IP Checker
With your proxy, phone or profile, open this page to see exactly what a website sees: the address, whether AT&T, T-Mobile or Verizon is behind it, the metro it resolves to, and whether browser time zone or WebRTC point elsewhere.

How to read it
The ISP shown for a SimProxies line is a US mobile carrier, since its address is in the carrier's pool and shared with many real phones via carrier-grade NAT. The resolved location is a metro or state, not a street. There are two ways an account gets given away: the browser time zone disagrees with the IP, or a WebRTC candidate exposes your home or office address. Correct both in the browser profile, then repeat this check.
