Got the text about the increase and it's definitely nail in the coffin for me. I've confirmed that I don't need much data even with forgetting to reconnect to wifi.
Strangely found myself tempted towards Helium Mobile since it's 20 bucks for "unlimited" with 30GB of high speed. But of course it's a crypto product... I'd been planning to wait til they release a feature to supposedly cryptographically protect against SIM swap attacks here. Assuming it checks out for security I'd consider it a decent extra benefit. Thoughts?
edit: forgot to mention they're a tmobile mvno. so not exactly completely getting away from them.
