Question New phon

[Rludington]

I have a couple older galaxy phones, an s7 and s8. If I buy a new phone Galaxy or otherwise, can you take the Sim card from the old , put it in the new and do a data !/ app transfer... and the new phone will work picking up the old phones number ? Currently on att so new phone would need to be unlocked. I would probable buy one of the new galaxy, a s21 fe maybe.
