Hey there
It doesn't appear that Samsung themselves are offering Trade In on the A54 5g at the moment.
You may be able to get trade in via a network carrier and taking on a contract .
That said, a quick look at the recyclers is showing a value of about £10 for your A10s IF anything is offered at all.
Might be best to keep it as a spare and get the A54 5g via the Samsung Shop App where you may get a 5% discount.
