[Q] Galaxy S2 slow on mobile broadband - Galaxy S II Q&A, Help & Troubleshooting

I have an HTC HD2 running Cyanogen 7.0.3 2.3.4
I have a Samsung Galaxy S2 running stock 2.3.4 XXKG2 XEU
Both are on T-Mobile UK network, both on free internet tarifs.
Both have the same APN settings.
Both show 'H' as the connection and both have Wifi disabled.
Using speed test I've been testing both.
The HTC HD2 consistantly gets 1.7-1.9 Mbps download and around 0.5Mbps upload.
The Galaxy S2 never gets more than 0.95 Mbps download and 0.35 upload.
Surely there is something not quite right here.
Any advice/input would be appreciated.
Thanks

Type *#*#9900#*#* and disable fast dormancy. Seems to help for some.

Thanks, unfortunately this hasn't helped.

Further testing shows the following:
The faster speed follows the sim card.
So when the other sim is in the GS2, i get 2mbps + down,
In the HD2, the sim from the GS2 gets only 0.94mbps down.
It seems to me like TMobile are artificially capping download speeds on one my accounts.
Very weird, if not illegal.
At least it's nothing to do with the phone.

It's really fast for me. 3,3Mbps.
with T-Mobile(Dutch) i get 1Mbps
with Hi (kpn/Dutch) i get 3,3
But my t-mobile speed is just 1Mbps soon i will faster internet, then i will test again.
in screenshot, the first two tests are Hi and third is T-Mobile. all tested at the same place.

I too have this problem.
Any updates?

[Q] Axura 2.2.5.7 3g issue

Ok so i just flashed auxora and now ontop I have an h symbol instead of 3g. I did some research and from what I've read the h should be faster then 3g correct but quite the contrary my data speeds have dropped drasticly anyone know how I might fix this?
Some roms show an H and some a 3g. There isn't any difference. The only thing that can change your data speed is using a different modem build.
So then what should I do to regain my old data speeds?
My download speeds on the Speedtest app vary greatly depending on time of day, how strong my signal is and network traffic. If you're hitting anywhere above 3 or 4 mbps that's about as good as can be expected. The speeds that T-Mo promise are theoretical. Auxura has the latest modem build (I think it's JL5) but if you want to try some other ones look here http://forum.xda-developers.com/showthread.php?t=868774

It's not an issue.. The 3G icon was just changed to H.
Im getting a .11 mbps now as compared to the 2mbps I was getting before so im open to any sugestions.

You can try a different modem, but that low seems like you were throttled to me.
Log into your account at tmobile.com and check to see if you went over 5gig of data.

That sounds pretty likley I was doing some heavy downloading over tether. If that is my issue when might my speed be restored if at all?
This might be a stupid question, but you're not using your phone as a mobile ap or tethering with your computer right now are you?
Sounds like what you need it the handy throttle free fix from Master's web site
his new site is http://devsforandroid.com/ipb/

Here's the think tank thread on throttling - Link
Second post shows how to change your APN to get service back until next billing cycle resets it. Then you switch back to your regular APN.

Oh sorry that helps but in a bad way. I don't know how to get out from under Simple mobile throttling, only t-mo.
Maybe search for Simple mobile APNs like we did for t-mobile and try them to see what works. We found t-mo's on Wiki.

Yeah I just noticed that thread said it only worked for t-mobile and bell. The odd thing is ive only got a 3.2gb data usage racked up on my account so that shouldnt be enough to get capped should it?

It just depends on your carrier...

Exactly.
My 5g usage statement was based on the level which t-mo throttles us.
I suggest calling your carrier and checking what they throttle at.

4g Data Speed Issue

Please delete this thread.
Sorry,my bad. As suggested - his wifi was on.Thanks for the APN settings suggestion. In general Atrix's 3g/4g data is faster though.
You might want to try the suggestion in this site.

I tried it but was to no avail since I can't remove the stock APNs baked into the stock rom.

My new galaxy s2 is geeting 3-5 mbps, whereas my friends atrix at the same location is getting 14 mbps. And, i am never able to go above 5 Mbps no matter where i am - that doesn't look like 4G to me. Is there some issue with galaxy s2's 4G ? anybody else having this problem ? thnx

If I'm not mistaken, we don't have 4g on the S2. It's only HSPA+.

Actually, the GS2 should be faster on the same network. The Atrix has a 14mb modem, while the GS2 is 21.

In most places, AT&T '4G' is about the same speed as 3G. In rare locations you DO see real HSPA+ speeds, they are mostly < 10mbps. I don't know about Atrix, but I suspect AT&T didn't have any 21mbps towers around, only 14mbps towers. And those are theoretical speeds, not real world speeds.
In my house, my 4G speed is about 600kbps down and 100kbps up.

I don't believe it. He had probably his Wifi on. 14 mbps never. I had an Atrix and I get with both phones the same speeds.

PLEASE HELP slow internet!!!

Hi guys I recently have my phone getting very slow speeds, It's a Galaxy S 4G and the top speed is 0.12 Mbps, it doesn't matter which server I use to test is always the same thing I am on simple mobile and my data plan is still functioning well, like yesterday speeds were normal, like 5.00mbps or 8mbps but after that. It just slowed down and it doesn't get back up!, What would it be?.My phone is brand new and has been working like a champ for weeks. when I use wifi is really fast but with the cellular data I have this issue.
Thanks

Maybe they throttled you because you went over your limit like the person above said.
You could always call your carrier and ask them.

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 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.

no
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?

300 - 600 kbps download speed !! PLS HELP !!

Hi all,
I try to post a reply on thread "Benefits of International Samsung Galaxy S3 for US (AT&T) users" regarding my issue, but the thread is just too congested so couldn't really get anyone to help me.
I just got the international s3 so excited !!!
I am on at&t prepaid plan unlimited everything...here is the problem tho.
I've tried speed test in san mates, hayward, and san pablo area and I'm only getting 300 - 600 kbps download speed o_0 !!!!
when i am sitting in a car, NOT MOVING AT ALL, data would floats from 3g, hspa, hspa+, or just disconnect every min or so......very unstable.
can anyone pls help me ?? i love the phone and this is the only thing bothering me, all i want is average 1-5mbps download speed
HELP ME LOVE THIS PHONE EVEN MORE PLS !! lol
thanks in advance !!

I am going through this as well......and the only answer that even remotely helps is using different modems....i was at 200-300kbps ALL the time.
i started flashing modems and found that got up to around 3-4 mbps on a good run but thats still high for me. its the main reason i am thinking of getting the US varient.
i was expecting to see at least a CONSISTANT 4-6 Mbps and i am struggling to keep a strong 2-3 and it makes surfing and downloading apps and files a drag.
if anyone has any other thoughts i would love to try them out.

Also, another thing i was thinking is that would it be because i am on prepaid plan ? it shouldn't have anything to do with that right ? its all non smartphone data service for prepaid or postpaid account..... i think..... soooo confused

If its anything like Tmobile, the pay as you go plans lack roaming. So your signal will suffer. My buddy found this out after picking up a pay as you go plan. Call the network and ask if they have roaming on your plan. Then call a few more times to get a general consensus lol.
