How to improve 3G?

Hey guys I have had my Evo for awhile now and Sprints network has great coverage BUT the 3g seems abysmally slow. For instance, I can rarely stream videos without it buffering - youtube videos on regular quality mind you. If I stand still in a place with good signal I will be fine but if I'm moving etc it is slow. I get around 100KB/s during daytime where I live and 130KB/s night time which is great but luckily I also get full signal where I am. On the go, it sucks.
Are there any ways to increase 3g speeds or is it purely network related?

Welcome to sprints idea of 3g
God's honst truth man... if thats all you get... thats all you are going to get because sprints 3g network is the worst i have ever seen. Bar none. Even little us cellular has better coverage and twice the data speeds as sprint does here in iowa.
There is no possible way for the phine or any hack to it to speed up sprints crap network.
My advise to you is to cqll sprint and plead your case, that you paid for 3g and are getting 1x rtt speeds 24/7 and politely demand a credit to your account like i do every month.
And then call back about 5 minutes later and ask to speak to the retention center because you want to cancel your service because you arpe not getting service you are paying for.
Then tell the retention persion you were thinking of getting the Airave but cant afford it and see if they will give it to you free on the basis of poor service and they typically will.
I did, and got one for when i am at work and the boss wont let me use it because it uses works internet for voice and data.

Figures... Should have went with ATT or Verizon.

I know in the old days of 3g internet hacks Sanyo phones had a data cap screen that was accessible via ##040793##. From there you could change the data rate, 144K/230K. Not sure if we have the same here but phone codes may be a place to start.

Mmmmhmmm. Just be glad you don't have the epic and are capped at 150kbps up.
I think sprint has finally gotten 2 good phones and 4g, so now they think they're the top dog and can do whatever they damn well please...it's like a cycle with them. Bad service>>>loose all of their customers>>>cheap, semi-good service>>>get customers back>>>become assholes again>>>loose their customers...

lol, good luck getting a decent phone on att or verizon. Let alone coverage. Oh and dont forget about the data caps on the phones, 100mb right? or was it 200mb?

Well Verizon has amazing android phones for one. There is a data cap for ATT which is true but no cap for Verizon. You know now that I think about it I might do the force roam hack on my Evo and see if if I get better 3g speeds.

I have no idea what any if you are talking about, I get better 3g speeds on Sprint then I ever did with any other carrier I've had.

I wish I could get speeds that fast consistently. Actually what you are getting is right about on par for 3g. That's prob the avg speed one would expect to get. There are higher areas and lower areas depending on a lot of things. A 100KB connection is nothing to complain about. I've personally never had a connection over 150 KB.
Sent from your mom's phone.

Not sure if its sprint or my phone but I can't break 40kbs down on anything and 3g cuts out all the time. Crappy....

The first thing I would do to verify your 3g speeds is to unroot your phone, and make sure you are running the latest .93 hboot release and sprint ota release. If your phone is already in this state (un rooted and latest hboot) then ignore me.
You should also look into unrevoked forever if you haven't already...it runs off the current hboot, and I've noticed that something about that hboot does help 3g speeds on some rooted phones if you go that route.
I've done a ton of research and practical testing on this subject and I can say without a doubt that the evo's current rooting methods DO have a negative impact on some 3g phones in some areas. And I'm not talking about 100 or 200 kbps here or there. In the same house, same phone, 1 rooted and 1 not. That was the ONLY difference. The rooted phone got 7 kbps. The stock got 1800kbps. I swapped phone setups so that the rooted one was now unrooted and vice versa. That time the rooted one got 47kbps and unrooted was 1681 kbps...in other words the problem followed the rooting process, and not the phone. I've done dozens of tests like this and others in various areas within the surrounding wilmington delaware area.
I have access to 3 rooted evos, 1 evo that is always stock, as well as a samsung moment. The 4 evos are all rev 3 nova. I also did similar tests on the hero with the same sorts of results. Feel free to pm me or post here with any questions.
EDIT: the kbps numbers I listed were for download speeds. Upload speeds on both rooted and unrooted, regardless of build or boot version, were consistent at around 600 -700 kbps during almost all of my testing.
EDIT2: I forgot to say - this problem also happened to me when I changed recoveries from clockwork to AmonRA. So it's not JUST the rooting process that can cause this, but several low-level engineering commands, such as flashing a kernel, upgrading a ROM, etc.

That's pretty crappy, I get full 3g pretty much everywhere around St. Louis until I get out to the country. And pretty good 4g around town. My 3g is about 1.5mb down. 4g is 5 to 7mb down.
Sent from my PC36100 using Tapatalk

Flash the PRL to connect to Verizon's towers. I get 1.2 mb/s even see 2mb/s occasionally. Of course ping times are raised.

It's pretty hit or miss here, one day I will get 50-150k down and the next it will be +1meg. Next time it get drops below 500 you can bet I will be talking to somebody about it though, their advertised 3G speed is 600kb - 1.5mb.
100kb is ridiculous

I get anywhere between 500-1mb down 100-200kb up. My 4G easily does between 2-6mb down and 1mb up. People just love to complain. You didn't realize this within your 30 day trial? If so, why didn't you switch carriers?

