Can't use T-Mobile SIM with OnePlus 7 Pro 5g (Sprint) - OnePlus 7 Pro Questions & Answers

Hello, I hope someone here can help me, since I've already tried everything I know.
I bought a OnePlus 7 Pro 5g from ebay (https://www.ebay.com/itm/193541542389?ViewItem=&item=193541542389) because I checked on T-Mobiles website and it says it was carrier compatible I'm also aware that the 5g won't work on T-Mobile. The seller assures me the device is unlocked and when I go into System Updates, it says below UICC Unlock that the device is unlocked. But when I insert my T-Mobile sim card it won't connect to the network. These are the things I tried:
Inserted the T-Mobile sim card but it won't connect to the network.
Tried going into settings/SIM & Network/Network Operators and chose T-Mobile 4g but after a while it says the sim card can't register to the selected network.
Tried T-mobile customer support and they say I need to talk to Sprint.
Talked to Sprint customer support and they said I need a new sim card.
Went to T-Mobile and got a new sim card but still nothing.
Did a factory reset but still did not work.
Wiped data & cache but still not working.
Tried updating PRL, Profile and UICC Unlock under the System Updates Setting of the phone using WIFI internet and I got an error.
I don't know what else to try. I even contacted the seller and he assures me the phone is unlocked and that it should work without a problem. I'm in Puerto Rico and using T-Mobile but I can't get this to work no matter what. Can anyone provide some insight on this or does someone here has any experience using this model (GM1925) with T-Mobile?
*Edit*
Forgot to add. When I insert the SIM card and it tries to connect to the network, after a while I get a notification that's titled Phone Services and it says Phone not allowed for voice. Anyone know what that means?

Have you tried with Force LTE app on Android and selecting the correct mode for Tmobile?
Had a similar issue when using Visible phone on Tmobile. After using the App and selecting the correct Network Mode was able to get everything working

Well my problem was solved. According to an awesome telegram group I found and with the help of an awesome member called Chris Starling, we managed to get the phone working. Turns out that some Sprint phones being sold on ebay are semi-blacklisted and will not work with US carriers. The method to solve the problem involves tampering with the IMEI and I barely understood it, the member Chris basically did everything and got the phone working again. So this thread can be closed.
I suggest that no one buy phones from the same seller I got it from.

Hi Lpedraja2002,
If possible can you please elaborate on your solution? I am faced with this same issue, a locked Sprint SIM from an ebay scam. I am familiar with the concept of rooting and changing the IMEI using a root app, but would love to know some more details.
Cheers

Hi.
I also have the same issue. I got the gm1925 model as present. I'm not living in USA but can't use the network in my country. I try 3 sim from several Carrier but it didn't work.
Can you please tell as how you did it.

There is a MSM tool tutorial for unlocking the bootloader on the locked 5G variant. Normally blowing away the software from recovery would work but if Sprint locked the SIM via the IMEI number than it should be possible to unlock the SIM by changing the IMEI. I will be trying this soon using a IMEI changer root app, or maybe using ADB or something. Will update next week.
Edit: can confirm it is impossible to unlock the sim, even by changing the IMEI. One has to get in contact with Sprint.

Following up on this as I recently purchased a OnePlus 7 Pro 5G and am now stuck with it. Wish I read this thread earlier. Can you pass along your contact Chris Starling if he would be able to help?

If it's who I'm thinking of I may know the guy.

If you guys could please edit your posts to not include first and last names that would be wonderful.
Usernames exist for a reason.
Pm if you need help with a semi-blacklisted device, and also don't discuss IMEI flashing on XDA it's against the rules.

i need a help on sim unlock oneplus 7 pro (Sprint) and oneplus 8 (tmobile or Sprint)

I have a Sprint GM 1925 that is debranded and sim unlocked. Both Verizon and T-Mobile confirm it is unlocked but it shows as not compatible and can't be activated by either carrier. I also get a notification that's titled Phone Services and it says Phone not allowed for voice when inserting a T-Mobil SIM. So any help guys?

To everyone here I might have a possible solution.
I was looking for the answer here and didn't found it, so contacted sprint by chat by this link https://www.sprint.com/en/legal/unlocking-your-sprint-device.html talked through chat and waited for 30 minutes. Then I looked for system/updates and then click the UICC unlock it search out for updates and then unlocked the phone. My phone is a one plus 7 pro gm1925. Just hope this could help someone out here.

