Few days back, i suddenly lost 4G and LTE on my Redmi Note 4 SD625. I have been using Airtel 4G sim for years but never had this problem. I am on stock MIUI 8.2.1 and not rooted.
I get only one IMEI number with *#06#. Is this normal?
Can sonebody help me with this issue? Thanks in advance

Hi guys,
I had purchased a Samsung galaxy s3 in India from ebay(big mistake) 2 years back. The mentioned model number of the mobile was GT-i9300 however I was not convinced that it was i9300 because it has got 2gb RAM. In About phone-->model it shows GT-19300 and even when the phone starts it shows GT-i9300. However in download mode (power + vol. down) it is mentioned to be model number SGH-T999. This is the most confusing this. (in binary counts it shows 1 too ). But in rootchecker it shows unrooted device. So I decided not to root the phone has it may brick it. Its on android 4.1.1 and when i try to update via OTA it shows "Your device has been modified. Cannot update"
I didn't much inquire that time since the phone was functioning very well and had no problem. But now when i insert 4g sim (Airtel 4g) the sim-card remains undetected. No problem with 2g/3g sims.
It would be really helpful if you all can assist me with the 4g sim issue.
Sounds like you bought a blacklisted phone with a cloned imei put into it so it could be activated... Google that model number that comes up and that'll show what phone that's really from
I just looked up sgh-t999....that's T-Mobile s3 someone flashed it and sold it to you man

Thanks for replying. The phone works absolutely flawless except about the new 4g sim. I was using old sim (3g) for past 2 years but recently bought a new 4g sim and phone does not read it It shows "Insert a sim-card" message only. Tried with other 4g sims too and doesn't work but other sim-cards are accepted. Anyway by which i can make the 4g sim readable by phone. I particularly don't want LTE to work .....just the sim should be readable by phone
4g cards are different. I9300 is not 4g.
I9305 is lte variant and accepts 4g cards afaik.

I know that 4g(LTE) will not work on the phone but the phone should still read the sim and at-least give 3g speed. I inquired this with service provider too taht my phone is not accepting card and even they wondered and said it should work and there is some defect with phone. I have got another s3 (gt19300) and that can read the card. I even tested on HTC ONE X (not a 4g phone) and still the card is read by the phone and gives 3g network.
4g cards can be accepted by 3g phones only that it wont give 4g speed otherwise it should work
OKay, I have now tried using my Tata Indicom CDMA sim (UIM) and the sim card works fine with the Phone.
I can make and recieve calls using the sim card. The only problem is, the Data won't work.
Things I have tried,
Keeping the APN blank,
Trying different APNs from Google results,
Copying the APN settings from my HTC one (which works with tata Indicom and data works fine)
I have also tried to check the hardware differences between the two phones and I found out that Redmi note 3 dsnt have ESN/MEID. And as per my knowledge, Tata Indicom uses MEID to authenticate data connection .
So is there any way to INSERT an MEID into the phone? Or trying some different ROM/Radio can be profitable for this subject?
P.S. I have read on different forums people claiming that their Relicance CDMA Sim data works fine.
Still no reply ?
I am also not able to get the data on Reliance CDMA. Plz help.

Go to settings/about phone
Click on internal storage 5 Times
Choose Phone Info 1
Go down and choose cell type
GSM/CDMA(auto)
I hope it works
It doesn't work
But I noticed one thing -
When I go to About phone -> 5 taps on Internal Memory -> Phone Information (of the slot where CDMA SIM is inserted)
I see that IMEI is 00000000 and
Phone number is 19869372 . . . . . . (1986 is pre-fixed to the mobile number. So the Phone number becomes 14 digit long)
Is there something wrong ? Because when I look at the same information on the GSM SIM, the phone number is regular 10 digit long.
Just buy it another CDMA phone. Because this GSM supported phone I think ?

Redmi note 4 how to work cdma sim please me reply
I've bought a european market ZE551ML and have it on the metro PCS network. Every APN I've tried both T-mobile and Metro fail to give me LTE or 4g. I had a previous ZE551ML that was on the same network that had no problem getting LTE. WW firmware phone with 4.21.40.352 MM Installed. The phones rooted and bootloader unlocked. I can get hspa+ but LTE is the problem . Attached are the Screenshots from my APN and phone settings as well as random network Data. Im a network engineer with alot of experience and I've tried everything I can without success a little help would be much appreciated and would using a custom ROM help in any way.
Unfortunately after adding over 7 tinypic URL images I had to delete them cause This is my first post which im sure would have helped alot.
Anyways thanks ahead of time.
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.
