Galaxy Nexus works on T-Mobile 3g/4g?

Hi all. I'm thinking of getting the Galaxy Nexus on my Tmobile. Thing is, I have the GS2 and the 4G has spoiled me. I'm in NYC so coverage is pretty good. What I want to know is whether or not T-Mo's 3G works on GN. Reading about it and I have conflicting answers. Thanks.

tmobiles 3g is GSM and will work just like at&t. The 4g is LTE and will not work on the GSM galaxy Nexus. LTE is CDMA based like Verizon and sprint

He is asking if T-Mobile "4g" works and yes it does but it isn't as fast as the SII.

It certainly does my friend. As long as you have the GSM version which is pentaband. You can't use the Verizon or future att one coming out .
Right now its Verizon or GSM and gsm is the one u need.
Its capable speed is 21 versus 42 on gs2 but difference shouldn't be big at all

He said 3g lol. Anyway, I thought T-Mobile had 4g LTE.....how would that work with the GSM GNex? Do they also have HSPA+ like at&t? Cause that works with the GSM GNex

Yes T-Mobile has HSPA+.
The Galaxy S2 for TMo theoretically can reach speeds of 42Mbps but honestly... you won't reach anywhere near that. The Galaxy Nexus reaches theoretically up to 21Mbps on T-Mobile.
In the end, it does support HSPA+ (4G)

I put both because I realized that T-Mo doesn't have true 4G. So it looks like I will be getting this after all. I had a Nexus S prior to the GS2. Am missing that "Nexus" feel. I also read that there are different builds out. One or two are getting updates via Samsung and not Google. Which build should I be on the lookut for?

I had a Nexus S prior to this phone too.
You would want the 'yakju' build, but you can convert any non-yakju build (as long as its not mysid) to a yakju build.
If you use custom ROMs, then you won't have to worry. I honestly don't know why people want OTAs, but that's up to them. I personally use custom ROMs and custom kernels to get the most out of my phone.

HSPA+ is more like 3.5G than 4G, but T-mobile is calling it 4G.
The GSII can consistently reach speeds of 20mbs, while the SGN only gets speeds between 2-9 mbs.

It is 3.5G but it's marketed as "4G."
Galaxy S2 can reach up to speeds of 21Mbps. BUT the T-Mobile version can reach up to speeds (theoretically) of 42Mbps because it uses a Snapdragon instead of Exynos.
GN reaches 21Mbps. Not 2-9. These speeds are all theoretically speaking as we weren't talking about "real speeds in real time."
Don't understand why you quoted me and reverted everything I said when everything I have said about about Galaxy S2 is a fact.
Sources if you don't believe me:
The magenta carrier is in the process of rolling out an enhancement to its HSPA+ network that will allow theoretical maximum speeds of 42Mbps. The Exynos board in all the other GSM Galaxy S2 devices uses a separate radio that is only capable of 21Mbps. T-Mobile wants to have devices capable of taking full advantage of the newly enhanced network.

I agree. I don't understand who would be rushing to import a non-subsidized GSM Galaxy Nexus and not plan on immediately rooting it. The Verizon phones, ok, someone walked in and walked out with the "latest Android phone". Still, the vast majority of the nexus owners, especially anyone who visits xda-developers.com will be rooting and flashing if not true "you need a 12 step program" crack-flashing.

Poor performance on SpeedTest.net (GSM version)

Hey all,
I live in Chicago and have a GSM version of the Galaxy Nexus using the T-mobile network. Honestly I have never gotten more than 10mbps download and often get less than 5mbps. My ping is also very unstable sometimes its 1000+ or its 100. Is there something wrong with my 4g radio? As a comparison my gf's Samsung Galaxy S II gets 15mbps or better.
Thanks

Here in Baltimore my tmo galaxy s2 pulls 10 to 12 mbps and my gnex on tmo only gets about 5. Don't think there is really anything wrong with the gnex radio. Its just not best suited for tmo network as good as the tmo branded sgs2.

does your gnex show 3G when you are not browsing and then switches to "H" when you are?

Try flashing some radios. Ug--x radios are for north America but it seems a lot of people do better with Europe radios on T-Mobile which are XX--X.

Try different radios to see if it helps. The T-Mobile SGSII will always get faster speeds because its a 42mbps HSPA+ device, whereas the GNex is a 21mbps HSPA+ device.

[Q] Not getting 4G on GSM Nexus

Hey guys I just got my Galaxy Nexus yesterday and I've been noticing that I am not getting 4G or 4G speeds in the areas that I used to with my Galaxy S 2. Just so you know I'm on T-mobile. I haven't seen 4G or a 4G speed once. What's going on? I'm running CM9 Nightly

GS2 and galaxy nexus do not have the same HSPA radio
GS is 42mbit
GN is 21mbit
also the icon on the GSM GN is just H

Oh dang. Well that really sucks.

GSM Nexus do not have LTE radio, you need to get the LTE Nexus, which i believe is carrier locked.

T-Mobile USA doesn't have LTE, so it doesn't matter what device he gets.
OP, what are your speeds? Sounds like you're falling for some serious marketing speak. The T-Mobile branded SGSII has 42mbps HSPA+ radio compared to the 21mbps HSPA+ radio in the Galaxy Nexus. Real-world speeds will be a bit lower, that's just how it is.
Also, the Galaxy Nexus doesn't have a "4G" icon. When its connected to HSPA+ you'll see an "H" icon. It'll be connected to the exact same network. Its just an icon.

I understand that. I just though the gnex was 42mbps hspa. I'm getting 3-6 mbps real world whereas before I was getting 9-15

hmm. Well that's too big of a gap to blame it on the radio. I easily post 9mbps on mine. And the blame is all on you. Its extremely well documented this device is 21mbps.

