Can I block messages the same as phone calls?

When you block a number, the person owning that number will not be able to contact you, either through calling or texts. Usually, there is no need for extra steps in order to also block the incoming texts from a phone number.

How do I know if someone blocked my number?

If you hear just one ring before your call goes straight to voice mail, most probably you were blocked. Also, if you get unusual messages when sent to voicemail, like “The number you are calling is temporarily out of service/ not accepting calls right now/ unavailable”, then chances are you’re blocked.
