Galaxy S20 Phone not activating with old Galaxy SIM Card

Cannot get my new galaxy s20 to activate when my old galaxy's sim card is inserted. The AT&T guy at the store deactivated my old phone so it doesn't work there either. Went to AT&T's activation website and it said there are no phones eligible to activate on my line.

Where is the new sim card?   The guy at the store activated the new sim, which automatically deactivated the old one.

Thanks LizDance40! We said no to a new SIM card at the store because we were told the old one will work in the new phone.

Well oops. The old sim was deactivated, which happened when a new one was activated with your number.  

No idea why they let you leave with a non working sim.

Interesting, thank you for the input. They told us that the old SIM would work in the new phone.... is that not the case?

Not after they activated the new one, as required.
