I assume in order to be able to decide to serve those 1Ghz frequencies, all the phones are going to ping the local towers regardless, so it doesn't matter.

- opless 6y agoThat'll no doubt be down to the configuration of the terminal device. It'll likely only TX on the available bands allowed in the devices home region for licensing/compliance issues. Back on the tracking side of things... AFAIKR 3G and above do not leak their IMEI/IMSI unencrypted. Of course nearly zero phones show or warn if encryption is used or not (though I think that's a setting in the SIM card).
