[Q] no 4G in China - Galaxy Note 4 Q&A, Help & Troubleshooting

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.

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..

Unlock the LTE lock adout N9005 in CHINA?

I buy a Europe N9005 via Gray way, but I cann,t use LTE of CHINA UNICOM LTE inCHINA WUHAN
anybody could help me ?
i only know xda is a brilliant rorum:highfive: i hope i can solve my problem
So, did you check the provider's LTE frequency band against the ones the N9005 supports?
Because there's a 99.99% chance the two don't match. Which XDA can't fix. (We wish!)

:crying::crying:
MY Europe 9005 (32G) said it support LTEB1 B3 B5 B7 B8 B20 ALL
LTE of China Unicom is Band 1 /Band3 ,I think it should be supported. AND the 9005 of Hong kong, it could use in CHINA UNICOM'S LTE,
the 9005(TGY,16G) should be same with 9005(EUR,32G) in hardware
And many of Europe N9005 the IMEI will change if you flash new rom with odin ,IMEI will become 35750705000888 ,many people suffer that.
So i guess Samsung Lock the LTE because of religion place restrictions ,i guess
CHINA UNICOM said its TD-LTE is false, because goverment force them to use TDD-LTE , a lot of cities use FDD -LTE in fact .
CHINA UNICOM use TD-LTE band 41, FDD-LTE band 1 ,band 3 even band 7
So, what's the current situation in China ? I am at the same position; unlocked international version of Samsung Galaxy Note 3 (SM-N9005) and want to use it in China. Mysteriously, 4G seemed to work (??) with a China Mobile sim card when I tried in a mobile shop but sadly I didn't have the time or access to make sure and do comprehensive tests. I thought TDD-LTE was not supposed to be compatible. Could China Mobile have FDD-LTE in my region (Henan) ?

[Q] How to check 4G capability on Redmi Note 4G?

Hi
I have Xiaomi Note 4G (China Unicom version) but I am unable to use it on FDD1800 band on Zong 4G network in Pakistan. I have a 4G SIM that works perfectly with my LG G2 D802 and Huawei E5375 (CMCC).
On the box its written both LTE TDD and FDD and it does show 1800 band but when I force it to LTE-Only using Phone Testing menu (*#*#4636#*#*), it goes to no service.
Is there a way I can test the phones capability regarding LTE FDD1800?
Thank you in advance for your help.
Regards,
Shoaib

I just got my redmi note 4g yesterday, And as ar as I can see, in the Upper left corner it writes "Carriername 4g". So that should indicate if it works.
Diferent version of redmi note 4g?
hello,
I'm thinking of buying the terminal , but I have a doubt
Viewing Page Xiaomi singapore , hongkong and taiwan offering a 4G LTE version band frequencies LTE 1, 2, 3, 4 and 7 , but I see in different Chinese pages to buy it appears redmi note 4G LTE but only with frequencies LTE 1800/2100 .
Anyone know if there are two LTE versions as might ensure you have the frequencies that advertise in singapore, hongkong etc.
Thank you .
there are 2 versions of the phone. One that is domestic China 4G and then there is the export version that supports FDD-LTE/WCDMA/GSM. I am running a 4G version in Hong Kong and its fast. Not a huge diff from my Sammy Note 3. For the price its like giving it away. Only thing now is how reliable it is. Sammy is super reliable.

Are there different versions of Nexus 6P for Europe and US ?

I was planing to ask my friend to get me a Nexus 6p from US and bring it over to Europe and I was wondering if there are different versions of Nexus 6P for US and Europe (with different sets of LTE bands ) ? Will I have a problem of using it with European GSM bands (specifically the LTE/4G) ?
Thanks

LTE/4G will be a problem
Agreed, the US version has less bands than the international version. It does not have band 8, which is what most of the UK's 4g network runs on. There are a few exceptions, but most of them work of band 8.

This, it's also missing band 20, which is used for 4G networks in the Netherlands and most of mainland Europe as far as I know. Basically a US Nexus 6P won't work on 4G/LTE in Europe.

Ahh, ok then :/ That was my shot to get this phone cheaper, it's ridiculous how expensive it is here compared to US .
Thanks for the response.
I know that here in Ireland Vodafone (my carrier) use both band 20 and band 3, with band 3 usage being more recent. I am doing my research at the moment but am hoping that if I get a US Nexus 6P I will be able to use it here with Vodafone LTE on band 3.
Crossing fingers,

Where can I find more info on these various nexus 6p variants?

US Version and International have the same amount of bands just different ones. No one in Europe runs on band 8. UK runs mostly on 3/7/20. So most likely you will get LTE coverage from your carrier unless you're with O2 or Vodaphone since they only support band 20.
US: 2/3/4/5/7/12/13/17/25/26/29/30
International: 1/2/3/4/5/7/8/9/17/19/20/28
Use an app like LTE Discovery to see what band you're using in your most frequented places.

Make Honor 7 PLK-UL00 support more 4g band

Hello everyone
Can any one find a way to make PLK-UL00 suppout more 4g band?
I'm actuelle in France and i can't get 4g signal with PLK-UL00
My operater is free mobile
Thanks a lot
Where did you buy it ? And how long has it been since you have that issue ? I live in France as well, and I have 4G (with Free). But there is an issue with Free for the last 3 days so it may be Free-related and not H7-related.

According to all accessible information Free Mobile operates only on LTE 2.6GHz. And PLK-UL00 doesn't support 2.6GHz, it works in Europe only on 1.8GHz.
It seems that this phone supports only Bouygues LTE in France and even that partially.
The Honor7 from Three UK supports bands 1,3,7, 8,20 LTE.
Tested sim cards on O2, Only, SFR, Orange, Tmobile and of cause 3 In store

International Stravel Support

Does anyone have experience taking the Verizon Galaxy S7 Edge overseas? Or know what international frequency bands it supports?
I'll be traveling soon to Europe (France, Switzerland, Germany). Curious if I'll be able to get LTE with local carriers there.
Thanks!

Dumb suggestions but:
Make sure your in global mode in settings > mobile networks > network mode.
Make sure your APN is correct for your SIM (I assume your using a local Sim).
Make sure to turn off advanced calling so the phone isn't stuck to stay on LTE during calls.

Global LTE band chart for the S7 Edge

Thanks! I did some digging and found and charted the specs for the Verizon, AT&T, and France S7 Edge models. You can see the details in the attached Excel spreadsheet. Hope this is helpful for you guys planning a trip or traveling. Got the French specs from the Samsung France website.
The Verizon model is missing a few LTE bands that the French model has: 1, 12, 17, 25, 26, 28
I found this detailed LTE chart for France. Looks France mainly uses 3, 7, 20, and 28 -- so the Verizon model covers three of the four.
There's also this global LTE band chart, and this LTE chart for Europe.
Quick LTE band primer based on what I've learned:
LTE bands all have a number and a corresponding frequency. This list seems standardized worldwide. So for example band 1 is 2100, band 2 is 1900. In my Excel those are represented as B1(2100) and B2(1900). On the different web pages I link to, sometimes they refer to the bands just by number, and sometimes just by frequency, and sometimes both. But be careful, there are multiple bands with the same frequency number, but they are not the same -- for example both band 2 and band 25 are 1900.
I hope this helps others with your travels!
Anyone who has used the S7 in other countries (either Verizon SIM or a local carrier SIM) please do share your experience!
P.S. For those of you like me who have a spouse with an iPhone (ugh), Apple has a helpful chart of their LTE compatibility.
