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

Hello everyone.
Since getting a Lumia 800 I've had nothing but issues. Initially the problem was battery life (as is common, I know), which never reached more than 5 hours even on minimum usage. Then I started getting signal dropouts. So I sent it back to Nokia's UK repair centre in Thetford, thinking that they would sort it.
I got the phone back today, and the phone now will not find a network at all - I've tried multiple Microsims on different networks, with no luck. On the advice of the Nokia helpline I restored the phone to factory settings, performed both a soft and hard reset, and tinkered with the network settings app and the mobile network menu in settings.
It isn't a sim insertion error, as a different symbol shows up when no sim is inserted. The phone simply won't find a network, when I know the signal strength is very strong in my area (in fact I'm using my old phone with the same sim card and it has full strength).
It looks like I'm going to have to send it back to Nokia again, but if anyone can help me to save me having to do that it would be much appreciated.
Thanks,
Chris
Try put it on 2G.
Most time 2G get better signal than 3G.

2G didn't change anything, still no service.
I'd the similar issue, the status kept showing NO NETWORK connection, but the funniest part is, I can make call, and send SMS!
The most frustrated part is, the data connection is always drop! I'm not sure is my telco issue or the phone issue!
Have you tried ringing yourself?
I know that sounds stupid but I constantly get the no signal sign but can still call, send texts and receive all, even the internet works.
I thought it was a problem with three (everyone always says they're ****) but the post above suggests not.

Yeah I'd read somewhere else about ringing/texting to wake the phone up kinda thing, but it doesn't work.
Goes straight to answerphone when I call the phone, and when I try and call out it just fails.

Nope, it's doing this to me on the o2, giffgaff and 3 sim cards I've tried.
Where did you buy it? If it was a physical store I'd take it back there and ask for them to swap it over... would be quicker than sending it to Nokia.
I have the same problem with L800. No service but... I can't call, answer or send sms and get them...(Wifi works fine) I tried many different sim cards from different operators etc. Can't take it back to the shop because I bought it used without purchase papers. It just suddenly stopped saying "no service". And when I mess with it and try search the network manually it finds them, but wont connect to any of them. And after doing that alot, it says incorrect sim or something like that.
It lets me put in the pin code and everything.
I tried searching from everywhere but no solutions yet.

Hmmm, ok it's not a simcard issue then, if you tried a lot of other simcards from different operators, did you try to clean your simcard reader maybe there is some dust or perhaps a failure that results in not reading your simcard.
Goodluck buddy,
So today I made an experiment. I live in Norway and I went to Finland. In Finland the phone worked perfectly with out any problems but as soon I got over the country line back to Norway. It said "No Service". Very strange...

Well, then it's solved, just move over to Finland :laugh:
Just kidding mate, it's a strange problem don't think there are a lot of differents between the gsm coverage of both countries.
The only option I can think about for now is to perform a hard reset.
If I found something usefull about this issue I let you know.
Greetz,
Hello, this is my first post on the forums here.
Iv'e purchased a Xiaomi Redmi 3 last week. It turned on fine and after the first turnoff-turn on it simply didn't turn on again and was stuck on the mi logo.
Iv'e downloaded the latest stable chinese rom and flashed using miflash and the phone started working properly again.
The problem is I do not have a cellular signal. It's either non existent (empty bars marked with 'x'), empty bars or one or two bars at most. Even when there are bars I cannot receive or make any calls (when i call the phone it just rings and the nothing happens).
The sim card itself is new (micro), the phone is new. I tried contacting the cellular company and they said everything is fine on their side, also iv'e tried the sim card on another device and it worked. I tried fiddling with different settings like changing from preferred lte to prefer 3g, adding new vpn, changing the sim card settings through the phone from WCDMA, only LTE so on and so forth and nothing worked.
Iv'e read around the forums here about the whole bootloader unlock, rooting, dev roms. I'm a newbie when it comes to these things and don't know weather I should do there and if it would help my problem.
Oh and last thing, I also verified that the device 3g/4g networks are compatible with the cellular companies in my country (same ones).
Thanks in advance,
Maybe there's a problem with ur set. I didn't root nor unlock the bootloader and reception has been fine for me from the start.

So you think it might be a faulty phone?
EDIT: I don't know if this helps or connected to my issue but i have this notification at the top saying "your SIM card isn't activated". I can't link to the pic since i'm a new user.
No one knows how to fix my problem?
I've got a similar problem I think.
I searched until I found that while flashing my IMEIs got lost and so the phone can't register to the networks.
Now I continue searching how to restore the IMEIs...

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
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
