LTE Problem - G2 Q&A, Help & Troubleshooting

Ever since I took OTA update I cannot get the LTE to stay locked on it keeps going back to 3g. My wife has the same phone and hers stays in LTE. So I know it isn't the towers. She took the OTA update also. The only difference is mine is rooted on the new KK. Anyone else have that problem? Sorry I'm on Verizon Network VS980 4gG LTE

Well I downgraded back to Jelly Bean VS98012B and stayed stock without root and still have the same problem with LTE. I switched Airplane mode off and then back on and I get LTE with 2 bars then it goes back to 3g with 2 bars. I wonder if its the phone or if I am being throttled by Verizon?

Well I seem to be answering my own questions. Turns out my sim card is bad. I tried my wife's and the phone went to LTE and stayed. I put mine in her phone and it stayed 3g. So hope this helps anyone else that would experience this. Glad its not the phone.

I'm actually having the same thing... keeps switching to 3G randomly, after a reboot it'll go to 4G LTE and usually stay, but often if I make a call, or do something it'll switch back to 3G for some time, then maybe go back to 4G... stock KK rooted here too
Did the SIM card fix it for you permanently? I may try getting a new one if so.

I'll second this. Had the same problem. New sim card and bam, fixed. For some reason I think going to international ROMs (cloudy and optimus) caused this.... The 3g roaming thing.. which is a shame because their ROMs are freaking awesome.

Yeah I went to my local mom & pop Verizon store and the idiot behind the counter said my old LTE sim card wasn't NFC ( Near Field Communications) complaint. Why is he an idiot that's another story. But I don't know how NFC has anything to do with the sim card. Anyway I bought a new one because they weren't a official Verizon store, supposedly the official store will give you a new sim card. But now the phone works like it is suppose too.

LTE Sim Card Authorization Error

anyone with the 4g LTE experiencing this error?
yesterday (December 6) my Xoom mysteriously gave this error while doing absolutely nothing on my desk. I rebooted it twice and wipe clean LTE sim card and reinserted it. at first i couldn't get any connectivity to verizon services the whole day. but this morning i saw the 3g service come back online, but still i'm getting the 4G LTE sim card error.
i tried to google search this problem and only found one post that coincided with my time frame. is there something wrong with my xoom or is this verizon fault?
Noticed the same popup this morning, rebooted and it went away and came back...
Haven't messed with it yet. Good to know I'm not alone.
Also having the same issues with my Xoom. Didn't have any connection at all yesterday but this morning 3G is working. We'll see if they can fix this.
Its an issue with the 4g outage some sim card's data was erased just get a new 4g one and it fixes it did it yesterday and now it works fine

Just got off of the phone with Verizon and they said that there is a 4G outage and that they're working on it.
That happened to me this morning but was fine after a reboot. The possibility of this thing screwing up even more makes me want to demand that Verizon let me out of this contract as I've had nothing but crap from them and Motorola for 7 of the last 9 months.

Wouldn't you atleast be able to get 3g service if that were the problem?

I am at work now which only has 3G coverage and it seems to be working OK. Just have the annoying message. When I get home (which has 4G coverage) we'll see whether 3G still works.
Ha!! This just happened to me a few minutes ago. I got the Sim Card Authorization Error & my phone has been freaking out for the last hour or so. Having flashed a new 4G ROM this was waaay to coincidental for me. Glad (bad word choice) to see other people are having the same issue too.
It's Verizon's network.
http://www.gottabemobile.com/2011/12/07/verizon-suffering-4g-lte-outage/
Having the problem too and I'm completely stock.
Same problem here and also stock.
Back home (N central NJ) in the 4G coverage area, my Xoom is bouncing between "No Internet Connection" and "Verizon Wireless 3G". It doesn't stay connected to 3G long enough to be useable. Stock 3G Xoom, upgraded by Motorola to 4G and running the recent 3.2.4 update.
Earlier at work (NW NJ) in the 3G coverage area, things were stable.
Not seeing the SIM card message any more though.
Same here. Just got the sim card authorization error. Glad I'm not the only one.

