[Q] HSUPA and Data on Captivate Help

I seem to be having an issue with my data and am trying to narrow down the reasons for my problem. The issue is I CANNOT use HSUPA (H) for data, I always get a connection timed out issue. I put the phone in 2G GSM mode only and have data working, but of course I was spoiled with better speed I can't stand it.
My question is if AT&T could be doing upgrades to the towers in my area, will that affect my speeds, or is something broken internally in my phone. When I select WCDMA mode, it takes FOREVER for it to connect and says searching for a long time but does connect or displays (H) with 3/4 bars of signal. My friend has an unrooted captivate on 3G and has no issue with data. Does anyone know the cause of this.
I have tried a few different modems (jl3, jk4, kp1....) all the same and have tried 2 different OS's with same data timed out issues while trying to use (H). I am currently in the process of flashing back to stock to see if that will resolve the issue. Thank you for your time guys.

H doesn't necessary mean HSUPA. It simply means HSPA (HSDPA only or HSDPA and HSUPA). You didn't mention anything about your firmware but I guess you are experiment with non-Captivate firmware and modem combination trying to get HDUPA working. From what you described, it seems your current firmware and modem combinations lacks 850MHz support for 3G (most European firmwares lacks 850Mhz) and your local tower happens to use 850MHz, not 1900Mhz. Just a guess.

Make sure you have the modern set to proper frequency (WCDMA 850 or 1900) for your area. The modem thread can tell you all about how to do it.

Sorry guys, I guess that was an important part I forgot. I was running Andromeda and thought the same so tried Cognition 4.1.1. Also after going to stock 2.1 I still have the data issue. I can connect to wifi just fine, but no using ATT data will work.
I called customer service and walked through the steps as usual and after some looking into my area, he said there were 3 towers reporting severely degraded. It just sucks seeing my friends phones working with no issues. He said that repairs are stated to be finished sometime in the next few days and to call back later in the week if the problem persists.

Looks like you tried both i897ROM and non-i897 ROM, so it's not firmware related.
Did you try to put someone else's SIM into ur captivate? How about some other devices in ur area?

I didn't think about trying my friends sim card. I will test tomorrow morning. Ty for the idea to isolate the problem to my phone!

umm not really related to your phone. but im suggesting its the tower upgrades getting them ready for 4G that is causing your phone to act up. i have a HD2 and we have 3G down here. but since early march i get nothing but EDGE. what happens in the month march? AT&T will be launching 4G in selected markets. it was confirmed once i was talking to a AT&T tech. so im just waiting to see what happens in the end of this month.
NOTE: it could also be your sim card having problems. AT&T replaced mine thinking it was a problem with the sim card since i have a AT&T native W350 and i was getting the same problems. call them up again and ask to talk to a tech and tell them your having a problem with your sim card. they will set you up a appointment at a corporate store. free of charge.

Is it?

you would have data, but no voice

Sorry for nor replying sooner. My 3G data seems to be working again. My lack of in depth knowledge is why I put the hsupa above when my phone displayed H I didn't know what to call it.
It must have been tower upgrades. I didn't restart my phone and left it on the charger overnight and the next morning I had no issues. I did a reboot of the phone as a test and connected with data with no issue. Too bad as I was close to getting a replacement, though it would suck and be my luck to get one with other issues. Mine is a 1007 and works perfect (other than the obvious GPS.)

Data connection dropped for no reason

This is starting to bug me..... for no reason the 4g connection and even when I turn off the mobile network, wait a few minutes and turn it back on, it still wont work until I reboot the phone. Sometimes rebooting it doesn't work and I have to pull the battery.
Anyone know whats causing this? When this is happening I see the ^ arrow on the 4g connection lit up like a christmas tree but nothing is uploading and theres no data connection....... HELP!

Mine dropped Last night for the first time. When I first got the phone it flip from 3g to 4g at my job. Last night finally went dead. I rebooted and still no network. Then I used the new LTE switch to keep it @3g only. It worked.

