cannot get 3g to work - Captivate General

hey guys,
for over two months now, my phones does not want to connect to the 3g, even in places where it used to (ie, my house). I have tried using the service menu, different apps, the network options, and have looked high and low but all the threads I've found end without an answer.
Right now i have,
2.2
Baseband: I896UXJL1
cognition 3.04
Any suggestions would be greatly appreciated.

What happens if you go back to stock?
Sent transparently through the tubes.

hmm good questions, last week when i went into 2.1 to update cognition it was on. After I installed cognition it was on for 3-4 days, but then over night it switched by it self and I have not been able to get it back

Have any other 3G att phones, its a long shot but once I had a similar issue, put my sim in another phone left it on for a few min then put it back in my captivate and everything worked fine

If your phone has the extended power menu (hold power for options) there is a data network mode option, make sure it is activated. You may have hit it by accident.

What modem are you using? Have you tried flashing a different one?
Have you tried other roms?
I would consider going back to stock (sucks I know) for a few days and if it continues to happen, take it into att and see about a new sim card or a replacement. If it doesn't happen again, try a different rom.

Try going into settings - wireless and network - mobile networks - Access point names - Click the menu button - Reset Defaults.
Had a co-worker running stock and his 3G would not come on anymore I had him do this and has been working ok ever since.

[Q] Network Dropping

I just want to check in and see if any other Inspire owners are having this issue:
I have noticed that my phone occasionally drops the network connection and doesn't get it back right away. There are two different flavors of this issue that I have experienced:
1) I was walking my dogs today and the phone suddenly dropped it's connection to AT&T completely. After a few seconds, it reconnected and everything was fine. I was in an area with good coverage and the status bar showed no connection at all.
2) When home, I leave the Wifi on. Earlier today, when I tried to make a call, it simply wouldn't dial out. Then I tried to open a web page and nothing (after turning wifi off). I had to switch airplane mode on and back off to reset the connection. I also received several text messages at once, all of which had been sent hours before (as indicated by the time stamp on the message). It's almost like the phone has an issue swapping back and forth between the carrier connection and the wifi.
Is anyone else experiencing anything like this?
As an update, I noticed that when the wifi is on, there's a check mark under the H+ symbol (rather than the up/down arrows) and when I switch off Wifi, it doesn't go away. During this time, I have no cellular data. Switching airplane mode off and on doesn't seem to work. Sometimes it recovers on its own. Other times, I have to turn the wifi off and on several times.
This is annoying. It seems to be having issues doing the hand-off between Wifi and cellular data. This is really the only issue I have with the phone. Hope they roll out a fix soon.
I had the same problem. I thought it was because I had to add my own APN. (I could not switch my plan around because it was a work SIM). This caused SMS messages to not go out and an overall bad network experience on the phone. I have since returned the phone because I need a reliable network connection and the ability to send/receive SMS messages at all times. Once a fix is found I will be back. I liked the phone alot otherwise.
Are you by any chance using the SIM from another phone? I had the exact same issue yesterday and data did not work for me until I called AT&T and had them update IMEI number from Captivate to Inspire. Hope that helps.

Nope. I made it a point to have them activate it in the AT&T store with a new sim because I had read about people having issues when they transfer their SIM. I also had and iPhone 4 previously, so transferring wasn't really an option. I'm definitely on the right data plan, too.
I left the wifi off all night and it did it to me again today. The check mark shows up under the H and it loses all data connectivity. I'm not sure what is causing this, but I'd love to know if there's some kind of workaround. I have messed with a few options (like the data always on option) and haven't had any luck.

I was using a SIM from another phone. It is the SIM card from my Work phone and I can not change the plan. It does have unlimited text and internet I just cant change it to a 4G plan. I had added the APN that is floating around here and that worked except I was having the same problem as the OP.

Like I said, my issue was very much like yours and OP's and adding cutom APN made no difference until I called AT&T and had them update IMEI on my account. Presto, all problems went away instantly. I understand that it's not an option for you, sorry
have you tried creating a new apn? try creating one using these settings.

Just did this. Thought it might have resolved it at first, but it didn't. Basically, when I put the phone down for a while, it's like the data connection goes to sleep and doesn't wake up. When I turn the screen on, there's no mobile data. Sometimes, the dual arrows are visible under the "H", but only the up arrow is lit. Other times, the check mark (meaning no data) shows up under th "H" and stays there. Switching Airplane mode off and on will reset the connection.
I hate to say it, but the phone may have to go back. I love everything else about the phone, but this bug is too major to wait for an update or fix. What good is smartphone that doesn't get data reliably?
are you running the stock rom? i haven't been using that rom much so it may behave differently than the custom roms.
i don't think its a common bug. i would see if you can get a replacement phone.

