UICC Unlock - Samsung Galaxy A71 5G Questions & Answers

I have the Sprint variant of the A71 5G. I am currently using it with Mint Mobile which uses the T-Mobile network.
I spent some time on the phone with Sprint to get the phone carrier unlocked and they say they processed and expedited the request. After a week, the phone still says it is locked to the SIM carrier.
When I launch UICC Unlock, (Settings > System Updates > UICC Unlock) I get one of 2 errors, either "SIM unlocking could not be completed. Please try again later. Error: Internal Error (407) or Error (6601)
Do I need to have a Sprint SIM card installed in the phone for this to work? Is there some step I might be missing here?

Hey Port,
What it means when it says "Not registered on network" is that your device is not registered on Fido's network. One way to fix this is to go into your Network settings, and select "FIDO" as your network (which should automatically register your phone to the network).
If that still does not work, it is possible that your SIM card is not active and you will need to go in and get them to either:
a) Activate the SIM card or
b) Replace the SIM card and activate it on your FIDO account.
If then it is still not working, verify that the device is actually unlocked. Restart the phone with the FIDO SIM card in it, and if it asks you or a Network Unlock Code, then you will need to do one of the following:
a) Contact whoever you got the phone from and get them to request an unlock code from their provider.
b) Get an unlock code via one of the various methods available on the internet.
Option B will be your easiest option.
Good luck!

Wrong question.
Question is: how to I get the 'enter sim unlock code' screen.
This screen doesn't exist on Sprint SGS5.

so i couldnt take my gs5 with sprint to tmobile?
I think its the same case as the s4 where the 'SIM' only serves as a card for LTE and nothing else. Also sprint is CDMA and t mobile is gsm so I assume that the phones (hard- and software wise) are going to be a little different.

The S5 has GSM capability just like the S4 and the S3 before it. The S4 *can* be SIM unlocked for GSM carriers. I assume the same is possible for the S5, but who knows whether the same method can be applied.

No according to people about note 3 the imei has to be manually unlocked in sprint system then you can do the uicc unlock from phone ... I had to talk to international customer service to get my note 3 unlocked and you can only unlock one phone per calendar year ... none of the other unlock methods worked with note 3 .. it is said to be encrypted and stored in nv ram. .. the note 3 still has not been unlocked and it's been 6 months

I should have clarified. Officially, yes Sprint will "unlock" any of their devices that support GSM - IF you meet their requirements. But they still employ modem blocks that prohibit domestic connections, so the phone will only work internationally. The S4, m7, and some others can be domestic unlocked via software hackery.

But that still only gives you international access
I am working on a solution for this.
I have experience doing sim unlocking (I found the sim unlock method for the LG Optimus 3D).
I bought one of this phones to try to unlock it.
What I have found so far:
-The uicc unlock is preformed by Sprint OTA (over the air) by sending a network message to the phone to init the unlocking function.
-This message can be sent by generating a fake message and using a software DFS CDMA to comunicate to the device modem and generate the secuence.
-This was done to the Sprint Galaxy S4 but now Samsung implemented a signed encrypted package for the S5.
-By default, domestic networks (Tmobile and ATT) are locked even though sprint unlocks the uicc
-This can be overriden easily once we unlock the uicc
What I need to continue my search:
-a EFS and NVRAM Backup of a phone that had the uicc unlocked
-a App Log for the uicc unlocking state (a phone that is eligible for unlocking by sprint and activate the application log to monitor the unlocking process)
Any help would benefit the entire comunity.

Sounds great. I would suggest posting in the general S5 section, though I believe Sprint requires you to have it active for 90 days before they will unlock
The 90 day thing is a technical rule, but you can get them to do it earlier via the "back office"

I just created a bounty thread for SIM unlock Sprint Galaxy S5(SM-G900P). Support it, if you are interested. That might help things to get little speed up.

SIM Unlock - Your phone is not yet personalized. ???

Purchased a used D850 that was supposedly unlocked. Is there any way to verify other than trying other SIMS (which I don't have)? Picked up a code from an eBay seller and when I enter 2945#*850# each of the 5 menu items returns "Your phone is not yet personalized" with "Dismiss" as the only option.

