Not just a cell phone, but a *smart phone* in a lot of cases. And a relatively up to date one too (as apps and QR codes are required).
My grandmother lives in rural Pennsylvania. She doesn't have internet. She does have a smart phone but all she knows how to do is call and receive texts. She had to have my aunt schedule her covid vax, and my aunt had to come up with her laptop and mobile hotspot so that she could do a required virtual medical appointment before her hip surgery.
You can't apply for a job anymore without internet access, a cell phone is expected, etc. There's a growing push to have internet access regulated as a utility in the US because, like phone, electric, water and (maybe) gas, you need it to function in society.
