DCB_ASSOCIATION SMS Text?

Hey guys I was just reviewing my outgoing text messages and saw an out going message to this following
TO: 1505
Message:
DCB_ASSOCIATION: <appears to be an md5 checksum>
I am on TMOBILE USA
I did a google search and it looks like another n5 user, on tmobile, posted this the other day as well.
I had my buddy, who is on his n4 look and he did not see this.
I am ASSUMING this is calling back to TMOBILE for possibly a phone description? I am not sure though.
Anyone else?

I got this today right after I sweet up carrier billing in the play store. Also on T-Mobile and Nexus 5.

This just happened on my Nexus 4 with 4.4 from the Google factory image. I'm on T-Mobile and used carrier billing to buy a app too.

Carrier billing verification - on Sprint. It's not just a T-mobile thing.

Confirmed Google Play Store Verification

So I was able to confirm that this is a text message sent via your Carrier to confirm that you would like to charge an App (or Play Service) to your Phone Bill.

CAREFUL!!!l...perhaps someone might consider publicizing this information. To protect others?.
I pasted the url in my browser ... I found myself on Verizon. The responses were the same. Is it some sorry of security breach? Does anyone know?
I just couldn't stop thinking about it. Especially because I left this afternoon. It's now late night and everybody is still talking about the same thing.

I got it on a t mobile phone after downloading and installing modded play store after trying a purchase using t mobile billing. The sale failed, but I still got the message. I know lp isn't a great subject to bring up here, but the purpose of this isn't to steal software, it's to identify a problem.

Yes, I also have T-Mobile and saw that on my phone. Seems the msg was sent while I was asleep.

Yes
I recived message like this: DCB_ASSOCIATION:Wu7ef0Cnmkf8dTFzHfxKxAFU. And i wqnt to know what it mean . BTW my operator is O2-SK

I got this out going text on my galaxy s3 note.
Does any one know wat it means or why my phone is auto texting by itself?

Did you set up a payment method on Google Play with your mobile operator?
Sent from my Nexus 5 using Tapatalk

I just looked this up as I had the same outgoing text. It is a SMS sent to your carrier when you set up and possibly every time you make a carrier billing purchase. Nothing to be scared of.
Posted with the official XDA Developers app for Android.

My phone sent an sms to 9210 that read: DCB_ASSOCIATION: followed by 24 random upper and lower case letters. This was right after I authorized google play to bill my carrier for purchases. It was an automated text to Sprint confirming carrier billing authorization.

Confirming that I got this from Google play store, going to AT&T, but for a 0$ item. Really don't understand why i have to provide it for a 0$ eBook. But...meh... It's not malicious afaik.

I just got this tex an i think its a phone tap or phone tracking ive sent simaler things to people in the parst

It's a message from T-Mobile when they get a request from Google play to add T-Mobile as a billing option. The first part "DCB_ASSOCIATION:" tells you that it was to make an association with your phone account.

Its because you have T-Mobile and you used your T-Mobile account as a payment option. They text your phone to verify...Its just a dcm from T-Mobile...the code received possibly means if it were excepted(regular account).. Or didn't (prepaid..pay as you go)

UICC Unlocked?

I woke up this morning to a message on my screen saying that my UICC has been unlocked. I am stock unrooted. The only mod I have done was add ",dun" to unlock my hotspot. I wish I had taken a screenshot of the message before I cleared it, but I didn't. Has anyone else experienced this? Is it a problem for me?
Thanks for any input.

I'm not 100% sure but I think that's the message you get when your Note 5 is unlocked to be used on an international carrier.

Before I posted, I searched and saw similar results. But I haven't changed my plan nor have I contacted Sprint to make the request for international travel. I just wonder why it automatically did that. I am going to restart my phone and update profile to see if it resolves and/or happens again.
*** When I went into the settings to update the profile, I see UICC Unlock. Out of curiosity, I clicked it and got the same message as before. Must not be as big of a deal as I thought it would be. Still wonder why it did it on its own.

NumberSync S3 on AT&T

I'm unable to get it setup on my Note4. I get the incredibly useful message "Backend error" from the AT&T site after I enter the sync code on their site.
Is this a temporary issue you think, or is it just the usual incompetence of an inept software developer who can't be bothered to give meaningful results to help narrow down the cause of an error?
Is it working for everyone else?

Yep, getting the same error message. Hope this is temporary!

I was having a similar issue. On my Gear S3 when trying to get the sync code, it kept giving an error message. Finally after 9:30 central time I was able to generate the code and get it synced. I think the system was overloaded with all the at&t pre-orders being delivered yesterday.

