Subsidy lock?

I bought a brand new ATRIX HD from Craigslist. The person did not steal the phone because he was kind enough to give me his two numbers, his full name and he even gave me 2 unlock codes to try out,but I couldn't read the numbers correctly so the phone went on subsidy lock. Even AT&T verified that phone is not black listed or not stolen.
I am with T-Mobile. According to AT&T since the phone is still in contract with the person who sold it to me. It is not eligible for unlocking and I paid 250 dollars for this phone.
Has anyone cracked this phone down or can unlock cellular.net help me out?

If it's subsidy locked, it can't be unlocked until either the subsidy runs out or someone pays the early termination fee. SIM unlocking is not possible on these devices via any sort of crack, and I don't believe that an unlock code will work. Your best bet is to contact the person who sold you the device.

I spoke to the person already and when I called him after selling the phone to me. He was actually at the AT&T Store turns out he still has a contract with them so the phone is not eligible to be unlocked until his contract is up and thats 2 freaking years. I bought another Atrix HD unlocked that same night I bought the phone so I am stuck with two Atrix HDs and I posted the locked on Craigslist.
My next question is if someone wanted to buy the phone from me on Craigslist. And they happened to be on AT&T. Will putting their sim card work for it since its on their network?

Yes. Att sim cards will work in it.

What's the process to using this phone on ATT?

Hi I want to buy this phone, unlock it and use it for ATT.
I heard you cannot buy this phone off contract and that you must have a service with them. I hear people are just signing up for the service for one day and then cancel the day after.
Can someone explain how they did it?

Pay full price for phone up front and buy the smallest package. After 40 days cancel the service. Some stores will sell it out right without a plan, but you will have to do some searching and calling. I had to go to 3 different stores before I found one that would sell it out right.

I read LTE and 4G dont work so well when you take it back to ATT. I read somewhere.

I thought the same thing. This is not the case with the Note 4. It was an issue with the Note 3 and previous devices in my experience.

There's been conflicting reports about that.

I bought the phone outright. Paid $30 or so to cellunlocker to get an unlock code. Popped in AT&T sim and off I went. Still need to cancel Tmo service.

When you purchase the phone outright you now it and can unlock it.

I bought my Note 4 outright and purchased the lowest priced package I could. I unlocked it the first day I received it, inserted my sim card from Consumer Cellular and was up and running. However, I read that T-Mobile can and have blacklisted the IMEI of phones that don't comply with their terms of service. Since I didn't read the fine print when I bought the phone and service, I decided it would be prudent to go ahead and meet the 40 service requirement to get an unlock code (although the phone is already unlocked) rather than take a chance and have some T-Mobile manager with a Napoleonic complex blacklist the phone. Then I would be out of $800.00. I asked the customer care representative about blacklisting the phone if I didn't meet the 40 day requirement and she said it was possible. I wasn't willing to take that chance. I will pony up an additional $80.00 + dollars to have peace of mind.

I preordered, got phone Monday the 13th.
I unlocked with cellunlocker.net 4 days later.
Been using it on AT&T since last friday. Called and canceled tmobile same day.
Easy as that.

Right but you make it sound like every T-Mobile store or reseller will sell you a phone outright with absolutely zero commitment of any kind like you walked in to buy a pack of gum or bought a nexus from google play store. There are conflicting reports about zero commitment purchases. The safer bet seems to be walking in with the understanding that you may have to agree to a month-to-month or prepaid contract that you can cancel a day or more later.

The best way i can think to explain it is as follows:
A few people have reported that they were able to buy it outright without service. Though many have been denied that option.
Some have implied that Tmobile then unlocked it.
A moderately safe assumption is that you can buy it with service, unlock it via third party service, and cancel your tmobile service the second u get your unlock code. This comes with the gray area of region locking and having to activate it on tmobile first to remove the region lock pior to unlocking. This can be a lengthy discussion, you might not care about region locking, I'll leave it at that, but read into it. I went this route, activated on tmobile for 4 days, then unlocked and cancelled. I say assumption because people are worried about blacklisting and T.O.S.
The most cautious method would be to wait out your 40 days per Tmobile T.O.S., in addition to the time it takes for them to send your unlock code, pay applicable fees, then cancel.
Hope this clears up the options a bit.

