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] Mobilicity Nexus s 9020t MMS / picture downloading issue

Whenever I receive a text with pictures, it displays a downloading bar. When i click on it, it turns into a "downloading" and nothing happens. I've talked with customer support and they've suggested to add the apn on their site even though the phone already came with it by default. I don't have a data plan yet, so I'm not sure if this might be the problem. Any ideas?

Bump, anyone have this trouble also?
Tried calling for custom support, used the right settings for APN. Still cannot send pictures.

Data plan
Well, MMS does use the data and if you dont have a data plan and you are on prepaid service, you might not be able to use data at all. I'm pretty sure that in Mobilicity's case, the data used by MMS is just counted out of your data plan, its not a sepperate MMS messaging charge or anything like that. Also, make sure you have the correct APN settings, they have it on their website.

I do have the correct APN settings, MOWAP and MOMMS as detailed here.
Mobilicity has MMS for all their plans, regardless of data plan. That was exactly my first assumption that since I did not have a data plan, that pictures were not sending or receiving through.
Anyone have a nexus s with mobilicity experiencing the same problem? I've been calling custom support 6 times now, being asked to visit a local dealer, to a warranty support dealer, to back to the customer support help, and then to the samsung customer support. I've been going in circles, tried using a "demo" sim card in one of the mobilicity dealer place, no fix.

I don't have data plan. i can receive and sent mms
my settings
Name- T-Mobile US
apn- wap.voicestream.com
proxy 216.155.165.050
port 8080
mmsc- htpp://mms.msg.eng.t-mobile.com/mms/wapenc
mms proxy 216.155.165.050
mms port 8080
mcc 310
mnc 260
in order to receive or sent mms you have to check "data enabled "

Well, I got my problem fixed! Apparently you DO need a data plan to receive pictures over mms. The plan states that phones can receive them without the data plan, but smartphones handles pictures differently than regular phones.
I tested out at one of the local stores, and it works. Not sure if like you said, I just need to have "data" on, or actually have the data plan. I'll try the first when my month runs out. Thanks!

Sorry for the bump but i thought it would be better than creating a new thread for the same problem. anyhow, I've recently picked up a nexus s from mobi (with the $25 data plan) and im having problems with the MMS. I usually get a message with the size details, and a "download" button, same problem as you had, it changes to "downloading", then nothing happens.
If i scroll up in the conversation so that the "downloading" button disappears, then scroll down, it's just back to "download." Sometimes (maybe 10% of the time), the message will come up as it should, with no "download" button, the picture just shows up.
ive double and triple checked that the APN settings are 100% correct, so that can't be the problem. I manually updated to the official release of ICS 4.0.3 (from this thread) last night, but it didnt work before either (came stock with 2.3.4) Sorry for the life story, but thanks for any help.

[Q] lg g2x on straight talk

Let the yelling begin. Just got my G2x from ebay
Used the Nokia E71 sim that I already own
Straighttalk tech support said I need to get a new sim and phone number.
ATT said I do not need a new sim. SO i came here
Phone works, texting works, WiFi works after setting apn= ATT.mvno
sw=p999-V21e
FW=2.3.3
Baseband M6600A-Acautnz-2.0.9720T-1

any ideas.

so if everything works, whats the problem?

the problem is no data . no internet

That would be a sim issue. You may need an unlock code to have access. Other wise check your vpns
Sent from the last drop of EaglesBlood: 4.0.4 G2x

Well alright, I just read phone works text work and so on... try putting in the apn's in??? I just googled this try looking more if it doesn't work for you. Other than that maybe SIM???
http://www.howardforums.com/showthr...w-the-proper-APN-settings-for-Android-Devices

unlock code
I think the phone is unlocked. That is they way it was sold . Says t-mobile on it but when calling or txting displays att ( that is the nokia e71 sim ), and the the att.mvno that I entered .
How do I check if it is unlocked?

If its unlocked it should all work. http://www.taniwha.org.uk/gprs.html Try looking through here. US is almost all the way at the bottom. Not sure exactly what your using. Not sure if you need the sim carrier or the baseband carrier.
Edit: oh, and if you have access to the phone when you put your sim card in, you said your making calls and sending texts. Yeah, your phones unlocked. The internet thing though is a little weird.

straight talk g2x
It could be the way straighttalk connects to internet. The sim from E71 nokia works with I phones and straighttalk can't find any info why it wouldn't work with android. Thanks for your input.

