With Imei, The Mobile Device Can Be Made Ucalleable By National Networks, How About International Networks? Be Great If You Can Provide Experience Or Credible Reference Website On This. Even If Barred By All Networs, The Lost Phone,

I understand that with the IMEI, the mobile device can be made uncalleable by national networks, how about international networks? eg it might be barred use for calls in UK, but another country? be great if you can provide experience or credible reference website on this. even if barred by all networs, the lost phone, can still be used for other things right? eg camera, media player, browsing etc?

IMEI identifies the handset. No doubt calls can be barred if the service providers wish to. I doubt any app checks the IMEI before operating though.

I suspect it unlikely it would barred globally though. My understanding is that many stolen ones are shipped to certain African nations.

Wouldn't every network provider in the world have to block that IMEI for a phone to be blocked worldwide?
OG is right, there is a black market for blocked phones.

If a phone is blocked it will be unable to do anything that requires a mobile data connection nor will it be able to send/receive calls or texts. It certainly can't be used for browsing.
It may be wiped totally but that is not always the case, you may be able to access downloaded files and photos stored on the phone. The camera might still work.

I'd have thought it could still use WiFi in the original country.

BTW barry, just because I mentioned where I'd read stolen mobiles often go, there was no need to call it a black market :-O

Seems you are right about the WiFi, OG.
