[Q] No reception

I rooted my G2 about 2 weeks ago with Virtuous ROM and, the other day I picked the phone up to go to work not thinking anything was wrong.
When I got to work, I had an X where the signal bars are. Tried to turning phone off and, nothing.
When I go in and search for the carriers it shows T-Mobile and AT&T listed then I tap the T-Mobile section and it tells me "Your SIM Card doesn't allow connection to this Network"....So we called T-Mobile and switched SIM Cards and still get the same thing.
My SIM works in every other phone we have, including our myTouch4g...I have un-rooted and, same result. Then rooted again and, it still acts the same way..
T-Mobile said it was something with their network and, could take 3 days to get it straightened out.
Has anyone else had this kind of problem out of there G2 before or after rooting?
I'm in Tennessee, if that helps.

Well, I went totally back to stock and, still no reception. Just an X in the signal location.

Send phone in for warranty if you have it...and try to enable raoming and data raoming and see if you can pick up any signal...

Thanks. I tried that and, still no signal. My DBM is -109 when I checked it a few minutes ago through the my device app.
Checked it again and it says -89, signal strength of 14 but, still have an x on the signal bars.
This is crazy. You don't think the Virtuous ROM messed it up do you?

I got a solution from T-Mobile. They are sending me a new one.....YIPPIE

[Q] Thinking about exchanging my CDMA GN due to LTE signal drop

I've been using the Galaxy Nexus for about a month or so and have recently started to notice that the 4G signal will drop whenever I turn on the screen after some time in deep sleep. The signal meter will be fine, until I actually try to use some data. It typically takes about a minute to reacquire a signal, but the phone is essentially useless during that time.
As you can see in the screenshot, there are several red spots where the signal dropped out. I am not in a poor coverage area, and others with the same device do not have these issues. I saw this with a rooted 4.0.2 OTA and am still seeing it with a rooted, deodexed 4.0.4 rom (http://forum.xda-developers.com/showthread.php?t=1481613).
What do people think? Will exchanging the phone possible fix the issue? Is there anything Verizon can do to try and help me out? I'm basically just spitballing here, but this problem is making my phone very frustrating to use.

Are you rooted or stock? I don't have any issues with my 4G on stock or rooted with Gummy 0.7.6. I had an issue with an earlier root where my 4G would drop. I would disable / re-enable and it would start to work again. Maybe try rooting if you are not rooted????

Yes, I see this on rooted stock, as well as the ROM I referenced in the original post (supposedly deodexed 4.0.4 stock ROM)
EDIT: From several posts in the other thread, this issue is not isolated to me or my hardware so I probably won't bother exchanging the phone.

History of Signal ?

Can you please tell me where you get that HISTORY screen from. Ive checked all menus in settings and I can not find it anywhere.
EDIT... Please ignore my post... I found it...

So, I'm having the same exact problems but i did a log cat to see what might be culprit.
I have narrowed it down to this:
02-08 11:21:51.912 E/IMSFW (415): IIL: Disconnected from '7467' socket
still have no idea what can cause it yet.
also if you switch to 3g it seems it doesn't happen so maybe its a sim problem on verizons lte network end?
11:22:40.029 E/IMSFW (415): ImsSMSInterface: Registration failed, go for retrying if isim nounce present
that's what i found so if anyone can clarify and maybe see if it is really on Verizons end as this is the 4th phone that has had this problem.

Hey fellas, I'm posting in this thread because it relates to the issue I'm facing. Coming from the Thunderbolt, I had no problems holding onto a LTE signal in Atlanta, but with my GNex, the signal just drops a lot (every half hour or so maybe), at work, at the store, wherever. It shows an empty signal bar with a small x, and says 'Searching for Service'.
This seems to happen only when I have it in LTE mode. I switched to CDMA under the 'Mobile Networks' settings window, and it was able to hold on to the 3G signal all day. I am starting to think if it is a LTE sim card authentication issue.
I'm going to VZW to see what I can do (I'm still within the 14-day window).

