If you send a text to sumone who says they have blocked their number and it says its sent...
Have they in fact blocked my numberr ?
Of is just telling me bull**** ?x

If I have you blocked on my phone you'll get the "sent message" notification but I don't get the message.

Please watch your language. This is not a blog.

Why anyone would block your message I have no idea, but you have no way to tell.

If they tell you that they are blocking them, it means they don't want to hear from you, so why waste your breath or text on them.
