[Q] I have tmobile, with Data plan, but does not work on my G1

So I've done plenty of searching, enough so that I was able to unlock my phone without the data working, rooted my phone, flashed and modded it, successfully running newest Biffmod.
That being said, i'm 100000% sure I have a working data plan, my plan is unlimited everything.
Works fine in any of my other phones, Dash 3G, HTC HD2, Unlocked Samsung blackjack i607.. The difference, those are all windows mobile phones?
But the HTC HD2 Dual boots android 2.2 froyo and data works there.
Yup, same sim I'm talking about, same plan, just different phones.
Any Idea why my data plan is not working with the G1? Am I doing something wrong? It worked when i FIRST got this phone (ordered it off ebay not that long ago to play with).. After factory reset/wipe before modding is when it all went sour.
Was stuck on log in screen so I had to do the work around to get into the phone, obviously not with Biffmod I can skip.. But I cant use market place, check e-mail, ANYTHING data related. Yet my Icon says 4 bars, 3G and I even see the "up" and "down" data xfer arrows giving me activity.
It's as if it's "there" just not working.
Any help would be great appreciated, I plan to go to T-mobile and hopefully one of the people there will actually have some tech savvy.. Wishful thinking.
Long story short, I just want my data to work. Please, and thank you.

Do a search on here for the correct APN setings for your provider.
edit: here's the thread http://forum.xda-developers.com/showthread.php?t=475564

Read the thread, it's for ATT users trying to use a T-Mobile phone.
The issue is that I actually have T-mobile.

I'm fairly sure I saw the apn settings for t-mo in there too. That's probably what you should be checking first.

Just google Tmobile's US apn settings or grab them from another of your devices, then it will work.

Perfect, I'll give that a shot when I get home from work today, thanks for all the help so far.

Enable Data Roaming Setting Not Retained

Like many others, my phone has a tendency to drop 3g unless I enable Data Roaming. This has been the case with My D1 with 2.3.3.
Now that I have the Droid 3, I have the same thing. No surprise there.
HOWEVER, when I enable Data roaming on my D3 and then go into an area where the phone drops to 1x then no data, I get a notification that Data connectivity has been lost because Data Roaming is Disabled.
If I pull down the notification bar, it says I can select the bar to go to the setting. I do. Sure enough, the Data Roaming Enable box is Unchecked.
I check the box. Go to my home screen, and the notification will reappear. I can do this all day.
If I go to my home screen, ignore the notification and go to settings, battery & data manager, then data delivery, the setting is unchecked....BUT....If I access the menu this way; the setting will be retained until the phone is brought to an area where data signal does the 3g to 1x to no signal thing. Then it starts all over again.
Any suggestions? Anyone else getting this? I received my D3 over a week ago, and finally exchanged the phone for another one. That phone lagged and had random freeze issues. This phone has none of those issues, but still has the Data Roaming Enable setting not retained problem.
Wasn't this an issue with CM7 at one point? The d3 claims to be running 2.3.4, but it is hard to tell with all the Motoskin draped over it.
I have also noticed that (in my area) if I have data roaming enabled, my battery life is much improved. With it off, my battery drops like a rock.
I have contacted Moto about the issue and reported the bug; but all I am getting is the "we'll look into it" brief email. Like I'm some kind of first-time Android user who doesn't know how to use my phone.
Please tell me someone out there is having this too, or that there is a patch that Moto just hasn't released yet....
Thanks in advance everyone.

