I am in the military and stationed in Korea. Before I left the states I had the Lg Optimus G Pro with AT&T that i purchased legitimately through them. When i found out I was going to Korea I asked AT&T for the unlock code for my phone which they provided along with instructions. When I arrived here I tried the code and it worked, however I was unable to access the Korean carrier network (Olleh) so I just bought a Note 3 from them. Fast-forward 2 months and a friend asks to try my G Pro on his carrier (LG+), and I reset it and give it to him. However, upon turning on the device he gets the MM #6 error. I own the phone, so I know it's not reported stolen or lost, and I even checked a blacklisted IMEI site and the phone isn't blacklisted. So, why the error. and what can we do to fix it, if anything?

Using AT&T with the Nexus S GT-i9020T?
Has anyone successfully done this?
I bought this model of the Nexus S recently, and have been really enthusiastic about the build quality of the device. However, actually setting up phone service has presented a few challenges.
I have found nothing but conflicting information about this all over the internet. The official Nexus S manual spec sheet seems to imply that the phone can play either the tri-band or the quad-band game. Some folks report that the phone will work with AT&T but will only allow you to use EDGE and not 3G service. There are websites which say that the phone can be unlocked, however, many posters here on the xda-developers forum say that the phone is always unlocked anyway.
I bought both a T-mobile simcard and an AT&T simcard. The T-mobile one works just great. After inserting the AT&T card, the phone sees the local AT&T cell tower, but when trying to connect, it says "Your sim card does not allow a connection on this network."
I took the phone into an AT&T store this afternoon and the customer service rep replaced my sim card - but the phone acted just the same. He told me that the phone was probably carrier locked - and that I could look for a shop to help me unlock it.
So what can be done? Will T-mobile give me an unlock code? Do I need to buy an unlocking code from some vendor on the internet? I am familiar enough with Linux to edit files on the phone using a hex editor if there's a way to unlock it that way (I read about this method in a conversation on xda-developers.com pertaining to the Galaxy S I9000).
Not sure about unlocking, but I do know the 9020t will only do voice and Edge on At&t.

Hardware is not capable of ATT 3G but all nexus devices should already be sim unlocked. Idk why you're experiencing that issue.
I really doubt the att Rep has any knowledge on the tmo nexus s, but I'm really suspecting att's similar card as the culprit, despite the fact that u replaced it.
Sorry I couldn't be of much help.

So... An update on the progress of my quest:
I called T-mobile today (on the phone: "611") where a customer service person tried and failed to authorize the unlock code. She then gave me a service number at Samsung to call: (888) 987 4357. Samsung took the information from me about the cell's phone number and the carrier... and after a bit, bounced me back, saying that I needed to call T-mobile again to see whether I could get them to issue the 8 digit "network control code" which can be derived from the IMEI number.
This time, the T-mobile rep said that she would submit a formal request for me that might take between two days and two weeks to process. She warned me that because I had not had the T-mobile account for 60 days there might be a problem with the approval - but that they might be able to do it, if I offered proof of purchase for the phone (proving that I paid full price for it). She took my email address, my landline number and some other bits of information from me, and promised I'd hear back in a few days.
For those who are interested in all the gory details... here's an update on the hoops I've been trying to jump through:
www . christophervandyck . com / o / node / 412
I lost my phone in November while out at sea and bought a second hand one in Mexico. A Sprint Galaxy S4 L720 running 5.0.1. It was unlocked and running just fine on a Mexican carrier. I bought a new SIM in Peru today and noticed the data wasn't working, phone calls were fine. I then did something very stupid and entered in ##72786#. The Sprint hands free application won't validate the phone. I tried calling Sprint and they informed me that the phone I bought was lost/stolen and refuse to help me.
I am in Peru right now, I cant return this phone to the previous owner and I already spent $250 on it. I don't live in the USA. This is not a matter of ethics in this case, I simply can't eeturn the phone to the carrier. The phone was unlocked before, how can I get back to how it was. It is telling me invalid SIM now and I can't make calls. Is there some way to bypass the activation process?
Thanks
If the phone has been reported lost or stolen to the carrier, you will not get help in these forums on how to activate it.

