested solutions. If the app is not causing any problems on your device, it is recommended to keep it installed. However, if you wish to uninstall the app, you can utilize the ADB tool or System App Remover (if your device is rooted). Additionally, you can prevent the app from tracking your usage data by disabling the usage access in your device settings.
