Nexus 5 d820 not picking up LTE signal - Nexus 5 Q&A, Help & Troubleshooting

Hi , My name is Ramiro i am new i the forum.
I decided to make my own thread because i already tried all the solutions in this forum about similar problmes in my Nexus 5 d820 32gb white and I could not solve it
I will start from the beginning , i bought the phone from this website TAOBAO.COM about 2 months ago, the seller has great ratings and over 100 phones sold.
When i got the phone in my hands after 1 moth , i inseterted my sim card and the phone only picks HSPA+ signal, the phone works perfect in all the other aspects,
Now this is all the info about my carrier , and thinks that i already tried on my phone.
My carrier is Movistar From Argentina , my sim is LTE ready and i have LTE activated on my service, if i put the sim on my
previous LG Spirit it works perfectly with LTE, here the LTE band is band 4 AWS wicht is compatible with the D820 variant
I already set my vpn manually , i choose LTE in my phone settings.
I flashed the phones and put the latest Android image 6.0.1 MOB30H, i already did wipe data cache, and factory reset.
I am sure that its a D820 model , the imei of the phone is the same that the one on the sticker in the back and the one on the Sim slot, and i checked it on internet and it belongs to an D820
With H+ internet works great but i never had LTE ,not even the word LTE shows on the status bar
I tried running the APP LTE DISCOVERY in this mode "Auto-repeat cycle after LTE discovery " and for some moments it reconized some unknow LTE signal but for about 4/5 seconds and some "neigbhors" LTE cells i would love to show the screenshots but as i am a new member i cant attach outside links if somebody wants them send me and inbox, i think the can give some extra info,
What i need to know is if my LTE antenna is broken or if for some software reason my phone is not picking up LTE or if somebody knows some way yo prove if the LTE antenna is working or not
PD: sry for my bad english.

[Q] SIM Not Detected - Google nexus S I9020A

I recently bought an unlocked Google Nexus S from amazon. The Device works fine on ATT network. When I got it to India and tried inserting an Airtel SIM in it. The phone shows complete Signal strength but says emergency calls only. On the lock screen it says insert SIM.
When I search for available mobile networks it shows my network but unable to connect to it. It does not even ask for unlock code when I insert a SIM from another carrier.
Is this because the phone is locked or is there some other problem?

What network frequencies does Airtel use? If non of them match that could be why, oh and Nexus phones are never network locked
Sent from my ice cream powered Nexus S
Yeah, frequencies should be the reason here.
But only for 3g, the us always being special, especially at&t. ^^ 2g should work worldwide. Set it to "2g only" and see... (if it works, slow data, but at least you can make calls)
I got a Samsung captivate from ATT and it worked also my Galaxy S 4G. All these are quad. band phones so, they work worldwide. Could be some other problem. Got a good deal, so dont want to return it, but I guess I have no option now.
Tried a new sim?
im gonna be going to india in a month or so and i wanted to know if the i9020a will atleast work with voice in india. airtell or vodafone it doesnt matter. I don't need 3g but i was hoping voice would work so i could just use this phone in india.
did you try to reset the phone?

Using PR 5.1.1 on Tmobile --- What are the best settings?

Hi Everyone,
I picked up the phone during the EBAY $249.00 sale and really like the phone, however I hated the ATT Bloatware.. I flashed the PR 5.1.1 firmware and really like how clean it is, however I am not getting good speeds on Tmobile. In the mobile network settings there is no option for LTE. I have gone into the service menu and changed the band to 4 and can get LTE, however it is really slow, I have also chosen band 17 and getting OK speeds using HSPA+, however no LTE and when I reboot the phone it resets the bands to the default settings...
Any one have any ideas or suggestions?
Thanks,
Chris
I am also having the same problems. I actually have a working AT&T SIM, and I can verify the LG phone can pick up LTE 100% , but with a T-Mobile SIM I can only get HSPA+ (using LTE discovery). I am testing this literally in front of the T-Mobile headquarters in the Seattle area, so I think this is unlikely to be some sort of cell tower issue. My iPhone is using LTE in the same location without any issues. When I use 277634#*# and select band 17 and GSM/WCDMA/LTE Auto , it seems to trigger LTE once a a while, but it never holds for too long.
By the way, I am intrigued that someone in Youtube says it is possible to enable band 12 for this H950 model (just search "band 12 LG Flex 2 T-mobile" in Youtube). Maybe this is fake info?!?

