Can You Text and Facetime Using a Deactivated Iphone 4 with working Wi-Fi Connection?

So basically this question is asking Can You Text and Facetime Using a Deactivated Iphone 4 with working Wi-Fi Connection. Because i got my iphone 5 taken away because of some problems that i had in school but she didn't take my iphone 4 that was deactivated when i got my iphone 5 a few weeks ago, i know you can use most apps with wi-fi but i was just wondering could i use Facetime, and text with the iphone 4 that is deactivated using my wi-fi only until i get my 5 back thank you

Can't text maybe you can use FT… Just wait until your 5 comes back
