How to text/mms i.a. picture during a call to another party, if the other party is NOT (!) in the address book. For example, the other party (with caller ID displayed) has called me and we are in conversation, or I have called the other party by manually typing in their phone number and we are in a conversation. So during THAT phone conversation, how do I send a picture to THAT party? With only the cel phone number known, so no eMail or other social media known.
