OK so here's my problem. I moved back in to my mom's for the time being, it out in the country so of course sprint has no or weak service. I called sprint and they've sending me a airave. That's great and all but we don't have dsl. All we have is a tmobile mifi, that works great Btw. Is there any way to hook up this airave to a mifi? Or is there a app I can use to make wifi calling?
