Sending e-mail through a pay phone

[Nancy Matson]

Is there a way to connect a laptop computer to a pay phone to send and
receive e-mail? If so what is the device that you would use called?
Does anyone know where this can be bought? I have talked to people that
say this is possible, but no one knows how or what the device is called
that you use. Your help would be greatly appreciated. My parents travel
all winter & we thought this would be a great way to stay in touch.
Thank you,
