Hi Hoping someone can help me... Long story but I'll try and shorten it.. A couple of weeks ago my mobile phone fell out of my pocket and smashed. I managed to retrieve my SIM card, I'm with Optus on a contract due to expire in October. Anyway, I went and got another pre-paid phone, just a cheap one. I HATE it, yeah I know you get what you pay for! And I use my phone alot. So I decided I would get another phone, so I went over to K-mart and got a better phone, unfortunately though I chose one that is a Telstra Pre-paid phone. I got back to work, put my SIM card in the new phone and of course it comes up with "enter restriction code"! Bugger!! So my question is does anyone here have any idea what the restriction code might be?? Kmart will not exchange or refund mobile phones!! Help! Is my only option to go to prepaid with Telstra?? And lose my current number??
