The Lumia 630 comes in two flavours – single-SIM and dual-SIM variants – and offers 3G connectivity, but for those wanting to live life in the fast lane, the Lumia 635 includes 4G LTE support.
Nokia already revealed that the 635 would make its way to T-Mobile US; ever-reliable leaker @evleaks has now joined some dots for us by revealing that the specific T-Mo variant of the device is the 'Monarch' - a Nokia device codename that has been floating around for several weeks. It remains unclear, however, whether the carrier has made any significant changes to the device’s spec sheet.
Nokia announced that the Lumia 635 will be priced at around $189 (off-contract and before taxes and subsidies) when sales begin next month. It will likely be a few more weeks before T-Mobile announces exact pricing details for the device on its network. The handset will also be sold on AT&T and Boost in the US.
While T-Mobile has sold a range of Windows Phones over the years, its support of those devices has been mixed. The carrier’s exclusive mid-range Lumia 810 is no longer on sale and no longer supported, despite being just 18 months old, meaning that owners of the handset will not get the upcoming Windows Phone 8.1 update. Similarly, T-Mobile refused to update the Lumia 710 to Windows Phone 7.8 last year, leaving users stuck on version 7.5.
