What TheKindleWorm said.

Also, a SIM card comes installed inside the K3. The device is not meant to be opened by the customer, so you will probably never see it.

The K3's anywhere internet, without a monthly fee, is a tremendous bargain, but there are limitations which hold down bandwidth uses. The browser is best with text-heavy web sites optimized for cell phones.

You cannot make phone calls with the K3. There is a microphone, but no released software to take advantage of it. Could Amazon, from software, add an optional cell phone feature and charge a monthly fee for that? As for as I know, yes. Some of their existing customers would not like it. My guess is that they do NOT plan this because, if they did, the keyboard have included numeric characters.
