Galaxy Nexus cannot send/receive voice calls or texts, can browse internet with 4G data.

Question:

Is my CDMA radio dead? Can I replace it? Should I just replace my phone?

Issue:

On 9/20/13 around 10 PM my Galaxy Nexus suddenly stopped accepting/sending voice calls and text messages. The status bar displays a no signal icon and when trying to place any call it says “Mobile network not available”. It will not place utility calls to Verizon and won’t even dial 911. It however still retained a 4G data connection as I could download apps browse the web and watch YouTube videos. I even tried Google Hangouts and a Skype video call both functioned fine. I confirmed that Wi-Fi was disabled and this occurs at multiple locations including ones without a Wi-Fi network. There is a valid 4G IP address listed under the Status menu.

Stock Android 4.2.2

Network: Searching for Service

Signal Strength: -109 dBm 31 asu

Mobile network: LTE:13

Service state: Out of service

Roaming: Not roaming

Mobile network state: Connected

Troubleshooting steps:

I tried powering it off and back on. Then I pulled the battery out and next pulled the SIM can and battery out then powered on the device without the SIM. Without the SIM it still showed the same no mobile network available and data was unavailable. After replacing the SIM data returned but voice calls did not. I even tried a complete factory reset of the device and while 4G data is working great I cannot send/receive phone calls or text messages.

Verizon Support:

The following morning I called Verizon and spoke with Level 1 and Level 2 Tech Support. They had me run all the troubleshooting steps possible and came to the conclusion that it was a cellular engineering problem. They stated they would contact me back within 24 hours with a resolution. 24 hours came and went and still nothing so I called Verizon Tech Support back and spoke with another Level 1 and 2 Tech and repeated some of the same trouble shooting steps. They apologized for the inconvenience and were confident that they would have a solution for me by the end of the day. I provided them an email address and alternate contact number again and 24 hours later I still have not heard back from them.

Christina,

Yes I actually heard back from Verizon Support this morning. They said

everything was working on their end and that there was nothing else that

they could do for me at the moment. They suggested I take it into the store

and have them check the phone out. I stopped by a Verizon Wireless store

(not an authorized retailer) and they replaced the SIM card but I still

can't make phone calls while still having a solid data connection. I talked

to two different people there and they both agreed that I should get a new

phone.

Do you have any other suggestions for me at this time? Or should I start

looking into a 3rd party for repair/replacement.

Thank you,

Jeremy

Any fix? I have been having the exact same issue and all the verizon rep could do was change the sim card as well.

PopNetInfo

No unfortunately not. All I can surmise is that the CDMA radio died but the

LTE radio is still going strong. Some local electronics chop shops "think"

they can fix it for $50-70 but I'd rather not risk it and break the LTE

radio as well.

I've basically resigned to using GrooveIP to do VOIP and wait/hope for the

Nexus 5 on Verizon. If you come up with a solution please let me know.

Dwest94

I'm having the same exact issue as well, I spoke with tier 1 and 2 tech support with no resolve. They were telling me that it's my phone and started selling me on other products... There has got to be a fix

PopNetInfo

Sorry I don't have any solutions for you. As far as I can tell the CDMA

radios on these devices are "expiring". I've tried everything I can think

of, within reason. I called Verizon and even got a ticket opened with a

level 3 Engineer, no luck. I took it to a store and they wouldn't even try

to repair it they suggested I purchase a new phone.

I even took it apart myself using this

http://www.ifixit.com/Teardown/SamsungGalaxyNexus+Teardown/7182/1 break

down and inspected the parts. Nothing seemed to be damaged or corroded. I

have not tried replacing any parts or doing a "reflow" on it yet as I don't

want to loose the LTE radio as well.

If you make any progress please let us know!

PopNetInfo

>>comments deleted<< and the same exact issue is happening which leads me to believe it is most likely a hardware issue.

I just arrived in NYC and turned my phone on and sure enough I can

send/receive phone cals and text messages.

