Losing GSM signal very often
Hello everyone,
Since I updated my phone to B815 version I have noticed that my P7 recently very often loses gsm network (like no sim card is inserted), once a day. First I thought maybe sim card doesn't fit well and get the new one from the operator. But still the same issue.
In that case, first I enter airplane mode and then turn the airplane mode off. But it is very annoying. Does anyone else have the same issue? Any solution? My P7 is one year old and never had this issues until last month.
Also, when the display is turned off, the phone went into "sleep" mode which result that I do not receive viber messages instantly but only when I enter viber application. That is the issue from the beginning, no matter on software version installed.
Thanks for reply.

I've experienced an issue with the signal constantly dropping and gaining when using a gsm sim card.
Restarting the phone doesn't help. triggering airplane mode doesn't help either.
First time i put t-mobile sim card in, it works for a few hours and this happens since then. sometimes i try putting in my friends' sim cards in and it works for a few minutes.might this be a software problem?
this is a short video of the issue in case you can't imagine what I'm talking about youtu.be/nOw3jZyiNBA
I have been using my Htc one from the past 2 years using the same sim card. Since i stay in India, the phone goes into roaming mode when you travel across states. So 10 days ago, i travelled to another state and my phone entered into roaming mode from then my phone cannot be connected to the network. I am unable to use the cellular services. Sometimes my phone works fine but the next minute, i loose the signal again. It is not in a stable mode, it keeps loosing and gaining the connection. Neither can i call nor i can text. If the phone gains signal, it happens only for a minute or two after that, it looses the network again.
My sim card is fine since i checked it in other phones. So the problem is with the phone or the sim tray.
What should i do?

Click to expand...
Click to collapse
Seems strange it happened after / during traveling
I have herd of others putting a piece of tape on the back of the sim to make it a little thicker. be careful doing this though the sim could get stuck in the phone permanently
Hi MI5 community,
I am unable to use mobile network flawlessly in my MI5. Sometimes SIM1 running, SIM1+SIM2 both running, none of SIM card works. 2 weeks back I mistakenly selected the radio band as USA Band from *#*#4636#*#* -> Phone information1. Then after a fresh flashboot ROM installed problem solved automatically, but ideally this should not be. But now I am having terrible issue with SIM1 and SIM2 signal reception. Finally I have successfully write NV Values which was originally. But even after setting up values to the original, I am not getting mobile network signal. If I put only one SIM card then status bar says No Signal. If I put both SIM then 1st one says No Signal and 2nd one says Emergency calls only. Sometimes randomly SIM1 runs but SIM2 not. sometimes both not, sometimes both. Frustrating experience ever. Would appreciate if anyone can help me.
Looking forward some help from @TheUltrametricSpace especially.
I don't know whether i can help or not but i used to have mobile network fluctuating issue. At the same area, my SIM1 AND 2 will goes from 5 bar to 0, then came back to 3, then back to 0 then back to 5 again. It happen countless of times during the day(or even night). But the problem fixed when i switched to xiaomi.eu rom for mi5. I did do clean wipe system, data via twrp before i switched to xiaomi.eu rom.
Hope that helped
Hi @yChoon
Thanks for adding some views. Yesterday full day I was in latest EU ROM and the whole day I couldn't able to receive any signal. But around 8PM I have received signal @sim1 only. I hope I will be able to find out the culprit someday. But completely clueless

Hello @yChoon
I'm having the same issue as you with my Mi5. Did you ever experienced those issues again?
Hi guys, I have an issue with 4G after the last dec update. In 4G/3G/2G auto connect mode, usually the receiving data arrow ( v arrow below the 4G symbol in notification bar) gone missing and thus the connection got lost. Only transmitting arrow is visible (the ^ one). I have to wait for some minutes or turn to flight mode and back to get my data connection back.
In the beginning I don't really sure this issue is caused by the latest update, but after I tried nearly everything, including factory reset which is doesn't help, I think that the update is the problem.
I have tried my sim on another phone and it worked normally. I have tried another sim on my note 8 and it got the same problem.
Oh and this is only a 4G issue. My 3G works normally. And before the update, I never experienced this kind of problem.
Two of my friends got the same note 8 and one of them is also using the same carrier as me, but neither of them experiencing this issue.
Anyone can help?
Thanks in advance
I had this issue too, it seems 4g connection only got the problem...,
Problem solved, they replace my device
I have the same problem but seems like in a different way, when I got the phone first time I contacted my service provider to activate the 4G service cause it was inactive on my line due to provider's issues, anyway the phone worked on 4G for only 2 days, after that it kept working on 3G, I contacted the service provider many times but they have no issues with my SIM or handset.
I still don't know what is the problem, is it a hardware malfunction? Is it an installed app? Is it a Samsung Update? I don't know!
have tried getting a replacement sim card, I had same problem in the past and they had by mistake sent a sim that was not 4g, got replacement and problem solved
Well, the problem is that it worked at the fist time on 4G so the SIM was 4G not 3G, but I have just comeback from their store, at the first the technical support did something in their system and switched the phone to airplane mode then turn the network ON back and the deice worked on 4G but after a couple of minutes the phone switched to 3G without going back to 4G, then he advised me that this problem either a SIM or handset problem and it's always 90% SIM problem, so we changed the SIM card and the phone is working on 4G for around 30 minutes till now, I hope it will keep working on 4G
2 days and phone is still working on 4G, it was a SIM card problem
Aoa dear

Hi,
In recent weeks, I am seeing that my phone is sometimes reporting as switched off when called from another number, even if it has network coverage. It happens with jio sim and pie update now. I am also unable to place calls. This happens mostly during early morning,when phone is not used for long time. This gets resolved once I toggle airplane mode on and off. Not sure if its a software issue. Is any one else facing the same ?
