Is there plan/device which allows for only a select few phone numbers to be called/receive calls from?  I am looking for a phone for my sister with disabilities.  Note: Need a phone without internet capability.

JOSSTA9, we want you to be able to get a hold of your sister at any time. Smartphone requires a data connection and basic phone does not require a data connection. Check out the Verizon Plan here http://vz.to/1Je4AlQ and the devices http://vz.to/1TiwgJ6.
