Data and Voice at same time on Samsung Vibrant

Has anyone had success in being on the phone using voice, and browsing the internet, using data, at the same time on the Samsung Vibrant, with T-Mobile?
I was able to perform this most of the time with my HTC HD2, with T-Mobile.
I searched, and can't really find an exact answer.

It worked but i was using wifi

Yeah, mine probably works on Wifi, but I am talking about mobile data, such as 3G. My HD2 did this most of the time.

If you are on 3G then yes you can.

This really only works well with a fairly strong 3G signal. Otherwise you may drop to 2G during the call and only be able to access data over wifi.

It works for me some times. Each
time I try I get different results some slow some fast or not at all. I am in the same place so its not my location. Its odd u was tempted to post a similar question.

Yes, I can use google maps, drive my car, and talk on the bluetooth all at the same time. The Vibrant works great. Only when it drops to Edge speeds, then ya lose the google maps, but the call keeps going.

Mine works as well, I've had my laptop tethered several times downloading large files, and answer a call and it keeps downloading no problem. I haven't noticed if if it's just a 2g/3g thing though as it usually stays on 3g for me most of the time.

I have no probelm doing voice and data both wifi and 3g.

wtf is up with ppl and the HD2.....

4g connects but no data transfer

Edit: the problem is with my 4g, not pdanet. On my phone itself with 4g on I can't load any webpages or get any other data connection. Worked last Friday, and haven't made any changes to the phone. Running burnt 1.3 with net 421 smartass nohavs.

Try reinstalling the pdaNet on both the phone and computer.
If still nothing, try turning your phone off then back on.
Sometimes people never turn their phones off.
Hope this helps.

i am one of those people who never turn off their phones >.>
anyway I had to reinstall it on the pc today anyway. It decided to not work anymore v.v havent reinstalled on my phone yet though.

Bump for edit

I have the same problem. I don't use pdanet. I can connect to the 4G network but I cant load a webpage or download anything. Basically no data transfer. I took it to a Sprint store and they are just going to replace the phone.

Transfer that's the word i was looking for
I'm going to reflash the wimax radio when I get home and my phone isn't dying, i'd hate to have to replace the phone.

Bah, reflashing the radio didn't help. Anyone got any ideas?

I am having the same problem with mine. It was working up until a few weeks ago, but now I can connect but it is painfully slow to load web pages. The page loads like 3/4's of the way, and then hangs for the rest of the page. The last 1/4 of loading takes a few minutes. That isn't even on a graphic-heavy page.
I am able to tether on my laptop though.
I am on OMJ's ROM, and have the most up-to-date radios that I know of

I've had this problem before too and the only way I found to fix it was to un-root and flash the stock rom. Then check if it works.
If it does work, root and flash a rom, I used sprint lovers rom and I didn't have any 4G issues with loading pages.....

Same here....recent issue....not sure what's up. Could be the network and not the phone maybe....what area are you trying to connect to 4g?

Buddy I work with has an evo too and connected just fine standing next to me.
I can't imagine it fried the radio itself since it connects fine.
Sent from my PC36100 using XDA App

well that blows....
i dont' have another evo to test it with....so I was HOPING it was a network thing....but I'm thinking it's not.
I checked my RSA keys.....they're still good.....
I have a NANDROID backup from a while ago when my 4g was still working...I'll flash it the next time I get to a 4g area and see if that fixes the problem.
I haven't touched my phone in terms of mods in over 2 months...so I'm wondering what the hell happened. I hate when **** like this just comes out of nowhere.
Please let me know via this thead if you have any new news.

new WiMax update is out in the dev forums. I'm going to flash now and see if it fixes my problems when i'm at work later (sidenote: my town has 4G, i just cant get it to connect at my house damn....trees)

Well I'm at a different place than normal but after flashing the new radio 4g is working.

I found out that my issue here was the app adfree.... if I stopped using that app, webpages on 4g load fine.

.....did nothing and 4g is working now....
aside from poking around in the adb shell to see if my RSA keys and MAC were still in tact (which they are)...my 4g started working again all by itself.
it was down for a week....and by "down" I mean that I could connect absolutely fine....get an IP....but could not transfer ANY data up or down. I did reboot serveral times while it was not working and that didn't fix the issue either.
Whatever....as long as it's working again...

Hmm i've been using adfree too but it didn't cause any problems. I agree Dell, as long as it's working.

T-mobile's network took a dump

Anyone else having issues with T-Mobiles network? I can't download anything, stopped getting FB stuff, Twitter doesn't work.

Working fine for me.

Where are you? Here in Northern Jersey I've got no problems...

Nevermind...I disabled the wireless networks and it started working again... wtf is up with that? First time that's happened. (running JL5)

I switch apns all the time. In quicksettings I use the apn switch but leave it on apn.droid instead of disabled (which actually DOES disable it) if I switch to apn.droid then it actually changes the way I connect to tmo... epc.tmobile.apndroid.com...(instead of epc.tmobile.com) I swear I get faster speeds.

