If you are an Android user, especially with a Sprint or T-Mobile network, you might have come across the Carrier Hub app. If not, you might get a notification to install the app. So, you may wonder what is carrier hub app and what exactly to do with it.

So, in order to put all your doubts about the app to rest, we will cover every aspect of it right here.

Though the app is pretty much stable, still most of the time it can cause you some troubles too. As it is better to fix the issues before they can affect your device, we will review some workarounds. And we will also cover its uninstallation process in case you decide to get rid of it.

So let’s get started without more chit-chat!

What Is Carrier Hub App?

Carrier Hub is an Android app that allows users to place and receive calls over Wi-Fi or wireless internet connection. And if you are a T-Mobile carrier user, this app secures Wi-Fi on these devices.

If you have this app pre-installed on your phone, you can use it to make calls over a Wi-Fi network with your phone number. Sometimes the app might not come pre-installed on some devices. In that case, you can install any of its Sprint or T-Mobile versions from the Play Store.

Is Carrier Hub Necessary?

It is not a must to have the Carrier Hub. But you can keep or install it to enable some user-friendly features.  If the cellular network in your area is not strong enough, this app can come in handy. Because the Voice Wi-Fi calling feature uses Wi-Fi instead of a cell tower network to make calls.

When the app crashes most of the time it fixes itself with the usage data. It tracks the data on your phone to resolve the frequent or random stops. So, as long as the app is not giving you any major issues it can be pretty necessary to make your calling experience better.

Does the Carrier Hub App Cause Issues on Your Phone?

It cannot cause any severe damage to your phone. But some of the users have reported that the Carrier Hub app keeps crashing or stopping in between. And other than that, there are a few more issues listed below

1. MCM Request Notification

If you live in an area where cell tower connection drops frequently, you are likely to receive MCM (Mobile Client Management) processing request notifications. It happens when the phone cannot connect to the tower network.

This notification pops up after restarting your phone also. But it disappears when the phone connects to the T-Mobile network.

2. Battery and High Data Consumption

While operating the app, the battery comparatively dies faster. Even if you keep the app running in the background, it will drain your battery life sooner. However, the issues reported by the users do not specify how much battery percentage this app consumes.

Some users have also reported that the Carrier Hub app is likely to consume more data than any other app. So, it quietly kills your data plan.

3. Poor Performance

The Carrier Hub can sometimes make your phone laggy. Also, your phone can freeze at times, especially if you use the outdated version of the app.

Your phone can operate slowly if the latest updates of the app are taking too much storage space. However, upon restarting the device this issue disappears most of the time.
