A New Anonymous Phone Carrier Lets You Sign Up With Nothing but a Zip Code

My thoughts:

  • It is still a MVNO so all that juicy location and traffic data will be available to the actual carriers and governments.
  • That pricing is a complete rip off.
    • Calyx themself literally offers a $500/year truly unlimited SIM, meanwhile Phrelli’s $1,020/year plan is capped to 40GB a month.
    • Visible has a stellar $25/month plan that is also truly unlimited, but hotspot is capped at 5Mbps. They take fake address & name without issue.
  • And the continued silence on the coup of Calyx is highly concerning.

My advice:

  • Use Wi-Fi where possible.
  • Always use Mullvad or Tor.
  • If you do use a SIM card give them minimal information and keep it in airplane mode when possible.
  • Use a VOIP service for phone number that is detached from SIM.
  • Also please be aware that many hotspot devices are highly insecure and often years behind security patches.
    • For example the popular GL.iNet MUDI received a firmware update on 2025-09-30, but is still running a Linux kernel from 2023-03-22.