I'm not sure what's going on but for the last couple of days my data connection is acting all messed up. Sometimes it works sometimes it doesn't. I've tried different modems and different roms. Also for the first tine ever Odin hangs every time I try to flash a modem.

Working fine for me. Faster than ever. Hit a new all time high in a speed test today. So I think the problem is on your end.

This happens to me on jl5. Didn't happen on ji6. It will still have bars, just no data. I have to switch to airplane mode and then back to get it working again. Happens a couple times a day.

That's odd. I've had JL5 since a few days after release and haven't had a single issue with data until today. I see full bars, data activity doesn't do anything except the green "out" arrow flashes but nothing comes in. I just disabled Data network and re-enabled it and now it's worked fine..

Please use proper language when making a thread. I modified the title of this thread because of it. Thanks.

I have similar happen on JL5, after a day or two (or an unknown set of actions). I will no longer be able to receive calls, but will get the VM alerts and be able to dial out. Data connection will then be hit/miss. I put the phone in airplane mode and take it off airplane mode and it works again.

Yeah,its a known froyo bug,it was even brought up several times in google's forum for the nexus one. it wasn't an issue in 2.1,but 2.2 (pretty much every build I've ever used on the G1,N1,vibrant,HD2,and Intercept) has the issue.

i think my phone's radio is broken.. now it doesnt switch between edge and 3G anymore.. stays on 3G
but download speed is really slow..painfully slow.. i was actually happy to get 3G in my room, but it's actually broken? LOL
i installed the signal app by imperial.. it stays on H - 93 dbm with the 3G symbol on the signal bar and consistent 3/4 bars.. what the hell..
hmmm..
maybe tmo 3g coverage has gotten better? but download speed is slow.. my phone may be broken.. ughhh

Check to see if you have it wcdma only. Settings->wireless networks->mobile network. It should be on wcdma/GSM (auto).

This also happens to me, I'm at JL5. Sometimes when using 3g my speed is lower than 100 kbps. I have to reconnect to make it work.

it is on auto mode..
they dont switch anymore.. from what i have observed, it stuck on the 3G symbol, but the actual download speed does switch between edge and 3g.. someitmes rendering a page is faster and sometimes it's slow..

im using the stock j16.. i already reset my phone, even reverted to stock jfd and flash via kies last night.. same issue
i haven't even dropped my phone at all.. not a bad drop at least..

I have the same problem on JL5. I just flashed Nero V3 this weekend as my first Froyo rom and I see today I cannot get online at work where 3G is iffy. If i switch it manually to GSM, then data works.

I actually flashed a custom rom hoping to fix an issue like this.
Back on stock my network data just stopped while browsing web pages or anything really. It would give the outgoing arrows but nothing would come back. After about 30 minutes or so it would start working again for a while.
Flashed to nero but it's still as prevalent as ever (maybe for a different reason now lol). Not sure if it's the phone or Tmo's network anymore, but it's not too big of an issue for me so I just have to remember to activate wifi if I need constant data for any period.

I have it set to GSM only because I don't live in a 3G area...

Not able to download data over 4G

I just moved to an area where 4G is available. I had used 4G earlier in this area, and it downloaded data just fine. But now, 4G connects, but no app can download any data. Even while running the Speed Test app, the attempt to connect to the server times out. Interestingly, data dowload/upload over 3G works fine.
I am not sure if this is due to the new PRL (that's the only thing that has changed), or some other cause. I performed the Handsfree Activation and PRL update, and also took the device into a store, to no avail.

Sounds like the WAN side is down, or you need a hard reset, or you need the modem reflashed via odin or perhaps a newer/different modem. If none of that works/is true, I'm willing to bet you need the radio replaced in your phone

My Friend has this same exact problem and it turned out that his 4g mac address was flagged @ sprint and they had to unblock it. They did not give a reason why, but they fixed it for him.

Int'l Note with Straight Talk BYOD - how STABLE is your DATA connection?

A quick background:
- I have an International Note - factory unlocked
- I signed up with Straight Talk few days ago - ordered the AT&T SIM Card
- Voice, text messaging and MMS works
- I am in Northern California
Problem is, the data connection is very UNSTABLE. I will have full bar, can browse the web and then.... BOOM! Suddenly no data, even though my phone show 3G and full bar. The only fix? Turn ON Airplane Mode, Turn it OFF or REBOOT, which is clunky and time consuming at best, especially when you are out and about.
This is not just an annoyance, but makes the phone almost unusable since I need data for my Exchange email, Google Navigation, etc. I DO NOT use the Note for tethering.
My APN is as folllow:
APN 1...
Name: Internet
APN: att.mvno
APN type: internet
APN type: default
APN 2...
Name: MMS
APN: att.mvno
MMSC: http://mmsc.cingular.com
MMS proxy: proxy.mvno.tracfone.com
MMS port: 80
APN type: mms
Fast Dormancy: Disabled
For those who use Straight Talk, could you tell me:
1). If you experiences the above
2). Where you are at
3). What APN do you use
4). Do you enable "Fast Dormancy"?
I am trying to figure it out if this is my Note or just ST flaking in my area.

