Can't Connect to AT&T Network.

My Captivate can read the SIM Card, but I can't connect to the AT&T service.
I go to Settings > Wireless & Network > Mobile Netoworks > Network Operators > And select AT&T, but it says "Your SIM card does not allow a connection to this network."
On Perception 9.5, When I do the same thing, It says "Unable to connect. Try again later."
I flashed other ROMs and they all do the same thing.
Help?

Are you using an AT&T sim that has a data plan enabled?

Yep. 3G, Calling and SMS was all working before.

Have you manually checked the apn settings?

Did you flash a new rom recently? Maybe the modem isn't playing nice.
If nothing else, go get a new sim from the local store and see if that fixes it.

Yeah, I flashed multiple roms (Perception, Doc's, Darky, GingerClone...). They all do the same thing.
I guess I will just head over to AT&T and get a new SIM.

[Q] No Data Connectivity after Overcome Flash

I just flashed Overcome 3.1 on the my ATT Galaxy Tab 7. The rom is super smooth. Everything appeared to go flawlessly however once completed I was unable to establish a proper data connection.
Its shows 4 bars and says connected to ATT as the "Network" under the Status menu. However the "Mobile Network State" is listed as disconnected.
If I go into the Mobile Network Settings. Under Network Operators ATT is listed under Auto Connect and if I rescan it accepts the choice and then says Registered on Network.
I cannot browse the internet. I called ATT and they were able to send me a SMS so there is some sort of connection. We could not troubleshoot any further as there systems are down.
I did a vanilla Overcome Install. Is there a post install step that I need to do? I seem to remember a similar issue with my Dell Streak that involved modifying my APN settings. Here are the APN settings for the device. (these are the Overcome defaults i believe)

I read this on this forum somewhere, and has always worked for me when reflashing. This is ONLY for the Pay as You Go data service to my knowledge. Your mileage may vary.
I changed my APN to the following EXACTLY:

I always get a connection this way. No MMS, but I don't use it anyway, that's what my phone is for.

The "broadband" apn is only for the sim card that came with a stock at&t tab, and not for the sim cards we all took from other phones.
For the former phone sim cards, wap.cingular or isp.cingular apn's.
The setting should be to "auto".
You didn't mention your modem - baseband.

Baseband: I9000UGJK3
Modem: I am not sure how to verify this on the device (Im an n00b). I did follow the wonderful guide on Team Overcome and it recommended using "JK3 Modem" During the install. I would assume this is what I am using. How can I verify this?
PS. I wapped in my phone SIM card and everything works just fine. I can even make phone calls!

This did the trick! I used these settings with the replacement SIM card they gave me at the ATT store...

Good job. The baseband is the modem, so you are using JK3 - that's the best choice for you.

Question: No DATA on US ATT Unlocked Eurospec

Just got my Note straight from the UK, unlocked. Been on the phone with ATT about 6 times. I can send and recieve calls, texts - but no DATA. They can't seem to figure out why it will not pick up the ATT Data Network. Sim, EIN all linked, but no joy.
I am a noob, sorry - any ideas. I hate to send the phone back.
Any ideas ?
Update - Funk2641's response below (no APN was entered) - fixed it the issue.
Still, ATT would not give me a 4G smartphone plan - even though the H+ shows up next to the clock ? Initial Speedtests look like the same as my Infuse, Atrix and 4S.
Thanks everybody (Funk2641) for your help ! I hope this thread saves some agony for many as this phone is hitting the states. Don't know if I will tread in Eurospec for the Nexus, as I will want to hold that one in my hand first.
Also, this is a great phone - speed, battery life and the screen is fantastic !

No, I will give it a try.
Thx.

please keep posted.....I'll be on Att Friday

I will follow this thread since I will also switch from T-mobile to AT&T.

I too have the same issues. I actually used a few different apns and got edge to work poorly, I sighed and told myself ICS would fix it all up better and to just enjoy the extra battery life of 2g now, God I hope a get this cleared up

Technically, the Note is just a big SGS2. There's no reason on the phone side you should be having a problem using the Cingular APN. I'm using a ISGS2 and a UK 3G Tab 10.1 on AT&T with no problem. It's either something with the provisioning of your account or your Note may not have the right bands (Asian?). The latter is unlikely if you ordered it from the UK. Try reseting the APN to default under network settings. Also, if you're on a legit 4G plan there's a specific APN that you can find on the ASGS2 forum.

Here is another APN that works, I had the same issue
For APN settings use the name ATT and then for APN the word phone. Leave everything else blank-what is needed will get filled in automatically. Click the APN when you finish adding it and the radio button turns green to indicate it is working. The advantage to this APN setting is it gives you clear access and data speeds are not limited by ATT.

