[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...

Am i the only one with 4G problems?

Looked in General and Q&A and can't find anyone complaining about 4G reception. This stupid phone doesn't hold 4G indoors ANYWHERE I go. My Galaxy S2 never had problems like this. This phone is always switching to EDGE. ALWAYS!!! Really causing me to regret my purchase. Also, my "4G" speed test has never gone faster than 3.5-4Mbps down, where my GS2 averaged 9-15Mbps. Only flaw I have had with this phone. I read Verizon users are having the same issues with their GS3. This damn phone annoys the hell outta me and hope the Galaxy Note doesn't have the same radio as this because I can't wait to replace this phone. I love it and how fluid the ui is, but I pay for the 10GB data plan, but this idiotic phone doesn't allow me to use it. And I've had it replaced twice. Gonna replace the SIM later today and see if that helps. So, am I the only one? And I live in an excellent 4G area according to T-Mobile.

This may not help, but could be worth a try.
Open the dialer and enter *#*#4636#*#*
Once u hit the last * it should open up a menu. Select Device Information, scroll down a little and there should be a box to click on. Choose WCDMA Only and see if you can get onto 4G now. If you can get 4G, you can go back and choose WCDMA preffered and see if it acts ok on this setting.
Worth a try at least. Good luck!
And have you called tmobile to see if they are having problems with any towers in your area?

I'm having some similar issues. I can get 4g indoors, but seems to switch around without even moving the phone. I'm wondering if it's a "feature" of the SGS3. Uses less battery to hold EDGE/3g and then when it detects data transfer, switches to 4g... I dunno.
That being said, you can try installing the new OTA which has a new radio. Or if your rooted etc, flash the radio zip Wild put up. I've noticed some improvements with signal strength, but it still seems to swap based on what I'm doing.
Anybody more knowledgeable have any info on this "smart data management"?

The phone will only stay at 4G during data transfers, while idle it'll drop back to 3G. I don't think it should be dropping to edge/2G though.
Did you try the method I mentioned in my other post?

Yes I did and thank you for bringing that to attention , I don't know how I let that slip my mind, I used that setting to fix my last two Samsung phones, Nexus S and GS2. They both would do this just not as bad as the GS3, now the phone holds its 4G/3G much better with WCDMA only turned on. Now I have zero gripes about this phone.
Anyone know what the difference is between HSPA:10 and HSPA+15? Is the latter the HSPA42 T-Mobile advertises?

hold the phone upside down. works wonders i swear lol. especially when you're trying to download something.

Hows the radios working for ya??????

Ok, ready to pull the trigger on a Note 2 but having the ET4G and the issues with reception, Im a little hesitant on Sammy phones now.. I love my Epic T but low up and download speeds kill me. Im missing calls and its not showing up in my call log and texts messages too. I have friends who have the GS3 and some love it and some hate it. Two friends can sit side by side with their SG3 and have totally different reception, I dont get it. I hear the radio and antenna are the same from the GS3 but wondering if the size of the antenna in the Note 2 has changed and if so, is that change enough to help reception issues?
Any input from those who just got one would be greatly appreciated.

I haven't seen lte, but 3g is just as good as you can get on Sprint

I too have the epic touch, a d then the s3.
Although I cannot comment on note 2,because I don't have it yet, the s3's radio is much better than epic touch.
Instant gps lock and no LOS

I too have the E4G and have just been patiently waiting....I almost jumped on the SIII, but thought I would wait. I think GN2 is what I have been waiting for.
The missed calls (never ringing), daily lock ups and reboots are driving me crazy!

I picked mine up this morning, I'm very happy with reception so far, seeing a lot of improvement over my old epic 4g, and the download speeds seem a tad inproved in my commonly trodden areas

I cannot hold a steady 3g data connection. Network mode is set to cdma/lte/evdo and it keep bouncing on and off for 3g. just came from the Evo lte and that phone at the same spot can hold a 3g eHDRP or Evdo just fine. Going to see if sprint can reprovision this phone for me. If this is a normal thing with samsung phone then I have no choice but to return it.

Update:
Phone is now connecting better after switiching perferred roaming from automatic to sprint only. All my previous phone have no problem when set to automatic roaming. Well at least now my data is not dropping like it was. My real test by putting it on sprint only (home on samsung's phone) is to see if it will connect to LTE where's LTE is available. I will find out after work when I'm on my way home since I get no LTE connection here at work.

Anyone coming from the galaxy s3 miss the simultaneous voice and data? I can't believe this phone can't do it unless connected to lte.

How is the wifi? The S3 was weak on stock rom, then improved with AOSP roms.

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 don't get Hspa+ connection everywhere.

I have a Note II Factory unlocked international edition. I also have a $30 Prepaid plan from T-Mobile which is supposed to give me 4G speeds. I dont get them everywhere. At my house i get the 4G speed however when i go to my school which is a mile away. I only get Edge Connection and sometimes out of the blue i get 4G speed back again. Whats wrong with my phone not gewtting those speeds everywhere? its really annoying

My guess is their 4G isn't rolled out wherever your school is.
Or it could be the signal being blocked by all the walls and **** in your school.
It's not a problem with your phone, it's the network itself.

I just got my 7100 unlocked as well and I am on the same plan you are on (its a great deal right?). I have the same problem, I'm stuck on EDGE at home (I'm on wi-fi so its not a big deal) but when I am at work my phone goes crazy. It will switch between H+, H, 3g and EDGE all day long. It will have seizures. The crazy thing is, work is about 10 away from my house so....???
I've been trying to unlock the 1700 band but it may not be possible on the GT-7100. when hitting *#7284#. You're supposed to go into the "Qualcomm usb settings" but that option does not exist on my phone. Anywhere. Its just not there. So I'm stuck.
I know Tmobile is in the process of refarming their network to 1900, but I have no idea when they are going to complete that project. Anyone know?
It may turn out that we'll have to either put up with the EDGE speeds or go with Straight Talk...

Pretty much what the guy beneath you has said. I not every provider guarantees that you will get the same speed everywhere. Not even to mention that tmobile is the only major provider in europe with very very bad coverage.

Yes exactly the problem i am facing. its very frustrating. My phone switches with all day long it mostly stays on Edge though.

This has nothing to do with your phone. Tmobile USA has not rolled out the compatible 3G frequency yet.
