4g/3g data connection

It seems whenever I don't have a 4g data connection, I'm not getting any data connection. Anyone else have this problem? When I'm in builldings I never get a data connection. Even when I'm outside I rarely get data connection unless it's a 4g spot. I know someone with a GN and side by side, he gets a connection at work while I have gray bars. Is this prevelant among most of you all? I'm on Verizon if that makes a difference.

Yes, I have this issue as well when I am at work but only when I have wifi turned on. With wifi on I get no 4g connection inside the building and the phone won't drop down to 3g, just gives me gray bars and no data. Manually switching from LTE/CDMA to CDMA restores my 3g data connection. Turning wifi off enables the LTE data connection. I assume it's trying to use the building's wifi network that I am not authenticated to for some reason. It's quite annoying and seems to be draining my battery.

My 4g reception sucks. I am rather disappointed. I canceled my ATT account and paid the ETF to switch to verizon for the GN. I am in plano tx which is in the Verizon LTE area and i dont get any signal except in a few spots on the highway. I work in Richardson, which is also in the LTE area, and i dont even have 3g in the building. I dont have any signal when i go deeper into the building away from the windows. I am running stock 4.0.2. I hope this gets better. I am already regretting dropping ATT.

Strange. I have excellent 3G and 4G signal in buildings, coming from Sprint I had non-existent data everywhere, especially indoors.

Just as an fyi. I went to Verizon to try to get a new phone. They told me my sim card was bad. I got the phone on the first day and they said they had issues with the first sim cards with the nexus. My wifes has the same problem.
New sim card, NO MORE connection issues. Yeah! Anyone else who has this issue might try this. I am now getting 3g and even 4g connections inside now.

ill go to the verizon store after work and switch sims. Just got it on 1/1. Ill go to a different verizon store to make sure its not a bad batch lol.

Wasnt the SIM card. Still getting crappy signal strength. I am going today and replacing the phone. If that doesnt work, i am going back to ATT skyrocket...

In my office I get very weak to no 4G signal, so that the phone is constantly switching from weak 4G down to 3G and causing connection disruptions. I usually just disable LTE and use CDMA only mode to fix this. I have heard that a LTE signal should penetrate inside of buildings better, but apparently my workplace is almost impenetrable. We have a Verizon 3G repeater in the office or I would get no usable signal at all.
Spencer, what kind of speeds are you getting with LTE in the Columbia area? It seems like I got better speeds when I had my Rezound than I'm getting with my Galaxy Nexus.

I've had the exact opposite experience in Dallas. I switched from AT&T a year ago. I couldn't even make calls in my house. (I live in Lakewood) I had to go upstairs or outside. As far as data goes even on just 3G the Verizon speeds are much faster. I've done quite a few AT&T vs Verizon 3G side by side tests and Verzion has won every time. 4G is just a bonus for me. When I get a 4G signal there is no comparison. My coworker and I did a speed test on Tuesday at DFW. His iPhone 4s on AT&T vs my Gnex. I was getting 10-15 mbits down and he was getting like 2-3

3G Data
I am having the same exact problem. I thought it was related to airplane mode, I have it turning on at midnight and off at 6am. In the morning, if there is no Wifi and the phone is in 3G, I can't get data. Restarting gets data back, but I'm looking for a more elegant solution than that.

I'm having HUGE data issues, see:

just a quick question. are you guys running custom ROMs/kernels? if so, please add that in your post.

[Q]How's T-Mobile Service & their Wifi-Calling?

Hi Guys, I posted similar post on N7100 asking about T-Mobile Service but since this is actual T-Mobile forum, I thought I could get better feedbacks.
I'm currently with AT&T and service isn't that bad other than extremely expensive plans and slow data speed on my Galaxy i9300. Most of the time on H+ I barely get 1 mbps so I'm thinking of jumping on carrier branded Note 2 with LTE/4G.
I would like to know how are your service with T-Mobile? I know it really depends on locations but generally is it good or bad? Also how is their Wifi-Calling? I absolutely need this since I won't be getting service at home. (AT&T is same, so I have MicroCell setup) Wifi-Calling seems lot more convenient since Wifi is every where now days. I know I could go to T-Mobile store and do 14 days trial but I rather skip that hassle and ask this awesome community
Hopefully I didn't take too much of your time! Thank you~

That is up to your coverage map but I would say that if your having issues with AT&T's hspa+ then T-mobile might not be a great choice but it all depends where you travel... The wifi-calling is an added bonus that I like to have! Definitely look up your address and see what "color" you live in and talk in and that will tell ya... I get fine service even when I only have one bar of signal strength but I'm sure that it varies by location and phone. Where I live AT&T has a much faster hspa+ network than T-mobile does but this is kind of a "dummy" line for me to play with... LOL I just have the $30 Walmart prepaid plan..

Both carrier supposedly have good coverages where I live but I don't get any reception inside of home, which is pretty lame and drives me nuts!
I keep hearing wifi-calling being buggy on note 2? How's your experience with that?

