Solution: Disable "Dual 4G" option in the "SIM Cards & Mobile networks" settings
Hello, good day!
tl;dr: Phone stuck to no cellular signal, until I reboot, restart mobile radio power, or turning on airplane mode for a short while when turning off again.
---------------------------------------------------
I recently bought this phone as an upgrade to my old one. I transferred my sim, and all seems to be working pretty well. I lived in an area with very poor signal reception, so overnight, the phone doesn't have any signal reception other than WiFi.
The problem is that it remains that way (stuck on 'no signal') if it cannot get any signal for an extended period. The problem persists even if I went to an area with good cellular reception even in the city.
The problem seems to fix itself when I placed the phone either by activating airplane mode for a minute, turn off "mobile radio power" then back on again, or reboot my phone but it starts to get annoying over time.
I tried changing the preferred network type to the one my old phone used (LTE/CDMA auto (PRL)) to fix it, but no luck.
Does anyone know a permanent solution to this?

Hello,
By default reset, you mean a factory reset or a SIM card reset?
Factory reset bro. But if you don't. Try yet this option of SIM reset try it

I tried the SIM Reset first and so far it is working perfectly but I need to monitor it first to check if the problem would persist in the long term.
Will update thread on the result.
================
Update: unfortunately, the SIM reset doesn't work. However, I tried swapping the SIM card to see if it makes any difference and surprisingly it did. I put in a SIM in slot 1 from a network with a good signal reception while my previous one on slot 2.
I would like to also note that the current SIM 1 has a successful Xiaomi activation & verified to use the chat features on the Messaging app while the old one does not.
All seems to work perfectly - but need further monitoring I can call it solved. Will update the thread on the result :good:
Update 2: The workaround above doesn't work. I sent to Xiaomi this issue.

My sim is in slot 1. still dropped calls. Seems like network disconnects and reconnects.
When call is dropped I immediately redial and sometimes no network.
Hi i have the same issue No signal, is there any tricks or tips or tools to fix this?

Unfortunately, the workaround I posted doesn't seem to work also when my current SIM 1 can't pickup signal for at least 2-3 hours.
Yes I also experienced drop calls most notably when the signal drops below 0 bars (not no signal with an "X").
I can't find a good rationale a factory reset would solve the problem since nothing on my phone (modified settings, modded, or downloaded apps) that can affect the cellular network. So, I won't be taking that road for now.
I already sent feedback on Xiaomi and advice me to send the log files *fingers crossed*
Any updates..?
My father is experiencing similar experience with calls hang and even bad call quality, while pocophone f1 on the same network works flawlessly.
Data problem
I have a problem with my RedMi Note 9 Pro, when I make a call on 4G Airtel network(at least 4 bars) the data connection drops to an average g of 1.2kbps.
I have used the same Sim in the same area in my previous phone the Honor 9 Lite but it doesn't face any problem. Whenever I get a call on that phone the 4G data speed increases.
On the RedMi note 9 pro the data gets completely disconnected and even after I cut the call the data remains disconnected for 2 minutes or so. After that I resumes back. It even gets lesser speeds that my previous phone.
Sometimes the data drops without any reason. It stays disconnected for a minute or so and then tries to connect back. It has got horrible ping.
Anyone facing the same issues?
Having the same issue here. I modified phone settings several times and try with another apps but nothing working so far
I MAY HAVE FINALLY FIGURED OUT A POSSIBLE SOLUTION!
Disable "Dual 4G" option in the settings.
No issue so far for 3 days now

