Carrier Hub MCM client requests are processing messages

I just purchased a new Motorola One 5G ACE from a TMO store and this app is installed and running all the time. This phone came out only a month ago on TMO and came with a TMO Sim card. So I am not sure if its only needed for Sprint customers. Maybe when a phone roams on sprint towers?

I am able to send text messages but not receive them. I can make and receive calls fine. I also see carrier hub messages popping up and even tho I have tmobile I have a sprint hub on my phone. It won't let me download the tmobile magenta hub. Anyone know how to fix my text messages not coming in?

I hope that I can help. I am using an unlocked Samsung Note 9 that I brought to T•Mobile from the sprint merger. I do have a T•Mobile sim card. The MCM client is usually the carriers way of updating their apps on your device or any specialized software that came pre-installed. I noticed my MCM client running for 10 minutes yesterday and knew I needed to put a stop to it. When I pulled down my notification screen I noticed that the secure folder logo was on the right hand side of the notification. Even if my secure folder was off it was still running in the background. In my notification tab I have a secure folder icon. If you have this icon open the secure folder and pull up your list of apps you should see carrier hub and a chess piece as its logo. Click on the chess piece it will open the information of the app. I do not allow any permissions from this app to go through my phone that is why it's just fact it would not stop running. All I did was clear cache clear data and pushed force stop. MCM client was no longer there and has not come back. I am unsure of what this will do to your phone but it did nothing to my phone even though it said please beware. It only says that because it's a systems app but does not normally have anything to do with how your phone works or handles itself. Although once again I am not responsible for anything that might happen to your phone. Good luck. Let me know if it works

My S20 just updated, and I noticed that carrier hub was pretty constantly running.  I looked through some answers and was able to go to google play store and uninstall it from there.

Update to my last post: I was still receiving the carrier hub notifications.

So go to phone settings, apps, AppSelector app, and UNINSTALL. 

So far no Carrier hub notifications.

If you dont want to uninstall the app, you can stop Carrier Hub notifications. Go to Settings, Notifications, find Carrier Hub, turn off notifications.

the site here is mainly peer to peer with a couple moderators to keep things civil...no agents im afraid.

I’m having the same issue.  and all I can say is WOW.  It appears as though the Uncarrier is uncarriering itself from it’s customers as well.  Very disappointing that our service provider can’t even chime in with any advice or direction about this.

For the past week my phone is constantly restarting, and the MCM message always appears after the restart. I don't know if it's the cause of my phone problems, but that the message is accompanied by the near constant restarting is making me start to hate both equally. WTF is going on?

Ok so this is going to be a very technical answer. The Carrier Hub is a nightmare to deal with and was causing all kinds of problems on my phone. You can’t remove it using the normal methods so here is how you do it using the only if you know what your doing methods.

First you need to unlock developer mode on your phone this is done by going to setting and tapping on the build number of your software until it unlocks it.

You will then need to have access to a computer and down load the android SDK Platform Tools

https://developer.android.com/studio/releases/platform-tools

You will then need to open a command prompt (as admin or root) to where these tools are installed. Connect your phone to your computer when developer mode enabled and then run the command

adb devices

This should prompt for your phone to trust your computer.

Once that is done and your computer can see your phone you can run this command

adb uninstall --user 0 com.sprint.ms.smf.services

That will remove the Carrier Hub app from your phone. I would then reset your network connections (found under reset options) and reboot your phone. This fixed all the network and texting problems I had.  

Just tried, no change at all. 

Same device, same exact issue. MCM Client processing requests on every reboot, chat features in Google Messages refusing to verify me (after being verified for the past 5 months), delayed receipt of messages, stuck sending messages for hours without actually delivering. I cleared carrier services local data, cleared Google Messages local data, reinstalled Messages, multiple reboots, nothing has fixed it. 

My phone finally corrected itself (so basically almost 24 hrs later from when the issue started).
