Oppo has a reputation for clever smartphones, but there's a good reason why you rarely see its devices in the US: it hasn't had local LTE data until the Find 7.
Anyway, we found a version of the R1 with US-capable LTE, fresh from FCC approval. The high-style, low-cost phone can now handle 4G data on T-Mobile and, to a limited extent, AT&T. It should also run quickly on Canadian providers.
Given the lack of network branding, it's more likely to be sold in unlocked form to fans of the R1's looks and extra-bright f/2.0 aperture camera.
