mm6 code help

First time poster but have been browsing the forums for awhile.......heres my situation. I bought a used s5 on att that I used for 8 months on straight talks network without issue. moved to honduras this week and trying to get my phone set up on Claros network. Found out the phone was locked because of failure to complete contract from previous owner. Att wouldn't let me pay the remainder of previous customer and gave no helpful suggestions so a had a third party swap Imei numbers to a clean unlocked number from a identical phone (s5 sm-g900a) . new number is clean and unlocked but when I put the claro sim in im getting a mm6 code. Data work with the sim card but no phone\text. swapped back in my old sim card(straight talks) and do not get the code and shows bars for cellular. is this something I need to go back to Claro for( trying to make sure because my spanish is very bad and it takes forever to get things done) to update the imei number in their system or is this something I need to go back to the company that did the imei swap? Thanks For any help or direction as to where to go from there.

Sim Unlock Sprint Galaxy S5 for use on the AT&T Network?

Hello everybody, sorry if this has been asked I tried searching everywhere and have come up with nothing that has been helpful to me. I am new here so if I'm posting in the wrong place I'll be happy to remove this.
I will try to provide you with every detail but my main problem is this: I have obtained an unlock code I received directly from Sprint for a Galaxy S5 I received from a friend. The friend made sure the device and his account met their qualifications, and he received a six digit "MSL Code" that he was told is the unlock code.
I have been told by Sprint, AT&T, countless YouTube videos and forums that the sequence for unlocking this phone is as simple as 1.) Entering a foreign sim into your device. 2.) When you turn the device on you will be prompted to enter the sim unlock code. 3.) Enter the unlock code and your device will be unlocked.
Of course it's turned out to be way less simple than that. My most obvious problem is with step #2. I am never prompted to enter the sim unlock code and instead only receive the message "Invalid Sim card."
Okay here is a back story if you want more details: I am on a family plan with AT&T right now that I believe is a good deal and would not like to switch carriers, although AT&T hires some of the biggest idiots I've ever encountered to work in their retail stores and tech support. I have been tempted to switch to Sprint because throughout all of this they have been the only ones to give me straightforward information and any help at all so far.
The Galaxy S5 in my possession meets all of Sprint's requirements to be unlocked and the previous owner received the unlock code directly from Sprint. It should be good to go.
I went to AT&T retail store with the locked device and unlock code for assistance and to make sure the process would go smooth and easy. The first time I was told it's impossible to sim unlock a phone and all I can do is sell the phone on eBay. I called tech support after this and they told me my problem was that I was using the AT&T sim card from my old HTC One, that SIM Card would be incompatible with the Samsung, so therefore I am receiving an "Invalid Sim card" error. The second time I went in I requested a sim card for a Samsung Galaxy S5 because AT&T tech support told me the SIM card in my HTC will not work. The dude grabbed an empty SIM card and gave it to me without asking me for my information or anything about my account and when I asked him about this he told me that it's not necessary, "SIM cards don't have any memory or carry any information on them for the phone to read other than what service the phone is supposed to use". I honestly don't know much about cell phone technology but I knew this was bull**** but he was no further help after I told him I think he might be wrong about that. I called AT&T tech support and they told me that guy was an idiot and to go back to them and request another SIM card.
I don't want to go back into that stupid store until I'm absolutely sure what the **** I need to do to get this stupid phone to work with my AT&T account. Please educate me on how this process works and what the correct steps I need to take are. Thanks a million times in advance for whatever help you can give me, and again let me know if this is being asked in the wrong place I'm still new here.