What should the prl be right now ? And how are you guys testing the speeds? Nvr done it

You live in an area with poor coverage or your phone has a faulty radio.
I get good signal and up/Downs on 3g. If I nandriod away from cm6, I can get 6-7mb down and 1mb up with 4g in San leandro CA.

Speedtest... its in the market.

I think it is my radio. I was getting fine speeds up until 3 days ago when I noticed severe loading lag in my tethered apps. I get decent pings ~ 200-300ms which is not too out of the ordinary. I did a speed test other day and it was 50KB/s down and 70KB/s up. I figured it was just a faulty day but it has gone on far too long now. This is with 5/5 bars too... Just gotta wait for my new Evo to come in. Seems like every hardware ****up is happening at once.

LOS finally hit me... and hit HARD!

I was at the Brewer's game last night, and the loss of service was horrible. I literally rebooted 18 (I counted) times during the game, that was just to get my missed text messages.
Scary thing is that I had nearly full bars showing for the cellular signal, but the 3G was terrible. Every time the 3G dropped too low, it took both the 3G and cellular service with it, and it never came back. At one point, I rebooted 5 times in a row, and still had no service (no data, and texting/calling would not work), even though I was showing nearly full reception.
I couldn't keep the radios working long enough to even successfully use Roam control. By the time I was able to switch to roaming (on Cellular One, apparently), the radios were already crashed, and I still had no service (even though I still had no indication).
About halfway through the game, I finally started getting the triangle notification "You have lost data services be...." Toggling roaming policies and roam guards did nothing to make this go away... Whether I was in forced roam or on Sprint.
I assume that there was a lot of network congestion at a playoff game, but clearly this phone does not handle network congestion well. I never had this problem with the Samsung Moment, and it saddens me to think that that piece of crap does ANYTHING better than the ET!
I wonder if the low data signal somehow creates a cascade of events that tells the phone to shut down the radios?

I never experienced LOS until yesterday and it's hit me 5 times now since. I reverted back to stock kernel for the time being, but I'm afraid it'll happen again since it's even a stock problem (from what I've heard.)

There is a kernel in the dev section to fix LOS. Take a look at lostkernel.

I'm running the stock with root (flashed CWM, then flashed the root .zip).
I forgot to mention that after the game in the parking lot (about 4 blocks from the stadium) a reboot set my phone working perfectly fine again, so I'm thinking its a combination of something Sprint's network tells our phone, and then something in Samsung's kernel goes "Duh...."

That stinks about the phone though :-( I hope it's something that gets resolved, sorry you had to mess with it during the game.

Roam Control periodically does a license check when you start it. If you don't have data, and it decides to check the license, you are SOL.
As for rebooting, it was necessary to reboot because that's the only time I got text messages. We had two sets of two seats, and texting was the only way to communicate with people 3 second away.
Perhaps you should spend some time with kindergartners and take some etiquette lessons. Although they might be too advanced in that area for you to learn much.

Great. Let's see you try to set up meeting places, or exit strategies with people you can't communicate with. Or are you the rude type that would barge into the middle of somebody else's section?
As for Roam Control, it just updated from the market, so its the latest version. Try reading the description.

Sprint's 3G in Milwaukee is not working at all. Sprint offered to let me out of contract free because of the 3G being out since June and still not fixed.
Sent from my SPH-D710 using XDA App

I live in Milwaukee as well and I can vouch for how terrible the 3g is here. I only use about 1 gig a month in data on a light month and about 2 gigs a month on a heavy month. I even tried using my slingplayer as much as I could keeping it on for a few hours at a time for a whole month and I barely used 3 gigs!! When Verizon gets a nice phone with LTE I'm ditching sprint for a network that actually works here. And I don't care about the caps because I don't even use that much to begin with. And if Sprint ends up getting LTE in Milwaukee by 2013 maybe I'll come back...but since sprint has no wimax here...and they won't fix the 3G, I'm guessing Milwaukee will be the very last city to get LTE.....

First off, I've done multiple data resets since I activated the phone last month, and 3G data has not improved one bit.
Second, according to other posts, I obviously am not the only one with a data problem in my city, so posting here helped me with some evidence to go to Sprint and get credit or out of my contract, doesn't it?

The ONLY place I get decent 3G speeds is by the airport. Just did a speed test, and I got 1.3mbs down... Everywhere else in the city, I average somewhere around .15, which is basically 1xRTT speeds.
How did you go about getting the offer to let you out of the contract? Did you have to call multiple times? Honestly, I'm hoping that this phantom update that's supposedly coming this month actually fixes something, but with Samsung/Sprint, I'm not holding my breath.
I go back to my experience with the Moment. Sprint put out several updated, but never managed to fix the data lock problem (which also cut out voice service, which is eerily similar to what's happening here). It took the devs over at SDX to fix the problem by porting Froyo over from the Acclaim (or maybe it was the Intercept... I forget).
Bonus information: By the airport there is a 4G tower that's active. I can pull 3mbs at work, and if I go about 6 blocks north, I can pull 11mbs.

