Hey guys I am not sure what's going on but I have the galaxy s2 on at&t and when I flash some roms the mobile data simply wont work i have tried reflashing , enabling and disabling data and it just wont work.
Works on Villain Rom but might not work on other rom.. someone suggested to flash basebands i tried basebands like KI3 , KI4 , KH5 i belevie on this one specific rom and other one and it won't work.
if someone has an answer please help and thank you
I am having the same issue with my SGSII on AT&T on GoPhone unlimited plan. I called At&T today and they said I am using a Smartphone on a none smart phone data plan. I guess maybe Samsung has released the IMEI numbers for the international models to AT&T. I could be wrong so don't think this is written in stone. I did however get internet service off and on flashing other ROms.

Hello everybody, recently AT&T released a new pay as you go plan which is 50$ a month for unlimited everything. Unfortunately the unlimited data does not work on smartphones which is disappointing.
I recently switched to this plan because 50$ a month for unlimited everything is a great deal, what I was wondering was if someone could find a way to allow data to work on this plan\phone.
When you try to use firefox or similar browser it just says the page cannot be displayed, on the facebook android app it gives you a message that tells you data was refused.
I would gladly donate 20$ to anyone who could figure this out, and give me the fix. it seems like something a developer would know how to fix so if anyone has any ideas shoot them at me. If one of them works they will get a nice 20$ donation Thanks.
It sounds like AT&T itself is blocking the data connection.

Exactly, but it doesn't block the connection if my pay as you go sim card is in a non-smart phone. There must be something that tells at&t you have a smartphone, and maybe there's a way to stop that.
What a rip off, i pay 15 bucks a month for unlimited.data

Cell service providers such as AT&T have the ability to know what phone you are using through your sim card.
so it'll be hard to find a way around it, but it's not impossible.
Sent from my x10 Platinum
It's because it's an x10a from at&t if so it's the IMEI that gave it away they have a log of all there numbers if you call an be real nice they will give you the unlock code for free (I did it and it was free any one can on at&t) Then flash a Stock rom and then wait a month or so an cancel that sim and go to another store or have your friend start up another sim. A wahoo
So Patricks_book you're saying all I have to do is unlock my phone and data will work on my smartphone even though the 50$ unlimited everything plan doesn't allow smartphones to have unlimited data?
I don't think unlocking the phone changes your phone's IMEI number, if that's what you are wondering.
I used to have a Nokia E72 that covered AT&T's 3G frequency bands but never sold by AT&T. I don't use that any more but when I did, it worked with their $15 unlimited data plan (for a post-paid plan) that can only be used for dumb phones. It seemed then that AT&T didn't recognize the E72's IMEI # as a smartphone.
I don't know if this works on GoPhone plans now.....

NO But it's worth a try. Unlock it an update to like Wolfs 2.3.3 x10i and if nothing else you'll have a unlocked bad ares phone

when you sign up though you sign up using a sim, not an imei. so your account is only linked to your sim card.
I have switched phones three times and all I did was pop my sim into a different phone.
I think though that it recognizes you are using 3g or hspa data and that is why it blocks it. Aren't those plans for gsm only?
Its about what APN you connect via. Have a look @ this. Settings > Wireless and networks > Mobile Networks > AT&T and you'll need to configure the apn ... I have no idea which one ... But well , thats all I can help .

Yeah you're right your account is linked only to your SIM card otherwise you won't be able to swap phones. But at least on AT&T they seem to be able to recognize if a smartphone (sold by AT&T) is being used.
A few years ago when AT&T only had a $30 unlimited data plan for smartphones or $15 ulmimited for dumbphones, they started forcing subscribers who use the $15 plan for smartphones switch to correct data plans. Many AT&Ters discussed this issue then and the only conclusion drawn based on their experience was that it was through their IMEI #.

hmmm but if you never gave them your imei they would have no way of knowing...
I would say it has to do with either your apn, the bands you're using (and the fact that you're using 3g/hspa), or just they can recognize the pure volume of data you are using.
They have ALL the IMEIs for the phone from the manufactures and from the ones that are or where on their network and when you use your phone it comes up in their system like if you call in to support and they ask for it there just checking to see if it's the right one. So you can try an app like Privacy Blocker to change your IMEI I do not know if it will work but it is an option in the app ( not on the phone just on out going signals for apps ?) An if it does work PLEASE post it in the forum.
Good luck to us all if it does .

