Ruggedized, Non-Smart Flip Phone for T-Mobile

[SEMIJim]

I realize that, this being an Android site and forum, the question's a bit off-topic, but...

My wife is thoroughly uninterested in a smartphone. I think I'd like to move to TMO, but, unless I can bring her along it doesn't make economical sense and will not happen.

What she's got now is a ruggedized Samsung (I think) flip phone. Is there such a thing we can buy for TMO and maybe add-a-phone with it to a plan I might go with?

Thanks,
Jim