UPDATE:
2nd phone, all data connection is lost. No phone, 1x or 3g. Phone is awake, and battery settings are set to Performance (No Battery Savings).
Data manager is disabled (no stoppage of data)
When going into an area where I ALWAYS had "EXTENDED NETWORK" data available at 1x speeds prior to this phone, the phone says no data connection.
I look and my Data Roaming Enabled checkbox has been unchecked.
I check the box, click OK to agree that I may incur Roaming charges. The phone will reconnect to data at 1x or 3g depending on where I am.
If I look at the phone 5 minutes later, the checkbox is Unchecked again for allow data roaming. Sometimes less.
This only happens after the phone goes into a weak coverage area.
I have tried rebooting the phone. The setting stays retained after reboot, but is lost as soon as I go into poor coverage.
I have tried factory reset. Setting stays until I reach a poor coverage area.
Already exchanged for another phone. Same issue.
Changed phone from Global to CDMA mode and network to automatic. Setting still does not hold.
It is most strange though, that it doesn't happen until after my home network is lost. The setting will hold until then.
Without that setting checked, I cannot connect to my "Extended Network", which in my area is a no-cost option. I keep checking the box, only I can't get the setting to stick when I go to a weak coverage area.
The coverage area should not make changes to the retention of allowing of data roaming checkbox. Something is improperly referenced in the software.
Motorola's out-of-country sweat-shop customer-no-service department wants me to ship my 2nd brand new phone to them (5-7 days for them to process and receive it+whatever it takes to ship to them) and take between 14-21 days to "repair" the phone, and then take another 5-7 days to package, ship and return to me (all at my expense). Why am I sending a new phone that is defective "out of the box" to be repaired??
So I'm supposed to go without my phone for 5 WEEKS because they have a software problem??? It can be duplicated every time, and on more than one phone. They have the old one. Fix that and send out the update please!!
Am I the only one that has had this issue? Seriously, no one else?
Any help would be greatly appreciated. This is frustrating as heck. I love the phone, but this is ridiculous and makes it rather un-usable depending on where I am. I NEVER had this with my D1! Moto, what happened?
Thanks everyone. +1 if you've had the issue please.

Same Problem
I also have this same problem.
After reading other forums, I thought it may just be the Droid 3 or a Motorola problem. I ended-up turning back in my Droid 3 after Motorola said it was a Verizon problem (which really is not the case). Now, after reading your thread, it makes me wonder if this is a Android OS issue.
I really hope it is not a OS issue, I have wanting an Android phone for a long time.
At my house it always kicks off the data roaming option. I really have no idea what is causing it.
Just wanted to post so that you know your not the only one!

Thank you.
I have run a logcat and have traced the problem to Motorola's battery and data manager service. It is not the OS itself, from what I can see.
It seems that under these particular conditions, the battery and data manager service crashes. Though this should not be a major problem in and of itself, though still not right and needs fixing there too. The service promptly restarts and then loads the settings that were enabled at the time of the crash from a secure data folder. (Or it's supposed to)
The problem comes into play when these settings are loaded. Enable Data Roaming is "loaded" as No(off) any time the service loads these values after a crash of the Battery and Data Manager service.
Unfortunately, as usual, Motorola is dragging their feet at releasing the source code for the Droid 3. This may or may not help the issue, as the Battery and Data Manager service that crashes is a part of Motoblur. Meaning, they aren't going to be forthcoming with the information.
They also are being a typical OEM in their refusal to believe that they could have made a mistake when programming and that they have something to fix.
My Droid 1 has run 2.3.3, 2.3.4, and 2.3.5 and this has NEVER been an issue keeping the setting retained. This is not an issue on our INC2, which is running 2.3.4 in all the same areas that cause my D3 phone to lose the setting. I am also running an Eris with 2.3.5 and it does not have the issue. This is strictly with the D3 from what I have seen.
It's funny how Moto is blaming Verizon for an issue they say doesn't exist. If there isn't a problem, how can that be the network's fault??? The network doesn't change that setting in the phone. Software changes it. In this case, poorly written software added onto the Android OS. Too bad, the OS works fine until Moto putzed with it (Blur).
The OS is not the issue here, it seems the D3 software has two problems:
1 the Battery and Data Manager service shouldn't crash like that.
2 it should return the proper settings if it does.
If I had the chance to do it all over again (knowing what I know now), I would have said send me an INC2 as a replacement. I honestly figured it was a phone hardware problem and the new phone (under warranty) would fix it.
Honestly, I am completely disappointed with this device. That may change when root is obtained and I can get rid of the poorly written trashware that seems to plague this phone. But right now I'm most disgusted with the fact that it doesn't work right and Motorola couldn't care less, even though it's their sofware that is the problem.
I have pruchased my last Motorola product, and am not holding my breath that Motorola will either care or fix their problem. I am certain the future rooted ROMs will be able to transform this lagtastic, glitch-ridden, battery pig into the elegant piece of hardware it has the potential of becoming.
Sorry Moto, sometimes the truth hurts.
Thanks for the support that it isn't only my phone or service area.
Others please +1 as you experience it. The issue is logcat documented and now confirmed on at least 4 devices.

I have this issue as well. Now that we have root, do you have any ideas on how to resolve it?

This is the response I received from Motorola. They need to get a move on with a fix for this huge goof up.
"Thank you for reaching out to Motorola.
We apologize for all the inconvenience and appreciate your patience. The Support Engineers have been made aware of the issue with the "Data Roaming" feature of the phone; and there are currently working on a possible resolution for a future update. You will need to manually change the roaming option back until fix is available. The Support Engineers have not provided an ETA on when this will be available.
If you have any additional questions or concerns please contact Customer Care at (800) 734-5870."

