Hello everyone,
I got my Captivate yesterday shipped from letstalk.com. Everything with it has been working well, except I don't get a data connection with it at all, except WiFi.
As instructed by the sticker on the box the sim I am using is from my old phone, a Samsung SGH-A707 flip phone. The sim is a little over two years old. When the sim is in that phone, I get a 3G icon immediately.
I have tried turning the phone off, leaving it for several minutes, turning it back on again. Also removing the battery.
When I go to Settings, Wireless and Networks, Mobile Networks, Access Point Names, I see ATT WAP listed. I have tried adding another Access Point Network based on settings seen elsewhere in this forum which differed slightly by specifying a username and password, and not having the proxy and port set. But selecting this other APN has no change.
When I go to Network Operators all I see is an unselectable 'Default Setup' item. Others have reported seeing network connection information there, can anyone confirm on their Captivate?
Checking or unchecking 'Data roaming' does not seem to have any effect.
Under Settings, About Phone, Status the Mobile Network Type is listed as 'HSDPA' but Mobile Network State is 'Disconnected'.
LetsTalk are sending me a new SIM to try, but since I get a 3G connection on my old phone my suspicion is that this is a phone problem.
Does anyone have any other ideas though? Any help would be much appreciated.
Wow well you found something I hadn't yet. There was some talk about whether the captivate did hsdpa or not.. and according to the setting you looked at, it does. In that setting does it show your network is on aT&T? You shouldn't have to create a new APN, the default one should work. Sure you don't have the phone in airplane mode? I'm sure that's a stupid question, just asking.
If you don't have a 3G sim card I hear 3G wont work. You can get a new sim from ATT for free. Oh and about hsdpa ATT disables that Icon and uses a 3G one. I seen a test somewhere with two dif phones one with a 3G icon and one with the H getting the same speeds.

Yeah it shows AT&T under Network.
Nope, not in airplane mode, but thanks for checking, I'd rather you'd assume I was stupid than not ask me the question!

It is a 3G sim, at least that's what it is labeled as. Like I said I (apparently) got a 3G signal on my old phone. And a new sim is on the way.
on the sim does it say 3G with flames around it lol (thats how my last sim was and it was 3G)
I went to the ATT store to get my captivate. I had an old sim ATT logo with flames that worked in a N1, N97, Bold 9700 and iPhone. I too showed no 3G. They had to replace my sim and it started working. They couldn't explain it.

Great, that gives me some hope the new sim that is on the way could fix it, thanks!
I had this problem as well. This fix worked for me:
Settings > Wireless and network > Mobile Networks
Check both boxes
- Use packet data
- Data roaming
ATT / Captivate Android 2.2
Hope this helps,
Did you find a solution for this? I'm having the exact same problem with my Captivate. No 3G icon and no packet data connection or mms. When I try to go to a page it immediately gives me the "not found: check your data connection" page, and when I try to send a mms, the 3G icon appears like if it was trying to connect and send it and then disappears when the message fails to send.
I just updated to 2.2 today and I no longer have 3G as well.
just an FYI as long as wifi is turned on you will not see the 3g icon.
I have noticed that when you turn wifi off you generally will not see the 3g icon until you do something with the phone that requires data connections
Turn off wifi and try opening a website via browser...the 3G icon should pop-up automatically at that point

Hello sir, I tried this and now i have 3G(icon popped up and internet/mms works) but am i incurring roaming charges?
For me even that's not working, I think my stupid phone is broken.
When I got a refub'ed Captivate for my partner via AT&T online store since it was only $49, I followed the instructions that came on the box, and everything worked except no 3G/data. So thinking that it might be because of a refurb'ed unit, I called AT&T. They told me to bring it into a corp office store. Fortunately, there's one right down the street from me. I took it in, they fiddled with it for about an hour, including swapping 3 different SIMs, and told me that it was a defective phone. I asked then how do I get a replacement. The rep told me to contact cust service for them to ship a replacement out and it'll include instruction to ship the defective one back since they can't replace refurb unit there at the store. So I went out to my car, called the cust service. The cust service rep told me that I have to send the defective one in first before they'll send me a replacement. I got angry and I went right back in the store, grabbed the rep that was helping me out and told him to please talk to the cust service rep to work things out because I'm not leaving the store until it's resolved. So they talked on the phone for about another 30 min. Then they hung up. The rep fiddled with it for another min, then handed me the phone and the 3G/data was working. Appearantly it was the way that the phone was registered with the system, something was out of whack and 3G/data was not available for that phone line. I then recalled that when I ordered the phone from AT&T, I got an email with instructions that I had to follow, which I did, then I followed the instructions that came with the box. I didn't think much at the time, but it seems like the instruction was telling to do the same thing as the email's instruction was except it was via a slightly different way. So I think I might have inadvertly register the phone twice. In any case, when that happens, 3G/data is not available and yet, the reps checking in the system found the account was setup correctly with the proper plans, changed plans, swapped SIMs, and came to the conclusion of defective phone when the phone was perfectly fine. I don't know if this will help any one. But if your phone is not flashed or rooted, you might want to have AT&T check your account and phone registration.
Go to Settings -> Wireless and network -> Mobile networks -> Access Point Names. Inside that option go to Menu -> Reset to default. (Reboot your phone)
Worked for me, i have a samsung captivate thats rooted running on 2.2 froyo and i was deleting some user data,believe it was dialer data (do not delete that, it also deletes your texts) and i all of a sudden my internet stopped working,i tried every setting and i even think there weren't any APN in the list of APNs because of deleting rampage, so i reset my phone and after that i reset the APN back to default settings and rebooted my phone and it worked. For some of you guys, if it still has an APN(the cingular one) in the list of APNs then all you have to do is reset it back to default by clicking menu with the menu button on your phone and click reset. It should work.

