You can send iMessages using a MacBook Pro.
A cellular phone is needed to send SMS/MMS text messages; however, if you have an iPhone you can send SMS/MMS messages from the Mac by forwarding them through the iPhone. See information in Forward SMS/MMS text messages from your iPhone to other devices - Apple Support
and
Messages User Guide for Mac - Apple Support