Hi all,
Amazon and many online retailers are selling this model GM1925. Please advise whether it’s worth to buy. My friend bought this and using via T-Mobile network with 4g however it’s not working with Xfinity Mobile network sim.

Samsung Galaxy S7 Sim Unlock Code

(mod edit)
If the phone is IMEI blocked, which is likely is if reported lost or stolen, then you won't be able to use it on any network in that country afaik
you can't unlock your phone only by rooting and changing apn.
but you can try to contact the person who sold this phone and ask him to fix this issue, I think it may work

Good rule of thumb I have learned and used is to check google locks before seller leaves, And make them sign a bill of sale Printed name date and address, in most states in the U.S. most of these phones are valued over 500$ which With no profe You are technically in possession of stolen property which if valued over 500$ is a felony charge.
I have had a few close calls in the past but I do not now. It sucks cause you can get burned 2 ways.....
orig owner still prob owed on it figured they could sell it and then claim insurance. seen it done many times over to people.

Unfortunately some people do do this. Its crooked Always get a bill of sale and check for google locks if seller is in hurry, Pass it on as much as you may want a certain device and your getting a deal.
I think people get these phones on contract for no other reason than to sell them, then they either report lost or stolen, or don't pay the contract and it gets IMEI blocked
That, or they are stolen phones

it's very risky to buy a used phone in hurry without making sure that 'history' of this phone was good. I think better to add couple hundreds bucks and buy a new phone directly from carrier

sometimes the difference not only "couple hundreds" and used phone is much cheaper then new one. so better to buy a locked phone and then unlock it using sim network unlock puk code

As a general rule, whenever you will buy another device from a person or third party, check the IMEI both http://imeipro.info/
At least this is one extra filter through which you make sure you buy a phone with a clean IMEI.

is this model DSDA (dual sim dual active) or DSDS (dual sim dual standby) ?

it's DSDS (dual sim dual standby), but you can activate some sort of imitation of "active" mode in settings. if sim1 is busy and someone calling on sim2 (which is offline because the phone has only one baseband) all income calls on sim2 will be redirected on sim1

you should flash t-mobile stock rom, clean cache/dalvik cache and unlock it using Network Unlock app. after that you will be able to flash any custom ROM

im now back to g930t do i need to agree to the device data collection from tmobile pink screen in initial setup process for this to work?. and to clear dalvik cache dont i need to be rooted for that? i thought flashing back to stock does that automatically. thank you for your patience im still learning,( but totally dedicated in this art. ask my wife.) one more question since tmobile has terms for unlock policy one being on network for min of 40 days, does that mean i need to request unlock using a tmo sim inserted or can this be done using wifi? reason i ask is becasue im a att user and another policy for unlock is 2 requests per 90 days. and ive already attempted a temp and perm unlock. both said inelegiable. so im trying to narrow it down to see if i needed to have tmo sim inserted at the time to connect to there remote servers. if so since i didnt at thetime of request im hoping that the 2 unlock requests didnt count. and on the other hand that would be a pain because i dont have a tmo sim. or could this be achieved using wifi.?

Sprint Galaxy s8 sim unlock

Hey there, I want to sim unlock this Gs8 I got from Sprint, Model: Sm-G950U , Software version: G950USQS2BQL1, I received an unlock code but was not able to input the code because it just said sim error contact sprint immediately, Unlocking by sprint isn't a choice as they extorted money out of me, I really want my galaxy s8 to be in service again any Idea where to start? Any help will be much appreciated , I come from a background of good software knowledge so other approaches are good too.
Sprint extorted money out of you?
Extortion is illegal in this country...
Does your phone asks for codes or not?
If it doesn't ask for code you can try the following 3 methods, however, they are not 100% guarantee to work:
Method #1: Go to the dial screen on your phone as if you are going to make a call and press #7465625*638*# Once prompted for code, enter the 8 digit Unlock Code.
Method #2: Go to the dial screen on your phone as if you are going to make a call and press: #7465625*638*UNLOCKCODE#
Method #3: Go to the dial screen on your phone as if you are going to make a call and press: #0111*UNLOCKCODE#
If none of these work, also check if your phone's IMEI is clean and not reported or blacklisted by Sprint.
Sprint phones are usually unlocked one of two ways and neither has anything to do with a code. One is via Sprint with an OTA thing. The other is via root + a 3rd party tool like z3x, Octopus, or something similar.

