After making its flagship phone available to buy without needing an invite, OnePlus has now opened up orders for the OnePlus X too.
"As we continue to move our business forward we will never stop looking for exciting new ways to reinvent ourselves. That's why we're excited to announce that, as of today, the OnePlus X is completely free," the company says in a blog posting.
The OnePlus X costs £199 to UK buyers, with free shipping. It is available in onyx, champagne and ceramic colour themes, and can be bought from the OnePlus online store.
A protective case adds up to an extra £19.99 to the bill.