That's not correct at all....
the imei does not pop up, I worked for a phone company before.
Unless you sign up with a phone and have given it to them, they do not have your imei...
If the phone was first purchased from AT&T then they have the IMEI. Or just like when an app has access to your account it can read your IMEI your sim card can read your IMEIs it's connected too your phone number contract/pay as you go. Anyone of them even Wally world (Walmart) who ever you get a sim card from can read your sim card/IMEI.

Its a bullsh!t plan. I got this plan, got data to work just fine, but had alot of trouble with it. ie- Market apps, took FOREVER to download.. That was the first downfall. Yesterday morning, I noticed my phone was in Edge mode. I proceeded to reset it, change the Network options in the debug menu, and play with the APN. This morning.. Still Edge. My conclusion? They obviously shut off my 3G. Now, The problem I have with this, is that I havnt used over 100 mb of data yet, and it hasnt even been a week since I got this service. Stay away from this plan.. GARBAGE. Now, as much as I loathe paying an EXTRA 20 bucks a month, Im taking the dive and goin with TMobile. I need my 3g....
I just kind of skimmed over this post (new here) and this alone made me sign up cause I just order X10 recently.
I have this question though; if is not IMEI# that at&t block you with, then is it possible a reflashing could fix it? I have heard of people use different firmware versions; like my old phone, Ericsson K850i there was just plain K850 version (no 'i') that could get 3G I think.
But assume I install new Sony 2.3.3 Android on my X10, would be the key to get around at&t unnoticed ja?
I too have unlimite 50usd plan and tried to use on HTC Aria that was brand with at&t junk. That did not work But I have not try to root it (updated to 2.2 already ) so I not know if reflash would have fix it or not.
Hi guys, I am about to receive a "new" refurb AT&T GSII to use on my T-mobile account. I have not yet received it, so forgive me if this is a stupid question, I just want to be ready for when I get it.
Will I be able to root the phone straight out of the box? I know I need to run the unlocker from the market, but need to root first. Is the phone "locked" like iPhones are out of the box? Thanks!
And also, can I ask what the number 1 recommended ROM is for this phone? I read CM7 has some issues, but are there any CM7 based ROMs that everyone loves?
No, I believe the phone works just fine without a simcard. You should be able to start up odin, flash CWM, and flash a rooted rom all without an active sim card. You can also setup the phone by connecting it to a WiFi network. Once unlocked it will work with your T-Mobile sim.
I don't think the att sgs2 has the radio to work on t-mobile's 3g bands. You'll be limited to edge speeds. If you are ok with that, you should be all set.

Yea, I have no data plan so I'm all good with the incompatible radio. Plus the screen/phone size on the I777 is perfect for me, while the Tmobile one is slightly too big.
I guess I will just follow the guides to root it. Now to pick the best kernel and ROM...
Hi Everyone,
Anyone using the S5830L variant with UMTS 850 & 1900 on AT&T?
Does AT&T's system recognize the phone and automatically add a smartphone data plan? I'm thinking about getting one for a family member who doesn't need a data plan.
So nobody uses this phone on AT&T's network in the USA? Anyone? Anyone?
Ive not seen any AT&T ppl on here.
If the phone is contract then the contract will stipulate it and their site says they are compulsary. If its PAYG then it cant charge you if you havent any credit and you can easily turn data off. Otherwise I expect they will just charge standard daily fees.
I went ahead and purchased one off Amazon.
Instead of the S5830L model I received the S5830M model which has UMTS 850/1900 support.
Works great on AT&T's 3G network after entering the correct APN even though they don't recognize what model phone it is.

Thanks. The phone is for a non-techie relative. It'll remain stock.
I can't seem to find the stock ROM for it anywhere (WHLA1) so I might try my hand at extracting it and creating an Odin flashable stock ROM.

Hi,
I am using CM 10.1 M3. I haven't updated my modem in a long time. It is I717UCLF6. Is that the right one? How do I know which one to use?

