"Sending texts to blocked numbers: I found a similar question to mine but it’s years ago. I’d like to get an updated version of the answer. Can the blocked number receive any of my text or calls? From an iPhone (me) to a non-iPhone (them) user?"

Successfully Sending a Text:
What you are asking is on the recipient. They are not going to get your message if they do not have Messages as a service, nor if they have you blocked out. So, if you are texting them, and they aren't getting it, then ask them to add you to their Contacts list and then remove you from a block list. Texting form iPhone to Android should work just fine. But, if there are issues overall, then have them contact the Carrier.