You need to put a non AT&T sim in it to find out.

I put in a PagePlus (Verizon) SIM and phone booted normally (AICP Lollipop) and there is no service; there wasn't any message about SIM.

Well there is your problem, You can't use the D850 on PagePlus/Verizon... Verizon is CDMA carrier not GSM. The only reason why Verizon uses sim cards is for LTE.
You'd only be able to use a VS985 or a LS985 on page plus.

I am aware of that.
I switched from PagePlus (Verizon) using the VS985 to Cricket (AT&T) using the D850 with the Cricket SIM. The person I bought the D850 from said it was SIM unlocked and I'm trying to verify that; I've purchased an unlock code for the D850, but when I dial the code I mentioned above each of the five options returns the "Your phone is not yet personalized" message with the only option being "Dismiss."
You then told me to insert a non-accepted SIM so I inserted the PagePlus (Verizon) SIM.

Ahh so you where just testing? Well using a Verizon system to test is not a good test. But wait your trying using a Cricket sim? A D850 does not have to he unlocked to work on Cricket, AT&T Go Phone, H20 and other AT&T mvnos. It just works.
If your trying to use a non AT&T/mvno sim then it would need to be unlocked like if you wanted to use T-Mobile.
Also if the phone is locked you CANT unlock it using a custom ROM, you have to flash it back to stock. But if your using it on Cricket the phone doesn't have to be unlocked.

So your using the back to stock guide and going 100% completely back to stock before trying by using the tot method right?
So are you trying to use the Verizon sim to unlock it? If so that might be a problem and you'd need something like a T-Mobile sim

Yep, it had Lollipop when I got it, so I tot'ed back to KK.
The seller of the unlock code's instructions indicate their code will work with the Cricket SIM or an "unapproved" SIM, so I restored stock KK and entered the 2945etc code and received the message that is the title of this thread.
Perhaps the phone is already unlocked, as the person from whom I bought it said it was. I don't know this to be true, so I'm trying to verify before travel.

You can get a T-Mo sim for free. Either go into a T-Mo store, or get one on their site.
I inserted a T-Mobile SIM and dialed 2945#*850# and after selecting each of the five options I recieved the "Your phone is not personalized" message.
Perhaps the phone is already unlocked? The carrier logo at the top left of the screen said T-Mobile, and when I went into Settings/About Phone it said T-Mobile LTE.

Your phone is unlocked. If your phone was locked when you turn it on it will tell you. I'm not sure but that code I don't think has anything to do with unlocking lol. You never enter a code in the dailer. You always just enter your unlock code when you boot your phone.
Your phone is unlocked or you wouldn't be seeing the T-Mobile network.
I'm having a similar situation. I have the 851, and I'm receiving this same message. The phone was locked to T-Mobile, but I want to use it for Metro. Please help.

Call the original carrier of the phone, they should be able to get the unlock code. If not them, call ur carrier.

HTC One A9 Sprint SimLock

I switched carriers and paid off my Sprint bill. I requested my devices be unlocked and they have verified it is unlocked, however if I put my T-Mobile sim in it says Simlock enabled and It will not connect. I tried to go into setting and request UICC Unlock, but it says insert your original sim. I then shut down insert the Sprint Sim back in and when I try UICC Unlock it says The profile update could not be complete. Please try again later. Am I missing something? The last rep at Sprint told me to do a factory reset, which I did and also cleared device cache. Did not help. Same issue. Any help is much appreciated.

Sprint locked mobile in the UK (EU).

I need some help and advise here.
If a latest phone (lg v50) is locked to SPRINT in the USA, will a UK network sim work in it in the UK? If so, what UK network sim will work in a sprint locked phone?
Or will it need to be unlocked first?
If it needs to be unlocked, is it possible to unlock sprint locked phones WITHOUT going to sprint? Inserting another network sim gives the message "Invalid sim" without any way to insert an unlock code.
Any info greatly appreciated.
