Still having data problems. No 3g/4g!!

This is really becoming frustrating. I switched to Verizon a week ago and had 3g/4g service for a couple days and now NOTHING. I called support (12/23/11) and after an hour on the phone, visited the store. Then after 2 hours at the store where they switched over the SIM card, gave me a brand new phone, and still having problems with the phone. So I had to open a trouble ticket to look in to my problems with my data connection on my Galaxy Nexus. According to the store, support said I am the first to call about the problem.
Store rep was on a 4g HTC phone...his data was fine. My mom is on a LG 3g phone, her data is fine. All in the same areas of town as well. Why isnt mine? Tried CDMA only and nothing as well. For about 10 minutes, I had a 1x data connection that was slow but it worked. No nothing, again.
If I got a new phone, new SIM....then the problem is with Verizon somewhere and needs to be fixed. I am paying money for something I do not have and its a waste. I understand there will be problems from time to time, but don't release comments saying the problems are fixed when there are clearly still issues.
Anyone else still experiencing data issues specifically with the Galaxy Nexus?

Was a nationwide outtage Verizon said was resolved a couple days ago. Was working fine on Monday/Tuesday. This isnt related to the fix to resolve the reception problems. I can text and make calls just fine.

Try disabing vzw backup amd google +. Stopped my phone from doing exactly what you describe.

I've been having the issue where the hand-off from wireless to 3g tends to cause me to have no data connection at all (wifi shows up, but can't 'do' anything like browse to a website and such, and 3g never makes a 'connection', but I know I'm in an area where I should have plenty). A simple restart of the phone fixed the problem, but in the long term, I shouldn't need to do this in order to get a data connection. Just my experience.

I had the exact same problems. I returned it & reactivated my Thunderbolt. I hope Verizon actually fixes the radio instead of just changing the number of bars that get displayed. My lack of faith in this is why I returned it before my 14 days ended. I hope they will actually fix it & I'l try again in a few weeks. You might consider the same strategy.
Also, I had bad data & signal before Google+ was even on my phone.

Everyone isn't having problems. Verizon's fix is just going to change how the bars are shown.
If you are having this many problems, just exchange the device until you get a new one.

I kinda doubt they are going to keep swapping out my phone over and over again until I find a working one. My original phone worked fine fora few days and probably is still messed up from the recent nation wide outages they had. They were hesitant on replacing my phone the first time.
Going to call support in a little while and follow up on my trouble ticket I logged yesterday. They better have a solution for me.

You paid $XXX for this device and you're afraid they aren't going to give you a new one because this one is defective? This issue may seem widespread because of all the complaints on this forum, but trust me, not everyone is having issues. Check my other thread.
Verizon already came out and said there isn't a performance issue with the device and their patch is just going to change the bars. So it's now or never.

Are people having slower 3G speeds on their CDMA devices? This is my issue as well. My sister's iPhone is consistently getting 1mbps> whereas I'm only getting ~100kbps down. Upload is worse at 47kbps.

I already got one new phone replacement yesterday. Going to call support yet again here in an hour or so and see if they have an update on my trouble ticket. But I would think it if was a defect in the phone, that this issue would be well known by now and posted everywhere on the internet. I understand what you are saying....just hope they get it fixed.

I'm having this problem too. I'll be on wifi at home, both wifi and cell bars will be blue. Everything is dandy. Then when I leave and turn off wifi the 3G icon appears and I have a few bars, but they are grey and websites don't work. I thought blue/grey just meant you are/are not logged in to google services, not whether or not you have data connected in general. A restart solves the problem, but it shouldn't come to that. This was a problem before the outage as when they were setting up the phone on release day in the store it took awhile to connect to 3G. Is this also why when I switch in to airplane mode I can't come out of it without a restart?

Unable to register to network problem.

Anybody ever have this problem? My phone had been working well for the last 5 months and now it is unable to connect to tmobile. I replaced it with the new sim and it still has the same problem. Placing the sim in another Tmobile does work however.
I am still unable to connect using Juggernaut, All the ICS roms, etc.
Even Odin back to stock and it still doesn't register to the network. I look at the APN settings and it is clicked for Tmobile.

Sounds like the device is blacklisted. Where did you buy it from ?

Yes it was blacklisted. I got it unopened from craigslist. Tmobile blocked it after i have been using for 4 months.
They won't tell me why or how to resolve it. Oh welll . I lost money on this one.

I have a Galaxy SIII sitting in front of me that I have to get the seller to refund my money cause of this problem. Tmo says the phone was reported as not received after ordering. I guess when they do that, they block the IMEI and won't unblock it for anyone but the original seller. I guess after they pay for the phone.

3g/4g Drop calls

Bump. Any help guys?

I have the Verizon and have been having the same exact problem. The signal will randomly fully cut out on my phone for a short period of time and it's ridiculously obnoxious. Does no one else have this problem?

I contacted samsung and they don't want to replace my phone.. this really aggravates me!