Need to SIM unlock Sprint galaxy s8 (also fear it may be "black listed" unpaid lease)
I bought the phone from someone and thought it would work but I was trusting instead of smart.. Should've checked it out first. Anyways im negative a couple hundred $$ and I would love if some one would be able to help guide me through unlocking the SIM and if necessary rooting etc. To make it work for my Metro PCS account. In short I need to be able to I assume "SIM unlock" my S8 and hope it'll just be ready to pop my metro SIM into it and it works. Any advice? Will it work if I can just unlock it and use my metro SIM? Or since its an the lease hadnt been fully paid will that be a problem... Ive checked on a couple sites that let you see the IMEI number and if its black listed but it isn't... Please help.

Correct. It IS an advertisement - and not a very good one. He obviously has no knowledge of phones whatsoever if he thinks that Sprint devices use codes
I too have a Sprint phone which I wanted to unlock with the help of information here on the site. Since you won't be able to use unlock codes, and also bcause when I called Sprint they wouldn't help me -told me to contact the seller of the phone to have it unlocked, I was desperate for any unlocking method. Hard to find a working one and didn't want to waste too much time (old Galaxy S5 was already at it's last breath) I made contact with one of the unlockers here on XDA and one was able to unlock it remotely for me. I did pay $15 but with the crappy internet I have and since most unlocking sites are asking $39 for unlocking S8 then I really didn't mind this $15. Took well over a few hours to do since I had to download combination file for my phone which took a while. It's unlocked now thanx to vosi7en here at xda. I do have 1 problem now and that's tethering.....I don't have the option to do any hotspots. Anyone have an idea? I can't root yet cuz I'm on latest Oreo now.

T-Mobile converted to international dual sim single imei question

As the title states, I have a T-Mobile OP 7 pro thats been converted to international. I already have the dual sim tray in it and have used it with a verizon sim in slot one and google fi in slot two. Only verizon required the imei to be attached to the sim. Google fi was pop it in and go.
Both lines worked perfectly with that set up.
I'm about to be using a verizon sim and a red pocket sim on att network in it. Thats going to require me to report the imei to redpocket to activate the sim sim same as verizon.
Will only haveing the one imei reported to both carriers be an issue? and is there a way to retrieve the second imei from the phone?+
I tried searching the forums and couldn't really find an answer.
As long as your 2 sims are on different networks for example one on AT&T and one on T-mobile you should be ok. The only time you might run into an issue is if you are using an mvno's sim that uses the same network as your primary. I'm doing that right now (also on a t-mobile op7 converted to international with dual sim tray) with T-mobile as my 2ndary and soon to be gone sim and Ultra Mobile as my Primary (which also uses t-mobile's network)......T-Mobile has been reported multiple times not to pay attention to this. Other networks may not be so forgiving. To answer your last questions...there IS no second imei to retrieve. The device was intended to be a single sim device so no 2nd one was allocated. The fact it works with the same imei in both is luck more than anything else.

Thanks for the reply, the second part is what I really wasn't sure of if the phone just hid the second IMEI or if it actually didn't have one.
I should be good then. I got the AT&T Redpocket sim and main will be Verizon.

Don't quote me on this, but from days with the 6T, I'm pretty sure it's just not reported in the software correctly but on the network side there are actually two different IMEID.
You should be able to (at least on Verizon) to log in and see the IMEID that is attached to a SIM.
Try the VZW sim in slot 1 and check online for the imei. Log out and switch the sim to slot 2 and check again. Hopefully you should see a different imei. Please let us know what you find out.

@blooddragon78 couple questions for you, as I also have OP7P that I bought from t-mo and switched to international:
- Were you able to use the sim tray that came with the phone? Or did you buy an aftermarket tray? I've heard mixed messages about the tray from t-mo having physical space for 2 sim cards.
- Did you have to unlock your phone to make use of the dual SIM functionality? Or in other words, are you still making device payments to t-mo?