I get like 5-6Mbps on ATT, but that's the Max I ever get with all my phones. So its normal for ATT I say.

I am really curious about this as well. I have speed tested a GSII and a One S and seen speeds around 20mb, where I get a consistent 3.5mb in the same place with my GN.

Okay, 20mbps on T-Mobile? Sorry, don't think that's a standard consistant speed you can reproduce. There's no way you held a SGSII and a GN next to each other, one getting 20mbps and the other getting 3.5mbps. Something is wrong there.
Realize the speeds are different, but cmon. I get 7-9mbps on my GNex + T-Mo no problem.

The review of the one s on tmonews shows consistent speeds of 20mbps+.
I know the One s is "42mbps" but I do sometimes wonder if they are holding non-tmobile phones down.
My sensation speeds were crap when I moved from the nexus one initially. I changed my phone on my account from unknown to the sensation and I was getting consistent 7-9mbps instantly. The sensation is only 14.4mbps.
I rarely get 9mbps with the GNex.

Yeah, I know there is something wrong, that's why I have been asking around. And to be honest it was the One S that was hitting 20+ consistently, the GSII hit 14-18mb while I never hit faster than 3.6. If anyone had anything helpful let me know, I have already tried two or three different radios with no noticeable difference, and I have read about some kernels having a data speed lock problem, so I tried different kernels with no noticeable difference as well. And in the end, I have never hit any higher than 3.8 download speed with my GN here in Reno and we do have the 42mb towers.

I get over 7 Mbps easily. Phone set to unknown on my account. highest was 11 Mbps xxla2

I always thought that as long as the tower back haul is not maxed out, a 21 Mbps and 42 Mbps phone should get identical speeds as long as you're not hitting any of the limits. So I mean if the 42 Mbps phone pulls down 15 Mbps, then the 21 Mbps phone should also pull down 15 Mbps, up till the 21 Mbps limit.
So I'd say its artificially limited by T-Mobile giving preference to their phones over unlocked phones. Or some wrong apn setting.

Is it normal/acceptable for "4g" speeds to be less than 2 Mb?

About a month ago my area upgraded from EDGE to HSPA+. I finally decided to play with the speedtest.net app yesterday and I was only managing download speeds of maybe 1 or 2Mb, on a good test. This is enough for casual use, I suppose, but most people (on this board at least) seem to be getting much better speeds than that. A nearby area where the State University resides also produces similar speeds on my GNex and my previous phone (AT&T Galaxy S2).
Is this normal or do I need to change something on my phone?

1-3mbps is pretty normal for me indoors with 2-3 bars of signal, with 4-5 or so outdoors with better signal. I can only pull down those crazy numbers of 10+ with HSPA+ late at night when the towers aren't as busy. I'm in a small town, but we've had HSPA+ for a good year or more now (heck, I was on Verizon when it was switched on, so I don't know exactly how long...). Maybe your network is still getting upgraded / installed and the process isn't done yet?
I'm on the T-mobile $30 plan, by the way. I've heard AT&T's HSPA+ can be significantly slower in some places, so that may be part of it?

if they just rolled out the towers a month ago and upgraded to HSPA+, I'm not at all surprised by those speeds.

Att's hspa is notoriously slow compared to Tmo. I see between 6 and 18 mbps on my Tmo phones and my Att phones max out at around 6, averaging around 3.
For an area that just now got hspa turned on when the rest of the country is getting LTE, those speeds you are describing seem perfectly normal.

I'm on T-Mobile and 1-2Mb is normal for me with 5 bars. If I'm extremely lucky I sometimes see 3Mb.
T-Mobile's "4G" in Phoenix is exactly the same speed as my 3G Vibrant.

I would be happy to get 6Mb down with AT&T in Austin. Max is about 3.1Mbps which I think is crap since we know it is capable of more. Interestingly, AT&T LTE in the same areas rock!

Well that's also because T-Mobile has HSPA+ 42mbps deployed, and devices that can make use of it. Most AT&T devices are at best 21mbps capable, and not all of their towers are.

Depends on signal strength. On VZW LTE I can pull 20+ mbps in Seattle, but only 2-5 mbps in outlying areas.

"4g" in quotes, and OP specifically is talking about AT&T.

I'll have to run speedtest some more when I'm out of town and see what kind of numbers I can get. I would be interested to see what speeds a 3G phone gets in the same region as my "4G" Gnex (HSPA+ via AT&T, not LTE via Verizon).

[Q] Throttled 4G Speeds

Anyone else having insanely slow 4G speeds on their Android devices after the iPhone 5 release? I did a side-by-side speedtest on the same server, 35mbps on the iPhone 5 and 5mpbs on the Galaxy Nexus.

I do believe the iphone 5 is lte and the galaxy nexus is not, just hsdpa. The lte network also has fewer phones currently due to being new and only in few markets.

The 2 cdma (sprint and verizon) variants of the galaxy nexus in the USA are lte devices.
@op, no. On verizon results are right on par with previous speed results with lte on the nexus.

If LTE was being affected, it would slow down speeds for both phones assuming they're in the same place on the same network (and tower). The iPhone doesn't have its own separate network...
One phone getting 35mbps and another 5mbps is a fluke. They should both be roughly the same assuming they have the same signal strength.

Yep

verzion bc it has many tower... if there is no tower close by then you will not get 4g or 3g u will be on edge..
how i know.. my co-worker called up sprint to see whats wrong with his samsung galaxy s3

Is it possible the account for the nexus is in the 5% that gets throttled on high traffic towers?