The latest developer update, which is currently in soak testing, has fixed the issue for me.
No formal release date yet on the over the air (ota) version's release date, but I would expect out in the next couple of weeks as long as everyone else had the same results I had with the test update.
Update will upgrade system version from 5.5.959 to 5.6.890, and the baseband radio will be updated at that time as well as the kernel.
So there does seem to be a fix, despite the terrible customer service at Motorola. Honestly, it sucks! I had this update last week, and I'm sure somebody knew this was intended to fix the problem. Not once has Moto asked for information or applied for releasing a phone that was not ready.
Instead, we got canned bot responses and the general feeling that Moto just doesn't care now that they have our money. It is really sad.
Lets hope Google can straighten it out.
Fingers crossed. Though now that we have root, and a custom recovery possibly by week's end; I could care less about Moto. My next phone won't be Motorola...fool me once, shame on you; fool me twice, shame on me.

I have also flashed to 5.6.890, re-rooted and de-bloated. So far, the new radio has done nothing to help my issues with the data roaming becoming disabled. Have you tested the new software under the same conditions as the old?

I may have to retract my last statement... my phone did auto disable the Data Roaming once after updating, but since then it has been fine. Hopefully the update truly did fix it!

I have purposely tried to get the setting to fail. Same result for me as you saw; I got the same old warning once and have not seen it again in over a week now.
For me this was huge, as it failed 20 plus times a day at work. All I had to do was walk down one specific corridor, and by the time I got to the other end my setting would have been unchecked. So going a week with it staying retained (in global mode too by the way) is monumental proof for me it is fixed.
Now I have seen this on the D2 global twice this last week. They don't have a fix yet either, but technically this one isn't official until it's pushed ota.
Good luck all. More news as I have it.

I can't STAND this problem! Happens to me every day at work. Heck, even if I had a widget button that I could turn on the data roaming with from my desktop would be better than having to go into settings everyday
Annoying!

I was thinking about it, but I was hoping to wait until it's officially released. Taking longer than I expected

Still happening in 5.6.890
I'm also suffering this very annoying problem, and have found no solution for it.
I'm using stock XT862 5.6.890 and I need to re-enable data roaming 20 times a day. I use a carrier in Spain that has very little owned towers so it's doing national roaming very often. Every time I switch from an owned tower to a roaming tower, I get the "Data roaming is disabled" notification and need to go to "Battery & data manager" -> "Data delivery" to re-enable it.
I have searched A LOT and tried all solutions I have seen, i.e. modifying build.prop in a myriad of ways, but it still happens.
I have also tried Minimoto v1.7 which has XT862 5.7.906 but it's even worse: It still happens but that ROM has stripped out Battery & data manager so I can't even enable Data roaming. A shame because the ROM is really awesome.
Please help a poor soul! :angel:

I finally took the problem in my own hands and managed to make a small app that re-enables data roaming at the touch of a button.
I needs to be installed as a system app for it to work, but it works! :laugh:

AT&T Survey on HTC Vivid

I got a survey from AT&T about my experience with the Vivid. One question was to be specific about the things I liked the LEAST. Here are my responses. I'm sure I missed a few that you folks have mentioned.
1. Can't remove apps from AT&T and others that I don't want and will not use.
2. Can't remove or turn off Carrier IQ programs that are gathering and reporting data that is not needed for AT&T's "performance analysis."
3. No boot unlocker available yet.
4. Randomly reboots occasionally.
5. Data connection (not WiFi) seems slower than my old 3G HTC phone. I'm not in an LTE area and the radio may not be optimized for non-LTE access (HSPA, HPSA+).
6. The HTC Photo Gallery is a poor app. Had to replace with a third-party app.
7. Notifications are hard to access by dragging down from the bar at the top. It's hit or miss as to whether it will work.
8. Setting to allow Vivid to stay on while on AC is not under Display settings. it's under Applications/Development. That makes no sense.

I saw this last night.
Mine were the lack of an sd card while the thunderbolt came with a 32GB card, ... I unlocked processor, ... I forgot to mention this thing had a lot of trouble establishing WiFi connections.
Most of my complaints had something to do with att's crap and how they mess with devises, everything else seams ok to me...but this is my first android phone...
My signal and data speeds are actually really fast on this phone, without LTE, faster than my home internet half the time in fact

Just sent my response. Covered the big three
1. Can't remove AT&T apps I don't want and don't use
2. Can't remove, opt out, or disable Carrier IQ
3. Boot loader is locked.

same 3 reason I listed.

