Hi, I am currently selling my iPad Pro 9.7 (I bought one with more storage, and am selling the smaller one). I bought it from Apple, put in my already activated AT&T sim and used it like that (never used the imbedded sim). Now that I'm selling it, I removed my sim, someone wants to know if it will work on Verizon. I honestly have no idea! I remember reading somewhere about Verizon blacklisting iPads that weren't used on their network first? But now I can't find the article. I don't have a Verizon sim to try out, so I'm having trouble answering this person.
