If you're talking about those text messaged that are sent to your phone and charge you anywhere from .50cents to $9.99 a message, then those are premium messages. Whatever phone company you're with you can you the same resolution. This charge (if you're talking about what I'm talking about) isn't from your phone company, it's from a subscription message service you or someone who used your phone subscribed to by sending a text message to them. It's kind of like calling a 1-900 number but not for the smutty calls. The subscription could be anything, like cellphone wallpapers and ringtones, or horoscopes and jokes. To get rid of it you need to reply back to the text with the word STOP (more effectively in capital letters). If this does not work you can call your phone company and ask if they might be able to help you get the number to the subscriber, and if they can block subscription messages only (or all text if you don't want it). Sometimes they can't do this, so you'll need to call the subscriber yourself. Try typing the name on the message into Google and find their site to contact. Usually there's a phone number there.
