I meant to ask is picture message the same a regular text message if u get 250 a month?

That depends on your plan, in my plan that is multi media and is billed separate, but you have to pay extra to get it included.
So in y our plan what did you pay for.

I don't even text hardly ever and I go over 300 a month easy

According to US Cellular, it is not and is charged at a different rate.
