Okay, so on the non-budget side, I pay ~$64/mo for T-mobile's "unlimited[1]" plan and a Google Pixel phone. ($57/mo for the service, and I've amortized the phone price to ~$7/mo based on my lifetime average phone lifetime. Even if you amortize the phone over only its ridiculously short warranted lifetime, that's $42/mo for the phone, or $99/mo, but that implies purchasing a new phone yearly, which most people do not do (the average phone lifespan is just under 3y).)

[1]: (n.b., the plan is not truly unlimited.)