Lg G2x on straighttalk setup that works
Here are the steps I used to get MMS working on Moto Backflip with Android 2.1
First download Apn Backup and Restore app from app store, and delete all existing APNs. Then manually enter APNs. In android you must have 2 apns setup for mms to work (at least in my case).
Here are my settings:
Name
HOME
APN
att.mvno
Leave everything else alone EXCEPT the bottom selection that says:
APN type (here you must enter the following)
default,supl
Then save, next choose to add another APN
make it look like this:
Name
MMS
APN
att.mvno
skip down to
MMSC
http://mmsc.cingular.com
MMS proxy
proxy.mvno.tracfone.com
MMS port
80
skip to:
APN type (enter the following)
mms
THEN SAVE
You will see that only one APN has the option to be chosen, that is ok, Just choose the one that is able to be chosen.
Now go back to Homescreen and then reboot your phone.
This works for me, hope it can help you. I tried a hundred different ways and this was it. Capitalization is important, and the APN type was the trick.
GOOD LUCK and let me know if it worked for you.

it works 2g where I am now but I am in

Did you get the data to work? I've been considering going to ST. I've had them before, and for a prepaid company, had really good experience with the service in my area. The same can't be said for Tmo

Lg G2x on straighttalk setup that works
yes it works. The configuration I used is posted a few days ago. The speed for connection shows 2g. Other than that it works well. I am looking for the code to get 3g now. If you read the code above you will see the words tracfone. That is a 2g network ( I think ). I think I have to change that.

Well it's all the same company. Not sure how they handle that. I wonder if it might have something to do with using the SIM you used, (which would make ST right when they said you need a new one.) In any case, I'll just be buying a SIM from them to use on my phone, so maybe it'll work out fine. Unfortunately, I'm still under contract at the moment, so it may be a little while longer.

Straight Talk works well on the default Tmobile ROM, but I just upgraded to Eagles Blood and the T-Mobile SIM settings do not work at all on Straight Talk (for MMS+Internet). Does anyone know of a fix?
These are my settings:
Name: Straight Talk
APN: wap.tracfone.com
Port: 8080
MMSC: http://mms.tracfone.com
MCC: 310
MNC: 260
Thanks!

Yeah my phone works fine using the stock LG G2X, but won't work once I load a custom ROM on straight talk (or SIMPLE mobile).

Strange APN [email protected]

Hi all
As a T-mobile UK customer I have been finding that I lose internet on my phone every 6 or 7 days, typically lasting for about 6 hours.
During my last converstaion with support I mentioned that i had the following in the APN settings
[email protected]
They seem to think that it might be a Tmobile USA profile and hence the problem (how the wrong APN could work for 95% of the time is beyond me).
I did take the handset to the USA last year but did not have data roaming turned on. Does anyone know how i ended up with the wrong APN? A quick google search returns no results for the APN listed...
I have since manually changed the APN and things seem ok (for now).

Whoops.... I have just found out where the the APN settings came from.
In an attempt to get my MMS working I just ran the HTC Connection Manager. For the first time in 1.5 years my MMS is working but I have noticed that my new APN settings say [email protected]
So it seems that HTC use APNs that T-mobile UK are not familiar with? Annoyingly I have no way of viewing the new APN or editing it
Does anyone know which settings the HTC connection manager uses? I am concerned that although MMS is working, if my internet connection goes down again, the UK helpdesk might just shrug their shoulders and pass the buck to HTC, who in turn will pass it back

Ok so I spoke to HTC UK today, they told that they have no way of finding out what APN their app uses, they suggested that I use the generic T-mobile APN that they have on their system, which I did and the MMS stopped working again.... so I ran their app and alll is fine again (for now).
I guess that I will have to try to email HTC. It is rather annoying that MS decided that customers shouldn't be allowed to see existing APNs.
I do have a dev account, tbh I only subscribed so that I could get mango early, if that means that I can sideload something that will show me the APN in use then please feel free to point me in the right direction.
Cheers

v20 says "mobile network unavailable

First time poster and a real newby when it comes to tweaking phones.
I have an unlocked LG V20 which I purchased (and really like) from T-Mobile. I am trying to use it with Consumer Cellular. I have gotten it to work sometimes but it connects very seldom.
I had to set up the APN settings manually which seems weird but like I said, it works - sometimes.
Currently, I cant seem to send texts or even call anyone. The phone says it's registered on the network.
I was having an issue with it de-selecting the APN settings I had made (and saved) for Consumer Cellular. As it was a T-mobile phone, I figured it was trying to go back to the T-Mobile APN so I figured out how to delete the T-Mobile APN. I also deleted all other APN choices except the one I had made for Consumer Cellular. Now it seems to keep the CC APN selected but only for a short time. After awhile, it will de-select the APN so there is no APN selected at all.
Now it cant make calls at all
I am also getting an "er082" error (red phone icon) regarding WiFi calling.
Any help would be much appreciated. I really like this phone and would like it to work
Thanks,
Jim
