What Is Carrier Hub App? (Explained)

Carrier Hub is an Android app that comes with the Sprint/T-Mobile carrier network. A lot of people are asking questions about the Carrier Hub app like what does the Carrier hub app do, is it necessary to keep the Carrier Hub app on your phone, etc.

In this article, I will explain everything about the Carrier Hub app, its purpose, its necessity and, how to disable and uninstall it.

What is the Carrier Hub App?

The Carrier Hub app is a preinstalled Android system app that allows you to enable features and products like Voice over Wi-Fi (VoWi-Fi) and Secure Wi-Fi for devices operating on the Sprint/T-Mobile network.

The Voice over Wi-Fi feature allows you to use your actual phone number to call others over Wi-Fi. VoWi-Fi calling connects your voice to your mobile carrier’s network using the Internet instead of cell towers. The Secure Wi-Fi feature provides end-to-end encryption for your Wifi call so this call cannot be tracked by the carrier network.

If you check their app description on Google Play Store, you will find that the Carrier Hub app tracks usage data on your phone and uses this data for customer-reported service concerns.

This means if your Sprint/T-Mobile carrier network is giving you problems or the Carrier Hub app is frequently crashing then they can use the usage data on your device to solve your problems.

The Google PlayStore currently has two versions of this app. The first version is the Carrier Hub by Sprint and the second version is the Carrier Hub Magenta by T-Mobile USA. Both these apps offer the same features because Sprint merged with T-Mobile on April 1, 2020.

The Carrier Hub app comes pre-installed on some Android devices using the Sprint/T-Mobile network while in other devices you get constant notifications to download the app for a better user experience.

If you get a notification asking you to install Carrier Hub, you can tap on the notification and follow the on-screen instructions to download and install it.

There have been a lot of instances where users couldn’t download the app because they got a notification “the app failed to download.” If you are getting this error you need to clear your PlayStore cache, phone cache, reboot the device, and then try installing it again.

What is the meaning of MCM Client Requests Are Processing and carrier hub app selector requests are processing?

A lot of users who installed the Carrier Hub app on their device have faced Mobile content management (MCM) client requests are processing notification and App Selector Requests are Processing notification issues.

Users with the Sprint network get the MCM Client Requests are Processing issue whereas users with T-Mobile network have an app called App Selector and it causes the App Selector Requests are Processing issues.

This notification is mostly seen after you restart your phone because after restarting your device, your phone tries to connect to the nearby cell towers for cellular reception and once the connection is complete these notifications disappear.

However, if you are in an area with poor cellular reception where the connection keeps dropping, you will constantly see the notifications appear on your phone.
