Band 12 on T-Mobile slow on the Z5 - Xperia Z5 Q&A, Help & Troubleshooting

Any T-Mobile users having poor speeds on band 12? I'm getting less than 0.2Mbps on my Z5, while my co-worker sitting right next to me is getting 7Mbps on his HTC 10.
I'm getting up to 40Mbps on band 4.
This only started around maybe two weeks ago. I could've sworn I was getting around 7-8Mbps on band 12 in the same spot (my office).
This make sense to anyone?
We're using LTE discovery app to check which band we're on.

how fast is at&t 4g lte ?

Im on tmobile and bought a htc one s bought really like how the htc one x looks and want to get it , i really like how fast tmobile 4g is here in los angeles, i get 18mbps down & 3mbps up , is at&t this fast or faster ? here in l.a of course
I'm not in LA but I have seen 35+ mbps. I see 25-28 often and average probably 15-20. The absolute slowest I have ever seen on this phone was around 8mbps which is still insane for a cell phone. Up is always around 10-15.

I second this. I'm also in the Chicago area, so I guess my post doesn't help sample size, though. But I also have been amazed at how much better my cell signal strength has been with the LTE. The 750mhz spectrum really helps get inside buildings and penetrate walls. I think this is something definitely worth taking into consideration, and often overlooked by people who are willing to settle for HSPA+. No matter how much your provider improves transfer rates on HSPA+, the signal strength isn't getting any better unless they physically add a cell tower closer to you - good luck waiting for that to happen - or you get onto a lower frequency band, like LTE here in the states.
~16 no LTE & 20+ LTE in Glendale
Not sure if there is LTE outside downtown & close proximity

I'm on a nexus s on t-mobile so my radio can't even take advantage of the faster HSPA+ but for me, in Portland OR, the coverage on tmo sucks compared to my wife's at&t (non-lte) phone. I'm just waiting for a kick ass LTE device with good dev support.
This is here in Phoenix.. this was the only screenshot I had but I get speeds over 30 mbps often.
I live east of LA downtown in the San Gabriel Valley... LTE coverage is very spotty still.
I know I'm not with at&t but here in Montreal with Bell I have around 50mb down and 19-20 up !
I visited Vegas two years ago, and ATT 4G (HSPA) network was horrible. I had great signal, but the system is so saturated that it was useless as far as data went. Phone calls i had no problem.
vegas was the same way when i was there in april. no improvement apparently. no lte in fresno yet but i thought this speed was pretty impressive. aprox 5 times faster than i was getting on my aria....

I'm on LTE all the time in the metro Atlanta area and I've never seen anything below 20mbps and I average in the upper 30's/low 40s since I updated to the 1.82 radio. I've hit over 60mbps on numerous occasions. Not sure if it's the new radio or if AT&T strengthened the signal but I never got LTE at my house but now I have full bars and great speed. I live about 50 miles north of Atlanta also.

I'm surprised they haven't already, we got it recently here in Oklahoma City and it's been wonderful. I imagine it's a lot more work to deploy a network there due to Seattle's topography and building density.
Granted its 1 A.M.
I never get under 40 mb/s here in south Fort Worth.
I'll take my hspa+ 42 over any lte provider right now, the fact remains lte coverage isn't nearly as good, sure it works in some area's and yes its blazing fast, but anything over 5 down on a cell phone is gravy, and over 10 when tethering is just fine.. Went on a road trip about 500 miles from ft. Lauderdale to Tampa with my friend who has verizon gnex, and my gsii on Tmobile... Lol he lost lte the second we left the city, while I tethered streaming netflix/sling player... So yea, hands down ill take coverage over speeds that aren't even needed... My parents have a second home kinda on the outskirts of a boondocks city, my dad replaced the Internet there with his phone, and he sees 21 down and 3 up...
Also, let's see how well lte works when all of a sudden 35% of the cellphone market, almost 80% more users on lte, start using it within one day.(iphone5).

Not LTE, but I think its impressive for HSPA. IMO.

How to check lte band?

