AT&T wifi calling onTmobile Note 5?

Just seeing if this is possible. I'm on AT&T and had the Note 3 and 4 previously. There is no way I'm getting a Note 5 which can't be rooted, so I'm thinking of getting the Tmobile one. My only issue is that I need WiFi calling at home, where I get crappy reception. AT&T WiFi calling has been a lifesaver.
So, any possibility of getting AT&T WiFi calling on a tmobile Note 5? I don't mind rooting and changing rom, although I have a feeling the issue is with the lack of hardware bands.

Due to the hardware differences in the att and
the tmobile phones tmobile's wifi calling will not work on an att phone even if the att phone is unlocked and rooted.
Good luck,

AT&T currently only supports WiFi Calling on the iPhone 6/6+/6S/6S+.
The software installed on our phones is configured to work with T-Mobile's implementation of WFC, and would most likely not work even when AT&T brings WFC to Android.

OnePlus One fully stock - T-Mobile - no signal/carrier connection 52% of the time

My OnePlus One is on latest cyanogen 12.1, completely stock and unrooted. I am noticing high battery drain on cell stand by (42%)
and of that 52% of the time there is no connection to carrier.
Is there a fix for this issue? My wife's Note Edge (SM-N915G on stock KitKat) has no signal issues with T-Mobile. but my OnePlus One show no connection most of the time. Is this a CM12.1 issue or is this a known issue with OPO and T-Mobile combination?
Appreciate the help.
Which baseband?
This could just be because of where you're located. The OPO only supports one of T-Mobile's LTE bands, band 4, while the Galaxy Note Edge supports all three, including band 12, which has much greater range and building penetration.
All of the recent T-Mobile commercials touting improved coverage area and better building penetration are based off of using band 12 on their newer devices which support VOLTE (voice over LTE). All of their new towers incorporate this band in areas that previously had little or no coverage (especially rural and suburban).
If you're in an outlying area with poor band 4 coverage your handset will be constantly trying to lock in on the weak signal and shifting from 3G, 4G, and LTE. Doing this also greatly reduces data transmission speed and reduces battery life.
If you're in an urban area with strong signal acquisition, then forget what I just said, you have another issue.
Hope this helps.
i used OPO on tmobile and it worked fine, depends on many factors including location, time of day and of course the bands used by the device.

I see from your profile that you reside in the UK. The OP doesn't list his, so I'm operating under the assumption that he's here in the states. My observations and comments in the post above yours, are strictly based on what I know about this device and with T-Mobile USA, as I'm unfamiliar with its operations in other countries.

Apologies, should have included location detail. This OPO is in Austin, tx so its metro area.
Baseband: DI.3.0c6-00241-m8974aaaaanazm-1
Cynogen version: 12.1.1-YOG7DAS2K1
Kernel version: 3.4.67-cyanogenmod-g9220ae3
Build: LMY48Y
Will I get better luck on AT&T with OPO?

You might, but I can't say for sure. The OPO supports 2 of the 3 bands AT&T utilizes, band 4 (like T-Mobile) and band 17. So you have more of a chance. Bear in mind, that AT&T is considerably more expensive than T-Mobile and that they have roaming agreements with each other, where if you can't get any signal for telephony you'll roam off the other's network.
Generally speaking AT&T has more coverage, because it's an older more mature company with a more established infrastructure. T-Mobile is more of an upstart, but is rapidly expanding with a newer technology. Like I said in the previous post, explaining why your wife's Note got so much better reception, newer T-Mobile devices which support all 3 LTE bands (2,4, & 12) get better reception and probably twice the coverage than what is possible with the OPO.
I hope this helps explains things.

yes i do reside in the UK but bought my OPO in the US when i lived there back in 2013 and used it on Tmob. according to the website it works in the UK on Three and EE(tmobile/ orange). i use it on three and get 4g and 3g with no probs. i do like the tmobile usa plan of $40 unlimited all
Since stock 12.1 update, I've noticed mobile network keeps dropping and in return draining the battery quickly.
Thinking it's the update, I've installed custom 12.1 ROM, but the problem persisted.
With further searching, I've found fix here.

Goto APN settings, take note of current APN's.
Reset to defaults.
Copy previous APN values to currently selected APN.
Save then reboot phone.
If above doesn't work, try here.

