[Q] Best way to SIM unlock my SGH-1337 MF3 Phone?

I want to know what the best method is for unlocking my Galaxy S4 SGH-1337 MF3 build Currently running on the airvoice network. I do NOT have an AT&T account but should I still give them a call and ask for an unlock code? or use an unlocking service? also from my understanding there is no sim unlock method for the MF3 build currently.
Thanks in advance!

If you pay full price, give them a call and they might give you the code.

First, unlocking the sim card is not related to the version of your phone.
So if you bought it from At&t with full price, some of them they will tell you to wait 90 days before asking for the unlocking code.
If you bought it from someone, ask the previous owner to call them and to ask for the unlocking code. Otherwise, use google, and try your luck.

are you talking about unlocking the phone to works with other carriers? yes you can on any version.
or unlocking the bootloader so you can use other custom roms? is yes, then you can't. only roots.

I'm talking for other carriers. and I tried the *#0011# method and the other one witht the long string of numbers I cant remember but it never goes to the menu to let me choose [1]UMTS.

free unlock method has been known to screw people's phones up. There are several warnings throughout that thread the mention it.
Just go with the options that I mentioned, or use google, such as "Auction website" they do some kind of these service I guess.

Actually, on the AT&T MDL and MDB firmwares you were able to sim unlock it through service menu:

MF3 blocked this, so the only way you can get your phone sim unlocked with the update is using ebay or cellunlocker but at a price.

Yeah that's what I thought the case was. Oh well, back to trying to trade my At&t S4 for the Verizon version. Swappa is such a drag.

Unlock AT&T S4 to T-mobile

Hello,
I am sorry to ask this again but I have an AT&T S4 that's currently stock and runing 4.4.2 and I was wondering if there is any way to unlock it for T-mobile? I tired following some of the posts on here but they seem to be old and outdated. Does anyone have any other suggestions?'
Thanks!

I haven't heard anything yet..did more digging and it seems like you have to downgrade but then it's not guaranteed that you can unlock it.. I bought an unlock code for $30..still waiting to get it so I'll let you know if it works lol

If you are an AT&T customer or a previous member you can unlock your AT&T phone by going here. It is FREE and i have done it with all my phones so far. They provide you with an unlock code and all you have to do is insert the new non-at&t sim and enter the unlock code.

Since you have the unlock code, it will be almost the same thing. All you do is insert the non-att sim card and it will ask you to enter the unlock code. Enter the code and now you have an unlocked phone.

Anyone can unlock Sprint LG V20 remotly ?

When i pop in my t-mobile sim card, the phone does not recognize it or prompt me for a network code or anything ? anyone know of someone or a service to sim unlock the sprint variant ? Thank you

Bump

I'm also trying to figure this out, as I am not able to even connect to T-Mobiles server to trigger the unlock. All that my unlock app does is just sit there with a spinning wheel and say " connecting to server, please wait " , so if I cannot get passed that than I'm screwed cause it's gotta at least prompt me if I want to unlock permanently or temporary. Darn thing just keeps spinning like I'm blocked from even connecting. Can someone who is rooted check to see if their phone will prompt for an unlock or not? Thanks in advance!

If the T-Mobile unlock app is on the Sprint version (Which I doubt) use this site https://www.unlockbase.com/phone-unlocking-service/tmobile-device-unlock-app-official-unlock/ otherwise you might contact them and find out if they can sim unlock it another way. Or sideload the T-Mobile Unlock app and see if it works that way (I doubt this would work but you never know til you try)

If you are rooted, it can detect it and it will stay on the spinning wheel. Only way I got it to work was to restore to stock no root and it worked (It kept giving me a unlock not available until I bought the unlock service from https://www.unlockbase.com/phone-unlocking-service/tmobile-device-unlock-app-official-unlock/ )

I was thinking that it was because I was rooted , so I guess I will try and restore to an unrooted state and see if that makes a difference.

I found a guy on ebay who supposedly can unlock the Sprint V20 for $50.

