The Lumia 550 will reportedly be priced to compete with devices in the entry-level market segment, with the latest disclosure suggesting it could be around €120 (£88). A screenshot of the database listing and the specifications were first put out by German site, and were later corroborated by Windows Central, which managed to dig out a few more details including a removable SD card, on-screen key and metal finishing around the display.

The Lumia 550 will replace the Lumia 640, which was unveiled alongside the Lumia 640 XL at the 2015 Mobile World Congress convention and it looks similar to the Lumia 640. The device is also said to sport a dual LED flash, positioned in the upper right-hand corner. On the opposite left is the front-facing camera, says Windows Central, which claims to have obtained access to a prototype model of the Lumia 550. Speculation hints it could be an Iris scanner, which is expected to be meant for flagship series only.

Microsoft has already sent out invitations for an event related to Windows 10 devices scheduled for 6 October. The company is expected to take the stage to unveil Lumia 950, 950 XL, Surface Pro 4 and Microsoft Band 2. The Lumia 550 might come at the same event.