Anyone have AT&T S3 but linking to S7E 935F International phone? Keep trying to set up Numbersync but it connects to my wife's 935A. It won't see my phone. I am running Hydra Rom but the watch is connected with Bluetooth no problem.

For numbersync to be setup, you have to have a username for myatt for that exact phone. Then it will allow you to setup numbersync if that phone is HD voice capable.

I set it up on my Axon 7 without any problems.

Just tried again, same error message

According to AT&T International S7E (Exynos) is not compatible with LTE Frontier watch on AT&T due to no HD voice? Can use Bluetooth, but not the Numbersync. I'm pretty PO'd right now as that was why I bought it.

Anybody getting this to work yet?

I have not been able to get it to work. I am using an unlocked tmobile note 4. When I called I was told it was because it was not an at&t phone. What if I change the build prop to 910A from 910T? Would that be enough for it to work? Dont want to try and mess things up.

Hi I'm new to this forum. Like OP, I also have a Note 4 ATT LTE and had the same Numbersync error. Here is how I resolved my issue after extensive research:
1) Make sure to enable HD Voice on your phone if supported (for Note 4: Settings->More networks->Mobile networks->Mobile data->check Enhanced LTE Services (mine was unchecked)
2) Before even attempting to sync via Numbersync, make sure that your cell phone number is set as primary in My ATT account. I didn't have a primary number set, so I tried making the Gear S3's number primary (when I was prompted to add one) and it didn't work properly. So I learned it's essential your PHONE (the one you intend to connect with S3) is set as primary, NOT another phone/tablet/wearable line in your account.
3) After all the initial errors and hassles thereafter, I just reset the S3 after following my above instructions and the sync was seamless and I was up and running.
Hope this helps...it certainly worked for me!

Is your phone stock? Rooted? Custom rom? AT&T branded phone?

Yes! That worked, thank you!

The red pointer is for the chronograph function. It does not move unless you tap it to start the chrono. Bad design in my opinion.

Soo no one here might have an iPhone they were able to get numbersync to work on with the leaked iOS app?

Has anyone got Numbersync to work on International S7E 935F?

I have number sync working with my Nexus 6P, spent about an hour in the AT&T store working with the salesperson that sold me my Frontier. He was under the belief that it was tied to IMEI numbers so he supposedly cloned my wife's IMEI number to my 6P which didn't work. I told him that I read that HD Voice/VoLTE had to be enabled and because I had a Nexus 6P that was the problem. So he called support and asked them to enable HD Voice on my line. While he was doing that I was googling, found this thread: https://forums.att.com/t5/Device-Features/Nexus-6P-No-HD-Voice-and-Wifi-Calling/td-p/4346076 and followed this guide:
Navigate to Settings > More > Cellular Networks and enable the toggle switch for "Enhanced" 4G LTE Mode. However, if the toggle is missing then follow the steps provided below:
Launch the Dialer app on your phone, and dial*#*#4636#*#*.
Choose Phone information.
Enable or select VoLTE Provisioned Flag.
Restart the phone.
Go to Settings " More " Cellular networks and toggle the switch for Enhanced 4G LTE Mode, and the HD Voice calling feature should now be activated on your device running Android 5.1 and above.

I enabled the VoLTE option, restarted my phone and sure enough when I went back into the MyATT webpage I was now offered the ability to enter in a sync code and it worked. He was never able to get support to enable HD Voice on their end. Going back into the setting it shows that VoLTE isn't active, I have no HD Voice option or feature in the Enhanced 4G LTE options at all but my number is indeed synced. I left my phone at home, walked the dogs and made 2 phone calls and the number did go over as my cell number.
Now the other thing he mentioned that should work is to use an approved AT&T phone that has HD Voice capabilities enabled. Then if I were to put my SIM in that phone, wait for the MyATT webpage to update showing that this other phone was tied to my number, then perform the number sync at this point it should also work, once it's enabled it won't go away according to the ATT rep. I didn't need to do that so I can't confirm but it sounds reasonable.

T-Mobile Digits

Supposedly their one number solution works with any carrier.
https://explore.t-mobile.com/digits-landing

Not sure how it works with any carrier when the sign up asks specifically for your Tmobile phone number? Lol I did however read about the beta sign up page leaking people's accounts by a glitch in the system. https://www.xda-developers.com/t-mobile_digits_security/

I went to the site and started to opt in for the beta. It presented me a 10 digit number that was not one of my several T-Mobile lines. I went no further.
About 10 minutes later I went back to the site. They have changed the sign up process. You now just sign up (no data exchange) and they will get back to you if you are selected.
Hope it works as I have 2 smartwatches and a phone line on T-Mobile, plus I have a work phone on Verizon. This could make it easier for me to use one number and not have to worry about setting up call forwarding on multiple devices.