We will see what happens when I get back to Florida

Dwest94, this is an odd coincidence! Let's investigate this matter. Have you downloaded a few 3rd party applications to your device? Some 3rd party applications can affect the performance of your device. I recommend that you uninstall a few applications, briefly remove the sim card, and power your device off/on to soft reset it. Keep us posted.

Hi DaveinDiego. Changing out the SIM card is definitely a good step to take in getting your services back. Thanks for trying! Do you seem to only have the issue with service when in a particular zipcode? Did the new SIM have any improvement in your service? Has your phone been damaged or exposed to moisture? Is the phone less than a year old or do you have an extended warranty or insurance? Please share a few more details about your personal experience and we'll see what we need to do to get your phone working again.

Thank you

I'm having this same problem. First, it happened when I visited West Virginia, but when I came back to Virginia my phone worked fine. Every time I went to West Virginia, this happened, but I didn't deal with it because I was only out there for a day. Now the phone/text won't work in my area in Virginia. Did your phone end up staying "fixed" when you went to Florida?

PopNetInfo

Sadly no. As soon as I got back to Florida it had the same issues.

I called Verizon while in New York and they said they would do a follow up

call the next day when I would be back in Florida. They did not follow up

and I ended up calling them the following weekend. I explained what

happened and they said that they would look into it. They said they had

engineers check the area for signal issues and I had to explain that no

other Verizon phone around me was having this issue. They then had a Level

3 tech support follow up with me and we did all the same troubleshooting

from the 1st and 2nd tech support calls, same result. They stated it must

be the phone and suggested I call Samsung as they are the manufacturer and

are responsible for the hardware of the device. The Samsung support line

they provided was 888-987-4357, but I have not called them.

When troubleshooting the last time the tech on the phone mentioned that she

was receiving a ping signal from my phone that was indicating that it was

trying to connect through the Sprint cellular network. Whether that was for

the LTE or CDMA/GSM bands I'm not sure. I've not had any issues with 4G

Data and the speeds seem to be the higher end Verizon ones that I am used

to and to the best of my knowledge our version of the phone does not have a

GSM radio. When she had me boot into recovery and clear my Dalvik Cache

then boot into safemode the phone stopped sending any signal of any kind

(including data) and that was when she decided it was time for a new phone.

I left it in safe mode and a short while after the call ended my 4G data

connection returned but no call/text still.

I'm not a cellular networking engineer but this is what I know:

This issue started randomly. I did not damage the phone it did not over

heat. I was at dinner and it was in my pocket.

I have never had issues with 4G LTE network only the CDMA network.

My phone says "No Mobile Network Available" indicating that it does not see

a CDMA network, or is not allowed to connect to it.

When in "Roaming" mode I was able to make phone calls and send text.

I believe Sprint has some sort of CDMA network, which would make sense with

what the 3rd support call stated, and my phone can connect to their network.

If Verizon edits the following statement please contact me directly for the

info.

After all this and a month+ of not having a phone I tried reflashing the

radios with ADB (Android Debug Bridge) and the LTE radio took about 3

seconds then when it moved down to the CMDA radio it took 94 seconds to

flash but did say successful.

Here is the log:

sending 'radio' (10496 KB)...

OKAY

writing 'radio'...

OKAY

finished. total time: 3.692s

sending 'radio-cdma' (3724 KB)...

OKAY

writing 'radio-cdma'...

OKAY

finished. total time: 232.964s

As you can see it's taking 30 times longer to write 1/3 of the data, which

just doesn't add up. As I said before I am not a cellular engineer so take

what I say with a grain of salt.

Conclusion, there are likely 2 scenarios happening.

1. The CDMA radio has issues to the point Verizon's network does/can/will

not recognize my device but other cellular providers will.

2. My device has been black listed (probably for still having :O unlimited

data) or the ESN/MEID is reported as stolen. Both of which I'm not sure how

to find out.

