Atrocious 3G speed (1/10 of what my other phone does) - Sprint Samsung Galaxy S III

Having really tough time with my SGIII. After rooting stock ROM and even after update to the latest JB leak from Sprint together with radio updates I am still getting really atrocious 3G speeds.
I am usually getting 50K both ways at best in Boston of all places. Any tips how I should troubleshoot?

Well... that would be easiest thing to say, except that I am getting 600K both ways on my other HTC Sprint phone.

Is your s3 set to cdma only or lte/cdma
I have not tested it on the s3 but I caught a bug on the evo lte where it was connecting to the new enhanced 3g (not actIve yet)
On the evo it would only connect properly if on cdma only.
You may need the app "network" to further mess with it

Sprint Nexus... 3g keeps dropping

It's happening a lot and massively annoying. Anyone else having this problem?

I had Sprint for 3 years...and I always had that problem, especially with newer phones (my last one was the Evo 3D). Sprint is supposedly upgrading their networks, but I just couldn't hold out anymore.
I don't think your problem is just on your Nexus. It's just Sprint's network .

What does LTE have to do with 3G?

Quite a bit.
Sprint isn't just rolling out LTE. LTE users are on a different network, or will be in the near future, called eHRPD. When it goes down, 3G goes away. It doesn't matter if LTE is in your area or not. Non LTE devices will not be affected by eHRPD outages.
This is not an optional thing. eHRPD is required for more seamless switching and will be used by any CDMA/LTE device. Sprint may have not rolled it out yet, but they will. Chances are, they already have. In the event you don't believe me, take a look at the apn list from the latest FD02 release:
http://dl.dropbox.com/u/2056318/apns-conf.xml
Lots of eHRPD entries in there.
I am not saying this is the cause of your issues, but it is a pain on Verizon, and causes similar issues for us.

[Q] - T989 on ATT network

Everything seems to work relatively well with my current unlocked device on ATT. Only problem is data seems kind of patchy (speedtests show it just spiking and dropping like mad, have to hit retry frequently when loading pages or surfing the app store, etc). I am using the ATT APN settings based around the wap.cingular stuff that seems to be the most common. I average around 1mb speeds so my question is would I benefit from finding a different radio for this setup? If so which one should I try?
Device is running the Darkside venom ICS build. Thanks.

I plan on going to a straighttalk sim. Which would be off att (that's the sim I want) and I'm going to keep the ice cream sandwich kernel on it ulve1 I believe it is. I would NOT flash an att radio. I believe that would brick it.

False, you can interchange between SR and herc radios kernels and roms. Just don't odin anything.
Btw to op. Sell your herc and buy a SR for cheaper + using LTE = profitx2

I didn't think the ST plans supported LTE, so SR on ST isn't any benefit over the T989?

OK, why do folks have an interest in flashing skyrocket stuff onto the T989? Just get a carrier unlock from TMO, get an ATT or ST ATT sim, and pop it into the T989, talk away. What am I missing? What does the SR have that the T989 doesn't?

Brick the device, they're interchangeable. Herc does not ignore lte. They don't even pick it up.

For faster data and stronger signal you want an att radio which is design to optimize those bands.
SR has LTE. other than that they're identical

Anyone got any experience / data with this? The T989 seems to work just fine on ATT with stock radio, doesn't seem to need an SR radio. I thought the bands were identical.

its ymmv, the stock radio can pick up H+ on AT&T but for users who have slow data, flashing AT&T radios helps. Unless you're just trying to prove me wrong or something.

Trying to find some data. Something like "on att with tmo radio I get 2 MbS download, but same phone on att with att radio I get 4mbs".
I know that different combinations of radios and roms can improve reception in some areas.
I also haven't seen anything that indicates the MAGNITUDE of the difference.
I get that sometimes, maybe, if you're having trouble with your current reception, you might be able to get better reception if you flash some other radio. (from your current carrier or a different carrier)
BUT some folks think that they should almost routinely flash their T989 to an att radio if they want to use it on ATT. I haven't seen it help at all on my phone.
So my question is two fold, what is the MAGNITUDE of the difference, and, how OFTEN does it make a difference. I was hoping someone had some data on that.
Thanks!

