[Q]Data Speed Woes.

Just got mine on today from the retail store the guy activated a new Sim card for me and my data speed is terribly slow it doesn't even seem like it's 3g . Any ideas why its so slow?

what phone did you have before and how much did you use your data....could be tmobile throtteling

I'm only getting about 5-6Mbps which I would get on my MT4G... but it's the service in this area, not the phone's fault
HOWEVER
I am getting such bad upload speeds it's puzzling.. giving the phone time to adjust, I'll test again tomorrow because for some reason anytime I change phones the data connection seems to act weird the first day..

The phone in my store which is in a 42mbps area gets 15mbps with every test I did.

I'm getting 8 - 12 Mbps avg.

Just did a test right now and got 10,390 kbps using a 1MB file.
Seems pretty much the same as my HD2.
Remember that HSPA+ speeds are theoretical, the chances of you reaching those speeds are slim.

ok so after two t mobile calls and numerous network resets im getting absolutely ****ty speed test results. the browsing is ok but seems to be really laggy. hmm..
also noticed under settings/aboutphone/signal/MobileNetworkType i get UMTS and it will switch to HSPA randomly. could this be the reason? or should it say HSPA+? can someone verify this?

You won't get 4G speeds everywhere.

im aware of this..
i had a sgs4g which i lost 2 weeks ago and it was nothing like this.
it feels like my connection is capped at 56k

It could be the network, there could just be a lot of congestion. It happens to me sometimes too, one day I'll get 12mbps & the next I won't be able to get over 5. Try your sim in another phone if you can & see if you get the same results.

i used to get anywhere from 5mbps to 15mbps with the sgs4g.
im ashamed to say that i am getting half a mbps. lol

Speeds suck near Phoenix 2.4mbps

i talked to t mobile couple days ago, the technical support had to issue a ticket in order for it to get resolved. the lady said that my Internet should be back to speed in 3 days! Its not phone related its definitely a network glitch of some sort because i am getting 60 kbits. My very first bill cycle is days shy from being over and yet i have not been able to use 4g speeds.. even edge speeds is faster than what i am getting. I believe i shouldn't be held responsible to pay the web data portion of my bill for this month. its only fair.

Try this (if you haven't already).
Pull up your dialer, then dial
*#*#4636#*#*
Select "phone information"
Scroll to the bottom and select
Either "WCDMA Preferred" or "WCDMA Only".
This can be changed from the network settings also. However, I had ****ty data speeds at first too and, for some strange reason, the two menus did not match up... Using the dialer method it was on GSM and inexplicably went back to GSM on its own a couple times.
Hate to say... But if tmo says they are filing a ticket, most of the time the rep just exhausted what their knowledge or troubleshooting is telling them to do and a ticket doesn't change anything.
The GS2 should unquestionably whip the MT4G, HD2, SENSATION as well as most other phones in data speeds, consistently. I can say this from personal experience.
Interested to know how it turns out for you.

data speeds are eye popping!
This phone is great! I'm getting a whopping 60kbps/30kbps. We really standing still now! Tmo tech say everything is fine on there end so back to the store I go.

Sounds like your throttled, or your stuck in gsm/edge mode. Check to see also if your on gsm/wcdma, thts what it should be on. You could be on 2g/gsm setting. I put mines on tht setting from time to time.

I thought the same thing but tmo said I'm not throttled. gsm/wcdma(auto) is checked.
Thank for the advice though.
Edit: I put the Sim back in my vibrant and the speeds are the same. So I'm going with bad Sim or they are throttling me and don't know it. To be continued.

So they put in a work order and said they will get back to me within 72hrs. If it's not fixed I'm going to sprint. Tried the Sim in the amaze and sgs2 in store same speeds. Funny thing one of the questions asked while filling out the work order "do you tether?" Lol. Of course not.

I'm getting as high as 13mbps and almpst 2 upload speed. My g2x got half of that at best most of the time...

[Q] GSM Galaxy Nexus 300kbps

My 3g was working very slow so i downloaded this app called sppedtest.net and my download speed is around 290-350 kbps and the upload speed test gives an error it can't even complete, what is wrong with my phone, i have unlocked it officially

would flashing a new radio help?

Are you in a bad 3g area with your provider?

please help?

I'm using a CDMA Verizon Nexus and my Speed Test app won't even work half the time. When it does my 3G speeds never go higher than what you show. Have yet to have uploads past 100kbps. I'm on my second Nexus already.

It's probably the tower and/or the server you're testing on, not the phone.
My GN blazes:

I went from xxkk1 to xxkk6 radio and i get better dl speeds now.

funny thing is that i have the xxkk6 now, so this is a software bug?