According to Engadget, the app will work with the big 4 carriers. They're not sure about specifics yet.

Hmm well that might be cool then!

Just signed up on mine. My Pixel XL and Gear S3 now use/share the same number

I'm not certain that this is the cause, however, since activating Digits, my S3 doesn't seem to want to connect to the mobile device through the cellular network any more. I used to get all the notifications and now -- nothing. Anyone else experiencing this?
I can't seem to activate the "Remote connection" on the Gear App, so I'm not convinced that the problem is with Digits.
Any thoughts?

Quick update: Much as I hated to do it, a device reset on the S3 and a reinstall of the Gear app on the phone solved it. My guess is that the phone and the S3 device exchanged pertinent info from the esim card that changed when the phone number changed upon enrollment in Digits. Redoing the whole thing, I presume, forced this new information into the equation and solved it toute suite.
If anyone has any additional insight, I'm all ears, but I'm good to go now.

Xfinity Mobile

Hello all, I just activated my Samsung S8+ on Xfinity Mobile this past Tuesday and I still have not received the May security update. I was wondering if anyone read anything about how they are going to push the monthly updates? I have been searching Google but of course because it is so new there is a lack of information.

It hasn't been released yet.

I am curious to see how quick they are on patching, considering the phone has almost zero bloat it shouldn't take long once they are available.

Does your VoLTE work? I have the unlocked version flashed to xfinity and I can't find the VoLTE setting.

VOLTE Works for me on Xfinity Mobile.
Settings>Connections>Mobile Networks
The toggle is there.
I am in same boat as others. I left AT&T. So refreshing to be TouchWiz base without all the major carrier crap/mods.

So you can use data while on a call WITHOUT WiFi being on? Mine shows 3G all the time with WiFi off. I was thinking it was a SIM compatibility issue between the LG X Power and S8+. My SIM from my Note5 wouldn't work in my S8+ on Sprint. Had to have a different one.

It's set to global. I have trouble getting LTE period. I can use Rom Control and force to LTE and web is OK. No calls though. Toggle is missing. Same thing, I can enable VoLTE with Rom Control and can see the toggle. NO voice calls though. Says out of service area. Maybe it's because the LG X Power doesn't support VoLTE and the account isn't provisioned for it. I put the SIM card back in the X Power and I can't get 4G on there now. A tier 2 tech was poking around my account yesterday. Don't know what he did. He hung up on my. LOL

APN settings appear correct. Compared that with the LG. My LG has a username and password though. I take them out and I have no data at all. The S8+ has data with the settings like yours. I can edit the APN settings on the LG where as they are locked on the S8+. Weird since this is an unlocked U1 phone. Had to flash the Xfinity firmware to get text to work though. Hopefully that didn't lock the device to Xfinity. The tier 2 tech wanted the IMEI from there S8+. I gave it to him and he said that was for the LG X Power. I had the S8+ box in front of me and even pulled it from the phone. Still said that it belonged to the LG. Then he hung up on me. Not a word since.

Hmmm, maybe he did you a favor actually.
I just flashed the U1 firmware to my Xfinity device and all the APN stuff is editable. Phone shows as a U1 model too. Everything is working great. I found everytjing in thr AT&T section of S8+.
Can you flash back to U1 firmware, pop the X mobile sim in (get the device all set up first before putting SIM in) and then do a manual search on service provider section of mobile connections? The tech may have locked that SIM to IMEI, but that's a good thing if you are wanting to use that SIM on S8, right?
Go in to network operators and pick top option (search networks) and let it search for a while. Then you should have a list like my second attachment. Oh and don't mind my lack of cell signal lol, I was jacking around with all of the editable options available now.
Be sure and set Bearer to Unspecified (with nothing else selected). Save before exiting. Added third pic to show I am on LTE+ on U1 firmware with X mobile SIM, but this SIM was always tied to this IMEI as it is Xfinity Purchased phone.

Did you ever get this going? I never did get 4G going on my LG X Power. The only way I could get it to work was to select LTE/GSM under mobile networks. Of course calls wouldn't work then. Exchanged them for the LG X Charge which supports VoLTE. I still can't get 4G. They said to use my old sim cards. I think I have a provisioning issue. Still waiting on tier 2 to call.
