TMobile phone with AT&T Sims card? Possible? - T-Mobile Samsung Galaxy S6 Edge

Hi guys!
So I have been stuck with my AT&T S5 since it first came out in 2014. Now it's wearing off..... (very slow, crashes a lot). I am a root/flash junkie so the only reason why I want to upgrade to s6 edge now is because it's possible to root! I am planning to upgrade to a S6 edge but using a Tmobile device and unlocking the sims to AT&T carrier (I am using AT&T). I have done my research and the S6 edge for AT&T is too difficult to root/rom customize with 5.1.1 (or not possible at all). With that being said, I am planning to purchase a s6 edge running on 5.1.1 with T-mobile.
Anyone with AT&T service have tried this method and works successfully? Few questions to ask.. how is it any differ from AT&T service? Does it matter? Any changes? Text/call/4G LTE works flawlessly just like a normal AT&T phone?
I'm also planning to unlock the sims by the method that senior member, stifilz, posted in one of the other thread, "Sim Unlock - Intl' and Domestic".

Once it is unlocked, you put an AT&T SIM in and you are good to go. Did it on my T-Mo Nexus 5 and on my wife's T-Mo iPhone 5S.

[Q] Using a T-Mobile Note 2 on AT&T?

Hello,
I have the ability to purchase a T-Mobile Note 2 right now. The problem is my carrier is AT&T. I'm not interested in getting LTE to work only HSPA+, but will that even work? To do it, would I have to unlock it, how would I do that? Also once it is unlocked and working with AT&T, would I flash AT&T Note 2 ROMs or the T-Mobile Note 2?
Thanks,

Man, how many of these TMobile on ATT posts do there have to be? Search before posting!
Yes it works, I get 8Mbps down on good days, worst I have seen is 2 Mbps. You will have to unlock your phone, SEARCH for the free unlock. I've seen it posted here, in the N7100 forums and S3 forums. You should be able to find easily. For roms, stick with the TMobile roms on a TMobile phone.
If you don't have plans on going to TMobile or LTE, I would suggest the N7100 international version. More rom development, faster firmware leaks and releases. I also got better battery life out of my N7100. I kind of wish I would not have traded my N7100 for the TMobile Note2. The TMobile version is easier to hack if you want to put it on an ATT dumb phone plan.

Note 4 Sprint in TMobile

Sorry, the Sprint Note 4 unlocked can run LTE on the TMobile network? Apparently it can be rooted and flash custom roms right? Sorry for obvious questions but Im ready to buy one and need to be sure.
Thanks!!
It can be unlocked, but will only work with 4G, not LTE, check the Note 4 questions tab on the sprint section, there was already a thread started a while back ago. T-Mobile will tell you it won't work though, but there are ways around it.
Sent from my SM-N910T3 using XDA Premium HD app
I was under the impression that you'd actually have to change the modem firmware in order to get a domestic GSM unlock on a Sprint device, if the S5 was any indication. That's where it seems to be locked out.
Since the Note 4 was launched prior to Feb 15, 2015, it's very unlikely Sprint will ever bother with permitting any sort of domestic SIM unlock for it (international is another matter entirely), and that's before we get into the missing LTE bands for full T-Mobile compatibility.
That said, if someone does pull off a working DOMESTIC unlock (T-Mobile, AT&T, MVNOs thereof, etc.), I'd sure like to know about it!
How do you unlock it though?
I know this thread has probably fizzled out or not, but THERE IS a domestic unlock for Sprint Note 4 and all others. It is NOT FREE. However, if one would search and read you will find it. Full data and SMS works perfectly. I have 3 Sprint Note 4's on T-Mobile US.

Verizon Galaxy S6 edge plus w/ T-Mobile sim card

So I am currently in possession of a Verizon branded S6 edge+ which I am planning to use with TMo, as far as the XDA community I've seen this subsection as well as subsections for the different carries ex. TMo S6 edge+, Verizon S6 edge+ etc I was wondering what the difference was, also was wondering which ssection, my guess is the Verizon subsection as the phone's innards are specific to Verizon's version but I'm just asking before I get Into the rooting (rather be safe than sorry)
Also has any one else done this? Is there any discrepancy with the signal or anything else?
Any help would greatly be appreciated, thanks
Verizon and tmobile use different technologies. Tmobile is gsm and verizon is cdma
re: Verizon S^ Edge+ on T Mobile network.