Hey everyone. Just picked up my one today and the new aws network is rolling out in my area and I'm trying to figure out which band the phone is connected to. I could dial *#0011# on my s4 and it would tell me band 13 or 4. Anyone figured it out?
Sent from my HTC6525LVW using Tapatalk
id like to know too. i watch my band on my note 3 same way as your s4 and comes in handy
Nobody knows?
Sent from my HTC6525LVW using Tapatalk
I've been doing some research and I've only come across the stuff for the Note3 and S4 you mentioned....and IOS has a hidden field test menu that also tells the band you're on.
I'm definitely on Band 4 in Newark NJ....DNA gets 1-1.5 down and 1-2 up M8 gets 20 down 7-15 up
Though my DNA gets better reception -94 to -96 than my M8 -101 to -104

Yeah if I was the only human being in Newark! considering the DNA is choked at 1 meg down I'm pretty positive my M8 has to be on band 4.
Even with that I'm sure there's a ton of note 3 and s4's on it as well.

Lollipop enables band 4 XLTE

Not sure if this information has been posted...
http://www.phonenews.com/verizon-ht...te-enables-band-4-xlte-coverage-access-30047/
Verizon has begun rolling out the long awaited HTC One M8 Android Lollipop update to owners of the smartphone this week and in the process, enabled expanded access to its LTE network by activating the previously dormant Band 4 (1700 AWS-F band) for access to its XLTE high-speed network overlay. This update is expected to substantially improve coverage for customers that have been dealing with network congestion on the primary 700Mhz LTE network. The carrier is rolling out the update in waves and has posted a*detailed changelog*with the changes on its support page for the phone.

Its dated for about a week ago so I'm gonna say its the update we just got. I don't know what app we could use to see what bands are active or enabled. I'm sure there is something out there though.
Maybe it was Viper ROM but I am pretty sure mine has been active as of kit kat....as I can get speeds of 70-80 down in areas that only used to be 5-10

Hm, I had band 4 when I was running Viper and some other ROMs as I recall. I wonder if it enables Carrier Aggregation with band 4, which I asked last night in Q&A section.

Well depends on where you live....nowhereville Montana isn't getting xlte deployed as quick as metro NJ..but even then I'll get crazy fast speeds at work but if I walk a block away I get only .3 on LTE! So even in highly congested areas they haven't upgraded to xlte.
Use LTE Discovery app if you want to know what band and cell you're on. It's very useful.
"Lte discovery"app says I'm on lte band 13, guess my areas not band4 yet.
Same here in Tennessee
LTE Discovery is a real winner of an app. It's what I use as well.
Band 4 XLTE in central Virginia working like a charm.
Correction the cell tower on the other side of town is xlte band4 30Mbps up/10Mbps down

I thought the same thing...but if you follow the moving arrow (ex. turn your phone around in circles like a weirdo...you may eventually change to XLTE band 4 (happened to me after about 60 secs). Until this cool app I just tried bc of this thread...I didn't even realize XLTE was rolled out around here yet.
The XLTE tower must be far away though, bc I only get 1 bar of XLTE and my speed tests suck when locked on.
Speed Test XLTE: 18.69 D | 1.05 U
Speed Test LTE: 22.64 D | 11.68 U
Speed Test WiFi: 127.31 D | 44.21 U (screamer!)

Sprint LTE plus

Hi all,
What have you been getting for download speeds on Sprint's LTE plus?
I'm in Chicago's south suburbs and have been averaging 12-18 Mbps according to the speedtest app. I checked the coverage map and everywhere around me in in the LTE plus zone. I really thought it would be better.
Maybe it's not implemented around me yet. I was getting about the same speeds on my note 4.
TIA
Meh ... Phoenix
I went from 14ish (s7e) to 20-40 depending on where I the area I am.

T-mobile 5g with the S8

I will start off by saying I live in Seattle, the homeland for t-mobile. I was wondering if anyone else is experiencing 5g actually being slower than 4g. Not just by feel, but by statistics and facts.
This is the case for me. Now I understand 5G is not global yet, but I think New York has it. I am getting about 21mbps download and 12 upload with 5g. On 4g, I am getting 41mbps down and about 12 up.
My Wifi at home gets 475mbps download, and 25 up. Anyone else experiencing this problem? Thanks.!

