stay away from this

I downloaded this and tried it once and then deactivated it and I couldnt receive any phone calls on my cell, so I tried deactivsting it again and it would just say error. I shut down and restarted and same thing all over. I deleted it and put my SIM card in another cell to deactivate call forwarding. If I hadnt been home to receive a call that was made to my cell I wouldnt have known this app was goofing up my phone!! Still causing problems with my phone even though app is deleted. If I decline a call it automatically goes to my landline! Would be nice if I could get my SIM card free of this app!
