Doesn't support VOIP unfortunately... & if someone gets a receipt with the last 4 numbers of your card & then gets the last 4 of your social, they could get access to this account & screw you over. Not the most secure in my opinion. Otherwise I was very happy with the service provided through the app until I stupidly erased the app's data & from then on i couldn't varify my identity because of my phone is a VOIP & never got the text for some weird reason. Fix that & maybe I'll return to chime.
