I've looked around on the forum and elsewhere on the internet and found mixed/conflicting information with respect to getting better than Edge speeds on an AT&T Note 2 on T-Mobile's network. AT&T's Note 2 appears to support the frequencies for T-Mobile's network (e.g., 1700MHz according to http://www.phonearena.com/phones/Samsung-GALAXY-Note-II-AT-T_id7500). I'm guessing that it's not as simple as flashing a new modem. Does anyone know if it is possible to get an AT&T Note 2 running on T-Mobile's network at higher data speeds than Edge? I'm SIM unlocked and rooted, but haven't tried flashing a radio or modem yet.
I've seen some reports suggesting that it won't work, that there is no way to make the AT&T Note 2 work on T-Mobile's HSPA+ network (hardware limitations). I'd like to find out if that's true so I know if I should return my AT&T Note 2 and exchange it for a T-Mobile model. Wish the carriers wouldn't make this stuff so damned complicated.
*Edit* Saw on another forum that somebody suggested changing the APN settings. I might give that a try, but seeing as the AT&T modem is using 1700MHz for a different radio tech (LTE), I'm not sure it would be able to reconfigure it for HSPA+. If someone knows for sure, it'd be much appreciated.
Thanks in advance!
Update: Spoke with a T-Mobile rep at length. The rep stated that the AT&T Note 2 radio *should* be compatible with T-Mobile's 3G/4G services. However, we were unable to get it to work. Perhaps the biggest obstacle is that there is no "Network mode" menu option within Settings->Mobile networks. Thus there appears to be no way to directly set the network operating more (e.g., GSM, HSPA+, LTE...).
Planning to speak with tech support for a while to try to get more info.
And the conclusion to this: Unless one is inclined to flash a new ROM for it (which isn't a bad option), then it doesn't appear that the AT&T Galaxy Note 2 is easily used with full data throughput on T-Mobile's 3G/4G service. It may be as simple as flashing a T-Mobile ROM onto it. I haven't found enough information on the hardware in both versions, but what I've read here on XDA leads me to believe they're identical, in which case ROM flashing should be simple. On the other hand, if there was a difference in the radio, then it should be necessary to adjust for that by flashing the appropriate modem (also available here on XDA).
At the moment, it appears possible, just not trivial. Because I'm currently carrier-agnostic (e.g., T-Mobile, StraightTalk:AT&T/T-Mobile) I will probably just exchange my AT&T version for the T-Mobile version, which has superior software.

Were you able t o find any solution? or did you just get the tmobile version of the note 2? Also, is the t-mobile version superior to the AT&T version? I read somewhere that the tmobile version can not do 4G LTE and is not future proofed. or is it better to unlock the tmobile version and use it on at&t if needed?
There is a hidden menu I have a sprint note 2 and all I have to do is ##3282# and enter my msl then go into others and select hdr or somthing / 1x

Hey I got a question I was thinking about buying a bad ESN at&t note 2 and flashing a T-mo ROM and modem. I was just wondering does the phone have to be sim unlocked by att or will t-mo be able to sim unlock it ? Also would I still have to call customer service and activate the phone or can I just pop in my sim card from my existing contract/phone? Never bought a bad ESPN phone before but am very comfortable with flashing radios and roms and modems etc... just wasn't sure about the unlocking.
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
For those of you that have the Verizon S9/S9+ .. have you flashed the U1 unlocked firmware? Any bugs?
Do any of you still have the grandfathered unlimited data plan? Wondering if I can get the VZW S9, flash unlocked firmware, and have native hotspot work.
I have successfully flashed U1 and Tmobile Firmware on my g960 (verizon version)
So far, I have not noticed "bugs"
From my understanding U1 is what you get from Samsung Directly. With that said, you wouldnt have any incompatibilities as the barebone hardware is the same in the US variants.
One thing that I dont know though is software updates, if they are pulled OTA or if I have to flash every time.
Advanced Calling works as well as Wifi Calling and visual voicemail.
video calling doesnt work unless you flash a carrier firmware
If you have the grandfathered account with verizon, and you flash the U1 firmware. You can wirelessly hotspot or USB tether "natively"
Thank you for the information! Bummer about video calling, I use that more than visual voicemail.
Definitely sounds like this is the way to go.
Hi there,
I have a verizon phone and I am trying to use the hotspot with my unlimited old fashioned plan. I don't want to root. Unfortunately I brought the Verizon s9 not the Samsung S9 unlocked. Is there a way to bypass the company prompt for the feature and turn the hotspot on yet? I tried the one that works for sprint and it did not work for me with Shortcut Master Lite. Any advice would greatly be appreciated?

yeah you can flash your verizon s9 to the U1 firmware. this will remove that message, but not all things are guaranteed. also its not like youd be able to root your s9 as you got the US variant.
While I have a verizon hotspot plan, I tend to use USB tethering more than the Hotspot(wifi) option.
Checking on my dashboard online, shows that Im constantly within my Hotspot Plan.
I also noticed that on USB tethering, data doesn't count against my Wireless Hotspot plan.

