  • 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.



  • Went down a research rabbit hole wondering about doing security research on these encrypted radios. Looks like you’d have a pretty hard time finding a legal way to do it considering it’s illegal to transmit encrypted per FCC rules. So though you can get the hardware on eBay for 100 bucks, even beginning to test for flaws is already a gray area. Probably have to rig something up to avoid transmitting at all. Plus a faraday cage? Modern solutions use AES256, so a major flaw in crypto implementation on top of a failure to rotate keys is the only likely avenue. Even if you found a vulnerability, reporting seems like it would be highly risky with the legal murkyness and arrest happy authorities.