????????????

can someone answear pls

please can no one help?i can't do nothing without wifi and i am paying for unlimited data plan for nothing

a lot of us are from the US here so we won't be able to do much to help you since your an orange subscriber. if you notice, most of us have usa companies in our sidebar.
as far as your issue. i don't think it's something with the phone. your best bet is to go into the orange store where you bought the device and talk to them about the issue and see whats going on.
i'm on T-Mobile USA, and i've had no issues with the speedtest app and have been getting on average 5Mbps down on 3G.

I have the same issue with my Galaxy Nexus. It is bought from Spain. I have tried all GSM radios, several ROMs, including the stock ones, nothing. The same SIM, in a Galaxy S II, on SpeedTest.net app (same server) gets 5 mbps, on my Nexus it never goes past 300kbps and it extremely jittery.
I suspect the phone is defective. What are your thoughts?

Your best bet is to call up your service provider and have them run through the settings of your access point names with you to make sure the settings are right.
If it's a hardware problem, you will most likely not be able to connect to 3G at all.

That gave me an idea and I found the problem. On each reboot Orange forces down my throat the settings and it defaults to WAP. THAT is why nothing works on mobile data; if I delete all APNs and manually create just the one for data it is fine.

Slow data speeds and spotty service

I've noticed spotty and inconsistent data/service on my phone. Even with full bars I get data speeds like shown in the attachments. When using the phone it will sometimes say I have no data connection and ask me to retry. I retry a few times and it finally loads whatever it is I'm loading. I've also noticed that my phone sometimes gets a little warm while in use. I've tried different modems with the same results and I'm about ready to just take it to the sprint store and get it swapped. Any suggestions on what might fix it? I can confirm that it is something with my phone because I've run side by side speed tests with my friends OG epic and their speeds are normal. Any help would be greatly appreciated.

Thats about what I get too. Its a combo of this phone and Sprints crappy network! My evo got better speeds as well.

I am getting the same thing too. Funny thing is that it just started being this way recently, it wasn't always slow. It is not just the data speeds, I am getting no service in places where I used to get service.
I have been seriously thinking about switching carriers and moving to t-mobile but a little afraid because I have been with sprint forever.
If something don't change by the end of the month, sprint may be losing another customer since the GSIII is on ALL carriers.
I am in Raleigh/Durham NC by the way.

I agree... it didn't feel so bad until I got my ET4G, but I just figured it was a network issue. I'm trying the EL29 modem on my Calks 1.6 now. If anything I'll try going fully stock and see if that helps.

Welcome to the Sprint network

Some people are experiencing network issues in places where Sprint is upgrading to LTE. I don't know how far-reaching the effects are but could possibly have something to do with it.

lol wtf

Yes, I notice the same thing lately with Sprint Wimax, I may have to dumb Sprint later. Sprint data speed gradually slows down from time to time, some area, Sprint shows only 1X, I look at friends' phones with Verizon, ATT and Tmobile, they have very good speed. My brother has Verizon LTE phone, I speedtested at the same location, he got like 17mbps download and upload is about 15mbps, mine is 1X speed. Suck, I gonna say goodbye to Sprint later.

Welcome to the Sprint network with the New iPhone4s d-bags. Seems like things were great till they showed up. Even my Evo got slower.

data
Maybe your phone is stuck in 1x..
What i do is i go into debug (##debug# in dialer) and i go to others, and then i select hdr/1x and i click on evdo mode. Try doing this but you need your msl.
Caution: ive tried it on ics roms and its really weird. Try going on a GB rom and do that. Oh and on EVDO, you wont be able to recieve messages, so when you are done change the setting back to hybrid.

NC market has some EVDO issues affecting certain users.
I was just told this after getting off the phone with them earlier today for a different issue.

Still incredibly slow, but I'm hoping the network update fixes some things. Thanks for the information though!

Werid 4g speeds, need help ruling out phone or network

I bought a Tmobile Galaxy S3 on new years from staples, and since ive got the phone ive been experiencing strange 4g speeds. While im in my house, I always have full signal strength, and it always says 4G. I live in the Bronx in New York City, and when the 4g is working properly, I get upwards of 20 megabits down, and 1-2 up. Now I could literally be sitting in the exact same spot, and later ill test the phone and it says 0.2 - 0.3 megabits, and like over 1000 ping and the up is so slow it doesnt even measure it. It usually comes back after waiting, turning airplane mode off and on multiple times or doing a battery pull. I find it strange that I can get either 21 mbps or 0.3 in the same house, while always having full bars. In the phone status sometimes it would say UTMS or HSPA, so it does switch from 3g to 4g sometimes. The thing is my previous phone was Nexus S with 3g and im pretty sure I never had a problem loading a simple image in my house because the internet was so slow. I consistently pulled 3-6 mbps on that phone. I tried calling t-mobile 3 times and they give me the same basic crap, like clear your cache, make sure airplane mode is off (really?) make sure youre network mode is on auto (i tried auto and wcdma only and it still gets slow) and all that other stuff. Is there anything else I could try to see if its a network or phone issue?

