Question about unlocking SIM on a BNIB t-mobile s7 for use on Verizon - T-Mobile Samsung Galaxy S7 Questions & Answers

So like the title says I have a brand new never started/updated t-mobile s7 and I'm looking to use the phone on the Verizon network where I currently have a plan.
I've never unlocked SIMs before so I figured I'd check here first, I don't want to brick the phone obviously..
So my question is how do I go about doing this? I see t-mobile has an app that unblocks the SIM for customers, however I'm not a customer and do not plan on using t-mobile network.
I found some dodgy websites that claim to be able to do it but I'm not sure how I feel about handling over my information to them especially without at least some third party confirmation that the service actually works and is not a scam.
Does anyone have some input on what to do?

Flash the 930U firmware to it. This should allow it to be SIM unlocked.

Try calling tm you just never know they may just give you the unlock codes. I had a phone lock to att once, gave them a ring and they gave me the codes, just be nice.

I used the tmobile unlock app on device. The app checks if you qualify same as a rep would.

So I got the phone unlocked but only to find out the T-Mobile s7 is GSM, Verizon runs on CDMA which is not compatible.
Now that I have it unlocked, would it be possible to flash the Verizon s7 software and have it connect?
I assume I'll need to root the phone in order to do that but will the hardware interact properly with the Verizon software?

CDMA and GSM are two different frequency bands, and use separate hardware. Meaning, they are physically not compatible.

The good news for you is that the S7 sold in the United States all contain the same hardware, the same actual components, so they all physically are capable of handling both GSM and CDMA networks. Also good for you is that now that the phone is unlocked, you can either flash the Verizon firmware or flash the "U" firmware on your device. Normally speaking, this would be really bad advice for any other device, but for the S7 it is possible.
I have the T-Mo S7 flat, and I am running the latest U firmware on AT&T, though I have flashed many and sold them for Verizon.
Don't fret, be happy, and Merry Christmas!

will this allow lte+,in order words can I make a call and still browse the internet on verizon?

Change Verizon edge to T-mobile software

I have T-mobile service, but a friend of mine gave me a Note Edge for Verizon, because my phone died on me. I couldn't turn down a free phone even if it isn't originally for my carrier. Being that the Verizon phone is unlocked it will work on T-mobile's network however it comes with all of their software, and lacks some of the features the T-mobile version would else wise come with. This may be a silly question, but has anyone found a way to root and change maybe the rom or software boot sequence of a verizon phone to flash it to T-mobile software? Is that possible?

Was the article that the S7 will lock to the first Sim inserted true?

http://www.sammobile.com/2016/02/25...-will-carrier-lock-to-the-first-inserted-sim/
I know some t-mobile customers already have devices in hand (or will be getting it within a few days). Has anyone checked if the above article is true? Would be awesome to know for all US who aren't on T-mo or any major carrier (I'm on Cricket, No preorders, and no edge listed so far.)
Would be awesome to preorder the ATT version from a place like target, get those preorder bonuses (target has $100 GC + standard 5% off for target card members, so its probably the cheapest place to get it), and then use it on Cricket.
Note: This is primarily meant for US carriers and devices. not other countries, which has different laws and networks.
Yes I'm also wondering how this will work. When I spoke to sales team at CPW they said it would be completely unlocked but knew nothing about the so called locking feature which may happen to us. Uk
Good question, I'm surprised no one has posted the answer yet considering how many people are getting them.
I'm on cricket as well, and planning to get the tmobile s7 due to the unlocked bootloader (at&t is bootloader locked)... It would be nice not to have to pay some company to remotely Sim unlock it
I would like to know too. Thank you!
I'd also like to know whether the phone will download carrier software specific everytime a different SIM is inserted
Im buying mine from samsung direct so id be annoyed if they have the sim region lock in place. im sure they are selling it unlocked and this sim lock is carrier requested.