It's a network issue with Verizon. My XOOM is giving me the same error. When I called tech support today they couldn't tell me when it would be resolved, but apparently it's affecting almost all 4G phones and tablets in the northeast area. Hopefully it will be resolved tomorrow.
My 4g is working normally now without any reboot of any sort. Guess Verizon fixed it

No Service and Unregistered SIM on Bell GSIII

hey guys, i got my GSIII for Bell about 2 weeks ago (and Bell has an LTE network). so a few day sfter i got it, i got no service at a place where i always get 3-4 bars, i rebooted the phone and the problem was gone. it happened again the same day and i rebooted again and it was fixed again. nothing has happened since, until yesterday. i was on my way to work and took a glance at my phone and it said unregistered SIM, so i rebooted it and it took a few minutes for it to gain access to the network again. today it happened again and i rebooted again and got LTE and HSPA back. has anyone else had this problem at all? it kinda sucks seeing as i paid full price for it and its acting up like this. any help would be appreciated
thanks
Get a new sim from Bell before you swap out devices.
Sent from my AT&T Galaxy SIII (SGH-i747)
ya ill try that, hopefully its just a faulyt sim or something
I have this problem too. Think it may be the device as I've had two Sims (first one wasn't lte) keep us posted might try another sim to be sure
Sent from my SGH-I747M using xda premium
ya im going in tomorrow to get a new SIM, hope they dont charge me, ill def keep u guys posted
this has nothing to do with the SIM. I have the same problem (also with Bell) and I called them. They are aware of this situation and are working on a solution. Usually happens when you go from LTE to HSPA.
They told me to switch my settings to GSM/HSPA instead of GSM/HSPA/LTE until its fixed. My SIM is new btw.
Have you tryed doing a battery pull? There is sometimes temp data that causes issues and a battery pull fixes it. When I got my S3 on launch day they said there was a delay in the network so it will be about 30mins before it shows registered SIM and works for me almost 3hrs later still no service. Went to my rep and asked me if I did a battery pull said no only tryed rebooting. Once I pulled the battery wait 30sec and put it back all was well. Try that if the issue is still there them most likely a SIM card problem and you need to go to a Bell store and sort it out.

and by changing to GSM/HSPA has it stopped the unregistered SIM problem so far? cuz LTE isnt a huge deal for me to have right now
that would be unfortunate as LTE is something that I really use now that its turned on at my workplace. If thats the case I hope an update comes soon.

of course, like I said , they are aware of the problem.
I change it back to LTE when I need speed (tethering).

ya the guy at the bell store told me to do the same thing today, said their LTE network is messed up right now and its not just GSIII's that are having these problems..on an aside, this morning i had my phone fully charged and had a 4 hour shift at work, at the end of the shift, after barely using it, my battery was at 7% ridulous, he said it was prolly cuz the phone was constantly searching for an LTE network, hopefully switching the network now increases my battery life!

[Q] Data Issue VS980 - Verizon

Basically I have tried stock reset using LG Flashing tool i have rooted and tried numerous roms, but the problem is i boot my phone it has 4gLTE full then 5 minutes in it switches to 3g network. I have called verizon and tried everything they told me. Also i have even tried and made sure it was on the correct network which is Global or CDMA/LTE
I wanted to know if any deveopler can help me here to figure out the issue with why its not staying connected to 4g?
One of two things. There is issues with the towers around u which would be a Verizon problem. Or its hardware related

its sounding like its hardware related before i upgraded to the LG g2 i had .. i even dialed *228 to locate towers my area is all red on 4glte and im right next to the tower
can someone please help me with this issue it is irritating me very much because i pay for 4glte not 3g ****
so no update on this no one having the same issues as me loosing 4glte and connecting to 3g
Have you tried a new SIM card? On some LTE devices dialing *228 can actually screw up the SIM data. You should try a new card.

Have you tried any of the different radios / modems? Might be worth a shot.

Just got my G2 a couple days ago and I can confirm that I am having the same issue. I haven't found any fixes yet. It does seem that as long as I am actively using the data network, I keep 4g. Once I quit using data or go to wi-fi though, I switch back to 3g after a short period. Quick toggle of airplane mode and almost instantly connects back to 4g again, with the same results of dropping shortly thereafter.
I'm in a spotty area, 4G sticks on one bar and rarely reverts to 3G. Signal loss very rarely. Always comes back auto. Faulty modem sw, SIM, hardware, or towers.
I called lg about the issue they say it was Verizon's fault and there radios .. So they sent me the international version works perfect now I would recommend anyone here to drop Verizon they are **** and highly overpriced

