I recently switched to Verizon, my previous phone was a ATT Galaxy s4. Can I unlock the ATT galaxy s4 and have it work on Verizon network?

Unfortunately no. AT&T has a completely locked bootloader from what I understand, and as of now can't be unlocked for use with another carrier.

Sim unlock and bootloader unlock are two entirely different things. You can sim unlock. You might have to buy a sim unlock code.

that's right! lol duh me. :silly: If i remember correctly you will need a sim unlock code...and to get that you have to have been an AT&T customer for I believe 90 days. Then just give them a call and request a code or do it online maybe.

I get my wife a used S4 today that was previously on the Sprint network. We are on ATT and i planned on rooting the phone any ways. What all do i need to change to get rid of the sprint phone number that is on the phone, and what do i need to flash to make it work with the att network?
Don't believe it's possible. ..Sprint is CDMA and dont use SIM cards ATT uses GSM and SIM cards

it has a sim card slot on the phone. They said it was unlocked and would work with all carriers. When i put the sim card in, it says Invalid SIM card

Because its for international SIM cards. Your Sprint S4 WILL NOT WORK on any US carrier other than Sprint.

I can confirm this. I work as a Sprint wireless consultant. A sim unlocked phone from Sprint is not compatible with any domestic carriers.

Its true.. Sprint is the only greedy company that goes out of their way to block gsm domestically within the USA.

I'm sorry to have to disagree with this but I own a blackberry 9630 world phone from sprint and the sim slot works both with at&t as well as tmo. I understand ad long as contract is fulfilled and any etf's are paid Sprint will unlock sim slot and it will work with any carrier, gsm and CDMA alike. Check Sprint forums and speak with cs agents... :good:

Try using an Att/T-Mobile sim on an s4. It will be blocked even if the phone has been unlocked. Previous phones from sprint did not block USA native gsm but as of lately they do.
My good ol htc touch pro was a lucky one to work on USA gsm as of course your old black Berry.
You get it now? Its an accepted fact sprint has been going out of their way to block USA native gsm access on their latest phones. Perhaps some new ones aren't but the s4 is unless a work around is done but it doesn't work for everyone.

This isn't entirely true. I unlocked my Sprint HTC One to run on aio wireless which is on the ATT network. I haven't unlocked my Galaxy S4 but I intend on giving it a shot.
Call sprint and ask for a subsidy unlock code.
You'll need to provide the IMEI
*#06# on the keypad. After they give you the code, try a gsm sim. Hope this helps.

Or buy an unlock code from Amazon or ebay if they wont give it to you ofcourse

thinking of doing the same with my s4 on sprint and going to aio. Been with sprint over a decade and finally over it. In houston and lte sucks.
wow that sucks, because even Verizon who is the greediest of them all will let you use their phone on both AT&T and T-Mobile. I have the AT&T Galaxy S4 and I can use my phone on T Mobile as well.

I tried and tried to unlock my Sprint S4 for domestic SIM but I have failed time and time again. I got it unlocked for International but Sprint has somehow managed to block the S4 from working on a Domestic carrier. I'll let you know if I have any luck.

I think I've read about people unlocking for use on metro pcs which is tmobile. Thanks for heads up though, probably gonna have to buy one when I switch.
I unlocked a Sprint s4 and I am able to make calls with a AT&T micro sim in but cannot get data and texts working. I had to downgrade the baseband to get into hidden menu, but I stopped there. In the hidden menu you have to make some changes but I was scared that if I got it to work on at&t I wouldnt be able to get it back working on Sprint. Everyone does say that Sprint doesnt allow anyone to use other domestic carriers.

Hello,
Is there a way to unlock the factory locked (Verizon, etc..) Galaxy S5, and make it work with any phone network in the world?
Please tell me about all the possible ways. Thank you.
I bought my S5 from a Canadian carrier which had network locked the phone.
All it took to unlock my S5 was a simple unlock code and a sim card from an alternate service provider.
Depending on where you look, you can find unlock codes online for varying prices, I bought my unlock code from cellunlocker.net and it took me roughly 5 hours to receive the code via email from them. All I needed to do afterwards was input the provided unlock code and my phone was instantly network unlocked.

was it cheaper to buy from a carrier then buy a separate unlock code compared to other methods of buying?

What about Sprint? And does that mean it could be used with AT&T or T-Mobile?

Yes sometimes it was cheaper to get unlock code from other source rather than from a carrier. i try several times phoneunlockingshop.ca and find it cheaper then the carrier here in Canada
I just purchased an AT&T S4, I was told it is already unlocked so that I can use on any carrier. Is there a way to verify that without the obvious way, putting in a different carrier SIM?
Also, since the phone is not under contract, can I get the bootloader unlocked by AT&T?

As far as I know, the only way is to test with a different carrier sim.
There is no way to unlock the boot loader.

Hi, I wanted to know whether an unlocked AT&T branded S7E would work on Verizon without flashing the U/V firmware, despite missing band 13. As in, would Verizon approve the IMEI and send in the SIM card because I do not currently have a Verizon SIM and am planning to join their unlimited plan. Thanks
Try it and report back. IM still waiting on my unlock code to come
It will not work with Verizon. Only unlocked phones the except are Google devices and iPhones

Why do you speak of things you don't know about? This is 2017. Most Samsung and iPhones are the same model through every carrier now aside from using carrier specific firmware to lockout certain bands. Right now I am using an att S7 edge flashed with Verizon firmware . But of course you have to sim unlock it first before using on the network. I've been using it for the past week and everything works great. Thank you kindly.

How do you sim unlock the phone first?
I bought an S8 from B&H. Showed up as a tmobile phone so I just flashed the unlocked version onto it. However, I stuck my old sim card from my phone onto it and now its asking for a pin unlock key and a pin. I've tried the ones off verizon and it isn't working at all.
Any ideas?
The phone is sim locked. Most likely going to have to get tmobile to unlock it.

Ah, I get it. I'm going to get it exchanged as I'm pretty sure someone skimmed the unlocked version off and replaced it with the tmobile. The unlocked version should be fine right? Just pop the sim card in?
Thanks
If you get a true unlocked version that should be the case. I bought a US unlocked S8 directly from Samsung and all I did was pop in my Verizon sim. I'm on a prepaid plan so the only extra feature I get is VoLTE. Not sure if postpaid is any different.
