note 10 plus 5G for tmobile - Samsung Galaxy Note 10+ Guides, News, & Discussion

Anyone know if tmobile will get the 5g? I really see it as an upgrade from the note 9 if im getting 5G.
Or will the Verizon 5g model work with tmobile future 5G bands?

I believe 5G models for the other carriers will trickle out later this year or early next year. By the time T-Mobile builds out their 5G network to the point I need a 5G phone, I'll be on the N11 or N12. I wouldn't worry about it.

All the other big 3 carriers will get them. Verizon have a 3month exclusive on the 5G handset.

Qualcom is working on newer 5G modem, due to come out in the next few months, maybe it will find it's way into non VZW Notes. Personally I don't care, I'm on 200Mbs Wifi most of the time, which is fast enough for everything I do and otherwise I usually get 50-100 Mbs LTE signal, which is fast enough even to stream 4k video. At least in my experience most of the time limiting factor in download speeds is originating server, not the network speed, so 5G may not make as much difference as some hope. Also, once the 5G networks get expanded and many people start using it, they better upgrade infrastructure beyond 5G network, like servers and interconnects, because any network is as fast as it's slowest part.

Possible use on Verizon LTE network at full speed?

Thinking about this as my next possible upgrade, been with a Note 3 for about 3ish 4 years it feels like. After the bootloader got unlocked I had few reasons to upgrade. Now however the hardware is getting dated and this looks like a viable upgrade. Would this phone work on Verizon's LTE network at full speeds, I am assuming there will eventually be a CyanogenMod released for this and then all I would need to do is unlock it?
Don't count on it
It's sadly not that simple from looking into it for the Mi5... However if they make great progress with the Mi5 there could be hope for this device as well since the 820 and 821 have few differences (or none? just an OC?).
The Mi5 is able to make calls and text at the moment but the LTE is still a bit unstable. If this looks like it will get enough support I might choose it over the Pixel XL. And if it works on Verizon since I still have my unlimited data plan.
I'd like to see B2, B4 and B12 LTE bands unlockable. I'm guessing monitoring progress on the mi5 is the right move since they have similar hardware profile.
Hopefully the chip can support the bands, otherwise it's another great phone that wont see it's potential in the us/eu market.

mmWave worth it?

Looking to go from an S10 to what I thought would be an S11 but I guess is now called an S20. I'm wondering of it's worth it to go for the monolith of a phone in the S20+ version or get the regular S20 and miss out on mmWave which apparently does not come included with that version. Has mmWave been fully implemented yet and is it worth it? Or is it just in its infancy and I would be paying for a feature that will never be used? Hopefully the big brains here on XDA know more about this than I do. FYI I'm mainly in New England area and have T-mobile for a carrier.
Depends on your carrier. On verizon, used the most while tmobile is in like 6 cities and just few blocks
Dont worry about mmwave, its kind of useless unless you're standing right in front of the tower, assuming there even are any towers in your city. And then what are you going to do with all that bandwidth?
Yeah I figured as much. I think there are zero Tmobile towers and from what I heard Verizon only is around the Fenway area. Thanks y'all.
Reading up on mmWave tech I don't see this to become a standard like LTE has. If you think about it LTE is PLENTY fast and I don't see LTE tech going away anytime soon. mmWave is VERY short range and while the speeds are ridiculous, I really don't see the point to gigabit bandwidth on a phone - again 4G is very fast provided the tower isn't overloaded.
By the time 5G is ready to roll we'll be onto the S22....
I agree, mmWave is going to be mostly useless for now. Just about the time this phone gets old to you, mmWave may be much more mainstream and much better options will be available. The only real way I could see mmWave useful right this second is if a mmWave tower is right outside your house.

Sprint S20 5G on T-Mobile

I have a Sprint S20 5G flashed with the U1 firmware, and am just trying to make sure that I am taking full advantage of T-Mobile's Network? I thought that the hardware/radio bands was identical across the different U variants? The icon at the top, which I know can mean nothing, says 5G. But in settings the network is showing up as LTE. The LTE Discovery app is showing I'm on band 66, but it also says 5G NR: Connected! It looks like my area should be well covered in 5G, so I was hoping to make sure that I'm taking full advantage, or at least am able to?
Is there any advantage to flashing the T-Mobile firmware?

No point in flashing U instead of U1. As soon as the phone boots with a SIM, it performs another session and gets tuned to the network by the SIM. Your channels and speed will not change. BTW , I talked to a TMO service and support, and right now although 5G, speeds in most cases are at the 100M byte range. Only few lucky ones may see 1Gig if they are out in the open on a mmWave channel . However this technology is aimed at the next years for autonomous driving and other new technologies, not so much for phones, and it will not have reception inside buildings (heck, holding the phone will most likely block that signal without external antenna, and it comes from an engineer here)

no offense but engineers dont always know what theyre talking about.. tnobiles nationwide 5g network penetrates well through buildings and avg speed for it is less than 100mbps.. to get 1gbps needs to be on a different 5g network (i forget what its called) which will not be bationwide or have good penetration since it has low range and needs a lot of towers in a small area so will likely only b used in major cities so seeing as hes getting over 100mbps on tmo 5g is better than average and is definitely 5g

Thanks. I found out from another user, and by looking up in the service mode with a dialer code, that I was actually picking up 5G through T-Mobile band 66 connected somehow with band 2 or 71. So all was well. That speed I got was surely plenty fast for me.

