[Q] Installed CM 7, 3g will not lock, edge works fine - Nexus One Q&A, Help & Troubleshooting

Just flashed to CM 7 and everything work great except mobile data.
It is able to get edge data, but when set to allow 3g data, the phone keeps switching between 3g and H, and never locks on a connection (the icons stay grey).
Any suggestions?
Thanks in advance!

Check your APN settings.

It is currently set to epc.tmobile.com
I tired internet2.voicestream.com before by editing the existing APN and swapping out the APN line, however, that had no effect.
Is that the correct process? or even the correct address?

So, I left the APN the same, turned off wifi, and let it try to connect to 3g the rest of the night.
After an unknown amount if time, but less than 5 hours, I was once again connected.
I guess the phone needed longer to reestablish the 3g connection.

Turn off GPRS without disbling HSDPA?

Is there a way to disable GPRS data WITHOUT disabling HSDPA?
(I see the reverse is possible - you can disable HSDPA from [Settings > Connections] and still do GPRS.)
I have three X series and do not want to get roaming data fees. For those uinfamiliar with threes plans, the HSDPA is very cheap but when you frequently and un noticed roam off their network onto GPRS you slugged with large roaming fees.
Ideally I need plain GPRS data always blocked unless I over ride it and at the same time HSDPA always enabled.
Anyone seen a way to do this. I am aware of Modaco "No Data" but it does not fit the bill for what I want.
Yes, indeed there is. Your post prompted me to figure it out. while I don't get hit with roaming or charges for jumping on edge or GPRS, I do really like the 3G service I have and my house is covered. Usually though it's when I'm driving and listening to internet radio or something, It'll jump onto GPRS/EDGE and the buffer will underrun, not great.
So... your question caused me to figure it out.
It's actually in the phone menu however, if you don't have it setup you have to enable this particular tab.
Real Simple Method:
Start -> Settings -> Personal -> Phone
Click the band tab, set network type to WCDMA and leave GSM/UMTS to Auto(don't change this otherwise you'll cripple your phone's ability to tower hop.)
IF you don't have this tab here's how you enable it in the registry.
Either manually edit your registry and navigate to HKLM\Software\OEM\PhoneSetting and change ShowUMTSBandPage to "1"
Or just import my included registry file to enable that tab. Soft-reset for fun and voila. I've done this tweak now and now my phone stays on 3g even when the GPRS signal is far better. I'm quite happy with this setup.
Enjoy
On a stock Tilt, even if that reg key is set to 1, it still does not show the Band tab.
Vexamus. No this it not a solution for me as it changes both Voice AND Data. Making the switch you recommend, kills my voice capability as I am currently roaming. I need to be able to make calls when roaming outside of my home WCDMA network. It is only Data that I want to restrict.
Furthermore having done this, when I set the phone network back to Auto to restore voice, I could not get any sort of connection to re establish. Data or Voice - nada. Even after powering the phone and device on and off!
To fix this I went to the lower GSM/UMTS band box and as I know I am roaming right now, set it to away from Auto to the first GSM option. This allowed the connection to re establish then I set it back to Auto and all is OK again.
So if anyone else sets their network type away from Auto while roaming you may need to toggle your GSM/UMTS band settings to get things back. Once back you can set both to Auto.

I am interested in this too

Sorry that didn't work out for you, mate.
I don't have that roaming problem, I have UMTS coverage everywhere I go so no biggie. And I've been flipping the setting back and forth all day and never had any issue with not being able to reconnect. I'll keep researching it.

I don't think that setting the band is possible with an AT&T rom; moreover, I think it also has to do with the radio version.

[Q] Help w/ AT&T Nexus One: four bars and no data!

Hi, I'm having a chronic, inconsistent, and confusing problem. At certain times -- often for 20 minuets or more at a shot -- I will have extraordinarily slow or no data capability on my AT&T Nexus One despite having four full bars: even simple webpages (Google searches, Wikipedia pages, etc...) will take minutes to load or will not load at all, generating error messages. The behavior is inconsistent: sometimes my internet will be fine, and sometimes it will be useless, and I can't figure out why.
I've tried hard-resetting my phone but have quickly run into the same problem. It must be either a physical issue with my device or a problem with some specific app I've got installed. Any ideas?
Thanks!
Alan
What does the data icon show when there's "no data"?
Does it show "G"?
In that case, it's not surprising. Bars aren't a good representation of your data capability - because they don't tell you what type of network you're on. You can have great GPRS reception, and the data rate will be awful (12kbps at best).
If the data icon shows "3G" or "H" - then it might be something with your phone's apps.
Thanks for the response -- I'm 98% sure that it still says 3G when the data stops work. I wanted to check this for sure before responding, but the data dropout hasn't happened since you wrote: I've had background data turned off for the last 24 hours in a shot-in-the-dark attempt to get to the bottom of this, and data's been fine ever since; so perhaps this all has something to do with something that's getting out of control when pulling down background data?
Alan
Well, it's happened again. I'm attaching a picture, for what it's worth, showing the Nexus One unable to get any data despite having four bars of 3G. Any ideas? The problem is intermittent and unpredictable.
Any ideas on how to get to the bottom of this? Do I need to wipe the phone and load apps one by one? Is there any chance that this could be a hardware issue?
Thanks, Alan
Wiping the phone and trying a very minimal set of apps would probably be the best shot.

