I'm very much a mobile phone newbie.
I bought one of the deals mentioned here & have had nothing but trouble.
The latest, and worse, is that it's not recognising my sim card (which has been tested on other phones).
I've taken it to three repair places (including Optus who I am with). Two didn't have a clue but the third one said it looks as though it's locked!!
What does this mean & how can I get it unlocked? It's a Nexus 5X
Thanks for any advice
Larry
The phone is service provider locked. Like say locked to telstra so you cant use an optus sim. Only in your case the service provider is overseas.