Those apns didn't work and I too a would doubt my phone bring the Asian version,.this version of gingerbread has the option to suspend my data network from holding down the power button maybe the software isn't...... I don't know I have no clue but my apns are normal but when's search they don't come up
In the list automatically so something a wrong
and I came from a hspa+ phone so my plan is already to go, I called to double check

to op, glad you got it straightened out...who did you order from and how much?

I cannot connect to at&t. under APN i get "no items" and cannot get to a place to enter apn settings.
"use packet data" is selected
network mode is gsm/wcdma (auto mode) is selected
"search networks shows select automatically, at&t, and at&t. I have tried all three
i get regestered on network, but still will not connect help!
I am on the iphone plan with unlimited data, worked just fine in galaxy tab original 7"

i tried using funks apn settings and i still have nothing, i came from an atrix where i always got H+ and now here are me speeds, my speed test was done in detroit, i live in NJ my ping was 317, U 144 kbps D 155 kbps, i have no idea what is wrong with this phone but att can get going on it, i called and they have nothing for me!!! i dont know what to do

What plans are you guys, please?
(Anyone on month to month $50 unlimited?

There are two different APNs to use depending on what data plan you're on. If you're using a MediaNet or Data for non-Smartphones plan (3G) you need to use the Cingular APN. If you're on a legit 4G plan you need to use the special APN for 4G phones. If you reverse it, you'll get no data. For those of you on the 4G plan, go in to the APN settings. When you press menu, there's a reset to default option. It should pull the 4G settings down automatically. If you're on a 3G plan don't do this and instead manually enter the below settings. If you do this correctly you should get data. If you have a quad-band phone and still can't get data it's something with your account settings and not the h/w.

[Q] Really naive question about the HD and SIM cards

My employer provides me with cell service and to date hasn't cared if I use the Blackberry they provide or put the AT&T SIM in a personal phone. Provided I don't hassle the phone support staff with problems I created, of course. I've used the same SIM in 3 different phones over the past year and haven't had a single issue. I just got a used Atrix HD and discovered that it uses a micro-SIM instead of a regular size. I used a template and cut it down to size (and I think I did it correctly). I put it in the AHD and the SIM is recognized as AT&T but I cannot get data service. On first use with the bone stock ROM, I got a text message and was able to reply to it. Because I have no intention of staying stock, over the past two hours I've done the following:
Rooted
Unlocked bootloader
Installed the ATT-US_BuildA ROM
Wiped that and installed CM10.1 nightly from 05/16
I've not been able to get any data service and now the status is 'In service' for Service state, 'Disconnected' for Mobile network state, and 'Unknown' for Phone Number. Even after cutting down the SIM, I can put it back in my Blackberry and voice and data work just fine. Thus I know the SIM is healthy. Questions:
Is the mini-card slot in the AHD that finicky that a mm difference in card size will dork it up?
The SIM is several years old now. Is it obsolete for the AHD (not withstanding size)?
Are there any settings in the phone that I'm overlooking? The eBay seller was in the US but I do not know the original location of the phone.
Thanks for any advice you can provide. Unfortunately, I can't take it to an AT&T store because the account is my employer's. And my employer really doesn't want to deal with my issue that only exists because they were nice and turned a blind eye to me.

maybe you need to change your APN settings go to settings and under wireless and networks select "more...."
then mobile networks and then access point names select the menu option in the top right and select "New APN" and enter the info below

Wi-Fi Calling not working Metro-PCS

I've tried to ask this on reddit but I could not get any help. I have seen a thread on the nexus 6P but not for the nexus 6. WiFi calling does not activate, I have metropcs but I've seen people have WiFi calling activated on metro. It does say IWLAN on sim status but I can't make calls or texts. I have tried many WiFi networks and have flashed the stock image but still can't connect. E911 address is updated as well. http://imgur.com/a/6ZP9h I am on chroma 12/10, i manually flashed 6.0.1 stock, i also used the tmobile lollipop image for wifi calling and not luck, any help? Thanks

I recently got a Huaweii Nexus 6p about a weak ago and this was the one feature i needed the most due to poor reception in some parts of my home. After many days so searching xda, t-moble subreddit, and other help forums. I also made many calls to customer service and still getting no result. As of the other day i can confirm that I've found a solution.
1. Submit your e911 address to metropcs. You can the my metro app from the playstore or call customer service and give it to them so they can put it in the system manually.
2. Go into the apn settings and maually delete each default metro pcs apn one by one. After deleteing them you should notice that the apns will default to showing t-mobile's apn settings. (Ex: T-MobileGPRS, T-Mobile IMS, T-Mobile MMS)
3. Click on the first apn that says "T-MobileGPRS" that is the setting we will edit. The other apns you can leave as is.
4. Once in the T-MobileGPRS setting change the Name from T-MobileGPRS to "MetroPCS".
5. Change the the APN from fast.tmobile.com to "fast.metropcs.com" . Leave all other settings as is and then save the changes.
After that give it a few minutes then you will notice it says "T-Mobile Wifi Caliing" make a test call and you should see in the dialer screen "wifi calling". From the there you will be good to go!
** I can also confirm that this solution also activates VoLTE and data and mms also work with not issues at all!