Four bars of 3g? That's measuring phone signal strength not data speeds.
Sent from my Google Phone
Right -- I understand that the four bars indicate signal strength, but what circumstances would lead to my getting _no_ data despite having four bars of 3G? We're not talking slow data, we're talking about _nothing_ coming through, leading to web pages timing out, sync generating "data connectivity problem" errors, etc... I don't think this is a normal occurrence, even with AT&T.
He just told you. Your bar signal has nothing at all to do with data. You do not have 4 bars of 3g. You just have 4 bars of cell signal. The two do not have anything to do with each other.
Sounds like you do have some kind of problem though. When you are in a area with no data or 2g the data icon should change accordingly.
Stop looking and thinking that your bars have anything to do with data speeds though.

Wrong -- you don't understand that the four bars indicate PHONE signal strength, you know, like can you hear me now? find out your providers apn and enter it manually. does the browser work? Does wifi work?

I'm on AT&T, and the APN settings look OK. They are:

APN: wap.cingular

What changes should I try making which might solve this problem of intermittently getting no data access? (The browser works fine when data is flowing properly. But there are these occasional periods -- lasting minutes at a time -- when I get no data. When that happens, of course, the browser times out and generates error messages. I haven't been able to figure out conclusively if WIFI works during those periods.)
Thanks, Alan
[I should add that this didn't used to be an issue with my Nexus One. Something has changed in the past month or so -- either on my phone or in AT&T's network -- to make this suddenly a chronic problem.]
Did you already try using *#*#4636#*#* in the dialer and selecting "WCDMA only" in the "Phone information" area?
Also, obviously, make sure you have a data connection, not just bars (if you have four bars and no "3G", "H", etc, then you have no data connection - reset your radio!)
Did you pay your bill on time?
Sent from my CM7 G2
Thanks, everyone! Yes, I've paid the bill on time, and it always says 3G in the notifications bar on top. This is an intermittent and chronic but not a constant problem -- there's generally one or two five-ten minute periods every day where I'll have no data.
I'm trying the "WCDMA only" setting now; I'll report back if it makes a difference.
Thanks, Alan
Hmmm .... Well, I've had another data blackout event (lasted about 7 minutes) since changing the phone to "WCMDA only." During the blackout, I couldn't pull any data down over Wifi either. Now everything is fine again. Does anyone have any idea what would cause periods of no data access over 3G _and_ Wifi?
Thanks!

when this happens what are the arrows next to 3G doing?
On a side note... What configuration has been thought as a battery saver?
Sent from my Google Phone
What ROM are you using? Are you on stock or using a custom ROM? Also, did you try wiping cache and dalvik already? This sometimes fixes weird bugs for me.
Are you roaming when this happens? On my AT&T band N1, sporadically throughout the day it will be "roaming" on AT&T's network even though I have AT&T as my provider. To fix I just manually select AT&T on the network selection screen. It might help you?
Btw, have any of you heard of the problem I'm having?
EDIT: I just realized that on my APN settings the password for wap.cingular wasn't entered. This might fix it I suppose; We'll see.
Also, instead of setting WCDMA only, shouldn't he set it to the one that prefers the EDGE network over 3G if it is the 3G network that isn't responding? Maybe he just has iffy 3G in his area.

AT&T Tab will no longer connect to AT&T data

I bought an AT&T Galaxy Tab. I confirmed when I received it, data worked, and then discontinued my service.
In the meantime I flashed to Overcome ROM, flashed to JPD to enable phone calls, brought it to Canada and used it there with a Canadian GSM provider, and now am trying to reconnect my AT&T service.
I activated my AT&T service about an hour ago, and everything seemed to be fine. I received the welcome to AT&T text message. However, it just won't connect to any data of any sort.
I've reflashed the modem to JPA, which I've seen people say works on AT&T, without any change.
I've installed the AT&T data usage widget, and it says "No Network Available or SIM could not be verified".
My APN settings by default were set with everything normal except for an empty password compared to what I found online. I tried setting a password and no effect.
Under Settings => About device => Status it shows Mobile network state as either Disconnected or Connecting.
Settings => Wireless and network => Mobile networks => Use packet data is unchecked, and whenever I try and change it, it will change to "Turning on..." and then after a few seconds it will change back to unchecked.
All of the Samsung related data connection toggles like on the pull-down windowshade or on the long press of power act like they're changing something instantly, but have no effect.
Anyone have any ideas on what's gone wrong here?
Someone stated earlier that their tab was kicked off of the network as well. I would try a series of restarts to see if the problem persists. If it does, try contacting at&t directly.
I Haz 3D!