Hey Stoneskin,
I live in Hawaii and I have the very same issue as well. I picked up 4g easily in the "so called" extended 4g coverage region when I first got the TB. Then about the middle of last week, poof, no more 4g except for in the true 4g areas. My thought is because so many people were having 4g connectivity issues in these extended area, VZW simply stopped allowing it as a troubleshooting measure that apparently is still going on. I brought this up to VZW tech support and they were clueless as usual. I also posted in the VZW Community Forum hoping to get an answer, but none thus far.

you could try dialing ##778# and pressing send, select edit mode, password is 000000 and then under modem settings change it to rev A. then press the menu button to save and reboot. it has helped me out in the El paso area. friend showed it to me the other day Far as i can tell is that it disables the new network that allows voice and data at the same time since that's the only difference i have noticed other than not loosing my connection anymore. I just a heads up this does not work on the latest version of virus rom RC1B3 sensless but did with previous version and several other roms i had tried

Thanks for the tip, but it didn't work. VZW must have changed something to where extended coverage area no longer get 4g. Only those in true 4g areas. I really think this has a lot to do with the folks experiencing the constant drop 4g issues. They must have rationalized that if the extended area for 4g is not up to par and forcing 3g would be better. Only way I can explain it. From consistent 4g to only 3g. I sure miss the speeds.

Radio Reboot Cause and What to DO!

OK Guys and Gals, Here is what is going on with the radio issue. No Matter WHAT radio combos you may be using. As some of you may know by my earlier posts I live in a huge 4G network and never get anything, but 4G and (3G only for a min on boot) This is why I didn't have ANY issue's until I got curious and wanted to try something. On our tbolts, if you try to make a call while in 3G the 3G will drop out until the call is over. I went back to froyo, got pissed and went strait back to GB (doesn't matter what Rom as all the dev have clearly stated) when I did go back to GB things were tight as usual. worked like a charm. I used it as I normally would and everything was fine. upon a self induced restart, before my phone had a chance to obtain 4G (still in 3G) I decided to make a test call to see if the 3G would drop. It didn't. Quickly after I ended the call the phone booted in to bootloader. Thank God I had removed the GB RUU because I don't have a card reader to remove the RUU. I forgot to mention I do have the latest Rom Mgr and was able to get into recovery and simply reboot. After that reboot I would get to my home screen, but this time the 3G only would come up and then reboot. Time after time of rebooting I tried other things such as toggle radio to just grab 4G, then the phone rebooted again! upon the next full boot I quickly moved the original froyo radio strait to the sd card. And yet another reboot. This time I got a Rom Mgr error and noticed that Rom mgr was no longer flashed!!! I flashed it real quick because I knew another reboot was on its way. Rom mgr flashed and I told it to boot in to recovery. Thank **** I flashed Rom manager because if not I would be in continuous boots like the unfortunate others. Once in recovery I Realized that I had told my phone to go in to recovery via Rom mgr. and if I did a restore, the phone would have booted back up with my froyo rom but with the GB radio! so I told CWR to just reboot so I could tell the phone to go into recovery via the pwr restart option (thus not restarting after I flashed my froyo recovery) Once recovery of my froyo rom was complete I used ADB to reboot bootloader and SUCCESS! Bottom line you can not make a call while on 3G with any of the current GB radios, you gotta be quick, Make sure ROM mgr is actually flashed!!!! and hopefully can dump the froyo radio on to your SD card before an inevitable reboot happens! and have some ADB knowledge. I'm certain this is whats going on! People make a call while in 3G and its all down hill from there. So dont bother with telling radio settings to stick with one band. Once this happens, there is no turning back. Any questions PM me. I'm glad I tried this out before Vaca tomorrow with a FUBAR Tbolt
Hope this helps developers somehow. Good luck!

I make calls all day on 3g

Only 3g here in new Mexico and no.issues here. Maybe its more to do with making a call while the phone is trying to.connect to the 4g.

