advise re Walmart prepaid/no contract cell phones
I'm in the market for a no-contract cell phone for my son. I understand Walmart has the best monthly price? I anticipate that he will use it mostly for talking & texting, not so much for the web browsing. I was checking Walmart's website for info, but that seems to be mostly about the phones. There's not a lot of info regarding the service itself. Can someone help me understand the service? Is it a Walmart service, or do they contract with a national provider such as AT&T? Is it pay-as-you-go, meaning my son can purchase more minutes when he's out? Or is it a flat monthly rate no matter how much or little he uses? Do I have to purchase one of their phones, or can I use a phone I purchased somewhere else, or maybe my husband's old phone?
TIA
