Issue with installing whatsapp on Samsung galaxy tab A

[AC Question]

Hi, I recently bought a Samsung galaxy tab A (SM-T280). I used to have an ASUS tablet and the way I know to install whatsapp on an android tablet is by going to the download page then verify my number through a call after installation, but when I followed the same steps it wouldn't either send a confirmation text or a call, and I keep getting a message that it cannot verify my number and I have to retry in 1 hour. Any help will be deeply appreciated, thank you.
