I just bought a sony ericsson aspen running on windows mobile 6.5.3. The problem arises whenever i received an sms. Windows mobile never recognizes the sender even if it is in my contacts. for example the sender would be +60xxxxxxxxx with area code although it is in my contact as 0xxxxxxxxx without the area code. If i change my contacts' number with the area code, windows will not recognize the incoming call as it does not uses area code. how could i solve this problem?