I'm getting 15mb/s where i live (NYC and Long Island). Better than At&t and Verizon overall, especially for the price and free mobile hotspot. I have better service then other providers here too. WiFi Calling is also great

What...!? O_O someone stole your phone? Omfg I'm so sorry to hear that man... I hope you had insurance on it, or hopefully gps tracking will help find your phone

wifi calling has worked great on my Note2 and was part of the reason I switched to T-Mobile... Verizon has 4G LTE where I am at currently; however, if they are having issues with their 4G network it is a huge PITA.... sending texts/calling over wifi is a huge bonus and definitely comes in handy

Wifi Calling is awesome if you can get a good wifi signal. At my home I get the speeds in my signature (11Mb/s down 4Mb/s up) and live in a full 4G coverage area. Where I used to live I barely got 2 bars of edge, which in that case I would use wifi calling exclusively. You do need a pretty strong signal with wifi calling (at least 2 bars) and a decent upload rate. Other that that it's great. I'd also recommend setting the preferred call method to cell (above wifi). That way you'll use cell always unless you have no coverage, then wifi calling will kick in, and it's very nice to see wifi calling when no one else can get a signal! Like others have said, check the coverage map! Where I live in Michigan AT&T stinks, my parents have them and can't get a signal anywhere. They are very jealous at my house when they have no signal and I have full 4G goodness! :good:

[Q] LTE reverting back to 4G while on a call?

I finally got 4G LTE on my block. I am getting great speeds. The only problem is , when I am in a call it reverts back to 4G. Is anyone else experiencing this problem? I am rooted, running Darthstalker S4 V2. I called T Mobile today to put in a ticket. They said it's the first time they hear of this, and it should not be happening. Maybe between us all here in the community we can pinpoint the problem. Curious to hear from you all.

I am pretty sure this is normal behavior. I am not sure why, but that is what my phone has done since day one (the indicator anyway, I haven't tested actual speeds). The HD calling works, so I assume it's still LTE.

I beleive LTE is only for data. Like on the S3 it would show H while on data then 3G when not using data.

I have tested the speed while in call, and they do drop to 4G. The TMo rep told me it wasn't supposed to so that. How can you tell the HD calling is working?

Speeds were good enough for me while on a call I haven't really noticed if there was a decrease. As far as the HD calling is concerned, there is no indicator, but the sound quality is vastly superior (the first time you experience it, you will understand). Both phones need to have hd voice capability and be in LTE coverage. My understanding was that it requires either bandwidth or something else the LTE towers provide. I don't even think it works with wifi calling...

I guess I have a reason to make my wife get a new phone now!! http://forum.xda-developers.com/images/smilies/fingers-crossed.gif
As far as data speeds while on a call they do greatly suffer. Here is a speed test while on a call. If both phones have to be on LTE to experience HD calling doesn't that mean we have to stay on LTE while in a call? As you can see in the screen shot, signal reverts back to 4G. Now I'm back to square one.

Here is your answer: "4G LTE does not carry voice services, so calls will fall back to our HSPA+ network until voice over LTE (VoLTE) software is ready." (Click here for their support page.)
There is nothing wrong with your phone, this is just the way it works currently. I am not sure about the HD voice since that theoretically requires LTE...

I think this pretty much sums it up.
While the industry has seemingly standardized on VoLTE for the future, the demand for voice calls today has led LTE carriers to introduce CSFB as a stopgap measure. When placing or receiving a voice call, LTE handsets will fall back to old 2G or 3G networks for the duration of the call.

how's T-mobile connection in Chicago Area?

Thinking about switching to T-mobile in the SW Suburbs of Chicago; I'm on wifi most of the time, so data speed isnt important to me, but, we MUST have good phone call quality in our house.
Is this an issue for anyone in chicago land, or, if we get a phone that is "wifi capable", and we have a fast,strong, wifi network in our house, does this become a non issue?
We had ATT, which was no problem in the house, and recently switched to Sprint, with the hopes of a stong "Spark Network" here; well, one of our phones in Spark compatible, and works fine, but the other 2 phones are HTC One's, not spark "compatible", and have poor phone call quality and reception in the house. We are waiting on an AirRave front Sprint, but, if that doesnt work, we're ready to go to T-Mobile..
Sorry for this weird question here, but, I trust my buds on XDA to give a real report on stuff like this, NOT the people from T-Mobile
Thanks! :good:

What town are you in? I have excellent call quality in Posen/Oak Forest/Orland Park/Crestwood area. And LTE when available is super solid. Seen a best of 39MBPS in Ookla App. I also had ATT until recently. I really can say, that I'm happy I made the switch. I also know many ppl who are on sprint and constantly suffer from dropped calls and data connection issues, my house is a sprint problem area as well btw.

