At&T Apn not working on xperia x10 - XPERIA X10 General

Hey there
I am in a weired situation that I was expecting. So here is how it all went down.
- I have an Iphone, however Bought an Xperia X10 from Rogers wireless store and got it unlocked.
- Brought it over to California and put my At&T sim in it (which has Iphone data plan and all that jazz)
- Set up the following APN details
Name: AT&T
APN: wap dot cingular
Proxy: leave blank
Port: leave blank
Username:WAP at CINGULARGPRS.COM
Password:CINGULAR1
Server: leave blank
MMSC: mmsc dot cingular dot com
MMS Proxy: wireless dot cingular dot com
MMS Port: 80
MCC:310
MNC:410 (note. this could also be 310, 41 or 15)
APN Type: leave blank
- After setting up the APN I could see the 3G and the data going back and forth. Content with that. I took the sim out and started using Iphone as usual.
Today I decided to make a final switch to Xperia x10 and put the sim back in the X10 and lo and behold, It wont pick the data connection at all. I checked the APN.. it was the same as given above, tried restarting it but no love.
After couple of hours, i was messing around and it suddenly starting showing E for Edge but no 3G (which i used 2 days ago for half a day). Even the Edge is sporadic, comes when it feels like paying a visit... and goes away when feels like it.. i had booty calls more reliable then this connection
I am pulling my hair out because I am not sure what is going on here. Even though it seems like Edge is connected, but its so slow that I may end having a couple of kids before Facebook will update. No sign of 3G at all .. which by reading through the threads seems like is an easy task for rest of the guys !!
Can you please help me with whats going on. Am I the anomaly ? Did I miss something (all i did was to setup APN nothing else), do I need to some other settings that I am not aware of ?
Any help that you can provide will help me a lot, I dont want to give up just yet ..

the phone can set the settings for you automatically. there is an option for this. i forgot the exact steps but you can find this in the Mobile network settings.

Settings -> wireless controls -> mobile network -> automatic something

Might not have that option if he didn't debrand his x10. Just go to sony ericsson site and support page. Pick support for x10i and give them your info and they'll send you the settings.

You might need to have the smartphone data plan provisioned on your account instead. I am pretty sure the iphone is a different plan in their billing system based on our company bill I review each month.

I just brought my x10a rogers locked phone today and I set up APN using information above. I am able to get 3g data. I did call AT&T and change my data service from iphone data to a Non AT&T smart phone data. I dont think you need to debrand the phone because I didn't and the phone works fine!

can not send MMS on x10a on at&t apn settings
I also have an unlocked Rogers X10a, and I am currently using it with the $10 Media Net data plan from AT&T. Everything seems to be working except picture messaging.
Here are my current APN settings: (btw my phone is NOT debranded)
Name: Media Net
APN: wap.cingular
Proxy: wireless.cingular.com
Port: 80
Username: [email protected]
**Password: CINGULAR1

MMSC: mmsc.cingular.com
MMS Proxy: 66.209.011.032
MMS Port: [blank]

MNC: 410
APN type: <not set>
**Password is case sensitive
Does anyone know how to get the picture messaging to work?

I have resolved the issue by debranding the phone.
Once you debrand the phone, the automatic internet setting button becomes enabled. All you have to do is to tap it.. and every thing gets updated with the proper setting including MMS

Can you point me to which thread you followed to debrand your phone? I've been to 3 different threads, including the one on here, and the one on xperiax10.net
According to http://forum.xda-developers.com/showthread.php?p=6571098 the new sony ericsson pc companion will no longer work.
Any help would be greatly appreciated!

Glad to hear that you're still using the Media Net data plan instead of being automatically switched to the smartphone data plan. I'm currently using an N97 and have been thinking about upgrading the x10a from Rogers, but have been hesitant because I didn't want to be forced into the new 2gb smartphone data plan.

