Are you rooted?
P.S. Your wife works in a low reception area?

Looks like this is becoming an issue, there's two existing threads on it so far:

I'm hoping there's a fix soon because I love the phone and don't want to return it.
Edit: Just happened to me again sitting here at my desk with good signal.

Nope not rooted.

I know the Nexus had a crappy radio but I never lost connection with it, especially at my home where I lost data/cellular connection twice so far

Unfortunately I cannot say that I have experienced this, while I am at work I have my Wi-Fi on 100%, and whenever I step outside of the office to use the bathroom, or to go to the vending machine (Wi-Fi signal still barely reaches), There have been several times that it would drop the connection because the signal was too weak. However as soon as I got back within proper range It would reconnect immediately with no problems.

well I called sprint last night and the reprovisioned everything. They said this is the first that they have heard of it and are sending the info to sprint and samsung. I will report back later if this fixes her problem. I doubt it will though, because other post have shown that this is just like doing a profile and prl update.

I just tested my WiFi again at work. I am standing next to the WiFi Router, and cannot get a connection unless I reset the phone. I am frustrated. I cannot reset my phone everyday when I come to work just to get a signal.
I just jumped ship from AT&T's iPhone to this, and need to decide where to go next. Verizon Bionic?

I had same problem happen last night. Showed the international no symbol and didn't get a signal until I rebooted.

Just spoke to Sprint rep about service outage.

So for the past two days I was not able to send or receive phone calls or text on my phone in the Brooklyn NY area. I thought maybe it was something to do with the rom I flashed or that sprint was just having outages. The funny thing is 3 and 4G worked perfectly fine. So this morning tried to call my wife on the using the cell phone and she couldnt receive calls.
So I called sprint this afternoon and they said that there was a problem with a few towers in Brooklyn where the 3g signal was interfering with the singel cell calling.
Supposedly this is suppose to be fixed by 12/21/2011 20:00 est.
Edit:
The rep wanted to do some basic trouble shooting on the phone via the network, so I am wondering would my phone being rooted and romed cause a problem with said troubleshooting.
Edit 2:
I posted this here because at first I thought that it was caused by the rom I recently flashed and I am just giving a heads up to people who may think the same.

I don't think so, either way it is easy to go back to root.

I called in for Jersey and they said there is an outage. My texts usually fail to send but they say it'll be resolved within the week...

I've been having issues in my part of Brooklyn for months now. Same thing, 3G works fine but texts and calls fail.

Chiming in well i live in brooklyn and i nor my wife have not had any call issues in my area at all.

We are both spilling having the issue. No voice or text via sprint or Google voice. I was told the tower issue in new york was suppose to be fixed last night. But we are still having the problem.
It's funny because the phone works everywhere else except in front or around or in our house. If I go five blocks away from my house the phone works fine.

I called sprint and told them i had no service and no data in most of my city.. " what is it, that youre using?" i said "a cell phone..." he said exactly, its used to make calls not to surf the internet
whats funnier yet is that he was about 25 years old..

I'm in a different state and its happening to this area too. In store rep said they are aware of it and they are working on the problem. She said things should be fixed tomorrow friday, at least for my area. Some texts are falling into the black hole and some have come through hours later. Internet works. Texts ride on the phone line and not the data line. Even on wifi texts would fail. Phone calls worked sometimes. Some towers were not affected and some are. The one for my house is intermittent.

If your connected to wifi it only cover data and wont actually place a voice call through wifi right? Just data like picz and internet correct?

I believe so. I think email and internet works on wifi but not calls or text. I thought google voice ran on the internet side but I did see some failures with that too so I don't know,

I don't use a cell phone.
I use a Data Pad or PDA that happens to also have a cellular radio and it can if I want make calls but that is a secondary function.
and thats what I would have told him.
I would have said. you see the unlimited data? see the 500 minutes. Take a guess which I use more hehe

It's strange there seems to be a 5 block radius in my neighborhood where you can make or get calls or text with sprint since Tuesday. The funny thing is it is with all sprint phones and they say they are not aware of an issue. Their are 4 sprint phones in the 3 family building that live in and would have to be at least a 100 or more in the neighborhood. It's seems to only affect he phone during the day because late at night and early in the morning the phones are fine.

