HEADWOLF FPad6 Purchased new. The original screen protector felt sticky, so I replaced it with a glass screen protector. I used it indoors, mostly for testing. I confirmed that SIM cards from Softbank and au MVNOs worked without any issues. I used it for about an hour a day for a week, but it doesn't suit my needs, so I'm selling it. It's almost new, but I have used it, so please be aware of this if you are particularly sensitive to such things. Thank you.
