Which are the cheapest (Dual SIM) android devices that support LTE Band 28?

[AC Question]

GLO Mobile (NG) recently launched its 4G LTE Network in Nigeria on FDD Band 28. Thought this is a powerful band that travels far and has a strong in-building penetration, all the devices I came across that support this band are high end devices. I was wondering if there were cheaper android devices (preferable dual
SIM) out there that support this band?