ROMS not keeping 4G

I have been flashing for years and i just came over from ATT SG3 where i had no problems flashing and retaining 4g, but now on tmobile every rom i flash all i ever get is 3g and never 4g .. only for a brief second. the reason i came from ATT was the unlimited data.. can someone please assist as i used CM10, AOKP, WICKEDv5, blackjelly..... i cant figured it out. any help would be appreciated.

Hmm i would think Phoenix should have good service. Maybe you should Odin back to stock and start all over. Radio is the only reason i can think of that would affect the speed.

How are you distinguishing what connection you are on? Many roms will show H+ instead of 4g

I'm on stock. Rooted yesterday and download speeds seem slower now. I will do more testing this afternoon.

well on the t-mobile variations the best you can get is H+ and most ROMs show that. other than that, try using a different kernel. that was the problem for me where my data wouldn't even work sometimes.
It looks like op knows the difference between 3g and 4g/H+ he noticed that he only gets 4g for like a second here and there and that's it.

I had a similar problem. What happened with me was one day I went from great 4G (HSPA+) speeds 80ms Ping, 25MB Down, 4MB Up to all of the sudden a 1200ms Ping with 0.05MB Down and NO UPLOAD.
Turns out it was a problem with some towers in my area. Took T-Mobile two weeks to fix everything. Not sure if that is what's happening here but it could be possible.

Also gonna research radios aswell (really really really liked AOKP just didnt like being back on 3g)

My data is horrible recently!

At home my data is usually always 7mbps-15mbps.. This past week it's been horrible at home. At about 40kbps...
At work and everywhere else it's fine, but once I get home it's horrible! Even 2 miles away from my house, it's fine.
I called tmobile and they filed a ticket to look into the tower but could take up to 10 days.
Anyone have any ideas?

Depending on where u live ur tower by ur house can be old and not updated so it slower or it can be a borrowed tower. The one by ur job must be in a city which they update first. For me the new lte modem sucks I went back to the old modem. It is more reliable.

I get horrible speeds as well and always have. I live in in a crowded area....Brooklyn, New York
Also, it's not like I'm underground or hidden from the outside world, I'm sitting right next to a window in a 6 story building. I've honestly had enough of t-mobile.. they always mess up my contract and have such ****ty speeds in my area. Not to mention, they directly lie to you over the phone and barely keep any promises. Oh and New York being one of the biggest cities isn't even one of the LTE cities that was upgraded. Sorry for this rant but I'm just kinda pissed with TMO.
Does anyone know if I can somehow check if my phone is set on the right antenna?

Yes a big difference. I mostly use WiFi tho when out cause I have WiFi hot spots every place by me. But the lte modem is use less by me till lte is around here.
Use the old apn if you're having issues. There's already a thread on this. Search for it.
I have a feeling the new apn is speed limited so when lte fully rolls out the hspa network isn't overloaded. Most people don't notice a difference between 8mbps and 11mbps. Which was my difference. But if your difference is between 3-5mbps and 55kbps then it's probably a tower issue as well.

If you're in a refarmed market just manually select the 1900 band as AWS might be too crowded. I have to do the same when I'm at my house as on AWS I get 500kbps while on 1900 I get no less than 12mbps

I would not mind having 4G even if crappy.
Your Download speeds should always be almost double your Upload speeds, when they're not like in your screen shot usually means there's a glitch in your tower, if it's consistant I would **72786* it, happens to me sometimes when switching roms. It needs to re sync itself with the tower stuff. Just throwin that out there, hope it helps. Also my speeds on 3G have been all over the place because of the tower work going on in my area. One day I get 2.3 mps the next I'm crawling at less than 100 kps. But yes much more enjoy sending Sprint half the $$ Verizon wants!
