It absolutely will. They will not be able to participate in almost all modern social interactions. Like, yeah, they will be able to talk to their friends, but only when at school and at sleepovers.
And even then, being excluded from having normal access to a phone still isolates them from "normal" people. Everyone pulls out their phone and all the phoneless person can do is either sit there in jealous silence like a loser or try to get everyone to stop playing on their phones when they're around them (also like a loser).

Overall not an ideal situation.
