Losing phone signal - General Questions and Answers

My Galaxy A01 core loses network signal, when I go to turn on mobile data it doesn't work.
When I go to make a call, a message appears saying "Not registered on the network".
I tried to register it by going into the settings, but it didn't work, I tried to format it and it didn't work either.
I have already updated the Android, I went back to an old version and it's still the same (Android 10 Go edition).
I have to keep restarting it to get it back to normal.
Can anyone help me?

patched to rc8, now no internet

Hi all i hope you can help me, i have a rc8 which i wanted to root so i followed this tut http://forum.xda-developers.com/showthread.php?t=442480 , everything went fine until i upgraded it 2 the patched rc8, now it wont let me sign in using my account details. says that it cant communicate with google servers.
Ok, Since my last post iv tryed flashing it again and again with both rc7 and rc8, and im still getting the same problem. it wont let me sign in to google, i cant connect to google server, so im guessing 3g's not working on my phone as the 2 little arrows arnt flashing, iv also tryed different apn's with no luck.
You should check to see if Data roaming is enabled or not, sometimes if it is disabled the phone wont connect to the data network. After a system update/downgrade. This happend to me after i downgraded my G1.
Just reboot the phone, try to login and you should get a message saying you have no data connectivity (or something like that, its been a while since i messed with that) then just enable 'Data Roaming' and try again. It is important to wait for the message concerning connectivity to appear as i belive it is the only way to access that menu(correct me if im wrong).
It is ofcourse also important to make sure you have all the right APN settings and whatnot right first. Good luck
Hi Seanambers, thanx for you r reply.
I have no way in checking or changing the roaming settings on my phone, as im at the signing on screen all im able to do is create a google account to sign in with, use my current account to sign in with and change my apn's. I really dont understand whats happened. iv tryed my sim in my old phone and the data services are workin.
Well yeah, thats kinda what i mean there is no way to change the data network settings before you have logged in unless this dialog pops up. I am not familiar with the UK firmware but on the US firmware it gives you a message about connectivity where one is able to access the network menu and enable Data roaming.
You should note that this connectivity dialog dosent always appear at least from my experience, but when i rebooted the phone and after 1 or 2 attempts to login in it appeared.
This may not even be the solution to your problem if you can see a edge symbol og a 3g symbol on the status line then this isnt gonna change anything for you.
If you still arent able to get it to work did you buy it at a store? If so flash the original RC7 onto it and take the phone to them and ask if they can fix it =)
Good luck
Cheers =)
hey again, is there a way to compleatly restore the phone to rc8 uk i mean so it reinstall boot recovery system every thing, if not ill try rc7, also link to said files would be nice, thank you
Had the same thing with connecting to google servers, but I found out it only works when I'm on GPRS. 3G somehow wouldn't let me connect, but when I got into the phone it worked again (I think). I have wifi at home, so I'm usually on that. And there was a time when 3G completely stopped working. Only GPRS worked. I installed RC8 (had RC30) and after a few tries it suddenly worked. I don't know I had 3G or GPRS when I connected to google servers. But you should try.
Also, I think there is a way to connect to the servers using wifi. But it's messy and you have to have root. I read it somewhere on the forums (activate without dataplan or smt)
You can bypass the registration screen. Read this:

yeah i looked at that, but dont i need to have usb debussing on for adb to work.

[Q] Error 129 (HELP PLEASE)

I have been receiving an error code 129 on my Touch Pro 2 (Sprint) for sometime now. I finally brought it into Sprint and they WIPED my phone and said it was a software issue. 3 days later the same error message. I brought it back to Sprint and they gave me a brand new TP2. 4 days later I am still receiving the same error message (on my new phone). I brought it back to Sprint today and low and behold they WIPED my phone again, this time they did not put anything back on it, no contacts, no nothing. When I asked them what was wrong this time they said and I quote "DO NOT SINK IT WITH YOUR PC", HUH seriously, I have a WM phone and a Windows PC and I can't sink my phone. They recommended to put everything back on manually and see if the error happens again.
I am going CRAZY. Anyone ever see this before? Its NOT a text message I am receiving, its an actual ERROR, it appears on the top tool bar as and "!" sigh, when I click on it is says Error 129. When I get the error I can not make calls, send text or get on the Net. I have to reboot my phone to use it. Then when I reboot I have noticed my family gets repeated text messages. And once I get the error it comes back constantly.
Any help would be appreciated. THANK YOU!!

