[Q] HDSPA Speed or Not

hey guys first thread. be gentle lol
by typing *#*#INFO#*#*
the testing utility comes up and im able to change some setting
by hitting MENU/SELECT RADIO BAND you could change this band b/c the phone is GSM/UMTS i guess if you were in another country you might get service.
THIS ARE THE BANDS
Automatic
EURO band
USA band
JAPAN band
AUS band
AUS2 band
well the reason of the post is b/c i change the prefered network type from WCDMA preferred to GSM/CDMA auto (PRL) and i have seen better speedtest before i was getting 1.2mbps D and .60mbps U now check out the speedtest. take a look at the images and plis if any of you could test it out and see if you get better speedtest please post thanks just to get some input.
now im connected to epc.tmobile.com i know there's another server like voicestream or somehting i can't remember right now. thanks

this is a better img of the speedtest. done thru the website.

Virtually any change you noticed was a placebo effect. Changing the preferred connection type or bands is not going to increase speed, neither will changing the apn.
I've tinkered with all aforementioned settings before and never saw anything change. What matters if where you're located and what tower you're on. Its a good chance that when you switched the connection method that you connected to a different tower with better backhaul which would merit the change you saw. Again, all location based.

If you really changed the phone to only use GSM, then it wouldn't have got anywhere near 1 Mbit/sec, because the fastest GSM/EDGE will do is around 0.38 Mbit/sec.
So I suspect that software isn't doing a lot.
Also, even if it is showing stuff about bands for Europe and the US, that stuff is set in hardware and you can't just change it via a menu. i.e. if you've got a European Desire Z then it's not going to work on T-Mobile's US network because it just doesn't have the right antenna.

Don't use mobilespeedtest.net. I think the android browser caches the file or whatever its downloading. I say this because I've gotten almost 31 mbps before on it.

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.

Disabling LTE (saves battery?) Easy on GS4

Not sure if this was posted already but looking through the menus I found how to easily disable LTE. It's not around here and I read having it enabled eats battery. My HSPA speeds are 5-10 megs which is more than enough for what I do.
Anyway:
Settings
Connections Tab
More Networks
Mobile Networks
Network Mode
Choose GSM/WCDMA (auto connect). 2nd one from the top.
It seems this device sucks up battery at twice the rate of my former Note 2. Maybe this will help.

It just says 4G when you have LTE on the Galaxy S4. At least for Sprint anyway. I use Cyanogenmod so mine does say LTE. For AT&T I know for a fact that it says LTE on the top right of the 4G icon.

[Q] Cell phone repeater

Acording to
T-MOBILE
Get more from life.®
SYSTEM: 1900 MHz, 1.7/2.1 GHz
TECHNOLOGY: GSM / GPRS, EDGE, UMTS, LTE Planned
THe area i am in uses all three, 1900 1700 2100 mhz bands, so if i get a 1900 MHz cell phone repeater, that will improve my 3g/HSPA+ signal?
Not sure what frequencies are used for T-Mobile HSPA(+) services anymore with all the refarming and such going on. Thanks guys

where do you plan on getting yours from? would rather have a repeater then stay on touchwiz just for wifi calling

In for the info. I need a little bump in signal at the house.

Have you tried calling T-Mobile about that? I'm sure that if you talked to someone deep enough in the customer service/technical support they would be able to give you an answer.

EBay. They have a huge selection and from what I've found online the Dr cell brands are very good and last forever. They range from about 140 and up. Which sucks lol.

so far from what I'm discovering, if your area has the refarmed towers to support the HSPA+ 1900 MHz frequency, then a 1900 repeater will work. Otherwise, you will need an AWS repeater. I'm thinking of getting the 1900 one. Every website I've found states that's supported in my area. Can always return it.

And lte repeaters are very pricey! Lol

Oh I understand, but for a $140+ investment, I'd rather take the time and make sure it's right than be all like "Well... that sucks." It's funny you posted this because I was thinking about the whole repeater thing the other day and after seeing the prices I decided to go ahead and stop researching lol.

