How does caller localization?



Hi,

A friend of mine had had a Mi4 for some months, with miui based on android 4.4.4 (if I'm not wrong). One thing that impressed me was that his phone was able to write on screen the city I was calling from when I was in another town here in Italy! I know there are some simple "localization" apps that just check a database to determine the city of a landline number, but in this case I was calling from a cellphone (a BlackBerry locked on 2G), so there was nothing to spot on a database except the fact it was an Italian cellphone.

My friend was using 4G, so I suppose the network sends some extra data to the phone about the city when a new call is coming.... and I know for sure my was not "cheating", because we checked several time with different cities and he was able to tell me where I was.

My friend now has another phone (LG G4) with Lollipop, and this feature it's not there anymore..

My question is: is it possible to have this feature on another android-based phone?

Thanks!

Ste
