I have a prepaid T-Mobile account and keep getting these 25 cent "Domestic Usage" charges. I got one back in May but never looked into it and got 3 more on July 29th. All it tells me that it was my phone and it was a message.
I don't know what these are and why I'm getting them. I haven't done anything differently. I've been a T-Mobile customer for over 3 years and never got any charge like this until now.
What are these charges?
