ota not getting update topic

Keeps saying my phone is up to date...I havent got the new ota though.

Do I need my sim in for att to let my phone have the update? I tried going back to stock with odin, but then put my sim in another phone to use. So the gs6 edge is only wifi.

this is the only reason I restored to stock, to grab the ota, now its saying my phone is already up to date.

any help would be appreciated...thanks