Bay Ridge resident here. For about a year now, data fluctuates anywhere between 100 kbps to 1.5 Mbps, but usually in the 200 kbps area. Been complaining for what feels like forever (issue has been there since last January). I've gotten a million and one excuses, taken it all the way up to the office of Dan Hesse (I **** you not). They credited me one month's bill and that was about it. This was a long time ago. I love the fact that Sprint has unlimited data and is cheap, but that's about it. Service itself sucks.

Just got my airave.. and i figured out why they have no problem sending it out for free... it turns that 5 mile radius around your house into a sprint tower for anyone to use... using the internet YOU pay for...and my calls are still broken up when i make them...the sprint rep couldn't hear me when i was talking to her on it... lol.oh well i guess i changed my prl to a really good Verizon one. I'm happy now

You pay for your high speed don't you? Or is that given to you for free? And the average person wouldnt know that u can't do that. To each their own. If u like it then great! I think its a sham. I shouldn't need an extra tower in my apartment to get my cell phone to work.. that is on sprint.. oh and before anything is said about where i live, i am located in the top 5 most populated cities in Michigan.

[Q] Horrible signal. My problem or Sprints?

So today I have had issues with connecting to Sprint's network. In a city near mine, they are upgrading to 4G. My phone has been going from full signal to zero signal within seconds. It is killing my battery life. I am running CM10.1 with the current nightly. I restored a previous version of CM to see if it was an issue with the ROM and I was getting the same results. Do I need to flash the radios or leave it be? Could it be because of Network Vision? Is there a way to back up my current radios in case something goes haywire?

Its most likely a carrier issue....make sure you have the most current radios installed which are FD02 if i remember correctly....other than that its a very rare occurance that software would affect your signal...probably due to the work that they are doing in the area....turn off LTE and see if the 3G signal does the same thing...good luck let us know what happens

Its sprints terrible network.

I've turned off 4g, reconnected with airplane mode, restarted my phone, fixed permissions. 3G is the same. I hardly have any service. The thing is, the past couple weeks the service here has been awesome. Then yesterday, this.

Well, I have confirmed it to be on Sprint's end. All it took was a quick drive around town to pick up a different tower. My buddy has a signal booster in his apartment and I was picking up full bars there. Here's hoping LTE is close!

4g no bars at home

Alright well my issue is pretty simple basically at my home I was able to get a cell phone signal last summer when I bought my GS3 it was only 3g but it got the job done. Now it seems that AT&T has expanded LTE to the area but just barley. My phone depending on whether im lucky or not will have 0 bars connection but day it's on 4g LTE yet if I try to text or make a phone call nothing and if a person tries to call me I never get any sort of notification most people think I'm just ignoring their calls because they get rung to voice mail as if it's a normal call. This wouldn't be so bad if dialing data worked but the phone seems to still have no signal when I do that. The APN trick has also failed me.
So my question is, is there somebody else out there that's found a solution? I have searched the forum but to no avail. Maybe I'm just searching the wrong keywords? Any help or suggestions would be appreciated.

so you've changed nothing on your phone since last summer? just the signal strength began to diminish?

I have gotten all of the ota updates. Was running a custom rom for a while but have been sitting in Stock for about a month now.

Toggle airplane mode and see if signals changes. Also flash a different modem. Possible it at&t as mine changes all the time. I'm right on the edge of lte andbin and out all the time.

Airplane mode definitely did make the signal go up a bit. I am going to try to run different modems the next few days (one each day) and record the results.

Anyone notice their service getting worse?

At first I thought it might have been my rom, but it seems it's happening with my GF's note 2 also.
Coverage we used to receive in some areas is almost completely gone. It will show signal and the 4g symbol but basically have NO internet service whatsoever.
On a better note, we've been receiving coverage in some areas we don't usually have it.
I'm hoping this is just a temporary thing due to the attempts to upgrade towers for LTE.
I don't know if it's because of the UVBMB4 update, but t-mobile service has been pretty crappy lately. Period.
We're in the San Gabriel Valley area.
Link for older UVALL4 modem below, people seem to experience better service
http://forum.xda-developers.com/show...php?p=36786363

I believe my service has suffered as well. Before the last update that enabled our Lte radios, I had great speeds, now it's slowed Way down. I'm in San Diego CA. Hope that it's just as the Op said, LTE towers being updated and what not.

