Samsung corby s3652 show contact?

I'm having a problem with showing the contact name when i receive a sms. Here in Sri Lanka, we get the country code as +94 xxx xxx xxxx. So when i save a number using the country code it displays the name when i receive a SMS. But then when i receive a call from the same number saved with the country code (+94) it wont show the name but the only the number will be displayed. Removing country code will effect on the sms system.
