[Q] T-Mobile 3G Network Location - Nexus One Q&A, Help & Troubleshooting

Anyone else on T-Mobile having issues with network-based location? I can switch to edge and the phone can use the cell network to determine its location but when I switch back to 3G it can find its location. GPS and WiFi work though.

Actually, YES! I'm an Android developer in Austin TX and the past 2 days I've noticed Network Location stopped working on 3G. WiFi and Edge work fine.
Luckily, there's a T-Mobile corporate sales office on the 3rd floor of my building so I went up there to talk to them. They had me write an email which they forwarded to their RF Engineers.
I got an email back last night saying the Sr. RF Engineer was experiencing the same problem I described and they said the issue had not been known to them until I brought it up. They are currently looking into it.
I tested on a G2x, 2 N1's, and a NS with the same results. I'm thinking the 42 Mbps upgrade has something to do with it, although you wrote this post April 5th......

yes i had this issue for about 2 weeks as well.
problem started when tmobile changed cells/towers around my neighborhood.
i noticed this because i used cellumap app which shows your cellid. it was different once the towers were changed. but the good thing is that couple weeks later, the location was available.
i had a hard time with the news and weather widget during the time of the unavailability of the location. it kept on pulling the information from a location near where i was working even after i refreshed meticulously. after rebooting the phone, news and weather widget didnt have any idea of where i was if i was using the new towers in my area. but all is well now.
so if this is still happening, most likely you're also undergoing tower changes. it should settle in a couple of weeks.
hope it helps.

3G No longer working?

I live in the Chicago area and am testing out AT&T service and the Tilt (thinking of switching from Verizon). Anyway, late last night the Tilt started searching for signal and could not find the Voice or Data network. I tried doing a hard reset... still nothing. When I got up this morning, it was still searching. I tried another hard reset, and now it is able to get on the voice network. The data network is working as well, but only as Edge, as it does not seem to see 3G capabilities anymore.
My question is do you think this is an issue with the radio, the SIM or simply AT&T's network. I was using 3G with no issues since Friday. The phone is brand new and was working flawlessly until last night. I did not perform any tweaks, or install any software other than Flexmail.
Your input is appreciated.

Dont worry, it could be just a network (provider) issue.
I got 3G signal at home, but sometimes (very rare) I got GPRS only
It will be ok
i am in chicago and all of today couldn't get on 3G, I hope it is network because I didn't change anything from when it was working till now
I don't think this is a network problem. For 2 days everything was fine. Now, mine does the same thing as eras2r. Works fine on Edge but when I am on 3G, it not only fails to connect for data, but it also kicks me off the voice network. Takes about 5 minutes or more to reconect. Sometimes it throws me out when 9n 3G area for no reason. AT&T told me to return, but since I was Premiere, I could only do an exchange. Total suck. Hopefully I get my new one and it won't have this prob.
Turns out it was a radio ROM problem. Need to make sure you are using:
ftp://xda:[email protected]/Uploads/Kaiser/Radio/KAIS_Radio_Only_1.27.12.17_CustomRUU.rar
I had 1.27.12.11 and it was killing me, but now all is good in the World!

[Q] 3G- no data, but GPRS, Edge & HSDPA ok?

