Requesting Advice: Easy-to-use Connector that triggers Text Message / WhatsApp messages

[MikeyCas]

Good day, 

Would it be possible for someone to provide the name of a good, easy-to-use connector that triggers Text and/or WhatsApp messages to incorporate in my flows? I recently got in touch with the sales team of a connector on Microsoft, but , but in order to use the connector, I had a lot of coding to do on their website to issue a text message. 

Ideally, I could go on this connector's website, create "Groups" of employees, and send messages by group or as a whole, similar to a subscription service. 

Any ideas?

Thanks, 
Michael