Are you in canada? If so there is a sim lock when you put in your sim, but you're given an unlock code with the phone if you get it from a samsung store.
no not canada, well thats good to hear about unlock code, as said im pretty sure the sim lock is only for carrier bought gs7 phones.
Work for a carrier: it will lock upon first sim. If you put in a sim after initial Set up it wipes and reboots. Unlock codes are available like any other phone
CPW never lock their android phones. This feature is for carriers to lock if they want and helps Sammy to sell phones to multiple suppliers using the same SKU code rather than different variants. Anyone buying sim free won't have to worry about this and I'm 99℅ sure shops like cpw won't use this. Buying from an operator however is a different story

Seems like this SIM lock applies to carrier phones only and not Global/International aka Unlocked.
My guess is they do this so Samsung can provide everyone with the same standard S7 model to save hassle on carrier specific phones that are locked from the factory so the carrier can pick up any S7 and provide the sim that then locks to that network.
False.. i have 2 phones.. i just got my S7 and i have an iPhone as well ... just switched the sims and works fine...

I dont understand what you are saying...if you stuck a tmobile sim from your iphone and stuck it in your tmobile s7, its still possibly carrier locked to tmobile.
we want to know if you stick a cricket or at&t in your tmobile s7 first, will it lock to those carriers even though your on tmobile or will it require a remote unlock
I'd be curious to know that if id DOES lock, would a ODIN/reflash of stock reset it?
I would love it buying a AT&T version would work on Verizon or T-Mobile.
All this of course with the phone having access to all bands set on initial carrier SIM card boot up.
Is it possible to just flash a different version's os? Example, could i just flash the t-mo fw onto an att phone?

Oh well yeah in that case I'm not sure because I know my phone should be locked to T-Mobile from the start unless I pay it off in full. I highly doubt if I would have put a non T-Mobile Sim in it first that it would of even got service. You would have to ask someone with an unlocked device if another sim works because most devices from carriers are locked from the start.

Best answer here. I'm not sure what the confusion is here. A phone from T Mobile IS locked to T Mobile unless one removes the carrier lock. Its always been this way (sans int. phones). The carrier unlock app is in the S7 as well and by law all US carriers must provide the unlock if requested by a customer.
So if the OP buys an S7 outright then they can request and will receive the unlock for the phone. Otherwise its business as usual.

AT&T Gear S2 on other carriers possible?

I got an att gear s2 but I don't have att service so I wanted to know if I can use it to connect to let's say T-Mobile since its an esim.
Unfortunately this is why American carriers, at least that's what my knowledge covers, f&#king suck! Out comes this new technology that for the first time will allow people to have the potential to use any carrier with the same hardware, and then carriers like AT&T refuse to unlock them.
Yes, I called AT&T and T-Mobile and AT&T doesn't unlock watches. I hope someone finds a way to somehow port the T-Mobile software over to the AT&T hardware.
The esim should be universal right? Like it should work for any carriers. If so wouldn't it work if we pay for an unlock code? Even tho we wouldn't be inserting another sim, the imei would be released to be used by other carriers. Does it make sense at all? Lol
My n6 was like that. It couldn't be used by other carrier until I unlocked it and its imei was released from att to be used by others.

The problem I noticed is the fact that there are custom settings for AT&T and so even if you unlocked it, I think you would need to still flash the appropriate software. I'm just guessing though.
It's really frustrating that I've got the first big consumer device using an eSIM and I can't take advantage of it's most basic and essential feature.
Any updates on this? The AT&T watch is like half the price as T-mo and I'm interested in using AT&T watch on T-mobile if possible
Any updates? I just switched mobile carriers from ATT to TMobile and would like to use my watch on their network
I have the S2 Classic SM-R735AZKAATT (for AT&T obviously) but I'd like to have it set up with T-Mobile.
Can I take this into T-Mobile and set up service? If so, anyone know how much?

Works with all carriers out of box?

