Root then in TWRP terminal or wherever type echo "TMB" > /efs/imei/mps_code.dat then flash the G96XU omc folder in a CSC tar and should be good to go.

@FatalONEM8 Hello thank you for you time i happen to buy the new Note 9 dual sim exynos will this steps work for the note 9 ?

Are you planning on rooting it? If so there is a way to make your phone work full with T-Mobile.

Is there a way to do this to make it work on the bell network in Canada? I don't mind rooting it just been a few years since I've done anything like that so a walkthrough would be awesome

?SIM Unlocked Sprint S6 on T-Moile?

OK Question:
I have been trying to find reliable information on this specific question for quite some time.. I am wondering two things:
How well will a Sprint Samsung S6 work unlocked on T-Mobile? I was comparing Basebands or bands or whatever and it has most of the LTE bands but none of the 3G bands. Does that mean that IF I was in a place where LTE was not available that it wouldn't be able to connect to 3G? How well would this work?
Thanks

Ok Please give me more information. how well will it work? Perfectly all the time?
If you are in the United States, by law the carrier cannot "lock" a phone to be only activated by their own network. You may have to call them to get it unlocked though. They may request for you to pay off the ETF on it, which is usually the remaining balance of the discounted phone on contract.
So really there is no such thing as a locked phone anymore, at least not for now. The hardware on the Samsung S6 should be the same for all carriers, the only difference should be the SIM card.

Carrier Unlock Tab S3 Verizon for TMobile

Hey. Are there any Tutorials of how to GSM Unlock a Galaxy Tab S3 LTE to be able to use a T Mobile SIM Card with a Mobile Internet Data Plan?

Why wouldn't you just buy an international LTE Tab S3? The VZW version is going to have their crap and modifications on it and most likely will be updated 6 months behind an international version if at all. Do you know if the VZW version supports T-Mobile's band 12? The international version doesn't and folks on T-Mobile get 8MB down in those markets that rely on band 12 heavily.
While all of the above is true, VZW devices should be SIM unlocked out of the box due to their block C agreement. The primary band for TMO is band 4 so you should be fine but yes, it is missing band 12 so if you live in a band 12 area, you're possibly giving up some coverage, particularly indoors. I'm in Chicago and since we don't have band 12... Doesn't matter to me.

Does anyone know if they come out of the box unlocked through Verizon? As I also want to use it on my T-Mobile unlimited plane to replace another tablet but buy the tablet through Verizon as it is not offered at T-Mobile.
Postpay Device Unlocking Policy
We do not lock most phones or tablets that are activated with our postpay service, either during or after the term of your service contract or Device Payment Plan installment sales agreement.
We do not lock our 4G LTE devices, and no code is needed to program them for use with another carrier.

In case anyone else was wondering. Found this on Verizons website.
Not to bring up an old post, but the US Cellular S3 is also fully unlocked. I have it running on ATT with just apn modifications

Question about Unlocked s8+ Sprint

Guys, my cousin got me a new brand sprint s8+, unlocked of course and I'm from Tunisia.
However I've got some questions about it:
I'm using Tunisia's carrier mi Sim not Sprint, but I've noticed that 4G is not perfect as it should be, had A7 2017 before and the 4G in the A7 worked perfectly, but in s8+, sometimes I strugle with the 4G and it says on top, "LTE" not 4G like the one in A7, wondering why ? maybe cause I'm not using sprint carrier ?
I wanted to instal a stock firmware of s8+, the international stock one not sprint firmware, is it possible ? cause some applications and some service are from sprint that I'm not using them and useless to me that take up my the RAM memory and even drains battery, so where to get that firmware and is it possible to instal it in my phone ? g955u model
Thanks

Need help with custom ROM on Galaxy S9+ Dual sim

Hello all,
Just bought a Samsung Galaxy S9+ dual sim (SM-G965F/DS) (G965FXXS7GSJ3) international model. Since I inserted my T-Mobile sim card I can only get the 4G signal and no LTE (also tried Verizon sim card and the same result). Speed test on 4G with a few different location (Northwest) and the result from 1.00mbps - 22 mbps max. I online chat with Samsung support and found out that USA don't support dual-sim and that's the reason I don't get the LTE service.
Is there a custom ROM or a way to flash my phone so that I can use the LTE service on my phone?
Thanks

Sorry but whoever told you they don't support DS sounds like BS to me, the carrier only see the phone signal, they don't know if it's coming from a single sim, dual sim or multi sim gateway device.
If you go into.....
settings --> connections --> mobile networks
and make sure both sims are set for LTE
1- 4G/LTE are the same. LTE/4G icon changes depending on ROM and carrier.
2- Samsung agent has no idea. It's a person on a generic building in India contracted by Samsung most probably.
If you own a dual sim s9+ you can get both modems/sims to work on 4G/LTE even at the same time.
If you see 4G you are working on LTE. Then what speed you get it depends on several factors, not just the phone or signal

T865 on T-Mobile

I was wondering if anybody is using the international T865 on T-Mobile, and if so, how is the LTE signal? I know this model doesn't have all of the T-Mobile LTE bands, but I believe it has a couple of the important ones? I ran an international Tab S2 on T-Mobile, and it worked pretty much just fine in Los Angeles. I was kind of curious how this might work now, if the network has changed since then or whatnot, and then how the merger with Sprint might affect it in the near future. Any info is appreciated!

I attempted to flash the international T865 on my unlocked T-Mobile S6 LTE with Odin and a Patched Odin but in each case it failed.

Yeah I don't think that works. Have you tried putting a smartphone sim in your T-Mobile S6? I'm sure the system will recognize it as a tablet and not a phone. That's why I want to order an 865 international model. But then again I guess I might look into how much it costs just to add some tablet data to my plan.

I have a smartphone sim (no difference than an normal sim) and get mobile data which allows me to use the phone when WiFi is not available (I don't want to use my phone as a hotspot). The T-Mobile LTE tablet cannot make phone calls or text but can use the text and call on other devices option on Samsung phones which allows you to use the Tablet using your phone number.
On other samsung devices the US models use the Snapdragon chip while the international model uses the exynos chip which can easily unlock the bootloader and root the phone or tablet. I understand that the S6 LTE tablet is using only the Snapdragon chip worldwide so rooting may be much more difficult. However the international version should have the OEM unlock available so the bootloader can be unlocked. Normally I only get the international versions and root, but if is getting more difficult each year to root the Samsung devices. I bought a used S6 LTE and am happy with my tablet.

So you have a smartphone sim in your T-Mobile Tab S6 LTE, and can get unlimited data? Is it a T-Mobile SIM or another carrier? I tried that some years ago with a different tablet and it didn't work because the system recognized it as a tablet and not a smartphone. That would be cool if it works though, I don't care that much about calling and texting, but unlimited data would be cool.
I like the international models too because they can be used like huge phones lol, but they don't have all of the T-Mobile LTE bands, but I think they have enough that it works okay.