Scroll down to LTE issues and try the method described. Just note that it suggest deleting other APN, but I recommend against it because it can interfere with roaming.

Thanks, so I am not the only one experiencing network connectivity issues. I do suspect this software related to some extent. Will try the fix and report back.

All phones can now get WiFi calling. Just download digits and sync it. Download it on your main driver and sync it. You can use the DIGITS to call using WiFi from any device using your number.

Using Verizon note 5 on T-Mobile

Sorry if this has been posted before....but is it possible to flash a T-mobile ROM on a Verizon note 5?
I left big red for T-Mobile and bought a unlocked Note 5 that was originally on Verizon.
It works fine with T-Mobile and I am overall happy with the network.
However I travel a lot and would like the option of WIFI calling and also to be able to use the free in air txting on GOGo inflight.
In order to do that it seems I need the T-mobile firmware? Or is this something I can flash?
As the phone is now I have no option to turn on WIFI calling in any of the the settings.
Thanks!
Nope. If you try. You will soft brick it. Only way to recover is Odin back to stock TMO firmware. I attempted with and s4 and s6 from Verizon. I eventually caved and ponies dup for a TMO note 5. The lack of volte alone killed me.
I have a N920V as well and am now using t mobile with great Lte speeds. You 1)dl BK Package Disabler app for Samsung, 2)give it admin permission and disable all Verizon packages (except Mobile Hotspot And Tethering to keep that function), 3)input APN settings for t mobile manually, then reboot. I am unrooted and have great network functionality that rivals Verizons so called superior service.
For in flight free texting there is no need for TM firmware. I have international Note 4 (N910F) with generic rom for TM plan. GoGo works fine during my frequent Delta flights.
I have s7 verizon and have used many verizon galaxy on t-mobile. Wi-Fi calling cant be added. I am able to use the internet intermittently whilst talking but on 3g. On some verizon phones it was nothing while talking.
I have the nexus 6 on Verizon. I really would like to have the note 5. Will the T-Mobile note 5 work on Verizon?

Phone upgrade (g925a to n920p) on Mint Sim (T-Mobile)

Alright... I'm so excited for my 2nd note to come. This is also my 2nd sprint but who cares right? My last note was the Note 4 from at&t and i kinda miss it. But the battery kept overheating and I couldn't flash a rom on the phone. But I know I can if I have a sprint or a tmobile galaxy. Lol I seen YouTube and XDA.. So What's the Best Rom for this note?
I need everything for this thing.( Recovery,Rom...(S8/Note 8 port), everything). I'm using my s6 edge on tmobile and the signal is really low. I mean I still get good 4g lte signal but around 1 to 3 bars. Especially when I'm on the phone with somebody. Wifi calling is included. Hotspot is included. Almost everything works except binge on and visual voicemail. I can get the phone unlocked it's been paid in full.. I just need this thing to run like it's successor (note fe or note 8). it be cool to have the sprint 4g lte icons and the sprint boot up screen and make it feel more authentic with Better speeds and everything and I think that's what sprint has one up on. But I love tmobile so thats why I want this to run as a sprint phone using tmobile. Especially with extended range? I need help and input.
I'm not sure n920p is going to work well for you from a WiFi calling standpoint. Sprint WiFi calling isn't compatible with TMobile's system so the ROM will have to be tailored to work. I had a similar issue with Mint Sim with my Sprint Note 5.

Note 10+ - Horrible signal strength

I received the Blue Note10+ from the Samsung preorder. (SM-N975U1). I'm using it on T-Mobile.
I'm having serious signal strength issues. My Note 8 is at 3 bars while the Note10+ has 0 or 1 bar while indoors. I usually have full 4 bars with the Note8 when I walk outside, but I rarely hit 3 bars with the Note 10+ wherever I'm at. I've never hit the full 4 bars yet with the Note 10+.
Is anyone having this issue? Any suggestions for a solution?
Bars alone don't tell the whole picture as each phone is calibrated differently. The only way to know for sure is running speed tests and comparing actual signal strength numbers in the settings.

