How to block messages from unwanted number in sony ericsson txt pro

SOURCE: blocking numbers

Call your provider and ask about blocking incoming calls from a certain number, I looked into it and there is no such function in the phone, you can restrict outgoing calls and you can get a accept calls service which only allows phone numbers you select to call you, but thats not really that good of a service, how will new people call you? you will always have to add their number into the list. Better to ask the provider for a call block on a certain number or just keep pressing the busy button or turn the phone off, or maybe use a prepaid sim card for few days so you have another phone number and the caller won't know the number. 
good luck, let me know how it turns out,
