Yes, you can. It's is under WIND/PARTNER NETWORKS. In these areas your phone could be using either the WIND Network or a Partner network. Your phone will display either WIND or AWAY so you can always tell if you are able to use your unlimited features or if you'll pay our low pay per use rates.

I am currently living in Calgary but moving to Grand Prairie in two weeks. Can I use my wind mobile phone and sim in Grand Prairie.