Alright looks like you have the same setup i did. I stumbled upon this new configuration after the original solution I had posted stopped working. So with your current apn settings
1. Delete all the the Metro PCS 260 apns.
2. From there you should only have the default T-Mobile apns that list T-Mobile GPRS, T-Mobile IMS, T-Mobile MMS.
3. Edit the "T-Mobile GPRS" apn and save the following configuration:
Name: MetroPCS
APN: fast.metropcs.com
Proxy: <Leave in Blank>
Port: <Leave in Blank>
Username: <Leave in Blank>
Password: <Leave in Blank>

MNC: 260
Authentication type: <Leave in Blank>
APN type: default,supl
APN Protocol: ipv6
APN Roaming Protocol : ipv4
Bearer: unspecified
MVNO Type: None
from there save this apn.
4. Create another apn to the list with the following configuration:
Name: MetroPCS 260
APN: fast.metropcs.com
Proxy: <Leave in Blank>
Port: <Leave in Blank>
Username: <Leave in Blank>
Password: <Leave in Blank>

MNC: 260
Authentication type: <Leave in Blank>
APN type: ia
APN Protocol: ipv4/ipv6
APN Roaming Protocol : ipv4/ipv6
Bearer: unspecified
MVNO Type: None
Save this apn when done.
5. From there you should have this list of apns: MetroPCS, MetroPCS 260, T-Mobile IMS, T-Mobile MMS.
Make sure the MetroPCS one is selected( The 1st in the list)
Almost forgot. To enable SMS texting over wifi:
--Go to Dialer; then dialpad
--dial *#*#4636#*#*
--Phone Information
--Turn on SMS over IMS.
From there if you once your done restart your phone and connect to a wireless network. And wait a few minutes then it should work from there. I used this setup and i can confirm that both wifi-calling is working & VoLTE. Let me know if this worked for you.

1. Delete all the the Metro PCS 260 apns.
2. From there you should only have the default T-Mobile apns that list T-Mobile GPRS, T-Mobile IMS, T-Mobile MMS.
3. Edit the "T-Mobile GPRS" apn and save the following configuration:
Name: MetroPCS
APN: fast.metropcs.com
Proxy: <Leave in Blank>
Port: <Leave in Blank>
Username: <Leave in Blank>
Password: <Leave in Blank>
Server: <Leave in Blank>
MMSC: <Leave in Blank>
MMS proxy: <Leave in Blank>
MMS port: <Leave in Blank>
MCC: 310
MNC: 260
Authentication type: <Leave in Blank>
APN type: default,supl
APN Protocol: ipv6
APN Roaming Protocol : ipv4
Bearer: unspecified
MVNO Type: None
from there save this apn.
4. Create another apn to the list with the following configuration:
Name: MetroPCS 260
APN: fast.metropcs.com
Proxy: <Leave in Blank>
Port: <Leave in Blank>
Username: <Leave in Blank>
Password: <Leave in Blank>
Server: <Leave in Blank>
MMSC: (add in the http:// before)mms.msg.eng.t-mobile.com/mms/wapenc
MMS proxy: <Leave in Blank>
MMS port: <Leave in Blank>
MCC: 310
MNC: 260
Authentication type: <Leave in Blank>
APN type: ia
APN Protocol: ipv4/ipv6
APN Roaming Protocol : ipv4/ipv6
Bearer: unspecified
MVNO Type: None
Save this apn when done.
5. From there you should have this list of apns: MetroPCS, MetroPCS 260, T-Mobile IMS, T-Mobile MMS.
Make sure the MetroPCS one is selected( The 1st in the list)
Almost forgot. To enable SMS texting over wifi:
--Go to Dialer; then dialpad
--dial *#*#4636#*#*
--Phone Information
--Turn on SMS over IMS.
From there if you once your done restart your phone and connect to a wireless network. And wait a few minutes then it should work from there. I used this setup and i can confirm that both wifi-calling is working & VoLTE. Let me know if this worked for you.

Ok so I tried this and then I had no data connection. After some time all I had was H. I then tried enabling wifi and putting on airplane mode with wifi enabled.. phone said connect to a network to make a call. To get my data and mms back I had to remove all the APN's and reset to default. I left the three tmobile ones there and added the mmsc (http://mms.msg.eng...) to the Metro 260 apn and now I have LTE again and my MMS is working as well as texts.
I guess its because I am on band 4? If you download LTE Discovery what band does it say you are on? This is weird at least I had Volte on the nexus 6 with the same sim card on metropcs.