Definitely stock rom. No rooting or anything. I didn't notice this on the first day I had the phone because it was on Wifi almost all the time. I turned wifi off to test it and the issue persists. I suppose I should try resetting the phone first, though I'm not looking forward to setting it back up again. After that, I'll take it into AT&T. I'd love to keep the phone. Can't believe no one else is having this issue.

yeah, resetting it up is a pain. sorry, and i hope you get it fixed.
Just to say it again. I had the exact same problem as the OP. Maybe we both had a flaky phone?
Okay, turns out there's an issue with the AT&T tower closest to my house. I found out from a rep at AT&T. I haven't left home much at all this weekend, so I had no standard for comparison. I just verified it by turning the wifi off on my iPad and using 3G data. It has the same issue.
Of course, I had already done a factory reset and gone to the AT&T device support center, but at least my phone is fine.
As a side note: I love that Android restores your apps now. I always thought WebOS was awesome for doing that and that was what frustrated me most about Android, with as often as I swap phones.
Wow... Wish this was my problem. I switched back to my Palm Pre+ and my data works fine.

Data Problem, What Should I Do?

I just started having this issue, i can't connect to any data at all, i have tried battery pulls, using restart connection, running different roms, using restores where everything was working, doing a full wipe and then installing a new rom, but still no luck. Should i try just a factory restore? i also read that taking out the battery, then take out the sim card, booting the phone up with out the sim card in, getting errors and then shut it off and then put the sim card back in works, but im not sure which of those to try, any advice?
when that happened to me i did a factory reset and it worked afterward
Check around first, see if Verizon is having problems in your area. I know recently places have been popping up with sporadic outages.

But isn't installing a rom and wiping the data and cache the same as a factory restore?
I had this happen to me earlier this week. When I called Verizon support they told me that towers were down in my area, they told me the same when I called back the next day. Meanwhile, others who own the TB seemed to be having no issues. Finally I took my phone into a Verizon store and they are shipping me a replacement phone. They would not swap my phone in the store since I was a whopping 4 days beyond the 14 day return window...but, I digress.
The one workaround that I found in the meantime is to switch your modem settings. Dial ##778, select Edit Mode, enter 000000 as the password and select Modem Settings. Select Rev. A and choose Enable. Press your menu button and select Commit Changes. Your phone will reboot and you can use the LTE On/Off App (or just dial *#*#4636#*#* and choose Phone information) and switch the radio to CDMA Auto (PRL). That enabled me to have 3G data, though it seems extremely slow relative to 3G on my OG Droid. But, in a pinch it seems to work.
One additional bit of advice, in case you are running a custom ROM. I was running Virus ROM and ##778 would crash whenever I tried to run it. In order to swap the modem settings, I had to flash back to stock and make the updates, then flash back to Virus. I don't know if this is specific to Virus, but just an FYI.
Just tried on das bamf and worked fine (##778) must just be virus.

*#*#4636#*#* and tap on phone information and go to the box that says "CDMA+LTE" THATS default 3g and 4g and for only. 3g is auto prl

You won't get 4G on that setting, it turns the 4G radio off entirely. You would need to switch back to the CDMA + LTE/EvDo auto or LTE mode settings to get 4G. Ultimately, my issue ended up being a defective phone. You can try to wait it out and see if you get 4G back later, but you may just have a faulty device.
If that is the case, just remember to follow the instructions that jcase posted in the development forum to get your phone back to stock with s-on before taking it into a Verizon store. If you bring a rooted device in, I suspect they aren't going to honor any sort of warranty.
My phone had this problem too... turns out when I went into a 4g area the mobile network box got unchecked in the wireless & network settings.
I use the "verify with multiple devices method". I am tired of the standard VZW "towers are down in your area" bs answer.
If another tb, xoom, and bb have service and my tb doesn't, that tells me something is wrong.
I have a feeling that there is something seriously wrong with the network (implementation or backend hardware) that is causing this with 4G devices. Either that or the tb is to blame entirely for Verizon's 4G issues...... /rantoff..... LOL

Was having issues earlier today with 4G. The connection and signal were good, but no data would download. The white up arrow would light up, but the down arrow never would. It was like that for about 4 hours. It's working great now and speeds are disgustingly fast.. maybe VZ doing some maintenance?
EDIT: THis is in San Diego.

