OTG Compatible Phones on Visible?

[why1942]

My current visible phone ZTE R2 and it is not OTG compatible (cannot connect phone to external flash drives, card readers, etc). I would like to upgrade to the Samsung Galaxy A21, as a search online states this phone is OTG compatible, but there is no mention of it on the visible website and the customer service chat people have no idea what OTG even is. Makes me wonder if there are no phones offered by visible that are OTG capable. 

Does anyone have a Visible phone (even better the Samsung Galaxy A21) that is actually OTG?

The one phone I’ve used that I know has OTG is the Samsung Galaxy A11. If the phone is listed on the manufacturers website as having OTG then it should have it! Visible has nothing to do with a phone having it or not
