My POCO F3 8GB/256GB suddenly not letting me call anyone (Says mobile network not available) or pick up any calls but mobile network and texting is working completely fine. I've rebooted the phone multiple times, disabled volte, reinstalled google carrier services and still nothing so I had no choice but to factory reset the phone but that didn't work too. Currently using MIUI 13.0.9 and hoping there's a way to fix this asap.

Use miui flash tool to reset your phone to he miui version it came from. If it does ot work then, it's a hardware problem.

I'll try doing the MIUI Flash method. I hope it's not a hardware problem because everything was working fine and I only realised few days ago it started to not work
Check with other sim. If problem remains check different network modes 2G/3G/LTE.

So I've tried using 2 different sim cards (One of them being the same carrier as the sim that's not letting me make or receive calls on the F3) and so far those sims are working fine with the phone . Also tried putting the not "working" sim on other devices and it seems to work fine so I'm not really sure what's the problem here. As soon as I put the sim card back on the F3 it works for a moment then completely stops letting me call and receive calls.
Try changing network modes.

That method also didn't work
did you try downgrading to 13.0.8.0 fw? could be a defective modem driver
Try manual network selection. If fails probably hardware.

I'm getting Location unavailable too on Firmware 13.0.9, revert back to Firmware 13.0.8, and the location is okay again. Maybe you can revert to Firmware 13.0.8, don't think too far first.
Try to enable volte and vowifi. I had the same problem to my device and it is working

Hello, thanks to my carelessness, I think I broke my dual sim functionality.
What I was doing was messing around in the network settings in Engineer mode that can be accessed using *#36446337#. And all of a sudden, both sims stopped working. After a lot of messing around with the RAT settings, I could get one of the sims working. After selection sim1 or sim2 in the options and changing the RAT settings for that sim, I can get said sim to work, but it breaks the other. No matter what I do, I can't get both working again. This was on Open Beta 9.
What I've tried doing since then:
1- Factory reset
2- Flashing another ROM (Lineage)
3- Flashing latest 4.0.4 firmware
nothing seems to get both sims to work. Always just 1 sim working. Does anyone have any thoughts what I could try?

Just do a full wipe with the unbrick tool and everything will be back to normal.
I have the same problem after I mess with the engineer mode.
Tried everything and still unsolved.
Try installing the modem or firmware of previous oxygen OS builds then updating the oxygen os

Yes, I tried the unbrick tool but it's still the same. It seems to me that the GSM/WCDMA band of the phone is broken. When put two LTE card into the phone, both can work under LTE band.

Installed the OOS3.0 and then updated to OOS4.0. Dual sim function won't work on both OS.
Flashing modem usually can solve signal lost on Samsung, but it seems that it won't work on Oneplus.

Well you just said you are a noob.. No problem but really dialing a number isn't going to break anything in your phone.. Wipe all partitions then Flash OOS 4.0.2 and o guarantee it will work, this is pure something in software level.
I have successfully fix the problem according to a post at Oneplus Community in China. Just Flash Official H2OS 2.5 (Android 6.0.1 ). Go to engineer mode. Choose Network Set -- Band mode --Hardware Default (Foreign) to fix the problem.
P.S. If you are in mainland China. Pls choose Hardware Default(China). Else choose (Foreign)

I am using Z2 plus from about 15 months with Jio sim with VOLTE enabled without any issues. Suddenly VOLTE has stopped working. Toggled VOLTE, toggled data/airplane mode, tried multiple restarts but VOLTE is not working. Data (internet) is working w/o any issue but I can't make/receive calls as VOLTE is not working. Appreciate if somebody can offer any solutions.
Im also facing the same issue from today(15/8/2018 IND Independence day).
I flashed tons of ROMs and still the problem persists.
Please find a FIX for this.
It has happened many times to me. Try these steps :
1. Eject the SIM tray
2. Interchange the SIMs
3. Let the network bars appear.
4. Turn off the phone
5. Interchange the SIMs again
6. Start the phone
It works :fingers-crossed:

Thanks madhurjajoo but this doesn't work for me. I also suggest that you try toggling airplane mode on/off next time you face the issue. So far that's solution that worked for me when VOLTE stops working but nothing working this time.

I have faced this problem for a lot of time. In the end, i installed stock rom again via mi flash tool - Zui v2.5 (you will easily get the link in xda). Once i got HD symbol and tested a call, i clean wiped the phone and installed custom rom again which supported volte. But before starting the rom for first time, i flashed baseband v1.7 (which i think is of zui 3.5). I got volte after 5-6 months and I'm happy.... My current rom AospExtended Oreo based doesn't have great battery backup but atleast I'm content with VoLTE. Hope it helps
Hello Guys
With unlocked bootloader, I have been to China and used local sim over there.
Now I am back to India and none of Indian SIM cards are getting detected by phone.
I tried all possible options, did reset..downgraded to Oreo also..but no luck. What ever sim card I try, it's not getting detected.
In device info, it's showing mobile radio is off, tried switching on several times..but no luck.
Can someone pls help me ASAP.
Regards
Pavan
Try resetting network settings or hard reset the device and also try flashing factory image if previous doesn't work.
If your bootloader is locked then try reaching customer support. Else, you can try restoring some efs/modem backup using twrp.
Do you get any notification when you insert the sim tray?
I may be wrong just sharing my 2 cents.
Same problem here (or similar, at least).
My 5z recognized the SIM card on both slots, but no signal.
Tried all of the four carriers from Brazil, tried a hard reset, tried the Android Q beta, switched back to Pie, nothing works.
BTW, I've seen three devices with similar problems recently. One Samsung, and two Motorolas. All of them was updated to Pie. Could be some update bug?
My problem was fixed after the May update that was released a few days ago.
Everything working fine, 4G, LTE, etc.

