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?
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.

It woked fine before. I gave my mobile in samsung care to repair my mic.... they repaired mic but when i take my mobile back and attempt to make a call for first time its showing "NOT REGISTERED ON NETWORK".... I immediately showed them... they said its the problem of My sim card, But after I tried with many sims it is not working..... Help me how to fix it...... Is it a software problem or Hardware problem.....
you may need to get the carrier APN settings reinputed into the phone, without the carrier settings the phone will not connect to the data & sometimes with have issues with other connections.
My Korean galaxy note 2 SHV-E205s all voice service work perfect but when I tried to turn on data it says insert Usim Card to access network please help
Hello everyone !
Before you read here is the specs and what I tried but didn't work to solve this issue :
Model : galaxy s5 (klte )
OS : Havoc OS 3.7 latest
Root : magisk21.1
Solutions I tried :
1 - restarted the phone .
2- clear factory reset and reinstalling the ROM.
3- checking my IMEI and its fine doesn't need repairs *#06#.
4- switched Sim cards and tested other Sim cards still no results .
5- return the official android OS still no use .
6- any other obvious solutions didn't work such as backup and restore my IMEI/EFS , airplane mod .
7- choosing network operator in the settings results a crash while searching so I can't choose manually and only be able to let it at automatic .
so lately I just bought a 4g Sim card and I know the galaxy s5 support 4g bands as I inserted the SIM it worked normally yet I wanted to switch the band to LTE so obviously I went to *#*#4636#*#* and switched bands so I can see which one would work yet suddenly while switching a couple of times the signal stopped showing and emergency calls only even though it reads the Sim card .
i tried to manually chose network operator but it crash's while it search's for it no matter what OS I install even in original so if anyone knows a command line to manually chose a network operator that would be appreciated.
Anyone know what to do ?

You may need to contact customer support for your carrier, they may have to fix it in their network.

The thing is about my carrier that they have a terrible customer service in here as if it was almost non-existing so I'm left all alone to deal with the problem plus there aren't any customer service for Samsung or any other external fix center for smart phone that's why I had to learn things on my own.

If you can't get back into that dialer menu and if flashing the firmware isn't fixing it and if booting into recovery and factory resetting the device aren't working, I'm not sure if there is anything you can do.