Your brother made an excellent choice by not getting an iPhone or any other at&t smartphone. The advantage of buying an unlocked and/or unbranded phone outside of at&t is that you can utilize the $15 media net ($10 w/ family text) data plan. Since our IMEI number is not registered in the at&t database as a smartphone, we are not required to use at&t's $30 data plans. I had the $10 data plan for years and always bought phones from Canadian networks like Rogers. Lastly, by unbranding your phone, you now have the ability to get updates from Sony Ericsson earlier. Traditionally, updates that are released by the manufacturer have to be approved by the network carrier before final release to the consumer. With an unbranded phone, you get the update without carrier approval. For me, I can't wait for the Android 2.1 update from Sony Ericsson to come out at the end of this year.
I hope that helps, if your brother can't send picture messages, make sure to unbrand his phone.
Good luck!

I think that's more along the lines of debranding it from x10i to x10a or vice versa!! just stick to debranding to whatever version you have.. (x10i or x10a)

I debranded my Rogers X10a (White) to X10a Generic America BR (R1FB001) listed on the esato debranding tutorial. "Automatic Internet Settings" is still disabled on the phone and the manual APN settings for AT&T only helps with data connection but the MMS still doesn't work.
So, wondering if anyone can backup their AT&T APN settings with MMS working using the free app "APN Backup & Restore" and post it here we can all use. I would appreciate if someone can email me the file if they can't post it here. I can PM my email if you can do.
Thanks.

Quick question, you said you use non smartphone, data do you get 3G speed? can you post what kind of speed you getting using Speedtest.net app? When I got my x10a I called At&t and they changed my data from iphone to non-smartphone and I didnt get any data at all for some reason. They have to change my data service to a smartphone for me to get 3g service. Thanks

To anyone on the medianet plans with at&t, even if your x10s imei isn't in the database you could be put on a smartphone data plan automatically. I used to work for them (before my job went to Manila without me) and i would get multiple calls each day regarding this. I think they can notice differences in the way data is accessed. Just a heads up for all the at&ters on this forum

Tell AT&T that you changed your phone. They will need your phones IMEI number activated on their side. BTW, make sure you have smartphone data plan if you want the full featured browsing, etc. I don't know if regular data plan works on x10a (mine didn't.. I use to have blackberry which also has 3g/edge but doesn't support full featured browsing, etc.)
Check your phone info service by pressing these buttons in sequence (L = Left, R = Right): L - R - R - L - R - L - L - R
Check Model Info. If it says ( X10a, Generic GLOBAL, Generic ) use the Auto Internet settings in your phone. If it says ( X10a, Canada, Rogers ) use the Sony Ericsson OTA wizard -- (sonyericsson(dot)com/ota/wxhtml/otawizard)
Hope that helps.

I have uploaded a copy of my MMS settings per your request. If you have the chance, head over to X10 development forum, and take a look at the x10 Rooting Guide. I think rooting your phone can also help you debrand it.

[Q] Focus + network type changing

Currently experiencing "hiccup" in internet/data experience with my focus. If phone is not in 3G+ mode, i get no data.
Can someone confirm my theory;
Situation:
Purchased Samsung Focus from rogers, thus rogers network profile (preset network setting for data usage such as MMS or internet).
Unlocked and stuck in bell SIM. can send/recieve calls, and txts, use data (internet, marketplace, weather updates, etc) if phone is in 3G+ mode (seen by tapping near top of screen). Can not use MMS
Presumable:
1)Focus was initially programmed to work on Rogers network.
2)Focus/Rogers, have a GPRS & EDGE capability
Theory:
Focus is programmed to use 3G radio for data (which is more widely accessible, & consumes less power), until detects 3G+/HSPA network and switch to that HSPA radio.
Since bell does not have a GPRS or EGDE network, when phone tries to receive data through 3G radio, it get nothing because no GPRS or EGDE network.
Is this possible, can phones change network they're using?
Theorized Solution:?????
Since Bell has 3G+ network,and they offer LG quantum. Could LG quantum be initially programmed to only use 3G+/HSPA, therefore anytime data is requested it activates the 3G+ radio.
If this is true of the LG quantum, could this be programmed into the Focus as well.
Thus i ask the community is this possible and how to implement solution?????
Sidenote:
I know the easiest solution would be to change to Rogers, however, Canadian provider fees are ridiculous (i'd be incurring early cancellation fee + a new restrictive costly plan from rogers) and there are others which don't have a choice but to use bell, and should have the freedom to choose a device of there choice with a little work.
I'm hitting a similar issue on Fido. The cell side works, and data only works if I enable data roaming. I downloaded the Network Profile app, but it won't let me get anything as it tells me "The application can't be launched with your mobile operator."

