Apps which allow to txt or message over WiFi?

[sdmf]

Hey guys, in canada here. Looking for an app that I can install on my kids phones, which DO NOT have a plan, they just use for YouTube and games.

I would like to have an app that I can message them to check in on them if I have to run out to the corner store for a second to make sure all is well.

I tried whatsapp and txt+ but couldnt get that working as they wanted to link to a phone number, which as stated above they don't have.

Any help with be awesome.

Google hangouts is a texting app which only requires wifi

Omg thanks so much. Installed (well updated) on their 3 devices, tested and works great.
