How does BigPurplePhone stop spam calls and text messages?
BigPurplePhone has an optional Safe Callers List which blocks unknown numbers calling.
When you first activate your phone, you can enable the Safe Callers List. This will stop anyone who is not a saved Contact on the phone calling you. Only the Contacts that are saved to the BigPurplePhone can call.
When you set up your new BigPurplePhone make sure to add in all the people that you think will want to call - family, friends, the doctor and the dentist for example.
If a person is not on that list then they cannot get through with Safe Callers List enabled.
