How to block numbers on Alltel wireless plan?

[Unpretty]

A friend at work is being harrassed by a coworker. He got her number off someone's phone and keeps sending her messages about her being hot and wanting to get to know her better...nothing threatening...but she's afraid that (since he tends to text her a LOT when he's off work for the day and half drunk) her husband will find the texts. Even though she never did anything with this guy, her husband would never believe it...he doesn't trust her.

Anyway, she wants to block this guy's number to keep him from calling or texting, but she's afraid that, if she calls Alltel, it will show up on her bill and elicit questions from her husband. Is there any way to block his number from her phone without calling Alltel?

It's a Samsung R500, if that helps.

Thanks in advance if anyone can help. It's getting bad...as in about 7 texts in a ten minute period, and even when she asks him to stop, and tells him the truth (her husband), he doesn't listen...she's tried everything.

I had a similar problem a few months ago from some drunk idiots who didn't understand they had the wrong number.