Have you tried calling Google Nexus support directly? Since you just bought it, they should be able to help. When I had an issue with my phone, I called Google and they transferred me to Samsung for a warranty claim. Samsung reps did not speak English very well and basically told me to call Google back to troubleshoot. I called Google back and explained to them what Samsung said and the Google rep was adamant Samsung would have to honor my warranty. He offered to 3-way call with Samsung and explain to them the issue and why they should do a warranty claim for me. In the end, Samsung ended up agreeing to fix my phone, but I had to send it out to their Texas factory, which took about 4 weeks total to get it back. So, I would try calling Google and see what they have to say and maybe they can help talk to Samsung about repairing your Nexus.

Yes I contacted Google and they said the same thing.. I can't send this phone in because I don't have another phone I can use.. I put a new sim card in my phone, I'll post whether it works or not soon.

It's a device issue. I have the verizon one and it was suffering the same problem I had to send it to get another one and now its working phone with no data drops(knock on wood)

Tmobile Note 2 no network circle crossed out

Hi and thanks for any help that you can provide me.
I bought an Galaxy Note 2 SGH-T889 Tmobile version like 7 months ago from a store or reseller in Toronto Canada, the phone was in theory factory unlock, to use with the Wnmobile network which uses the same frequency as Tmobile. The phone was working until 2 days ago. Well always the phone has issue connecting to the network in some specific areas, specially because the Wind network it's not that good, but during the last 2 weeks I noticed more and more problems and some times it was just disconnected showing a circle with an slash or crossed out. After reboot the phone usually fixed the problem, until 2 days ago I had to do it every 2 hours and then the next day it just was permanent. I tried everything so far:
Remove battery and reboot
Remove battery and SIM card and reboot
Use a diiferent SIM card from my son's phone
Replace for a new SIM card
Clear Cache
Factory Reset
Reflash the modem with Odin
The phone has the latest stock ROM 4.1.2, BASE T889UVBMD1
The problem is Samsung say because it's a Tmobile they can not support it here, I have to send the phone to Samsung USA, I still fighting with the store because they said it will be covered locally, but that is another story.
I red many post talking about similar problems with the Galaxy S3 or S4 and one said that installing Jedi X14 fixed the problem, but to do that I think I have to root the phone, which not be a big problem.
The other weird thing is the phone works using other SIM card GSM, not tested with a LTE SIM.
There is any way to test if the radio/antenna for the WCMDA is disabled or broken
Thanks

If the phone is working fine with a friends sim card . There is nothing more then a issue with your sim. go to the store and have them to give you a new sim card or flash the one you have. I had that issue similar here with at&t all the time.. sims would just loose network.. The fix for me LEAVE AT&T
Good luck.

Yes, I replaced the SIM card and I got a new one.
Just trying to eliminate all the options, I just did a factory reset again, and put it back the SIM card, located outside in an area where I know there is a strong signal and the phone was able to connect to the network and I install the account ans the apps just to test the data connection and it works fine. I was outside for 20 minutes with no problem. Later go back in the building, as soon I was inside for a few minutes the phone lose connection and the circle is back, then reboot again several times, and the phone does not recognize any network, Searching and no network is available.

Aww you left out that it only does this inside but works outside.. I Would say something is blocking the signal. LIKE maybe the building..
i have two bars in my house 3 on the deck and full signal in my yard ...
its just how it is..

But he said it was working in side for many month then all a sudden it doesn't work? I understand I live in a mobile home and reception sucks but that from the start but his was working for couple months. I would say he's phone reception receiver w/e it is or something in the phone is screwing up and it will need repairment or replace or service just taking a dump and getting worse.

You could be right.. or maybe even the provider having issues with that tower .. its a tough thing to figure out..

Thanks for your ideas.
I get tired of trying to figure out was is the problem, so I got a SIM card from a diiferent provider which has the best network coverage and power, and i'ts happending the same, the majority of th etime the strength level is around -110 db even outside, with both providers, so it's the phone.
Now the question is could be possible that the antenna cable got disconnected or broken, (yes I dropped the phone a few times but nothing major) and it was working fine until few days ago. Another option it's some internal hardware is not working normally.
Now I have to find a way to repair becasue Samsung Canada does not want to do it becasue its a Tmobile phone.
Thanks, again.

Anybody with same provider as you? Invite them in you're home see if they have connection. It's best if the person have same phone and same company. Can you send directly to Samsung? I have bad phone service my area with s2 and note 2 but my friend with evo 3d has more bar then me and its made by htc but could be two things ur phone crapping out on you which need repairment or like the guy above said tower signal getting weaker. It is hard to find out. Maybe for now for a bit since it's screw up try a rom but then again rom doesn't control radio settings section but wouldn't harm. Good luck.