I was recently informed by a mobile carrier rep that all models of the S8 are already unlocked and I have been reading around that it supports both GSM and CDMA on a single device. I am using AT&T (a GSM carrier) but their service around my location in near no existent and I am trying to switch over to Verizon or US Cellular which are CDMA carrier. I'm looking for some confirmation on this and the steps i would need to take to switch providers and keep the same phone. I have. I know that the United States models can be flashed to a different carriers official software but would this be necessary?
They are all the same hardware and all support the same radio bands. Depending on your carrier and which firmware you're running, some features may or may not work on all carriers. I'm not sure about your AT&T version, but the T-Mobile versions come carrier locked. They must be paid off and activated on T-Mo for 40 days before they will unlock it. I believe Sprint is also carrier locked. From what I understand Verizon is unlocked out of the box, as have all VZW LTE devices been for a few years now. AT&T is the one carrier I'm unsure of. Easiest way to find out is to put a different carriers SIM card in and see if it works. If it is carrier locked, AT&T will unlock it for free as long as it is paid off. Just request it through the AT&T website.
Once you switch to Verizon, I HIGHLY recommend flashing either the XAA unlocked firmware, which will detect your SIM automatically and optimize it for VZW. It will be bloatfree, but may be missing VOLTE, WiFi Calling, etc. If you want all the VZW features, flash the VZW Carrier firmware, and be ready for the VZW bloat as well.

Thank you I went ahead and I am using an unlock service and I will be switching to some sort of carrier and flashing to that carrier's firmware.
I have a Verizon S8+ and popped in my tmobile sim and it works perfectly. I made no apn changes. I looked in the apn settings and all the settings for various vendors were already in there.

If I read correctly, he's going the other way, from ATT to VZW, so I don't think all the features will work without the VZW firmware.
i've flashed the phone over to the unlocked fw and unlocked carrier following the Snap+ Flashing Guide on these forums so now i'm waiting for my carrier unlock to be completely free. Will provide and update once i recieve my code and use it.

Please Help. How do I activate, and unlocked tmobile Galaxy S8+ on Verizon.

So I just received my unlocked galaxy s8+ G955U from swappa. I was hoping it would be as easy as putting in my previous nano sim card from my Nexus 6p and activating. It isn't. The branding is t-mobile. Showing t-mobile screen when I turn it on. I tried activating from myverizon , but when I enter the imei it says: "The phone associated with the Device ID you entered is not compatible with the Verizon Wireless network. Try a Different Device"
I purchased an unlocked phone hoping to avoid most if not all of the verizon bloatware. But, I need to be able to make phone calls and tie it to my Verizon account.
Any help, or suggestions would be greatly appreciated.

clearly you got the Tmobile s8+ model. Even if its unlocked it only works with Gsm networks. Verizon is CDMA not gsm. Return for a refund and buy a no-career unlocked phone. Good luck
This is the model you need https://www.bestbuy.com/site/samsung-galaxy-s8-64gb-unlocked-midnight-black/5803742.p?skuId=5803742
I think you're right. This sucks. But, it's good to know. I've been on the phone with customer service for 40 minutes trying to get it activated and still no luck.

What I don't understand is that the customer service representative says it's activated on her end. I just can't make or receive calls. No lte or 3g shown.

That is 100% absolutely false and incorrect. All the US S8+ models have the SAME EXACT hardware. Only the firmware is different.

OP, are you SURE it's network Unlocked? The T-Mo branded S8 shipped network locked. If it's network Unlocked, it WILL work on Verizon, but it will still have the T-Mo bootup screen and apps. That's the firmware.
If you want no bloatware, check out the threads for flashing the Unlocked Firmware.
After exhausting all my options I took my friends advice, and called t-mobile. Turns out the phone is still locked. So it's either the seller unlocks it, or refund.

Maybe you can answer this question. If the phone is still locked. Can I flash firmware to unlock it, and activate it on Verizon. (I don't even care about bloatware anymore. I just want to have a working phone)

No, you can't unlock it just by flashing the unlocked firmware. T-Mobile will have to unlock it.
Read one of the threads a out flashing unlocked firmware, it will answer many of your questions, including the ones you have asked in this thread.