I hope this helps everyone else out here. Let me know if you have more info.

Apparently the log had code that Verizon's forums recognize as links to posts. Here is a slightly edited version.

I lost my GN and got a replacement from Asurion ($99 deductable, Ouch!). I've had the exact same problem with the replacement phone from day 1:

Intermittently, the phone will lose it's connection to the Verizon network. This affects both 3g and 4g, voice and data. WiFi is unaffected. I've even had the voice cut out in the middle of a call, causing a spontaneous reboot. The outage can *sometimes* but not always, be cleared by either turning airplane mode on/off or rebooting the phone. The outage eventually clears itself after minutes/hours, but always comes back.

I've been online a bunch with Asurion tech support and we've done 3 factory resets. The last time, I told the phone *not* to restore my apps and data from backup. Problem still happens.

Asurion is supposed to deliver replacement phone x2 today. I'll update this post when I get it.

Cheers

I'm having the same issue with my Nexus here in Florida. Spoke with technical support via live chat and we came to the conclusion to get a new SIM card, which didn't work. About to get back on with technical support again. I feel it's most likely the radio. Only 2 months until my contract ends!

I hope you meant a new SIM card, because there isn't a SD card slot in the Galaxy Nexus phone.

Ha, I did, thanks!

@MattAPaul,

I definitely don't want to see you go! Let's get your phone back up and running! Being able to call and text is definitely a must!

Is this happening only in a certain area? What's the zip code where you are experiencing these challenges? Does this happen only when indoors, or outdoors as well? Have you contacted our technical support since you posted here? Please keep me posted if you need further assistance.

I have been diligently following this thread since it was originally posted.

https://community.Verizonwireless.com/message/1016588#806311

I have been experiencing the EXACT same issues over the EXACT same time frames and have tried all the EXACT same generic "remedies" Verizon has proposed; none of which have worked.

This is not an issue with the SIM cards, the cell phone/cell phone antenna/cell phone radio/etc. It has nothing to do with the phone's ROM/patches/or installed software. The phone does not need to be factory reset, replaced, or repaired. We paying Verizon customers most definitely do not need to PAY to be "UPGRADED" into the newly unveiled "EDGE" program; which is the most insulting and egregious recommendation I personally have been given by Verizon representatives when it comes to this issue.

This is, without a doubt, judging from my ongoing experience and the ongoing experience of many others on this and various online discussion threads, an issue with Verizon's network when it comes to allowing the galaxy nexus to work on their network.

I am an attorney in Philadelphia who travels the country for my job. I expect and need my cell phone voice and text messaging services to work. I, and the others on this discussion thread, have paid Verizon for these phones, for cell service, and technical support. Verizon is clearly in breach of the phone service contract.

We are NOT being helped and we are stuck with non-working devices that we are STILL paying for each month.

Verizon's customer technical support tracking database must be rife with reports of this very issue.

Like the others on this discussion thread, my attempts to get this resolved by visiting various Verizon stores and via the Verizon phone help line have failed.

Has ANYONE at Verizon investigated "PopNetInfo's" suggestions in the aforementioned thread that possibly:

1. The CDMA radio has issues to the point Verizon's network does/can/will not recognize my device but other cellular providers will.

2. My device has been black listed or the ESN/MEID is reported as stolen.

Has ANYONE at Verizon done ANYTHING regarding this issue aside from offering affected clients basic, tier 1/2 tech support troubleshooting suggestions?

ATTENTION VERIZON SUPPORT REPS READING THIS THREAD: I, and all customers on this discussion thread, need some of Verizon's senior-level management and technicians to get involved in this issue on behalf of all Verizon customers experiencing this issue immediately. At this point, we fully expect these senior-level Verizon personnel to start speaking and working with us directly and individually on this issue within one week's time or less. We expect the issue to be seriously investigated and remedied as quickly as possible. We also expect proper and full compensation for the months of service we have been paying for even though service is very clearly not being delivered. I personally have been using verzion, and ONLY Verizon, as my cell provider for nearly 20 YEARS! I, for one, will be canceling my service in one month and switching to another provider if I do not feel Verizon wishes to work with us immediately on this long-standing issue. I suggest all others on this thread do the same.

