Ok so I was trying to unlock this samsung s 4 mini lte SPH-L520 but it seems like it's the only model of S 4 mini that i can't find an unlock code for, is this phone un-unlockable? and what is the difference between the SPH-L520 and all the other samsun s 4 mini?
Well one rather big difference of the Sprint S4 mini (SPH-L520) versus the international models (GT-I919X) is that it uses CDMA networks rather than GSM. I am not sure if you can use it on GSM networks with a sim card. I do, however, know that the Verizon version (SCH-I435) which is also CDMA can be unlocked and used on GSM networks. I used the app RegionLock Away from the play store (and here on xda) to unlock and it worked with an AT&T sim card.
Sent from my SCH-I435 using xda app-developers app
I hope your help

Friend also want to unlock the samsung galaxy s4 mini sph-l520, tell me if you managed to do so and if the method by region lock app I run away and if you could explain to me hcer to also do so. I hope your answer and thanks for the help in advance
sprint sph-l520 NOT a worldphone
I talked with the Sprint folks.
The Sprint variant has a sim tray that is just for the data sim (UICC card) not a GSM sim. And it is NOT a worldphone.
So even if you put a GSM sim in it, the radio is not looking for GSM towers (only CDMA).
But the Verizon version IS a world phone, which is why "wiisixtyfour" was able to unlock his.
That being said, since Samsung has made several versions that do have this capability, it seems possible that if someone modifies these things it could work:
-Modified sprint radio to receive GSM radio frequencies/signals (maybe copying the Verizon one?)
-Modified PRL to look for GSM towers
-Modified SIM tray communication to recognize not just DATA sims but GSM sims as well
I have no idea how to do any of these. But would love it if someone a lot smarter than me can take a stab at it. :cyclops:

SPH-L520 can run on GSM carrier!
Yes, this is what Sprint told me last summer. But it's incorrect. I have a Sprint S4 mini that works on both Sprint and a TMobile MVNO. Voice, text, data (in refarmed area). Unlocking GSM can be done!

avgtuhm, that's only true if you can explain how it was done and it can be replicated.
What does #0111*NETWORKCODE accomplish?
First off, my apologies if I am in error about GSM functioning on my phone.
I will explain what I've done with my Sprint S4 mini and maybe you/someone can tell what is happening. But this is why I thought GSM was/is working on my phone, until supermaxkato questioned this. (Note: I am not a developer.)
My S4 mini is active with Sprint. If I put a GSM SIM in it, of course it does nothing. Try to make a phone call and I get an automated message that it cannot be completed. But after doing the following, I can make calls, send texts, use mobile data.
I powered on with GSM SIM in phone. Entered #0111*NETWORKCODE for my phone in the dialer and hit call button. After this voice, text, data work. However, phone shows "Invalid SIM" in the notifications and the calls and texts come from my Sprint phone vs. the number associated with my GSM SIM. (I didn't realize this until testing last night.)
So did the code just make it so the SIM tray ignores the GSM SIM and functions on Sprint network? (again.. before entering the codes, no calling/texting/data worked with GSM SIM in the phone)
Same results on 2 activated Galaxy phones. Unsuccessful on non-activated S4 Mini.
I am not tech savvy but if anyone wants me to check something on my phone, I will try to get you the information. (I do not have a rooted/modified phone.)
Again, sorry for my mistaken report of success. In retrospect, I should have known it couldn't be that easy.
(Earlier this year, I WAS told by a developer in Colorado that there has been limited success with Sprint S4 minis being unlocked for GSM both internationally and domestic. And a Sprint rep recently told me that this phone can be unlocked internationally for GSM, although I see that it is not on their list of unlockable phones.)
mobile tower problem
mobile network is disabled in my phone samsung galaxy s4 mini sprint spark meid:99000437598028
how to fix this
Yes I am from nooberia not knowing basic information about sim stuff is the normality for me.
I read places the V note 4 is factory unlocked, even tmobile the other day told me that I can use it in their network just not a tmobile note 4 on verizon. so I tried to put in an active sprint sim and well I figured like on the tmobile note 3 I would get a screen asking for the unlock code. Nooooo. LOL booted up like normal except icon at the notification bar says "unrecognized sim"
anyways to use V. Note 4 on sprint network?
I think the problem is with Sprint because Sprints network is not gsm.
Neither is Verizon
My 2 cents on Verizon sim card versatility on other carriers
First post and first up at bat, so let me too proclaim softly that I too am like a citizen of nooberia and a remote village as well metaphorically , but thanks to internet access I recently read that the FCC mandated that Verizon phones that are 4 g LTE capable have gsm sim card compatibility. The FCC allocates a range of bandwidth frequencies to the various carriers which are made accessible through carrier specific sim cards for a mobile phone. Any further clarification and/or corrections on this matter is always sought and appreciated .
Sought out this forum to discover the benefits of rooting a Galaxy Note 4. from those who know much more than I...
I have a kingdom now?
Hi of the blackview 9500 Pro it's not a complete idiot and I'm not afraid to get into the kernal. But like many I've gotten spoiled to the one click wave of rooting and hoping to find the same for this one. The main reason why I need to do this as the frequency bands on this phone will match 4G LTE for AT&T and already know it works for volte4g Cricket which is AT&T. But with this phone it will not under AT&T SIM card you like anything but 3-g band but the Cricket SIM card will utilize the 4G volte band I'm hoping to find some tools to modify this so I can have 4G LTE or volte on AT&T SIM card. Thank you looking forward to reply
Are you sure the native ATT Sim doesn't work? I have a Blackview 9500 (not pro) and my ATT sim shows 4G VoLTE. My second sim is Google FI and it shows 4G.
Sim
I cant be 100% as I have had the phone for less than a week. I went through every APN attached set up I could find. And to note it is a brand new sim card from the att store. I was going to try and switch sim2 (working cricket 4g Volte sim) with sim card 1 and see if sim2 is still 4g... I was hoping to avoid that due to in the past I had to call separate support lines to activate the IMIE... then depending on result possibly have to rinse and repeat back to back calling 2 different support lines... Ugh!
Could you many post what ur APN settings are many I missed something... Note*I was looking for root because I read that you can open up controls/ mods you wouldn't have otherwise with APN
Thx
I'm looking to spend on Note 10 plus 5G, currently on Verizon but the biggest question that I couldn't find the answer is if in the future, I will have to stay with Verizon forever if I want to use 5G on this phone.
Samsung released different snapdragon models for each carrier, but what if I want to switch to Tmobile or AT&T with this phone? Is there a workaround to make these phones work with different carriers, especially with 5G?
S10 5G is out for many months, but I couldn't find a thread showing portability. Although selling the phone for a discounted price and buying other one that works on different carrier is an option, looking to find if it is practical to use 5G when we switch carrier.
Thank you

