Dual VoLTE on Redmi Note 3 - Xiaomi Redmi Note 3 Questions & Answers

I know that when I put one sim in 4G, the other sim is automatically locked down to 3G. So I can only use one sim on VoLTE. Since both sim supports 4G, is there a way that could possibly force 4G or VoLTE on both sim?
Thanks in advance. Currently running Nitrogen OS 8.1.0 on Redmi Note 3.

asking tooo much tech was not available when this phone was released and its a hardware thing

At least try to google ;_;

Oh I tried. And the results weren't positive. And I didn't know that it is a hardware thing...

Possible flash Miui 9 port it supports Dual 4G and Dual VoLTE. I have seen that in their changeling however I have not tested it personally.

Does the LG G5 H860 Dual Sim support 4G and 3G simultaneously?

Hi everyone,
I'm quite interested in this phone. Does anyone know if the H860 Dual Sim phone supports both 4G and 3G simultaneously?
Both 4G on Sim 1 and 3G on Sim 2 at the same time, not 4G and 2G as in most other dual sim phones.
Thanks
4G and 2G

Hi,
Unfortunately 4G/2G or 2G/4G and there is on other option. As far as I know only Mi5 can work eg. 4G/3G or 3G/4G. I have got both of them so this info is true and confirmed.
Regards
Thanks to you both. That's really disappointing considering the phone has a Snapdragon 820 and other phones with this support 4G and 3G. Is there any custom Roms that support this functionality?

Unfortunately at the moment its not possible root LG H860N so you can not install alternative software. Even if, you still will have 4G/2G or 2G/4G because developer do not touch radio module. This a reason I want to get rid of it.
BTW The mobile is really good

First sim slot 4G problem with network providers other than jio

Hi friends I'm facing a weird problem. My first sim slot doesn't catch 4g signal for any sim except jio4g but the same sims work fine with 4g on second sim slot. What can i do regarding this problem ?? Please help me

Xiaomi and USA use....?

Hey everyone!
Currently a user of an RR rooted oneplus 3. Love the phone but I keep hearing good things about Xiaomi.
I must admit I'm curious, especially with the Mi Mix 2 coming out. How are Xiaomi phones on US cell networks? I would mainly be using AT & T. I have no problem putting custom roms etc on my phones so that's not an issue.
I just wouldnt want to be stuck with a phone that had bad 4G/LTE support.
Pros and cons of going with a Xiaomi phone vs say the one plus 5, or a true US supported phone like the LG V30 or upcoming pixel XL2 or even the asus zenphone 4 pro?
Curious to see what everyone has to say .

I'm using Redmi note 4 global Version in USA on T-Mobile. You just need to do a little research on what frequency at&t uses. Or what bands they use. For me I'm only getting 1 LTE band supported which is band 4. I get lte everywhere and it's fast. This is what at&t supports 17(700Mhz), Band 5(850Mhz), Band 2(1900Mhz), Band 4(1700/2100Mhz) currently. You can use this http://www.china-prices.com/phone/bands/7131/xiaomi-redmi-note-4-64gb to check compatibility with Chinese phones it's pretty accurate. So I just looked it up the global Version of Redmi note 4 you would get 2 LTE bands. Better than what I get. You can research other xiaomi phones as well.

Also switch service to mint sim for $25 a month with unlimited talk text and 10gb of data. Redmi note 4 global Version 3gb around $150 and the 4gb version around $200.
There are some xiaomi phones that support more bands but they do cost more. A unlocked phone in the USA you should be getting at least 3 LTE frequencies support. Like on T-Mobile there are 3 main bands. 2 4 and 12. 12 is for when your inside and it penetrates through buildings. At&t might have the same type of thing with 850mhz. Lower the frequency the farther it can travel.
Feel free to direct message me if you have more questions I've basically researched all available xiaomi phones. I can help you with compatibility
You don't have to worry about bands support, if it doesn't support bands on USA, You can unlock all bands on Mido, 1-41 bands can be unlocked

So basically as long as the soc's modem supports it then there are ways to unlock it. I am unfamiliar with Mido. What is that? I am going to be targeting a Snapdragon 835 phone here in the next month or two. Hopefully we will see on the 11th the mi mix 2 getting that Soc.

I'm not sure about the first line, but here on RN4 it can be unlocked with other version of RN4 who had All bands unlocked
Mido is code name for Redmi Note 4, every devices on Xiaomi have their own code name
I think yes it will be getting 835
I think it will be support for Mi Mix 2 on USA, i know someone who had mi6 basically had same soc, and he can used it in USA
Unlocking bands is not easy at all.. it's possible in theory, but it's extremely complicated and dangerous you can completely brick your phone.
Dont even consider this, i dont know what this guy above is talking about. Maybe he will present us unlocked all bands if this is so easy?

It's easy and it will not brick your phone, only signal loss and you can restore your backup if anything happened (signal loss)
I have the redmi note 4x international with snapdragon soc on cricket (att prepay service). I cant say about the mi max 2 but my device works great with att network. The phone came with the global rom installed and all I had to do was put a sim in it. Network was found, data worked, sms and mms both worked. Have had no issues with the phone on cricket/att.
Just like to follow up with my post. Did some digging and apparently mi mix 2 will be fully capable in the US as the mi mix 2 will ship with a global version that has Google play support. Very cool stuff if this article is to be believed. https://www.google.com/amp/s/www.fo...ix-2-was-built-with-the-u-s-audience-in-mind/

Make sure your sim is in Sim slot 1 which is the one that goes farthest inside phone that's the only one that works for LTE.
Looks like your carrier runs off the t mobile network. You have lte band 2 4 and 12. There are also multiple versions of redmi note 4. If you have redmi note 4 global version which runs the snapdragon processor you should be ok and getting LTE on band 4.
Also depending on what area you are in and the cell towers in your area you could be to far from LTE cell towers. Good luck
Go into sim apn settings there should be one already setup called fast t mobile. Because I'm pretty sure your on t mobile network you can select that and get LTE.

