But could not use it anymore here in USA with a US sim card. The tech support told me that probably my phone is country lock. I had use different sim cards when I was still in the Philippines. But the phone has no signal bars when I insert my US sim card here.</P> Sat, 26 Aug 2017 00:40:50 GMT https://community.sony.rs/t5/z-series/country-lock/m-p/3565577#M112749 Jryvill 2017-08-26T00:40:50Z https://community.sony.rs/t5/z-series/country-lock/m-p/3565578#M112750 <P><A href="https://community.sony.co.uk/t5/user/viewprofilepage/user-id/1062998">@Jryvill</A></P><P>did it requested a pin to unlock the phone? was the phone network branded or locked to a carrier?&nbsp;</P> Sat, 26 Aug 2017 00:53:38 GMT https://community.sony.rs/t5/z-series/country-lock/m-p/3565578#M112750 Uliwooly 2017-08-26T00:53:38Z https://community.sony.rs/t5/z-series/country-lock/m-p/3565579#M112751 <P>No it did not asked any pin.&nbsp;</P><P>The sim card that I inserted was an AT&amp;T nano sim.</P> Mon, 28 Aug 2017 02:02:46 GMT https://community.sony.rs/t5/z-series/country-lock/m-p/3565579#M112751 Jryvill 2017-08-28T02:02:46Z