You just said what I claimed. The only 1GIG speeds are om mmWave bands, and like 90% of us seeing 5G icon are on the 600Mhz long wave that is 100M speeds, or the medium wave , again 100M speeds. I get 5G all day long, and never more than 200Mbit once, and 60-100Mbit otherwise. No mmWave where I am .. so we say the same thing.

Except that T-Mobile isn't implementing mmwave 5G, now or in the future. mmWave is only Verizon. And only Verizon's version of the S20 models has the radio and antennas for mmWave. (That's why the Verizon one has less memory - it needs many more antennas to make sure your fingers don't block the signal, and those antennas take up too much room.) So you will NEVER get mmWave 5G on your T-Mobile, Sprint, or unlocked S20. Even if you put a Verizon SIM in it.
T-Mobile's existing 5G is low band, and slow. They're migrating to Sprint's mid-band network which will be a lot faster than the existing network, but nowhere near Verizon's. But you'll be able to actually USE it, unlike Verizon's which will never exist outside of cities and major suburbs, and doesn't work worth ****e indoors unless you have a repeater.
mmWave is going to go down in history with WiMax as a bet on the wrong technology.

Not sure where you heard all of that but it is incorrect. Tmobile is deploying mmWave and both the Tmobile and Sprint S20s will support it.
AT&T also uses mmWave and on the S20s as well.

Oh interesting, good to know.
I don't really care if I have it. Our LTE+ is roughly 200ish down and good coverage.
5G at this time is for the most part a marketing tool for manufacturers and service providers but lots of prospective users are buying into the hype. LTE is comparable in speed to low and midband 5G and in some cases even faster. Until mmWave is widely avaliable, which won't be anytime soon, 5G's biggest asset is it's marketing appeal. All hat, no cattle!

Question Can I switch to Verizon with this phone?

It seems most of the 4G and 5G bands are compatible. I'm just not sure about 3G with the CDMA vs GSM. My service through TMobile just hasn't been good enough.
Thanks!
2125 should work fine. 2127 may or may not work. The rest will not work
Verizon's network is mostly 4G or newer nowadays. CDMA will be a factor in coverage but it's minor. I occasionally will pop into the Verizon network with a random device if I know it's compatible with the bands Vzw use. Pop in a sim and give it a whirl.
I'm using Verizon on my 2125. My coverage and service speed is way better in my area than it was with TMobile. Calls texts and data all work fine.
Hi, I'm using Verizon with this phone. No issues at all. My phone usually is on the 5g network, sometimes on 4g. Only thing is that voice over wifi does not work. Besides that service is great.
VoWifi doesn't work. I haven't found a way to enable that on Verizon. Everything else works fine for me. Speeds could be better but that's probably just my area.

CDMA is not a factor in any LTE or 5G phone. Verizon requires a flag CDMA_Less for this phone. Others that are Verizon phones have that set automatically in the back end. This flag has been required for correct functionality for at least 3 years.
I loved VZW and been with them over a decade. I recently switched to T mobile and it was for one reason only. VZW sold many of their towers and TMobile bought them. Tmo used to suck. Service and customer service. But they did one thing. They offered NR..VZW has already admitted that their 5g is a combination of 4G and 5G. UW is available but you will find that to be very limited. 5G is just a marketing tool. The consumers get the short end of the stick and the lawmakers allow the FCC to change the definition of what 5G speeds are. VZW sells the OnePlus 8 5g, will allow the OP9 and OP 9 pro to work. Also while your phone will work on VZW it will not have the correct radio in it to truly take advantage of 5G. This article will explain it
OnePlus 9 Pro Is Now on Verizon, But You Might Want to Stick With Samsung
Although the OnePlus 9 lineup is now certified for Verizon, spectrum limitations, setup bugs, and other oddities mean that a Samsung handset may be the better choice for those not committed to the OnePlus brand.

Uhhhhh, what? None of that is actually true. And that article doesn't "explain" anything. It's literally not saying anything close to what you are.
Perhaps this will explain it better. There's a reason VZW isn't selling the OP9s. VZW has invested heavily in c-band while T-Mobile is utilizing the low sub 6. The OP9 doesn't have the c- band capabilities since most of the world is doing mm UW and sub 6.too tired to go any further. Most people on VZW had to shut 5g off because of the latency issues. If VZW does indeed sell the Op9 pro it will be c band compatible but will be more expensive to produce. Again I didn't switch to TMobile because VZW did something wrong. I switched because if I'm going to buy a 5g phone in 2021 I want it to work in 5g now not in 2022. VZW is late to the game in true 5G. And they had a net loss of subscribers because of this. Personally I do not like tmo. I don't like their CEO especially so im not knocking VZW.

