Unlock AT&T cell phone
Dear, for my last birthday I received a AT&T Kyocera Duraforce Pro, shipped via Amazon to The Netherlands (where I live). The phone works great, but when I enter my simcard, I can only call, and not use internet. Now I guess this is related to the lock/unlock status of the phone. But requesting to unlock does not work, the automatic email is not confirmed back. And now, I receive the following message: "Hmm...looks like there's an unpaid balance linked to your device, so we can't unlock it." I'm new to AT&T, never used their services, so I'm wondering to do here?
Things in short: how can I unlock this device so I can use internet in Europe? Thanks!