[Q] LG G2 D800 AT&T voice calls drop 4GLTE to 4G

Hi guys I searched the forums and didn't see any mention of this besides somebody with a Sprint version of the phone talking about it. I bought an AT&T G2 D800 over the phone with them, they shipped it to me and it was fine for a day or so until AT&T rolled out the D80010o firmware then my phone started getting strange battery drains and in call volume setting keeps reverting back to 90% every time I reset the phone, so I brought it in and exchanged it for a new one. Herein lies the problem.
On this new G2, I noticed that every time I would go to make a call, the signal drops down from 4GLTE to just regular 4G. That never happened to the phone I brought in to exchange. Granted I don't remember making a call before I did the firmware update so I can't say for sure if it did it before the software update but I doubt it since the notes on AT&T's site said it was mainly making the phone ISIS capable. The reason I noticed the difference right away was because up until that point I'd never seen the 4G icon on the G2, so I saw it right away. I was still in my car testing the phone so I came back into the store to ask them if that was normal, they said it was. One guy even said it happens to his iPhone too. Since there was 3 of them saying it was normal, I walked back out. I went home and did some more research and it seems like the G2 supports "LTE (SVLTE, CSFB, CA, VoLTE, RCS, MIMO)" taken from: www lg com/global/g2/sub3 html (sorry it won't let me post outside links) and also like I said, my previous G2 didn't do that.
I need help confirming from other AT&T LG G2 D800 owners that their phone doesn't do the same thing, that when you make a voice call in an area where you're getting 4GLTE, the radio doesn't drop down to just regular 4G. The minute I hang up it goes back up to 4GLTE and I'm staying still in one spot so it's coverage, and my entire has always had LTE coverage. Please let me know before I bring it in for another exchange as the AT&T I went to the customer service was terribad, I'd like to go in there with certainty so that if push comes to shove, I'll just tell them to open a new G2 and test it on the spot to see if it does that. Any help would be much appreciated, thank you.
Confirmed on the 4GLTE -> 4G on voice call -> 4GLTE.
Never paid attention b4 and don't know whether it supposed to be that way or not.
And yes, with the D80010o firmware, battery seems to drop quicker than expected
Thanks for the quick response and apparently being the only LG G2 D800 owner on this forum. Yeah I haven't updated this phone yet and battery once again runs like a champ.

Your phone will drop to 4G until VoLTE (voice over LTE) rolls out possibly next year. It's been like this for a while, so don't think there is something wrong with the device.

I know this is a bit off topic but is there a separate 4G LTE icon in the notification (status) bar? All my other phones have had the 4G LTE icon there when I'm at home but this phone always says 4G
You guy the software of lg g2 if really bad your phone does not know when to change to 3g 4g or 4lte its not just att is all lg g2 the update is supposed to fix it but that wont happened as you can see. Try to update prifile and prl to see if it help.... mines its fine now after i update

Nope, there isn't. The 4GLTE disappears the the 4G icon replaces it at the same spot or vice versa. I'd try turning off the phone for a while and then turning it back on, or swap out the SIM. The guy at my AT&T store told me sometimes it's an activation thing where it can take a day or two to be "fully" activated and get full 4GLTE.

Thanks... not quite sure what you're talking about with the link though but I'm on AT&T... AT&T/T-Mobile are GSM and don't have PRLs to update... that's a CDMA Verizon/Sprint thing.

Can't use Internet while on phone

My s4 could do this. now it gives an offline error. What the hell is wrong with the s5? It's like they hired someone from iPhone genius product team. This is a step backwards. Also phone never connects to 4g. Probably a personal problem

Sounds like the problem is one in the same because if you aren't on 4G (or wifi) you can't simultaneously talk or text and use data.
Do you know if other phones in your area get 4g? If so, try roobooting/ re inserting your Sim card. You could also try to change your network from "global" to "LTE/CDMA".
My RAZR had this problem all the time and usually a reboot helped. Or 4g could be out (was out for a week in my town).
Did the geniuses at Verizon give you a new SIM card with your S5 our use your old one? When I got muy S5 they tried to use my old one and it had all sorts of problems, the next day I went back and a guy who knew what he was doing asked the very question I opened up with and I told him the reused my old one, and here told me the came with a new one for a reason! He switched it out, all little bugs gone, worked great until the camera gave out, but that is a different issue!
Thank you all for the replies. costco rep advised me to call tech support so I'm giving that a try before taking back in for 2nd return (first return for defective bluetooth)
They originally had me use my Sim card and took mine out the phone that it came with. Then the NFc didn't work because of sim. So i go there and get a sim they pulled out of another s5 like they did mine and told me to call Verizon to activate it.
Thing is. 4g was working fine on that phone. Bluetooth was the problem and now on this device the 4g. I think it's the 4G hardware...
Sent from my SM-G900V using Tapatalk
Right.. Hardware related.
but yes.. you can only use data while on the phone if your phone has 4g or on wifi since 3g uses the same signal as your calls do so fix the 4g and you should b good to go