Good point, but sometimes you never know when that may happen. Ie. Your driving in a 3g area while on a call, hang up and it doesn't get the 4g in the new area ur at and what I mentioned is most likely going to happen. *shrugs*

Maybe, but that one time when u make a 3g call n hang up, if your in a 4g area then, this could happen n Tom manager may drop its cwr flash n **** ya up. Just a heads up. Make a 3g call, but if ur going in a 4g area make damn sure u check rom Mgr to see if cwr is still flashed.

I ran a GB rom and radio for over a week set to only 3G and I am in a STRONG 4G area. Made many calls and had no issue.
*edit: Correct me if I'm wrong but your data (3G) drops when in a call, when set to 3G only, due to the fact that you can't have simultaneous data and voice. That is what 4G (LTE) is providing. I open and close the browser a couple of times or toggle airplane mode and it comes back.

Not until Voice over LTE will that be accurate...LTE is data only at this point.
Turn off data and you can still make a call, send and receive SMS/MMS.

Q: I don't have data anymore

So I recently bought the girlfriend a Samsung Galaxy S 4g. Definitely a bit different than the Evo in terms of the overall process. It didn't help that I started out in the Vibrant forums somehow...
Anyway. As it stands right now I have her phone all rooted and it has CWM and I'm using the Valhalla ROM. The issue is that she doesn't have data.... and when I go into wireless networks and check out the mobile networks and such, I can never actually see T-Mobile. If I search I can see AT&T, which I connect to and I start roaming. If I do this I still don't actually have internet. I can't use the market, or the web browser or facebook or anything that requires data. The browser will sometimes redirect me to some web2go website, otherwise it just times out or says it can't connect to the server.
So does anybody know what's going on? Please let me know if you need any more details.
I've never had trouble like this between my Evo, or my Epic 4g Touch or any friends phones. I've also tried going back to 100% stock unrooted GB and I still have the exact same problem. The ROM doesn't seem to matter, neither does being rooted.

Since you are running Valhalla bring down the notification bar and make sure you have the data toggle on.

Yep, it's definitely toggled to on. I even cycle airplane mode and make sure it's on afterwards.

Only other thing I would suggest is a factory reset. The phone should be picking up the T-mobile network without any problems. But if rooted or not and on stock vs custom rom the issue remains you may just have to set it back to stock and send it in for replacement.
And I know this is a silly question but make sure you call T-mobile and verify that this line has data plan. It has happened in the past when I added a line that it wasn't provisioned correctly and out of the blue the data stopped working. The service was automatically removed due to a reps mistake.

Check your APN settings. Should be T-Mobile's, if not then that's what causing the issue. Just look up for those on google.
Sent from my SGS4G using xda forum app

My APN settings are correct. I've now tried several other APN settings though, and this hasn't helped.
I know this phone is on a data plan. It's on the $50.00 a month prepaid. It did work when we got it, and after it was rooted. I just noticed recently that it stopped working, and I'm not sure at what point it happened, and if it has anything to do with what I've done.
I called tmobile and they said they couldn't see any network related issues going on. Just my phone not connecting, so it was made a ticket for the engineers I guess haha. They are supposed to work on it, and they usually will either fix it and never contact you, or call you if they need you to do something.

Bump.
I've been in really good service areas with full bars T-Mobile and I still don't have internet. So I really don't know what's up. The "T-Mobile engineers" haven't called me back or fixed anything yet.
I'm about to bring myself back to stock and bring it in to a store.

Bring it back to stock & maybe put it in recovery mode & wipe caches & do factory reset again. See if that helps before returning it.

Having the same Data problem
I had an unlocked ATT BB Curve on T-Mobile and the data was working (although very slow...)
I decided to try out a "Vibrant" hoping to be able to install ICS via Cyanablahblah.
Searching on Ebay I bought one only it turned out to be the 4G (it didn't realize there was a difference.)
Since then I can't get DATA on the 4G except in WiFi.
On the network it goes to the page: u.web2go.com and says my data plan does not work on this device.
Has anybody had any success with this problem ?
Could it be a 4G issue ? Before DATA came from Edge.

