Going overseas, currently use Hangouts for SMS ... Will I receive messages from Non Hangout users?

[AC Question]

Hello, the subject is pretty much self explanatory. I'm traveling to Costa Rica for a week and don't anticipate using data or my phone really while I'm there. I'm curious to know whether I can keep in touch through text messages on Hangouts with users who aren't on Hangouts. If you have any info or suggestions I'd gladly appreciate it.
