25 cents minute plan
My plan now is the25 dollars pre-paid plan (pre-paid a whole year 300 dollars). Could I change the plan to 25 cents minute plan? because I have paid 300 dollars for a year's plan, and I use it only a month. if I change it to 25 cents minute plan, will you return the 275 dollars to my account balance (actually I paid more than 300 dollars because of the tax, will you return the tax too?)
Another question is that If I get a text message. Will I need to pay the 25 cents fee? Because there are a lot of advertising text messages I think it is very unfair if I need to pay.