If you're experiencing the 129 data connection error, try calling advanced tech support and have them rebuild/refresh your network settings and see if it fixes you. I'm baffled as to the why part.
In any case, I found a listing of all the Sprint error codes and what really catches my eye is the fact it says this:
Error Codes - RFC 2002 (129) 129 Administratively Prohibited Mobile should display "Unknown error. Sign in failed. Please try again. If the problem persists, turn your phone off then turn it on again."
Maybe wherever you were with your phone Sprint wasn't letting you use the net at that time.
I also found the following info you may want to try:
Go to www.sprint.com and log in to your account.
Under My Sprint, click on the Settings and Password link.
Under Account Admin Tools, click "wireless web access."
Make sure your phone number IS NOT CHECKED on this page. If it is by chance, your data has been "shut off."
You may want to check it, save it, and then uncheck it. It could cause something to "refresh."
Also, check Settings -> Connections Tab -> connections -> under Sprint click on "Manage existing connections" and make sure your "sprint #777" is there.
If not, settings are as follows:
Name of Connection : Sprint
Model : Cellular LIne
Number to be dialed #777
Username/Password/Domain are blank
Advanced - Use server-assigned IP address is checked (on both tabs)
Use Slip is UNCHECKED
Use Software compression is CHECKED
Use IP Header compress is CHECKED
You need to soft reset after adding.
Other things to try:
Also make sure your data connection is "on" in the comm manager. I know that is a duh, but who knows.
Start > Settings > System Tab > Update Profile
Phone Dialer > Menu > Options > Services tab > Internet > Get Settings
If you're feeling ambitious with that one, you could then initiate custom NAI entry to device (client-initiated IOTA) by taping start.
That's about as much as I could turn up. I hope something works for you.

Suddenly No service some time after root

So got this shiny new phone and decide to root it for adblock etc.
The root went fine, I used the Xperia-L root zip not the chop--- something. So a while after that, maybe a day or two suddenly I get a No Service.
I went into Settings-Mobile Networks and try to choose the network manually, I couldn't, I can move through Auto and Manual but when I select Manual it always goes back to Automatic. Can you guys confirm that that settings doesn't work? Can you choose Manual instead of Automatic?
Then the phone scanned for available networks and it found my home network relatively easy...
NOW selecting my home network gives me the error "Could not join network right now. Please try again later"(or something like that). A minute after that a toast message pops up "Registered on Network" but I still get no service...
Anyone have any idea? I thought Sony phones are root friendly with them sponsoring CM and all....
I have tried everything. Unlock, relock bootloader, restored TA...flashed stock firmware....taking the sim card out while power is still on and inserting it again.....
So frustrating, thanks for any insight....:fingers-crossed:
It happened with me..
What I did is,
Switched off the phone
Removed SIM card
Restarted phone
Again switch it off
Inserted the SIM card
Restarted the phone..
It worked!

[Q] First ROM install running into "Emergency Calls Only" or "No Service"

[Q] First ROM install running into "Emergency Calls Only" or "No Service"
I apologize if this in the wrong section. I have recently upgraded stock Galaxy SIII (SGH-1747M) to Liquid Smooth (LS-KK-v3.0-2014-02-09-d2lte.zip) The phone was rooted and Clockwork MOD touch restore was installed. The Rom install went fine after I solved a few problems (SD card wasn't formatted to FAT32, was using an older restore at first and it error-ed out the liquid smooth install). It was new so I was going through all the settings not changing anything just looking and getting familiar with it. After I got out of the settings I was faced with Emergency Calls Only. I searched google and this forum and what I found it suggested that I go into Settings-> Wireless & Networks-> More-> Mobile Settings-> CMDA Subscription and make sure it is set to RUM/SIM and not NV. I go in NV was selected and selected RUM/SIM it goes out of the menu I go back in and NV is selected again even tried rebooting the phone and doing it same thing, I made sure network was set to automatic and not home only and that the ACN information was correct. It seems no matter what I do I can't select this menu item and have it stay and only way to get service back is to reinstall and not go into this section of the settings. In total I have probably re-installed this ROM 3 or 4 times plus the original install. I need this phone for work and can't have it going in Emergency Calls Only or No Service and having to re-install it to get service back is getting tiresome. I also installed this ROM on my girlfriends phone and she has gone into this menu and looked around with no issues, she is on the same liquid smooth and the initial rom install. The phones are exactly the same other then the color and the carrier which supplies service to the phones. My carrier is Virgin Mobile (Canada) and hers is Fido. Any help on this issue would be greatly appreciated and I thank you for your time in advance on this issue.

No connection after root

So I bought the Galaxy S7 today from Boost Mobile and it was activated and working. I went to root it and now I cant get any sort of connection back. I've been on the phone with Boost Mobile trying everything and I still cant get it to work. At one point it was in a loop where everytime you reset the phone, it would try to activate and then randomly reboot. I keep trying to activate the phone through settings and thats not working either. Does anyone have any ideas on what I can do?
Is your IMEI still ok?