T-Mobile has the IMEI of phone they sell you in their records. I confirmed it when I called them and they read it to me for confirmation purposes. They sold the phone to you and they know everything about it. Guaranteed. If their records show the phone being used on another carrier without it being activated with them or unlocked by them then they can blacklist the IMEI of the phone. That phone will then be an $800.00 paperweight. They have done it before and a quick Google search will prove it. I'm not saying they will since that seems to be an unknown, but they can and the owner of the phone will have no recourse. I sure don't want to wake up one day and find out that my $800.00 phone is dead. I might very well be wrong, but I am not willing to take that chance after paying $800.00 for the phone. I'll pay for the 40 days of service.

I just bought my Note 4 full price from AT&T after calling about 30 stores in my area and finding one store with one black model in stock. I ended up paying less than full price because of some computer error that rung up the phone $749.99 instead of $825.99. They charged me the difference so I only paid $825 outright, after taxes. All in all, I saved almost $50 (difference in tax from $750 to $825). I still feel like it is ridiculous though that the AT&T model is $80 more expensive than TMo. Is it worth buying a TMO Note 4 with their baseball discount ($30 off) and trying to unlock it to use it on AT&T? Sorry for my long comment/question.

Bought mine from swappa in a sealed pack. Opened the phone, went to Cellunlocker.com and within 10 min had my unlock code. Works great on ATT

[Q] Galaxy s6 edge sim unlock problem, please help

So i bought this sgs6 edge device from telus canada.
brought it back home, had the unlock code (also bought from telus and several sim free unlocking sites) and the device just keep poping up the same massage: "network unlock code unsuccessful"
tried every guide on youtube and on any forum i found online, nothing helped.
All the methods, through the dailer, everything.
Can someone please guide me how to sucssesfuly unlock my device?
Many thanks!

Sounds like you got a bad code. You should request a refund and buy one from another vendor. Be careful entering the code too many times. After 10 (I believe) it locks and you can never sim unlock it.

Is the phone paid in full?
The only reason I ask is that I bought an AT&T Nexus 6 shortly after they were released. That's the only Nexus not sim unlocked and my condition on purchase was for the seller to unlock it. We met at an AT&T store, I popped in my Verizon sim and the seller gave me the code. I tried it a few times but the code kept coming back unsuccessful. He called AT&T for the correct code and lady told him she couldn't give it to him because it wasn't paid off (although they had previously given it to him). After some conversation, he eventually gave them his CC # to pay it off. They then provided the exact same code. I hesitantly tried it again and it worked.
I also recently learned that the T-Mobile S6 Edge doesn't take an unlock code at all. It must be unlocked by T-Mobile or it can't be unlocked at all.
Perhaps the carrier is somehow keeping it locked front their end?

So you simply say i have to call them and fully pay it off, so they would relese some sort of lock they have on the device and then i would be able to open it with the exact same code?
If thats true thats might work. I'll try it and update for any changes. Many thanks!

Hey man, my phone is fully paid in. I talked to telus and they said the sim unlock is aprooved in thier computers so what is the problem?

Bought a Used Nexus 6 AT&T Won't SIM Unlock

So I messed up and bought an AT&T Nexus 6 on Swappa. IMEI checked out okay and all looked good. Seller said he'd used it on Verizon and was a nice guy.
Decided a little later to try out T-Mobile service and it turns out it is still carrier locked to AT&T. They (AT&T) have told me several different stories, but the latest one is that the original owner has to call and request the unlock. Well the person I bought it from bought it used ... And he's been trying to, I presume, find the original owner to see about him getting it unlocked.
Anyway, I messed up and I have learned not to trust an IMEI alone. But does anyone have any suggestions? I tried two unlocking services and they each took a week and came back with unable to unlock and gave a refund. AT&T unlock site says they can't locate the IMEI.
Anyone been through this? When I insert a sim it requests a sim unlock code. With my Verizon sim, I can make and receive calls and texts if I dismiss the sim unlock prompt, but no data. I can't even find where to enter APN settings to try that out.
At my wits end.

i think you can just use a sim unlock website idk a trustworthy one though

I would tell the person you bought it from to take it back. If he refuses dispute it through PayPal and they will side with you, have him pay return shipping, and refund your money out of his PayPal account once the delivery is confirmed by the shipping service. I think you have 180 days to file a dispute through PayPal. PayPal is extremely biased for buyers, which works in your favor in this case.
Whether that guy knew or not isn't important. He sold you a phone without disclosing that it was sim locked. Not to mention if you're seeing the error on verizon then so was he (he scammed you). Either way that's his problem to figure out after you get your money back.
Also please leave this information in his feedback on swappa. Those of us who buy and sell every month or more need honest feedback to know who to avoid.