Worked like a charm on my Samsung Vibrant S on Virigin ... this gem of a tip shall be remembered. This started yesterday on the road when data was needed for a work emergency. If only I'd known it then. :-(
Now to fix the Wi-fi from turning itself on and off of it's own free will. *sigh*
Thanks for posting on an old post Sreenadh. You saved the day!

...and, it looks like someone found it useful.. Five months, or five days, or five minutes.. If it isn't helping, why say anything at all?

Dude, thank you so much !
Hey all,
I just got my nexus 5, 2 days ago. When I am NOT connected to wifi my LTE Data connection drops after my screen has been off for about 3-5 minuets. When wifi is connected I don't lose my data connection. I can still receive Texts. Yes Background data is turned on. When the screen is on I am getting great speeds. I figured this out because I was not getting notificaions. When I turn the screen on and check my notification setting panel the LTE turns orange for about a second then goes back to white.
What I have tried
1. Turn off LTE Tried 3g and 2g. I had the same problem.
2. Tried alternate APN Settings. There are many variation to choose from for straight talk with a Google search.
2a. I am a tfdata sim on straight talk, FYI
3. Factory Data Reset
4. Re-flash Stock Factory rom and recovery. I was rooted and TWRP
5. Lock Bootloader
I have a call and email out to straight talk, waiting for a response, but thought I would post and see if anyone can think of anything I might of missed. Hope I don't have to send it back to Google.
Thanks In advance
Eric
Update
Just wanted to update in case someone else runs in to these issues.
When straight talk provisioned my sim there were some errors. They were not able to correct them in the computer so have to send me a new sim. It took 4 phone calls to finally come to this conclusion. I will update again if the issue is resolved with the new sim.
As a clarification to the problem. As it turns out it had nothing to do with the screen being on or off. It happened every time my data connection went idle.
I have the exact same issue with my Straight Talk service!
Did you get the new SIM yet? Did it fix the issue?
I have recently switched from Straight Talk to an AT&T 10 GB Mobile Share Plan. Since then my mobile data will randomly be turned off when i'm connected to wifi. It wont turn back on when i disconnect, nor when my device receives (or attempts to receive) an MMS message. Is there some setting i may have accidentally accessed since the activation? I don't have any programs that are capable of changing my device status like that (nor is my phone rooted).
Dont get me wrong, i'm glad something is trying to help me conserve battery haha, but it does get annoying since i only notice it when i get a notification that my device is unable to send/receive a picture message, or that i have no data once i leave the wifi network.
Its just weird since it has only started happening since switching to AT&T Postpaid.

Which ROM are you running? That is strange. It could be something with the APN as well. Are you on LTE or stuck on 3g? Maybe your phone is stuck in one and tries to switch from LTE to H or vice versa? I know when my phone chooses H instead of LTE (I use Cricket, but same towers) it takes quite a few seconds to get a data connection to load, but LTE is pretty quick to load.
It doesn't actually save battery to have data off when using WiFi since that is already happening behind the scenes. Not sure why yours is toggling the setting on its own but perhaps a factory reset would fix it.

Everything is stock. I had a APN automatically assigned from AT&T that caused me to constantly switch from HSPA+ to LTE. I found a better one online and now get LTE most of the time. I never really gets "stuck".Its not that the data isn't loading, its that it is literally set to "mobile data off" on my device, and i have to manually turn it back on in the settings. I wasn't aware an APN setting could change other settings on a phone?

it could be an app doing it, and you not knowing that it can.
My Nexus 5 is running Android 5.0.1 (Lollipop). Unlocked, not rooted. My carrier is Cricket. Here is what happens:
1. If the phone is connected to a WiFi network, I am unable to send text messages. The message will attempt sending for a while and then basically timeout. The app will report that the send failed. This will happen no matter what application I use (Hangouts, Google Messenger, chompSMS...). If I'm on the cellular network, texts send find. EDIT: Actually I'm seeing that's not actually true. Even when I'm on LTE, there's no guarantee messages will send. I can't actually detect a pattern here.
2. I am unable to switch from WiFi to cellular data by turning WiFi off. If I'm on WiFi and I disable Wifi in the Settings panel, the cellular indicator will change to show 2 or 3 bars of service with an exclamation point (!), seemingly indicating that I'm either not on the network or that I don't have data. If I reboot the phone I'll have full LTE.
I first started noticing the issues with text messaging back when I was running CM11 nightlies. Everything was fine and then a few weeks ago it started happening. I figured something had gotten messed up in those builds so I flashed to stock Lollipop but the problem persisted. I flashed to 5.0.1 and the problem remains. I also tried switching carriers from Cricket to T-Mobile, but T-Mobile service was so bad in my area that I had to switch back the next day; I didn't really get a chance to put it through its paces.
I know this is a weird one, so any ideas would be greatly appreciated. Thanks!
I was out in the country trying to get my phone connected to a network as the rest of my family (same plan) had connections with their iphones. Low and behold a new setting shows up in mobile networks that I had not seen before, Access Point Names. My biggest mistake was changing settings in something I knew nothing about but I did and pressed restore factory default. Once I reached an area that had a data connection, it seemed all worked well until I tried to send a text. I soon found out I couldn't send or receive any texts/calls.
I've flashed to stock, updated prl, and nothing has worked. I tried to change apn settings using those from this site 4GLTE, but it proved futile. Now I'm stuck and more frustrated than I was before I couldn't get service.
I feel like an idiot and really could use some help! Thanks!

call your carrier and check your apn setting with them. Fastest and easiest way.
