Hi, I bought a Redmi 4X some years ago!
After using 2 or 3 months, the phone (calls) stops working!
I changed the SIM card by a new and working one!
The smartphone works well with wireless connection, but the "radio" phone is dead! It's not able make/receive any calls or SMS/MMS messages!
I take it to a store and was told me that the only solution is change all the board of the smartphone!
This is not a solution, because the price is almost the same of a new smartphone!
There is any solution for this?
Thank you for your help!

Hi chaps, I have tried searching across the internet with no luck, here's the deal.
I bought this p1000 galaxy tab some days ago from a guy on a forum. tried it thoroughly before paying, inserted my phone SIM, got a phone call, sms, 3G internet, wifi, all working flawless. I used it for some days wi-fi only waiting for my new tablet SIM to be ready.
Monday, I receive the SIM but it still had to be activated. I just kept it in the tablet waiting for it to be OK. Zero problems, just the usual "no service" message like you would expect from a sim that's yet to activate
This morning I finally get the SIM activated, but as soon as I try sending a text or something, the tablet just shuts down. After that, no way trying to boot it up again: it reaches the Samsung logo, then bye bye. If you remove the SIM from the tray it magically comes back to life.
I already tried the usual stuff, like hard resetting and like, cleaning the SIM or something. I also tried with another carrier sim and I get the same behavior. I'm starting to believe that there is some hardware fault with the SIM reader, but I thought I'd try to get some hints from here before calling Sammy's assistance. Also the weirdest part is that it worked some days ago!
If anyone has any idea/experience to share, I'd love to hear from you mates. thanks in advance!
(oh and btw I know how to hit a thanks button)
I'll update the post with further intel, maybe it will help someone down the road.
The tablet does not like freshly activated SIMs. I know it sounds crazy but that's where we are at. We have tried like 4 different SIM cards from different operators, all work flawlessly; The SIM card of the above NOW works flawlessly as well, it just needed a couple days to settle down. I have no idea if this is a software bug, a hardware fault or some strange network settings from my carrier, but the problem seems to be solved for now. Luckily i didn't send it in for repairs!
Hello All,
I purchased a Samsung Focus - i917 to use while over in Spain this year. When I first got here, carrier unlocked the phone, I bought a Yoigo SIM card, inserted it and imput the APN settings for their network. My WhatsApp worked fine, but nothing else worked, which I was fine with for the most part seeing as my social life survived just fine only using the WhatsApp. That was the first month. The second month, I started having problems with the Whatsapp, and I would need to shut down the phone once or twice a week to get the data flowing to that application again. Then at the start of the 3rd month, it stopped working completely, and I haven't been able to get it to work since. I it works fine with WiFi, just not with data. I even switched to Orange a couple months ago to see if that would have any effect, but to no avail. I am on the verge of buying a new phone, but thought i would post one last ditch effort here with you all in the hopes that someone might have an idea/know how to fix this problem.
I was thinking of trying to do an interop unlock, but I'm pretty tech-less, so I could just follow directions, but I would have no idea where to go from there, or what I was actually doing, or how I would solve the data problem if I was successful.
Any help would be greatly appreciated. Thank you for your time.
I recently purchased a 2nd hand Galaxy S3. Put my GiffGaff sim in worked fine for 2 weeks.
Then one day i lost calls and texts with the Not Registered on Network message.
Got my friend to phone EE to check if it had been blocked, no problems with the imei and 2 days later it started working again. And that was after rooting putting custom recovery etc.
1 week later same probloem, not my sim as it works in other phones and same problems with otyher sims in the S3.
It;s been a week now. Samsung support advised me to go to Samsung engineer shop for the issue to be diagnosed.
Mobile data still works.
Can someone please help.
Hi dear friends,
I have a Chinese K20 Pro with unlcoked bootloader and running india firmware 10.3.5.0
Previously I had Huawei Mate 10 Pro working with VoLte flawlessly. but my K20 Pro VoLte option was not present in the menu so i searched a little bit and find following code to re enable the option *#*#86583#*#*
After enabling the volte, to be sure that if it really works, i tested avalablity of internet data when i was talking to someone and it was ok.
But from 2 days ago there were several(if not all the time) that when i got a call or when i call someone just seconds after connecting the connection dropped 4g volte icon disappears and mobile signals goes grey with cross icon on it and after just a seconds it turned on again, it was like i pulled out the sim and insert it again.
I have not any problem if i turn off volte option and i was almost sure that the problem is some incompability between my phone and operator volte but i tried something else too, i switched the sim from sim1 to sim2 and with volte on i don't have any problem so i got confused do i have hardware problem?
Any idea?
Same on me, Telenor Bulgaria.

