Forgive me for being slow, but it's a loooooong time since I had any thing to do with PayG phones.
I ordered this one for my mum on TMobile:http://www.carphonewarehouse.com/mobiles/mobile-phones/ALCATEL-OT-S319/PPAY
I assumed that meant the phone would come locked to Tmobile and she'd be able to just put her existing TMobile sim in it and be away. However it has arrived today and when you turn it on the Orange logo shows and after entering her pin number she is asked for a 'Network Key'.
Have they sent me an Orange phone by mistake? Have I misunderstood what ordering that phone on TMobile means, or is something else going on entirely?
Thanks to any one who can enlighten me!
