Hi i think your mobile is locked by particular provider. So only it accepts your sim card in your phone. If you want use any other sim card in your mobile,first you must unlock your phone you can easily unlock your sony ericsson mobile by using unlock code. If you need unlock code you can visit this site Unlock-Zone.com here you can get the code and unlock your mobile. To get the code you have to mentioned which country is locked now,network provider and imei number. Then they send unlock code through email.
