[Q] phone unable to connect to mobile network

hello everyone,
I have my GSM galaxy nexus running aokp_maguro_milestone4 , 3.0.8franco kernel and xxkl1 radio baseband. I used to have no problems with my phone at all until I went on vacation to Spain (I live in Germany) in Spain I had signal but ever since I came back my phone has almost (in the time span of 48 hour it had maybe 1 hour of signal) constantly no signal from my mobile provider (BASE). I have tried reflashing the radio ( I had xxkl2 so I reflashed that and then flashed xxkl1), I have also tried turning phone off and on and leaving it 1 night without battery. any help??
thanks

Check your APN settings, if they are correct try to make a new APN profile from scratch.

checked apn and they were OK. made a new apn with values I found online and still no luck? should I maybe just restore everything to default and flash the stock from?

APN settings are only for data. They do not impact signal.
Go to Settings->More->Mobile network settings->Network operators and either select "Select automatically", or pick one from the list.

Just a suggestion but maybe a whole different updated ROM flash might do the trick

Like using a sledgehammer to kill an ant! :laugh: That should work as well.

Lmao I know but sometimes its just what's up. He didn't mention the ROM he's using. If he's that worried about this then its definitely worth a try. Like I said, just a suggestion. No need to slay ants over it

Swiftkey'ed on my CM9 Galaxy Nexus

Hi guys,
So I am still having this problem, but an interesting thing happened. I decided to stick the sim card of my gf (she uses another carrier which supposedly uses the same infrastructure as my carrier) and I had full coverage. After that I changed the sim again and had coverage on my line, but after a couple of hours of bad coverage it just never found signal again.
So what on earth could possibly be wrong and what can I do to solve this problem?
I would consider a new ROM, but this doesnt seem to be the problem.

Maybe you should contact your carrier and get a new SIM or check if there is any known problems in your area.

No 3G data on my new SGS3

So I got a new SGS3 and it works fine, except when I am in 3G. When I am in 3G I can receive and place calls but no data. Att support was no help, so I figured I would check here. As far as I can tell it is either a APN, Gateway, or Account settings issue (the later being something I can not do anything about). I say this because my n1 gets signal fine here, and it seems to run fine, so long as it is 4g.
Any ideas? Also, does the SGS3 have EDGE support?

Bump: And also I tried to set an old APN but that didn't help.

Have you rooted and flashed it or are you stock? If you are just stock...there is nothing this forum can do to help really.

I have not rooted or anything, I have tried some APNs but I was hoping other people might help me out with something else to try. I don't really buy the whole " if you are stock... there is nothing that can be done" What if I was trying to get help with a stock developer build of my n1 (which I have previously) or are you asserting that without rooting I will not be able to fiddle with the modem settings?

What I'm saying is the phone comes ready out of the box. Unless you have changed something then it is a network problem. You will have to take it up with AT&T.

U can only do so much stock....and thats not alot! Root and use stock rom so u will have root access to see whats what...and to be able to control what u do or dont want ur data to do

Thank you guys for trying to help but I know all this. I am just in the period of time I can take it back and I don't want to risk that by bricking it while monkeying around.

I (Maybe) have isolated the problem, they said that I was set up for LTE and there are some issues with proper propagation of properties. Anyway problem "May" only effect people on ATT with Samsung S3s bought at BestBuy locations and the upgrade includes unlimited data. Still working will update tonight....
BUMP!

HELP please...Problem regarding very poor signal after root?

Hello. I finally decided to root my galaxy s3 a few days ago. After I did so I downloaded some themes, ad block, etc. the normal stuff. The next day I started noticing something odd with the phone, such as very poor data connection (I can restart the phone and it will say I am on 4g for a minute or two although the connection doesn't say the same, but then it will either go to EDGE or give me no connection at all.) and poor network (says I have good bars but texts don't send often and take 10 minutes to receive; phone calls drop.}
I took the device to the AT&T store and got a new SIM card and that did nothing. 45 minutes of "support" did even less for me. I unrooted it, factory restored it, nothing.
I am desperate, if anyone would give me a workaround / fix, it would be greatly appreciated. Thanks.

Not sure. Did you check your APN settings? Did you flash any ROMS, modems or kernels at all?

I don't think so...I did everything this tutorial on galaxyroot told me to do...would link but can't.
Sorry I am not too experienced with rooting
APN looks fine...Then again I don't know what I am looking for lol. It says ATT PTA and it is checked.
I did have apex launcher I don't even know if that was a rooted app though lol..........

Thank you, now for the QCN..........I will be very happy when this is fixed lol.