A good app from the play store is called LTE discovery it will tell you what band or frequency you are on I posted a couple screen shots on a different phone though running MIUI 8 but should be about the same. Also what plan are you on maybe you have used all your data? Also check with your carrier you might have to supply the IMEI number for them to activate it. Are you able to make calls?
Are you able to use the Sim in a different phone and LTE is fine?
Are you sure your not on redmi note 4x?

Does LTE actually continue to work for you after you make a voice call or when it otherwise switches to something other than LTE?
Because I'm on cricket as well and mine never goes back to LTE once it switches to H+. I've gotta go into preferred network and switch to to Prefer 3G and back to Prefer LTE to make it work again.
I've tried it with an AT&T prepaid sim as well. I've also done a factory reset, tried the nano sim in slot 2 and also in a micro sim adapter in slot 1. All with the same result. I've got good LTE signal on band 4 all over the place which works perfectly when it's connected. But if I make a phone call or walk into the center of home depot where the signal drops for even a second, it will go to H+ and literally never switch back.

oh OK. Im on 8.5.4.0. I should probably try 9, or Lineage soon.
I did actually witness this thing switch from H+ to LTE today, I couldn't believe my eyes. It was out in the middle of nowhere, and the LTE signal showed 1 bar, so apparently the H+ must have been even worse.
Guys H+ is fast too, I think it's like up to like 168mbps. Personally I have no problems with LTE but I prefer to use H+ because it's enough of speed for everything you could think of, obviously the signal is better then 4g and it's easier on battery.
Edit:
Actually it seems like H+ can be even faster then LTE.

S9+ Duos and Exynos - Dual Sim Dual VoLTE?

Is Galaxy S9+ Duos with Exynos SoC Dual Sim Dual VoLTE or 2nd Sim Card is 2G/3G only?
So, you will want to use two different SIMs and speak use VoLTE for both?
I think it's possible. I have never thought of it this way, but it should work (although I do not have any evidence to back it up)
Looks like SIM2 won't do LTE at all according to phonemore http://www.phonemore.com/samsung-galaxy-s9-plus-sm-g965fds/specs/3886
2G network SIM2: GSM 850/900/1800/1900

Galaxy S7 Edge, Galaxy S8+ Duos and Note 8 Duos (all with Exynos) have 2nd SIM 2G/3G capable. Why could S9+ have only 2G network on 2nd SIM, if older models have 2G/3G?
Galaxy S9+ Duos with Snapdragon SoC supports 4G and VoLTE on both simcards simultaneously. Is it the same with Exynos version?

Unfortunately non of this devices you mention supports 3G. You have to switch in settings in order to have suport 3G,4G for sim 2 and vice versa.
S8 Exynos (G950FD) supported VOLTE on both SIM but not simultaneously; the other SIM would no longer remain in VOLTE network mode if you selected that mode for one SIM.
It's a shame that below $100 xiaomi phones now support VOLTE simultaneously on both SIM but Samsung doesn't. I hope S9 series does.

Well, my pre-order is expected to be delivered by 17th March; I can test and let you know by then.
Will voLTE be enabled by default on unlocked phones? Or will I have to buy an operator modified ROM to have the option to use the VoLTE or Wifi calling services?
Thanks
Its Hybrid Dual-Standby config so unfortunately only 1 sim can be primary at 4G/VoLTE and other can be only 3G/2G at that time.
Yea, I've just got my S9+ Exynos and I can confirm: when 1st SIM card is connected to LTE/VoLTE service, the second SIM card is connected to 3G network
No Dual Sim Dual VoLTE.
Shame on you, Samsung. Half year old Huawei Mate 10 Pro is better choice.

Now we need to wait and see if the Snapdragon version can do it.
Another question, if you disable LTE on SIM 1, can SIM 2 then connect to LTE. Or do you have to swap the SIM cards over?

I second that.
I just received my S9+ (via renewal of my mobile contract) and received a dual sim one (check by inserting two sim cards, it does ask for both pins and let's me choose the sim card to use for calling), although it was never advertised as such.
However, it only shows LTE for the first one.
Considering that the dual-sim version is marketed as specific "Duos" devices, those might differ - but I wouldn't bet on it.

Need help with custom ROM on Galaxy S9+ Dual sim

Hello all,
Just bought a Samsung Galaxy S9+ dual sim (SM-G965F/DS) (G965FXXS7GSJ3) international model. Since I inserted my T-Mobile sim card I can only get the 4G signal and no LTE (also tried Verizon sim card and the same result). Speed test on 4G with a few different location (Northwest) and the result from 1.00mbps - 22 mbps max. I online chat with Samsung support and found out that USA don't support dual-sim and that's the reason I don't get the LTE service.
Is there a custom ROM or a way to flash my phone so that I can use the LTE service on my phone?
Thanks

Sorry but whoever told you they don't support DS sounds like BS to me, the carrier only see the phone signal, they don't know if it's coming from a single sim, dual sim or multi sim gateway device.
If you go into.....
settings --> connections --> mobile networks
and make sure both sims are set for LTE
1- 4G/LTE are the same. LTE/4G icon changes depending on ROM and carrier.
2- Samsung agent has no idea. It's a person on a generic building in India contracted by Samsung most probably.
If you own a dual sim s9+ you can get both modems/sims to work on 4G/LTE even at the same time.
If you see 4G you are working on LTE. Then what speed you get it depends on several factors, not just the phone or signal