So it worked for you before but now you have the same problem as me? Or you always have the problem?
Also did you have the same situation with the sim slots?(one is ok another not ok)
Yes, it's working fine last week. I will try swaping cards. Maybe it's a software related, updated to last beta from xiaomi.eu on saturday. Problem arrived after that.

Please swap the sim cards and test, it is almost 2 days that volte on sim 2 is working ok.
Edit 1: it is almost 4 days that i use my phone with volte ON using sim 2 no call drop no problem, can anybody confirm the same behaviour?
It was same with me, also Telenor Bulgaria.
I switched to sim 2 after reading here a few days ago and the problem seems to be resolved.
Before I had to restart the phone in about 2 days, because I just stopped hearing the person who calls me. Or switch to 3G. But to use VoLte again I had to restart. It just happened every other day...
Now everything seems to be fine... with that problem.
I still have the problem of not being able to use the Google Assistant to unlock my phone and can't turn on location history on Google maps.
I guess it's because of the Chinese ROM.
Anyway thanks for showing me a way to use VoLte less struggling

Glad that it helped, but it is strange problem
By the way i didn't use chinese rom, i am using indian rom which is almost the same as global rom but the device by default was from china and was running chinese rom, my theory is that devices came from china have some incompability with the bands or volte with other countries...
Volte disappearing and data & voice calls get disconnected.
I bought my k20 pro last month & last week all of a sudden volte got disconnected & appeared again.
Then after few moments my friend called me and all of a sudden call ended & I saw No network on the screen & after a few seconds volte was enabled again automatically.
At , First I thought it was just data or APN problem.
Then the things got worse when I was playing PUBG game and volte disappeared again and same thing happened again and again every 6 to 7 minutes .
I am frustrated of this , can you get me out of this mess , can you tell me what should I do to solve this issue
Thank you

It seems nothing we can do about this, just disabling volte solves the problem.
My guess is that K20 Pro modem is optimized for China's cellphone towers so volte is not quite compatible with other countries. it is just my guess.
Hello,
So my original note 8 was N950F 256GB Dual SIM bought in 2017. It kept on working fine, until recently it started giving the problems in mentioned order
a. excessive battery drain
b. not being able to charge wired or wirelessly
c. complete blackout.
I went for a lookout of a replacement 256GB , and was able to find one on AliExpress, risky as it always is, i took my bets to order one after some correspondence from the seller who seemed legit and helpful.
Fast forward 22 days, I got the motherboard, installed in my existing body and housing, and voila it turned on and apparently seemed to be working fine. However i came to conclusion that it was originally a N950N (maybe Korea Dual SIM) motherboard which was flashed with the firmware/CSC/baseband for UAE reigon , maybe it was done by the seller knowing my location for ordering and the usage reigon. KNOX status was tipped as well, but it is not rooted as of now (maybe reverted to stock) , so all root sensitve applications (banking , netflix etc) do work as well.
The problem is, though everything works as intended. I am unable to place and receive voice calls reliably. Most of the time the outgoing call never gets placed on the network and drops after waiting for 8-10 seconds, and the incoming callers inform me that my mobile was out of reach for them to ring me.
I suspect it may have to do with the correct baseband not being compatible with local service providers.
Seeking expert help out here for the guidance , download location and the right combination of the firmware components to be used to bring the phone back to a reliable voice calling status to be used in KSA region
All help is much appreciated.