So whenever I try to create a QCN I am unable to find it in the location I placed it, and I have hidden files visible. When I try to slide it to a different folder it says the file doesn't exist anymore. My phone has moved to "Unspecified" in devices and printers and I am unable to access any of its files even after trying to reinstall drivers multiple times (it gets stuck on the 5th one...network something...). Does anyone have any suggestions on how to resolve the problem with not being able to access my phone?
Ok I figured out how to access my phone and I think installing a new modem fixed it.....we will wait a couple hours and see.

OMG! (Anyone???) samsung gn2 networks prob

I have a sprint samsung galaxy note 2 that is rooted and flashed to verizon running macksrom 5.0 and i started having this problem. the problem is i can call from my phone when it is not on wifi but the 3g/4g isnt showing up top in the status bar i cant access the internet unless im on wifi. when i go into settings and click on mobile networks it acts like it is going to do it then it hangs at a black screen and a box pops up and says unfortunately, the process com.android.phone has stopped ive tried cleaning caches and fixing permissions, nothing helps, there is also another thing that pops up and says error #89 unknown error. it also says when i click on stuff, use touchwiz or xperia to perform this action. Always or just once.) I bought this samsung gn 2 online everything was already done to it. I think whoever installed the macks rom must have left the the touchwiz on it. Because it keeps asking me when i do things, perform action using touchwiz or xperia I also noticed that i have goomanager on it. Can i use the goomanager to reflash this phone? If so can someone give me information on how to properly do it. i also read something about mobile odin. Which one would be the easiest to use?

You have too much going on there. I would relash the rom. Make sure you wipe system, casche and devick; may want to do old school and wipe three times.
Goo Manager is probably suppose to be there, by design from the ROM developer. That should have been in the OP on the ROM three, along with known issues.

Doesn't verizon run a slightly different hardware version from sprint? Are you trying to connect to the verizon or the sprint network? If verizon, there are two possibilities. 1 - hardware, the sprint phone just doesn't like the verizon signal. (unlikely) 2. - ROM, is the ROM the sprint version or the verizon version? if it's the sprint version I would say that framework differences are causin the issue and would reflash the correct version for your carrier (or the correct port - the hardware differences I mentioned earlier)
Have you called customer service about getting your phone set up on their network? About getting the IMEI number registered in their database?
In other words what have you already tried with this used phone in order to get it set up on your provider's network?

it was originaly a sprint phone that was rooted and flashed to verizon. ive been using it for months on the verizon network and have had zero problems until about five days ago. i dont know if the rom is sprint or verizon. how do i tell? i would reflash it if i knew what i am doing. i am a complete uber noob. im just hoping someone will give me directions how to reflash it. i dont care what rom i just want it to work again on the verizon network. i want to be able to use it to go geocaching with my sons. just got it all set up ready to go caching with em and the very next day it decided to go mental on me.

I would check out the thread on taking the Sprint GN2 to TMobile, Verizon, Boost, and Ting. I think it's in the question and trouble shooting subforum.

I don't know personally, but I believe so. You'll have to read and ask in that thread. Those are people who may have done the switch and can give better advise from experience.

[Q] Strange behavior on Data

I have (purchased 4mo ago) Tmobile Note3 phone on prepaid tmobile unlimited $70 (with 4G LTE) with Kitkat. Sometimes even with 4-5 bars with 4G sign it looses the data connection. Browsers wont load pages, email client just trying to sync. Google play's circle spinning and spinning. Everything works again after few second/minutes and stops again later. I did a factory reset and didnt help. Anybody know whats going on here?

So is everybody with Kitkat having this problem?. Could you please show where it mentioned that it will be fixed in 4.4.3?

So we will have to wait for 4.4.3 update, anyone knows when will it be available?

Yes known problem with kit Kat.
I have it myself

I have wondered the same thing, I'll have all bars but Web page won't load, can't load the play store. It happens a lot , more then just a hand full of times, but now I'm running with hyper drive rom and so far so good. We'll see.

I hope this issues would be solved next update

Ok guys, try this, go to your Mobile settings and change your APN's IPv6 to IPv4, its gonna help a lot.

how do you do that?

Try this
Settings > More networks > Mobile networks > Access Point Names
What to change? APN Protocol? or APN Roaming Protocol? Thanks!

Both, but is not a fix

I didnt have any data drop from y'day after changing the APN. Data looks little bit slow though. But batter than dropping. Lets see how it goes.

I have mine set at both IPv4/IPv6 and I had a major improvement with all bars and poor speed.

Any updates or solution about this?

Do you need to have root acces for change the ipv6 for ipv4. I have all original and do not give me acces for to change the protocol to ipv4.
