No, verizon will not work with the GSM part of the kit. You need the sim for verizon. They are cheap. 7 bucks on amazon. Don't order it from straight talk. They never sent mine. Fed ex said they got the postage made out but no product to send...... Not sure if HTC 1 Max is compatible or not. But LET US KNOW!! If you ever get it to work. Thousands want to know what verizon phones do and do not work with ST BYOP! I know the galaxy note 4 DOES work. And the lg g vista does NOT work.
