I purchased my Samsung S3 from a local pawn shop, I have the receipt and all. I got it home, I use net10 service, popped n my sims card, which I have done many times, the phone worked fine for little bit then I started getting an ATT error message saying "this device has been blocked from network access" I contacted Net10 they changed settings on their end it would work for few minutes then go right back to the error. I have called at&t, cant get thru to the actual customer service (it seems if you dont have an att phone number you cannot get to technical support) had to call the store of course they gave me stock answer, nothing they can do.
Is there anything I can do? would rooting it fix this or is there a program? Unlocking it? help I am desperate, already sold my other phone to buy this one!
SCREWED & IRRITATED:crying:
I would say try unlocking it. at this point it won't hurt.

What version of android is the phone currently on? There are guides here on xda that will allow u to unlock right from the phone if you're on stock 4.1.1. I bought my s3 in May and use straight talk (at&t) and never had issues...
Long story short, I signed up for T-Mobile and ordered a Pixel 2 which will not arrive until a few weeks. I want to temporarily use my Sprint S6 for the time being with the T-Mobile sim card.
I have the Sprint version of S6 (SM-G920P) which I paid off and requested a Domestic Sim Unlock. I got an email that my phone was successfully unlocked, but I'm not sure what they do over the air or will it even work on my rooted S6.
current situation: sim card invalid message when I shove in the Tmobile sim.
Can someone chime in and tell me if this is possible? Will I have to go back to stock before this can happen?
thanks
Oh man
I had the same issue. My nephew threw my TMO phone and it was unusable, so my sister gave me her old S6 since she upgraded.
I did the same as you, had them unlock it, got an email but no way to enter a code or anything, searched forever found out you have to be on the sprint network, so wifi wont work, and no service wont work. Then you have to click the three prompts to update PRL and whatever else then lastly click that UIUC unlock, then they said it will get a prompt that the unlock was good then all youd have to do is turn off the phone, replace Sprint SIM with the TMO SIM and i'd be good to go. But it never worked, I was in the Sprint store for an hour, even read their guide with them saying it had to be on Sprint then click the UIUC unlock before placing the new sim in. They kept blaming TMO even thought their sim goes in after an unlock. So I wish you better luck than I had and hope you get it going lol.
A small warning here for those who need to send a previously SIM unlocked H932 in for LG repair:
After breaking its glass back, I had to send my TMO V30+ in for repair at LG’s center in Texas. At the same time I asked them to replace the screen under warranty, since there was a small cluster of dead pixels just above the navigation bar. They did all that. Cost $88 (including free shipping) with 11 days turnaround.
They also managed to lose the SIM unlock which I had previously been granted by T-Mobile using their Device Unlock app. Realizing this could be a problem, I had included a letter to LG Repair where I begged them to preserve the SIM unlock. Needless to say, the phone is paid off and all bills were paid (including the extra month TMO auto-charged my credit card and refused to refund).
After receiving it back, my Red Pocket GSMA SIM (AT&T prepaid MVNO) only does 3G, not LTE. The TMO Device Unlock app says the phone is “network locked” and not eligible for unlock.
T-Mobile Customer Service first requested unlock instructions to be emailed to me. After 2 days I received an email saying I had to use the TMO Device Unlock app. Duh. After much experimenting on my own (including with my now inactive TMO SIM card) I went to the T-Mobile store where I bought the phone. They were keen to help, but unable to solve the problem. We did confirm that with an active TMO SIM, everything was fine.
I then called TMO Customer Service again, this time asking for Tier 2. Here they finally escalated the case and requested an unlock from LG and said to expect a solution within 72 hours.
Different from the issue reported by @michy21 in this thread mine is the SAME phone with the same IMEI; it was just wiped by LG repair in a way that lost the SIM unlock. OR it really is a new phone or motherboard and they transferred the IMEI.
I should add that there has been no pushback or reluctance to help from any T-Mobile staff. It’s just that the company has baked everything so hard into the Device Unlock app now, so no human is able to do anything.
The only lesson here is to never buy carrier devices -- as @ChazzMatt has been stressing all along, and as I had been practicing myself in my Nexus days. But unfortunately carrier devices are where the best deals are -- which is the only thing that made it possibly for me to buy this class of phone in the first place.
I'll update this thread with the final outcome. Fingers crossed. I’ll be traveling overseas soon, really hope to have it fixed before.

