No 3G icon or data connection

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*

[Q] Switch from WIFI to 3/4g delay issue?

When I go from WIFI to 3g/4g, it takes up to a minute for the check mark under H to disappear... during this period, apps can't connect to the Internet (and I get a connection failed error message) It is merely a hiccup but I wondered if this is a common issue and if there's any fix. It does this from all wifi connections I've tested.

I also have problems connecting to market when switching to wifi on occasion. No issue connecting to market on 3g.
I am on stock rooted ATTn1 rom.

OK, I stumbled on what seems to be a fix.
I went to APNs. The only one listed was MEdia Net.
I hit the menu button and pressed Reset to default.
It created a new locked APN called MMS. MEdia Net remained selected.
I exited APNs and went and turned off WIFI. 3g data immediately came on (up and down arrows) with no delay.
Anyone understand why this worked? Hope this helps someone in the future.

Thunderbolt not connecting to 3G in non-LTE 4G areas?

After doing a manual root, the Thunderbolt connects to LTE fine but when there is no LTE, the 3G won't connect and the phone doesn't receive data.
Advice?

Try checking to make sure you are not in LTE only mode. Dial *#*#4636#*#*, select phone information, scroll down and go down and make sure you are on the CDMA + LTE/EvDo auto option and not LTE mode.
If that doesn't work, try downloading "reset connections" from the android market and running that app when you enter a 3g area out of 4g range. It may be a handoff issue from 4g to 3g towers.

##778# hit dial, edit mode, password is 000000, modem settings, Rev. A, change to enabled, instead of eHRPD, hit menu, commit changes.
try 3G again.
I assume like me, you are in a section where Verizon's Hybrid Network isn't working, and so you must tell your phone to revert back to their regular 3G network.

We have 4G in Pittsburgh, but there's a spot in Squirrel Hill that I go through on the bus in the morning where I drop to 1x, and I'm fairly certain that there is 3G there. However, there are other areas I've definitely seen 3G. So, it seems a little mixed. We're definitely early adopters of this new network

The fix
Phone ##778, edit mode, 000000, modem parms, REV-A change from ePHRD to enabled, menu, commit, reboot, problem fixed.

seems to have worked for me. I was having a problem with syncing too, hopefully this fixes that as well. Thank you!

Not to familiar with TB verizon, but friend bought his TB and I saw there was 4GLTE on it, and now nothing, no icon not in wireless networks, nada!
What is this "fix" for?

No 3g signal

I'm on bamf soab 1.03 and I dont think anyone else is habing this problem but I'm wondering if anyone knows how to fix this issue. When I get 4g signal the phone will use it but won't use 3g. It drops out of 4g and then just stays without data. So basically its only using 4g or else its just not connecting to 3g. There is no data problem in my area because people I live with are getting 3g just fine....any ideas?

Menu > Settings > Wireless & Networks > Radio Info > Change LTE only to CDMA/LTE mode
if you don't have the radio info option there, download LTE toggle from the market and do the last step.

heh. i tried out the new 1.03 and market just kept crashing on me(even after force stopping/clearing data) and uninstalling updates. so i just thought "to hell with it" and switched back over to shiftao3p

No such setting as LTE only. And my phone has always been on LTE/cdma so its not that I already checked that. I'm not a noob user.

do you have EHRPD on under modem settings in ##778? It should be. Past that I sometimes reset if it has issues locking on to one and that will resolve. That's all for my ideas, though I'm still on SOAB 1.02

This is what i was going to suggest. Here's some information that might be helpful. I've found that with the network testing and stuff the past few weeks in my area, sometimes revision a enabled is better, sometimes eHRDP works better. Try switching revision A and see what it does.
Try dialing ##778# on your phone, hit call if you need to.
Choose edit mode
Password is 000000 (six zeros)
Choose modem settings, go down to revision A, and change from e HRDP to "enabled"
Press menu and commit modifications, phone will reboot.
After it settles you may need to go to *#*#4636#*#* and choose phone info then change your preferred network settings to get a solid signal.

