Nobody can restrict your communication. I just finally got my dad into an access restricted but semi-independent home (memory-safe) and hes got a brand new huge TV, complete WiFi and balcony with the freedom to walk to the farmers market two blocks away and several upscale restaurants and vendors across the street. He and I talk dozens of times a day when Im not there. Theres a community room that he can chat with the few other residents and have coffee and a bagel while going out on the gardened roof to attempt pickleball. I cook most of his food but he is free to cook for himself. Its just an apartment with all the amenities youd expect. Nobody will ever restrict you from having a phone or anything else, and nobody can stop you from either calling family or going home. Youre a grown-ass adult.
Edit to add: I understand, after helping my dad through a similar transition, how much anxiety it can inspire. The assumption that youre no longer going to be self-sufficient, which youve been all your life, Ive seen first-hand and it doesnt need to be terrifying.
Dad is extremely happy in his new home. Hes independent, has freedom, hes free to come and go (sometimes with supervision - me), cooks and eats what he wants for himself, has friends, watches baseball all day (thats our sport), socializes with fellow residents and talks on the phone with his extended family every day. Nobody will ever take that away from you. It only costs my trust $7200/month, but thats why I built a trust.
Im usually the one to drive him to dialysis at 05:00, but my sister picks him up at 10:30 most days, then hell sleep after a bit to eat and Ill send him a text about the days game and hell reply. We just went to an MiLB game last week and he was SO happy!
Its just an apartment. Do what you like, and good luck! Best to you.