It's kinda hard to answer which modem you need without some more details. It's also a personal preference based on where you live. Some modems/radios work better in certain areas than others. What network are you on, AT&T? I'm on AT&T and heard the latest modem for our i717 is the i717UCMB4. You can flash that one in recovery. I used it and it works but for some reason the i717UCLD3 modem is working better for me. I got that modem when I used odin to install this rom, then flashing my favorite rom on top of it. Some people say the UCLF6 modem works better for them. You can get that one here and flash thru your recovery. Sorry I can't find the i717UCLD3 flashable zip. Maybe someone else has a link so you can flash between all 3 and see what works out best for ya.
No need to do any modem flashing. LF6 is the latest and greatest modem available.
Updating.....AT&T released 4.1.2 and a new baseband/modem which can be found here http://forum.xda-developers.com/showthread.php?t=2261713 and is flashable from custom recovery.
I'm testing out a possible switch to T-Mobile. Had AT&T unlock my phone today and got a prepaid T-Mobile SIM in it. I'm getting H+ (LTE?) speeds while doing data transfer and then it drops back to 3G when data isn't being used heavily. I'm on UCLF6. Although I've had this phone for a year, installed tons of ROMs, compiled my own kernel, etc. I'm a noob when it comes to modems and have just used whatever worked. What's the advantage of using a "T-Mobile" modem if UCLF6 seems to be working on T-Mobile anyways? Do you get more speed out of it?
I don't want to lose AT&T compatibility yet as I just got the prepaid T-Mo to test out (been getting crappy reception with AT&T at work and tired of the expensive plan of minutes I don't use). If T-Mo improves my speeds at work I'll probably just pay to cancel my AT&T contract and transfer my number, but for now I'm just testing.
Well I am not sure about the baseband/modem issues on T-Mobile but most important would be the GSM Bands/LTE are compatible. As some AT&T phones don't support 3G/LTE frequencys T-Mobile use. If you are using a prepaid SIM it may not even support LTE for example Straight Talk on AT&T supposedly will only use HSPA+ .
My friend purchased a G900T that was broken for parts, which needed a new screen. Upon replacing the screen, the phone was functional, but he discovered that the IMEI number had been blacklisted on T-Mobile's network. We unlocked the phone to use it on ATT, and the device works fine on the ATT network, with the exception of mobile data. No matter what steps we have taken, putting in custom APN settings, we have not been able to get data to function.
Does anybody have any suggestions as to what might be causing these issues?
Thanks a lot in advance! :good:
Have you tried to flash an AT&T ROM & AT&T Modem?
Or are you still running T-Mobile ROM & Modem?
Still running the stock Tmobile rom and modem. I thought about switching to ATT rom and modem, but I wasn't sure if that would brick the phone or if it should just work with the stock Tmobile modem. Can I just flash an ATT rom?
Just make a Nandroid beforehand.
T-Mobile S5 comes w an unlocked boot loader so you shouldn't have any problem. You put in an AT&T SIM card right?
You do not want to flash AT&T firmware on a Tmobile phone unless you are looking to brick it. You can however flash ROM's from Unified S5 threads (900F, 900T etc.) that are open to multiple model phones.
So if I flashed one of the unified roms, would that change the modem at all? I was thinking that it wouldn't be part of the package. Would just flashing an att modem be a terrible idea? I am using an Att sim card. Thanks for the ideas so far!
No, do not flash an att modem or ROM on a tmo device. It won't work, and it is not meant to work.
Does your subscription have an active smartphone data plan?
Are you getting any data connection (E, 3G, or 4G)_and you're not able to jump on the LTE or just no data at all?
If the answers to above questions are yes, there are a few more things att checks for before authenticating data use on a device.
These fields need to look exactly like this:
ro.product.model=SAMSUNG-SM-G900A
ro.product.name=klteuc
ro.product.device=klteatt
ro.build.product=klteatt
This information lives in the build.prop file of your android OS and you're gonna have to look up how to back up and edit this file. Start off here http://forum.xda-developers.com/showthread.php?t=1948558 and keep on reading. I kbow this is exciting and you want to make it work quickly but it is not so simple. So reading and researching are your best friends.
Best of luck,

Okay, thanks for the info! We are just plain not getting any data at all, and the user does have an active data plan with ATT. MMS messages are not even able to be sent or received. So in this instance, do you think modifying the build.prop to match the example you gave me would resolve the issue? I'm pretty comfortable working with the build.prop on the device and just working the the Android OS in general so that should not be a problem.
So I guess checking the APN settings won't be a bad idea:

Okay, I had checked APN settings before, but I'm not sure if they were specific to the S5 on ATT or just some generic ATT one I found. That thread looks pretty helpful, I'll see if I can give it a shot later today.
You may also consider loading an international ROM for example http://forum.xda-developers.com/showthread.php?t=2732110

I know it's a foolish question, but you never know. Are you sure your mobile data is not turned off? My wife did that a while back.
I'm running a AT&T rom on my t-mobile s5 with out any problems as a matter of fact I have better signal.i just flashed rom not modem
Well thank you to everybody for insight into this. The link that Commodore 64 posted pertaining to the APN settings ended up fixing these issues. I had input different ATT APN settings I found in a different thread previously, but I guess they must not have been right. Still running the stock Tmobile rom and we are now able to get data and 4G with really good speeds.
Cheers!
