Unlocked and Sim card - Samsung Galaxy S10 Questions & Answers

While I wait on the 8th to get here, I have a question.
I ordered the unlocked version (cause I hate bloat and I'm thinking of switching providers). If I put my current att sim from my s8 in, will that turn the S10 to locked to only att or is it still unlocked to go to any provider?

Should still be unlocked and able to go to any other provider

[Q] Is There a Bootloader-Unlocked Note 3 Available For AT&T Networks?

Verizon has a Developer Edition Note 3 available with an unlocked bootloader. Is there another Note 3 variant available with unlocked bootloader that will work with AT&T (including LTE)?
Please look up the T-Mobile version of the phone. Works 100% with AT&T and is easy to unlock for use on AT&T. It has been posted about here dozens of times, should have all the info.

Unlocked bootloader, not carrier unlocked.
I have both T-Mobile and AT&T. I bought the T-Mobile full price, got a $10.00 SIM Card to activate, then paid 34.00 to have it unlocked. All less than 6 hours. Or you can wait 40 days and have it unlocked for free. I was in a hurry, so I paid. This was so that I can connect to my Gear watch. Now with SafeStrap, I loaded x-note7 and have Bluetooth tethering natively. So now I have a T-Mobile I plan to sell off.
Once again for clarity: I'm looking for a phone with a factory-unlocked BOOTLOADER, not unlocked carrier. Like the Verizon Developer Edition phone, except not for Verizon.

There is a big thread in the general section. A search should have found it.
[Guide] Tmobile N3 on AT&T's Network the Unofficial Developer Edition, CM11/KitKat
OMG... does no-one know the difference between an unlocked carrier and an unlocked BOOTLOADER?

The T-Mobile variant has an unlocked bootloader. It is however carrier locked. So you will have to carrier unlock it in order to use it on an AT&T network. So you will have to get it and pay to get it unlocked from the T-mobile network. It is supposed to have an unlocked bootloader and I am pretty sure that is what everyone is trying to tell you, but not in such a clear way.
From what I understand it is only AT&T that had Samsung lock the bootloader because their plan was/is with using KNOX to create a secure network for business customers and make it so the phones could not be easily compromised.
There is not a developer version or unlocked bootloader AT&T phone. If you want to use a phone that is bootloader unlocked on the AT&T network, buy a TMobile phone.

Question about buying a new Nexus 6

Hi guys. Question, I am about to purchase an "unlocked" New 6. Seller says it is ATT and he will include an unlock code. Doesn't every nexus come unlocked? I thought if I simply factory reset without a sim in it it will just default to an unlocked phone... Any help on this would be appreciated. Reason is I can buy it with the factory stickers and screen cover still on it for $200. I think that's a great deal.
AT&T Nexus 6 is locked. You will need that unlock code.

Once I get that unlock code, will it have any bloat from ATT or be held back by att as far as updates if I stick my tmobile sim card in it?
boot up the first time without your att sim in it, just wifi, then it wont have any att bloat.

If you buy a phone through a carrier its generally not unlocked. Verizon might be different

Yep so when I supported Verizon devices the one thing that always struck me odd was how many went overseas and out of the us. It was because they were sim unlocked from get go.

Verizon phones are always carrier unlocked by default. It has something to do with an agreement they sign with the fcc back in the day. All 4g lte phones have to be unlocked by default for Verizon.

Interesting. Thanks for this info. TIL.
On a slightly similar topic, I have a Verizon Note 8 (that is unlocked, already checked with my t-mobile sim), and I wanted to verify a couple of things. If I were to flash, via odin, the stock non-carrier firmware, will it basically be the same as what you would get from Samsung (i.e. an unlocked note 8)? The main reason I ask, is there are various flashing processes on xda, from unlocked firmware, carrier firmware (which I assume is refereed to as stock in certain xda threads), and carrier switching. Is the carrier switching processes only required when you want to specifically run the carrier firmware? (and thus changing the csc value). If you already have a carrier branded sim unlocked note 8, all one needs to do (to make sure it works as any other unlocked note 8) is to install the Samsung unlocked firmware?
In other words, if I flash the stock unlocked Samsung firmware on my sim unlocked Verizon note 8, will it work on t-mobile with all of the supported bands, etc.? (it is my understanding that carrier features on t-mobile work fine on unlocked samsung phones, such as wifi calling, volte, etc.) Or would I also need to load the userdata file to get those features?
I have searched and read so many threads, and sometimes I feel like I got it all figured out, and then I read threads that seem to confuse the whole situation.... (and most threads seem to be revolving around carrier branded vs an unlocked phone, or sim unlocking a carrier branded phone)

