Why doesn't my Q10 detect my SIM Card?

Hello everyone,
Please forgive my poor english, I�m just a french student who can�t find help on french forums 
I recently purchased a Blackberry to a particular
I bought it a Sunday and I was in a hurry to test it.
I have tried to insert a non-adapted SIM (microsim normally) by making a homemade adapter�
It was not a succes and I broke some pins of the SIM reader, and after that the Q10 did not recognize my SIM.

So I changed the SIM reader for � 60.
When I recovered, the phone did not work with my new SIM (Orange carrier)
So I went back to the repair shop and they showed me their SIM cards (others carriers) worked and that the problem was my card.
So I ask my carrier for a new SIM. Everything works for 2 h, the absolute bliss :)
Two hours late my SIM card is not detected again. Nothing happens to the phone in this time.

I tried everything: wipe my device, updates via BB Link, Blackberry Update via the website, via OTA ...
Two cases occurred to me:
The classic : my SIM card is not detected by the terminal (I tested with a friend�s SIM, it is not detected either)
A variable that happened once: the card was recognized, but the network on the screen appeared as"technical problem".
The Hub sent a message that the phone was locked on the network. (While I managed to call surfing etc during the first day for 2 hours).
If you have any solutions to help me solving my problem�

Thanks a lot for reading me