I've restarted it about a million times in the past hour. I'll give contacting AT&T a try, hopefully it won't come up that I'm missing something from the stock ROM.
Called AT&T, they knew absolutely nothing, and couldn't help at all.
I suppose I'll try flashing a few more modems, including stock, and then I suppose I might have to reflash to completely stock if that doesn't fix it.
Try the sim card in another phone. They might not have apportioned it correctly.
Any modem will get you at least voice and EDGE, so don't worry about that now.
I have wap.cingular apn for a voice and data plan.

Hmm I'll see if I can dig something up. However, I'm a little unclear on what will happen because this is the $15 AT&T Tablet data plan, and at best I might be able to scrounge up a phone.
The sim card automatically entered wap.cingular apn on my tablet plan as well.
I was soo excited when I found this thread. This is clearly my situation exactly:
http://forum.xda-developers.com/archive/index.php/t-1083173.html
I was using the voice APN on a data plan. I deleted all the old APNs, created a new one that is just Broadband/Broadband for name/APN. Rebooted.
Hit connect, and.....it's still screwed up. Now it flickers back and forth on the status page between Connecting and Connected, and the status bar up top reflects the same - I'll see the H with arrows for a half second, and then it'll disappear again.
On the Mobile networks page, Use packet data now similarly flickers between checked on its own and unchecked and gray.
Okay, no idea why, but everything works now.
After Broadband failed to work, I tried changing it to APN Broadband. That didn't work either, so I changed it back to Broadband. Things then started semi-working in that the connection was still flickering on and off, but when it was on, data was actually being transferred.
I rebooted, and now it's fully working. Hope it stays that way. Seems to shift back and forth between H and 3G a lot considering I'm in the middle of a city with full bars not moving, but other than that, all seems well.
It would have been good to know about 1,000 word ago you only have the $15 broadband sim!
Apn is: ATT BROADBAND, and nothing else.

Hmm I have it set as Broadband, not ATT BROADBAND, and it's working for now so I ain't touch it.
Are people able to activate an AT&T Galaxy Tab on anything but the broadband sims?
Yes, I have voice and 3g data by ising a sim from my old android phone.

Dropped data roaming on digicell in Turks and Caicos

My n6 connects to digicell and I have data for about 5 minutes then it drops and I get the exclamation point. I can get data every time i reboot. Called tmo and they couldn't help. Tried changing the roaming settings through the dialpad but that didnt work. Im suppoed to have data coverage . Any suggestions?
Found my answer by mistake. Disabled voice over lte setting and set data preference to 3g instead of lte and now data works.

S6 Active on T-Mobile roaming data not working

Wondering if anyone can help me out. I've already spent hours on the phone with tmobile and they can't seem to solve it.
I've had this problem ongoing since getting this phone. Basically I get no data roaming. Places Ive tried: Canada (several cities in BC as well as Quebec and Ontario), UAE, Bahamas. I spend a lot of time in Canada so its a real issue. Things I have tried:
- Factory reset
- Upgrade to 5.1.1 using Odin.
- Try sim card in friend's phone (4G works no problem in Canada)
- A bunch of other stuff I don't remember
Symptoms:
- About 50% of the time the phone works for calls and text
- The rest of the time it says "emergancy calls only". Restarting the phone immediately restores ability to make calls/send text. This happens regardless of signal strength.
- Data connection never works. Only time I got 4G was the very first time I entered canada with this phone. . Restarting the phone would make it connect to 4G for about 1-2 minutes before it would lose data connection. Restarting the phone would bring it back. After about half a day the phone completely lost ability to make data connection and has never been able to get data connection internationally since then.
- Sometimes I get this message: "you have lost data connectivity because you left your home network with data roaming turned off". Data roaming is definitely turned on. I've enabled in settings and also via #RON# short code.

This sounds like a config issue to me. the random drops to emergency seems to be issues with roaming not being set up right. It sounds like your APNs are not setup correctly or something. have you gotten any info from t-mobile on Roaming APNs? i'm not sure if it needs to be adjusted for roaming or not.

Yeh thats what it seemed like to me as well but I went over the APN settings with them on several occasions. I also looked them up online. Everything seems correct. The only thing they had me change was APN roaming protocol from IPv6 to IPv4/IPv6.
Dial *#*#4636#*#* (on stock dialer), in Device Information try to change network settings to LTE/WCDMA.
What are your APN settings? Provide info about all fields.
Did u ever solve this issue ? I'm having the same problem...
