I was reading up about your problem and I saw that AT&T doesn't provide Wi-Fi calling, unfortunately. You could however try using a VOIP application (voice over internet protocol) such as Viber, Skype, Fring, Line2, Tango, Liphone, Groove IP lite or WiCall. Some of these won't cost you anything or are at a low cost and definitely won't break the bank.
I hope this helps!