hi Lg stylo H 631 t-mobile
ihave code for unlock network but when inter 2945#*631# show nothing
try device unlock for t-mobile to unlock till me is faild
how how can enter code to unlock ??
i have to code NCK & SPCK
You should have an app to request a carrier unlock. If the T-Mobile and the MetroPCS devices are essentially the same I don't see why this would not be the case. My MetroPCS LG G Stylo has the app on the home screen in the folder which contains all of my MetroPCS apps. I've actually been fighting with support about getting mine unlocked prior to the 90 day policy for use when I am in Germany.
I have problems unlocki ng my phone i bought someone off craigslist with a lock. On it cani get some help to google unlock this acct so i can activate my phone
Good luck trying to unlock the Style H631 with T-Mobile. They are a bunch of lying manipulating thieves. My mother bought the phone from T-Mobile 2 years ago, she was paying $65.00 a month ($15.00 included for phone payment). I told her to go with H2O, Cricket or AT&T, which have he best reception where we live. I told her to unlocked network her Stylo, we tried by codes by purchasing from online unlock companies, didn't work. I told her to contact T-Mobile and asked for an unlocked code since she was with them for 2 years and never miss a payment. They told her that she needed to pay the remainder of the phone in order for them to give them an unlock code. She did, it was around $120.00. At the time, they gave her a receipt and gave her a number to call. She called and told her that it can't be done because she already unlocked 2 phones in one year, and they only unlock one phone per year. It doesn't make sense, it was her first time unlocking a phone with T-Mobile, she then replied to them, if you can only unlock one phone per year, then how come it shows 2 phone in one year?
If you are with T-Mobile, you are simply out of luck, and the app to unlock is just an app that will display "device can't be unlock" or something along those lines. Best of luck.
Samsung Galaxy S6 Edge +, T-Mobile. I called T-Mobile to have the phone unlocked so I could sell it. Should be a simple procedure. . .but they are unable to do so because they claim the IMEI number is not registered with them and therefore it isn't a T-Mobile phone. The box it came in says T-Mobile, when it boots up the T-Mobile logo appears, I am using their network to call and text, my bill shows the line is active and working, confirmed they have the correct IMEI number. The phone rep said it is a Samsung issue and to call them. I did, and was abruptly told they have nothing to do with unlocking the phone and bounced me back to T-Mobile. . .who just told me they will put in a request for tech support and I should hear back from them in 5 days. WTF?!
What's a guy to do??!

Did you buy the device new or used?
If it's used, are you sure it hasn't been flashed with the IMEI from a different device? Are you sure it isn't a non-Tmobile device that has been flashed with Tmobile stock firmware?
Sent from my SM-S903VL using Tapatalk
The phone was purchased direct from Samsung. It has never been flashed or altered in any way. When I contacted Samsung they confirmed that the IMEI I gave them shows in their database as a T-Mobile phone. So all fingers point to a screw up of some kind with T-Mobile.
I purchased my phone as "brand new" and "unlocked" in December 2021 from an Ebay store (I know, but the store was operational for a couple years and had excellent reviews numbering in the 4Ks). I registered the device IMEI with Samsung the same day. It worked perfectly for 13 months until last week.
Unfortunately, the Ebay store is no longer "there" (I know. I know.) I learned this by attempting to email them through the Ebay messaging app. I really do believe my phone was brand new though.
Device Details:
Model #: SM-N986U1
Service Provider Software version: SAOMC_SM-N986U1_OYM_TFN_12_0016_TFN/TFN,TFN/ATT
Questions:
Was someone able to set up an account with my IMEI
Is it possible that my IMEI was mistakenly connected to an AT&T account during these "Network Upgrades"
If either 1 or 2, how do I resolve this? I mean, I've got the receipts and whatnot.
Is there a way for me to find out if this AT&T account was set up AFTER December 2021?
Do you see any issues with the current software listed above
Could I have registered my device's IMEI with Samsung if it was already registered to someone else?
The whole, ugly story:
My carrier is StraightTalk/TracFone with Verizon SIM (12+ years)
Activated device 1December 23, 2021 by swapping SIM from existing phone (I now know this is bad)
Stopped sending/receiving calls January 3 or 4, 2023 (still able to text w/o wifi though)
Many, many customer support calls/chats:
Unable to reconnect device to SIM
Carrier tech support tells me "Problem with your SIM. It was used in another device. You need a new SIM".
Purchased new SIM, phoned in to carrier support
Carrier support unable to connect new SIM to device
Carrier tech support tells me "Problem with your phone" and asks for me to turn phone off/on every hour or two until they get the "errors corrected".
Support also that many people had been having problems since the recent Verizon network upgrade that occured in the days leading up to my phone problems.
Problem persists and worsens
I lose all connection with my phone number; unable to text, phone number missing from phone, etc
Subsequent support calls with StraightTalk
Your IMEI is connected to a different phone #, cannot reconnect your device.
They won't tell me the number, only that the new number has same area code as my number which I thought unusual.
In order to keep my phone # active, I settle, temporarily, for activating new SIM into my really old S7.
I contact Samsung Support to see if there is some sort of diagnostic tool for software errors:
Your device is an AT&T device
I said I realize that, but it was unlocked and I'd been using it for 13 months with a Verizon compat SIM.
They suggest I visit Samsung Auth Shop to diagnose.
I attempt to reach AT&T support line;
no luck - kept bumping up against phone bot "firewall" system because I didn't have an AT&T phone number or account number to enter.
Attempted support chat, but same results as above
Went to the Samsung Authorized repair shop.
Shop was like "Absolutely nothing we can do"
Says that a diagnosis would not reveal software issues (is this true?)
Suggests I go to AT&T corporate store.
I visit AT&T store, ask for them to check my IMEI for an account.
They cannot find it connected to an AT&T account.
Have a nice day - Buh Byyah (grrrrrr)
Out of frustration, I decide to run the AT&T unlock request app anyway.
Results: Unable to unlock my phone because I still have installment payments to make. (Never had an AT&T account).
Back to the AT&T store.
They dance around suggesting that I have a stolen or hacked phone.
They give me tips on how to bypass AT&T support firewall to reach customer service
Suggest I go across the hall to the Verizon store

