What does green message mean on iphone

Why are my texts green? A green text message on your iPhone isn't a sign that your phone number was blocked, or that the text was not delivered. Instead, it means that the message was sent as a standard SMS message rather than an iMessage, which will appear as blue.

A green background means that the message you sent or received was delivered by SMS through your cellular provider. It also typically went to a non-iOS device such as an Android or Windows phone.
