replaced broken screen, phone works but doesn't recognize sim card, but there are signal bars displayed! I once installed a rom that caused phone not to recognize sim card, but there were no signal bars displayed that time.
did you try flashing another modem?

Hi people.
I've got a new Xperia X10 'cause my old one passed away. A shop SIM unlocked it and it seemed to work. It was on 2.1, so first of all I've updated it through SEUS. Then I turned on the phone, it asked for the PIN, and after that, blue wallpaper with status bar and anything else. If I take off the SIM card and turn it on again, it works, I can use apps, use wifi, etc, but if I turn it on with the SIM card, it just asks for the PIN and show the blue wallpaper...
Then I flashed back and forward from 2.1 to 2.3.3, rooted it without the SIM card, installed MiUI... In MiUI (latest from cobrato and latest from oodie) with the SIM card it works but it never got signal.
I'll probably call to Vodafone tomorrow and ask for a replacement, but I would like to know first if there's a way to fix it...
So a little briefing:
With 2.1 and SIM card it doesn't show anything on the screen, just the wallpaper and the status bar
With 2.1 without SIM card it works
With 2.3.3 and SIM card it doesn't show anything, just the wallpaper and the status bar
With 2.3.3 without SIM card it works
With two different MiUIs, it works with SIM card but it doesn't get signal
Thanks in advance!
hi
the network signal in the notification bar is good (3 or 4 bars) but the error message (NO sim card detected, Insert sim card) always appears and the phone doesn't make or receive phone calls or messages , when you try to make a call it says "you are not registered on a network"
the strange thing is that even with no sim card inserted in the phone , it still shows good network signal . i tried different sim cards and did a factory wipe , still the same problem , What do you reckon ?
Thanks
I reckon you're in the wrong forum. This is the S3 forum. Not the S3 mini forum.
I have bought a Chinese phone a Flying 7100 which is really an Alps 7102 running 4.1.1. I have rooted it but kept the factory rom. The phone is fine and is a big improvement on my old Desire S with one exception. It will not connect to the Home Signal box I have from 3 UK using the sim card from the Desire S, when I put the sim card back in the Desire S it will still connect so the sim card does not seem to be the issue. The sim card when in the F7100 on the normal 3G network works fine and is better at getting and holding onto the 3G signal than the Desire S.
I have tried the following with success only with 3 de-registering and registering the number, this got voice calls.
A. Changed the IMEI on the F7100 to the Desire S value. No affect.
B 3 have de-registered and registered the phone number allocated to the sim. This allowed voice calls through the Home Signal box but data is still blocked.
C.As the sim card is registered with a ported number I have also added the old sim number to the registered numbers list. Under Sim management the F7100 I have changed the sim number to the ported number. No affect.
The phone will initially connect with 5 bars and voice calls can be made but then the aircraft sign appears every 5 to 10 minutes for a few seconds, there is never a sign of a data connection, I have installed Femto Widget lite and it shows the phone is connecting to the Home rather than connected. The normal 3 signal close to the Home Signal is virtually nil.
I have MTK Uncle loaded and there are loads of settings to try but I don't know where to start.
Appreciate any ideas on what to try.
Hi all.
Does anyone know if it is normal to have your Sim card provider listed twice in the Network operators list. As my Galaxy S3 shows '3' twice and O2,EE and Vodafone just the once.
Reason I ask is that I have been having problems with a new S6 not working with my new Sim card though '3' said it was fine.(I had just recently been in to have my sim changed from Micro to Nano size) So I'm currently in the process of sending it back. When I put the Sim back in my S3 it was doing the exact same thing the S6 was. Showing it was connected to the '3' network but dropping the signal all the time and going into 'Emergency calls only' mode. Manually switched to the other '3' in Network operators list and phone now works fine.
I could never recall it ever showing '3' twice so wondered if ther store had programmed the sim wrong.
Anyone?
Cheers

Hi,
I purchased a USED Galaxy A7 2018 dual sim F variant. When I first inserted my SIM card, it was working fine. 4G and calls, all were working.
But after I factory resat it, mobile network stopped working or even detecting. SIM card is still detected and I can see it in "connections" under SIM cards in settings app on my phone. But when I try to dial a number it says "not registered on network". On lock screen, it says emergency calls only. When I go to "mobile networks" in settings app and tap to select network automatically or manually, it gives error that unable to find/connect to a network.
I tried three different sim cards yet same thing happens. SIM cards work just fine in other phones. Also, it is not a problem with sim tray on phone as sim card is detected and shown and as I said before, mobile network was working fine before resetting the phone.
When I purchased it, there was a custom ROM installed on it and OEM Unlocking was ON. I installed latest stock ROM from Samsung plus a couple of stock ROMS but same thing happens with every ROM.
I am out of ideas on what should I do now. I would really appreciate any help anyone can give.
Thanks.
Finally found a solution.