The new Samsung S6 Edge+ and Note 5 Verizon phones can also use sim chips.
Both of those phones have sim chip slots which are the same size as the T mobile and
Note 5's sim chip slots.
All you need to do before you do anything else is to borrow a friends T mobile or AT&T
sim chip for a quick test, then power down your phone, insert the T mobile or AT&T sim
card to make sure it works properly and that's it, you don't need to do anything else.
The Verizon Note 5 and S6 Edge+ do not need to be unlocked for them to work with
the AT&T or T mobile netework and sim chips.
Both the Verizon S6 Edge+ and Note 5 have the capability to use the same mobile
bands and frequencies which T mobile and or AT&T networks use.
It is very true that older Verizon phones did not have sim chip slots and could not
be used with any sim chip, but in the past couple of years but thanks to Samsung
changing the internals of the new phones they now can work with sim chips just fine.
I am sure you know that the Verizon S6 Edge+ or the Verizon Note 5 cannot be
rooted at all even if they are used with a T mobile sim chip on Tmobile/AT&T network.
That means you will not be able to flash any custom roms, kernels or custom recoveries.
The Verizon S6 Edge+ and Note 5 even if used on the Verizon network cannot be rooted
and cannot be flashed with custom roms, custom kernels and recoveries either.
But the phone will work just fine on the Tmobile or AT&T network.
The only advantage I see in getting a T mobile sim card and using
it with your Verizon S6 Edge+ on the T mobile network would be a
savings of at least $25 bucks a month if you only have one line of
service and even more if you have more than one line of service.
Good luck,
Merry Christmas

Unlocked at&t note edge on verizon?

I know they are two diffrent networks with CDMA & GSM. Some phones now cover both. I've read the note 4 was working like this. I'm curious of a couple things.
1. Is it really possible? To go from at&t to verizon with a note wdge.
2. If so, could you flash a verizon rom onto the at&t note edge to have all the verizon stuff?
Well I haven't been looking into this
But from first-hand experience, if you do
Only talk and text messages will work
Anything data-based will not work as the AT&T Note Edge does not have the correct radios to actually get data
You need the CDMA radios to actually use data
and secondly, the AT&T Note Edge (Same with the Note 4) has been bootloader locked since the release of the phone
Meaning the AT&T Note Edge cannot be modified system-wise
We are still trying to get stable temp-root
Not a good sight
And the Verizon Note 4 (Edge as well) have been bootloader unlocked since April of last year
Meaning customization level is higher than the AT&T variant
Now thing is, the Verizon variant is bootloader locked by default
and you need to have a good amount of knowledge of ADB to actually unlock it
and a lot of patience
but the community is there to help you out with any of your questions
As long as the phone has the Samsung eMMC
So why bother with the AT&T variant and just go get the Verizon variant
Bootloader unlocked, and correct radios
Seems like a plus to me
and the Verizon variant has GSM radios so it can work with AT&T and T-Mobile, and yes
It is unlocked by default so you don't need to contact Verizon to unlock the phone

All you need is to first of all
Find the APN settings for your specific carrier
After you do, place the SIM card in and then go to the settings, Mobile Networks, APN settings, and then set it up how it is intended to be

Using Samsung Galaxy S8/S9 in USA (Verizon firmware) with an AT&T MVNO (UNREAL) after 3g shutdown

I have searched for hours without any luck. I have been with an AT&T MVNO (Unreal mobile) for two years. During the 3g shutdown I was unable to use VOLTE on my S8 (VERIZON FIRMWARE). I found out the only way to use my S8 on UNREAL was to have AT&T firmware. I spent countless hours trying to flash ATT firware onto the Verizon S8, but I was unable to do it by flashing, but I found another way. I put a TMOBILE SIM in my S8 and it automatically loaded the TMOBILE firmware. Once the S8 was booted up I was able to run a USSD code (*#272*IMEI#) through the dialer which allowed me to switch to ATT firmware! Problem solved!!!! But a few months later my S8 was lost and I got a S9 (Verizon Firmware). I tried the same method as I used on the S8, but it doesn't work. When I put a T-mobile sim in the S9 it does not automatically change the firmware like the S8 did. From the Verizon dialer on both the S8 and the S9 it will NOT ALLOW USSD codes. Does anyone know if there is a way to run the USSD code (*#272*IMEI#) on the Verizon S9? Does anyone know why the Verizon S9 doesn't automatically change to T-Mobile after inserting a T-Mobile sim? Are there any other sims I can insert in the S9 to change the Verizon firmware in order to run USSD codes? Flashing my S9 is not an option for me because I must be too stupid. Anyhow thanks for your help!!!!
Seem's you+I have similar problem! I have s9 verizon unlocked,but I am with consumer cellular. They went to 4g recently now no call or recieve call! They gave me new sim, still not working! Told me shorter mobile wavelength from tower's! Last update on this phone was 2018? Won't update normal procedure! Wondering since this is U.S.A version if any way to update to 4 g? I'm fine on micro-soldering but when it come's to tech,a little to old I guess!!Lol Any help appreciated!

In my case I had a Verizon unlocked s9 and it turns out Verizon has bloatware that prevents many MVNO's from using VolTE. After tons of research the only solution I found was using patched ODIN to flash unbranded stock firmware in order to chance my model from a U model to a a U1 model. Now the phone works perfectly. Someone should file a lawsuit against Verizon (and ATT) for circumventing federal law on unlocked phones (technically they are unlocked but you can't use them because of their bloatware). It really is a major scam.