I was messing with it last night and seems that the issue is fixed if it happens again ill follow those steps. I'm a pretty advanced user but I'm not so familiar with those settings so thanks for the help

I'm running a version of 2.11.605.3, de-bloated and rooted.
I lost 3G on October 21st. I would either get 4G, or nothing. On occassion, I would get 1x. Selecting CDMA only gives me NO data
If I change the REV-A option under the ##778# menu from EHRPD to enabled, the 3G comes back and the toggling between 3G and 4G works fine.
Switch back to EHRPD and 3G goes away. Seems like the problem is with EHRPD. I don't know why all of a sudden it stopped working correctly and I don't have enough tech skills to identify the possible cause.

VZW has had trouble with their Data network the last two weeks, could be a VZW problem. I have not had any 3G problems on my phone and I am running SoaB v1.03 on my phone.

Software: Android 5.0.1 Skydragon M8 v2.0 Sense 7
Many people have posted issues with LTE where their cellular signal was fine for "2G" functions like calls and texts.
I'm having the opposite problem. After leaving airplane mode (landing at an airport today), I have a "No Service" message in the status bar drop down (notification tray), and the Settings>Network information page shows "Not Registered." However, I do have an IMEI (see details below). However, LTE data works perfectly fine.
I've obviously tried changing the settings in Settings>Mobile Data (preferred network to Global / LTE / LTE/legacy 3GPP mode) connection type global/auto/LTE/etc), to no avail. If LTE is connected it works flawlessly, but I cannot make calls or texts, and show not registered on the network. Data roaming is set to deny, but even allowing roaming does not change the situation.
Before this happened, I HAD gone through all the XTended Settings, and even 'looked' at (but did NOT change) some advanced settings pages, including the 'hidden' HTC network info page ( *#*#4636#*#* ). Again, however, I didn't change anything -- unless by accident?!
Does this sound familiar to anyone? Anyone know if I may have inadvertently changed something and can change it back (a setting that would persist in the hardware through NANDROID restores and factory resets...). Or, any other advice to restore the cellular service connection to normal?
I've tried a full NANDROID restore (multiple times) to a working copy, and a factory reset. I have limited access to a PC since I'm traveling, so re-flashing the VZW firmware or stock recovery or lollipop/verizon RUU would be challenging.
I did spend a good 45 minutes (at a library, my only PC access!) searching the forums and web, but to no avail.
Settings information:
OPperator Name: Verizon
Signal Strength -114 (I've had better but still have the same issues)
Mobile Network type: LTE
Service state: In service
IMS service state: Not Registered
Roaming: Not Roaming
Phone Identity page:
IMEI shows up (15-digit number...how can I verify I didn't mess this up?)
Phone Number is correct
IP Address: 100.66..... (looks good)
Any help is GREATLY appreciated!

Same here
I'm having the same issue. When i try to make a call my LTE bars drop to nothing and it says call failed no network available. Any ideas or help would be nice. I was using venom rom as well. I'm currently trying to flash the newest RRU to see if that resets things. I'm wondering if it somehow my sim card. I took it from my droid turbo. I've made sure to turn off advanced calling on my VZW account though.

I had this same issue, running from ruu then rooted. I didn't noticed until I started seeing voice mail notifications but never heard the phone ring. When I tried to dial out I got the immediate call lost message. I couldn't figure what was causing it so I just did a reset. I made sure not to restore any systems data from prior to the Lollipop upgrade. At this point everything is working, the only thing I haven't installed yet is the xposed framework and sense 6 toolbox.

What kind of reset did you do? I know my issue is slightly different, but I did a full RUU-flash yesterday (latest lollipop version) and still no luck. Unfortunately I'm out of the country now and access to a computer is limited, and I don't even have a SIM card yet to check if cellular service would work anyway.
I do intend to do a flash of the stock recovery and radios once I have the time and access, but that may be a while...
Still, I'll keep checking this thread to see if anyone posts any other options

Just go into settings and to Backup & Reset , this will return your phone to a fresh install and remove all non bundled apps.
Before doing the reset try going into Settings then Call then change Preferred Network to Global, or toggle from LTE then back to Global.