I'm having the same issue since last month... but with any SIM card.
The network signal strengh rests between -89 to -110 dBm. (Horrible)
The network type is always UNKNOWN:0.
What I already tried:
- Using other SIM.
- Flashing Stock ROM
- Flashing Custom ROM (CM 10.1)
- Flashing all 5 avaliable modems.
What happens:
When I get VERY close to a network antenna... I can make calls and stuff...
What can be happening:
Hardware issues - T-Mobile latest LTE unlocking update maybe burned my antenna (or some network signal related hardware).
Software issues - Can't see how since I used many variations of ROM/Modem.
I live in Brazil and my network is TIM 47. I have a Samsung Galaxy Note II T889.
If anyone can confirm perfectly to me what composes the T889 antenna components... that would be nice...
I want to buy those parts from eBay and trying fixing my phone.

Thanks for your feedback it's really valuable becasue it's almost the same situation. Today I cleared up the situation with Samsung, if I want to be service under the warranty I have to bring the phone to one of repair centres in USA which it's kind of problem because I can do it only in the weekends but not impossible or what I'm doing tomorrow is to have an assessment by one of the repair centres in Toronto and I have to pay in this case, if it's something reasonable.
In my case I did not update the phone in 2 months at least so it's not software in my case, but one difference could be I got a new job 3 months ago, in my previous job the majority of the time I got 5 bars , I guess the cell tower was close to that place, and in my house the coverage it's good. In my new job, my office it's in the middle of the building, far from the windows, so the signal always was really bad, 0-1 bar.
Wondering if could be possible that a bad connection can burn the antenna or the circuit that controls the connection.
The other thing is there are many customers specially for the Galay S4 complaining about a similar problem, and I did not find any answer on how to fix this problem.
I'll post any update just in case it can help someone else.
Thanks.

A also have this problem with T-Mobile Note 2 and have already tried everything you guys have...I guess I got no choice but to request a replacement which sucks because my phone was pristine and worked perfectly otherwise. It's just the damn weak to no signal that's driving me crazy. Especially since I'm paying for premium data coverage and it's pretty much money in the trash every month.

That's it. I made the call and the replacement arrives in a couple days. They offered me the "jump" program. Anyone on that? Is that worth doing on T-Mobile?

I traded an unlocked i317m for a g pro. I just picked up a unlocked t889 as welll. The person with my old i317m want my t889 since hes using simple mobile. Problem is when I went to trade I put his sim in my t899 it wont register on tmobile. Seems its only working with at&t as thats the service I have. Now with the i317m I gave him originally it works with any sim. How is this possible that a unlocked tmobile t889 wont register with his sim on tmobile network but the unlocked i317m works with any sim?

Yesterday I replaced the microUSB module that is connected with the antenna and replaced the SIM card module too.
That did NOT worked.
So... the problems is problably on the mainboard/chipset... too expensive to fix.
Another big hardware failure for Samsung's history.

I've had the replacement for about a week now. So far no signal problems. It's like when I first got my original phone. I'm sticking with the note 2 for at least another 6 months since I joined the jump program. Can't wait to see the note 3 next week

Update just to close this case
Well, after I sent the phone for repair to Samsung USA, I got it back and the problems happened again after a few days, then I sent it back for the second time to Samsung, got it back and the problem happened again after a few weeks. Basically, I'm getting rid of this phone, now the warranty is already expired and half of the time the phone was full of problems with the network.
The lesson in this case is to avoid getting hardware from the first batch (to wait a few months after the launch) or without a long term warranty (3 years), and probably will be my last Samsung device.

Anyone having problems w data drops?

I just got this phone and im having problems w data connections. I had it rooted and then went back to stock. Still same problem
Spoke to TMobile and they said they will reset my account in their end. Wait 3 days and if still problem they waive restocking fee.
I like the phone but thinking of exchange for S5 if this is a common issue w G3

could be TMO issue....if you new to TMO...their coverage not as good as verizon.

This has been documented with the G3 and Tmo, where it says it's connected and has a data connection, but nothing is being sent or received. You either have to reboot or go into Airplane Mode and then back and you get the handshake again.
I had this problem during the first few weeks of getting the G3 (and also Tmo service), but lately, the last two weeks, I haven't had this problem either on my phone or my wife's G3, which was experiencing the same problem. Perhaps it cleared itself up or Tmo found out the problem with their G3 handsets, seeing as it was just released then. Also, I haven't seen any OTA updates, so it might be on Tmo's side.
Others have mentioned they experienced the same thing on Tmo service with their Note 3 or S4, so it might be a Tmo problem with their handshakes.

Yes thats the exact problem I'm experiencing.
So your phone corrected itself after a few weeks?
I've been on T-Mobile for years and last phone S4 and no problem

We haven't received any updates, so I am assuming it might have been due to the G3 being just introduced on the Tmobile network and kinks were being worked out. Both of our phones are rooted, BTW, but I doubt that makes a difference, as others who had stock were having the same issues.
But, I had just joined Tmo with the G3, coming over from Sprint, so I can't say how the experience was before the G3. But on other threads here about the same problem, other Tmo users who had other phones (one being the Note 3) before using the G3, said they had the same problems with the data connections.