[Q] SM-G995FD on Freedom Mobile LTE

I have been trying to get my LTE working on my Samsung S8+ SM-G955FD with Freedom mobile. I have updated the CSC to XAC and GLW from the development forums and the phone will not connect to LTE at all. However flashing it to tmobiles CSC I was able to get LTE as it uses the same band 66. I initially got LTE by selecting the network operator "Home" once I lose connection from LTE to 4G it will not automatically reconnect back to LTE unless I select the network operator again. Any suggestions on fixing this?
Same issue with Reliance JIO (India) using VO LTE. Seems the phone does not support it either (the 6GB Ram Model)
up!
my 3g does work but lte not always!
I found this article around flashing csc, it seems like it's proven to work when they are the same model eg both g950w.

I would like to ask if you rooted your phone and changed the CSC as per instructions given in the Droidview website?
If you did, and the results were not satisfactory, then you would have tripped Knox, but gained little.
I am in the same situation, and am considering rooting the phone to try the method in Droidview.
Thanks.
I got s8+ from freedom and trust me I absolutely hate their reception. On a drive home or from I get interruptions of voice call for 5+min (highway drive) in some areas. Anywhere in US call reception is hit or miss. In Canada isnt always great other. Now for LTE well, it ok if you catch LTE signal. Allot of the times im on 4g. Speed are very slow. If im lucky I get LTE. So i don't know whether its the service or the phone but im not happy. I'll pay of this phone and move back to FIDO or on US network. Freedom is garbage to me. Im all over the city, country and north america - freedom isnt great for me. Fido was excellent but i didnt get any credit on the phones, in US fido rates are very high.

Galaxy S8 Supports All Available Lockal Bands But No 2G

Hi. I got a BoostMobile Unlocked Galaxy S8 off Ebay. It supports all available 6 bands (two bands for each 'generation'). Immediately after first use I realized something was wrong with the signal reception. Long story short, it wont connect to 2G network. I am really skillful with technology and I tried every possible way to test what I am declaring right now. The thing is, when 3g signal is weak, phone says emergency calls only. 3G and LTE are ok specially outside. I was adviced to replace the Motherboard. Do you guys think that is the only way to remedy this issue? FYI i flashed the firware with various carriers but I finally sicked to unlocked one(U1).

VOLTE On TMobile & ATT?

will volte work out the box for TMobile ? They won't activate phones on their network after a while if they don't support VOLTE.... Or any plans to update it in the near future. When will this go on sale in North America?
Sent from my ASUS_I01WDX using Tapatalk
I am currently on T-mo, it doesn't do VoLTE currently, I know its possible via root and changing parameters. ALSO they just enabled VoLTE for their ROG phone 3 via an update so I will assume they will probably do the same for the ZF7, if not I will have to root it.
I asked an asus rep about sale in NA and they didn't have an answer from marketing team, so I bought mine on eBay
I'm beginning to think they will sell in in america especially if they enable volte for TMobile like they did the rog 3. I'm waiting to see if they enable volte on the 6 and the 7.
And then there's the OnePlus 8T coming in going to weigh my optione

This guy apparently has VoLTE already on his phone, unsure how though.
Will this work on att in the states? Also which model if so?
ATT will ONLY work upto 3g. You will see an H on top the signal bar which indicates a Enhanced 3g speed also know as HSPA speed connection. I have tried 2 new sim cards. I have tried several APN's I have tried all updates and a reset. No 4G and no 5G on ATT. Unless someone can tell me something new, this phone will not FULLY work on ATT. Text works. Calls work. Internet is sort of hit and miss with decent signal but again rather slow.
T Mobile will ONLY work upto 4g. No Volte although it seems to have the capability of Volte it cant not work with Tmobile Volte because it seems the cell bands are not compatible. Text work. Internet works rather fast, Good solid signal however no 5G and no Volte due to incompatible cell bands.
I did research on this subject and found that the ATT cell bands for everything including 5G do seem to be compatible with the 7 pro but again, it does not FULLY work oddly
I also did research on Tmobile cell bands and the bands for 5G are not even close to being compatible. Volte is also non compatible. 4g is compatible and works..
THIS IS MY OWN PERSONAL EXPERIENCE TODAY AS I PURCHASED A SIM FROM EACH PROVIDER ( THIS IS A DUAL SIM PHONE) AND PLACED THEM BOTH IN THE PHONE.. I DID EXTENSIVE RESEARCH>>>
IF ANYONE CAN GET THE PHONE TO DO 4G or 5G ID APPRECIATE THAT INFO>>
ASUS NEEDS TO DO AN UPDAT FAST BEFORE PEOPLE START TO RETURN THIS DEVICE. THIS AGE IS ALL ABOUT 5 G.. THIS PHONE IS NOT COMPATIBLE WITH USA. I DO NOT SEE HOW AN UPDATE WILL FIX THE PROBLEM SINCE THE PHONE IS ONLY PHYSICALLY CABLE OF A SPECIFIC SET OF BANDS WHICH ARE NOT NOT NOT THE SAME AS USA BANDS
