Dz09 cards, got them from my phone. Now saying the SIM card is locked
My sister got me a DZ09 Bluetooth Smartwatch/Phone for Christmas. I tried going on Facebook, the Browser. twitter, and What's app. It said I needed a Valid SIM and SD Card. Now, I unmounted the SD Card from my Alcatel OneTouch Elevate, and also took the SIM Card Card. Luckily, it's not saying anything about the SD Card now. But one issue. It's saying: "The SIM Card has been locked. Please try Power Cycling the Device. If problem persists, Call Customer Support." Someone please tell me why. Is it because it's the wrong sized SIM Card? Something's messed up? Is it because I'm not with a Carrier for my Phone? On the front of the SIM Card, it says Sprint. Please help me, I would appreciate it.
