HSPA issues - Galaxy S III Q&A, Help & Troubleshooting

I have a International Galaxy S3 I9300 bought in India and i have come to US and have took a TMobile connection. Now the issue is that , im not getting 3g(h,h+) speeds all the time. I have set my device in Auto(GSM/WCDMA) . I have another guy under same roof using same Tmobile conn (Nexus 4) and he is getting 3g speeds and im not. Its showing as Edge('E') in my phone. I can confirm that the 3G is working at some places near my apartment so its not an activation issue or something. Does it has to do anything with the ROM/kerner . I have been using the Foxhound/Persus combo. Should i change the modem settings?

Try setting the Network Mode setting to WCDMA only (instead of auto). I am on AT&T, but was having same problem in certain areas and this fixed it.

Yes, i tried this, but the network goes blank. I'm sure im covered under a 3G area as the other guy is getting awesome speeds under the same roof. Was it because the other guy got his mobile in US(Nexus 4) and i got the international version that it could not read certain spectrum? Really confused.

Did you compare APN settings with other phone? Somewhere here there are probably APN settings that are optimized for T-Mobile. Or may find them on Google.

My gt-i9300 does the same

I'm on omega v35 and I have tmobile as well. it seems I get this edge all around were I live but then I'll go about a mile in any direction and I'll "all hspap??, 4g, 3g., all" I guess thats because of the towers mabey and the fact that I have the international as well. If any one knows why I would like to know as well.

Network Speeds AT&T

im in houston with my international SGS3...
i have tried 3 modems, and i can seem to get above 1.5mbps downloading EVER, unless on WiFi
what speeds are you guys seeing on average with international note in the US on AT&T

Exynos not compatible with AT&T Network. Only HSPA+ I have the HTC One X Quad core on Straight Talk (AT&T MVNO) and get gravy HSPA+ speeds here in Charlotte
so what your saying is no matter what i will not get any better speeds than 1.5 and lower. i get 3g/4g/h+ on my SGS3 right now. unless there just false indicators in the notification bar so i dont see the incompatibility.
Im still in my "iphone" plan and get about 6mb down

i would take a consistent half of that....lol
i really didnt think it would be this slow. i mean the phone is blazing----but let me try to download an app. or start up netflix on the go, i even see it in web browsing it just seems slow. and my infuse was not LTE and it ran h+ and got the same 5-6 on at&t
I'm averaging around 3.5 down and 1.5 up on at&t in central pa...ps we don't have lte here...yet

There is definitely something going on with the SGS3. Right next to my unbranded SGS2/GT-I9100, I'm getting much lower speeds on the exact same network. I'm talking 7.5Mbps vs 3Mbps on AT&T.
Not sure if the modem's just not optimized for the US AT&T networks (yet).
Thank for the test, i really didnt think this was normal. i hoping to find a modem that works well enough to get me the 3-4 mbps......
right now, all yesterday......i could NEVER even get above 300kbps
i love the phone less this aspect of it right now.

to the OP and anyone experiencing slow network speeds, check you apn settings on the phone make sure you have the ATT phone apn selected (apn name phone) instead of the default Cingular apn...Phone is the HSPA+ apn but on unlocked international phones it defaults to the APN provided by your sim which is the Cingular one...case in point on my nexus i have to always manually input the phone APN after flashing a rom...
also even though 2 phones running on the same network maybe in the same physical location, they may not be connected to the same Cell Site Tower, as such each phone maybe communicating with different towers with varying degrees of network congestion, thereby affecting your speeds...it could also just be the area you're in...as another ATT user with an international s3 has posted screens of him gettin 8mb down

I'm don't think you can switch to the phone APN on the $10/$15 medianet plan... has this changed?
I understand cell towers, but you have to realize you're really reaching with that explanation... especially when I am able to get consistent 6-7.5Mbps ALL DAY on the GT-I9100 when I have not been able to hit 3.5Mbps downloads sitting in my office all morning. I'm talking well over 10 tests at various times throughout the day, SOMETHING is up.
CONFIRMED: phone APN does NOT work on the medianet plan, so let's not muddy the water and confuse the issue at hand.

Well if you can't change the APN..you can either complain to ATT or try another S3...for me when I first got my GNex I got crap slow speeds on HSPA+ till changing the APN...but I am not on a medianet plan..

That's the point, I'm talking about the medianet plan, and getting much faster speeds on a phone sitting right next to it. Repeatable results too.
Again, has nothing to do with APN in this case.

NO, that's not what I'm saying. I'm saying I'm seeing significantly slower speeds than my UK GT-I9100 when running the same exact speed tests at various times during the day. Could just be a modem issue as these phones were launched for the UK region, who knows.
Okay thanks, looking to purchase a galaxy s3 and justifying the savings from the 5gb data vs medianet plan to my wife. BTW what color is yours?

P500 and T-mobile data

This may be a total noob question, but that's because I am indeed a noob when it comes to this. A bit of history about my Optimus One: I got it on the internets and I believe it is for Portugal's Vodafone, as suggested by the default APN. This thing runs the original Android 2.2 and I did not bother to root it.
Recently I got the T-mobile's six months of free data promo (I'm in Boulder, CO) and all I get is a whopping 120 kbps downstream. All settings seem to be according to T-mobile's "official" info. Tech support told me that everything is peachy on their end, but my phone is "not supported" and I need to get a "supported" one from T-mobile.
Is this the case, or is it merely a matter of installing a ROM/app that unlocks the proper band for data? I am not really afraid to play with this phone, because in the very worst case I could actually get one from T-mobile. Also, because I have no contract, I could move to another provider, so there's some freedom. Thoughts?