Verizon_Support

Thanks for following this thread and for attempting all the steps we provided for resolving this issue tmfESQ. I know this is frustrating for customers but we stand behind the issues you're having and do all we can to help get them fixed. First, all customers are not experiencing this issue with this particular phone. All issues are reviewed on an individual basis according to your device, area, software and other steps we have attempted. With this issue, we trouble-shoot the phone by providing steps that usually resolve this type of issue (safe mode, hard reset, memory and damage). Then we address the software, making sure its updated and no unauthorized software is on the phone. We then address the area, making sure our engineers have not reported any problems in the area. Lastly we file a trouble-ticket to have our technicians and engineers look further into the area. The status we receive back will let us know the next step to take for your individual account. That may include a replacement phone, which is a certified like new device of the same model if your still under the 1year manufactures warranty and have no damage to your device, a network extender depending on if issues is more inside than outside, and lastly simply letting you know the area is challenged and the phone is not the issue. For any customer having an issues with service, we recommend contacting us to get the ball rolling with the above steps.

We want this issue resolved for each and every customer and if we have to discuss a different step for each customer we are willing to do this because we care about your service.

If you have had a trouble-ticekt filed already tmfESQ please provide that number and I would be happy to provide you with the status. If you don't have a ticket processed yet, please contact us here, at the store or by phone.

I am having the exact same problem. I have a Galaxy Nexus. Just last week I traveled from Portland, OR to San Francisco, CA. My phone stopped receiving a signal and I could not call or text. I noticed other people with verizon devices had no problem. I was able to get data with 4G but could not call or text. When I finally got through, the call was choppy and then cut off. When I got back to home to Portland, I had trouble getting signal and connectivity at home and at my office, where I had no problems before.

I took it into the verizon store and they replace the simm card, but nothing changed. I am still having trouble making calls and texting.

What's going on?????

Ann154

I have been using my Galaxy Nexus as phone again for the last week and thankfully the phone calls haven't been choppy during that time. In the past months ago, I did have some issues where it was hard to hear the caller on this particular phone.

Verizon_Support

Hey there stevenpdx,

I'm sorry for the reception issues that you are having with your Galaxy Nexus. Let's keep you connected. What zip code do you have issues in specifically? Do the issues primarily occur indoors or outdoors as well? Does service improve outside of the zip you are having issues in?

Now that you are back in your home area I would recommend powering the device off and removing and reinserting the sim card. This will refresh your connection to the network. Here is how to properly handle the sim card,http://vz.to/19jJtZW. Keep us updated with results.

I'd appreciate it if you could give me a direct number to an upper level manager or senior technician that can solve my issues. As I've said, all the basic attempts to fix this have failed, and I don't have time to be wasting by calling into the regular support line or going back to the local store when they can't help me. Not to mention I have a very busy work schedule and would like to be able to deal with this when I have some free time rather than waiting on hold on the phone or standing around in the store waiting to be helped. I do not have a current trouble-ticket that I know of, let me know if you need any other information from me, thanks!

Verizon_Support

tmfESQ,

As well as customer service, we're technicians here and are more than happy to work on your issues. Please accept my follow request, follow back, and direct message your name, mobile number, and billing system password (or last four of your social if a password isn't present) so we can research further into this situation and advise.

