Interesting concept, especially since it has Android it could be a dedicated media player. However, being Wi-Fi only really restricts what you can use and it having only 32gb of space means you can't really store much offline.
LD_TypeNot sure if this is a different version or not, but all other information I have seen for these indicate they can be 4G SIM enabled. You can even see the SIM slot on the left side of the device. That said, reviews are spotty (poor sound, poor UI). Seems like an interesting concept, executed with mediocrity. Too bad, I actually really enjoy the IKKO OH10s. There's a 20-min review on YT: https://www.youtube.com/watch?v=ILSEXlDXV9U
