How can I tell if my text messages are blocked by someone?

[AC Question]

I was able to block a specific number up in my text messages up until an hour ago, but now I don't get that option? Is it because my texts are blocked on their phone?

Nope. You won't be able to tell if they blocked you because the blocking will be occuring on their end only. Not even the carrier will know if they blocked you.

What is blocked on their phone has no effect on your phone.

Which phone?
Which version of android?
Which carrier?
Which SMS texting app?