AT&T Note 8 to Verizon

I'm having an issues with a Note I just got. I'm looking to switch it from AT&T to Verizon.
I went through AT&T and got the unlock code, put in the Verizon sim and entered the code. After that I went to switch over the phone on Verizon, but they said that my device was not compatible with the Verizon network.
From what I'm aware of, unlocking the phone would work. Has anyone else had an issue with this? Or do I have to go through trying to flash a Verizon firmware?
Model: SM-N950U
Baseband: N950USQU2BQJA
Android 7.11
As long as it's unlocked the device will work on Verizon, but as the phone originated from AT&T, Verizon recognizes the IMEI as not compatible. If you have another verizon device you can activate that one and do a SIM swap.
You may be able to flash the Verizon firmware over, but Verizon still won't activate it on it's own as the IMEI will remain the same. You may be able to get them to add it to the approved list, but that's up to them.

So if I were to swap over this phone from another one (an S7 that is currently on Verizon to the Note 8), it should work after being unlocked?

Yup. Pop in your activated VZW SIM card. I would also recommend flashing either the VZWfirmware, or the unlocked 950U1 firmware. ,

Could you link me for getting that firmware? I got in contact with Verizon and they said...
I am showing the information as follows: users must have software version of NRD90M.G950USQU2BQK5 or NRD90M.G955USQU2BQK5 before they disconnect their service with the prior carriers (AT&T, T-MO, etc). It also goes on to say that Samsung is working on a workaround so that devices do not have an activation issue but there is no specific date or information that has been resolved.
Would the firmware update fix that?

Check the carrier switching thread for answers. If you don't find answers by searchingfirst, then I would suggest posting your question there.
As far as links for the firmware, check sammobile.com or updato.com.
The current active Verizon sim you have. Place it in the Verizon S7 and give the S7 imei to Verizon to get service. Them once your S7 is fully operable remove sim and put it inside the unlocked note 8.

I have a unlocked AT&T working on Verizon. What I did was a carrier switching and the phone is 100% Verizon , then I call Verizon and they add the imei to Verizon and the phone is fully working..

This is partly true...At&t is GSM based network and Verizon is CDMA. Not shure on which frequency at&t phones can woark on Verizon network, is it only 4G or?!

How long did it take them to add the IMEI? They told me 72 hours and today would be 72. I guess they are taking their sweet time....

Making an ATT Note 9 (unlocked) work on Verizon Wireless

Hi Guys,
I purchased a used Galaxy Note 9 that has the ATT startup and boot animation. I check the IMEI number and it's good, so I went ahead and unlocked the phone through a paid service. When I insert my Verizon sim card, it says that a "Network Locked" sim card has been inserted.
Do I need to load a different firmware to get this to work? I thought the Note 9 supported both GSM and CDMA with the same hardware, but maybe I'm wrong. I haven't posted in here in a while and if this is in the wrong spot, I apologize.
Thanks in advance!

Damn...thank you guys...apparently, the online service said their servers are down and they can't access their database now.
I tried two others so I hope one of them comes up with a successful unlock code. I rechecked the IMEI number and that still comes back good, so I guess it's a waiting game. Thank you for the advice!

Thanks man, just signed up for his service...I will let you know how it pans out. Thank again!
So I was able to get a Note 9 phone I purchased used sim / network unlocked. It was previously on ATT and I'd like to use it on Verizon now. Is it possible to do this? It shows my number, but any other sim information says unknown.
I'm guessing I have to load some kind of Verizon tower info (terminology might be wrong). I thought that stuff is in a CSC file or something. Not sure if I need to flash a whole new ROM, but any guidance would be appreciated.