Problem changing flashed PagePlus phone to RingPlus

Hi, everyone. I'm new to thie forum.
A couple of years ago I bought a Galaxy S4 from eBay. It was a Sprint phone, flashed to be used at PagePlus, without UICC SIM card, 3G only. It has been working fine on PagePlus (except MMS).
Due to the lack of 4G and hearing the offers by RingPlus, I decided to move to RingPlus. I verified that the MEID and IMEI of the phone on R+ website, they both showed to be fine. So I terminated my PagePlus account, unrooted the phone back to original Samsung ROM for Sprint, and signed up for the Phoenix plan. Everything went well until this point.
I then followed the instruction on R+ website to complete the device activation for Android device (manually provisioning PRL), there's no response when I dialed "##MSL#" (the MSL is correct, as shown on my R+ account). I then tried to perform a PRL update by dialing ##72786#, the phone couldn't be activated. There's a message saying "Because of the type of account you have, we'll need to help you with the task. Please dial *2 from your Sprint phone or call Custom Care at 1-888-211-4727 from another phone so we can assist you."
I checked my MEID and IMEI again, and realized that even though the IMEI does show that it's a Galaxy S4, the MEID is actually associated with a Sanyo 3G phone. The eBay seller must have switched the MEID when flashing it to PagePlus. I didn't realize it until now. When I tried to dial a number using this phone now (after it's terminated from PagePlus), it was directed to Verizon Wireless.
From R+ forum I was told that my current MEID is a "donor MEID". I don't know what the original MEID was. The seller peeled off the sticker inside the phone. I only realized that today too.
So could anyone suggest what should I do? I was told that I need to flashed back to Sprint, but it will be difficult since I don't know the correct MEID. I was recommended to come to XDA to get some advance help. So here I'm.
Thank you very much for your help!

I went through the same process and it was a headache. You need to unflash your phone from Page Plus and reset it back to Sprint. This is going to take more than just unrooting and flashing a stock ROM.
I don't remember the exact instructions but you should Google "flash page plus back to sprint" and then look for Viper32's posts about flashing phones. There are instructions about entering ##RTN# in your dialer to reset the phone. Not sure if that was all it took because my experience was that I tried a lot of different things until one of them stuck. But that was where I started.
The easier way is possibly to take it to a Sprint store and have them reset it but I never tried it myself.

Phone Not Allowed - UK SM-G950F

Hi All
I'm at my wits end with this Samsung S8 phone, Bought a 2nd hand S8, was working fine, but I noticed the internal storage was only showing 9.63GB
Had a look on here and the solution was to stock flash the phone. I did that, all fine, storage was back to normal....BUT since then I can't make or receive any calls.
I get the error "phone not allowed" and it won't connect to ANY mobile network.
I've tried loads of different suggestions
Sim is OK in another phone
Re Flashed (numerous times)
Andriod 7 and 8
Sim and Phone OK with three network
But still have the issue....
Can anyone help me? or push me in the right direction?
Cheers
Tommy

You probably tried this, but try booting into safe mode. If it works then there is a software problem. If the problems persist in safe mode you probably gotta contact Samsung.

Are you sure the phone is unlocked?

Is the phone blacklisted? if it is blacklisted then it will not connect to service. Your SIM wil work perfect in any other phone.

Hate to say this but it does sound like your phone has been blacklisted.
You can check with one of the online IMEI blacklists.

If your phone shows Phone not allowed and a code like MM#6, it usually is an indication that it was blacklisted.
Check your phone's IMEI on a blacklist checker like http://imeipro.info/

The previous user most likely had the firmware and baseband messed around with and once you flashed stock it reverted to true state, it's highly advised to get back in contact with the person, where was the phone bought? A shop? Online?

Yeah tried that , still the same

If one is in possesion of a S8 that says "Phone not allowed", and the phone is blacklisted, is there any way of fixing that?
I have the same issue here..
I bought an S8 from Manchester last summer, and I started using it last week, (because my other phone worked longer than expected) and after I gave the phone the Network key that the previous user wrote down for me, then that message appeared.
So im stuck with this almost completely new brick aswell...
Any options at all?

The only real solution here is to either go abroad and sell the phone, or sell it to someone who is going abroad. The phone will work outside of the UK.

It does sound as your phones imei Nr is blocked in UK.. Probably the person who sold you the phone, stole it somewhere.

I have the same problem on my Samsung S7 now in Brazil.
In Canada, on Canadian carriers, everything is fine, and if I put the Canadian SIM in there everything is fine. But the minute I plug in Brazilian SIM card, boom, Phone Not Allowed message comes up and it won't connect to any of the Brazilian networks. Brand new SIM, works just fine on another LG phone (and any other phone I tried).
The phone is unlocked, I even checked with a few pieces of software and there is no network lock on it either.
I've got the master & network unlock codes from Samsung, but have no way of inputting them as no prompts for those come up when I insert the Brazilian SIM.
I checked the IMEI, it is definitely clean and not blacklisted.
Heck, I even rooted the phone to see if that would help, and still nothing.
Any idea what else to try or what else might be causing this goddamn message to pop up?!

I solved my S8.
Blacklisted on all uk networks except Three network.
Works perfect.