I got a SGH T989 and got it unlocked for use in India..worked great for 2 months and then i rooted,flashed AOKP jellybean using CWM....after that, worked great for 1 month... Now the problem is that.....
My phone shows full signal and in the "about phone" menu,the signal strength is -100dBm BUT i cannot make calls and i'm out of coverage area for others.. The weird thing is that this happens only at certain spots (unfortunately, my workplace)...the device works just fine in other places...i ruled out a network issue coz my sim is good in other phones at the problem zones.
I tried another network's sim and it had call drop issues....the call would get disconnected after a few minutes and the duration of the call wasn't constant....this was also when the phone showed signal strength of around -100dBm. I had used this network before and it was working good with the phone..
I tried a master reset, complete system format in CWM recovery, reverted back to stock rom using odin, changed radios (UVLE1,UVLH1 and UVLI1)....nothing has worked so far.
There was no external injury or water damage to the phone, i didn't install any app outside of the play store and i use genuine charger for my phone.
I love my phone too much to let go....please gimme a solution
Thanks!!
Hello all,
I am having an intermittent but a strange signal problem with my wife's OnePlus X and I suspect that this is some sort of software issue with the modem firmware and not a hardware fault.
Basically if you reboot the phone, 9 times out of 10 there will be absolutely no signal whatsoever on the 3 UK network, the phone will just state emergency calls only. This happens on both 3G and 4G, but we usually have 4G turned off as there are not many areas within our region that support 4G yet. If you search Available Networks 3 doesn't show up.
Usually leaving the phone for hours the signal will come back, but sometimes it can be fixed by going into the Test Menu by putting *#*#4636#*#* into the dialer and going to Phone Information -> Toggling the Radio off and On a few times, but this doesn’t work every time. My phone is also on the Three network, so I have tried putting both SIMS's in the OnePlus X at the same time and the same issue occurs in both SIM Slots. If I put a Vodafone SIM in as well as the Three SIM, the Vodafone SIM works absolutely fine, regardless of the SIM slot it goes in, but it maintains a signal each time. The problem isn’t signal in the area as we have full signal in our house. If I put my wife's SIM into my LG G4 it works absolutely fine 100% of the time.
Three will not help us as the phone isn’t supplied by them, this is getting to the point now where this phone is becoming unreliable to use because if you have to reboot, chances are you won't have any signal for hours on end.
This happens on OOS and CM13 and has done for months.
Has anyone come across this issue before?
Just wondered if anyone else has experienced this?
All these views and no replies
I have the same problem and solution is nowhere to be found...
Did you find any solution to this? I've got this problem with my OPX.

My wife ended up getting rid of the phone a few months ago, she couldnt put up with it any longer as it was just the same. I don't think it was a hardware fault with the phone as it worked fine on any other network but Three. The phone supported all the frequencies that Three offers, so I have no idea why it didnt work right but certainly something wasn't right.

When I had recently visited the UK, I had trouble connecting to the Three as well(through my home SIM as International Roaming). It didn't work so I ended up buying an O2 SIM that worked just fine.
I fixed it by putting some scotch tape over the back of the sim card, My OPX is almost 2 years old and the sim card is not in good contact with the phone inside I think.

Hello,
Ive been facing some network issues on my new OP3 (bought 1 month back)
The phone didnt have any problem at all till yesterday when there was a sudden loss of signals in both my airtel SIMS.
OP3 is recognizing the SIM cards but doesnt show any signal. I tried swapping SIMS, my SIMS are working in other phones whereas other SIMS still dont show signal in mine.
However there were 2 instances where i regained signal and was able to make calls while is was at a particular location, but even that lasted for just 20-30 min.
I was using android vers 3.2.4 when this problem happened, tried updating to 3.2.7 (latest) but it still hasnt fixed the issue.
Thought it was a null IMEI problem, but Settings show IMEI nos. of both the SIMS
Tried manually selecting networks, mostly it says cannot connect...sometimes it doesnt do anything
Tried changing preferred networks in *#*#4636#*#* , hasnt helped either
And yes I tried soft and hard resetting too, hasnt helped.
Please do suggest any probable solutions.... Thanks You
Recently successfully unlocked an M4 from Canada. Put in my local, brand-new working SIM card. No network, emergency calls only. Tried to change to WCDMA(only), back to LTE etc... nothing. Tried to manually search, saw various networks, tried to register, failed to register on network. Phone is unlocked, I tried the SIM in another unlocked Sony, got signal. Updated to MM, same problem. Is there a baseband issue? Regional lock? Network is seen but can't be connected to. Suggestions?

