try reseating the simcard part (requires unscrewing and removing the back). While the part is removed, check all the pins to make sure they are connected right.
Problem is the following: So far this has not happened but today it happened 4-5 times already, the phone just freeze and not respond to commands, the screen turns black as when it goes off, but do not goes off, after 10-15sec being turned on and the icons appear, but 2-3 times disappear. This happened mainly when the phone is idle and when I try to unlock it, and once when I used it. When this occurs the signal indicator disappear and show a crossed circle, and what interested me most and I can not reveal what, I get a white triangle on the top left corner with an ! mark. What would that character is supposed to, since it disappears when the phone is stabilized.
That white triangle appears when there is no SIM card inserted into the handset.
It seems you have a faulty SIM card or faulty SIM card slot. The freezing up of the handset could be because of the same as the white triangle appears when the handset freezes. Here's what you can do:
- Try to use the handset without the SIM card for a hour or so & check if it freezes again, if it doesn't then the it's a SIM related problem.
- Use a different SIM card & check how it goes.
Hope this helps.

Thanks for the help, I will try it next time when start to behave strangely. When this happened the last time I shut it and pushed little the sim card and then works ok.
I bought a T98 tablet on 4.0.4; but whenever I insert any sim card, the tablet just freezes at the android robot. I inserted the sim card after booting but still froze. what should I do?
A friend of mine bought a G - Tab P700+ on 4.0.4 which was working perfectly till we decided to enter an access point name; but the save command does not work. The thing just disappears whenever you tap the save button. what should we do?
Hello everybody! after firmware my phone does not see the sim card, I do not know exactly what was done with the phone, how to return the phone to factory condition completely?
Sometimes when I turn off the phone for a long time and then turn it sees the SIM card, but after restarting again invisible. help me please!
Hi there!
So i got a NEXUS 5 32GB.
Short story: i had an old SIM card, like 5-10 year old, when i bought the phone. I cut the card into microsim, and worked like a charm. (You know, nexus stuff when no service sometimes like once in a week (restart solved always the problem)). Now i contracted with a new service provider, and the (3in1) micro sim i get is unreadable to the phone.
Detials:
-The new card working in other phones without problem.
-I went to my carrier and get a new sim card, doesnt work either. (so the sim card(s) not defected)
-Tried different SIM cards in my phone-> working only the old SIM cards, new micro sims doesnt
-Tried almost every softwere stuff, (factory reset, FR in recovery mode, flashing 4.4 android, flashing other androids, flashed radio files etc.etc) ->non of them worked.
-We disassembled the phone, the sim reader is looking perfect, not a scratch, all pins in order etc.
-THE MAIN problem: however i insert the new card(s), phone says only "No sim card, emergency call only". Can't even set up the mobile services, nothing. Only can turn on-off the NFC, Airplane mode etc.
-When inserting the old cutted card, works perfectly.
I'm paying now for 2month for the new card, but can't use it....
Please help me!!!
Any kind of help will be appreciated.
Thank you very much.
Have a nice day.
PS.: Sorry for my english, i'm from Hungary.
