Hi - I have LS980 on cm12 rom. I have subscribed to Airtel 4G connection however I was informed that LS980 does not support 2300mhz and hence 4G is not possible unless the Airtel also starts providing 4G connection on 1800mhz.
Would someone be able to guide/help me in letting me know if it's something can be done so my phone thinks I have 2300mhz, similarly like "QUALCOMM NV CALCULATOR".
Please let me know if this is possible to have 4G/LTE from Airtel in India on LS980?
airtel 4g
I think the only model that supports 4g lte in india is d802t. Airtel provides at 2300mhz only...
Hello i need help about 4g.
i Bought sm-900i from u.s this summer. i`ve been told that this device has 4g lte,(also on spesifications in internet and back cover has lte logo) but i never saw that option and cant use it why ?
Right now im living in lithuania and the operator i use provides 4g from 800 , 2100 ,2600 only 800 is not supported by my device.
On options in the phone when i go into the settings in phone under mobile i cant see any LTE on network mode only 2g and 3g which i attached the photo what may be the problem please help.
Can someone please help ?
help please
If that model S5 100% supports 4G, then the problem is with your carrier/provider or coverage
i have note 3 n9000 with gsm band support ... is there a way that it can support cdma and lte 4g bands .... when i removed the battery the sim slot is of 4 pins that means it can suppot lte also but the phone only shows gsm/wcdma options. is there any way to modify this ?
Hi, I have a note 3 n900a lte which one I check
mm in theory the phone conect to lte 4g in mexico band 4b for telcel
you might check if the phone model supports 4g
you must a chip compatible with 4g for to network provider
could you check in service mode *#2263# which type of conection have the phone
and for last your phone must have been unlocked by the network provider
sorry for my bad english I used traductor ... :; XD

Have you tried to change nertwork mode to WCDMA only or GSM...or both WCDMA and GSM...????
Hi bro I am from Pakistan too so I research on it (couz I got 4g phone as well) I tried zong and didn't received signal so what I found is that these networks are on limited bands to work u need both phone and network to be same frequency supported to work 4g (and don't ask me how to do it couz I don't know either) try using warid (if possible) 4g it probably gonna work (not sure) or maybe you are not in 4g coverage area....
READ THE [UPDATE] DOWN BELOW
Many Note3 Korean Variant users also reported this case
https://forum.xda-developers.com/showthread.php?t=2484602&page=115
The problem is that, I can't connect to LTE without losing my Network Radio Service Connection. I can connect to E/G/3G/H/H+ and still have network service, so I can still make calls and text messages, but when I turn on my Mobile Data, when it tries to connect to LTE, suddenly my service gets diconnected and I can't make phone calls nor messages though I could still use the data. I've already tried 3 LTE-Capable SIMS but the issue still happens.
What I had in mind is that it might be because it is Carrier Locked since it is a Korean Variant, but the problem still persists even after flasing other custom roms (this includes Note 7 Port ROMS, LineageOS, Stock-Based ROMS).
I love my Note 3, I will do anything to keep it alive, but still this one problem keeps bugging me...
Why can't I use both LTE data connection and radio service connection simultaneously?
Is anyone out there knowledge and willing enough to help us Note 3 KV users with this issue? :crying:
[UPDATE]
I get it now, when a phone is using LTE it means its not connected to any Mobile Network Service, instead it is connected to Data Network Service, yet it should receive Phone calls and Messages but it means that the phone will disconnect to LTE and switch to GSM/WCDMA (E/G/H/3G/H+) to be able to recieve the incoming call or message. I've tried that with my friends' phones, The first phone is connected to Data and is using LTE and the other phone is trying to call the first phone. The moment I call the first phone, I noticed that the LTE icon dropped to H and then recieve the call, It only happened because the option selected on the "Network Mode" (under Settings/More Networks/Mobile Networks-->Network Mode) is [LTE/WCDMA/GSM auto connect] so that's how it works
But that doesn't happen to my phone, after turning off the Mobile Data (I was connected to LTE btw) my phone doesn't automatically connect to GSM nor WCDMA network, it just stay on LTE mode and I have to manually select the GSM/WCDMA option in order to get Network Service.
So my final question is Why doesn't my Note 3 automatically switches Network Mode?
Note 3
Model Number: N900L
Status: Rooted with Custom Note 7 Port ROM
Condition: Good, No History of Repair
Current Network: SMART Prepaid
Does it work on genuine non custom stock firmware ??

No it doesn't, the problem is already there even before I rooted my device. Flashing stock lollipop rom on odin didn't help either

Please start to read about LTE technology and its frenquency bands.
Then find answers to these questions :
1- My SM-N900L is locked to use which frequency bands ?
2- Wich bands are in use in my actual location (country) ?
3- Is it possible to unlock more frequency bands for my N900L ?
i can provide more help if things remains not clear enough.
Good luck :good:

I tried searching the supported LTE bands of N900L but I can't find any sites that tell exactly what the N900L actually supports though I found out on this forum
https://www.frequencycheck.com/models/AZzWA/samsung-sm-n900s-galaxy-note-3-lte-a
1) A / P / T / V models are made exclusively for the US operator market and for no other people, as their indexes hint (A-AT & T / P-SPRINT / T-MOBILE / V-VERIZON). In Europe, mainly international versions are used - in the case of NOTE 3 - exclusively N9005, in Canada - its own carrier versions.
2) The models N900S / N900K / N900L are identical in the set of supported frequencies. If you rewind the topic on page 9, you will see screenshots of one of these models, which show the frequencies you are using, in one of the screens you will see the treasured frequency of LTE b7. I think that users of this topic can be trusted with respect to information in the topic, but no one has elected you the right to believe solely on the site www.frequencycheck.com.

I did try checking my phone on www.frequencycheck.com, N900L is not on the list..
https://www.frequencycheck.com/models/AZzWA/samsung-sm-n900s-galaxy-note-3-lte-a
N900S though shows that it supports Bands 3, 5, and 17.
I also look it up on wikipedia on where the SMART network (my current network) falls on the list of LTE frequency bands, and it shows that it is on Band 05 alongside with South Korean Networks LGU+ and SKT. The supported LTE bands on my country are Band 1, 3, 5, 7, 28 and 41
https://www.frequencycheck.com/countries/philippines
I searched for how to unlock all LTE frequency bands on N900L or Korean Variants or Note 3 but the only option that shows up is by accessing the Service Menu on Stock ROM and manually changing the values, which still didn't work for me.
According to my search, N900L is locked to :
LTE protocol : B1 (2100) and B5 (850)
LTE-A protocol : B3 (1800) and B7 (2600)
Now try to find the specific frequency band used by your carrier (he can't use all of the six available bands in Philippines), and activate it.
Wich stock firmware do you use when trying to access Service Mode ? It must be the LGU+ one.
And what code did you dial for the same purpose ?

When you said activate, you mean select the band to be used by the phone right?
- Yes, I used the LGU+ Lollipop Stock ROM
- I typed in the dialpad, *#0011# and changed the network preference to LTE ONLY.

I mean activate only the LTE's frquency band used by your carrier.
Check your PM.

I've already done that, but the problem with radio service network is still present, I can't make or receive any phones calls nor messages.