HelloThereKitty

I also have the same problem, when I first got it, it was working fine, 1-2 bars in my house ( I live in a three-story apartment building on the first floor, so I don't mind some choppiness), I had 1-4 bars while I was walking home to school and back. A few weeks ago, a problem appeared. My Galaxy Nexus basically decided that it was 5 bars or nothing. I can only get signals where it's obvious there's a Verizon tower nearby. Over the past few weeks, my phone has either shown 5 bars, or "Searching for Signal". My family has 4 lines, an HTC Droid, LG Lucid, and a Samsung Galaxy S3 and they all work just fine with a signal of 1-3 bars. I'm not getting anything, although I am a student, I manage all the financial, medical, and billing sides of the family. I need to go about a mile away from my house to actually get a signal, and check my voicemail. I don't want to travel a mile (no car) just to check whether it's just my mother that never pressed "END" while she was calling me, or a voice mail from my doctor about medical problems!

Verizon_Support

Hi HelloThereKitty,

I am sorry to hear you are having service issues. What's you zip code? When having issues on your devices, have you tried doing a soft reset to refresh your signals? Give that a try and keep me posted.

Thanks,

I'm started having this same problem about a couple months ago and couldn't figure out what the problem was either. I would have 4 bars signal but get the same no network available message even though I'm sitting beside my network extender. I have had to power off/on my phone to get it to work again. After I power it off/on it works for a while then have same issues again. I know it's the phone because my son's iPhone and my wife's Razr works fine sitting right beside me. This is ridiculous that we have a phone that can't get the services we're paying for.

Sportager

I live in Portland, OR, own a Galaxy Nexus, on s shared family plan, with unlimited data on the device that is experiencing the problem. On Thursday, January 16th, the triangle in the upper right portion of the Nexus screen that indicates the signal strength by showing number of bars went entirely blank while I was in my usual downtown location. I figured Verizon was experiencing a cell tower disruption in the area. After commuting home, the triangle remained blank; devoid of signal strength bars.

I am able to get on the internet; I can't make or receive calls or text messages.

My calls to tech support started Friday morning, 1/17/14. I went through the low level troubleshooting with the person on the phone and they had to bring on the next level of support. Since then I have been to a Verizon store location and have swapped sim cards and gone through troubleshooting again in the store, with a technician on the phone.

After mentioning that I now have two non-functioning Galaxy Nexus phones for which I am paying for service (the other one suffered a small amount of water damage that rendered it disabled), they did offer to replace my phone. They asked me if it was undamaged and I honestly answered that it had a small crack in the screen. All offers for a new phone were off the table. I had wasted my second hour of life on the phone with their tech support and handed the phone back to the in-store gentleman. He ended the call and we discussed options. I mentioned that other cell phone carriers will pay termination fees for you to move over and this seemed like my best option.

He suggested I read the fine print in those other carrier's contracts then started pushing their "EDGE" program (which seems designed to compete with other carriers).

My best option at this point is to either use a "shoebox phone" as suggested by the phone support tech, or to move to another carrier. Since I only have a Droid I (and it is of marginal health) smartphone, I must either revert to a dumb phone or try the Droid I.

I think I will be forced to move carriers after 5 years of service by Verizon. Do I really need these phones and the monthly cost of ~$130 to keep them with Verizon? I can use my employer paid blackberry (Verizon) instead.

Do I pay early termination fees and get out of the remaining 4 months of contract ($300 for 2 phones) or pay ultimately $520 to pay for those four extra months? The answer is obvious to me.

There is definitely a problem surfacing with these phones on Verizon. I like the legal angle as this could be considered fraud; "wrongful or criminal deception intended to result in financial or personal gain".

Sportager

Verizon_Support

We don't want you feeling out of options, Sportager. It's true that any damage to the phone, even a small crack, does void out the manufacturer's warranty so a free warranty replacement isn't an option. But there's other options beside leaving or paying for phones you can't use. If the Edge Program (www.vzw.com/edge) isn't the best path for you, we also have a Certified PreOwned (CPO) Program with Smartphones as low as $199.99 or basic phones as low as $89.99 without a new contract or change to your upgrade eligiblity. The CPO phones come with a 1 year warranty and the ability to add insurance too. You also have the option to just activate a phone from a friend or family member http://vz.to/186e0Pr or even purchase from a 3rd party.

Thank you