Worst comes to worst, sell the phone on eBay while at the same time buying one of the mint LS998 V30+ for $320. Immediately convert to carrier unlocked US998, bootloader unlock and root.
In the eBay listing for this phone stress the T-Mobile band 71, blah, blah, blah -- which you don't need on AT&T MNVO, but would interest T-Mobile users.

Thank you, Chazz!
I had a suspicion you might suggest that :laugh:
But yes, that would have to be the outcome if I cannot solve it. I'll probably file an FCC complaint first, which michy21 reported had solved her problem. But again, there is no pushback from anybody, which is a positive.
The only attachment I have to this particular phone is my 2 year warranty, which gives me peace of mind. A phone bought used wouldn't have that (or any warranty).
Thanks again!
Edit: Actually, it's not quite true that I have no other attachment to this H932: If/when T-Mobile rolls out B71 in this area, I'll probably give them another try, as they generally have far better network speeds. AT&T service here is acceptable (and widespread) but doesn't blow me away. We only switched because TMO couldn't reach through our concrete brick walls. Red Pocket supports all four carriers, so I can switch to TMO network on my current plan to take advantage of B71.
So my hope is I won't have to part with this phone. AND that @runningnak3d will release H932 root later this year

That does not make sense at all. Has the device IMEI have changed at all? Was the actual logic board replaced? The answer is likely no. So why would the device be relocked by LG? You are giving them way too much credit.
More proof that the device should have remained unlocked is that you can access the device with your MNVO (ATT), if it was truly locked you would not able to get a signal or make a call under your MNVO at all. Sounds more like user error or a miss configuration of your carrier, or both.
Also you should not be trying to run a T-Mobile Specific device unlock app under a different carrier sim,
and it might just be reporting wrong information. Had this happen to me several times in the past, when the device was actually unlocked. You said yourself, you were able to use the device on (ATT)!

Thank you. I understand where you come from. And no offense taken
The problem IS a SIM lock (or "network lock" as they call it). But not in the same way you're thinking where nothing works with an alien SIM. Both T-Mobile and LG have confirmed that.
Some details I didn't mention in my opening post (I meant to warn people here, not argue the matter):
1) LG warned me before they began repair that the phone would come back SIM locked, even though I'd included a letter asking if they could avoid it. I also talked to T-Mobile before sending it in, who said to just request an unlock code if needed (obviously that person was clueless).
2) I've seen other XDA users report how SIM locked V30s could connect on different networks, but NOT get LTE. That's what I am seeing too. One of my goals with visiting the T-Mobile store was to verify that there wasn't a problem with the phone itself preventing LTE. But once an active TMO SIM was inserted, everything works flawlessly.
3) I thought the same thing about not running the TMO Device Unlock app with the alien SIM inserted, but TMO's wording in the instructions they sent me are: "Before completing the steps below to unlock your device you must be connected to the internet via a cellular network in order to complete the steps", not mentioning it must be on TMO. And I DO have 3G internet with my Red Pocket SIM. Nevertheless, my second goal with visiting the T-Mobile store was so we could try the Device Unlock app with an active TMO SIM. And regardless of which SIM is inserted, the app reports that the phone is currently network locked and not eligible for unlock. When running this app on an unlocked phone, it shows the date of unlock -- even after a factory reset. They are obviously storing the lock/unlock state on the vendor, modem or carrier partitions or some such place. And on my phone it is in a locked state.
4) There is not much room for user configuration error here: The phone has been factory reset 5-6 times while testing this, with the only configuration being a Red Pocket APN. That same SIM and same APN work flawlessly in my Nexus 5 as well as my wife's V30 (also H932). Even if I mis-typed the APN, I wouldn't have done so 5-6 times -- and I would have caught it during one of the many times I verified the APN.
So I have no doubt that there is some form of network lock in place that is causing this. And again, T-Mobile and LG agree and have promised to solve it.
You are right that LG had no reason to replace the mainboard. But they did replace both the screen and the glass cover. I think it is possible that they sent me a refurbished phone with my IMEI transferred -- which would explain both their warning that the phone would come back locked, and why the Device Unlock app gets confused when seeing a blank (still locked) phone, but T-Mobile's IMEI database claims that the device is already unlocked (as I saw on the screen in the store).
So, we'll see if they manage to solve it or I have to sell this phone as suggested by Chazz.
Would paying a 3rd party carrier unlocking do the trick? Or does even that seem out of the question now? Before Frankensteining was a thing I did that so I could use an H931 on T-mo. It was $10 well spent as far as I was concerned.