I purchased a dual Sim tray from Amazon. The Sim tray from T-mobile will not fit 2 Sim cards. I'm a t-mobile tech expert so I do know for sure aside from owning one and doing it. For dual Sim to work the device does need to be unlocked as it only has one imei. If you didn't unlock before the conversion you will need to convert back to get the unlock app to be able to unlock.
There were a couple of threads on xda to get unlocked in the system but you still have to run the app. Not sure if they are active still.
If you need some help dm me.
Help with Op 7 Pro Sprint Unlocked version
Hello, I sent you a private message @blooddragon78, but Imma post here as well to see if anyone else can help me out, I'll greatly appreciate it. I came across this thread on being able to convert a T-mobile OP 7 Pro to the international version and enabling dual sim functionality. I was hoping to do the same as well, but I havent made the purchase yet in case it's not doable. Im currently looking at this OP7 Pro (Sprint version) that was factory unlocked and sold on Amazon (it's the OP 7 Pro sold at USD 499 by the Farmug Store) (if will be great if you guys can check and see the product to know what I mean exactly).
My question is what is the difference and meaning between "factory unlock/ phone unlocked" vs "sim unlocked" vs "unlocked bootloader?" I know this phone is unlocked for use on different carriers (and I live in Malaysia even), but how do I convert the phone to the international version so that I can receive updates from OnePlus directly (and not through the carrier)?
And how do I enable the dual sim functionality? Do I need to unlock the bootloader? Am I able to do that myself? Because I got confused as some people say unlocking the sim can only be done by the carrier, but Im not sure what is the difference of that with unlocking the bootloader.
In addition, say if Im able to convert it to the international version and get updates from OnePlus directly, dual sim functionality is enabled and such. Will updating the OS of the phone automatically (not doing it manually) lock the network/ brick the phone?

Hello, I sent you a private message @blooddragon78, but Imma post here as well to see if anyone else can help me out, I'll greatly appreciate it. I came across this thread on being able to convert a T-mobile OP 7 Pro to the international version and enabling dual sim functionality. I was hoping to do the same as well, but I havent made the purchase yet in case it's not doable.

I don't k ow about dual sim.but converting International will allow Ota updates. If it's sim unlocked it should stay. Mine is still sim locked to t-mobile and I'm on internatti fimware

Help, Tmobile carrier lock, "invalid imei"

Hello,.
I bought a phone, 8t plus (tmobile version). when i try to check imei status it says invalid imei... it came with a deactivated sim card.
i tried paying three different unlock site services for the t-mobile unlock app. but they keep returning to me saying that they could not find the imei or its invalid.
I'm in a real pinch here, I love this phone, what are my options? is there some way to force unlock it with a different firmware or something like this? maybe you've got a clue why my imei doesn't show up anywhere?
many thanks
If it's bought from eBay, you're SOL - invalid IMEI is invalid IMEI. You will want to refund it and buy the virgin OnePlus 8T to ensure you don't run into problem.
It will be tough to remove the IMEI from the blacklist, as it's usually death sentence for that ID number, not to mention it's illegal to mess with it.
Especially for this reason, I don't buy used phone anymore unless it won't see network service (usually as a Linux hacking plaything), and I mainly buy new phones ever since to guarantee that I don't run into any problems.

it doesnt give any error, through the tmobile unlock app it says "not eligible" which all unlock sites say that's what you want to get..
THEY say that they cant find the imei anywhere and that maybe I gave them invalid imei, but I'm sure I did not... this happened with more than 1 service site. any clues? i don't want to return it unless absolutely neccessary
Alright, double check your IMEI to ensure you don't make any mistake. There are three ways to check the IMEI, of course; 1. dial *#06#, browse into Settings, and go through "About phone", and 2. touch "Network Status" if the IMEI is not shown or 3. reboot your phone into Fastboot and scroll the UEFI Fastboot bootloader option down to "Show barcodes". It's easy to make mistakes with long numbers like IMEI - had to triple check mine before submitting the application for the bootloader unlock token.