Get the actual signal strength on each phone to compare...I have a TMO version of the S10+ and unlocked versions of the Note, the 10+ and a 9... the db strength measures the same on all phones, yet the TMO version shows additional bars... for example, at 99db to 104db, the tmo shows 3-4 bars, the unlocked 2...
Go to About phone, Status, sim card status to get the actual signal strength...
Same. Pixel 3 works, Note 10 has zero bars and doesn't work. I assume it's not connecting to TMobile bands
I'm on Sprint, got the Note 10+ around 9:30 yesterday. No issues whatsoever.
Can you tell us the dbm compared to the pixel? I'm really curious if I should just flash the tmo firmware before I even bother to load it.

You might need to update the PRL? Assuming it's a new phone. Have you contacted TMO?
EDIT: Seems like TMO is having issues.

I am home now. Dbm here is the same and everything works. I was in the area that had signal problems and Pixel was probably using band 12 whereas Note just lost signal for good

Did you check for software update when you got your phone? When I received my unlocked Note 10 on the 21st, there was a new software update. Although the update didn't call out signal strength specifically, but you never know... After playing around with the device, I flashed it with T-Mobile firmware. I didn't have enough time to test cell signal, but haven't seen issues yesterday and today. The signal strength is on par with my Pixel 2 and S10e
I've run speed test at the same exact spot with my Note 8, OnePlus 6T and Note 10+ and they're all just about the same, between 85-90Mbps DL.
I have one less bar at home but still managed to get 120mb download speed. Havent looked at the dbm readings. Elsewhere its been just as good as my s8+.
Unlocked N10+.

I am on Tmobile and also bought the unlocked (note+) version and ran the update. If you could be so kind, what does flashing the Tmo firmware do (and how do I do it)? Would this give me everything Tmobile puts on their phones? Is there a benefit to doing that? I am curious if that would help with the signal strength.

You just use Odin to flash TMobile firmware for note 10, you will have all TMobile bloatwares and features that built-in T-Mobile firmware. I believe you gain more signal bars. I also think you will be able to do video calling on your U1. I don't have note 10, still hang on with my note 9, N960U1.

So if you flash T-Mobile firmware on your Note 10, you will gain few features:
1) Advanced Messaging - be able to see when person read your sms, when it was delivered or when person is typing a message. You can also send images/videos of a larger sizes about ~10MB. This will only work when you text people that have similar software or that use T-Mobile
2) Video calling will be built in to the phone dialer app - works with phones from T-Mobile that use similar software(LG, Samsung, Moto)
3) Will have 4G LTE wording in the status bar instead of just LTE or LTE+
4) T-Mobile logo on boot and sounds
5) Practically no bloatware - after flashing, during phone setup, you will be asked if you want to install 3 T-Mobile apps: Visual Voice mail, T-Mobile account app and Macfee antivirus - just don't check boxes if you don't need them.
The reason I flash my phones with T-Mobile firmware is that, before releasing they test the update so it would work better on their network and that I have T-Mobile

AWESOME! Thanks for the reply.
I have noticed something about my signal. It may show one bar but compared to my Note 9, so far, it is blowing it out of the water with internet access. The building I work in has a metal roof and typically that spells trouble for fast browsing. The 10+ seems to be accessing sites faster. However using the GPS this morning I could have sworn it told me it lost signal.
*edit*
Forgot to ask...when flashing the T-Mobile firmware does that trip Knox? Is that still a thing worth worrying about?
I haave two conflicting opinions on flashing tmo firmware.
Thing One.
The carriers lie to us. That's why the tmo signal is better. Not because it's better, it's probably a marketing directive. Resetting the Calc of bars shown to dbm is not optimizing anything. It's making its customers not see dead zones and drop outs. Even though you still have no access on the device.
Thing Two.
But what if I'm wrong. Is it impacting my battery life having computationally lower bars?
Oh the madness.

I have zero bars now on N10 with T-Mobile band 66. Unfortunately I have no clue how to check bands on Pixel 3 phone, it gives be 4 bars of LTE
I have the same crap signal strength. My note 4 and 9 no probs. Changed sim card. Changed carrier, took phone To an authorized Samsung service center same problem. I find on Google that and saw how many others are having the exact same problem. The Samsung service center said they've been getting more and more calls on this problem and it's not a software issue it's a hardware issue. They told me there's not a hardware update, meaning there is not an antenna that can be replaced it's Built-in to the phone to where they couldn' change it out
flashprash65 : So are you telling us that we will never have a better signal than we currently have?
That we spent $ 1200 for a product that will never work properly?