I nearly burst into tears and give her a hug
Unfortunately, within a couple hours it was back to no service
I FINALLY get through to a person at AT&T support.
They are able to confirm my device IMEI is connected to an AT&T account
They further confirm that the area code is same as mine and that the phone number belongs to a business.
No further details; they give me their Fraud Dept phone numbers.
Fraud department cannot (WILL NOT) help me because I don't have an AT&T account and I didn't purchase my phone from AT&T.
Have a Nice Day, Buh-Byyah (grrrr)
Finally able to connect once again with support person from my carrier (StraightTalk/TracFone on Verizon)
NOTE: Something def DID happen with their networks early last week. No idea what, but I was once number 410 in the queue for support
Support tells me I need a new SIM
I explain that
We already tried that 4 days ago, and
My device IEMI is connected to another account, per their support rep, AT&T support rep, and AT&T unlock request app
Support tells me to ignore that, I only need a new SIM because:
She wouldn't be able to see my IMEI if it were already connected to another account.
She could see that my IMEI had been connected to my StraightTalk account
There must've been some kind of 'mistake", and a new SIM will fix it
They're mailing me a new SIM, but I don't understand how/why there is an At&T account with my IMEI and have little hope that this will work.
Sorry that was so long. Please respond if you have any helpful tips, insights, or info.
Thanks!
PROBLEM SEEMS TO BE SOLVED
**I'm making this reply for reference in case someone else comes across a similar issue.
My device is a Samsung Note 20 Ultra 5G; my carrier is Straighttalk (TracFone) with a Verizon SIM. I’ve been with them since bailing from Verizon around 2010. I bought my phone from an online store, supposedly "new" and "unlocked". The CSC and Provider Software version checked out, and I was able to register it successfully with Samsung December 2021 and had zero issues with phone and service until Janury 3/4, 2023.**
1/12/23 UPDATE from OP: After 8-9 days of frustration, hours on phone and chat support, in person visits to mobile carrier stores, (oh, and no service), I successfully installed and activated a new SIM on my Note 20 Ultra 5G tonight. Calls, texts, etc., seem to be going through. So, so far so good.
This was my 2nd attempt at reconnecting my device to a network by installing a new SIM. I can only guess at why it was unsuccessful before. But for posterity, the 1st attempt was made by using a SIM kit purchased from Walmart. The 2nd attempt was made by using a SIM purchased from Straighttalk and patiently waiting four days for delivery.
Both attempts were made while I was on a support call, using a landline to speak with them.
After activation today a new feature appeared in my Mobile Networks setting that wasn't there before. It's labeled "VoLTE Calls SIM 1" feature and has an on/off slide button next to it.
Also, my Network Mode was automatically set to GLOBAL after activation, when it had always been set to LTE/CDMA. I'm curious about that, so if anyone wants to chime in on whether GLOBAL is the preferred setting for me now I'd be happy to hear opinions.
I generally have really poor service at my home (1-2 bars usually) and that is still the case. I should be able to access 5G in areas where it's available though.
Ongoing Issue: I do not have proof of resolution regarding my IMEI being connected to another phone number on an account with a different carrier.
As of this evening the IMEI unlock request portal at the other carrier still shows that my IMEI1 has some sort of financial committment attached to it. Interestingly, my IMEI2 is good to go so far as the same unlock portal is concerned. (I’ve never had an account with this carrier) It's a puzzle and I don't know what any of it actually means.
We'll see how things go. Fingers crossed that I'll continue to have uninterrupted service, but it is going to take the passing of some time before I feel like I will be able to relax completely.
Thanks for providing this space for people to problem solve and share.
