Plenty of residents are unable to get in touch regularly with their loved ones and friends. Enter the cellphone. Simple cellphones are much cheaper these days and those outside LTC homes often have them (something we note regularly, seeing most visitors with cellphones).
So get a cheap used cellphone. With a cellphone and text messages one can drop a message to someone outside easily. Even to a group all at once with just one button press and the typing just needs one finger.