Don't bother. All he will do is already what you can do. Root your phone and use the US996 Rom on it(btw try that.)

is the phone paid off in full? no more monthly obligation? if not that's the reason you can't unlock. it's because you don't own the phone sprint does. NO ONE can get a device unlocked from distributor without full payment fulfillment.

It works fine if you have a rom thats unlocked(for some unknown reason.)

Anything on this?!!! Im about to buy a service but when I pop another sim it doesn't prompt the unlock code screen I heard there's a way to manually get there any help?! Dirty Santa does the trick I heard but rooting the v20 is not easy and I heard lots of side effects

Supposedly yes. i never tested it.

yes sprint unlocks it remotely that is what they did with mine, once I called in they had you run the uicc unlock option in updates. it will say uicc unlocked successfully.

I think you ought to have unlocked before going the U-way. Most unlocker I found utilize the Tmobile unlock app to unlock which is only found on the stock Tmobile firmware. I dunno. Anything is possible. I'm also seeking to unlock mine... I'm outside the US. So I guess I have better chance. Wish there was some free way though.. Goes from $20 to $30 on eBay.. Ain't no cheap unlock these days.

Not really but my guess would be you have to use the stupid unlock app that comes on t-mobile phones. Try www.cellunlocker.net , pretty sure they have the method to unlock using the t-mobile app.

Ok I unlocked 3 T-Mobile s7 edge devices thru unlock base and this is what you have to do
You have to flash the T-Mobile firmware back to your phone thru odin.. Take your sd card out and make sure to click nand erase all while flashing T-Mobile firmware .. You can do this before or after you purchase T-Mobile app unlock.. I did it afterwards
Once you have t mobile firmware on phone use the unlock app to unlock.. Then I flashed the U firmware back but I did NOT do nand erase this time.
My phone is on cricket unlocked and working
Remember to nand erase first or you will get a error on the unlock app because flashing other software such as U screws up the unlock app.. So do a nand erase
You do have to use the unlock app but doing it my way here works perfectly!
Works perfectly.. I done 3 T-Mobile s7 's so far

on the top of the unlock to be able to use the phone in the USA (and we're not offering cleaning service)
which means you won't be able to use in usa
but please contact them about it

I just got unclocked from a seller on ebay. Presently $69.5.. Before unlock my imei was blacklisted. But now imei appears to be clean. Is that how they unlock? Clean imei and then place a call to tmobile for unlock? If there's anyone wanting to unlock, go for esn cleaning 1st (about $20) and call tmobile to unlock your phone and see if they'll do it for free.

unlock LG V20 LS997 Available?!

no and there never will be.. its not factory unlockable its bootloader locked. The root method is replacing the locked bootloader with the us996 unlocked one. No other way around it. You can buy a unlocked version if you would prefer but the LS997 is locked and most likely all newer phones will be locked going forward.

So those pages saying they can unlock it for a fee are lying?
The reason i havent done it with the root method is because ive heard its really buggy and unstable. And something about static screen which idk what it is lol

uicc sim unlock isnt unlocking the bootloader.
2 diffrent things. If you own your ls997 and its paid for sprint will unlock for free,
otherwise your asking someone to help you unlock a either stolen device or one that's not legally allowed to be unlocked since you haven't fully paid for the phone. The later is something that's prohibited on XDA
---------- Post added at 05:02 PM ---------- Previous post was at 04:58 PM ----------
The uicc card slot is unlocked with dirty santa as a SIDE EFFECT, was not the intentions of unlocking the device.
The process was targeted at the boot-loader and the ability to have it unlocked to be able to customize the device and change the software.
The UICC unlock is something else, and can't be discussed on here really. If a MOD would like to correct me, i'm pretty sure device unlocking, and anything related to that is a no-go topic. Legally Sprint or any other company for that matter has to provide the unlock for the device once it completes its term or is paid off, other wise there's a reason why it cant be "unlocked" by them, usually theft is the reason, or past due / delinquent acct

Ohhhhhhh i see..