I think in your case it's just a matter of adding a APN.
Follow the instruction in the follow thread:
http://forum.xda-developers.com/showthread.php?t=843517
a search for "FIDO APN" on google, and i found this;
FIDO
Name: fido internet
APN: internet.fido.ca
Username: fido
Password: fido
APN Type: default
Leave All other Settings Blank
MMS
Name: fido mms
APN: mms.fido.ca
MMSC: http://mms.fido.ca
MMS Proxy: 205.151.011.013
APN Type: mms
Leave All other Settings Blank
That should get your data working, and you wont be incurring roaming charges.
Other then that, let me know if your having a similar issue to above, i don't think you should as FIDO is a pure GSM network from day one so it'll have GPRS/EDGE/HSPA
MMS
Interesting the various issues people are having with connecting to different networks...doesn't seem to be a one-size-fits-all issue/solution.
In my case, I got a new Rogers sim card (unlocked AT&T branded Focus from Expansys), put it in, updated my APN info, and I have voice and data.
BUT, I have no texting/messaging ability! I know others have listed the MMS settings for Rogers, but the Focus seems to only allow adding *one* APN setting. No clue where the MMS settings can be applied.
Other friends who have Rogers sims were able to put it in their Focus and had no problems at all with texting, internet, etc.
Anyone have thoughts on this issue, please respond.

The instructions appear to be for the LG device, not the Samsung Focus. The code doesn't get me into any factory menu. The diagnostics screen just sits when I type in the code. I downloaded the Network Profile app but it errors out saying "The application can't be launched with your mobile operator".
Facepalm
OMG, I'm an idiot!
So apparently Rogers requires 1+area code for sending texts? Telus didn't...*sigh*...
So yes, I have texting ability (haven't tried MMS though).
Samsung's response:

Now that this issue got publicity lets see how long they keep up this attitude?
UPDATE:
COuld it be MS to the rescue?

Not much to add other than I'm in the same situation as reaver_shadow. Bought from Rogers, unlocked it and put in Bell SIM card. Everything works except MMS and data if not on 3G+ (will work when '3G' is displayed, but I guess it's borderline). Tried playing with option *#2263# in Samsung Diagnosis (##634# + Dial), but does not fix the issue. Hoping the Network Profile will become available for changing. Using the Network Profile app from Samsung does not work. Says it does not work with my provider. Says active profile is 'Rogers'.
Update:
Probably just lucky, but I have had a steady connection since this morning. I set option 2-7 under Diagnosis option *#2263# (use all WCDMA Band). What maybe did the trick is enabling Roaming, as mentioned by @colinbo. My apn is set to pda.bell.ca.
Update:
Nope, just luck. :-(

[Q] Data problems Help plz

Ok ive been trying like crazy the past week trying to figure out why i get mms but my internet always takes to that web2go upsell site. Im on T-mobile here in the us and it's driving me up the wall and again sorry im not trying to bring up a question that's been asked a million times but I do have unlimited web on my plan and yet I have no web. I've input a number of different apn variations and still mms no internet. is there a kernel I should be using or is my plan just dumb because my phone shows on the status bar that I have 3g and h+ but web2go is the absolout death of me......and i know my data works because I use to use a jailbroken iphone.
Im currently running MDJ's CyanogenMod 7 (v. 2.2) A2SD I honestly can't remember my radio type and plz any help would be much appreciated.