Hello! I updated my phone to MIUI Global 13.0.7 Stable (SKHINXM) and suddenly my phone has no service. The sim card is fine and working on other phones like it was before the update. Really unable to fix this issue. If it helps, in the testing window the 'Mobile Radio Power' is toggled off and however many times I try to switch it on, it automatically switches off. Please help! Thanks

13.0.7 Stable (SKHINXM) is a stable beta.
Try to reset the phone or if your bootloader is unlocked flash with this tool

Okay thank you! Will try it in a few days time once I am able to give it the time needed.
It is happening to me too, I'm on stock 13.0.4 SKHMIXM, bootloader locked, it happened in 13.0.3 too. Sometimes, I see I have no services, no data, no GPS. But WiFi works great, so if I'm in house I don't always see it, but it means I cannot receive call!!!
I tried to enable/disable sim/data/location/airplane/etc nothing works.
Only way to re-make it works is to reboot the phone, and after 2 or 3 weeks it will happen again, this is the price to pay to have cheap chinese phone...
Try booting into Android with Safe Mode. (and disable Airplane Mode if enabled)
Power + Volume Up > Safe Mode
Or try this:
Settings > Updater > Tap on the "13" several times, this will enable additional Updater-features. Download the latest package and install it.
My guess is that your update may have been corrupt.
Other than that.. Factory Reset or connecting phone to PC and flashing ROM using Fastboot & Mi Flash or Terminal.
I've 13.0.7 and everything's flawless.
So the Xiaomi service center told me that it is possibly a motherboard issue. How can a software update suddenly awaken a hardware issue?
So I had not unlocked my bootloader via my Mi account and it needs mobile data for the same and hence I am unable to flash it since my network is still unavailable even after a factory reset. Any other way I can flash my phone with an older version of MIUI or I will have to submit my phone to the service center?

Same issue i am facing after MIUI updation for 13.0.3.0 SJCINXM ... suddenly all networks are vanished ... if i do manual search for networks then i get a message 'Couldn't search for mobile networks' . Voice call is only possible if wifi is enabled.. This is really a horrible experience and i am unable to find out a way to get rid of this situation.. I am using Redmi 9 Prime handset .. Before this update everything was surperb and flawless.
It is still happening with the latest Android 13 and MIUI14, it's frustrating... sometimes when the phone switch wifi/lte/wifi/lte/etc when you go outside, the modem crashes, it internally bootloop and the phone becomes warm and can lose 25% battery in like 15 minutes. Only way is to reboot the phone.
I had a similar problem. Were you able to solve it?
Hello everyone. I have a realme GT Master Edition (RMX3360).
The problem I am facing is that, SIM network does not work. SIM is recognised but it won't connect to any network, so basically I cannot use the SIM card even though the phone knows what SIM is this.
I did try:
Factory reset.
Use Force LTE app to access phone information and switch bands (I noticed radio toggle is switched off, I tried turning it on but it won't).
Unlock bootloader, just to increase my chances.
Flash only modem/hlos/... related partitions. Did not work (phone bricked).
Flash OFP firmware. Did not work.
Flash EDL firmware (C.09), which I am currently using. Still same problem.
Different SIM cards.
My IMEI is fine, it is recognised. My baseband version is 4. I did search for the issue in realme community, and it seems quite popular as a lot of people suffer from the same issue on different models.
I live in Sudan, we got no 5G, no VoLTE or whatever. Could you help me please?
I have similar problem after reboot .I can't connect to network or it tooks long time . What helps me is switching to airplane mode.

Thanks for the suggestion. I did install RMX3363 EU ROM from EDL, it booted fine but the phone still won't connect to any SIM network.
I will also try Russia ROM to see if it would make any difference.
Update:
I did flash Russian ROM from EDL, still does not work. Modem version is also still 4. I will try Chinese ROM next.
Try Latam version this what they put in middle east but so far i think its hardware issue did u try the sim card on another phone? Did you try another sim provider on your phone ? Sometimes if the sim card too old it wont work

That LATAM version is 18 Gigabytes haha. It'd take a few days to download.
I came to think it might be related to modem images as it showed the same version repeatedly on both RUI 2 & 3. So I'll try different modem images.
Also I'll try custom ROMs and GSIs. If it failed I'll return the device as a very last resort.
Update:
I tried latest Official ProjectElixir till date, still same problem.
Update 2:
I gave up the device and replaced it with another one under warranty. I will not buy another realme phone anytime soon.

I have a Xiaomi device too. The new virtual proximity sensor depends on hand movement to function. I don't use MIUI, but it is very fine at all situations.
Also I got a (256/8) GT Master replacement which is surprisingly working fine; being the same RMX3360.

It was already updated to F.03, I heard there was screen flickering or something but I didn't notice any so far.
But I did notice the battery was draining fast on mobile data. Really fast.
Besides, I can always lean on post-market development.