Is there any way to fool it with a 3G modem flash or something ?
I think I screwed up when I bought the phone not realizing there were 2 variants of the "Vibrant."
I wonder if I would have this problem with the earlier (non "V") 3g phone.

Probably. If it were just the 3G/4G causing the problem, you can force the SGS4G to only use 2G networks in the data settings... but if it's anything like the old Verizon bits with tethering and other data, they check for specific data strings that are harder to fake... I mean, set.

[Q] Nexus S 4G - DATA DROPS

I have been having this problem with both of my Nexus S 4G ever since I got them 2 months ago.
My data drops out frequently and takes a while to get back up. If I have 4G enabled, then I have to manually reconnect it as it will not do it on it's own. This happens inside AND outside. Driving down the road or just standing in one spot.
I've tried all of the radios (basebands) and about 7 different ROMs and versions.
I've refreshed the data profile, PRL, and even tried the roaming Verizon PRL and Hybrid PRL.
Gone back to stock and tried everything from scratch. Still the same problem.
Dallas/Fort Worth Area
Network: Sprint
Baseband: D720SPRKE1
PRL Version: P:40447
I contacted Sprint and they just told me to update the profile & PRL.....
Any suggestions?

I'm not familiar with the CDMA nexus s, but are you able to change APN's? At one point I'd be able to connect to 3g (I have an I9020A), but every minute or so it would drop, so I fixed up the APN's for my carrier.

iv had a few data issues
forcing PRL and account updates has fixed it a couple of times
i'v bought used phones that iv had
to have sprint force update
im on LC1
[altho i cant tell any significant difference here]
and my prl is 61086
[a business account]
im currently on slim
make sure your mobile network
is set to roam
is not set to home only

Am I the only one with this problem? As I'm typing this I lost data but still had 3 bars. I never drop calls but only data.
Help please. This is driving me nuts.

I almost always have to use 4G (if possible) since 3G speeds are slower than dial-up.
I've tried rebooting and leaving 4G off, and still the same. Even tried going back to Gingerbread.

when data fails?
mine shows "unavailable" when it's wonky
and wont re-aquire till i reboot.
i'v seen this on 2 phones
off and on including on oem 2.3.7
fwiw

Am I the only one with this problem?

I have the same problems. From what I understand, its a problem with the hardware. I can confirm that's probably the case, because I've tried many different ROMs (stock, cm, etc...) and they all have the same radio issues (3g/4g and wifi)...

I have an NS4G in the DFW area and haven't seen the issues you're reporting. I'm currently on 4.0.4 with D720SPRLC1 baseband. Maybe I'm just lucky and have a good signal at work and home. It's very rare that I find an area of DFW where I don't get any data signal at all. Not sure what to suggest.

I get random drops too and i hate it. My 3g speeds are fairly good even above 1 mbps. Highest i ever got on 3g was 1.51 mbps

Mine will lose data if I'm in a coverage free area for an extended period of time, when I'm back in range 3g icon will show up just never reconnect. A reboot fixes it

Certain Areas
There are certain areas where I live that data just disappears. Although this is just a network thing I believe. It's weird though when I am driving it's like a 10 second drop and then all is good. Hope you get a solid fix!:victory:

Backup 4g Partition
REMOVED - was a bad idea.

I've actually replaced BOTH of the phones with brand new NS4Gs and they shipped with ICS.
Still the same problem.
This is driving me nuts. I was driving and trying to download Maps for the new phone from the Play Store and it took 6 tries. Kept saying RETRY.
What I've come to believe is happening is:
When 4G connects, 3G disconnects. When 4G drops (which is does frequently), 3G has to reconnect.
***Is there a way to keep 3G "on" in the background while 4G is connected?*** Maybe a way for the radio to transition back and forth?