Very true lol. But what i ended up doing was finding one of those Cel-Fi signal boosters from T-Mobile themselves that boosts the AWS frequency band (which i know is in my area) for 90 bucks BNIB (just opened) so hopefully that helps!
But i have done some more research, and after many articles of online posts, so long as your area has the refarmed towers to put out HSPA(+) on the 1900 MHz spectrum then any GSM 1900 MHz repeater will work. Just make sure its GSM and NOT CDMA. If you don't have the 1900 MHz band in your area. Then a GSM 1700 MHz repeater will work (thats pretty much what the Cel-Fi is) Can't wait! No more dead spots!

You can get them for no cost from tmobile if you are on a classic plan. Not sure about other plans. They are out of stock right now. I am on the wait list.

You have to meet certain specifications. Which I don't think I meet. Plus according to their website, they are no longer available

Just an update. Got my T-Mobile Cel-Fi repeater just now. And it's working ^-^
I now get 4g in my basement! Just wish the output power of the broadcast was stronger. Barely reaches my room.

Will the m919 get 3G in Brazil?

This is Brazil´s top four networks frequencies;
1-Vivo
GSM-900/1800 (GPRS, EDGE)
2100 MHz UMTS, HSDPA, HSPA+
2600 MHz LTE
2-TIM
GSM-900/1800 (GPRS, EDGE)
2100 MHz UMTS, HSDPA,
2600 MHz LTE
3-Claro
GSM-900/1800 (GPRS, EDGE)
2100 MHz UMTS, HSDPA, HSPA+
2600 MHz LTE
4-Oi
GSM-1800 (GPRS, EDGE)
2100 MHz UMTS, HSDPA
2600 MHz LTE
I know LTE won´t work, and from what I remember of Tmo´s 3G our S4 needs two bands to work (1700/2100 ?).
Can I make it work on a single 2100 band?
Or, am I really doomed and stuck with EDGE or worse?
Thanks

Is this a stupid question?

Its just a hard one to answer.. But you definitely won't get LTE, 3G/HSPA will probably be a hit or miss. Its not worth the gamble IMO

Thanks. Unfortunately I already paid to get in. I´m in Brazil now for the world cup. I didn´t want to change my granfathered plan with tmo to get their "unlimited international data", and thinking about it, if I can get 3G with tmo over here then I can get with the local carriers. But what I´m afraid of is that tmo´s free data is only edge as they have a page saying "Standard speeds approx. 128 Kbps (for all countries)". So it wouldn´t do me much good to change the plans anyway.
What I was hoping was that the phone would be capable of using the 2100MHz both ways or that I could flash a radio that would allow the s4 to work that way.
I´ll test the first premise at the store on Wednesday. If anybody knows about the second one, please tell.
Thanks.

Oh I thought you lived in Brazil and was looking to get one.. And yup the standard is 2G unlimited but I think if you pay around $50 you get 5gb of high speed internet, which I guess would be 3g/hspa, don't know about LTE
Edit: there is a possibility 3g/h will work, all T-Mobile phones should support that band so hopefully it'll be able to pick it up

Well, well, well... unless my phone is reporting wrong or their hspa+ is real fast here, i think I'm getting LTE in Brasil with a US phone.
As soon as I put the SIM card in, a LTE 4G sign appeared on thr top right. I couldn't believe it so I did a test with that speedtest app (oogla?) and got around 15Mbps download and around 3Mbps upload. The bad part is that the app used 50MB for test, which cost me around a buck just for the test. But it made me so happy that I think it was worth it.
So what do you think of that? Is this a real fast 3g+, or does this phone have the LTE band (4?) they use here?
There are stories about it having all the bands, and maybe the limited bands story is just FUD.
Would their sim card be able to make changes to the phone? Cause I found a new app with the carrier name installed after I put the sim in, and my phone wasn't set to allow installation from 'unknown sources'.

that's surprising but yes it does have band 4 LTE, good to know it works!! didn't think 2600mhz would be band 4, or it may have larger support for LTE bands, couldn't say for sure since I never go out of the country to test on my own
Edit: and what do you mean making changes to the phone?