Yup. They were the second. They couldn't do it. So they refunded. The IMEI isn't blacklisted so I really don't know what's up.
And the fact that I can call and text with Verizon, but only data is blocked, is weird. The phone registers on Verizon's network and shows up in My Verizon under my account.

It has to be SIM locked.
T-Mobile SIM won't register on the network at all even though it's an active SIM. The T-Mobile SIM works in my other phones. Verizon SIM registers but no data available, and it still prompts me for a SIM unlock code even though I can make and receive calls and send and receive texts.
Honestly, if there's a work-around out there I'm down to find out. I can't even locate the APN settings on this thing ... Had to go in through a Nova Launcher widget.

Luckily you bought from Swappa. They should hook you up. Then buy new from Playstore for discounted price. If it was cheaper there is a reason. Or find a swappa seller with a good history.

The seller has a good history, and has been communicating with me. I just don't know if he really knew how not unlockable this phone is. AT&T did a number on it, first with the extra software and then with the aggressive carrier lock. I'm not used to carrier locked phones since I'm on Verizon. They don't do that.

You are correct. Swappa will work out fine with a cooperative seller. But if the seller proves to be uncooperative at any point, they have no means to help further. If one opens a dispute on PayPal, it can be cancelled at any time. In a case like this, I'd start with PayPal now.

I believe your phone is SIM unlocked. Before unlocking mine, if I inserted a VZW SIM, I got a popup with something like "unauthorized SIM. Enter unlock code to continue".

I don't follow. If it prompted you before you unlocked it it would have been SIM locked. SIM unlocked devices don't prompt you to enter a network or SIM unlock code.

Correct. I am saying that it appears that your N6 is unlocked.

Nope it appears that mine is SIM locked. Not unlocked because if it was I wouldn't be prompted to enter the code. And it would have data on any active SIM. I'm going to try a refund. If that doesn't work, maybe someone with AT&T will want one. For a great price. Ugh.

Question att denied unlock request

I just purchased a Samsung S21 Ultra AT&T version from samsung.com and paid the full payment. I requested to unlock my phone in att's website but my requested was denied because my service hasn't been active for at least 60 days.I do not have any payment installment and contract with AT&T since I paid the full price when I bought my phone. I tried to call ATT customer service 800-331-0500, but each time I said unlock phone to the phone robot, the call was disconnected and directed my to submit a unlock request online. I am current using Cricket Wireless, and the the sim card works on this ATT locked phone. I want to unlock it because I would like to flash the XAA firmware. Does anyone have experience to handle the unlock process with ATT? Thanks in advance.
Update on 3/16/2021:
I called ATT retention department and talked with 3 reps, but no one was able to solved the issue. Two rep said they were not able to unlocked a phone without 60 days ATT service or let me ask samsung to unlock the phone, and the third one directed me to fill the unlocking form in the https://www.att.com/deviceunlock/ again. This request was denied within one hour, claiming "Your IMEI number & device don't match". This reason is different with my first request. I am very confused with their unlocking system. After 24 hours (this afternoon), I submitted an online unlocking request again. Surprisingly, this request was approved within half an hour. This is a happy ending, but I hate this hassle progress.
Hope my experience can help someone else.

Call them again and ask to talk with the Customer Loyalty Dept aka Retainment Dept.
Escalate the case if needed.
If nice doesn't get it, hound them.
If bought with a Master Card you can file a claim for a refund (you need return the phone first).
Trust me if you're assertive with AT&T you'll get it done. Been there, done that... many times

It is not unusual for a Carrier to have this kind of policy - TMobile has a similar rule - I don't know about Verizon, but I wouldn't be surprised if they did too. Like someone said earlier, if the OP complains long enough, there is a very good chance he will get what he wants.

I had AT&T unlock my S4+ as I was in compliance with the contract.
They are contractually bound by that agreement.
They are only obligated to fullfill the terms of that contract although they may choose to alter it on the OP's behalf.
One point to remember though is that they make most of their profit by providing cell service not the devices.
The OP should carefully check the buy out clause(s) in the contract as well as any state laws that apply ie contact the State Attorney General's office.

I found this thread when I did the research. It analyzed the potential reason why ATT's unlock system is problematic.
