I know every epic is different. I know your modem deals with 3g speeds and 4g. I know we have different towers. I know this. But what i want to know is some of your opinions about your personal experiences with the new modem. How is going for you? Was it worth the "upgrade" from ei22? Experiencing any bugs? Performance?...I would have to go thru a lot to flash it so b4i go thru it all, i would just like to know what you guys think. Thanks!
On an Airave 2 I get about half the data speeds as I did on EI22 and EC05. YMMV

I was not able to connect to 4g at all after flashin to EL30. Anyone else experience this?
I have wifi jumping on and off w el30 update. Not super happy. Never did it on anything other than el30. Yuck. I used Odin. Anyone else getting same thing?
Edit: after flashing different el30 rom's last night and having wifi issues w all of them I chose to Odin el30 today and much to my surprise...wifi problems. I reset my router and everything is fine. Very odd as no other Tom caused this issue and other phones and devices connected fine. Crisis averted haha
I had that with signal and 4G, my wifi was fine.

WHAT???
Since I've made the jump to EL30, my 3g speed has been as good as 4g speeds(had I had it in my area), GPS is pretty good(alot better with GPS fix), With GPS Status, I got 10/11 locked Sats inside my house. 6/7 before installing that. battery life...considering i'm using the 1800mah from the touch, is great. Haven't tried with the 1500mah cause it's almost 2yrs old.
On another note, there was a issue that I'd like to point out. I checked my Market apps and found 2 weirdly named apps that's been renamed as 2 of the systems' apps...Video player and system updates. Which had a review of 1.5 because they were consider as spyware by 100% of reviewers. I had to use TB to first freeze, then uninstall them both to get them removed from my Market apps list. No other way would even work.
Other than that, Stock, Rooted, Doedexed EL30 Rom is great for me. As they say, YMMV.
I get higher TWS percentage with EL30 than with EI22 modem. I'm averaging between 5-15% TWS on EL30, whereas on EI22 I would average 1-5%.
There are many times when I wake the phone up and i'm at 0 bars, then it takes a good 20-45seconds to get between 1 and full bars. (Depending on my location at the time.)
Hmm...interesting..i just posted about this in another thread. i bricked my phone...brought it back..im rooted...and actually still on stock el30..the battery life is actually good...the signal is better..and im enjoying it actually...for the time being..thanks for everyones input...gotta love our community!!
Did not see any previous treads that mentioned this condition.
Its been going on for a while since I started flashing ICS. Three different builds by different Dev's and I get the same results Slow download speed and CRAZY fast upload speeds,with good 3G and 4G connections, I live in a metro area with tons of anteneas and towers around me. Using control Epic (Wifey's stock Epic) on same networks while running speedtest at the same time on both Epics.
I still get data, but its butt slow while stock Epic just wizzes along with Youtube, play store, Emails, whatever it is concerning data. This time around WiFi is not affected that works fine on both phones, streaming, downloading, both are equal. On on build i had reverse WiFi speeds also, but not this time.
Anyone come across this BUG??? Currently running Calk's E4GT 2 v1.2, FC18 Modem, ICS 4 ICS theme. Great looks fast Rom everything works, (kinda)
Rouge recovery.
When I revert back to stock/rooted EL29 all is normal again. Fast D/L - slow U/L.
Pp.:confused
PS. Second time around with this question.
Common where are those android brains, is this stumping you guys!!!
Give it your best shot, I'll consider any idea or suggestion. Don't just look , post.!!
try changing your modem?
Will try fc22 see how that works. maybe reflash rom too.
did it work?
No. Still the same. Luckely I'm around WiFi most of the time. On FC22 modem. Now.

I'm having the same problem. I'm also in a metro area (NYC). Fast data on stock/gingerbread ROMs. Slow data on any ICS roms. and i mean slooooooow.
I've flashed multiple ROMS, kernals and modems, no avail.
I actually get decent speeds in Manhattan (but not stellar) but in Brooklyn (a mere 12 miles away) i get .10 Mb speeds, no exaggeration. I find it hard to believe that someone is going to tell me that Brooklyn won't have the towers i need for decent data.
Wifi works perfectly on both ICS and GB.
We can't be the only two having this problem. I've googled it and searched the forum but I can't find an answer. Could it be that ICS isn't officially out for the e4gt yet so the ROMs are having flakey service?
Please help, anyone.
On a side note thought, the ROMs that I have tried have no other major issues for me. great job to those who developed them!