It sounds like it might be something with your local tower. I would call Tmobile and put in a repair ticket.

Thanks, I just did that. Called t-mobile and just directly asked them to check for tower issues, and they filed a complaint. They said to check back in 3 days, hopefully this gets fixed, or else it might be the phone. Do you think flashing different modems would change anything?

It wouldn't hurt to try. What are you currently running? (rom/kernel/modem)
Sent from my SGH-T999 using Tapatalk 2

Completely stock 4.1.1, with UVDLJA modem, which is the latest I believe. The phone is relatively new so I wanted to try touchwiz before I rooted. Does installing something like cm10 change the modem? Or is it independent of rom/kernel. I saw an application for tmo that can change between multiple modems pretty quickly, I might give it a try.

I work for T-Mo,
If I may lend my opinion,
To me, it definitely sounds like the tower. If you go from 20Mbit down to 0.2, and with 1000ms latency, it's super obvious there is something
wrong with the tower, or there is significant demand on the tower from other users, hey its NYC population density is insane.
Something to note as well, New York City is "in progress" for "network modernization" where they are switching to 1900Mhz.
This is why some people who have iPhones are now getting 3G in certain areas, unlocked devices, as well as AT&T phones can have 3G down there.
Due to this, since there is quite a lot of switching around going on down there, that's probably what's going on.
Example:
http://www.tmonews.com/2013/01/t-mobiles-network-modernization-what-is-it-where-can-i-get-coverage/
Hope it helps.

I see, well that makes sense. I dont really mind if its a tower issue because thatll be fixed eventually, I just would of hated if I had to replace the phone, it would of been such a hassle because I didnt buy it direct from t-mo. Thanks to both of you!
Also, since t-mobile seems to be using multiple bands for 4g, I guess it would be better to leave it on auto in network settings?

If it helps you at all to see if you are on a different band than 1700/2100mhz
You can go into the dialer and do:
*#0011#
Up top mine says band 4
Which is for 1700mhz AWS
BAND 2
which is for 1900mhz PCS.
You might be on band 4 or 2 on a tower by tower basis, or if they are making adjustments
You might be switched but that is above my pay grade lol

I have been on the phone with TMO about the same thing for over a month, plus my issue goes a little further. I will lose connection to a tower and not get texts or calls until I reboot the phone.
TMO had me replace the phone and SIM card, then opened a ticket with the Engineers in Las Vegas to troubleshoot, their response was that it was a known issue and would be resolved in the next weeks or months.
Everything ran fine until they pushed out the 4G LTE update, after that the service has been horrible.... even after that update that was supposed to resolve it...
I am wondering if there is a ROM out there that someone built to address this issue as I have about had it...
I am rooted but haven't thrown a ROM on it .... yet

Im guessing you updated your phones softwarem if so, you may want to downgrade to a 4g non-lte radio, and set yourself up on a 4g apn as well. It should help at least until rhey correct their tower issues. 4g is still pretty fast and at least your mms / signal will work as you will be back in the 4g towers instead.
Edit
Actually try this:
Settings--> wireless and networks / more settings --> mobile networks --> network mode --> and select the automatic 4G /3g /2g setting
Then go to access point names and add a new one. The only 4 lines you need to edit are as follows :
Name - Tmobile 4g
APN - epc.tmobile.com
MMSC - http://mms.msg.eng.t-mobile.com/mms/wapenc
And
Apn type - default,supl,admin,dun,mms ( no spaces inbetween the comas )
Give it a shot and let us know if it helps. It should force you back onto the 4g towers which use a different frequency. If you still have issues, then keep all these settings active THEN try an older 4G radio.

Go to this thread right here, http://forum.xda-developers.com/showthread.php?t=2102380 , & flash the last modem which is T889UVBMB4. I was using the T889UVBMD1 modem at 1st & was getting ok service but it just got to the point it was way to slow. I still go back to the T889UVBMD1 modem once and a while with the latest 4g lte apn but 75% of the day it is just way to slow of a combo. Like mentioned id also suggest flashing the T889UVBMB4 modem with the T-MOBILE US apn setting on this thread, http://forum.xda-developers.com/showthread.php?t=2208408 .

It's screwed from coast to coast. Been back and forth driving from california to pennsylvania, and the network is spotty on LTE within LTE markets, otherwise it runs great until it hiccups.
Seems like you get the equivalent of 'buffer overrun' issues from cd burning. Gert a bunch of data quickly, then stops for a minute to sort it out, then another data burst.
Seems like it happens to deliver a handful of megs of data, then practically loses network service for a few seconds, then another couple megs of data.
Just what i've seen running around nationwide.
LTE is fast when you find it though, nowhere near the speed of my verizon LTE service, but I can live with it.
Hopefully once they finish the LTE rollout it'll be back to normal.