LG V20 LS997 successfully unlocked with Oreo update

I finally unlocked my LG V20 LS997 (Sprint version). There is no trick.
I bought my LG V20 LS997 from ebay and the seller claimed it is unlocked. I called Sprint and they also told me the phone is unlocked domestically and internationally.
However when I put non-Sprint sim card, I always got invalid sim card icon in the status bar and cannot get the phone work. Many people had the same issues.
Some people can unlock it and work but after update to Oreo, the phone will be locked again.
I found place in Sprint community talking about the unlocked LG V20 but still getting invalid sim card. I read through all the articles one by one. And I found that there are basically three steps:
1) Update PRL;
2) Update Profile;
3) Unlock UICC;
I can do the first two without any problem. But I never succeeded in step 3. So in Sprint community, I sent Em_Will_I_Am (please remember this guy, he is really good and can help you out) a private message telling him my IMEI, ICCD(sim card) and what problem I had. He will check if the phone is unlocked in the system or not first and make sure the phone can be unlocked by Sprint standard (fully paid, not stole phone, no unpaid charge etc.). Since my phone is in good standing and can be unlocked. He first re-locked my phone and I had to restart my phone using ##72786# to reset network settings. After that he unlocked my phone. After I do ##72786# again and wait for my phone is hand-free activated and wait for several minutes. I did
1) Update PRL;
2) Update Profile;
3) Unlock UICC;
What I got was something like 'Your phone is unlocked to any UICC that supported by the phone.'
Then I removed my sprint sim card and into a H2O wireless (AT&T MVNO) sim card. It works! You have to manually configure the APN in order to get data working. Since this is Sprint version V20, it only support 3G in at&t network. But at least I can have voice and 3G data from other vendor. I tried rebooting my V20 and factory resetting my V20. All of these operations have no impact on accepting the non-Sprint sim card. It looks to me is really unlocked now. My LG V20 was update to Oreo OTA one week back. so it is on the latest version of android now.
Thanks a lot to Em_Will_I_Am. When he relocks and unlocks your phone, he basically sends out a signal and your phone will pop up and say 'Updating profile' and then 'Profile update is completed'. During the whole process, Em_Will_I_Am will send you private message to tell you what he did and what you need to do.
My LG V20 was still in Sprint network and was active. I don't know if you don't have your phone actively on Sprint network will that work. But I would suggest to send private message to Em_Will_I_Am and seek his help. He may be able to help.

How can I get in contact with him

How can I get contact with him?

I need help too. Bought V20 phone off ebay and it worked great for about 4 months with Straight Talk and Cricket and then it got the Oreo update and now it gives me the invalid SIM message. I never used it on Sprint but it was a Sprint phone. Any help would be appreciated or if you can pass along the way for me to contact the person that helped you that would be great.

I was able to contact Em_Will_I_Am and they helped me out. I think an unlock code was sent again. I also did a couple of things that I think finally allowed the unlock code to come through. I went into developer mode and turned on Enable OEM unlock and then powered off. Then I powered back on while holding the power button and volume down. When the menu came up I chose Wipe Cache Partition. Then when I rebooted it came up and recognized the SIM again and so far all is good. Thanks again to Em_Will_I_Am on the Sprint community forums for all the help.

i paid for a unlock via ebay after he was finish unlocking my phone i inserted my sim. sginal kept droping every few seconds. so i cleared the network settings via phone dialer couple of times, same issue everytime so i just fk it and just updated to oreo now its still unlocked and signal don't drop!!!

Greetings.
I can confirm this. The Sprint assistant knows exactly how to solve the issue in just a few steps. Had the same problem associated to the phone locked since Oreo update and he helped me in a matter of few steps. Create the Sprint account and message him. He'll give you the support.

How long did it take for you to get the support?

I assumed I would need a Sprint sim to do this, so I just bought a new Sprint sim card off of ebay for a couple dollars. Then you will be able to give the sim information to Em_Will_I_Am
He'll put you on the list if your phone is able to be unlocked (ie. not blacklisted, not listed as stolen etc) and soon you'll be unlocked.
I'm so thankful to have found this thread and so thankful to Em_I_will for all his help. Amazingly helpful person.

I have the same problem; Em_Will_I_Am told me that I would be on the waiting list from last week and still no answer.
Could you please tell me more or less what time it took you to complete the unlocking process?

I waited just over a week. Keep in mind, they are done in the order they are received and I'm sure the first priority is dealing with customers actually staying with Sprint
Just keep your phone powered up so that you're ready when your time comes.