I'm next to burr ridge/willowbrook, in an area called Timberlake.
My Sprint Airrave is supposed to be here tomorrow, and if it doesnt fix the problem, its tmobile and wifi calling for us!
We had Sprint for many years here, using an AirRave, and it was fine, but, a couple of years ago, their network went completely to hell, so we switched to ATT; after awhile, they were just bad to deal with, and Sprint announced this new Spark Network, in Chicago, so we thought, why not, its cheaper than ATT, and with this new network, it will be fine.
Problem is, if you dont have one of their 3 tri band phones,(which I have, but my wife/son do NOT), then making calls in some areas is horrible.
My wife works from home alot, and making calls for her is bad news, especially conference calls on Global Crossing, so if the Airrave, which uses wifi/internet to make calls, doesnt work, its t-mobile for us.
I understand that using wifi to make calls from you house with Tmobile is fantastic, and I have a great, Asus ac1900 wifi router in the house, which gives super fast and strong wifi, so I am sure that t-mobile wifi calls would be clear as a bell here!
thanks for the info :good:

I live in Joliet, and I get great service. Always connected to LTE, and never lose signal. I get spotty service in my apartment, but that may be because I'm on the bottom floor of a 3 story building. It doesn't bother me though because wifi calling works like a charm!

Poor signal ?

Hey guys,
I have had a couple people complain that when I was talking with them with my Note 4, I was breaking up several times. I think I was home every time someone complained that I was breaking up.
This is my first phone ever with Verizon and so far the data signal has been flawless, always super fast. I am worried though that my radio signal on the phone isn't good, possibly a defective phone?
When I got into work this morning I left myself a 2 minute voicemail on my work phone and played it back to see if it was breaking up. I played it back and it was perfect.
Could my house just be a "bad spot" in the area? I'm in West Bend, about 30 minutes north of Milwaukee. My signal at home was about -101dbm and its about the same at work. If my signal/service is going to suck at home thats going to be pretty annoying.
Is there a number that I can call to update the towers? I know this helped on occasion when I still was with US Cellular.
PS. My wife got the exact same phone, I'll have to check to see what her signal strength is.
Thoughts?

Hello, I've moved your thread to Q&A as it's pretty clearly a question.
Thanks.

Do you have a case of any kind on your phone? If so, which one.

No case on my phone. So my wife just called me from home who also has a white note 4 and sure enough, the call dropped twice from her. When she is in the living room, it appears to be fine (I called from my work land line phone) but if she moves into our kitchen, the call starts breaking up.
My brother said my voice was breaking up too when I called him yesterday, also from my kitchen.
This makes it sound like its not the phone, but the signal in my area. This is troubling to me because we are in a town of 30k+ just 20 miles north of Milwaukee. We have never had a single call issue with US cellular or straight talk.
What should I do at this point?

When I first joined with Verizon, I was having a lot of issue with poor signal and dropped calls. I called them to complain, and they told me that I could either get out of my contract, or they'd give me a network extender. Because at home was the only place where I was having issues with the service, I opted for the network extender. The one that they gave me was refurbished, but it has worked fine for over two years.
Your mileage may vary, but calling them to complain is definitely worth a try.

That's exactly what I did. I told them that my 14 days is almost up and I want them to make a note on my account that if my signal doesn't improve at home, then I can cancel my service.
She did bring up a network extender but I said there is no way I'm paying for that. If they would be willing to give me one to use at home I would be ok with that.
So far I'm not happy with Verizon's coverage, which is funny, because that is what they are known for.
We have never had a single call reception issue when we had US cellular and Straight talk.

So they didn't give you the extender? They were very accommodating a couple of years ago when I called. They acted like they actually wanted to keep me. They were going to let me cancel AND keep the two S3s that I had just gotten. Before that, I had Sprint, and I'd have gone to two tin cans and string before I'd have spent another day with Sprint.
I used to live in Illinois, and aside from the area right near my house, the signal was pretty good. I'm in Colorado now, and Verizon out here is an entirely different story. LTE is a joke where I live. I get a decent signal, but download speeds are sometimes worse than 3g. There are only four communities out here with XLTE. I was considering going to TMob or ATT, so I asked some of my neighbors. They all said to stick with Verizon, so here I am.

They are going to have technical support first check the towers or something to that extent. She started a ticket for my complaint and are going to get back to me within 24-48 hours. If it doesn't improve, then we are going to talk about an extender. So far the only reception issues that I appear to be having is in my house.
Whats weird is the signal strength is the same at home as it is at work. I called my land line from my cell phone at work and left a 3 minute message of me babbling and not once did it ever break up. If the strength is the same, why is it cutting in and out and dropping calls at home?
Hopefully they can resolve this. They are going to give me an extender for free or I'm dropping them.

Sounds like a problem tower, or a tower that's too far away. Or a tower that's overly congested.

Well I hope they can fix it. Kind of ridiculous that I can't get a reliable signal in my own house in a town of 30k people.

Signal on mine is a little better than the S4. Call and text range is great.
I am happy with the signal overall.

I have noticed that people tend to not hear me at all when I have a call open to them
Alot of the times as I'm talking the opposite side keeps talking back words like "Hello, hello.. are you still there?" and all the while I can hear them perfectly. I swapped my Note 4 for a new one at the store and for a while I was good until today the samw thing happened again. Im beginning to worry that the antenna reception on this phone is not as good my old Galaxy S4.
Really hope it is just a software problem that can be corrected. I live in Finland and I have a non branded and non sim-locked Samsung Galaxy Note 4.