You guys should probably have listed the locked bootloader as first priority..

Did mine last night.
Listed locked bootloader as only problem / issue.
I also stated that I've had only HTC phones since the Tilt, would not recommend AT&T to anyone & and am thinking about returning this phone because of bootloader.
I paid for Titanium Backup and can't use it (easily).

So.. anyone gonna bother mentioning how they are getting these surveys?

As the end user i.e. customer? via email. (hope that is what you were looking for in your question)

I got mine yesterday via email and replied to it ironically also complaining about bootloader (lack thereof) and carrier IQ.

Basically gave them a fairly decent response tempered by raising bloody hell about CIQ. I could LIVE with a locked bootloader, though I don't like it at all. CIQ I cannot and will not live with though.

I actually get better 3G at home than I did with my Blackberry Torch. Average 3 mb/s, just outside of DC and Baltimore LTE.

I own a skyrocket and got the survey i put locked bootloader as a reason i did not buy the vivid. Lol trying to help u guys out. I went through the bootloader bs with the evo 3d

Note 3 LTE problem

Hey,
So I've noticed an issue with my LTE connection, and I couldn't find a similar issue on XDA:
Sometimes, I'll randomly drop from LTE to 4G, and cannot get LTE back unless I cycle through airplane mode or restart my phone.
This happens on more than one occasion:
1. I'll go into CALL SETTINGS, and when my phone checks the network, I lose LTE and stay on 4G.
2. I'm coming out of an elevator, and I'll drop from LTE to 4G.
I've tried reaching out to Samsung and AT&T, but both blame the other (go figure). Since my phone is still under manufacturer warranty, Samsung said they'll repair it. However, I've heard some bad reviews from you and elsewhere about manufacturer's repairs, and I'm not so sure if that's the best solution to ship my phone out to them.
This phone isn't rooted or unlocked - nor has it ever been.
I'd love to hear your thoughts. Has this happened to you? Do you know of this issue? Any possible solutions other than shipping to Samsung?

Sorry you're having an issue with lte. I don't know of a fix for ya. But I have some last ditch efforts to go thru before you send it away.
1. Open settings -more networks -mobile networks -access point names. Make sure "ATT Phone" is enabled, and verify it's apn settings with your carrier.
2. Find another person on same network as you and compare if lte drops at same time.
3. Request a new sim card from carrier. They are free and only takes a few minutes to swap. You can walk into the store, or request one online.
4. Perform a factory data reset. See if anything improves. You'll need to do this anyway before you send it off. Don't forget to back it up first! Use kies, or your favorite app.

Hey,
I verified my APN settings, tried a new SIM card, and even factory-reset my Note 3. None of those worked. However...
I ended up taking the device to an AT&T Device Support Center, and got it replaced in 15 minutes! The tech there agreed with me that there was nothing else they could do except replace the device. Since my Note 3 was still under the original manufacturer's warranty, AT&T replaced it in minutes - no questions asked.
Now my phone is running perfectly. No dropped LTE!

Glad to hear you got a replacement! Thanks for reporting back.

Weird issue with no data while making phone calls

Hell of a story, I apologize in advance for the length, but maybe it'll be intriguing to some of you. Pure Nexus rom as of i think april 23rd?
I have a Nexus 6 that I bought 2 years ago in April on Verizon (purchased from verizon). My contract ran out April 27th, went to AT&T with my girlfriend because I was going to get on her plan to save money on our phone bills. Ported over the number to my N6 fine. But I noticed I only got an H+ symbol, no LTE. I asked the guy if that was normal, he said yes. I got data and could make calls so I figured it was fine. Did some speed tests, 2 mb/down at best. My GF was getting 15-20 in the same spot on her Galaxy S7.
Long part of this story short, the tech they put me on the phone with said it was due to it being a Verizon variant and was not capable of full LTE speeds on AT&T. I went to the Verizon store and asked if they could put me back under Verizon after explaining the problem. He said sure, and then worked up pricing to have my GF switch to Verizon with me instead, and to get a Pixel XL.
So far so good, they had to do a temporary number for me because there's issues porting a number twice in a 24 hour span, but they cleared it up, got my real number ported, happy camper, good speeds. Except this one issue.
Now when I'm on the phone (actual phone call), my data drops. The LTE signal actually disappears, and nothing displays except signal bars. As soon as the phone call is over, it comes back. I never had the problem before this whole back and forth mess. I can't seem to figure out any options to make it not do this. I was thinking about reflashing my rom in case that would help, maybe something got messed up in the switch back and forth to GSM and then back to CDMA?

