few days before i rooted my redmi note 4 , when i reboot the phone i found that jio 4g sim is showing NO SERVICE. i replaced with new jio sim but same problem, even i did all the settings correctly. then i tried airtel 2g/3g it worked fine. i flashed my phone many times with all global roms of different versions, also i flash modem but still nothing happened. so i need some help, please tell me what should i do now?????
Well if you have tried a different SIM from Jio itself and different roms, it should mean that there's probably no 4G connection available where you are.
I have a RN4 (Germany) and I have zero issues with connecting to 4G networks here, even from the prepaid SIMs.

Hi to all.
I put Cofface's cyano into my Redmi 3 a week ago and it worked fine except for the network signal that seemed to me to be weaker than on stable or dev miui rom. Yesterday I don't know what i did, i just switched the network type from the services menu (*#*#4636#*#*) to see the signal strenght of 2g/3g/4g and after doing that, the phone stopped to take signal with my SIM in any network type. So i switched back through MiFlash (and selected flash all option), to the Dev and also to the stable rom, but now I just have 4G working.
I tried to put again CM and i get no signal in every network type, even trying to restore a nandroid backup that i made when the phone worked. I also tried to flash through fastboot the NON-HSLO.bin took from developer rom, but nothing changed. What could it be? Where I live the 4G is not everywhere so most of the time I'll be without signal and it would be really frustrating.
I tried my sim in a Samsung phone and it takes both 2g/3g (the phone doesn't have 4g) , but trying another sim in my phone (of the same carrier) gives me the same result of above : only 4g . While on CM that sim could connect (only 4g) but mine not.
Please help me! :crying:
sorry if i didn't explain myself well, but I'm not english
EDIT: with the 4G i can only surf on the net but i can't make or receive phone calls. I'm giving up on this phone
EDIT2: following some guides I erased modemst1 and modemst2 but now I'm unable to get IMEI and I have unknown baseband
I have the same problem as you (almost)
http://forum.xda-developers.com/redmi-3/help/cellular-network-redmi-3-t3370459
I also have poor reception and can't make any call or receive them on any band 2g/3g/4g and i have this problem since I received the phone.
Did you fix your problem??
I have the same problem of very bad cellular signals.
with the same carrier, when other phones 2 samsung, 1 chinese (cheap unbranded), one very old nokia all have good reception, xiaomi redmi 3 pro is inaccessible from other phones.
today I'll try to install some signal booster apps from thestreet.com/story/11733410/1/7-apps-that-improve-smartphone-reception.html hopping for the best.
if anyone find any solution please update
Hello, this is my first post on the forums here.
Iv'e purchased a Xiaomi Redmi 3 last week. It turned on fine and after the first turnoff-turn on it simply didn't turn on again and was stuck on the mi logo.
Iv'e downloaded the latest stable chinese rom and flashed using miflash and the phone started working properly again.
The problem is I do not have a cellular signal. It's either non existent (empty bars marked with 'x'), empty bars or one or two bars at most. Even when there are bars I cannot receive or make any calls (when i call the phone it just rings and the nothing happens).
The sim card itself is new (micro), the phone is new. I tried contacting the cellular company and they said everything is fine on their side, also iv'e tried the sim card on another device and it worked. I tried fiddling with different settings like changing from preferred lte to prefer 3g, adding new vpn, changing the sim card settings through the phone from WCDMA, only LTE so on and so forth and nothing worked.
Iv'e read around the forums here about the whole bootloader unlock, rooting, dev roms. I'm a newbie when it comes to these things and don't know weather I should do there and if it would help my problem.
Oh and last thing, I also verified that the device 3g/4g networks are compatible with the cellular companies in my country (same ones).
Thanks in advance,
Maybe there's a problem with ur set. I didn't root nor unlock the bootloader and reception has been fine for me from the start.

So you think it might be a faulty phone?
EDIT: I don't know if this helps or connected to my issue but i have this notification at the top saying "your SIM card isn't activated". I can't link to the pic since i'm a new user.
No one knows how to fix my problem?
I've got a similar problem I think.
I searched until I found that while flashing my IMEIs got lost and so the phone can't register to the networks.
Now I continue searching how to restore the IMEIs...

Hi there i bought my note 3 pro with some vendor rom 7.1.99.99 and it ony worked 2g in both sim slots. Tried already flashing all kinds of ROMs tricks using qpst etc the outcome is the same. Do you have any more ideas to recovery at least 3g?

What is your phone carrier/provider, I would check what your provider supports in terms of Network Bands/ Frequencies.
You may likely need to switch to another phone carrier to have it working on 3G or better yet 4G.
If you do have the supported Bands/ Frequencies, I can help you with setting them to work with GSM network, LTE network, or setting between the two. (You just got to provide what country you use your phone if you are unable to provide your phone provider or simply do not know).
OK, from the day I bought the phone, I was not able to connect to any 4G LTE network.
I tried MIUI (obviously), CM13, Slim, AOSP, etc and was not able to connect to 4G network.
I even used this method to fix LTE issues: Link.
I am currently testing all the ROMs available. Flashed about 8 different ROMs today itself.
Any fixes/workarounds?
Thank you!:highfive:
I have an unlocked Lenovo Golden Warrior Note 8/A936 2 gb ram dual sim phone. Its also rooted. In my country there are 2 network providers. I have a SIM for both. The phone recognizes both of the sim cards and even labels them by their network name but only picks up the service for one of the network providers. Ive made sure both sims are good. They both work fine in my Samsung Galaxy Note 4. Trying to figure out what could be wrong with the Lenovo as it won't pick up any service for that SIM card.
Ive tried:
both sim slots and still only one recognized.
removing the working one and the other still wont find service
Factory resetting
Manually/Automatically finding the network. Manual search doesnt find the ine i want to find
Switching from 2g,3g,4g preferred types
Any idea what could be wrong?
wrong lte/4g channel
Maybe your provider uses a for the handy not usable channel and the sim is a lte/4g only! So the device doesn'T recognize the sim, Iguess. I'm sorry, bad luck