I'm having the Same issue holding onto a 4g signal in Savannah and Atlanta, cdma only is fine. Let me know what Verizon tells u cause they basically told me to wait for an update

Just came back, basically they said they can't do anything unless they replicate the problem, which they couldn't. (it was a random problem.). They told me to call customer service when I got that issue, so I have to see that at work tomorrow.
I tried a suggestion online where I updated my prl from the 15xxx version to the 52642 version. I did this by creating a contact with the following number
*22899
and dialing that contact. It went through a 'activation' process, with some elevator music, and the signal seems to hold.

I've updated to 4.0.4, 4.0.3, flashed just the radios, removed some card, hard reset, factory reset, just about everything u can imagine and still no luck. I'm tempted to file a claim with asurion(purchased gnex from a friend) and see if another gnex works with late but I don't wanna spend $99 for nothing

To this and post 10, I still have those data issues, but they are much less frequent on the 4.0.2 radio than the 4.0.4.
I got in touch with Verizon wireless online support, and they basically told me to wait till they release a software update. I asked for a new sim card (since I thought it might be LTE authentication issues), and they said it was a software problem, not a SIM problem.
I guess its a wait and see.

weak signal galaxy note 2 t889v

HI,
I have a very weird problem with my phone... and don't know what the cause of this problem is. One day I woke up, and had terrible signal on my phone... it would show 2 bars n Edge on the top. Then have no service at all. So I factory reset my phone and all that good stuff and still have the same problem. When I'm at my other house, I have 4 bars and HSPA+... at work I have no service at all.. When I'm in my car... it goes from no service to full service and so on... I know it's not my sim card cause I tried it on my Buddy's note 2 and it works fine... I haven't done anything to my phone but unlock it so I am able to use my videotron phone with my Fido carrier. Other then that I haven't done anything with it. I have tried every single thing on this forum, except changing the signal antenna... Does anyone have a solution? And I can't bring it to Videotron cause it's unlocked...
PLEASE HELP
Thanks in advance!!!

Hey! Thx but I tried using the my friends sim card on my phone and it works fine... and vise versa... So it's not the carrier or the sim card... Its the actual phone itself... Someone told me to put a custom rom on it... but I kind of like the stock rom that comes with it. I purchased a signal antenna and will try that out when it arrives...

Just an idea, check your network mode through settings/mobile network/networksettings, maybe it has been changed. Or you can try *#2263# in the dial pad and see if it is set right also, I think it should be WCDMA All. Like you said it might be a hardware issue, but no harm done in checking these.

I'm waiting for Tmobile to send me a new phone for my wife.. Same problem.. And it just keeps getting worse.. I have spent hours on the phone with them and nothing helped so they agreed to send me a brand new phone

I have this exact same problem! No service at my house but my wife's note 2 works perfectly sitting right next to mine. Service is all over the place when driving around. Sometimes it will even show bars (service) but it's still searching for the tmobile network. But mostly the service is all over the place or not at all. The wifi calling feature works great and thank God for it, or I would never have service. I have since done a couple things to try to fix it. I have replaced the antenna module in the phone (its the part on the bottom back that has the loud speaker in it), I have rooted and flashed a new rom, as well as flashing several tmobile modems. Nothing so far has made any difference! I am beside myself as I have no warranty and no chance of returning it. Please please please someone help us!

Life saver for me with that dial pad code. Thank you!
Recently switched it to only 4G and when in bad signal areas, phone is useless and couldn't remember that code.
Stored that sucker into contacts, lol!
Appreciate it, going on a trip and need phone for navigation.

Which one did you set it to for it to work for your T-mobile, I have the same problem.
I thought T-Mobile is GSM, not CDMA? I wonder why it worked for you?
Which option did you set in that menu? Thank you.