once its sim unlicked it will workbwith other carriers.. ive tried it on multiole sims from dif carriers
The lte radios should be the same, the 5g will never work across carriers for now considering theyre taping into different spectrum. Modems and antenna designs are different between the different 5g methodology each carrier adopted.

That is very nice to hear. Does the phone work with other carriers once sim unlocked without changing the phone software? Does 5G work on other carriers too, if the bandwidths match? Thanks

I may not understand much details of these modems, however my understanding is that there are some 5G bands common between carriers.
Verizon holds 76% of total available 28GHz spectrum bands and and 48% 39GHz 5g spectrum bands.
At&T holds 40% of 39GHz bands and Tmobile holds 12% of 28GHz bands. If I'm not mistaken the modem in Note 10 5G model supports 600MHz which is new Tmobile band. So, if Note 10 modem supports those 2 5G bands on verizon, technically it should work on at&t and t-mobile too? Although these may work in different cities as of now
Yes and no, I don't know if it has the right antennas, they matter to match the signal length and the obvious is how locked the radio is.
You forget Verizon are evil about keeping their phones there.
It could be the phone is capable but will never be able because it's a Verizon phone and they nerfed something.

In the past we were able to unlock blocked antenna bands using Qualcomm QPST tool and hope there will be possibilities in the future. It's not that Verizon is evil, it applies to all carriers. There has been court ruled regulations that enabled users to take their device to other networks, but blocking 5G would be inconvenience to users, as we all know 5G is the future. I'm going to grab a Note 10 plus 5G for now

technically they wouldnt be blocking anything if they just dont include the antennae/functionailt.. its then up to the user to research and purchase if it suits their needs.
Follow up:
After Verizon unlocked the phone, surprisingly 5G works with Tmobile without any modification. Of course not all the bands. Haven't had 5G signal so far and suddenly when I'm standing near a 5G antenna in downtown Manhattan, I had full signal
I have the same phone. I was not able to see 5G with TMobile or AT&T. I am also not able to get the Verizon hardware off my phone. ( boot logo, etc.) Any work arounds?
Odd. I have the 5G on VZW thats unlocked. My phone works fine with my TM SIM but does not pickup 5G even though my OnePlus 7T Pro McLaren gets 5G.

