Any one else getting "Configuration Notification" messages?

I have been working with some TMo engineers for several days now on this issue. Some light has finally been shed today, although there is still no known solution or work-around. @tmo_amanda, you'll probably want to be aware of this.

So for a few days, the official response was that these messages were not coming from T-Mobile. However, I was able to reproduce them very easily and on-demand by swapping SIM cards from one "affected" phone to another. Not all phones are affected (for example, a Pixel 2 XL is not) but some less-popular brands are (OnePlus, Essential, and ZTE, for instance). I had two different SIM cards and both cards were able to reproduce this behavior on-demand every single time I swapped cards from one phone to another. However, reboots, airplane mode, and other such changes did not cause the problem. I understand this trigger is different than what others see, and that's okay. I think we're still working towards the root of the problem and it's good we don't need weak signal situations to trigger this, which are much more difficult to reproduce. Given that the network detecting that a SIM card changing phones was the trigger for me, this mostly proved that T-Mobile WAS the source of these messages one way or another.

Well, the official response changed today. I am now being told that these messages ARE coming from T-Mobile, and that they're specifically related to DIGITS. We have tried several things to try to manipulate the system to stop sending this messages but so far all attempts (both by me and the network engineers) have proven unsuccessful. So we don't yet have any way to stop the messages, but we are finally on a path that has hope!

I'll come back here and post more as I have useful information to share. It's a little slow-moving, so it might take a while, though. :-)

I should reverify this before posting, but i have a feeling it could be

related to some tower cells or to some in my trajectory during the day.

Previously I blocked 2 or 3 originating numbers, and messages stopped

coming for days as long as I'm in my regular travel trajectory. Today I

traveled out of that familiar area and received one message...

I'm sorry for being absent on the thread guys. I appreciate each and everyone one of your updates that you've passed along to me. If tickets have been filed with Engineers, please pass along those ticket numbers. I'm tracking down a different contact to get this resolved as fast as possible. Continually getting these messages would drive me nuts and I'm sure it's doing the same to some of you. I'm incredibly sorry this is still going on but I'll continue searching for answers!

@magenta5791515 - what number are these messages coming from now since you blocked a few of them previously?

@jaxidian - thank you for being incredibly helpful. I'm going to send you a PM to see if we can get on the same page and make some progress! You can check your inbox aquí.

I haven't contributed to this thread due to not having a profile on here. I've gotten these "Configuration" messages as well. What I've noticed with them though, is that the only time I ever get them, is on my ZTE Axon M (Z999) only AFTER I put my sim card back into the device. I have tried to recreate the same message on my previous phone (Lenovo Moto E 4) with no success. The more I look into it, the message is supposed to provide the proper APN settings with it to whatever device the Sim card has been put into. This is mainly only on devices that don't automatically switch the APN info when you put a Sim card into it. That doesn't explain why it's spamming the other T-Mo users though. The only numbers that I receive the messages from are:

5126

5127

Amanda,

I haven't switched (or even touched) the Sim card on my phone (OnePlus 3T) but I have received configuration notification messages. I have received multiple messages from these numbers: 5125, 5126, 5127, 5128, 5129 & 909. The last multiple messages from the numbers ending in 27 & 28 I received August 10th. All these #s are blocked. Thanks for trying to help us out.

The last time I contacted OnePlus, they also suggested to move the sim card from one slot to the other, and since then, I have not received any more configuration messages.

The sim card is not the culprit for my receiving the messages either. I do not move my sim card, yet I began receiving the configuration messages on July 9th. After calling support, I was told to remove and replace the sim card. This had no effect; configuration message still came in at about one dozen a day. I eventually simply gave up on calling T-Mobile, relied on this thread for additional information, and turned off text notifications in exasperation. That was over a month ago. The messages have suddenly stopped, though, with the last one received on July31st. I even turned my text notifications back on two days ago.

I have never switched Sims either and getting daily messages from these same numbers. 909,5125-29

I called t mobile few weeks ago, never got a ticket number since t mobile did not acknowledge it's a problem from their side.