Most android phone don't have a separate "network reset" like iPhones do. I just took the phone to a different city with better coverage, got full bars but went back to no network available after a couple of minutes. Kept trying to make a phone call but kept dropping the calls before losing bars. Any ideas?
My Mrs has had a similar issue with her M4 Aqua in the UK sometimes she just gets no sim - no service and has to restart her phone but there's no pattern to how or why it happens sometimes it doesn't happen for like 2 months and then then she has to do it 5 times in one day...
This is across different roms and different sims.
Seems Sony cropped out on something to do with signal pinging on this phone because a few other members have mentioned a similar issue
Hey all,
I am hoping somebody can guide me in regards to an issue I am facing.
I was working on my car a few days back and left the Elephone S8 on the car seat not realizing that it was being hit directly by the sun. After I was done, I picked up the phone and it was very very hot. I then went inside and let the phone cool off.
Since the above, I notice that I struggle to pick up reception. I have tried different firmware, replaced sim cards, everything. It seems to only be affecting certain MHZ bands as 4G LTE work, 3G works fine, and 2G works find but not always.
I have a feeling the 2G is having issues but maybe only certain bands. I do not think it is software related but have no idea where to even start on the hardware side. I first want to try scan for towers and see which bands they use and try see which one could be giving the issue. I don't expect it to just be a lose connector as the phone has not been dropped and I have only been using it for 2 weeks. If I do send it back under warranty for repairs, they will never pick up this issue.
Elephone S8 loss of network issue
Hi.
I think is a hardware issue as the same thing happened to me after 3 weeks perfect use.
I think has nothing to do with the sun as for me happened on a snowy Sunday 10th of December in London.
I suddenly noticed that when sending email the sending would start fast and after a 2-3 seconds the network will drop to 3G and stay like that for long time until the mail app stops sending process and the phone goes back to LTE 4G.
Also when dialling a number the phone will drop from 4G to 3G and than loose the connection straight away.
When indoors the phone would have trouble registering to network for ages without success.
I picked up 4 different pay as you go cards to make shure that is not my network but still no success.
All documented in the support ticket to GB and yesterday have send it back for a refund.
I really like the phone but i am reluctant to buy another if the issue persist so will wait and see.
Hope some more comments will follow to highlight the problem and influence a solution to this.
Cheers
I have the same issue - my wireless connection inside my home keeps dropping and connecting off and on again and again - I have two routers and maybe as I move from room to room it tries to connect to the closest router or something like that - not sure if there is a way to fix it without doing something in the routers.

Same problem here
My network problems are a little different. I don't have problems connecting to different wifi networks (home and work) but the phone does not activate mobile data when leaving a wifi network. I always have to restart the phone when I want to use mobile data (3G).
Kind of the same problem. Have my S8 for about a month. First it has a wifi network. When I leave the place where it is connected to wifi, it goes to 4G. But when I come back to a place with WIFI, the phone does not find any WIFI network. I have to reboot the phone. Soft reboot(a little faster) will also do/work.
Are you guys on the stock ROM?

I have the same problems with stock rom and eragon rom. I don't have a solution but I'm still hoping for a new update.
For now I found out that turning flight mode on and off again helps to switch between wifi and mobile data, so it is not necessary to reboot the phone every time.
I can confirm as well that Eragon won't resolve 3G / 4G network issues.
I'm using my S8 for a week now with only one problem, call related.
No wifi problems but after one day of usage I couldn't use mobile data anymore I almost re-flashed my phone (unlocked bootloader, rooted and using Xposed). Turned out my provider f*cked things up. Probably because Elephone is a not known brand here. It took me some time to convince the agent on the phone that I do not own a Samsung S8 lol.
Problem was solved at the providers end.

This information sounds interesting. How did you manage to 'convince' the providers agent that it is not Samsung? And what did you tell it instead?
Steve the issue you have is different. Your issue won't be resolved that way.
You would need an app that switches to 3G/4G if WiFi is not connected.
Happy too soon. After one day with mobile data it's gone again. There's a cross in the lower right corner of the mobile data icon in the status bar. I'll be calling my provider again tomorrow morning.

I'm not sure if the fact that I own a brand that is unknown here causes the mobile data problems. The problems I'm running into atm are
- mobile data problems, 4G is connected, but no internet
- fingerprint scanner doesn't work with my banking app
- backlight bleed in the middle of my screen
- after 3 out of 4 calls, phone freezes for about 30 seconds
- rattle in fingerprint scanner
I guess I'm about to find out how good the return policy at Banggood is ?
I highly recommend that you return the phone now.
There are so many issues with the phone that it's just not worth the time.
Hi guys, I just got the phone, but mobile data is not working. Am I missing something?
Can you attach a screenshot

Does your sim card work in another phone? If so, are the apn settings the same?
I managed to resolve the issue.
I'm trying to figure what went wrong at start. When I got a phone I inserted both SIM cards like this:
SIM 1 - my business phone number - provider 1
SIM 2 - my personal phone number - provider 2
I wanted to use data only on my personal phone number, so I disabled data on business number. What happened is my business SIM downloaded APN info on first boot (i assume), and then my personal SIM used this APN (which was incorrect).
To resolve issue I first inserted my personal SIM to slot 1 alone and booted. Then I changed APN profile to match my old phone's, turned off phone and inserted my business SIM to slot 2 and booted.
Now data works fine. Obviously there was APN issue but how come that phone didn't get correct APN settings per SIM?
Thanks for support!