nope.
the n976v only has vzw and gcf csc codes on it which both use the vzw sales code n network code.. changing carriers should work but on network as the csc should recognize this and load the correct apns n such but the bootani n vzw stuff is there to stay..

not odd.. its a vzw branded 5g device.. its hit or miss on other 5g networks.. they typically use different bands and frequencies and 5g variants dont contain full csc for other carriers like the non 5g devices
So I'm having an issue, I'm trying to get my phone to work with Total Wireless but for some reason I cannot adjust the APN and they can't send me an update to my sim card. I can get the calls and text to work and it shows 4g but no data due to the incorrect APN. Its all grayed out with no way to add or configure it. The IMEI also says its not compatible with Total Wireless which is weird since all other verizon phones have worked before except this Note 10+ 5g.

Where did you buy this phone? I had the same issue, when I changed the code to GCF from VZW. I had to send the phone back to Samsung, as the local samsung experience store couldn't even understand the problem. GCF is for Samsung diagnostic purposes only and they had to change the motherboard board on the phone in order to fix the issue. If your carrier 5g mmwave band is one of the band used by Verizon, you'll be able to use 5G with this phone. I was able to use 5G in NYC with TMOBILE, but not when I moved to a different state.

I can relate the issue you're facing. I was using this phone with TMobile 5G in NYC, but when I moved to different state, I can't get the 5G reception. In order to understand this further, you need to understand the frequencies supported by TMobile and frequencies owned by Verizon. TMobile shares one of Verizon's mmwave band (only around 25%) and these antennas are limited to only few metro cities. Even if you live in one of those big cities, you need to stand close to the 5G antenna in order to get the 5G signal. I remember that I had to stand within 50ft from the antenna in order to get 5G signal (downtown Manhattan near Meridian Lane and Water st).
So I'm new to this. Ive got a Note10+ 5G from Verizon (SM-N976V). Ported over from Verizon to At&t. Works fine accept its on 4G LTE (no 5G... the Samsung S9+ went over to 5G no issues). I am told if I flash the phone to the unlocked firmware it should get rid of the Verizon "lock" and work. I have tried this as per help form Android Central however having no success flashing... I am not exactly that savvy with this stuff... Please help

You can network unlock it pretty easily even if the phone isn't paid off yet. Download setedit by 4a from the play store:
https://play.google.com/store/apps/details?id=xyz.paphonb.systemuituner
and change the setting "vzw_network_lock" from a 1 to a 0. You'll have to buy the expansion pack from 4a to have a foreground guardian that'll prevent it from going back to a 1.

I purchased a Verizon Galaxy Note 10+ 5g from ebay last year to use for Total Wireless. Well the phone wasnt compatible with Total Wireless at the time and I had to switch to Verizon prepaid. Now the phone is compatible but I cant add APN's to the device because Verizon has greyed out the option. I bought a US Mobile Sim card so I can switch all of our phones over since it is cheaper and is a Verizon MVNO, but I cant get everything to work on my note 10+ 5g. I was able to download an app that let me add APN's and the LTE comes up but now I cant get VoLTE to work. Its turned on but when I make a phone call, it switches to 1x. This is a problem since Verizon is doing away with their CDMA Network. I have spoken to Verizon, US Mobile, and Samsung with no help. My other Note 8 will work just fine when I put the US Mobile Sim card in and my Samsung a71 5g wont work at all and wont let me add APN's even with the app.
I have been doing research and found out about SamKEY and bought some credits to change the CSC from VZW to XAA. I was in the process and it gave a warning about locking the SEC so I decided to do more research before I screwed something up.
The phone is unlocked but for some reason, Verizon phones have these issues with a Verizon MVNO. I can add the TMO sim card from US Mobile and it will allow me to edit the APN's without an issue but I get zero coverage here so I cant use it. So how can I change the CSC to get VoLTE working on a Verizon MVNO? Or can I even change the CSC on this phone? I am so sick of Verizon phones but Im afraid to buy an unlocked phone since It doesnt support all of Verizon's bands.

IDK about unlocking an US device. I prefer unlocked devices.
US unlocked versions of Samsung devices are called "U1". It's part of the model number/name.
E.g. SM-G981U is the US locked Samsung Galaxy S20 5g (like for Verizon), and the SM-G981U1 is the US unlocked version of the same device.

Thanks for the reply. I ended up selling the phone and buying a Google Pixel 4 XL. Saved some money and its unlocked. Ill never buy another Verizon Edition of the phone again.
