Sony Xperia T No SIM card problem

[fuvi]

Hello!

I've got a Sony Xperia T phone, I have it for a year..

But in a two weeks I guess, the phone is giving me an error about no sim card, and than restarting.. And thats for twice a day.

My SIM card is not a cutted version, I've got it from my carrier. The phone is not rooted at all.

Upgraded to Android 4.3.

I've tried to take out the sim card, and than putting it back, but after a day, I've get the error again.

Please help me, this is so annoying, because the restarts drains the battery..

Thanks,

Viktor.

Have you tried booting in safe mode,see if the same occurs?

I think you might need a new SIM.

Same here. Factory stock phone. (simlock free)
Sim = not home cutted.
Stock android, not rooted (never tried)
Never had any problems like rebooting etc etc.
After 4.3 update the reboots now and then. Stressed or standby doesn't matter in what state.
You get a vibrate and then a message with sim/UIM removed(or disconnected don't remember). Then you get the message that the phone is shutting down. And then powers up again. Noticed that gsm network state = 0 (red x with the bars).
Don't really think this the sim as the phone works also without one.

Battery level doesn't matter either.
Feels more like a software conflict of some sort

I had this problem after the 4.3 update. 

I backed up my data with PC Companion, and wipes and reinstalled the software with SUS. It seems to be ok now.

I have to come back on what I said before.
My message:
SIM/USIM removed, turning of phone/rebooting phone(one of those 2.
I then removed my sim and no problems occurred so far. Running without any problems now for about 12hrs straight.
Only thing I can't do now is calling someone or receiving any calls(and that's the main purpose of having a phone).
And tbh this "SIM removed" error shows some eary similarities as how my class 10 32gb microSDHC uhs-1 card came to an early end of his life 😕

Remove the SIM PIN query with the another phone (hope you have one...). Does that help? Worked for me...

I am having the same problem! These phones are so unreliable!! I want my money back sony. From dying while charging, from re-boots, from now SIM card not working, from flickering screen, from garbage phone. Please contact me so I can get my $400 back. 

Edit: This problem might be the SIM card actually. I took a pencil and put some graphiteon the scratched up parts of the sim card (from where the little sensor touch it it looses some of that gold color) and now it is working. So I ordered a new sim card. Lets see what happens when I get the new one. 

Still too many problems overall.

If James bond had this phone he would not be James Bond for very long.

Yeah I can relate to how crap these phones are. I wanted an iPhone, but was talked into a Sony. It's been sent away to be fixed for not charging up. Now it's come back and,won't read the sim card!! I've used the soft reboot. Took card out. Turned off and on. Nothing works. My phone is also used as a business tool as well!! So frustrating. Sony! sort it out!! :@