Just got my OnePlus 8 Friday In Peoria just outside Phoenix and most of our cities are 5g tmo ready and getting the same have not had one test where 5g works faster then 4g..
I dont think it has anything to do with T mobile having its headquarters in Washington...
I think it was more John Legre blowing typical marketing smoke and some of us fell for it!
With full bars for me, I get 80+ mbps on 4G LTE and around 110 mbps with 5G. I live in Akron, Ohio. From what I've read, the (600 MHz sub-6) 5G that T-Mobile offers is more about coverage than it is speeds. mmWave is more for speed.

Are you able to post your speeds?
I live in Boise Idaho and just got the OnePlus 8 yesterday. I ran speed tests on my OnePlus and the 5G seems to be anywhere between 30mbps-60mbps faster than my 4g LTE is ?* Don't pay attention to the first test. That was on the outskirts of my town and I only had barely any service, just wanted to test it to see with basically no service how fast it could go.
I work at a Tmobile store so I think I can help a bit but I’m not speaking for the company. So your phone is working fine Tmobile has 3 layers of 5G: Low band , Midband, And High band. Right now the current 5G that is available across the country is low band the speeds are slower but you have much better coverage, with the sprint merger they will next be rolling out the midband which will give you better speeds but not as great of coverage as the low band. Then they will roll out the high band which will be super fast but not very reliable (Verizon uses only high band and the signal can be easily blocked) right now in NYC they have working on all 3 layers at once and eventually that will expand. The benefit of being on the 5G network right now is that it separated from the LTE users so there is a lot less congestion.
I'm in Philadelphia, PA and my 5G seems way slower than any 4G ever was.
Also close, just north of Seattle. I'm on ATT MVNO Consumer Cellular now as their LTE speeds are better than T-Mobile around here.
I tried a Mint Mobile 250MB trial SIM and drove around testing. I was connecting to normal LTE bands (2, 4, 12, 66,.. Couldn't connect to tasty 71) running 5G protocol. I ran through the data quickly but speeds seemed to be on par with T-Mobile LTE. Cell speeds around here have always been pretty congested.
I can't get Consumer Cellular to connect to ATT 5G with ANY combination of settings but that could be maybe OP8 IMEI must be whitelisted with ATT (thought they just did that) or Consumer Cellular doesn't allow 5G even though an old site page says they will.
In the pic the 5G one is the only T-Mobile test I actually ran outside the Google speed test page. Red icon is using single connection (more realistic) and green is multi connection.
For now I guess ATT LTE still faster.
Also what is 5G Smart Switching (or whatever) in settings page?

Sorry, just saw this. Been hella busy working on the house while the government recharges all the birds. ? When I get to an area where I live that has all bars, I'll post the speeds on 5G and 4G for you. My buddy just switched from Sprint to AT&T (iPhone 11 Pro Max) and he hit 186Mbps. Irrelevant but just still BS.
We are just changing the protocol using existing radio bands. Near 200 Mbps is the speed of my Comcast WAN. Outside very large single file downloads what would you need higher for? Not scrapin' just curious.

Having high download/upload speeds are nice especially if you stream games with your phone like I do. Regularly use Xbox Game Preview, GeForce NOW, and Stadia. Although I wish Google weren't such suckas and let you stream over LTE but hey, what can you do?
Here are my speeds taken directly after the 10.5.8 IN55CB update. 4G LTE, 5G, and WiFi.
Tmo speeds are abysmal in Dallas fort worth of anyone is wondering .
I'm talking much slower than lte, seriously around 15 to 27mbps if you're lucky. I only upgraded from the 7t for 5g and it's a joke.
Just FYI tmo says that's normal and to be expected too... ??
No I'm at anywhere from 45 to 70 mbs download and up to 40mbs up even with a vpn I. Seattle
Decent speed down at the Des Moines/Federal Way border. On 5G.
You guys are killing me! I'm an hour east of Atlanta. My LTE reads 16Mpbs and my 5g reads 31Mpbs. So it's definitely faster but waaaay behind you guys.
Great speed on 5 G. TMO added two more bands and it is blazing fast.