Let's see if I can help.
Are you sure you are on the T-Mobile Data plan and not the grandfathered old T-Mobile Web plan?
Here are my APN Settings:

Everything I didn't mention is left alone.
I flash several times a week. From CM, Gingerbread, AOSP and Sense builds, these settings work 100% of the time for me.
Hope this helps!
Itried the settings you posted and still no go. I'm gonna give T-Mobile a call later on to find out if it is my plan. Thank you though.
Any update on this ? Same Issue started overnight
Having same issue - HD2 with various Android ROMs on old TMob Unlimited data plan working combination that has been fine for more than 6 months - now overnight I am getting Web2Go message re data plan incorrect for phone and their upsell site - and of course no data connectivity (was working at 10:30PM - then at 6:30am not working - between putting phone down and picking it up)
Will try suggested settings but have to wonder are TMob doing some kind of rolling update thats killing what older data plans can do.
Any help/advice appreciated
Tubster90
Update
Tried options from Voltron1551
Didnt work
Read HD2 Android FAQ again
Tried just APN value
Worked.......
Fingers crossed
Data Web2Go update
I too, was having the same issue... and here is what I found from T-Mobile Support:
T-Mobile just recently did a network upgrade & a Data Plan change:
1: pushing 4G to more areas
2: new data plans (no more unlimited plans for NEW customers)
if you were ALREADY on an unlimited data plan... those were supposed to be grandfathered into the new setup... but something got messed up during that transition.
I recommend, if you are still having issues (mine resolved this morning... been down for 2 days) is to contact T-Mobile customer support to report your issue.
Hope that helps you guys
Update:
my APN settings are as follows, by the way:
Name : T-Mobile Data
APN: epc.tmobile.com
MMSC : http://mms.msg.eng.t-mobile.com/mms/wapenc
all other fields are blank.
Bit of clarification too regarding this issue... they said the accounts affected were discounted unlimited data plans.
I've got the business card with my trouble ticket #.... When i get home i will post it, if you need the number for reference with TMO support.

I would check NotionInkHacks forums to find the threads on that.

this may or may not be related to your problem, but did you add in the AT&T APN into your NI and have you tried your SIM card into a phone that can handle data on the AT&T network?
To input the APN info goto settings, Wireless & network settings, Mobile networks, access point names. Click your second to last button and click New APN. If the info for the field isn't provided below, leave it blank.

I can confirm this works. The tablet does everything except receive phone calls.
Adam + AT&T Data only plan for Tablets.
I went to the store asked about this, the rep didn't know how to activate the Tablet Plan on a 3rd party Tablet. He suggested I call Customer Service. I asked him for a SIM to take with me when I call so I could save time and get it working.
I called CS, talked to about 6 reps~, they tried. The main issue was getting past the accepting the terms and conditions via the phone system (IVR), it kept coming back with Unable to process due to technical problems with their system and it would transfer me back to a rep. Reps tried this themselves with me on the line.
BTW, the reps bent over backwards to help. One of the most helpful, I got disconnected while calling another department and working with a supervisor. She called me back a few mins later, says she didn't call me back right away because she wanted to finish her call and have a definitive answer.
She said I would have to return to the store and have them set me up with a dummy tablet to activate the account, then make the appropriate changes in their system.
So today I went to a AT&T retail store once again, but armed with those notes in the account. The rep called, they told him he couldn't do it. So he called another department, had them activate my account using a dummy phone under a voice plan.
Once active he made changes in the account, entered a dummy tablet IMEI then changed to the $25 /2G data plan.
I popped in the SIM, ran through the steps of enabling it on the Adam. 3G icon appeared, tested surfing Google.
I had already added an APN, only editing two things, name AT&T, APN broadband, left everything else default and it worked (this is for data only, voice/data plans require more info edited).

