No sim card in phone

[crazyshan78]

I have a sony ericsson experia x10i mobile phone and whenever i insert a sim card it is always saying that there is "NO SIM IN PHONE". CAN YOU HELP ME OUT WITH IT SO I CAN UNLOCK IT AND BE ABLE TO USE IT. The IMEI NO: is 012379001567050

It may be an issue with the SIM card. I'd get in touch with your carrier and see what they have to say about the issue.