I checked, the imei i gave them was the correct one, I wish that was the problem. how can an imei be invalid (not blocked/blacklisted)?isn't there any way to flash something on the phone to sim ulock it? thanks
even services that CHECK if its blacklisted doesnt work with phones IMEI. what is going on here?! thanks
This phone is not blocked—it’s ready to use on the T-Mobile network.
Device Name Not Available
IMEI: *****************
that's what the unlock service site sent me, they said that is the reply they received..
Alright, if you have Straight Talk or maybe a T-Mobile SIM, test it to make sure it's alive.

You have to have it so long before T-Mo will unlock the device.
Three days minimum if I recall. I had mine unlocked in a week after the purchase, and only have unlocked its UEFI bootloader a few days ago once the LineageOS 18 ROM matured just enough for my liking. Otherwise it's a 40 days wait.

Hey there!
can you PM me a screen shot of your IMEI, please? I really want to look in this. I have a oneplus 8t. Thanks.
​I am outside of the usa at the moment so the T-Mobile SIM card that came with the phone is unable to activate... I'm starting to wonder if that's the only problem
I have found a rather expensive service provider that has full confidence that he can unlock my phone. Will update you further when I have more details.
Is it safe giving my imei to other forum members? can it be used for malicious activity?
Many thanks.
Alrighty, keep us posted.

Then use it on TMobile for minimum 3days then unlock it via tforce on facebook or twitter T-Mobile help. But this requires you to have TMobile service. That's the only way you will unlock that phone those unlocking site aren't connected to get the 8t from T-Mobile unlocked that's mainly for samsung devices trust me I run a repair shop and use the unlocking sites. If you can't get TMobile service then you best bet is to return the device if you can't return your SOL until a simunlock bypass come
I'm not from the USA . Anyone got suggestion how to get it activated ? Thanks
Hey friends!
i've promised to update as it unfolds, day before I was supposed to return phone I got it unlocked by a vendor claiming he is working with T-Mobile directly or something like this, and said he can do it although not cheaply.
That guy had a handful of troubles to deal with me as I put him on a timeline, and not only that, bombarded him with conflicting messages before I decided to actually use his service. he was extremely polite and understanding.
may I recommend an ebay vendor here? if yes I will put a link to his store.
thanks!

Sounds like you purposely bought a phone that was either lost or stolen in the US and was sold to an overseas buyer because the blacklist on devices from US and Canadian carriers does not extend outside of the US and Canada.

Sounds like you're trying to be holier than thou.
I bought it unbeknownst whether it's blacklisted or not. It was brand new and price was great. Where's the problem? Why should I care where it comes from if it works?

It is more of a buyer beware statement about buying cheap devices from other countries.

OnePlus 7 pro T-Mobile unlock

My T-Mobile OnePlus 7 pro is still locked so I haven't been able to use it for calls since I bought it last year.
Can anyone help me with the unlock?
Is anyone working on a possible unlock at the moment?
I need help desperately.

How is your device locked?
Please provide details.( Not trying to be a smartass or jerk)
Just like taking a car to a mechanic and explaining "My car wont work!", the specifics allow the experts to narrow down and isolate the problem

I just know it is network locked to T-Mobile. The person I bought it from told me so. I had no idea it would be so difficult to unlock. If I did, I wouldn't have bought it. I would be glad to provide the specifics but you'll have to guide on what information you need.
Im in the same situation!! only got my imei, and the phone (clean, but i cant unlock it)
OK, AGameOP7 / Kamatron ... By "Locked/Unlocked", are you just referring to being locked to a carrier and required to use a T-Mobile SIM card?
Or, do you mean that you can't unlock the phone or can't unlock the bootloader?
If it is the former (my guess), T-Mobile is required by law to unlock your phone from being used on T-Mobile's network when the contractual commitments for the phone (usually, a one or two year contract) have been met by the original owner.
If you bought these used from friends/family, I would expect that they have paid the phone off by now. The OP7P is more than 2 years old now.
You should be able to just call up T-Mobile, and have them look up the IMEI in their records to see if your OP7P is able to be unlocked at this point, which it certainly should. However, if it isn't and the T-Mob CSR refuses to unlock the phone ... you have one more option available. With T-Mob, you can purchase a pre-paid SIM and have it on the T-Mobile network for a month or two to finish off any contractual commitments T-Mobile still requires. That would cost you money, but it could be a last-ditch solution if you need it.
Same Problem,Still unlock one plus 7 pro
