Default HELP - My new phone stop reading the SimCard

My new phone stop reading the SimCard after 2 using days ("no simcard" reporting). I am sure It is not a software problem but on the other hand the SimCard socket hardware look like new. Unfortunately I don't have warranty... Any idea how to fix it?