Thank you for the suggestion. I'd have no objection to that at all, but various reports on here had given me the impression that 3rd parties aren't able to unlock the H932 because TMO locked it down so hard (as is the case with Sprint, but for different technical reasons). I could be wrong about that, so definitely something to try.
Thanks again!
Update: It's been four days since I talked to T-Mobile and they promised to escalate my problem and request that LG provide a solution. They said to expect a response within 72 hours, but I haven't heard back from them.
But yesterday, when I tried popping in my Red Pocket SIM (it's in my Nexus 5 until this is solved) everything suddenly worked: Instant LTE, which stayed all day, even as I drove an hour away across town and worked there for a few hours (using hotspot), went on several errands, and back home all last night. LTE Discovery Log showed how it had switched seamlessly between towers, without ever losing LTE. I was certain they had fixed it, and was much relieved.
Then this morning, it had locked itself again. Phone had been on all night, clearly T-Mobile must have pushed another lock. Or rather: One of the TMO services/apps locked it after pulling TMOs servers. No amount of Network Resets, reboot or toggling Mobile Network settings have worked to get it back. I promised T-Mobile not to make any more attempts with the Device Unlock app as it messes things up for them, but I am sure it it would still say "Ineligible for unlock" even though the IMEI is clear in TMO's database (and listed as already unlocked).
As always, the same SIM gives perfect LTE service in my Nexus 5 and on my wife's V30, with the same APN.
I called T-Mobile Customer Care and was unable to persuade them to transfer me to Tier 2. But they did says to expect a call within a day.
It is almost certain I'll have to go the FCC complaint route. It's sad because T-Mobile is otherwise not a bad company. Probably just a small handful of idiots who got this "bright idea" how to protect TMO phones -- which ends up causing so much trouble for legitimate customers.
@jaysus145: Which Unlock service did you use? The ones I looked at which support T-mobile unlock cost $75-150 -- and they don't seem to guarantee success.

I used celllunlocker.net, it cost me $10 to unlock my AT&T version, and took less then a day to complete.