Just wanna say thanks to you... Was having piss poor signal after switching roms/upgrading to 4.3 and had the worst signal as in before it was great. You gave me the idea to check networks.. it was set to use lte/wcdma/gsm.. I changed to wcdma/gsm only. Now I have all bars back.. Thanks!

WCDMA is a data protocol used on GSM carriers for 3g (pseudo 4g) service.

Does that mean if you switch it to that mode, you can't get LTE?

Do you get LTE service?

I have exactly the same issue. Replaced the USB port board and since then I have terrible signal. I ordered new antenna wire and replaced it, but it did not help. while driving the hpone is balancing between full bars and no bars. At home bu my dest where I used to have 1-2 bars I have no service at all. I restored factory settings but it did not help. I'm sure it is not the service cause this same SIM works fine on another phone. Of course T-MOBILE (I use SOLAVEI but it is based on T-MOBILE network and service) is of course GSM so setting phone to CDMA makes no sense.
There are 3 connector pins on the plastic frame piece which is removable. One must remove that frame to get to the antenna or other pats (i.e ribbon connectors). I 'm not sure what is the role of those connectors or if they have anything to do with antenna or signal strenght/reception. Any ideas ?
IF ANYBODY MANAGED TO FIX THE PROBLEM (especially for Note-2 T_MOBILE phone) PLEASE SHARE IT !

Problem seems to be with the gsm radio you can select gsm only and see if you get any signal if not its the gsm radio but I don't know how to fix it

Try to wash the sim card carrier by jupiter oil . Tried and worked well.

[Q]Unlocked T-Mobile Galaxy Note 2 on AT&T

I looked everywhere and cannot even come up a guess to my issue. I have an unlocked T-Mobile Galaxy Note 2, but switched carriers to AT&T and now having weird issues with the phone. I changed the APN settings, but I still get network drops during phone calls and syncing issues with phone numbers.
The phone will randomly drop a call and not be able to call back for about 5 minutes. I am not a noob and I can usually troubleshoot my own issues. Oh yeah, the phone was working fine on T-Mobile and only started the issues when I put a fresh AT&T sim card in it. It doesn't happen all the time either. I could go a week no problem, then three or four days with issues.
Any suggestions on what I should do?
Thanks a ton

I have two TMobile Note 2s that work just fine on ATT. No dropped calls and data works fine. LTE reception seems a little lacking but other than that it's fine.

Try a new SIM.
How long have you been on AT&T? Post paid or a MVNO?

It's actually my sister who has the phone now. I was using it on T-mobile with no issues. I gave it to her, then it started having these problems. Goes to and she gets a brand new at&t sim, still doesn't fix the issues.

Signal cutting off :(

hi all...
currently using tmobile galaxy note 3 with an at&t sim. the phone is in good standing. not blacklisted. i love the phone. currently using slim rom (latest). ever since i got the phone, i been having signal issues. there are times when the phone signal cuts off, no signal at all. and then there are times when, even though, it shows a signal no one can call me, it just rings or cuts the caller after a few rings. sometimes my gf would tell me shes been calling me, but i never got any calls/miss calls. sms would go through though. and when this is happening i would try to call a number, nothing happens, no ringing, no sound at all coming out of the earpiece. a reboot would remedy the issue. but its starting to get annoying.
can anyone help me out here. am i the only one with this issue?
thanks in advance.

wondering if i should install a at&t modem. can anyone tell me if that is a good idea??

are there any hardware differences between the ATT version and the T-Mobile version? I have not done the research, but it is possible that the ATT version does not have the correct GSM/LTE bands to get a good connection on T-Mobile.
I had similar issues using a Verizon Note 2 on T-Mobile and AT&T

I have the same issue. I even tried redoing my apn's and the problem continues...

I have issues if I don't use att after day and use tmobile it won't load data just voice, I turn it off and switch sims and load the data, turn off, switch back to att sim all is well.