You have 3G data enabled? 3G available in your area? The tech support "advise" is complete crap.

3G enabled on the phone? I don't see anything beyond "enable data" and when it's enabled, there's an "E" next to the sign at the top of the screen.
Yeah, 3G does cover this area and the t-mobile rep claims the setup on their end is right.

Well, E is EDGE (which is just a bit faster GPRS), no wonder it is slow. You need H (as in HSDPA). If there's no way to enable 3G on Froyo (strongly suspect you just need to look harder), then upgrade the ROM!

Well, I see nothing about 3G under mobile network settings... network mode 'GSM/WCDMA auto', tried with and without data roaming enabled, APN set up as the t-mobile website suggests... Am I looking in the wrong place?
Also, could this be related? Which I guess could effectively mean the tech support was right...

1/ HSDPA definitely worked for me with Froyo. (No, I will not flash such junk again to verify, being on ICS now)
2/ There has been a GB update available for over a year. Why do not you upgrade?
3/ Normal european P500 specs are
GSM/GPRS/EDGE: 850/900/1800/1900 MHz
UMTS/HSPA: 900/2100 MHz
Sorry, no idea what T-Mobile uses somewhere in CO. US T-Mobile has been selling this very same phone branded as LG Optimus T.

You dont need to flash any ROM if only thing you want is high speed internet..
First call the customer care and ask whether its a 3G pack that you got or normal
GPRS/EDGE. If its EDGE then its the maximum speed you going to get..
if its a 3G pack.. go to settings and select ONLY WCDMA and ask them to send you
3G settings too. Well i Activated 3G and got APN settings automatically.
Do ask customer care if your area has 3G coverage!!
T-Mobile does not support the European 3G bands in your area. In certain metropolitan areas you will get a 2100MHZ signal on T-Mobile, but most of the time you will be getting incompatible frequencies hence the need to use EDGE (2G aka the E which is much slower than 3G).

Thanks guys.
I think several responses are due to the fact that I did not make my location clear: I am in the US and the phone was originally for a European provider. I did confirm with the customer service that I am supposed to have a 3G/4G connection.

I'll have a chance to test it in Chicago next week.
I suppose the frequency incompatibility is at the hardware level and changing the ROM wouldn't help. Can you confirm this? I am ready to flash cyanogenmod (or whatever you guys can suggest), but if this is a hardware issue, there's no point, is there?

Yes, you can't just change frequencies by just flashing another ROM. It is hardware related

[q] my new gs2

hey guys I got an gs2 the other day but to notice its not picking up my network 's 3g , but my old gs2 picks it up my newly gs2 only picks up edge, is it cause it came from a different country or something? is the band maybe different. and is there anyway to get it to picks up the 3g

did you check the network mode (GSM / WCDMA) settings?
yes that's already checked
So...with only WCDMA you get no network right?
I guess you could flash another Modem, can't hurt.

Not enough details for anyone to help yet.
Are you using it with ATT or is it unlocked and you are using another carrier and/or in another country?
Are there issues with signal strength with other phones on that network in your area?
For 3G/4G, have you checked the network settings to make sure it's not set to GSM only?
If it is set for HSPA/LTE, do you have the correct APNs?
Have you modified the software and/or changed the modem?
Has the phone ever been dropped, opened/worked on, and/or had liquid damage?
What update are you on?

The phone supports Jordan's network frequency of 2100, but it wouldn't surprise me if it is locked out of doing so without changing something in the Hidden Menu. I don't have a way to confirm that, but it's something they do with many of their phones. If you don't even have the option to switch to different network types, then that's why - probably only ATT's main network frequencies are enabled by default.

Sprint/T-Mobile LgV60

Is anyone else whos on sprint/TMobile having issues where the phone cant decide wether to connect to a sprint or TMobile tower? When im at my home i have a very weak TMobile 600mhz signal and a strong sprint band 41 signal due to the magic box. I also can pick up the band 25 signal the box uses and my phone refuses to just use the stronger faster sprint signal. It absolutely insists on using the TMobile signal. Is anyone having similar issues? Even on wifi its causing network interruptions so i have to reload a page several times to make it use the wifi.

Mine jumps a lot but never connects to the magic box. I don't think it's enabled for B41? I have a Pixel 3XL that I activate (and deactivate my V60) when I'm at my camper which is where my MB lives.

Mine works with Band 41. Its a big one in the nearby city. It works with all sprint and TMobile bands. Its just prioritizing TMobile bands over sprint ones regardless of signal quality

I have no idea of this is related but.. I'm on T-Mobile, with T-Mobile home internet as well, and for the last several days my phone is having issues connecting and the home WiFi is doing the same thing. I'm in a rural area so my signal is weak, but it's been fluctuating WILDLY since the merger and sometimes it does seem like my phone is struggling trying to decide what to connect to. There's definitely something going on with the network at least in my area for the last 2 weeks for sure

Sounds like this will be happening until the transition is done/5G is more widespread. These are TMobile models. When mine was first turned on at the store it had the T-Mobile splash screen. The ability to access sprint towers was added via software update post merger. I figure once the 600mhz band is fully rolled out the issue will go away as a result of the signal being strong enough.