[Q] Atrix 4G in Aus on Trelstra Next G network

Hi All,
Justy recieved my unlocked Atrix 4G, My understanding is that these guys are meant to be next G compatible.
Set it all up, all is working fine, bar the next G network, I can make and recieve calls, access the net through WiFi but no net access through the carrier.
Tried everything, any help.
Thanks in advance
did you try and set the APN?
http://ausdroid.net/apns/
im using my atrix in australia too, but im on the virgin/optus network. i can get my internet data to work.
Thanks abe1990.
I whent through all this with my previous Desire, but for the life of me, cant remember where to access the info i need from.
Just rebooted the device, notsure why i didn't try earlier, all seems to be fine now.
Thanks
Yeh was just about to add - I'm using an Atrix on Telstra no worries. Seems you were just missing the APNs
You can use the Telstra configure page to ensure you get all the APN's correct.
http://configure.telstra.com.au/telstra/index.jsp
It will download the config file to your phone - no need to manually edit.
Hey guys,
little more interesting now. I tried to send an sms, and its telling me that you need to enter a valid number. Im guessing it has something to do with country settings of some soret howver not sure?
Thanks
so i have done the updates successfully, yet still the same message, i have notices when i input the number it appears like a US number, i.e 111-111-1111. not sure if this is the issue.
Thanks for that guys. I have done the auto set up through telstra and all seems to be working. The problem now is that when sending sms i must add +61 in front of all numbers otherwise it doesn't recognise and says invalid number. Is there a setting for this, a can't seem to find anything.
Unusual, im not having a problem. Maybe try downloading MoreLocale 2 off the market, it changes all your regional settings to Australia. Add EN AU to the app. It may help..
Hey, how is your data coverage on the go with telstra, I'm on virgin here and its good if your standing under a tower (five_six mb/s) but on a train line or anywhere else it barely manages to update facebook.
Sent from my MB860 using XDA Premium App
I'll have to give more local a go and keep you posted. As for Data coverage with Telstra, I have now been through all the networks and I find it by far the best. Carparks, lifts, city everywhere really, a little pricer but worth it.
Hey guys I just go my Atrix today, I can't seem to get my phone to connect on the Next G network. If I do it always come up with a error everytime I turn my phone on and off, it always ask me to try and select another carrier. Plus I don't get the Telstra Newtork on the notification bar its just blank. However if I hit cancel it will let me stay on the Next G network but when I call or recieve a call for Next G numbers it crashes my phone and forces it to reboot. Just wanted to know if anyone else is having this problem or is it just me.
The only way I have worked around this is using the 3Telstra network, which kinda sucks cause I need the the Next G coverage.
Any one having issues with the mobile hotspot. At first every time i went to use it would have to change the mobile APN auth type to get it to connect.
Now after upgrading to .57 i keep getting the u need to pay at&t to use this msg. Any thoughts
Im on telstra and have had the phone 3 weeks
Got mine last week from Bell Canada, and after setting the APN's, running so sweetly on Optus HSDPA.
Mine doesn't suffer from the random muffled voice issues the AT&T phones are experiencing. The Bell Canada phone doesn't loose any APN or carrier settings on reboot.
Theoretically with the 850Mhz band support it should work on Telstra NextG, but who knows. Sounds like AT&T are severely locking down their phones. Glad I got mine from Bell (and logo free)
Hey buddy. I'm on Telstra as well. Call them on 125880 and follow the prompts until you speak to someone. They will text you an update with all the settings. I literally just did that 5 minutes ago

cheetah2k, how is your phone working on optus?
Downloads don't work for me when im on 3g, only H and 3. (i'm on tpg)

Where you guys get your unlock phone from? i m interested in getting one for use in SG

No doubt it depends on the area you're in, some areas will support 900Mhz only which the Atrix doesn't have.
On the south side of Brisbane, I've yet to have a situation where it drops out of H+ for data. What APN settings are you using?
dio, i bought my phone unlocked from negrielectronics so they sent me the code.