I had the same problem with fast dormancy disabled so ok re-enabled it and it has been fine since.

Same issues here with an att sim and tried both single apn settings that came with straight talk and the two separate ones as you have. Also tried both fast dormancy enabled and disabled with same sketchy results. My location is Milwaukee, WI. Seems prone to disconnect right right after I connect to the market. Turning on and off the data connection re-establishes the connection though.

I used to have the OP's issue constantly here in Southern California too until I re-enabled Fast Dormancy and it's been pretty good since for me as well. Also have better luck with the 2 separate APN's that you're using.

That's interesting... it seems that I have to ENABLE Fast Dormancy for a stable data connection. I will try that and will update here.
I wonder if it has something to do with which tower I am connecting to...

Its really odd because everywhere I read AT&T doesnt support fast dormancy..
I still think its something at&t does to prepaid because my gf's SGS2 doesnt have that problem and I dont seem to notice it when I used her sim card..I'm on ICS and theres no way to turn fast dormancy off or on.

Yeah, I was thinking maybe some areas had upgraded equipment that supports it or something? Like you one of the first things I did was disable it per the instructions in the ST thread and never tried with it enabled until recently just out of curiosity.

I'm in the sacramento area, using the same settings with great results. Occasionally I have to toggle data, maybe once every two weeks, but not too inconvenient.

I turned ON Fast Dormancy and I was getting even unstable data, so I turned it OFF.
I was driving to another city today for lunch and I noticed my data connection was pretty stable. I had been doing a lot of testing: Google Maps, Email, Pulse News app, etc.
However, one thing is consistent: everytime I open Android Market (Google Play now), it will load UP until where I want to DOWNLOAD an APP (for testing - small apps - less than 2 Mb), the data connection shuts off....same problem as what I posted above.
I tried doing so about 4 times in 3 different location: home, work and lunch place, each location is about 5 miles apart. Same results.
Is Straight Talk monitoring and BLOCKING app download?

I'm using straight talk on my gf's S2 with tethering and its blazing fast (6 Mbps down and 1.1 Mbps up) and stable right now. Although I'm in Michigan atm (heading to California tomorrow). I plan to switch from AT&T's price gouging plan to straight talk when I get back so I'll let you guys know how it is in Modesto.

I have the same issue with market and sporadically, otherwise.
I don't think this is a straight talk thing. It doesn't make sense.

But if I access Android Market using Wifi, it NEVER FAILED. I access it using office network, home network, Clear HotSpot and Barnes and Nobles WiFi.
With ST, I got "No connection" after attempting to download.
Yeah, doesn't make sense, but this is what I found after numerous testing today...

Even when my data connection used to be flaky with Fast Dormancy disabled before I re-enabled it, I was always able to install & update apps from the Market. The weird thing is that it was pretty much only NON-Google apps that gave me problems with the data dropping out.
I would call ST Tech Support tomorrow if I were you and see if they can check your account and stuff.

I am in Northern California as well, Fremont to be exact. I have not noticed any problems with data while out and about here. I use the exact setting as posted in post 1 in this thread.
While at home, I just turned off wifi, and tried to connect to the Play store, No Connection - Retry. So I turned on/off Flight Mode, went back to the Play store, and was able to download a couple of things no problem.
This is pretty the same thing that would happen to me on my last Android phone, so maybe it is more of a Android thing than it is a Straight Talk thing.
Other than this, my Straight Talk data connection seems to be fine when I'm out and about.

Thanks for the info. So it seems more of Android OS problem.
The thing that intrigued me is that this issue doesn't happen to my 3 other Android phone, which are running on At&t, Verizon and Virgin Mobile.

Same here. I've been using nothing but Android since the G1 and I've never had these issues until the Note on ST, so I don't think that it's an Android OS issue UNLESS Samsung has a bug in the OS on the Note.
When I have time I'll do a search in the Galaxy Nexus forum or something to see if there are any problems with people on ST there...

I'm up in the grass valley area. Same set up as you. (But I did not touch Fast Dormancy).
It works pretty well, but I do see the signal get lost every once in a while. I just wait a sec and it reconnects.

I had inter.. data connect issues for the longest time..i would constantly have data stop and have to turn on and off airplane mode to get it back..
market would fail to load etc
i changed to a single APN using the settings in this post and my data hasnt dropped out since..

While custom rom'ing I was using Straight Talks APN settings w/ fast dormancy off and had no problems in downtown Chicago and on the north side around Wrigleyville where I reside.
W/ that said I installed the Chinese ICS Leak when it first came out and I had worse signals than on the GB rom's. Could have been the radio I flashed.