Once you unlock the phone it will work with Verizon and will configure all the settings as soon as you insert the aim
That's what I thought, but this isn't working. It keeps bringing up the ATT boot animation. I did confirm again that the IMEI is successfully unlocked, but when I login to Verizonwireless on my PC and enter the IMEI it says it's not compatible with Verizon's network.
Is there a database somewhere that has this as a GSM only Note 9. This phone came from an ATT customer...who got the buy one get one free. I sim unlocked it with a third party service.
I'm just wondering if I'm under the false pretense it can handle both GSM and CDMA networks and maybe I'm locked to GSM only...
Any advice is greatly appreciated!

You need to flash it to Verizon firmware . Unlike the note 8 carrier versions , the note 9 doesn't rebrand to what sim card is installed currently.

Hi I successfully flashed Verizon firmware and it still doesn't work.it still has att splash screen and won't connect to Verizon. Please help
Just to make sure that the phone is actually unlocked try T-mobile Sim see if it works.
And if T-mobile sim works then Try N960U1 (XAA) Firmware which is USA unlocked firmware for Unlocked Samsung Note 9 that works with all carriers. so once you insert Verizon sim, it should reboot and set it up for Verizon network.
I did it with T-Mobile Note 8 and was able to use it on Verizon network. Right now I have a Factory unlocked note 9. N960U1 can't really test it because it works with all carriers out of the box.

I just used cellunlocker to unlock my at&t Note 9. Cost me 52$, but none of the free services or the 20$ ones would work. Im using mine on straighttalk with the t-mobile sim.

Did you ever got your AT&T note 9 working on verizon?
I haven't had access to any active Verizon sim cards so I could test them. I just got my note 9 512gbyesterday so I'm gonna give it a go. I'm sure it can happen. Where there's a will there's a way. My only issue is paying 53$ for unlocking. I know there are way cheaper services, I just want to be sure its credible
I have an ATT note 9 unlocked the sim, installed Stock SM-N960U1 USA Unlocked Firmware Odin "N960U1UEU1ARH2" and everything is working like a charm with my Verizon sim card.

I'm not w/VZW,but,I believe if your VZW SIM was activated in another phone,you should be able to drop the SIM Card in (& possibly setting up the APN) & that's it.
However,if you're starting new service w/VZW & the SIM Card hasn't been activated in another phone yet,a call to VZW's customer care is likely in order to get things rollin'.
Again,I'm not w/VZW,just going off memory of what I've read around various sites,so,if your still having issues,contact VZW.
FWIW,it's not the hardware,all US Note 9's are identical on the inside (less storage & RAM options).
Also,some have wrongly stated that flashing firmware will somehow magically SIM Unlock a phone,this is the furthest thing from the truth.
I already had the phone unlocked through a service. I got the code put it in and it said unlock successful. But when you start it up Att logo still shows up and the Verizon Sim does nothing. Other forums say you must upload the unlocked software from the unlocked version of the phone??

There's a few things that could be going on:
1) Even though you checked the IMEI to be clear,that is not a 100% full-proof guarantee of anything,less some proof the phone was paid off in full before you bought it.
Also,the phone might have been reported lost or stolen after you purchased it,but,before you actually took delivery of it (A scam artist coulda sold you the phone).
2) Not knowing which exact unlocking service you purchased,whatever you paid for may not have been what you needed for an actual SIM Unlock.
3) If the phone indeed was/is originally an AT&T Model,I'd guess you'd need to be running that firmware to ensure a proper SIM Unlock,but,don't quote me on that,for now.
I'm guessing you're gonna need to contact AT&T customer care regarding the SIM Status of your phone.................
Once that's resolved/SIM Unlocked,if you want to move to VZW firmware,yes,flash the unlocked (SM-N960U1) firmware 1st,then the VZW firmware afterwards,to ensure full functionality for VVM/Wi-Fi Calling/etc.......
You might be able to somehow get all of that working on unlocked firmware,but,I'm not up on all-things-VZW & the Note 9.
But,1st things 1st,get w/AT&T & see if there's anything going on preventing the phone from being SIM Unlocked before you waste any more money on SIM Unlocking services.
As far as paid services,I've used Masterunlockcode & UnlockBase w/a 100% success rate,there's others out there,some mentioned in this very section/thread..............
