The only way you can tell is to bookmark the product page and check often to see if comes back in stock. Otherwise, call local stores in your area and see if they have any.

Hi there hisamith,
It's fantastic to hear you are interested in the Lumia 640 for AT&T! With that said, I'm sorry to hear it may not currently be available. As hockeycanuckjc suggested, I would encourage you to keep an eye on BestBuy.com for changes in availability.
