What you bought may not be what you expect... I am speculating here but you may have an GSM/LTE version of the logic board inside a regular housing. There is a hardware "fix" that allows you to circumvent iCloud locked LTE boards. It allows them to function as a WiFi-only model though. Where exactly did you get this iPad? Do you have any recourse or ability to find out more about it's history?
