Nokia has announced a press event on April 2, when it is expected to unveil the new Lumia 930 and Lumia 630.

Previous rumors have suggested that Nokia might take the wraps off the Lumia 930 and Lumia 630 during Microsoft's BUILD 2014 conference, and it so happens that April 2 is the very first day of that conference.

The Finnish company announced this upcoming event on its Nokia Conversations blog, in a post titled "If you BUILD it, they will come." Microsoft, meanwhile, is expected to reveal its new Windows Phone 8.1 operating system at the conference. The most likely scenario is that the two companies will team up and introduce the new OS, along with new Nokia smartphones running the latest Windows 8.1 at this year's BUILD Developer Conference.

"What makes 2014 so special is the exciting Microsoft and Nokia partnership, and boy, have we got some treats lined up for you," Nokia touts in its blog post.

The rumored Nokia Lumia 630 is reportedly codenamed "Moneypenny," and has leaked on several occasions so far. The handset is expected to launch in both single- and dual-SIM versions, which would make it the first Windows Phone with dual-SIM support.

Rumored Lumia 630 specs include a 4.5-inch display, a Qualcomm Snapdragon 200 or 400 processor, 1GB of RAM, and Windows Phone 8.1 out of the box. Connectivity options should consist of LTE, HSPA+, EVDO, and TD-SCMA support. After the handset made its way through the FCC back in February, trusted tipster @evleaks has also posted an image of the purported Lumia 630 earlier this month, showing on-screen navigation keys. The smartphone is also rumored to come without a rear camera flash, which further suggests that it will be a budget offering.

The much-touted Nokia Lumia 930, meanwhile, is expected to launch as the global version of the popular Nokia Lumia Icon, which is currently available only in the U.S. as a Verizon exclusive. Very little details are available regarding this purported Nokia Lumia 930, codenamed "Martini," but the smartphone is expected to boast high-end specs and features and an elegant metal design.

With an event officially announced for April 2, chances are high that Nokia will unveil its new Lumia 930 and Lumia 630 Windows Phone 8.1 smartphones during the Microsoft BUILD 2014 conference. We'll be covering the event and bring you the latest news as soon as they become available, so stay tuned.
