One Plus is a phone maker that sells its products through unconventional means. Here's an overview of how One Plus works and what it means for you. Thanks to technological advances, hard powered hardware such as smart phones are getting cheaper to build. Which means more and more companies have the means to design and sell them. One plus is one of the smallest upstarts out there and one of a handful of Chinese companies trying to break into a very competitive market. To date they have only made a few smart phones, the one plus one in 2014, the one plus two which went on sale earlier this year, and now the angular one plus x. Which comes in either glass or in limited edition ceramic versions. All three phones offer powerful technology such as big high resolution screens and powerful processors and use custom versions of Google's Android operating system. With price tags much cheaper than other flagship phones, the OnePlus mobiles that have gone on sale so far have earned positive reviews. But what really sets the company apart from other makers of phones is how you get it's product. Instead of buying from a shop or online to date OnePlus has sold its phones using an invite system. Whereby to get one of the mobiles you need to secure an invite. Either from someone who's already bought one of the phones or by joining in with competitions or promotions. The invite system helps OnePlus carefully control stock but has also served to create A strong fan further around the brand making OnePlus a favorite for passionate Android users. These powerful mobiles aren't for everyone however. And something to consider is that because it's a smaller company, OnePlus may not be able to offer the same level of customer support you'd get if you buy from a much larger firm. Whether or not you want to buy one of it's phones however one plus is interesting because it shows that there are new and interesting ways to distribute tech. And prove there is scope for smaller organizations to challenge the products put out by major players like Apple or Samsung.
