Hello,
I am using Redmi Note 3 SD version. I have used it since December 2016 with Jio(India)
It worked perfectly. Now after using it with Vodafone 4G , i faced issue with 4G and most of the time got 3G network which i thought was restricted to that carrier.
Now i switched back to Jio and 4G drops constantly in some areas where other phones work perfectly with same SIM
I unlocked Bootloader flashed old MIUI version and rooted my phone
I installed Network Guru in that
for Band 40(2300) it drops constantly with LTE RACH being Radio Link Failure and Failure at MSG2
When i lock it to BAND 5(850) it works perfectly. Can someone help me find out whats the issue? I would love to get back to using all the bands as this may prevent me from using network in some areas

My kenzo has the same issue with China Mobile(China).
Failure at msg2 for band 38, band 40 and band 41.
Currently, I lock it down to band 39 to get it work.
I tried another SIM card by China Unicom doesn't have this problem, it uses band 3 and works fine.
Tried to flash the original ROM and modify the NV with QTSP but didn't work.

I think its an hardware issue, replacing the motherboard might be the only way

Hi, the Note 3 Pro is stating the following frequencies for LTE 1800/2100/2600MHz and according to Google, Koodo is 1700/2100 MHz (AWS). Only 1 of the frequency matches, does that mean that the signal reception will be bad or not working at all? Is there a way to fix this?
Thank you!
The Note 3 Pro works perfectly fine on Koodo. I didn't have to config anything with the APN and such, just popped my sim card in slot 1. Haven't had any issues.
IT may work as you say, your more than likely speaking of 3G. . . What about 4G LTE ?
I know that Fido/Rogers are not using the same frequencies so it's not exactly an answer to your question but with Fido I got strong LTE signal everywhere I went so far.

There are three versions, the one you found, there is one with band 4 (1700), and Kate special edition with band 4 and a bunch of others.
You need the one with band 4 or Kate or Lte will be really spotty and won't work indoors at all.
I have the the one with band 4 and LTE works really well with Bell. All big 3 carriers use band 4 (1700) Lte.

I have the Kenzo model from Geekbuying. I get LTE on Koodo.

Are you a new or existing virgin mobile user. If existing did you get a new SIM from Virgin? As they need to issue a new one to you if you want to go 4G.

There was also something else I read (virgin user here to - currently non 4G) about having to wait until your next billing cycle until you can begin using 4G services. Annoying and I've seen lots of people complaining as they have to wait to their refresh date which could be anywhere up to a few weeks.
Probably stating the obvious but have you selected the LTE option under (preferred network type) mobile network settings?
Sent from my Redmi Note 4 using Tapatalk
Yep LTE set as preferred
Also I ordered the sim before my last billing date. The sim turned up about a week after the billing date.
Maybe the next billing date?

Possibly yeah, that's the only thing I can think off. Worth it to keep trying the odd reboot or switching in and out of aeroplane mode in case that helps it kick in.

Check what LTE bands Virgin uses and see if the Redmi Note 4 is compatible with said bands. I'm on T-Mobile and the Note 4 does not support it's LTE.

They use EE's, who use bands *3(1800) and 7(2600), so definitely compatible.

Have u checked to use another provider?
i have a similar issue, not all providers that have these bands listed use them in all locations, i am with Rogers in canada who does have band 7, which this phone has, but they only have it in certain areas, not the full coverage, so i sit on 3g a lot.
Check this site, i shows that your provider also has limited coverage on the available bands. willmyphonework.net
I have the same issue. I'm with Three and it keeps dropping to H+ far too regularly.
Had this sim for a while and worked perfectly well on my Jiayu S3.

It happens to me. What I found from google, it said Note 4 Hardware supports Band 4 and Band 7, but the miui 8 locks them.
Still looking for a way to open those bands.

Band 7 should be supported and usable but I doubt the hardware supports band 4.
You should have gotten the Redmi Note 3 instead, the Chinese version supports band 4, 7 and 40 out of the bands used in Canada, and the Special Edition ("international version") supports bands 2, 4, 7 and 40. The Chinese model also supports 3G on band 4 (1700/AWS).

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.

Hi All, i am from india and using Jio sim( 4G provider in Band 3, 5, 40). In stock rom I can see the sim can able to connect All bands,. But in all AOSP based roms the sim is not able to connect to Band 40( Always very less signal). Can anybody explain this? I tried Network signal guru App to lock the sim to band 40 only,. But the band 40 itself not listing in the app,. I can able to select band(3 or 5).
Please advise is there anybody using Band 40 in AOSP roms?
Wondering if anyone else has network issues with their BC72 in Canada. I'm on the fido network which means no 5g.
The phone works absolutely fine on wifi, but throw in a sim card and the problems are as follows:
Phone randomly freezes with the screen off, needing a manual reboot.
Camera fails to start half the time
Calls drop, texts fail to send
Apps take ages to open or freeze during use
All of this is intermittent so it can work fine for hours then become basically unusable.
I know this is the Chinese version so I'm wondering if flashing the ROM would help? Thanks in advance

according to the fido forums
GSM ~ EDGE (2G) ~ on band 5 (850MHz).
UMTS or WCDMA ~ HSPA (3G) / HSPA+ (4G) ~ on band 5 (850 MHz).
To access LTE, the device must be compatible with one or more of the following:
700 MHz on Band 12;
850MHz on Band 5;
1900 MHz on Band 2, Band 25;
1700/2100 MHz on Band 4, Band 66;
2600 MHz on Band 7.
Fido doesn't offer 5G
I’ve been using this phone in Canada for years but I don’t have these issues. The CN firmware has different Google services including the phone and text app and also the camera app. Also it’s always trying to connect to servers in China but it’s extremely slo in Canada. You can flash a TW firmware and I’ll be good. Flashing stock firmware doesn’t require root or unlocking. Also I was with Fido before and the LTE bands seemed okay since I never experienced a signal issue.
