The same thing happened to me today and I’m concerned too. My dad sent a text to me and even though we already had an open text conversation this text wasn’t added on to that one. A new text was started and I noticed a contact named; email@example.com. was added on to it.He sent me a text to ask if I want to meet him for coffee tomorrow. I’m kind of uncomfortable with the fact that this Coffee@sprint.internal.com now knows where I’m going to have coffee tomorrow and exactly what time I’m going to be there! I’m very concerned this could be a security issue.