Factory Reset from bootloader worked for me. I had the exact same problem. Tried everything that was suggested, but no data still. Only enabling Rev. A worked.
Thanks for the help, the problem I'm having now is I got 3g but I can't get 4G back, I have tried to switch my settings back to get 4G using LTE on/off and by dialing the number, and I have had no luck, in those menus it tells me service type LTE but it is disconnected, and I get no data or 4G symbol in the status bar, so I'm confused if I maybe messed up a setting or what, so should I just try a factory restore via the bootloader and see if that works? Any other suggestions ?

I would try the factory reset from bootloader, but I was on the stock ROM when I did it. So I don't know if that would matter or not.

Just to reiterate, my 4G never came back. The phone was just broken. It sounds suspiciously like you are having the same issue. Maybe there is a manufacturing defect that makes this issue more prevalent with this phone right now? If you are in the 14 day return period, set your modem and radio settings back and get into the store ASAP to swap the phone out. Otherwise, call customer service and have them replace the phone. They will overnight you a new phone if you complain enough.
Ok I was looking through my modem settings after dialing ##778 and I had changed the rev a. Setting to enable, that got my 3g working, but what is eHRPD is that would I should have it on too have 3g/4g? But everytime I have tried setting it to that I get no data so is that the setting that is messed up?

[Q] Unable to get 4g

Alright, I'm a flash addict, love trying all the roms and well I was switching from bamf 2.0 beta 4, to Gingeritis VIII. I did my wipes and everything special, yet when I finally load it up, my 4g is not there. I'm in a 4g area, and I can get 3g but not my normal 4g. Not sure what to do, I even tried restoring back to my bamf rom with no luck. I had it before I did the switch and it was working fine. Anyone else having a issue or know what could be causing my problems? Forgot to mention I did try changing the radio settings and doing a fix permissions, neither did anything.
Did you update the radio?
Have you called Verizon to see if there is an outage? My 4g went down for a few hours yesterday, might just be them working on the network.
Radio was updated and I'll give big red a call, I mean its kinda odd I hold my 3g easily yet my 4g dies. I've had my 4g all night, and it did happen in the morning, so maybe they are working on it.
Called big red and they told me it would be back online soon just a short outage in the area. Came back online as I was typing this lmfao

Everyone needs to remember, VZW is constantly upgrading/testing/fixing their LTE network. Things like this will be going on most likely all year as they continue to roll out to more cities/markets. First thing to do if your 4G starts acting up is just give them a call. More likely than not, they are doing work, it's just coincidence that it stopped working right after a flash
Yeah I can't get 4g to work either. It might be because I don't have it yet. I figured I would just flash rom after rom till I find one that works.
Just trying to get past 10 posts.
I am also in a 4G area (Los angeles) and had 4G all the time but when I upgraded to the Gingerbread leak I lost it and yes I flashed new radio, its been about a week now. Haven't called big red yet and also haven't heard of updates in my area but 1 week, that's a long time. I also reverted to froyo with accompanying radio and no change...wondering if anyone else in LA area has the same problem or do I have a problem with my phones hardware...
Be sure to reboot the phone like 5 times. That brought it back for me.

I called tech support and let them know of the issue, said there is no 4g outages in my area (los angeles) and was instructed to factory reset, which i do before any rom install then i gotta call back-if and when i get this resolved i will post the outcome.
Not sure what rom you're on now, but whenever I flash something if I lose data I have to go into the antenna settings and force 4G for a while and it will pop back up

I'm still on Baseband 1.16.00.0223 and Software 1.12.605.6
Could it be since i'm rooted and have not applied the OTA, that verizon is refusing to authenticate my data (connection)? Because when i look at lteonoff, it says i'm connected to whatever network i specify, (LTE, CDMA - eHRPD OR Rev. A [if i go into ##778])
If I go to options ->software update -> check new, the 3G or 4G icon will pop up and checks for a newer firmware. It tells me there is a new update and i can press okay, defer, or deny. As soon as i exit that and try to use the browser, the 3/4G icon goes away. Should I update to the MR1 OTA?

Im just in a 3g area and everytime I go to a gigerbread rom and radio all I get is 1x. Then reverting started jot even fixing the problem. After about 10 flashes back and forth and rebooting a hung I finally ended up on Froyo with 3g. I'm staying here. Not worth my time to run gingerbread.
I was running a GB rom and this afternoon lost all data.
If I take out the sim card and reboot, I can get data for a minute or two...then it goes again.
I'm going back to stock and taking my phone in tomorrow.
Ugh to the guy that said call tech support to see if there is an outage, I don't work in a call center but do in a store and I hate when people come in or call for outages my suggestion is to follow @vzwsupport on Twitter they will let you know in no time and it keeps you from having to go through the menus and crap.