Yeah, that's my worry. Sprint doesn't seem to have any logical progression of cities they implement 4G in. Milwaukee is a Top 20 city (by population), so you'd think they'd be in the first wave. But no, they'd rather put 4G in Milledgville, GA, population 19,000 before a city with 500,000.

3g and 4g speed on sprint - questions

I have a rooted EVO 4G with the stock Rom and I have been experiencing slow speeds lately. I've tried searching the net and have found numerous articles that contradict one another at times. Most pages sujjest to change the prl so I've tried that and have had no luck thus far. I do not want to do the prl hack where I would use verizons towers because ay the moment I do not want to get terminated from Sprint. I just do not like the speeds I've been getting lately. Had anyone had any luck with some type of modification to their phone that has helped speed their data up??
I live in new York city and almost always have 3 to 4 bars of reception. So I don't think that's the problem.I'm attaching 2 screenshots of my speed results. Obviously the faster one is where I was using 4G. I have tried multiple prl files and the speed is around the same with each. Any help would be greatly appreciated

PRL has nothing to do with sprint. The prl update just updates the towers you connect to when roaming.

There is no mod you can do, Sprint's speeds just suck right now. I personally got the evo in June of last year on launch day. For a few months, I got perfectly normal speeds, around 2mbps. In November of last year, my speeds went to about 100kbps, and I haven't gotten above 150kbps on sprint's network since then. Nothing you can do about it, Sprint just needs to majorly update their network, and we all know that isnt going to happen anytime soon.

You can try the 3G Turbocharger, it's in the V6 Supercharger thread. I'm pretty sure it just makes some changes to your build.prop to help with your connection.
I honestly didn't see much of a difference using it, but I rarely use 3g. A lot of people claimed that it helped, so it may be worth a shot.
The bottom line is that Sprint's service sucks. With the new influx of heavy data users, there's even more strain on the network. I'm lucky, I still get usable speeds, but some people get just awful speeds. If Sprint doesn't step it up and do something, they're going to lose customers.

What option are you talking about? What modifications are you suggesting to make?

your posted speeds are faster than mine lol

Those speeds are better than my 3g, and I don't even have 4g to compare.
My 3G used to be good until earlier this month. I could sometimes snag 1000kbps but now I pull dismal numbers. It seems that the bad 3g speeds are because of heavy network traffic. When I speedtest at around 1am, my speeds go back up to the 1000kbps range.
I suspect the iPhone 4S had something to do with this, and also the S2 was released fairly recently.

Slow data speeds and spotty service

I've noticed spotty and inconsistent data/service on my phone. Even with full bars I get data speeds like shown in the attachments. When using the phone it will sometimes say I have no data connection and ask me to retry. I retry a few times and it finally loads whatever it is I'm loading. I've also noticed that my phone sometimes gets a little warm while in use. I've tried different modems with the same results and I'm about ready to just take it to the sprint store and get it swapped. Any suggestions on what might fix it? I can confirm that it is something with my phone because I've run side by side speed tests with my friends OG epic and their speeds are normal. Any help would be greatly appreciated.

Thats about what I get too. Its a combo of this phone and Sprints crappy network! My evo got better speeds as well.

I am getting the same thing too. Funny thing is that it just started being this way recently, it wasn't always slow. It is not just the data speeds, I am getting no service in places where I used to get service.
I have been seriously thinking about switching carriers and moving to t-mobile but a little afraid because I have been with sprint forever.
If something don't change by the end of the month, sprint may be losing another customer since the GSIII is on ALL carriers.
I am in Raleigh/Durham NC by the way.

I agree... it didn't feel so bad until I got my ET4G, but I just figured it was a network issue. I'm trying the EL29 modem on my Calks 1.6 now. If anything I'll try going fully stock and see if that helps.

Welcome to the Sprint network

Some people are experiencing network issues in places where Sprint is upgrading to LTE. I don't know how far-reaching the effects are but could possibly have something to do with it.

Yes, I notice the same thing lately with Sprint Wimax, I may have to dumb Sprint later. Sprint data speed gradually slows down from time to time, some area, Sprint shows only 1X, I look at friends' phones with Verizon, ATT and Tmobile, they have very good speed. My brother has Verizon LTE phone, I speedtested at the same location, he got like 17mbps download and upload is about 15mbps, mine is 1X speed. Suck, I gonna say goodbye to Sprint later.

Welcome to the Sprint network with the New iPhone4s d-bags. Seems like things were great till they showed up. Even my Evo got slower.

data
Maybe your phone is stuck in 1x..
What i do is i go into debug (##debug# in dialer) and i go to others, and then i select hdr/1x and i click on evdo mode. Try doing this but you need your msl.
Caution: ive tried it on ics roms and its really weird. Try going on a GB rom and do that. Oh and on EVDO, you wont be able to recieve messages, so when you are done change the setting back to hybrid.

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.

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?

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.

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
