Imessage to SMS
I noticed when I text someone with an iphone that the text starts as blue and stays blue for 20-30 seconds but then changes to green. It stays green if I try to text again but then after a few mins it changes to imessage (blue) when I go to send another text. Does this mean I'm blocked by this person? I'm confused as to why it changes back to imessage (blue) after a few minutes if I am blocked. Couldn't find anything online that answers this.
