$15/mo non-data plan. Cheapest data plan through T-mobile is $30/mo(?). I’m ADHD and I like having times when I’m not distracted by an e-toy. I want to make utilizing the Internet a deliberate choice, not a default. If I’m taking a dump, I’d rather use the time to daydream — being connected 24/7/365 reduces creativity.
Frankly, if I could get away with only a landline professionally, I would. Fixed-line VoIP is a few bucks per month, cheaper than the cheapest cell plan.