That didn't work for me so all i did was create one, give it a name and save it. So my APN only has the default settings, i.e MCC: 505, MNC: 02.
I do drop from H quite often in Sydney city, I then have to wait until it finds H again. Maybe there is someway so it doesn't attempt to connect to 3g?
thks... will check out the site. btw is it a at&t branded phone?

[HELP] Got AT&T sim into International S3, calling works but data doesn't work

I got an international S3 from India and went to AT&T store to get a micro sim.
Got that installed and then the phone calling works fine but data (internet) doesn't work.
They said they would have to register my phone's IMEI but it still doesn't work. They put in a new APN, and still same. They called their tech and they couldn't help. Their last suggestion was to try calling Samsung, but I had to leave to get to work.
I believe there are already people using International version with AT&T for the S3. So any ideas what could be wrong?
Thanks!
Try factory resetting your phone. Other than that, make sure you have the $10/month data plan (unlimited messaging required) or the $15/month data (no messaging required). To do that you'll have to call into customer care and say you have an unlocked non-smartphone. If you go into the store to do this they'll give you the more expensive internet because they'll see you have a smartphone. If you're changing data plans it CAN take 24-48 hours for it to be effective, although it usually doesn't take that long. After that's done go into Settings, More Settings (under Wireless and Network settings), Mobile Networks, and then Access Point Names. Make sure there is an Access Point Name titled "Cingular 410". If there isn't then press Menu, and then "+ New APN". The settings should look like this:
Name: Cingular 410
APN: wap.cingular
Proxy: Not set
Port: Not set
User name: [email protected]
My Password field is auto-filled, so I don't have that. Try leaving it blank, but if that doesn't work call customer care and get that information.
Server: cingulargprs.com
MMSC: http://mmsc.cingular.com
MMS proxy: wireless.cingular.com
MMS port: Not set
MCC: 310
MNC: 410
Authentication type: Not set
APN type: default,supl,mms
APN protocol: IPv4
Enable/disable APN: Checked (this field is grayed out for me, but it is checked)
Bearer: Unspecified
This should fix it. The only thing I'm unclear on is the Password part.
Password is (all caps): CINGULAR1

Well now my SIM is completely unregistered, can't even make calls. Operator asked me to go to the store and get a new SIM Card.
So, this won't work without the switch to the non-smartphone data plan? It is going to be hard to pull off when I am in the store.

It should work just fine on the smartphone data plan, and you should be able to switch to the non smartphone data plan afterwards.

Ok, thanks. What should I tell the AT&T store people today when I go in the evening?
It feels like they did something on the account to screw it up. Would it help to suggest that they get this working on an AT&T HTC OneX and then transfer the SIM to my phone?
It could be that you have a defective SIM card. Take it one step at a time. Replace the SIM card. Make sure you have functionality with other services (such as voice and messaging). Check all the APN settings to make sure those are correct. Make sure you have a data plan for AT&T.
I'm on another carrier but I had the same problem at first, only phone call and sms working. I had to change my APN for the Data to work.

What did you change your APN too?
Edit: nvm, you said another carrier

All of the APN settings for AT&T are in my first response. Double check that yours look the same.

I got an international S3 from India and went to AT&T store to get a micro sim.
Got that installed and then the phone calling works fine but data (internet) doesn't work.
They said they would have to register my phone's IMEI but it still doesn't work. They put in a new APN, and still same. They called their tech and they couldn't help. Their last suggestion was to try calling Samsung, but I had to leave to get to work.

What are the APN settings you input, did you save and select it afterwards?
EDIT: Check the settings in the screenshots on the first posts of this thread, yours should match.
Thanks, I went back to the store. We got my original S2 working and this time switched to micro sim without making any IMEI/etc changes and it worked.
Anyone know what extra steps need to be taken to get the voicemail working?
