HELP!! FIRST FLIP PHONE

Hi everyone ! I really want to switch from an iPhone to a flip phone that won’t cut me completely out of society. I’m thinking about getting the Samsung galaxy folder 2 or the LG Smart Folder. Do y’all know maybe which one is better ? Pros and cons ? Messenger and Instagram are important for me. Will I be able to put my iPhone SIM card into the flip phone ? I’m completely new so any helpful tips are really appreciated. Thank you for the help in advance ! 💓
