OnePlus is kicking off its first open sale for the OnePlus 2 on October 12, allowing customers without an invite to purchase the handset. The vendor will have the phone up for sale for one hour, starting at 12PM, across several time zones.

Here's when you'll be able to buy the device sans an invite on October 12:

Asia: 12:00-1:00 pm HKT
Europe: 12:00-1:00 pm CEST
North America: 12:00-1:00 pm PDT​, 3:00-4:00 pm ET
OnePlus has mentioned that the time slots will be region-locked, meaning that customers in the US will be able to purchase the handset only during the 12PM to 1PM PDT window. The vendor also stated that Indian buyers will be able to buy the phone on Amazon India from 12PM to 1PM without an invite.

You can buy a maximum of two phones per order, but you can place as many orders as you want during the one-hour window. Estimated shipping time for your order will be shown during checkout. How many of you are interested in picking up the OnePlus 2 in three days' time?

That will be between 8pm and 9pm on Monday in Nigeria
