Seeking Supplier of Wonde Proud M7 with 3G/4G Module

Hi Team!

Seeking supply of a sample Wonde Proud / Wondex / Navixy M7 device, in both single and extended (D2) battery formats, and with the new Gemalto Cinterion LTE modem.

They are available - somewhere - but are elusive to track down!

If anyone on the forum has any knowledge on the devices, would they kindly point me in the right direction?

Thanks in anticipation!