I re-flashed back to stock and now I've got 4G back.
If anyone is having these problems after running GB I would use JCase's "back to Froyo" flash before trying anything else.
Verizon has had a known problem of thunderbolts loosing its 4g, 3g and 1x. I had the same problem over a month ago when my phone was only able to receive calls and text. Had no data.. so I called them they had me do a factory reset and it fixed it

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.

You might try reflashing the ROM or maybe just flash a different modem. I had issues like that once when i was on black ice. If you had data before, there probably isn't anything wrong with your phone.

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.
Have you checked what your APN settings should be with the magics of Google?

I have, I've tried 3 different versions with no joy.
Update:
As per T-Mobile Tech,
Apparently Blackberry Data service does not work on non BB phones.
Needs Add on Data plan

tmob probably caught on that you're using a "4G" phone and will try to force you to upgrade your plan.

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.

They use your IMEI to tell what phone it is.

the OP was in 2011, so I'm pretty sure he already got it taken care of

Nexus 5 - Dropping network

My S3 died last week so I purchased a Nexus 5 and I've had nothing but issues with it since.
In 6 days it has dropped network about 10 times and just displays 'Emergency calls only' until I reboot it. It seems to be completely random.
Twice it has done it whilst streaming over 4g from YouTube, but it has also just done it whilst dormant overnight. I woke up the other day to find 'Emergency Calls Only' despite it being fine when I went to sleep.
After searching google I can now see that this seems to be a common issue with Nexus 5.
I'm seriously considering taking it back and getting something else, although I'd love to keep it if it works properly. Does anyone know the cause of the issue or have any workarounds? As I use the phone for out of hours calls for work, I can't afford to have it drop network whilst in my pocket and me not know about it...

Update radio or android, try different radios or reinsert sim. The network drop issue has been fix in 4.4.3

Do I have to root to try different radios? Android was updated when I got the phone and it's now on 4.4.4

You have to unlock the bootloader to try different radio's. There is a thread about it in the general section. Try to reinsert the sim first. It fixed it for me when I had the issue

OK I'll try the sim first before unlocking bootloader. Thanks

OK so I tried re-inserting the sim but still dropping network. The weird thing is that it has done 3 times in the exact same location on my way to work whilst I've been streaming. It's as if it loses 4g signal in that location but then fails to switch to 3g and instead I get left with no network connection / no bars (empty triangle). It then fails to pick up the network again until I reboot (tried re-registering on network and airplane mode on/off).

Hmmm that sounds like an apn or carrier issue. Maybe they can help you

OK so re-inserted sim and spoke to O2 who said settings are ok. However, it did it again this morning in the same location. That's 12 times in 8 days I've had the phone, 4 of those in the same location (give or take 100m).
I think I'll take the phone back before unlocking bootloader and trying a new radio, but any other suggestions before I do that ? Factory reset ?

You have drops in the same location? Is that only with the N5 or with other phones too?

I never had it with my S3 in 2 years, using the same route into work every day. I can't remember my S3 ever dropping network once....or if it did it picked up the network again automatically. Only difference was I wasn't on LTE with that.
It's not just that location though, it's happened 8 other times in other place nowhere near. I only made note of the same location because it's where I get off the tram coming into work. This morning I wasn't streaming or anything, it was just in my pocket, but I'd installed light flow to audibly alert me when it lost connection.

Maybe set it to 3g instead of LTE, or else RMA/send the device

Yeah I've seen suggestions about changing to 3g, but that defeats the object of me having an LTE phone and paying for 4g service. Thanks, I think I'll take the phone back. My mate has an N5 and although he said he'd experienced it in the past, he hasn't since being on 4.4.3 / 4.4.4

OK so I've been and swapped my N5 for a new one...they also gave me a new sim. Fingers crossed !!
I guess I am too late to add anything but anyway here is what I did and may be of help. After pulling out the sim, use a pencil eraser and rub it across the contacts on the sim card. If the contacts somehow get too much oil residue from finger tips or other "impurities" on the contact, you will get incomplete contacting sometimes and it works other times. The eraser will clean those contacts up for a better dirt free connection. When I was a electronics tech in the hi tech field, I fixed many issues that were just contact problems and the eraser did the trick. I have had this same problem on my other phones (blackberries and androids) and it seemed to work.

Thanks. Either the new phone or the new sim seem to have fixed the issue. I've not had a network disconnect since (been 5 days now).
