Can't save contacts in Sony Xperia I have a Sony Xperia with Android OS 4.0.4. Until recently it worked fine but now my SIM contacts are all gone. I can't save in sim either.

While saving in contacts I used to get option whether to save on SIM or on phone ­– but now I don't get the SIM access: this options simply no longer shows up. I tried it with another SIM, but the problem persists.
I have the problem to save the contact on the contact list 
they said you have to clear data of 
 Setting->App ->All ->Contacts 
then restart the phone.
I tried it, it worked,
but I've to do it everytime I save a new contact?!!!
