Hi Ladies & gents,
I'm new to this forum, and new to android.
Basically i was given a Samsung Galaxy ace by my brother (was on o2 network, all working fine), and i decided that i wanted to try & unlock it.
In the process, i rooted the phone successfully, and downloaded galaxy tool box, to unlock it. This was all carried out using an sd card from my pc.
After the procedure i changed sim to 3 network, and found the phone saying "no network coverage."
I checked the settings, and under mobile networks\network operators if i click on search networks, "searching flashes up for a second and thats it!
If i try select automatically it says "unable to connect to network. Try again"
The phone shows 3 out of 4 bars signal, and when i try & call someone it says "no network coverage."
Have i goofed up, as i now have a phone that works fine on wifi and everything else except to make non voip (skype etc) calls!
Please help?
Thanks in advance.

Hi
I found the said phone in a field !!! at a music festival....
I unblocked the phone in shop so it would take my Vodafone sim..
It worked for 2 days and now i cant make or receive calls, texting etc
I have tried to search for a network provider but when its finished trying to register to Vodafone etc it says sim card doesnt allow connection to the network
i have tried going into factory settings to no avail....
have tried galaxy toolbox but straight away as i click onto it says 'failed to acquire ROOT access!'
very forceful hey !!! haha
am running out of ideas and am not a tech guy although i do want to learn more now.
Do u think the person who left the field has done something via their network provider that has done something to the phone
I am in England..... thank you for your time
I've had this samsung galaxy ace s5830i (my first android) for 4 of the most frustrating months now.
The problem first started with the phone being stuck on EDGE regardless of signal strength. I tried flashing it with new roms but had zero success. I tried manipulating the menu under *#197328640# but that led to a dead end as well. Every time I tried to select WCDMA only, the network bar changes to a "circle and cross" type of thing. I tried to dial *#7465625# to check for network locks but everything reads off i.e. no locks of any kind. Finally, I tried to select a new radio band by dialing *#4636# but that operation crashes a "com.android.phone" everytime.
So in summation, service mode changes don't help and flashing the rom doesn't help.
Recently, I to switched one of the strongest networks available (other than the one I'm on) but the phone is stuck on "emergency calls only" mode. When I try a manual network search and select the network to which the SIM card belongs, I get and error telling me that the SIM card can't register onto the network.
I have used these SIM cards on nokia phones and other samsung galaxy ace devices and have experienced none of the problems listed above, even in remote areas. The support guys of my network say nothing is wrong with my account.
So there you have it. Is there anything left that I can try?
Hey all,
I have a Samsung S3 which I bought today, the guy I bought it from said he originally bought it on the Vodafone network (UK) but he had unlocked it. When I put in my T-Mobile sim in it worked fine, the phone was running on Ice Cream Sandwich 4.0.4. I installed Jelly Bean 4.1.2 after watching a Youtube video successfully.
However, when I put it my sim card, I can use the phone but it says 'not registered on network' when I try to make a call, and when I pull down the menu it says 'emergency calls only'. Internet works fine on WiFi.
I checked the Imei number, its all correct apart from the last two digits have changed, which I checked with the Box I got it with. What have I done? I am a noob at these things I hope I haven't messed up my phone Please help.
You should verify a few things. Are you 100% positive that you installed a tmobile rom? There are many varients for the gs3. For example i'm on atat, I can flash a sprint rom which will boot up but I cannot get data to continuously work. If that doesnt apply then go to settings menu>wireless&network>mobile network. U should see an option for selecting network provider. Select manual search and give it a few minutes to find the networks and choose your network. Reboot the phone after and it should be good to go. If after that you don't have data service then you need to verify the apn it's correct. It's located in the same mobile network menu. Good luck.

Hello there,
I am trying to get my Verizon Galaxy S3 to work in Germany. I have rooted my phone and flashed JellyBeans vs. 0.1.8.
I followed the steps in this guide:
http://forum.xda-developers.com/showthread.php?t=1809314
When I am in the Mobile networks settings, I have changed the access points name to Vodafone (the carrier I am trying to use ) I have already changed the Network mode with the Phone Info app. After I try to change the access points name, it asks me to select a network operator. My phone then begins searching and it lists Vodafone DE as one of the options to select. When I select that option, my phone tries to register this option, but eventually it says "Unable to Connect, Try again later"
Can anyone offer any advice as to how to get my phone working with Vodafone? I've read and reread the guide I listed above, as well as searched for other threads that talk about issues similar to what I am experiencing, but I haven't had any luck. I would appreciate it so much if anyone has any suggestions!
Thanks!:fingers-crossed:
Hi folks,
This is my first post on here. I'm having a problem with my phone which I think is quite unique and I hope someone on here can help me fix it before I buy a new device.
I have a galaxy nexus (maguro) running cyaogenmod.
Previously I was running CM11 (cm-11-20141115-SNAPSHOT-M12-maguro) from the CM website and updated it to CM12.1 cm-12.1-20160719-SNAPSHOT-YOG7DAO8DL-maguro) a few weeks ago.
When I rebooted my phone it was running very slow (and getting very warm) so I did a factory reset and re-installed CM12.1.
It started working ok but I noticed that my phone was displaying 'emergency calls only' even though the network reception in the status bar was full, displaying 'H' (3g) and allowing me to connect to the internet using 3G.
Whenever I make a call it states 'Mobile network not available' and I cannot send text messages.
I tried phoning O2 and they gave me a new sim but the problem was still happening. I then tried putting my girlfriend's EE sim into the phone and I could make calls/send messages. I also went to France on holiday and could use my phone to phone/text using my O2 sim abroad. Whenever I put my O2 sim into another phone I can make calls and text.
So basically it is only when my O2 sim is specifically in the Galaxy Nexus that I cannot make calls/send texts but can still use 3g.
Oh yeah when I go to Settings>Mobile Network Settings>Network Operators the following available networks are shown:
O2-UK
T-Mobile UK
3 UK
vodafone UK
Orange
When I select O2-UK is states 'cannot connect at this time. Please try again later'
I've tried re-installing the older version of CM11 and today I tried wiping the entire phone (internal sd card etc) and it is still happening. Can anyone help? Is there something else I can wipe, or setting I can change?
Thanks in advance
