No,
The earlier variant D802 does not support 2300 Mhz (band 40) frequencies. You will need newly released variant.
But I have used my D802 in Singapore and LTE works there. The new USIM will enable LTE in network selection menu. So you will have to wait for Vodafone or Reliance to deploy LTE in 1800 or 2600 Mhz.
Moreover, Airtel's 4G is a piss poor effort. It's capped at 10Mbps. They have become a laughing stock. My Vodafone 3G touches 15 Mbps on a good day.
Also the 4G is data only and VOLTE (Voice over LTE) has not been enabled by Airtel yet. So you cannot get continuous 4G data. If you receive a call, it will fall back to 2G or 3G mode.
I hope this answers your question.

[Q] no 4G in China

My Samsung Note 4 N910C had great performance under all 5 operators when I was in Hong Kong, with unbelievable 4G speeds...
Now I am in China, using a 4G enabled SIM card from China Unicom and the icon on the top bar only shows H+.
By contrast my iPhone 6 and my LG G3 show 4G, both of them. Under the same conditions, same network (China Unicom) and same 4G SIM card
I asked China Unicom: they run a 4G FD LTE network, in 1800MHz band. So what could be the culprit? Are we sure that Samsung SM-N910C covers the FD LTE 1800MHz band?
(LG G3 and iPhone 6 plus do for sure since I get the 4G icon on top bar)
Thank you and waiting.

OTA routine updates + Phone call recording
I have other 2 questions
I wish to root my device: (using chaifire Auto-CF method).
1. OTA routine updates
What will happen when I make an official OTA monthly upgrade, from Samsung? Will I get the device bricked? Will I lose rooting?
2. Phone call recording.
For many reasons I wish to avoid to flash a custom rom. How then can I get the capability of "phone call recording" during a phone call? I have this feature with my NON rooted MIUI M3 device...running android 4.4.2. Are out there any apk to install or special mods?
I am not asking about privacy concerns or the legality of phone recording, I just wish to know if that function is feasible without flashing a custom ROM.
Thank you
Saulo

As far as I know china mobile runs FDD band 3 (1800) and band 7 (2600) ONLY in Hong Kong. All other parts of China using TDD. As far as 910C I can assure you it has band 3 (1800) because vodafon qatar uses that band.

Thank you.
I am using China Unicom, not China Mobile, but, yes, both carriers are currently sharing the TDD LTE network
So we have to admit that LG G3 has both FDD LTE and TDD LTE? Otherwise why my LG G3 shows a 4GB icon on top bar? Of course I am using the same 4G enabled China Unicom SIM card

The 910G should work in china as it supports TDD bands

Really strange as both your 910c and the Unicom 9106w both list B3 (1800) in their specs so it should work.
Any way to get into the settings and force LTE only? Do the APNs look OK?

Dear Kinghu
How to force LTE? In settings I only see
WCDMA only
WCDMA/GSM
GSM only
2.
In Hong Kong I saw 4G icon. But at that time I did NOT check in settings, Anyway the speed was so good! I downloaded an entire movie is less than 6 mins. Incredibly fast. Here I am back to average speeds.

I just bought a 4G china unicom sim card and receive H+ as the symbol.
I called Unicom and asked them why and the guy told me that iphone symbols show 4G but android and some other devices may show H+ but it's still 4G speeds..
Is that even possible? My HTC One can use 4G but it's showing H+, I didn't think H+ could be shown if it actually uses FDD-LTE..

[Q] N910K LTE Band problem

Hi
I recently brought my N910K with me from Korea, and just got a new simcard. I have cell service, but no 4G LTE. I do get 3G service. So, I figured if I can change LTE band on my phone, I should get the service. Since I am paying for it, why not you know? Anyway, is there any way to change the LTE band or am I stuck as is?
Thank you and sorry for being a noob

Dual-SIM SM-G9287 in the UK

Anyone using this phone in the UK? Any problems with it, i.e. connecting to 4G etc..... Thinking of buying the sliver version, and want to make sure it works ok.

No problem at all. o2 network - No 4G. max is HSPA+. EE network - all LTE bands. Even 4G+

When you have both SIM inserted, do both run at LTE? or 1 of the SIM is 2G only?

One is LTE one is 2G. All dual sim mobiles doing same.

Yes. it works like that.

I'm currently in Australia and like the look of this dual sim phone. The specs say it should be 3G on both SIM cards....is this not possible in UK because of the SIM 2 bands ? I don't want to by it at just under A$1000 and get back to UK to find it doesn't work well due to network compatibility issues. I have tried reading the country network bands info online but I don't really understand if the uk and Europe can make use of the LTE band or not....... I frequently go UK and France (live in UK) so anyone know how this phone will workout in these countries.
I forgot to say that I'm on a Three network SIM in UK. (Long live the "feel at home" features they offer!)

