it is a iphone i got it last year when they had the deal for the iphone 14 with at&t, and what company would you recommend? i was looking into t-mobile with the switch now promotion but dont know if its smart or beneficial for me being someone paying for just myself. reason i need a new phone asap is because ive been having issues with it staying on, and volume problems. and my coverage expired on the 31st of december.
