Problem with phone signal

Hello!
I spent last week in France and I had a lot of problems with GSM signal. Phone sometimes can't connect to operater. When I looked in settings menu I saw only ''searching'' and nothing happend. Then I just click on ''Find network'' and after some second everything was OK.
For me is this a big problem because I must be reachable all the time.
What could be wrong and how could I solve the problem?
Bye,
Borut

I'm on radio 1.38.00.11, and I have the same problem too... sometimes it does not even get any signal after trying to "find network". When I disable the phone and enable it again (flight mode and back) it will get full signal, I'm at the same spot for the whole process so its not the reception of the location.
Any idea?

I sent also an E-mail to HTC support team and still waiting an answer.

I got this answer:
Good Afternoon,
?
Unfortunately this can happen sometimes when roaming, especially if the SIM from your network does not have the preferred roaming partners programmed into it.
?
What tends to happen is that as the phone is switched on in the new country, it will automatically search for all networks in range and then systematically attempt to register and connect with all of them one by one.? Sometimes, depending on the speed with which the networks respond to the handset's requests to register, this can take a few minutes, especially if there are many networks in range.? It can also happen as the signal from one network disappears and the phone must begin this process again.
?
One thing I would suggest would be to contact your Operator and ask them for the name of the preferred roaming partner of the country you are travelling to and upon arrival in the country, you can manually select the network to connect to.? this should then tell the phone to keep with that network until it loses signal, but it should automatically return when the signal is found again.
?

Help with Hero losing signal

Hello everyone.
Recently, my hero has been randomly loosing signal to my network provider. It seems that if I use the phone, it never looses any signal, but when I unlock the phone after a while, I see that it has no service. If from there I put the phone in airplane mode for a few seconds, and then turn airplane mode off, it generally catches the signal again. Also, if I scan for networks manually, I can see all the networks in my area, but I receive a message saying that my SIM card does not allow this connection.
Also, this has happened throughout a number of ROM's and Radio's, so it cannot be ROM specific.
Has anybody else got any tips or ideas as to why my signal is dropping? I can also post my logcat later today if it will help.
Thanks!

I have this problem .
I can not call or receive call.
Help us please ...

it can be your radio that might be causing the problem?

try updating your PRL

Thanks for the support guys. It turns out that my SIM card was actually kicking the bucket, and so I went into Virgin Mobile, and they replaced it in 5 minutes. So far, no problems...so it seems sorted.
Thanks anyway!

[Q] GSM Issues

Hello,
I got a new Lg G2 D802 a week ago and have some srtange issues with it. Although my phone seems connected to my GSM provider about once a day i notice i cannot receive/make calls. Only thing to fix it is by rebooting the phone. It tried going in to airplane mode but it doent help and GSM signal still appears to be full while airplane mode is on. Basically its like i have no gsm signal but phone says its full.
This happens while i m sitting in my office with full GSM signal, another colleague next to me with the same device and provider never had this problem.
Has anyone else had this problem? Do you thing its a hardware or software issue? I tried searching for it but didn't find anything relevant.
Thanks in advance.

I also noticed in Settings the "Mobile Networks" option is grayed out when this happens

Network Mode not working

On my K3 Note, I can't pick preferred network mode on ANY rom/firmware.
I've tried everything, but it always sets the default preference which is 4G>3G>2G.
What I need though is permanent 2G and I can't set it this way. (4G signal is weak on my operator and then it keeps switching between 4G and 2G over and over)
Is there any way to entirely disable or block 4G on a phone so it will never set that mode again?
Any help would be appreciated!

Any help guys? No one knows what could be the issue?
I tried using the *#*#4636#*#* code and set the "GSM Only" but it still doesn't work.
Is anyone else having the same issue?
Edit:
Also what I've noticed is that while using CyanogenMod (atm), it stays on 2G until I turn the screen off. Then it goes back to 4G.
After turning the screen back on it then goes back to 2G again.

same problem here when dialling number it said invalid MMI code and when switching to 4g the other network appear no signal.. hope someone here have solution. i try several roms but same problem issue.

Well after a lot of fiddling, it seems it works on the stock firmware, but the mobile operator as himself has quite troubling network.
But I think we are slowly coming to a conclusion..

P8 Keeps dropping GSM Network

Hi All,
My P8 (GRA-L09) running B399, but happens on all builds, sporadically drops my providers GSM network signal.
It sometimes shows "Emergency Call Only" but on occasions still shows providers name as if still connected. Now, a quick change to "Airplane Mode" on/off brings back the signal but as I don't know when it drops signal it is more than annoying, to say the least, in fact the phone is pretty useless like this.
Any ideas, please? BTW I have tried changing SIM.
TIA.

My huawei p8 (also GRA L09) only works if I set it up to use 4g and then I cant call anyone or be called. Of I set it up to use 2g/3g connection it loses signal completely. It happened since the last two update, first occasionaly now permanently, even on cust roms, except Magic arrow, that I didnt used yet Have no idea why this is happening and dont have answer on your problem, but just to let you know that you are not alone in this problem Anyone have solution, I would really liked to know!