Your post still had no basis in reality whatsoever. I don't give 2 ****s about Verizon, I'm not trying to defend them. I'm just saying you're spreading completely false information.
Here, I'll break it down:
Verizon sold their towers and T-Mobile bought them? That's... just not accurate at all. Are you talking about this?
America Tower: T-Mobile co-locating gear on Verizon towers we bought
American Tower sees a strong future ahead for its portfolio of cell towers it acquired earlier this year from Verizon Wireless, according to an American Tower executive. T-Mobile US, in particular, has been looking to co-locate its network gear on those towers as it expands its LTE network. |...

Verizon leased their towers to a 3rd party company who then sublets the towers. You DO realize that each cell tower holds multiple carriers, right?

"admitted". So is T-Mobile in a bunch of areas. And AT&T. Also, you're thinking of SA and NSA (standalone and non-standalone), not NR. NR (New Radio) allows for SA and NSA, and it's a Qualcomm thing, not a Verizon or T-Mobile thing.

Lawmakers and the FCC don't change "definitions" of "5G speeds". Nobody does. 5G isn't determined by speed at all. 5th Generation connectivity. It's how phones connect to the towers, not what speeds they run at. If you're getting 1mb/s on a 5G tower, does that mean you're on 3G? OF COURSE NOT. Just like if you're connecting at 200mb/s on LTE, that doesn't make you "5G".
Also while your phone will work on VZW it will not have the correct radio in it to truly take advantage of 5G.

I really don't think you read the article you linked. The only thing the OP 9 and 9 Pro lacks is wifi calling on Verizon. MAYBE you're trying to say the 9 won't connect to MM-Wave while the Pro can, but it's like that on every carrier. The 9 won't connect to T-Mobile's MM-Wave either. Now, the article DOES mention that the 9Pro won't SAY it's on MMWave, because it's missing the ICON. The Icon.
Insiders tell me that OnePlus could fix this by adding a Verizon "icon pack" to its firmware. I've asked OnePlus for comment and I'll update this when I hear back. The phones also don't work with Verizon's Wi-Fi calling feature. There's just no option to turn it on. Verizon tells me there is no plan to add that, at least for now. I've also asked OnePlus about that.

The C-Band auction literally ended what, 3 months ago? Verizon and T-Mobile don't even plan on rolling it out until late 2022. Why would they sell phones with it NOW? Also, the "rest of the world"? The EU hasn't rolled out MMWave yet, as they just ended the first rounds of spectrum auctions. MOST countries barely have any 5G, if any. And that's fine, because 5G is mainly about capacity, not speed. And they don't need the capacity right now, LTE-A is working fine for them.
Also, you're confusing C-Band with the existing mid-band spectrum that T-Mobile acquired from Sprint, which is used on band 41 and is known as the "faster" 5G (though still slower than MMWave). T-Mobile's low band 5G isn't about speed either, it's about capacity. You're lucky to get over 75mb/s with their low band stuff. Just like Verizon. Go figure. The lower bands have slower speed and reach further, that's just how physics work.
Most people on VZW had to shut 5g off because of the latency issues. If VZW does indeed sell the Op9 pro it will be c band compatible but will be more expensive to produce.

Again, NO carrier has C-Band deployed right now, and won't be deployed in any large scale for at least a year. Why would they make a 9 Pro with it later on when it will be at least TWO models behind? (The 9T and the 10, possibly the 10T as well)

Verizon has been losing customers to T-Mobile for years now. It doesn't have anything to do with 5G, it's about being priced out of the budget market. They want to focus on ARPU vs number of lines, while T-Mobile took the opposite approach, hence them giving out free lines right before every earnings report.

I believe it should work as long as your phone is unlocked, whether it's a tmo or global phone shouldn't matter much except of course for adding some tmo specific bands.

Basically, but not exactly. There's a reason global converted OP9P from tmo must reflash the tmo modem for each OTA.
Since OP already has the 2127, worst case is you give it a shot and see if it works. Maybe it will, may not.

Question 5G slow upload speed

I have the EU version of P6P, the one without mmWave, anyway, not an issue, as mmWave is not supported by my carrier.
I have very good download speed, but upload is no more than 5-6 Mb/s.
Do you have any suggestion, please?
Likely expected behavior. Most mid-band 5G spectrum is TDD and allocated to favor downlink.
My Pixel 5 was significantly faster than my Pixel 6 Pro on 5G but even so i see 70 or 80Mbit uploads, that said i have also seen a 0.69Mbit 5G upload so it isnt always great.
It all depends on what is around you (tower wise) and which phone carrier you are using. Most people who use 5G don't see those lighting fast speeds that are often advertised. It'll presumably take a few more years before a larger chunk of us reach those speeds (due to new towers, new bands being activated and new phone modems being manufactured and utilized).