I'm already unlocked, rooted, TWRP'd and using the PureNexus that came out end of april (I haven't flashed the one in may yet). I believe I'm also currently using the latest radio and latest bootloader.
Edit - I actually was not on the most recent radio, but I did flash that, no change.

The volte provisioned flag turned on in the testing menu? I have a setting for enhanced 4g lte mode in my settings, wireless networks/more/cellular networks settings. Did they remove the advanced calling from your account? Just throwing some things out there.

The tech may not be wrong as Verizon uses band 13 as their main LTE band and ATT uses band 17

Now when I'm on the phone (actual phone call), my data drops. The LTE signal actually disappears, and nothing displays except signal bars. As soon as the phone call is over, it comes back. I never had the problem before this whole back and forth mess. I can't seem to figure out any options to make it not do this. I was thinking about reflashing my rom in case that would help, maybe something got messed up in the switch back and forth to GSM and then back to CDMA?

In others countries we don't get the same bands management, then I can't say anything about LTE.
But I'm on PureNexus 7.1.1 and I get the same "issue" about network droppin when calling. When the call starts, my phone turns into don't disturb-mode and recover the network only when the phone call ends.. It doesn't really cut my network connection, but it looks like. It may be rom settings.
However I don't care as long as everything works good, it's just an icon. (how a phone call can be done while network is shutted off ^^)
When I was on the stock ROM, this autumn, 7.1 version of Android did the same thing, loosing data connection while being still connected to the network (but at anytime not just phonecalls). Finding it back some minutes later. That was fixed with 7.1.1. Stock.
Hope that might help you (looks not ) if it's the same problem. May be give an eye to the Rom settings..
Have you tried if your device do the same thing with an another Rom ? (stock for example)

The volte provisioned flag turned on in the testing menu? I have a setting for enhanced 4g lte mode in my settings, wireless networks/more/cellular networks settings. Did they remove the advanced calling from your account? Just throwing some things out there.

I knew something looked like it was missing. I don't have any enhanced 4g LTE settings in that section. Normally there's a tick box to turn it on there. It's missing. Is that due to them not having it turned on in my account?
Also for everyone else, this problem only started when I tried the whole at&t switch. I was on this rom when I switched and it worked fine before then. I didn't factory reset since then though, wondering if I need to try that.

The tech may not be wrong as Verizon uses band 13 as their main LTE band and ATT uses band 17

The tech is definitely wrong; since it's a Nexus 6 (presumably XT1103) it has all the possible LTE bands used in the US. There should not have been any issue when switching. I had something similar happen to me, when I just switched to verizon and did the "reset network settings" button, it screwed up my phone so I couldn't use LTE period, I had to reflash the modem in order to fix it. I know you already said you reflashed the modem, but I'm not sure what to suggest. There is absolutely nothing physically wrong or incapable about your phone, just some config got screwed up somewhere along the way. I'd just try to flash as many things as you're comfortable with without losing your userdata. Like modem, bootloader, etc. until your data comes back. If nothing else, press the network settings reset button and flash the latest modem. Make sure your twrp is up to date as well.

I think i'm going to reflash my rom today. I did the modem, twrp is up to date, bootloader is fine. I did the reset network settings (I was sure that was going to fix it, no dice). So I'm going to reflash the rom today and see if that fixes it. After that I have no idea what is left to try other than reverting to stock, which I'd like to avoid.

Yes, it is a feature that needs to be added to your account. Go online and check their website or go into the hidden menu and activate it. If it sticks, it's on your account.
I tried the wifi and video calling flags and they didn't stick. Go figure... C'MON big red...

How do you enter the hidden menu on the n6? I thought I found it but it wasn't working.

.#.#4636#.#. select the phone info tab. In there, there will be either a drop down menu or buttons to tick and they'll change color

I got in, VoLTE was not ticked. I ticked it. I got the setting for it then in settings. But making a phone call gave me an error. I rebooted, and it's not ticked now. So does that mean I need to call Verizon to have them flag my account?

You need to add it in your account then. Easy enough to do online. You want to, "manage features."

That did the trick. All fixed. Thank you! That was driving me nuts. I never considered the idea that the setting would be turned off . But since I did leave and come back...
Thanks again!

Glad you're all set. ?