Hi Eastsidebiz
Thank you for your reply. I apologize about not understanding all the lingo. When you say flash is that different than root? If you can flash and not loose your warranty or anything. My question is where do I go to have that done? Or is it something I can do myself? Also what will I loose as far as stock features if any? I appreciate any feedback and really truly thank you.

Flashing the firmware is different from rooting
Flashing the firmware is like installing a new OS on the computer.
Rooting is flashed preboot of the OS, and then executed when the OS is up.
Warranty / Knox by flashing an OEM firmware, this should not trip warranty/knox
rooting a US variant, if you can even do it, will trip your knox, thus tripping warranty.
If you have a US variant, come back to this thread 2 years from now, as i dont think developers are able to do so as of yet.
this thread is very informational if you need to flash your U version to U1.
Which s9 do you have again?
I thought I'd update this thread. I bought the VZW S9 and successfully flashed it to the U1 firmware to get rid of the verizon bloatware. Nice side effect is that the hotspot seems to work.

hey just a FYI.
If you flash another carrier firmware on that s9, you maybe stuck there.
personal experience: I can flash from Verizon to U1 and from U1 back to Verizon, (until verizon patches their firmware to lockdown)
on my other s9 (verizon, work phone) I flashed to U1 then flashed to Tmobile, now Im locked to tmobile, until another U1 and or Modded Odin
Thanks for that notice. As of right now I don't see any reason why I'd be inclined to flash anything other than the U1 firmware that I currently have.

Hi There,
So you are saying if I flash to U1 software I can use my hotspot. That is without being prompted by Verizon to add feature. What have you lost in the software from the U1 Flash compared to Verizon Software. If I do it and it voids the warranty so be it. I just want to see what I would lose before I do anything.

Locked to Tmobile can be a couple things, the Phone is actually locked to Tmobile's network (sim locked) ..then theres the Financial/Loss/Stolen/Fraud lock...
ALSO! have you updated your VZW S9's software from verizon in the last 3 months? If so, flashing a U1 may not work, I think the newest Update from VZW has v2 of the bootloader

What is your carrier?
I noticed that TMOBILE is the only one that allows all features to work when it comes to unbranded phones.
On my VZW s9, I flashed the U1 firmware. (using Tmobile) Then Wifi Calling was under the SAMSUNG DIALER option not in CONNECTIONS.
Then on my Unlocked S9, Wifi Calling was under the SAMSUNG DIALER settings (on tmobile), on Verizon SIM, this service is not available.
It looks like VZW/ATT both use their firmware to block outside access. Tmo on the other hand, allows you to fully use your Unbranded phone, but such terrible and outdated technology.
*for those who are getting 20Mbps on Tmobile and happy about that... why??!!?!?*

Unfortunately my phone seemed to have the latest firmware out of the box (February security update) so I might be out of luck then.
My carrier right now is Telcel Mexico (and we don't have fancy features like WiFi calling or VoLTE). I'm planning on switching to T-mobile soon.
What's that of the 20Mbps on Tmobile? Should I pick another carrier?

Wait Feb 2018 may still be V1 bootloader....
So what I noticed with Tmobile (im sure this doesnt apply to everyone) is after 1.2 to 2 years. Your phone line is no longer "new" and data speeds are dropped to least prioritization. Newer plans or line activation obviously gets higher prioritization. Mind you, im not a prepaid user. The only way to fully take advantage of TMOBILE is to switch your device or renew your plan every 2 years, which makes sense and average to some.
on the other hand, I have been having Verizon for the past 4 years, and used 3 different phones then (no line modifications, upgrade.. etc) and my prioritization has been constant. and averaging 70Mbps real time, about 7-9 MB/s (i download torrents on my phone) and its always constant (even if i go over 65GBs a month)... just my 2 cents...

Here's my take: I bought bought an S9 U1 direct from Samsung, did a Smart Switch backup of my damaged S7 to my pc, swapped the SIM and SD cards to the new phone, powered it up, did the Smart Switch restore and was good to go in under an hour, hot spot without prompt etc.
Based on this, if you can flash the U1 firmware you should get the results. The kicker to that is the bootloader version. My wife's s9 from Verizon took the August update and is now on build ... S3ARG9 - the 3 indicating v3 of the bootloader. The latest U! firmware available is S2ARF4 - bootloader v2 and you cannot downgrade the bootloader. BUT if you happen to be on the ARF4 or earlier build then go ahead and flash. Samsungs Voicemail app works with Verizon's VVM (basic), Messenge+ also worked, though I switched to Mood so that I can assign specific notification sounds to certain people.
Att to Verizon.
I bought a in Att s9 g960u phone and I want to use it on Verizon. I got a sim unlock code from a 3rd party so it is sim unlocked but I put in a Verizon sim and it doenlsnt connect to verizon. Is this because of the Att phone uses GSM and Verizon uses cdma? How do I get around this