Definitely have noticed a deterioration of service over the past month here in NYC.

Its because for some reason that new LTE APN is slow on HSPA+.. unless you have LTE in your area switch to the EPC APN. You can find the settings online. Its litter ally consistently a difference of 6+ mbps I have extensively speed tested lol..... click thanks if this helped

I also had problems even with old apn.
Flashed previous radio and service is top notch again.
Sent from my SGH-T889 using xda premium

Same here, I thought it was rom related.

YES! My service has sucked royally for the past month or so. Data latency/hangups/slowness, and the signal will just completely go away sometimes. I noticed that it started as soon as I flashed the most recent radio too, I'm about to go back to the old one.

Count me in, even my regular phone reception went from 4 bars no 1 or 0!

Can anyone point to towards old radio to flash? I go from no signal downstairs to full bars upstairs...theres an obv issue with new radio.

Yup I've noticed this beginning this week I've made zero changes to the phone. I used to get full bars at work and this week it bounces between full and 1 bar regularly. Theure messing with towers for sure

I'm also experiencing significant decrease on data speed. Has your data speed improve after flashing with older radio and APN setting?

I was getting about 9/0.6 and with flashing back Im getting... 14/2 Though Ive been on HSDPA 15 & 21. Though Im not getting 4G as much, but it was sporadic anyways and I lost signal...and now I am not. So, Im happy now even though I am on 3G. However... in my corner big red has same problems as they wanted to not have tons of towers in this corner and theres only a ATT Tower....for a decent distance. basically reception fringe. though I am a new subscriber so i haven't experienced normal TMO, I literally got my device yesterday around 6pmish but it def wasn't normal and flashing previous radio did fix it like it solved everyone elses issue

my problems started last friday. i have limited to no service at all; no data, no voice, even no signal at times (circle with line through it, not just no bars). when i do get a signal, the phone refuses to register on the network. when im at home, i have intermittent service. i miss calls, texts wont send, if i do get a working call, it drops after a bit. there are times when it works fine, even on LTE but it never last long. went to the tmo store last night and they gave me a new sim which didnt do squat. already done the factory reset option (twice). phone has never been rooted, all stock. im in the KC metro so not like in the middle of nowhere. they said my next step is a warranty replacement phone if the sim didnt help. not sure if my problem is at all related to everyone elses in this thread, but yeah, service has sucked.

One of the issues, especially if you switch from 4g to edge to gprs a lot, is a setting in the new modem.
It's something called acquisition order. It has 3 settings:automatic, gsm_umts, umts_gsm. In short it tells the phone what kind of network to prefer. It will search for and use that type of network first.
Prior to the latest update it was set to auto. Now it is set to prefer umts. For some reason this has caused an issue I've come to call phantom 4g. Where it'll say 4g with no bars and no data service.
That is my guess. I'll look into it further.

Thanks guys for the heads up on switching to an older radio, I dont have LTE in Miami yet and was having slow internet for the last 3 weeks, I just switched and wow! What a difference. I'm also using the Epic APN.

I also noticed that speeds were degraded after the update. However, there is a simply fix to make your web a tad bit faster....
Go into your network settings, and switch your mobile network from LTE/4g/3g/2g to just 4G/3g/2g
your device will stop looking for an LTE connection and will just utilize HSPA+
Made a world of a difference on my own device. Connecting to the play store, opening web pages, everything was right back to where it was before the update.
Obviously if you live in an LTE area, there is no need to do this...

So I'm gonna be a noob here for a sec. When people say they are flashing the previous radio (I'm referencing the link that was posted) are people just flashing the modem from the section under the most recent? (the one with the January date on it). Just thought I would ask. Better safe than sorry. Thanks!

Yup, radio is synonymous with modem in this case. UVALL4 is the previous version.