T-Mobile called me back yesterday and assured me they were still working on it and they would get this phone unlocked and please sit tight another day. They confirmed there was nothing on the phone's IMEI or my old account that should prevent it.
I'll check out unlocking services if it comes down to it.
Thanks again!
Final update on this (and solution):
T-Mobile solved the server side problem with a manager override, so that the Device Unlock app now says "Permanent Unlock approved". But it continued reporting "Unlock Failed" nevertheless. Some say because the phone is already unlocked, personally I think because the servers report the phone as previously unlocked. The app also says "Phone is currently network locked" when first running.
Notably, the connection problem persisted, and T-Mobile (after discussing with LG) said it had to be a bad SIM card or a problem with that SIM ICCID and my phone's ESN. As previously described, I get perfect connection and service using the same SIM in my Nexus 5 and in my wife's V30. T-Mobile said that was all they could do.
I then decided it was time to take the matter in my one hands. After much searching and countless Factory Resets and Network Settings Resets, I managed to get the phone working right with the following steps:
1) Remove Google account to disable Device Reset Protection.
2) Factory Reset from the Service Menu: *#546368#*932# (replace 932 with your model number, though this is likely a T-Mobile only problem). From there SVC Menu - Factory Reset (R&D Only). This takes quite a bit longer than normal Factory Reset.
3) Initial setup with WiFi, no Google account. No APN. Phone shows usual connection slowness.
4) Airplane mode, then WiFi on.
5) T-Mobile Device Unlock app, Permanent Unlock. Got the same "Unlock Failed, but Approved" message.
6) Enter APN.
7) Network Settings Reset (Android Settings - Reset menu). Wait for reset to complete. It may go straight to LTE already here.
8) Power off/on.
After this, everything is back to normal. Instant signal and LTE connection, even after subsequent Factory Reset. It's such a relief :laugh:
Edit: I should add that it is quite possible that not all of these steps are required. Probably the Service Menu Factory Reset was the key to undo what LG had done during the repair. I am merely listing all the steps which I used, and which brought my phone back to life.
Please move it to correct forum if this is not the right one.
I bought Samsung Galaxy Note Plus 10 5G in Oct 2019 from Verizon (all paid). I ported my number from Verizon to AT&T 5 days ago (after 9 months of using it with Verizon). My account is disconnected from Verizon and I have received the port is completed e-mail from them. AT&T has confirmed that the sim is fully activated.
But Guess what, When I put the sim in mobile it says another carrier is not allowed to be used on this phone ! For last 4 days I have wasted more than 10 hours staying in Verizon store and on call with customer care and they have no idea what is going on ! Customer care says the phone is fully unlocked. After 3 days of constant trying one of the representative said you have to reactivate the old account again and then try unlock again from the backend (which I have no control of !) . And, guess what, none of those good people are reactivating the account.
Verizon store guy doesn't help, just says talk to customer care and customer care says its unlocked so they can't do anything.
What should I do ?
About the only things I can suggest are:
If you have flashed firmware that is not the Verizon carrier firmware then flash it back to Verizon carrier firmware.
If you have disabled any carrier applications on the phone please re-enable them.
Make sure they are attempting to unlock the phone while you are within native Verizon coverage
I am not sure if a non-carrier branded firmware exists for the Note 10+ 5G, but non-carrier firmware has caused network unlocking issues before. The second idea is just in case you may have used a package disabler and disabled something necessary for network unlocking the phone. Last one is from past experiences where I wasn't able to complete phone activation because I wasn't within Verizon's native coverage area. The coverage I was in, while not roaming (or extended area) was not actually native Verizon coverage... I would tend to believe this would possibly be the same for network unlocking the phone.
Otherwise get a hold of Verizon and hound them to get it unlocked. Not much else can be done really... If the phone qualifies for being unlocked they should unlock it.
Filed fcc complaint
I have filed FCC complaint. I never changed anything in the mobile (didn't even know firmware flash was a thing until now when I started looking for solutions), used it for general purpose. I am in the same area where I bought it. Verizon store guy tried everything from simple reset to factory reset wiping everything out but nothing worked.
I have also ordered a prepaid Verizon sim. I will put that in and will try to get the phone unlocked.
I will post my results after 2-3 days.
Thanks for the quick reply !

Since I had filed FCC complaint online, Verizon Executive Relations department contacted me and She was able to unlock from her side with the help of 'Technical Management' employee on call.

My son had a T-Mobile branded S20 5G and I moved our service to Verizon. I paid his phone off and got it unlocked. Everything was working fine up until a couple of weeks ago. He did an update (didnt pay attention to what kind of update) and now he cant make or recieved calls or text (keepin mind the phone was working fine before this update). Attempts to call result in a message from Verizon saying that they cant authenticate his phone.
I *****ed at Samsung for a bit since his phone isnt rooted and even though its over a year old if a software update bricked it, I felt like they should have some ownership of the issue. It was a waste of time so now I'm back on the phone waiting for VZW tech support.
I think the issue is that its a TMO branded phone on VZW's network and everyone is pointing the finger at everyone else. My question is 2 fold.
1) has anyone ever experienced this before, and if so what did you do to resolve it and
2) I will attempt to root it and flash a ROm on it before I entertain buuying another phone.....hes got enough other **** hes dealign with financially he doesnt need to add a new phone purchase to his plate.
Any help would be much appreciated because I'm pissed the eff off at this point.
Yes we tried different APN settings...he walked into a VWZ store and they were able to get his data working but not voice or text....seems like something is out of whack with his radios). We also did a full factory reset.....same issue persists
I am not an expert on ROMs but I will give you my two cents. When I was playing with my unlocked phone, I realized that mine updated some CSC binaries as soon as I inserted the SIM. I saw some message for it updating the CSC code from XAA to TMB when I inserted TMO SIM on stock firmware. So my suggestion would be to try downloading VZW stock firmware from samfw.com and installing that.
