You can now pre-order the unlocked Essential Phone at Best Buy
Sprint is the only carrier in the United States that offers the Essential Phone, but the unlocked model can be had via Amazon, Best Buy, and Essential's online store.
However, customers who want to pick up the 360-degree camera along with the Essential Phone will have to pay an extra $50. The price is available for a limited time, but the camera is likely to be available later than the phone.
Moreover, you can add an extended care for $99, which will get you 2 years of coverage for breakdowns and accidental damage. Unfortunately, you can only buy the black color version of the Essential Phone at Best Buy or on the company's website.
