The editor weighs in — flanked by the optimist on her shoulder and the cynic on the other.
“For a WiFi-first device that needs a backup signal, paying only for what you use is the honest pricing model.”
“Not being able to manage this plan in the app in 2026 is a customer support nightmare waiting to happen.”