I own this model and both sim use lte but you cant use them at the same time.

Thanx for your reply. Would you say it's a good phone for use in the UK or would you buy a UK model if you had the chance to change again?
It's just that there are not many dual phones available in UK.......
Currently I use an HTC m7 dual SIM.

It works perfectly fine in UK, But I advise You to Use EE UK. They offers LTE cat.9 (4G+). o2 doesn't support 4G on that phone. I don't know about rest networks.

Ok thanx, I will check what THREE network does. I saw your earlier post when you just got the phone and you asked a similar question as me about 4G so I guess your issue was service provider then and you now on EE.
Can you advise me one more thing...... If you put your EE SIM in to SIM 2 shot does it still work on 4G with data connection on SIM 2?

check if your carrier support this following band.
Cellular Networks: GSM850, GSM900, GSM1800, GSM1900, UMTS850 (B5), UMTS1700/2100 (B4), UMTS1900 (B2), UMTS2100 (B1), LTE700 (B17), LTE850 (B5), LTE1700/2100 (B4), LTE1900 (B2), LTE700 (B12), LTE800 (B26), TD-LTE2600 (B38), TD-LTE2500 (B41), TD-LTE2300 (B40), TD-LTE1900 (B39)
Cellular Data Links: GPRS, EDGE, UMTS, HSDPA, HSUPA, HSPA+, LTE, LTE-A

G9287c

I checked and THREE network sports LTE B2.
But what I would like to know is if sim 2 is selected for the preferred data connection, well it connect on LTE or 3G or like my HTC m7 dual SIM only 2G?
Could anyone try this for me and let me know. I have seen different advice on different sales sites so not sure.

Both sim card slots offers LTE. You just need to choose which simcard need to be LTE. You can swap LTE between simcards without removing it. Thing is, that You can use LTE on one sim, other one will be 2G. No way to get 4G on two sims at the same time.

Thank you for testing and letting me know, I don't need 4G on both slots at the same time, so that works for me.

hi
could you help me?
is dual sim edge + supports two sim regarding CALL receiving? I mean, while I speak on SIM1, can I receive CALL WAITING(forwarding?) within that call duration?
at least a BEEP or someting, that SIM2 is just about to receive a call, WHAT I can answare, by HOLDING the calling on SIM1?
thanx

Can anyone tell me how many versions of the s6 edge plus G9287 duos are there? and what bands will they work on in the uk? thank you.

s7edge changin network band

Hi. Since I got s7edge ,i have been having some really bad network signal. I barely can got 4g with 1 bar,even though i have here good coverage for 4g .however,i have 3g and 2g full signal.With other phones i have had (p10,s7flat,htc one m9) i got full bars LTE+ signal. What could be the problem? I assume network band. I tried changing it on *#0011# but i cannot enter band options. I got sac23 v8 port.

"sac23 v8 port"
That's your problem. Get the original software if you want stability and reliability.
PS: You didn't say what hardware version of the phone you have and what cell network you are on. There are too many combinations for us to guess.

@SoNic67 Hm. Sorry,didn't think you would need hardware version.. i had same problems with official stock firmware and rom,thats the main reason i rooted my phone. So ,my hardware version is MP 0.801 and I'm on Serbian network,company name is MTS. We have some solid 4g coverage here..

Based on this, MTS has LTE Band 3 and Band 20.
Note that what is called 4G in Europe is technically LTE. So it means the same thing.
Looking at cellmapper.net, in Serbia, outside Belgrade, I see on MTS a lot of cells only with B20.
I don't know about Serbia, but in Romania I know that band 20 is a shared band (10MHz) by all the providers, in rural areas, so the connection to it is very unstable (I am not sure who has priority in case of congestion). I often saw there only 3G signal when B20 was overwhelmed. The actual speed test in those places was identical on 4G/LTE and 3G (H+) - the back-haul connection was limited.
Also, I am not familiar with your hardware version. Some versions have differences in supported LTE bands.
So... I would investigate that - what bands are actually implemented in your modem. Flashing different firmware won't change that, it's in a different memory.
I would start looking at this, at least to read the NV #06828 value (phone doesn't even need to be rooted):

Try *#2263# to change bands manually.

its not working

Take the SIM out first, reboot and then do the *#2263# without SIM inside.
However, note that when changing the SIM, the CSC file is re-flashed the modem with the appropriate bands and different restrictions (including locking service modes).
On my S7Edge, only with an AT&T SIM I can see the *#2263#. With Verizon SIM it doesn't work.

Mines Canadian g930w8, maybe it's in the CSC or modem as ours is different. Maybe not the ROM as I am on _alexndr's devbase.