I've had this problem with my Nexus One for as long as I could remember, but kinda ignored it - thought perhaps a new radio would fix it, or a new ROM...
But no, it still bugs me.
Basically, if the phone is on 'normal' 3G, I cannot receive any data. It just gets no connection. If I have HSDPA, or GPRS or EDGE - it all works fine.
But 3G? Nothing. And its EVERY time.
Travelling on the train every day, HSDPA isn't stable, so it often drops to 3G, but then it drops dead. I have to restrict the phone to 2G if I want to check things reliably.
I've tried every radio from every country from the original to the latest 5.12 leak.. yes, speeds increase, HSDPA engages more often, but as soon as I'm on normal 3G: Dead.
And I've tried all ROMs (original, MCR, Cyanogen, Desire, MIUI) - same.
Any build.prop tweaks I could find... same.
Now, I remember talks about this when the Nexus came out originally - but there doesn't seem to be any threads about it now, so do I just have a faulty Nexus One that I've put up with since Christmas last year?
Or have I missed something blatantly obvious that every else did to fix this problem?
Any help gratefully received
Pardon my grammar and spelling I'm typing from my phone without swype and its annoying. I had a similar problem. When on 3g I'd miss calls texts, etc...I had my boss call in my face and my phone didn't ring. It got so frustrating I turned off 3g for several months. Too make a long story short ....all those 3g problems went away when I 2.2 came out on xda I put a new radio and rom on. I can't tell u if it was the radio, 2.2, or if tmo had simply added new towers or improved signals from tmobile.
I'd call tmo see how your area looks and if there's any new towers.
I've been on 2.2.1, and 2.1, 2.2, and used all the radios that have been released.
All the same.
I'm in the UK and on Orange, and I have spoken, well, tried to speak to my network about it a couple of times, saying the fact that I've had this issue in the past with my HTC Hero, and I've tried every software update, radio, etc, but because the Nexus One isn't an Orange handset they blame that, Android, or the signal in my area. Yet, I can't believe its just 'Android', and it can't be all signal where-ever I go, so perhaps my phone does have a fault? I don't know!!
The common denominator between this and my Hero is the SIM card.. but convincing them the SIM is faulty is nigh impossible. I'm receiving calls and texts on 3G, and get data all the other times, so it can't be... can it?
Argh, as you can see, this is slowly driving me mad..!!!
Yours sound worst than mine. I used to have very reliable 3G data until upto mid October. After that period, there were numerous reports of Orange UK users struggling with data blaming (with high possibility) on merge plan with T-Mobile.
I tried SIM with my Hero and Nokia N82. All 3 phones suffer the same poor 3G connection and in places I spend my time mostly, all struggle to get any form of internet. Few months back on same places, all my mates were impressed by Orange's coverage.
Yesterday, out of nowhere I received a sms from Orange confirming that merged plan went well and customers are to benefit from all cell towers of both network. Couldn't stop smiling then tried to access XDA on N1's browser. Safeguard was ON and access denied. Tried to open few more, all same. Frustrated almost dialed 150 but couple hours later, all started as normal with H signal. No interruptions, no waitings and no error msg. Tested for almost 8 hours. Though still to confirm the reliability.
One more thing I noticed is that before I was using WM's AVS kernel. Almost always once in every 4 attempts, a msg would pop up on error connecting. Changed to SVS kernel and msg still would appear but very very rare. BTW, on latest Nightly.
Coming to end with orange contract and if problem continues, I'm moving to O2.
Try your SIM on other phones to see whether it's the issue with N1.
I might have the same problem. but this just came up 2 nights ago. while connected on data network, all is fine until it drops to 3G, app (opera mini) freezes and you will have to force close. restricted my network to 2G and all was fine. then a while ago i enabled again on 3G and all was fine again.
is this a sign that i may get your same problem soon?

SGS Captivate Got Signal. Can't Use Network

So almost two months of owning my Captivate that I got from Rogers (BNIB from Kijiji) and I noticed that at a certain area in my school, I have 3/5 bars of signal yet I can't seem to text/call and use the network. Is this a network problem or phone problem? Or can it also be my SIM? My SIM card is pretty old. However everything was fine when I use my Sony Ericsson W715 in the same area.
I should add that my friends on the same network beside me, they can text/call fine, which leads me to believe that this is a phone problem. A poster over at Howard Forums suggested network congestion, but it seems impossible because everyone else can use their phone fine.
I've tried different modems too, but it doesn't help. It's like my Captivate doesn't want to work at certain areas of my school.
A couple of people are getting the same problem as well where the phone reports good signal, but they can't use the network at certain locations. We're starting to think that this is a phone problem...

I noticed this same issue in fringe areas. I have ATT and in southern Utah they are quite weak. I wonder if the bars/signal are actually from another provider like T-Mobile or some off brand like alltel or something. Utah has a bunch of small providers in rural areas.
Specifically in my case I go up in the mountains at Brianhead Ski resort and i get 2 or 3 bars yet I cannot send texts or call. Verizon has coverage there and I heard rumor T-mobile had a microcell or something on one of the lodges.
Could the signal be from another provider that ATT doesnt have an agreement with? Or in the OP's case some provider besides his own?
That's highly unlikely though, the idea of my phone roaming onto another network. It'd show if I'm not on the Rogers network.
Plus, a lot of people use Rogers, such as my friends who are able to make calls and send texts when they are next to me while I can't at school.
Just an update. Switched to a new SIM card, no go. Got a reconditioned Captivate, still got the same problem. As always, everyone else around me could send and receive text messages fine.
Same thing happened to me twice today with the reconditioned Captivate, at two different locations. As usual, it happened to me at Ted Rogers School of Management on the 8th floor where it showed I had 3 bars and a 3G connection. However when I tried to send a SMS, make a call, or browse the web, nothing worked. Everyone else around me was fine though, so I still can't determine whether it is a network or phone problem. I already switched the SIM out for a new one too.
The 2nd time it happened to me today was just outside of the subway station. Keyword is outside. I wasn't underground. I had full bars, but again I couldn't use the network.

I still think it that in some cases our phones pick up out of network signals and show great signal strenght.
Maybe not in your case since others are working fine around you, unless they are bone stock maybe, and you have obviously improved your phone.
I did a bunch of expeirmentation with my phone, flashing different modems and such, trying to get an ATT signal at Brianhead Ski resort in Utah.
I could get the phone to show great signal on the bars and in settings/about phone/status but the service state and network would say unknown or unavailable, somthing like that. (maybe check those when you cant get out?)
I have since given up and reflashed so many times I dont remember which modem worked to give me good signal of networks I couldnt use.
I do know it was frustating as hell to have full bars and be unable to call or send texts.