Phone hardware should be the same. Possibly flash the U1 firmware. Or you may have to enter in carrier APN settings - I've never had to do anything like that but I have heard about it before.
Hi! I'm using the Verizon Variant of the Moto Z2 Force on Red Pocket Mobile right now. I'm using AT&T towers and everything works great except LTE. I can force it into LTE, but my calls won't work. When it's in LTE/WCDMA mode it falls back on H+ everytime. While H+ isn't slow and has been good to me, i'd still like to get LTE. Can I flash the AT&T stock ROM to my variant with success? Or is there another method of getting my phone to lock onto LTE while still having WCDMA/GSM on standby so I may receive calls also?
I previously had a Verizon Samsung Galaxy S8 Plus which had the same issue on RPM, it wouldn't lock onto LTE. To fix this issue I flashed the international ROM with odin and it worked great locking onto LTE instead of H+ after flashing the ROM until it took a tumble down my basement stairs. So that's why I thought it may be possible with my Verizon Z2 Force.
Thank you!
We can not cross-flash between variants without unlocking bootloader. ATT and VRZ are both bootloader locked ones. It seems no one had done it before.
Wow, that bums me out to hear that.
Hey, I too am using the VZW version with ATT service, and I know exactly what you mean! Same problem here.
Will the unlocked S20 Ultra work with Tmobile Wifi calling?
Hi,
Not sure but here's my history:
Bought an unlocked S9Plus from Samsung, had issues with WiFi calling on tmobile, never got it working.
So when S10 Plus came out I bought the Tmobile version from Samsung, everything works great.
So I just ordered the s20Plus from Samsung but the Tmobile version to make sure all is well with WiFi
and Tmobile's 5G systems. After a month or so I call Tmobile and get it unlocked, so no problem there.
Just safer to get all the Tmobile crap on there to be safe, also no issues with voicemail to text app either.

WIFI calling may not work I've been told. I just ordered a S20 + unlocked that I plan to use on Verizon. I would have gotten the carrier specific except I am buying it out right and would only get $300 trade in on my S10+ unless I used Verizon financing.
I refuse to do that so I went with the unlocked and got my $600 trade in. If I have bad problems I can always send it back and get the branded one.
My concern wasn't WIFI calling or VoLTE I had to make sure Mobile hotspot and MMS will work and I have been told they will.
I don't use the other features, so they don't matter to me.
So I have the unlocked S10 I use on TMobile work's beautiful and the s20 should as well I can even use wifi calling like you questioned which I hope carries over as well but I'm assuming it should I'll know in about 4-5 days
yeah every unlocked phone I have used on Tmobile wifi Volte has always worked, that`s why I stick with Tmobile, ATT sucked for unlocked phones....... except for the pixels, anything else wifi calling and VOLTE would`nt work.
As soon as I put my t-mobile sim in my U1 it re-starts and installs wifi calling feature. Just confirming it does work

Wi-Fi calling usually works on the unlocked Samsung phones, it's the in-dialer video calling that doesn't. Also, T-Mobile's implementation of RCS in the messages app doesn't work with the unlocked phones. It's usually very easy to flash the T-Mobile firmware using Odin on the unlocked model. That way you get all the carrier specific features. Make sure to boot your phone on the unlocked firmware (with the TMO SIM inserted) before you flash over to the carrier specific firmware. It's known to cause issues if you don't.

Do you know if the same thing works for Verizon? In other words, can an unlocked Galaxy S20 be flashed with Verizon firmware in order to enjoy any Verizon specific features, but still enjoy being bootloader unlocked and rooted?

You can't be bootloader unlocked and rooted since Samsung does not allow you to unlock the bootloader in the US for any carrier. If you're referring to Exynos phones, you can't flash those with the US (unlocked or carrier) firmware. For US phones, you can only flash the US unlocked to any of the US carrier firmware or the carrier phones to the US unlocked firmware.
You can find the firmware here: https://forum.xda-developers.com/ga...g986u-g986u1-firmware-links-flashing-t4054629

It's a very easy process and it will not "lock" your phone. You can flash back and forth with no issues.
T-Mobile RCS shows users who are on with a blue dot next to the contact name. It is also different than the Google RCS. If you want to use Google RCS, then everyone you message also needs to use Google Messages in order to take advantage of it. It's up to you if you choose to do it, but if you use T-Mobile and your friends and family do too, it might be worth it.
EDIT: Also if your phone is carrier SIM locked, flashing an unlocked firmware will not unlock it for use on other carriers.
