Sigh. It's possible to remotely, physically locate any O2 mobile customer at any time over the internet with a trivial method using their mobile phone number, due to O2's poor implementation of 4G Calling which, by design, gives away the Cell ID.

O2 VoLTE: locating any customer with a phone call

Privacy is dead: For multiple months, any O2 customer has had their location exposed to call initiators without their knowledge.

Thank you for the warning. In future years it may be usefull to hide from dictators (They increase their power step by step these days) and we need to know how technology can be used to track us.
Best end our O2 subscription.
Even better: talk with friends in person, travel to them by bicycle without navigation system, and leave your phone at home, switched off.