I had the Evo 4g for about 1.5 years and it was a great phone. It started having problems so I decided to upgrade to the Samsung S2 on Sprint. Ever since I got it I have low signal most everywhere, can't connect to 4g unless I'm out under open sky, and my phone flips to roaming a lot. I have updated everything but still no fix.

A lot of times when I am roaming or have really low bars I can't make or receive calls at all. I seem to remember having similar problems with a Samsung device on T-Mobile. Is the hardware side of Samsung's weaker than HTC? If it was just low signal but I could still use the device as a phone I wouldn't care, but it is just an expensive toy a decent portion of my day as it is right now.

Part of my point in all this is that I am in an area that has good Sprint coverage, the only difference between my usage is the phone. I was consistently on 4G with my Evo now I very rarely can connect or stay connected, I always had cell service on my Evo, now lots of dropped calls and static and unable to send/recieve texts unless under open sky.

Your best bet might be to try a bunch of different modems. [modems here = radios on other devices like HTC]
You'll have to root and add CWM to flash them. Modems are build 'independant'. Meaing you could be on EL29 and use an FG20 modem if you'd like. By far the best reception (both 3g an 4g) has been on the FG20.
If you want to keep your phone on EL29 stock use sfhub's 'Autoroot' and add EL29+CWM-Rogue. http://forum.xda-developers.com/showthread.php?t=1342728
Hit up the 'Modem repository by rwilco12 http://forum.xda-developers.com/showthread.php?t=1662295
After each modem flash I suggest updating the PRL and Profile too.
Find one that gives you the best signal for your area.
There are also '3g/4g speed tweak' posts in this forum That will work on GB and ICS builds.
Good luck.

You would think they would've mellowed this out of the all the phones by now, but you may be experiencing the infamous Loss of Service (LOS) issue this phone wrought when it was first released.

You can either use odin or a dialer code + your MSL.
There are new PRL out and I get a better signal now and better 3g speeds. Update prl and profile first. Next try different modems, I like FE22
Thank you everyone. I just updated the PRL and Profile again. I'll see if that makes any difference and if not I will start running through the modems. If I find something that works I'll post back.
My story begins when i got my new shiny D710 over a year ago. I loved the stock ROM that it came with (i wish i knew what version it was). Battery life was great! Signal was good inside my basement apt. i mean, i had 2 to 3+ voice bars and call quality was good in NYC.
updates kept coming through and then came the dreaded ICS update nightmare. every call was a dropped call or just no signal at all (stop sign). i gave the updates another month or two to see if anything got better, and it did not. i made a bold decision to wipe my entire phone completely and go back to GB EL29 stock, which came rooted. I was lucky enough to move into another decent apt. on an upper floor but STILL had really bad voice signal strength on EL29, 1 bar or no signal at all. it takes about 10 minutes for roaming to kick in, then it disappears after my call is completed. is it my phone or my ROM? Can anyone suggest a ROM that enhances the voice signal? it doesnt have to be GB, but i do enjoy it's battery life without having to install/tweak crazy battery saver apps. 4G data gets a full strength signal so i dont know what i am doing wrong.
My emergency flip phone from virgin mobile prepaid has full bars compared to this thing! both are CMDA!
I myself live in NYC and for me I was using Stock Rooted FL16. That gave me pretty decent battery life as well as pretty good signal. But battery life is different for everybody and every device. Hope that helps.. :thumbup:

Try different modems. There is a sticky in the development section.
funny how i am getting full bars inside my apt. while voice roaming. is sprint limiting my call capabilities on purpose? roaming on another carrier is a no brainer. it doesnt seem like the phone is the issue. i might just give FL16 a shot. is there no way to keep voice roaming ON all the time?
There's an app called "Roam Control" by MrGreg for rooted phones where you can force roam. "Not roam control" is in Google Play Store, you can get Roam Control at the developer's website

I absolutely agree with this. It sounds like your problem started when you received an OTA update that changed your modem.
If you flashed a rom zip file, it did not change the modem. The modem must be flashed separately. Try flashing a GB modem.
If you want to use a GB rom, I suggest Caukulin's v3.0. Everything works perfect and the battery life is the best I have ever had on this phone.
I was never able to get a good signal at home. I can go about 1/4 mile in any direction and get a good signal. I got tired of dropping nearly every call so I solved the problem by using a custom prl that uses Verizon's towers. Haven't had a dropped call since.

