What is Carrier Hub? Know Everything About the App [2023]

Carrier Hub is an official app of the T-Mobile/Sprint network that helps establish connections with the cell towers and provides necessary network features such as Voice over Wi-Fi, Secure Wi-Fi, etc. Users using phones that operate on these two networks often notice this app running continuously in the background and wonder whether it is a valid app.

Well, Carrier Hub is a genuine service-related app that is required when using certain network features on T-Mobile or Sprint. Its main function is that it helps connect with the near cell tower so you can have better network strength for calling, using the internet, etc. In this article, we will explain the Carrier Hub app as well as provide solutions to the problems encountered by its users. Let’s begin.

What is Carrier Hub?

It is a Sprint/T-Mobile network-based application that is a must-have app when using the network on a phone for better communication over call, Voice over Wi-Fi, internet browsing, enabling Secure Wi-Fi, etc. The Carrier Hub app continuously runs on the phone and helps provide a good experience by well connecting you with the nearby cell tower. It is also engineered in a way to provide fixes by customer support regarding your network-reported issues.

Moreover, Carrier Hub comes pre-installed on some phones, and in case it doesn’t exist on your phone then you will be prompted via a sticky notification to install it from the Google Play Store or Apple Store (if you are an iPhone user). There are two versions of it available on the app store, Carrier Hub by Sprint and another one is Carrier Hub Magenta by T-Mobile USA. You can simply use the Carrier Hub because Sprint merged with T-Mobile on 1st April 2020.

Why You Need Carrier Hub App?

The Carrier Hub app becomes important for users using Sprint or T-Mobile networks because it enables useful features that enhance the overall user experience of using the network. However, by installing it on your phone, you will have Voice over Wi-Fi that will allow you to call anybody over Wi-Fi. This type of call usually can’t be traced by your network operator since it uses the internet instead of the cell tower for calling.

Another reason why you need the Carrier Hub app could be the Secure Wi-Fi. It is a privacy-centric feature that provides end-to-end encryption between your device and the Wi-Fi connection. This is considered more secure and private Wi-Fi because it is not only password-protected but the connection is also encrypted.

Moreover, aside from useful features, Carrier Hub is necessary if you are on Sprint or T-Mobile network as it maintains the network strength and also helps connect to the nearest cell tower so you face fewer call drops, and surf the internet without hassle, and get better video call quality, etc.

Issues Carrier Hub can Cause on Phone

Carrier Hub is not the most stable network-related app, especially after its new update for fulfilling the Android Q requirements. And because it is not stable, it can cause several issues to arise on your phone that can disturb your day-to-day phone use. Here are the issues commonly faced by Carrier Hub app users.

  • Call Dropping – A good number of users have reported the frequent call-dropping issue caused by the Carrier Hub app. Most of them stated that after switching to a different cell tower connecting app, the call-dropping issue disappeared.
  • Text not getting sent – Carrier Hub also have been blamed by tens of people on its app store review section that text not getting sent after the latest update for compatibility with Android Q. They mostly said that after tapping the send text button, it doesn’t go through and in the end, we receive text message sending failed.
  • Broken Network Switching – Another issue that we have seen mentioned by many is the network switching is not working. Usually, we can switch network modes to LTE, 3G, or 2G but users reported that they are not able to switch between network modes.
  • A decline in Phone Performance – Carrier Hub is a network management app that consumes a good amount of resources on phone. Even when we minimize it and remove it from background apps, it still runs continuously. Due to that, our phones are lefts with fewer resources which cause slow performance when we try to do other things on our phone.
  • High Power Usage – A user of Carrier Hub named Kitty Yescalis recently reported on 11 July 2021 that in his phone around 84% of background power usage resulted from the app alone. That is actually a massive number and clearly shows how power-hungry this app can be. People have also reported about their phones started to give less battery backup ever since they installed Carrier Hub app.
  • Affects other apps – As per the statement of a user named (leah e), the newest version of Carrier Hub has the ability to display over other apps that can interfere with the functions of other apps and make your experience of using other apps worse. Furthermore, the user stated that “It can also modify system settings. Even turning off these settings in the app, still causes issues”.

There are quite many negative effects of using Carrier Hub and the issues mainly have started to pop up after the recent update for compatibility with Android Q. Still, with proper configuration and customization one can handle or at least minimize the negative impacts of it on their phone.

Carrier Hub Processing Requests Explained

Carrier Hub Processing Requests
Carrier Hub Processing Requests

Carrier Hub is not one of the silent apps, it actually does notify about pretty much everything it does in the background such as letting users know when it is trying to connect with the cell tower. So, basically, most people mainly notice two processing requests from Carrier Hub on their phones, let me explain them one by one.

Mobile Requests are Processing

It is a kind of notification that appears through Carrier Hub when suddenly your T-Mobile/Sprint network loses connectivity with the cell tower and couldn’t able to reconnect after several attempts. “Mobile Requests are processing” notifications won’t be cleared away until you get reconnected again. This is an uncommon notification that users encounter when there is maintenance going on or when there is no cell tower under the radar.

MCM Client Requests are Processing

Mobile Content Management (MCM) Client requests are processing notification, which appears quite many times on the user’s phone. It is common as it appears mainly when a user restarts their phone. Once the phone is restarted, Cellular reception is achieved by connecting your phone to nearby towers and from there, the notification goes away. If somehow cellular reception fails, the notification will still show up until the connection is made.

These two notifications have started appearing since the delivery of Carrier Hub and a few other clients by OTA update to users using the Sprint/T-Mobile network. If in case you want to get rid of it, there are some workaround that you will need to perform.
