In order to install a firmware update on a no longer activated iPhone, or restore a no longer activated iPhone with iTunes if wanted or needed, the no longer activated SIM card must be inserted in the iPhone in order to complete the process.
If the seller restored the iPhone with iTunes as a new iPhone or not from the iPhone's backup without the SIM card used with the iPhone inserted before selling it, the process was not completed.
If this is an AT&T carrier locked iPhone, you will need to activate the iPhone with AT&T in order to use it, or have the seller send you the no longer activated SIM card that was used with the iPhone when it was activated, which isn't likely.
If an AT&T carrier locked iPhone, you will need an AT&T SIM card inserted in order to activate the iPhone.
I'm not aware of a way to get around not having the no longer activated AT&T SIM card that used with the iPhone when it was activated inserted in the iPhone in order to install a firmware update or restore the iPhone with iTunes if wanted or needed.
Any talk about getting around this will likely involve hacking, which is against Apple's license agreement for the iPhone and cannot be discussed here.
