Need a cell phone where I buy minutes that don't expire
I bought a T-Mobile cell phone from Costco on Sat. but when I went to buy a phone card for it, I discovered that the minutes expire after 30 days. So if I don't use those minutes I threw my money away. I will return the phone to Cosco tonight, but can someone please tell me the name of a cellphone provider where I can buy minutes that will not expire except when I use them up. Does such a one exist or do I have to take a $29.99 a month plan that will really cost me around $38.00 after surcharges and add ons.
