Pretty sure the problem would be far worse with VoIP. You're now getting several packets per second to measure.

  First the message goes to the server. Then it must wait for my client to pick it up which is not instantly. I cannot see how my location could be measured by picking up a message from a server.

    VoIP is voice. It's a realtime low latency point to point protocol. There are options to use intermediate servers, but there's a ton of room for information to leak.

      I meant SIP protocol VOIP that can also send and receive SMS via a server.