Hi, I have a galaxy S3 with T-mobile. I'm in a place where I have excellent 4G speeds (about 5-6 Mbps :speedtest), I noticed that when I'm on a call the 4G data speed drops to useless speeds. I can barely open a website or download an app. Speedtest shows like 500+ ping and about 500kbps download which is NOT constant (goes up, stops, goes down, etc). Real speed is way less than that. Websites don't open or take forever.. Is this normal? I am using stock rom (but also happened with other roms). I went back to stock thinking that this was a problem with other roms only, but the same thing happen with stock rom. Any ideas/clues/solutions? thanks in advance
Long ping times is normal due to how it operates. But only 5-6mbps? That's pretty slow. Most get averages of 13-18mbps and some get averages around 25.
Try the different modems to see which will be better for your location.

So, its kind of normal to get slower speed while on a call?
It would seem a logical conclusion. But I've never tested it. But I've never had anything not load or go slow enough for me to notice. If I think about it on my next call ill try to test it out.

Ok thanks, The problem here is that I find it way to slow.. lets say I'm downloading a file with no phone call going and I get 600KB/s, during I call I get like 16 to 40KB/s at most... It's like having dial up again... way to slow.. I think something is not right but can't figure out what, since I reverted back to stock wiped everything and also formatted the system after installing stock..
Have you checked your imei or ever lost it?
If not you should really try the different modems.
If this is a recent development you should also call support to see if they have any tower issues in your area.

IMEI still intact, and have never lost it. I will try with different modems thank you! I'm not sure if this is a new issue since I didn't use my internet as I am using it now while on a call before, also I moved from Puerto Rico to the states for a few months, so there are many variables at the same time. But will try with the modems.
Another question, when I odin Stock (not rooted) ROM does everything (incl. modem, kernel, etc) goes back to stock?

Hello, spent the whole day testing out every single JB modem from your post and none of them solved my problem... did find better speeds with some on them while not on a call. But as soon as I'm on a call the speed drops to about 47kbps, looks like a cap or something because I get constant speed of 47-49 kbps. Sometimes it goes over the cap and works normally but for a few seconds then the speed drops and its not constant anymore until it reaches around 47kbps... This is so frustrating... is there anything else that I can try out??

Flash the LJC firmware package. Third firmware link in my signature. This is for SGH-T999 (d2tmo) only. Unsure about the download cap while talking on the phone. Aren't the two separate? Cell and data, right? Shouldn't be a cap then, but I've never been talking on the phone while downloading a file. I will try it if I think about it tomorrow.
5-6Mbps is not bad. It just depends so much on where you are. My fastest test ever was the other day @ 14.4Mbps. It's not a big city, but it's sizable. It's usually under 10Mbps in that location. And normally less than that everywhere else in the area. There are some areas that put me on Edge. Might as well just turn on airplane mode. Because T-Mobile's Edge... is actually worse than no data connection at all.
Thank you, will try that tomorrow. 5-6mbps is fine for me but that is without call. While on call is like 0.37mbps constant or really bad ups and downs.. is like edge (worst than not having connection at all).. anyways will try and report back. Thanks again

Sorry I couldn't remember this before, but I have a theory that could explain what's going on there.
Voice calls and 2g (GPRS) both share the same frequency spectrum. I remember doing some 3g research in the past and one of the benefits to the introduction of 3g was more overall bandwidth for all, even those left on 2g. At the time, 2g data service was greatly impacted by how much voice traffic was going across the network at any given time.
During peak voice call times, there was less bandwidth for mobile data users because the tech was designed to give priority to the calls. This meant even slower than usual 2g data speeds.
But as people moved to 3g, there were less using 2g for data lessening the impact caused by voice and sms communications.
So what I'm getting at is when you are on a call, that call is going across 2g frequencies, meaning you are connected to 2g. (Though 4g data should still be available to you regardless. But it may have something to do with what you're experiencing.)
Keep in mind that this was 3 or 4 years ago. I'd think that it'd work differently now. But it is possible that they never changed the fact that voice shares its spectrum with 2g. I could be seriously off with all of this, but I still thought I'd mention it since it would make a little sense with the speeds you're seeing.
The thing is, the S3.is capable of using DC-HSPA (dual carrier) which means it can use 2 different signals at once (one from T-Mobile, one from a partner carrier) for greater speeds (HSPA+42). So I don't understand why it won't use this same tech to give you better data speeds while on a call.
I know I've used mobile data while on the phone before, and never felt like the qos was lacking. But I never speed tested it either.
The more I think about it though, the more I'm thinking it's either firmware (see aerowinders post above), hardware, or you're connecting to a tower that either has problems or hasn't been upgraded in a long time. I don't believe that what you're seeing is normal operation.
Of course every bit of this is speculation at this point. Hope no one thinks I wasted their time with it. I thought it may spark some ideas though!
