How to copy text messages from one phone to another?

I recently just got a new phone. I switched the SIM cards out hoping that all of my text from my previous phone would still be on there. To my surprise, they weren't! But there were text on there from another phone I had a while ago. Is there a way to copy the text from my previous phone to my current one? Both phones do have a SD Card if that helps. The previous phone is a T-Mobile SDA and my current phone is T-Mobiles The Shadow.

Thanks!

put text messages in sd card. then put in the other phone.

hopefully that should work.

Forward the text to another cell, then resend to your new phone. You cannot copy to the sd card.