Thanks for your insight. The other people around me have other phones, such as Blackberry, Samsung Wave, etc. I even tested it with my old Sony Ericsson W715 and my friend's Samsung Wave at pretty much the same location (a feet or two away from me) when I can't use the network, and everything is fine so it most likely is a phone problem.
When it shows I have signal, it also shows the service state, like I'm on the Fido network and such.

From no Data Problems to 99 Problems

So when I first got the phone I had zero connectivity issues. After about 2 weeks I started having very occasional problems with it taking awhile to re-connect to 4g going in and out of weak signal areas. Now my phone refuses to connect to a mobile data connection of any sort. W T F.....and of course this happens after having the phone for 38 days.
Running Liberty 3 2.0 atm w/ 5.5.886.
What is the latest official release so I can flash to it before calling and *****ing at Verizon?
idk bout the probs you're having other than you're rooted, etc, yada.
i'm still stock, no available updates, running sysver 5.5.886.XT875
Verizon is having nationwide data issues right now. Try switching to CDMA only. If I'm on CDMA/LTE it won't connect to any data but if I switch to CDMA only I at least get 3G.
I was thinking the same thing, I haven't had the data issues that a lot of people have with the Bionic. I was getting 34mbs download speeds this morning on 4G, then when I got to work, no data.....so I did all the known fixes, and still nothing, thought it was my phone until I read about the Verizon issue. Took me a while to get 3G running, but now it seems OK, just no 4G. Hopefully it will be back up soon.
Yup, the outage has been acknowledged by VZW. I think this is the 5th nationwide LTE outage I've experienced since purchasing the Tbolt on launch day back in March. It proves once again that VZW is very good at selling phones and not so good at running a reliable network.
I know that if the network where I work experienced 5 major outages in 7 months people would be fired. I'm sure the lower level engineers are hard at work fixing the problem but the Director or VP of wireless networks needs to go .... now.
As an operations guy who runs applications for a major health care system I know I plan changes in stages and must present and document validated back out procedures before I get to do the change. The change control process at VZW is SERIOUSLY BROKEN. I know what you network engineers are thinking .... someone fat-fingered a change. Nope, the severity and duration of this outage (and the ones before it) are a sign of much bigger problems.
I never thought I'd see the day where I seriously contemplated leaving a carrier because of network unreliability. Bad coverage is one thing but not knowing how to run a major network speaks to bigger problems.
Tried switching to cdma only first thing and no connection there either. Guy right beside me with a Samsung Charge was still getting 4g with 20mbps down.
For those keeping track you can add another data outage today. I'll echo my comments from above ... VZW is great at selling phones and not so good at running a reliable network.
Oh yeah, wasn't it Verizon that used to make fun of AT&T's network reliability? Sounds like they are following AT&T's footsteps. I just came back from Chicago which should be a strong 4G area, and I kept losing my data connection and my phone was already set to CDMA only. At home in the southeast I will occasionally lose data connectivity but not as bad a what I experienced in Chicago.

Is it my phone or the network?

I'm having a hard time figuring out if i'm having a phone issue or is it a network issue that I need to get used to. Simple tasks such as navigation I can rarely get to work if i've already started moving. It will act as if searching for service for 2 or 3 minutes before it gets a lock and will begin navigating. I have had times with AT&T where I had little to 0 service and navigation would pick up fine, but with Sprint I see connection lost a lot more. Is this a Sprint thing or you think I got a bad phone?
I will have 3-4 bars of service on 3G and can stream music but refreshing something like Twitter can take several minutes or timeout completely. I live in Atlanta and have rarely seen 4G/LTE which I believe to be strange because Sprint's coverage map indicates they have strong coverage most of the places i've experienced the hiccups.
What do you guys think?
I think it's a phone issue. I have it as well. ...at least the "GPS lost" issue. Didn't have it with my note 2. I get fast GPS locks though.
No issue with data except for sprints typical slowness
Sent from my HTCONE using Tapatalk 2
I haven't had that issue but I don't live near anywhere as large a metropolitan area as Atlanta so that could be an issue. My GPS locks are nearly instant but I do have problems streaming music sometimes.

I would call Sprint Customer care and tell them you are having issues with data services and that you have heard of this issue. Have them verify your UUIC ID number under settings/about/Phone identity. This is also the same as the SIM ID. They may say oh thats for international only but what they don't know yet is that number must match on your account for all your data services to behave properly. I figured this out after 6 phone exchanges.....the phone was fine....it was that number that was messed up.
My symptoms where:
- Slow data
- Dropped calls
- Radio was always using EvDo rev. A (check in settings/about/network)
- Never on EHRPD (Required for 4g LTE handoff with the towers)
- 104 data errors (these still happen but much less and is because they are still building out the 4g network here)
I hope this helps and will fix your issues. It did for me.
